Evaluation of Salivary Mucin, Amylase, Protein Profile, and Periodontal Parameters among Hypertensive and Diabetic Patients

Systemic and localized oral disease instigates alterations in salivary composition and content. The objective of the study was to evaluate the levels of salivary amylase, mucin, total protein levels, and periodontal inflammatory parameters in Type 2 Diabetes mellitus (T2DM), hypertensive (HTN) patients, and healthy controls. The study sample was divided into three groups: healthy, T2DM, and HTN. Salivary samples were collected from the included participants and salivary flow rate (SFR) and pH were measured. The salivary levels of amylase, mucin, and total protein concentration were analyzed using an enzyme-linked immunosorbent assay. The effect of anti-hypertensive and hypoglycemic drugs on the salivary flow rate, salivary pH, mucin, amylase, and total protein concentrations was evaluated. The results were analyzed with Chi-squared and analysis of variance to compare the means and standard deviations of variables among the study groups. SFR was significantly (p < 0.01) lower among diabetics (0.78 ± 0.45 mL/min) in comparison to healthy (1.52 ± 0.62 mL/min) and hypertensive (1.07 ± 0.7 mL/min) subjects. PISA values were significantly higher in T2DM (1029 ± 234.6 mm2) and HTN (799.4 ± 155.05 mm2) subjects when compared to controls, indicating a high inflammatory burden of oral cavity caused by these conditions, and showed statistically significant difference between the groups (p-value < 0.001). Mucin levels were significantly higher (p-value < 0.05) in hypertensive patients (4.6 ± 1.17 units) compared to diabetics (3.59 ± 1.03 unit/mL) and healthy (2.26 ± 1.09 units/mL) subjects. Amylase levels were significantly higher among healthy subjects (1.76 ± 0.75 mg/mL) compared to both hypertensive (1.33 ± 1.0 mg/mL) and diabetic (0.88 ± 0.57 mg/mL) patients. Total protein concentration was significantly raised (p-value < 0.001) in diabetics (37.67 ± 3.12 mg/mL) compared to healthy (29.3 ± 3.22 mg/mL) subjects. Significant differences in BOP, CAL, and PPD was observed (p-value < 0.001). Use of antihypertensive and hypoglycemic drugs showed a significant influence on salivary flow rate, protein, mucin, and amylase levels. T2DM and HTN induced irregularities in salivary flow rate, pH, amylase, and mucin levels and showed an increased incidence of moderate to severe periodontitis in patients. UWS levels of SFR, mucin, amylase, and total protein can be used as diagnostic and therapeutic biomarkers in patients with T2DM and HTN with oral disease.

Effect of Non-surgical Periodontal Therapy on the Clinical Periodontal Inflammatory Parameters in \(\beta\)-Thalassemia Major (TM-\(\beta\)) Patients with Gingivitis

Background: Increased prevalence of gingival diseases in thalassemia patients has been consistently reported. In diseases with neutrophil dysfunctions, periodontal tissue is lost very rapidly. \(\beta\)-thalassemia major (TM- \(\beta\)) patients exhibit defective neutrophils and macrophages. Therefore, supplementary gingival inflammation is detrimental to periodontal tissues in these patients. This warrants attention to specialized oral health care intervention in these patients. This is the pioneer pre and post study that evaluates the effect of non-surgical periodontal therapy (NSPT) in \(\beta\)-thalassemia major (TM- \(\beta\)) patients with gingivitis. And also reports the prevalence and distribution of disease severity in TM- \(\beta\)patients.
 Methods: 31 patients (15 females, 16 males) fulfilling the inclusion criteria were provided with protocol guided NSPT including scaling, polishing and chemical mouthrinse (0.2% CHX). Gingival index (GI), plaque score, Papillary bleeding index (PI) and periodontal pocket depth (PPD) were recorded with a periodontal probe (UNC-15) at baseline and evaluated after 6 weeks of intervention. Paired T-test was applied for GI, PBI and plaque and Wilcoxon signed rank test for PPD at the P-value of <0.05
 Results: 86% of the assessed individuals had gingivitis (6% -mild, 44%- moderate and 36% - severe). NSPT showed highly significant (P - <0.000) improvement from baseline to 6 weeks after intervention for all the clinical parameters, GI, PBI, plaque score and PPD.
 Conclusion: Within the limitations of the study, the results show that with proper protocol, multidisciplinary approach and careful screening of the patient’s systemic status, TM-\(\beta\)patients with gingivitis respond positively to local measures of plaque control.

Effect of tongue piercing on periodontal and peri-implant health: A cross-sectional case-control study in adults.

The authors hypothesize that periodontal and peri-implant inflammatory parameters are poorer in adult patients with tongue piercing compared with controls. The aim was to assess the influence of tongue piercing on periodontal and peri-implant health status in adults. Test and control groups comprised of individuals with and without tongue piercing, respectively. A questionnaire was used to collect information about gender, age, duration of tongue piercing and implants in function, jaw location of the implant, reasoning for wearing the tongue ornament, and oral hygiene and ornament cleaning habits. Full-mouth and peri-implant plaque index (PI), gingival index (GI), clinical attachment loss (CAL), probing depth (PD) and marginal/crestal bone loss (MBL and CBL, respectively) on mesial and distal surfaces of teeth/implants were recorded. The material (plastic or metal) from which, the bar and ball-ends of the ornament were fabricated was also recorded. A p<0.01 was considered statistically significant. Forty-eight and 49 individuals were included in the test and control groups, respectively. There was no difference in PI, GI, PD, CAL and MBL (mesial and distal) among individuals in the test and control groups. In the test group, peri-implant PI (p<0.01), GI (p<0.01), PD (p<0.01) and mesial (p<0.01) and distal (p<0.01) CBL were significantly higher in the anterior mandible compared with implants in other jaw locations. In the control group, there was no difference in peri-implant PI, GI, PD and CBL around implants placed in both jaws. Wearing tongue piercings could increase the risks of periodontal and peri-implant diseases particularly in the mandibular anterior segment.

Association of Upper Lip Coverage with Gingival Inflammation: A Cross-Sectional Study

Objective: As dryness is reported to be associated with inflammatory conditions in different body parts, incomplete coverage by upper lip may be responsible for gingival inflammation. The objective of the study was to assess status of gingival inflammation with reference to upper lip coverage.&#x0D; Materials and methods: Patients with plaque-induced gingivitis consisting of 38 individuals with incomplete upper lip coverage (ILC) and 38 individuals with complete upper lip coverage (CLC) were enrolled. Plaque index (PI), gingival index (GI) and bleeding on probing (BOP) were recorded in whole dentition excluding third molars. Bleeding/plaque ratio was also calculated for different regions of dentition. Logistic regression analysis was applied to examine association between BOP at labial sites of maxillary anterior teeth and upper lip coverage.&#x0D; Results: Significantly higher PI, GI, BOP scores and BOP/plaque ratio were noted at labial sites of maxillary anterior teeth in ILC group as compared to CLC group (p=.001, p=.011, p=.004 and p=.016 respectively). Significantly higher scores of BOP were found at labial sites than palatal sites of ILC group (p=.003). Regression analysis revealed that maxillary anterior labial sites in ILC group were 1.51 times more likely of having BOP (adjusted odds ratio 1.51, 95% confidence interval (CI) 1.13-2.03, p=.006).&#x0D; Conclusion: Incomplete upper lip coverage of maxillary gingiva is associated with higher periodontal inflammatory parameters at labial sites of maxillary anterior teeth.

Maternal periodontal status, oral inflammatory load, and systemic inflammation are associated with low infant birth weight.

Periodontal disease and pregnancy outcomes have been claimed to be associated with conflicting reports. The purpose of this study was to prospectively examine the association between maternal periodontal status, oral inflammatory load and serum C- reactive protein (CRP) level, and infant birth weight. A total of 156 pregnant women (age 26.62 ± 3.93 years) within the gestational age group of 13 to 32weeks participated in this cross-sectional study. Oral inflammatory load (OIL) was assessed in a salivary rinse sample using fluorescence microscopy. Clinical periodontal parameters were recorded and serum C-reactive protein level (CRP) was assessed. Participants were followed till delivery, details of parturition and infant birth weight (IBW) was recorded. OIL was significantly more in participants with mild and moderate periodontitis as compared to those with gingivitis in mid and late stages of pregnancy. Periodontal and systemic inflammatory parameters were positively correlated. A significant negative correlation was found between IBW and OIL (P=0.006) and serum CRP (P<0.001). The GI score (P=0.039), BOP% (P=0.023), serum CRP level (P<0.001) and oral polymorphonuclear neutrophil (oPMN) count (P<0.001) was significantly more in mothers delivering babies with low IBW. A multiple linear regression analysis showed that only oPMN (β=- 0.244, P=0.021) and serum CRP (β=- 0.226, P=0.019) were included in the best model (R2 =0.12, F(3,152)=7.15, P<0.001) for significantly predicting the infant birth weight. Poor maternal periodontal status, increased oral inflammatory load and increased systemic inflammation have an adverse effect on infant birth weight.

The Effect of Gaseous Ozone Therapy in Conjunction with Periodontal Treatment on Glycated Hemoglobin Level in Subjects with Type 2 Diabetes Mellitus: An Unmasked Randomized Controlled Trial

Background: It is established that inflammation is involved in the pathogenesis of Type 2 Diabetes Mellitus (T2DM) by promoting insulin resistance and impaired beta cell function in the pancreas. Among the hypothesized independent risk factors implicated in the pathogenetic basis of disease, periodontal infection has been proposed to promote an amplification of the magnitude of the advanced glycation end product (AGE)-mediated upregulation of cytokine synthesis and secretion. These findings suggest an interrelationship between periodontal disease and type 2 diabetes, describing poor metabolic control in subjects with periodontitis as compared to nondiabetic subjects and more severe periodontitis in subjects with T2DM as compared to a healthy population, with a significant positive correlation between periodontal inflammatory parameters and glycated hemoglobin level. Results from clinical trials show that periodontal treatment is able to improve glycemic control in subjects with diabetes. Many therapeutic strategies have been developed to improve periodontal conditions in conjunction with conventional treatment, among which ozone (O3) is of specific concern. The principal aim of this trial was to compare the clinical effectiveness of an intensive periodontal intervention consisting of conventional periodontal treatment in conjunction with ozone gas therapy in reducing glycated hemoglobin level in type 2 diabetic patients and standard periodontal treatment. Methods: This study was a 12-month unmasked randomized trial and included 100 patients aged 40–74 years older, with type 2 diabetes mellitus diagnosed. All the patients received conventional periodontal treatment, or periodontal treatment in conjunction with ozone gas therapy in a randomly assigned order (1:1). The primary outcome was a clinical measure of glycated hemoglobin level at 3, 6, 9 and 12 months from randomization. Secondary outcomes were changes in periodontal inflammatory parameters. Results: At 12 months, the periodontal treatment in conjunction with ozone gas therapy did not show significant differences than standard therapy in decreasing glycated hemoglobin (HbA1C) level and the lack of significant differences in balance is evident. Conclusions: Although the change was not significant, periodontal treatment in conjunction with the gaseous ozone therapy tended to reduce the levels of glycated hemoglobin. The study shows a benefit with ozone therapy as compared to traditional periodontal treatment.

Effectiveness of scaling and root planing with and without adjunct probiotic therapy in the treatment of chronic periodontitis amongshammausers and non‐users: A randomized controlled trial

Effectiveness of scaling and root planing (SRP) with/without adjunct probiotic (Lactobacillus reuteri) treatment towards the reduction in periodontal inflammatory parameters (clinical attachment loss [AL], marginal bone loss [MBL], plaque index [PI], and bleeding on probing [BOP] in shamma users and non-users [controls] with chronic periodontitis [CP]) remains uninvestigated. The aim of the present randomized controlled trial was to compare the efficacy of SRP with and without adjunct probiotic therapy (PT) in the treatment of CP among shamma users and controls (individuals not using tobacco in any form). The study was conducted in accordance with the Consolidated Standards of Reporting Trialsguidelines. Patient demographics were recorded using a questionnaire. Therapeutically, patients were allotted into four groups as follows: 1) group 1: Shamma chewers that underwent SRP alone; 2) group 2: Shamma-chewers that underwent SRP + PT; 3) group 3: Non-chewers that underwent SRP alone; and 4) group 4: Non-chewers that underwent SRP + PT. Periodontal parameters (PI, BOP, PD, clinical AL and mesial and distal MBL) were measured on all teeth except third molars at baseline and at 3- and 6-month follow-ups. Level of significance was set at P<0.05. In total, 31, 32, 31, and 33 individuals were included in groups 1, 2, 3, and 4, respectively. Among shamma users, there was no significant difference in the scores of PI, BOP, PD, clinical AL and MBL when SRP was performed with/without adjunct PT. Amongst controls, SRP with adjunct PT was more effective in reducing PI (P<0.05), BOP (P<0.05) and PD (P<0.05) at 3-month follow-up. There was no significant difference in periodontal parameters at 3- and 6-month follow-ups in patients that underwent SRP with and without adjunct PT. Habitual shamma use compromises the outcome of SRP in patients with CP. Among patients that do not use any form of ST product, SRP is an effective treatment modality for the treatment of CP, and this relationship is independent of use of adjunct PT.

Impact of Periodontal Inflammation on Nutrition and Inflammation Markers in Hemodialysis Patients.

Background: Malnutrition-inflammation complex syndrome (MICS) is a common and usually concurrent condition occurring in patients undergoing hemodialysis (HD), with a pathogenesis linked to biological and in situ environmental traditional risk factors. Periodontitis, one of the major types of infection-driven inflammation, often co-occurs in the in the hemodialysis population and correlates with markers of malnutrition and inflammation, such as albumin, creatinine, and C-reactive protein. Aim: The present study aimed to determine whether the periodontal inflammatory status parameters correlate with the albumin, creatinine, and C-reactive protein serum concentrations in HD patients, and investigate whether periodontal treatment improves these markers of nutritional and systemic inflammation. Materials and Methods: The serum creatinine, albumin, and C-reactive Protein (CRP) levels were measured at baseline and after non-surgical periodontal treatment, at 3 months and 6 months. Results: At 3 months, a significant correlation between plaque index and C-reactive protein (p = 0.012), bleeding on probing and C-reactive protein (p < 0.0019), and clinical attachment level and C-reactive protein (p = 0.022) was found. No significant correlation was found between clinical periodontal parameters and nutrition markers at each time. Conclusions: Our results confirmed the association between C-reactive protein serum concentration and periodontal inflammatory status, but further research is necessary to identify the contributing role of periodontitis on the onset and progression of MICS.

Impact of cigarette smoking and vaping on the outcome of full-mouth ultrasonic scaling among patients with gingival inflammation: a prospective study.

There are no studies that have assessed the oral soft tissue response to full-mouth ultrasonic scaling (FMUS) among cigarette-smokers (CS) (group 1), individuals vaping electronic-cigarettes (E-cigs) (group 2), and never-smokers (NS) (group 3). The aim was to assess the impact of cigarette smoking and vaping on periodontal tissues following FMUS. In a clinical prospective study, 89 male individuals were divided into three groups: CS (group 1), E-cig users (group 2), and NS (group 3). A questionnaire was used to gather demographic data and information regarding duration and daily frequency of CS and vaping. Full-mouth plaque index (PI), bleeding on probing (BOP), clinical attachment loss (AL), and probing depth (PD) were measured at baseline and 3 and 6months after FMUS (without root surface debridement). Numbers of missing teeth (MT) were also recorded. In groups 1, 2, and 3, 30, 28, and 31 individuals, respectively were included. In group 1, there was no statistically significant difference in mean PI and PD and numbers of sites with PD ≥ 4mm at 6 months' follow-up compared with baseline and 3 months' follow-up. In groups 2 and 3, there was no significant difference in PI, BOP, and PD at 3 months' (P > 0.05) and 6-months' (P > 0.05) follow-up. There were no pockets with PD ≥ 4mm at 3 and 6months' follow-up in groups 2 and 3. There was no difference in the numbers of MT and none of the individuals exhibited clinical AL in all groups. Following FMUS, gingival inflammation is worse in CS compared with individuals vaping E-cigs and NS. Periodontal inflammatory parameters are worse in cigarette-smokers than individuals vaping electronic cigarettes and never-smokers following FMUS. However, these findings should be interpreted with extreme caution as a number of factors may have influenced the present results.

Effect of Periodontal Therapy on Salivary Total Protein, TNF-alpha and IL-1 beta in Chronic Periodontitis Patients

Objective: Periodontitis is a chronic infectious inflammatory disease of tissues surrounding and supporting the teeth, it causes by microbial plaque accumulation and its severity depend on interaction between pathogenic bacteria&#x0D; and host immune response. This study aimed to evaluate the effect of scaling and root planning on the mean values of salivary total protein (TP), tumor necrosis factor-alpha (TNF-α) and interleukin 1 beta (IL-1β).&#x0D; Methods: Comparative study conducted on 40 volunteers: 20 of them with chronic periodontitis and 20 with healthy periodontium. Scaling and root planning was conducted for chronic periodontitis patients and unstimulated&#x0D; saliva was collected from all studied subjects at baseline before and after 4 weeks of periodontal treatment to estimate the mean levels of TP, TNF-α and IL-1β.&#x0D; Results: High mean values of clinical periodontal inflammatory parameters (plaque index, gingival index, probing pocket depth and clinical attachment loss), TP, TNF-α and IL-1β were detected in chronic periodontitis patients as compared to controls (p&lt;0.000), and significant reduction in their mean values were seen after 4 weeks of periodontal therapy as compared to baseline before treatment (p&lt;0.000).&#x0D; Conclusions: Biochemical (TP) and immunological parameters (TNF-α and IL-1β) detected at increased levels in chronic periodontitis patients and reduced after periodontal therapy, so further studies are necessary to evaluate the diagnostic and prognostic values of these markers.

Self-perceived oral symptoms and periodontal status among young intravenous heroin addicts: A cross-sectional case-control study.

It is hypothesized that (a) self-perceived oral symptoms (OSs) are worse in intravenous heroin addicts (IHA) than controls; and (b) clinical periodontal inflammatory parameters (plaque index [PI], bleeding on probing [BOP], PD and clinical attachment loss [AL]), number of missing teeth (MT), and radiographic marginal bone loss (MBL) are higher in IHA compared with controls. The aim was to compare the self-perceived OSs and periodontal parameters among young IHA and controls. Sociodemographic data, self-perceived OSs and duration and daily frequency of intravenous heroin use was gathered using a structured questionnaire. Full-mouth PI, BOP, PD, and clinical AL were measured, and number of MT were recorded. Mesial and distal MBL on all teeth was measured on digital radiographs. Odds ratios (OR) with 95% confidence intervals (CI) were computed for self-perceived OSs and periodontal parameters were assessed using the Mann Whitney U-test and logistic regression analysis. Sample-size was estimated, and level of significance was set at P<0.05. OR (95% CI) for self-perceived loose teeth (P<0.001), pain in teeth (P<0.001), dry mouth (P<0.001), burning sensation in mouth (P<0.001), bleeding gums (P<0.001) and pain during chewing (P<0.001) were significantly higher in the test than control group. Number of MT (P<0.05), PI (P<0.05), clinical AL (P<0.05), and mesial (P<0.05) and distal (P<0.05) MBL were statistically significantly higher among individuals in the test group compared with the control group. Self-perceived OSs and periodontal inflammatory parameters were worse in IHA than controls.

High Glucose-Mediated Cytokine Regulation in Gingival Fibroblasts and THP-1 Macrophage: a Possible Mechanism of Severe Periodontitis with Diabetes

Background/Aims: Diabetic patients are susceptible to severe periodontitis, but the precise mechanism is not fully understood. Aim of this study was to explore the biological pathogenesis of severe periodontitis in diabetic patients focusing on the crosstalk of human gingival fibroblasts (HGFs) and macrophages. Methods: A total of 70 periodontitis patients with or without diabetes mellitus (DM) were enrolled, and the statistical relationships of diabetic conditions to the periodontal inflammatory parameters were examined by cross-sectional study. In in vitro study, HGFs cell line CRL-2014® (ATCC) and differentiated THP-1 macrophages were cultured with normal glucose (NG: 5.5 mM) or high glucose (HG: 25 mM) condition, and treated with indicated inflammatory factors such as calprotectin (CPT), interleukin (IL)-1β and IL-6. To examine the effects of HG on soluble IL-6 receptor (sIL-6R) production in THP-1 macrophages, the supernatants were collected and the sIL-6R levels were measured by ELISA. To examine the effects of HG on IL-1β or IL-6-induced matrix metalloproteinase (MMPs) production in HGFs, the supernatants were collected. Levels of MMP-1 and tissue inhibitor of MMP-1 (TIMP-1) were measured by ELISA. Finally, after conditioned medium (CM) from THP-1 macrophages cultured with NG or HG conditions was collected, HGFs were treated with the CM. The supernatants were collected 24 hours later and the levels of MMP-1 and TIMP-1 were measured. To examine the specific effects of IL-1β contained in CM on MMP-1 and TIMP-1 production in HGFs, IL-1 receptor antagonist (IL-1ra) was used. Results: There were statistical correlation between IL-1β and sIL-6R levels in gingival crevicular fluid (GCF) and HbA1c in periodontitis patients with DM (IL-1β: P=0.035, sIL-6R: P=0.040). HG and CPT significantly induced sIL-6R production in THP-1 macrophages. HG significantly enhanced IL-1β or IL-6/sIL-6R-induced MMP-1 production in HGFs. The increase of MMP-1 by both IL-1β and IL-6/sIL-6R was significantly inhibited by specific ERK or IκB inhibitors. Corresponding to the regulation of MMP-1 production, HG condition increased the phosphorylation of p44/42 MAPK and IκBα in HGFs treated with IL-1β or IL-6/sIL-6R. Finally, MMP-1 production in HGFs cultured with HG increased significantly by CM from THP-1 macrophages cultured with HG. The induction of MMP-1 by the CM from THP-1 macrophages cultured with HG was significantly inhibited by dose dependent of IL-1ra in HGFs cultured with HG. Conclusion: Diabetic conditions such as HG induce IL-1β and sIL-6R production from macrophages in inflammatory periodontal tissues and may exacerbate the periodontitis synergistically via MMP-1 production from HGFs.

Comparison of periodontal inflammatory parameters among habitual gutka-chewers and naswar-dippers: a split-mouth retrospective clinical study

Objective: The aim of the present split-mouth retrospective study was to compare the clinical periodontal parameters among gutka-chewers and naswar-dippers.Methods: A structured questionnaire was used to record demographic information. Jaw quadrant in which, gutka or naswar were placed were defined as “test-sites”. The remaining jaw quadrants were designated as “control-sites”. Clinical [plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment loss (CAL)] and radiographic [alveolar bone loss (ABL)] parameters were compared among gutka-chewers and naswar-dippers in the test- and control sites. Data were analysed using non-parametric Wilcoxon signed rank test followed by post hoc analyses with the Bonferroni correction. p < .05 were considered statistically significant.Results: Seventy-five gutka-chewers and 72 naswar-dippers with mean ages of 45.2 ± 0.8 years and 47.3 ± 2.8 years, respectively were included. Gutka-chewers and naswar-dippers were consuming their respective smokeless tobacco product 10.2 times and 8.5 times daily for 15.1 ± 2.7 and 12.3 ± 3.4 years, respectively. Among gutka-chewers and naswar-dippers, scores of PI, BOP, PPD ≥4 mm, CAL and ABL were significantly higher in the test-sites compared with their respective control-sites (p < .01).Conclusions: Periodontal inflammatory parameters were poorer in the test-sites among gutka-chewers and naswar-dippers compared with the control-sites.

Periodontal Disease in Patients with Ankylosing Spondylitis: myth or reality?

Although the relation between periodontitis (PD) and systemic disorders (e.g. cardiovascular diseases, diabetes and rheumatoid arthritis) is widely accepted, the association with ankylosing spondylitis (AS) is inconsistently mentioned. We prospectively examined the relationship between periodontal disease and AS, focusing on the rate and course of PD, factors associated with severity and the impact of anti-TNF-a treatment on inflammatory status. Standard assessments performed twice (week 0, week 24) included an extensive dental evaluation (plaque index, gingival index, bleeding on probing, periodontal pocket depth, clinical attachment loss), inflammatory parameters and AS activity scores (BASDAI, ASDAS-CRP). More than half of AS presented with impaired periodontal health at baseline (mild to moderate PD) meaning increased sites with dental plaque, abnormal bleeding, increased periodontal pocket depth and clinical attachment loss. Significant positive correlation between presence and severity of PD, AS activity and systemic inflammation (CRP) was reported at baseline (p[0.05). A final analysis performed at 24 weeks revealed significant improvement in periodontal status, inflammatory parameters and AS activity, suggesting efficacy of TNF inhibitors directed not only against systemic, but also on local (articular, periodontal) inflammation (p[0.05). Patients with AS are at risk to develop periodontal disease, particularly those with high levels of systemic inflammation. Benefits of anti-TNFa therapy in the particular settings of AS patient and concomitant periodontal disease should be validated through further studies in larger cohorts.

Comparison of periodontal and peri-implant inflammatory parameters among patients with prediabetes, type 2 diabetes mellitus and non-diabetic controls

Objective: The aim was to compare periodontal and periimplant inflammatory parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD] and marginal bone loss [MBL]) among patients with prediabetes, type-2 diabetes mellitus (T2DM) and non-diabetic controls.Materials and methods: Forty-five patients with prediabetes (Group-1), 43 patients with T2DM (Group-2) and 42 controls (Group-3) were included. Demographic data was recorded using a questionnaire. Full mouth and periimplant clinical (PI, BOP and PD) were assessed and the radiographic MBL were measured on digital radiographs. In all groups, haemoglobin A1c (HbA1c) levels were also measured. p values less than .05 were considered statistically significant.Results: The mean HbA1c levels of participants in groups 1, 2 and 3 were 6.1%, 8.4% and 4.8%, respectively. The mean duration of prediabetes and T2DM among patients in groups 1 and 2 were 1.9 ± 0.3 and 3.1 ± 0.5 years, respectively. Periodontal and periimplant PI, BOP, PD and MBL were higher in groups 1 (p < .05) and 2 (p < .05) than group 3. There was no difference in these parameters in groups 1 and 2.Conclusions: Periodontal and periimplant inflammatory parameters were worse among patients with prediabetes and T2DM compared with controls; however, these parameters were comparable among patients with prediabetes and T2DM.

Efficacy of scaling and root planning with and without adjunct Nd:YAG laser therapy on clinical periodontal parameters and gingival crevicular fluid interleukin 1-beta and tumor necrosis factor-alpha levels among patients with periodontal disease: A prospective randomized split-mouth clinical study

Background and aimLimited evidence exists regarding the role of scaling and root planning (SRP) with adjunct neodymium yttrium aluminum garnet (Nd:YAG) laser therapy in reducing periodontal parameters (plaque index [PI], bleeding on probing [BOP] and probing pocket depth [PPD]) and levels of proinflammatory cytokines in the gingival crevicular fluid (GCF) among patients with periodontal disease (PD). The aim was to assess the effect of SRP with and without adjunct Nd:YAG laser therapy on clinical periodontal parameters and GCF interleukin 1-beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) levels among patients with PD. MethodsDemographic data was collected using a questionnaire. Mandibular right and left quadrants were randomly divided into test- (SRP+Nd:YAG laser) and control-sites (SRP alone). PI, BOP and PPD were assessed and GCF IL-1β and TNF-α levels were measured at baseline and at 3- and 6-month follow-up. Level of significance was set at P<0.05. ResultsTwenty-eight male patients with PD were included. At 3- and 6-month follow-up, PI (P<0.01), BOP (P<0.01) and PPD (P<0.01) were significantly higher in the control-sites than test-sites. In the test-sites, PI, BOP and PPD and GCF IL-1β and TNF-α levels were comparable at 3- and 6-month follow-up. At 6-month follow-up, IL-1β (P<0.05) and TNF-α (P<0.05) levels were significantly higher in control-sites than test-sites at 3- and 6-month follow-up. ConclusionAt 3- and 6-month follow-up, SRP+Nd:YAG therapy was more effective in reducing periodontal inflammatory parameters and GCF IL-1β and TNF-α levels compared with SRP alone.

Effect of Nd:YAG laser-assisted non-surgical periodontal therapy on clinical periodontal and serum biomarkers in patients with and without coronary artery disease: A short-term pilot study.

We hypothesized that nonsurgical-periodontal-therapy (NSPT) with adjunct Nd:YAG laser therapy is more effective in reducing periodontal inflammatory parameters (plaque index [PI], bleeding-on-probing [BOP], and probing-pocket-depth [PPD]) and serum interleukin-1beta (IL-1β) and matrix metalloproteinase-9 (MMP-9) levels in patients with and without coronary artery disease (CAD) than NSPT alone. The aim of this short-term pilot study was to assess the effect of NSPT + Nd:YAG laser therapy on periodontal parameters and serum IL-1β and MMP-9 levels in patients with and without CAD. A prospective randomized clinical study was conducted on 87 patients who were divided into two groups: Group-1: 44 patients with CAD and periodontal disease (PD) and Group-2: 43 patients with PD alone. Treatment-wise, these individuals were randomly divided into two subgroups: (i) NSPT alone and (ii) NSPT + Nd:YAG laser therapy. Demographic information was collected using a self-completed questionnaire. Periodontal parameters (PI, BOP, and PPD) and serum IL-1β and MMP-9 levels were measured at baseline and after 3 months of treatment. P-values <0.05 were considered statistically significant. At 3 months follow-up, PI (P < 0.01), BOP (P < 0.01), PPD ≥ 4 mm (P < 0.01), and serum IL-1β (P < 0.01) and MMP-9 (P < 0.01) levels were significantly higher in patients treated with NSPT alone than those treated with NSPT + Nd:YAG laser therapy. Among patients that underwent NSPT + laser therapy in both groups, periodontal parameters and serum IL-1β, and MMP-9 levels were comparable at 3-months follow-up. NSPT + Nd:YAG laser therapy may be more effective in reducing periodontal inflammation and serum IL-1β and MMP-9 levels in patients with and without CAD than NSPT alone. Lasers Surg.

Increased periodontal inflammation in women with preterm premature rupture of membranes

To evaluate possible differences in periodontal inflammatory, microbiological and clinical parameters between women with preterm premature rupture of membranes (PPROM) and controls with uncomplicated pregnancies. Fifty-six women (32 test (PPROM) and 24 controls (uncomplicated pregnancies)) were examined at three time-points (T1: gestational weeks 20-35, T2: within 48h after parturition, T3: 4-6weeks after parturition). The examinations included assessment of the Periodontal Screening Index, collection of gingival crevicular fluid (GCF) and subgingival as well as vaginal bacterial sampling. Periodontal inflammation was found to be higher in the test compared with the control group (p < 0.05) and decreased over time in both groups (p < 0.05). Microbiological outcomes showed no intergroup differences (p > 0.05) in prevalence of bacteria, but a decrease in subgingival periodontopathogens from T1 to T2 in the test group (p < 0.05) was observed. Interleukin (IL)-1β levels in GCF at T2 were not different between groups (p > 0.05). In women with PPROM, GCF levels of IL-8 (p < 0.05) and C-reactive protein (p < 0.05) were lower and IL-10 levels higher (p < 0.05) compared with controls. Periodontal inflammation is elevated during pregnancy and seems to be more pronounced in women with PPROM. The findings of the present study revealed an association between periodontal inflammation and PPROM, thus emphasizing the importance of optimizing self-performed oral hygiene in pregnant women.

Comparison of periodontal inflammatory conditions among habitual gutka chewers and betel quid chewers.

The aim was to compare the periodontal inflammatory conditions among habitual gutka chewers and betel quid (BQ) chewers. Forty-five gutka chewers, 45 BQ chewers and 50 non-chewers (controls) were included. Demographic data regarding age, gender, duration, and frequency of gutka- and BQ-chewing habits and gingival bleeding were collected using a questionnaire. Clinical periodontal parameters [plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (AL)] were recorded. Marginal bone loss (MBL) was measured on digital panoramic radiographs. Group differences in periodontal inflammatory parameters were tested using univariate and multivariable analyses (α < 5%). Periodontal inflammatory parameters [PI, BOP, PD (4-6 and >6 mm), clinical AL and MBL] were significantly high in gutka and BQ chewers than controls. There was no significant difference in periodontal inflammatory parameters among gutka and BQ chewers. The odds for gingival bleeding were six times and 13 times higher in gutka and BQ chewers, respectively, compared to controls. Comparison of gutka and BQ chewers did not significantly increase the odds of gingival bleeding. Periodontal inflammatory conditions were comparable among habitual gutka and BQ chewers; which suggests that gutka chewers and BQ chewers are equally susceptible to periodontal disease.

Effect of Glycemic Control on Self‐Perceived Oral Health, Periodontal Parameters, and Alveolar Bone Loss Among Patients With Prediabetes

The effect of glycemic control on severity of periodontal inflammatory parameters in patients with prediabetes is unknown. The aim of the present study is to assess the effects of glycemic control on self-perceived oral health, periodontal parameters, and marginal bone loss (MBL) in patients with prediabetes. A total of 303 individuals were included. Hemoglobin A1c (HbA1c) and fasting blood glucose levels (FBGLs) were recorded. Participants were divided into three groups: 1) group A: 75 patients with prediabetes (FBGLs = 100 to 125 mg/dL [HbA1c ≥5%]); 2) group B: 78 individuals previously considered prediabetic but having FBGLs <100 mg/dL (HbA1c <5%) resulting from dietary control; and 3) control group: 150 medically healthy individuals. Self-perceived oral health, socioeconomic status, and education status were determined using a questionnaire. Plaque index (PI), bleeding on probing (BOP), probing depth (PD), and clinical attachment loss (AL) were recorded. Premolar and molar MBLs were measured on panoramic radiographs. Periodontal parameters (PI, BOP, PD, and AL) (P <0.01) and MBL (P <0.01) were worse among individuals in group A than those in group B. Self-perceived gingival bleeding (P <0.001), pain on chewing (P <0.001), dry mouth (P <0.001), and oral burning sensations (P <0.05) were worse among patients in group A than those in group B. There was no difference in periodontal parameters, MBL, and self-perceived oral symptoms among patients with prediabetes in group B and healthy controls. Self-perceived oral health, severity of periodontal parameters, and MBL are worse in patients with prediabetes than controls. Glycemic control significantly reduces the severity of these parameters as well as the state of prediabetes in affected individuals.
