Effect of nonsurgical periodontal therapy on salivary visfatin and serum lipid levels in obese patients with chronic periodontitis

Do all individuals benefit equally from non-surgical periodontal therapy? Secondary analyses of systematic review data.

This study aimed to assess the variability and treatment effect heterogeneity in response to non-surgical periodontal therapy (NSPT). Data from randomized controlled trials included in two recent systematic reviews on the effect of NSPT on mean clinical attachment loss (CAL), mean probing pocket depth (PPD), percentage of sites with bleeding on probing (%BOP), PPD ≤3 mm (%PD ≤3 mm), and C-reactive protein levels (CRP) at 3-12-month follow-up among adults with systemic diseases or conditions were used. In these trials, the control arms received no treatment, hygiene advice, or supragingival scaling. The Bayesian meta-regression models were utilized to assess the variability ratios between NSPT and control groups. Data from 36 trials on mean PPD, 32 trials on mean CAL, eight trials on %PD ≤3 mm, 31 trials on %BOP and 19 trials on CRP were used. Variability in mean CAL and CRP was approximately 10% higher in the NSPT arms than in the control arms, hinting that there may be room for treatment effect heterogeneity. Instead, variability in mean PPD, %BOP, and %PD ≤3 mm was lower in the NSPT arms than in the control arms. Potential treatment effect heterogeneity in response to NSPT was observed for CRP and mean CAL. However, substantial measurement error in CAL and natural variation in CRP may contribute to these findings. Conversely, treatment effect heterogeneity appears less pronounced for mean PPD, %BOP, and %PD ≤3 mm, potentially due to greater treatment effects in patients with more severe periodontitis and reduced measurement error in these parameters.

AMMP-8 POCT vs. Other Potential Biomarkers in Chair-Side Diagnostics and Treatment Monitoring of Severe Periodontitis.

This study aimed to compare several potential mouthrinse biomarkers for periodontitis including active matrix-metalloproteinase-8 (aMMP-8), total MMP-8, and other inflammatory biomarkers in diagnosing and monitoring the effects of nonsurgical periodontal therapy. Thirteen patients with stage III/IV periodontitis were recruited, along with thirteen periodontally and systemically healthy controls. These 13 patients were representative of the number of outpatients visiting any dentist in a single day. Full-mouth clinical periodontal parameters and biomarkers (the aMMP-8 point-of-care-test [POCT], total MMP-8, tissue inhibitor of MMPs (TIMP)-1, the aMMP-8 RFU activity assay, Myeloperoxidase, PMN elastase, calprotectin, and interleukin-6) were recorded at baseline and after nonsurgical therapy at 6 weeks. The aMMP-8 POCT was the most efficient and precise discriminator, with a cut-off of 20 ng/mL found to be optimal. Myeloperoxidase, MMP-8's oxidative activator, was also efficient. Following closely in precision was the aMMP-8 RFU activity assay and PMN elastase. In contrast, the total MMP-8 assay and the other biomarkers were less efficient and precise in distinguishing patients with periodontitis from healthy controls. aMMP-8, MPO, and PMN elastase may form a proteolytic and pro-oxidative tissue destruction cascade in periodontitis, potentially representing a therapeutic target. The aMMP-8 chair-side test with a cut-off of 20 ng/mL was the most efficient and precise discriminator between periodontal health and disease. The aMMP-8 POC test can be effectively used by dental professionals in their dental practices in online and real-time diagnoses as well as in monitoring periodontal disease and educating and encouraging good oral practices among patients.

Effect of nonsurgical periodontal therapy with additional photodynamic therapy on the level of MMP-9 and TIMP-1 in GCF in chronic periodontitis patients-a preliminary pilot study

PurposeMatrix metalloproteinases (MMPs) catalyze degradation of extracellular matrix proteins. The activity of MMPs is controlled by tissue inhibitors of metalloproteinases (TIMPs). An imbalance in the MMP-9/TIMP-1 ratio has been linked with chronic periodontitis (CP). Photodynamic therapy (PDT) uses visible light, photosensitizer and oxygen to eradicate pathogens. The aim of the study was to evaluate the presence of MMP-9 and TIMP-1 in gingival crevicular fluid (GCF) in chronic periodontitis patients before and after nonsurgical periodontal therapy with additional PDT. MethodsNineteen patients, each with CP, were included in the study. After periodontal examination one site with a probing depth (PD) ​≥ ​4 ​mm was selected. The patients received scaling and root planing (SRP) with additional PDT by means of HELBO® diode minilaser. Prior to treatment, and after 3 and 6 months, the following parameters were estimated from the same site: PD, gingival recession (GR), clinical attachment level (CAL), plaque index (PI), bleeding on probing (BOP) and sulcus fluid flow rate (SFFR). The levels of MMP-9 and TIMP-1 in GCF were determined. ResultsCompared to baseline, the levels of MMP-9 and TIMP-1 did not show statistically significant differences after 3 and 6 months. According to Spearman's rank correlations, MMP-9 was positively correlated with SFFR at all time points. PD, CAL and PI showed a statistically significant decrease compared to baseline (p ​< ​0.001). SFFR decreased but not significantly. ConclusionNonsurgical periodontal therapy in conjunction with PDT was clinically effective but it had no effect on the levels of MMP-9 and TIMP-1 in GCF.

Research progress on the effect of non-surgical periodontal therapy on glycemic control in patients with type 2 diabetes mellitus

Both periodontitis and diabetes are chronic inflammatory diseases, which are widely prevalent in the world. For more than 50 years, the research on the relationship between periodontitis and type 2 diabetes has been actively carried out. The epidemiological correlation between these diseases has been basically identified, but the impact of periodontal therapy on glycaemic control in patients with type 2 diabetes has been controversial for a long time. Glycaemic control is a key issue in the care of people with diabetes. If the positive effect of periodontal therapy on improving glycemic control in diabetic patients compared with no active treatment can be identified, it will help establish periodontal therapy as an effective auxiliary measure for glycaemic control of diabetes patients, and further confirm the relationship between dental health and systemic diseases. Through reviewing the literature, it has been basically determined that the glycaemic control of diabetes patients can be improved within 6 months after the commencement of non-surgical periodontal therapy. In addition, the guidelines of diabetes and suggestions involved periodontal therapy that are constantly put forward by various countries and health organizations at all levels,while in China with extremely heavy in the burden of diabetes, also should propose the guidelines and suggestions of diabetes in accordance with China's national conditions. Both periodontitis and diabetes are diseases with special emphasis on prevention. To clarify the relationship between periodontitis and diabetes can give enlightenment in preventing the occurrence and development of the two diseases.

Effect of non-surgical periodontal therapy on salivary and gingival crevicular fluid concentration of visfatin in periodontal health and disease

Background and objectiveVisfatin, a pleotropic mediator mostly produced by visceral fat, is crucial in controlling the immunological and defensive systems. It serves the roles of a cytokine, an enzyme involved in energy metabolism, and a growth factor. The objective of the present study was to assess the impact of non-surgical periodontal therapy (scaling and root planing) on visfatin concentrations in saliva and gingival crevicular fluid in individuals with Periodontitis (stage-II grade-A) Materials and methods54 individuals were divided into Group A (Periodontally Healthy) and Group B1(Periodontitis baseline) based on periodontal parameters including plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and radiographic parameters. After NSPT (SRP), Group B1 patients were recalled after 4 weeks, constituting Group B2 (post NSPT group B1). At baseline and 4 weeks after non-surgical periodontal therapy (SRP), all clinical parameters, salivary and GCF samples were recorded. An ELISA kit was used to measure the levels of visfatin. Using the paired t-test, unpaired t-test, and Pearson's correlation coefficient, data were analysed using SPSS 15. ResultsAfter non-surgical periodontal treatment (SRP), the mean salivary and gingival crevicular fluid concentration of visfatin considerably decreased to a level comparable to periodontal health. In all groups, GCF visfatin concentration was higher than salivary concentration of visfatin. In periodontitis patients, visfatin concentration in GCF was 1.5 times higher than in saliva. ConclusionThe results of this investigation suggest a direct correlation between salivary and gingival crevicular fluid visfatin concentration and periodontal tissue inflammation and disease activity.

Effect of initial periodontal therapy on metallothionein levels in smokers and non-smokers with periodontitis.

The aim of this study was to determine the effect of non-surgical periodontal therapy (NSPT) on mRNA expression of metallothionein (MT) and its levels in serum, saliva and gingival crevicular fluid (GCF) of smokers (S) and non-smokers (NS) with periodontitis (P).A total of 100 participants were included: 48 periodontally healthy (PH) subjects (24 S [PH + S] and 24 NS [PH + NS]) and 52 patients with P (27 S [P + S] and 25 NS [P + NS]). Clinical parameters were recorded, and biofluids (serum, saliva and GCF) and gingival tissue samples were obtained at baseline in all groups and 3months after NSPT in P groups. MT levels in biofluids were determined by ELISA. In gingival tissues, MT-mRNA expression was quantified using real-time PCR. mRNA expression of MT and its levels in biofluids were significantly higher in P + S compared to other groups, and the differences between P + NS and PH + S were non-significant. A significant decrease was observed for MT levels in biofluids, and MT-mRNA expression in periodontitis patients after NSPT. In conclusion, smoking and periodontitis are associated with higher MT expression which decreases after NSPT. MT as an oxidative stress biomarker and its therapeutic role in periodontitis should be investigated in future studies.Clinical trial registration: The study was prospectively registered at Clinical Trials Registry-India (ctri.nic.in) as CTRI/2018/08/015427 on August 23, 2018.

Effect of Periodontal Therapy on Rheumatoid Disease Activity in Patients on Anti-Rheumatoid Drugs - A Prospective Study.

The aim of this clinical trial rheumatoid arthritis-chronic periodontitis (RA-CP) is to assess the effect of non-surgical periodontal therapy in RA patients. Sixty RA patients taking disease-modifying anti-rheumatoid drugs (DMARD) with CP were selected from the Institute of Rheumatology, Madras Medical College, randomised into the intervention group (IG) and control group (CG). IG received non-surgical periodontal therapy after the screening visit, but CG did not receive treatment until the 3 months study period. Periodontal parameters were recorded at baseline and after 3 months for both groups. Rheumatoid Disease activity (RD activity) was assessed using disease activity score (DAS28), inclusive of tender joints count (TJC), swollen joints count (SJC), visual analog scale (VAS), and erythrocyte sedimentation rate (ESR) for both groups at baseline and after 3 months. At the end of 3 months, IG had significant reduction in RA parameters such as tender joints count (0.0005), swollen joints count (0.0005), ESR (0.003), VAS score (0.0005), and DAS28 values (0.0005) compared to CG. Periodontal parameters at the end of 3 months were also significantly reduced in IG than in CG. Non-surgical periodontal therapy might have reduced the burden of systemic inflammatory markers, thus reducing severity of RA in IG. Reduction in tenderness and swelling of joints in the upper arm might have enabled the patients in IG to perform better oral hygiene maintenance procedures.

Effect of non-surgical periodontal therapy on salivary histone deacetylases expression: A prospective clinical study.

To evaluate the effect of non-surgical periodontal therapy (NSPT) on salivary histone deacetylases (HDACs) gene expression in patients with Stage III-IV periodontitis at baseline and at 3 and 6 months post NSPT treatment. Twenty patients completed the study. Periodontitis (as well as the corresponding staging and grading) was diagnosed according to the 2017 World Workshop Classification. Clinical measures were recorded and whole unstimulated saliva was collected at baseline and at 3 and 6 months after NSPT. The expression of 11 HDACs was determined using reverse-transcription PCR, and the respective changes over time were evaluated. Six months after NSPT, significant improvements in all clinical periodontal parameters were observed, concomitant with significant up-regulation of HDAC2, 4, 6, 8, 9 and 11 expressions. Subgroup analyses of non-responders and responders revealed no significant differences in HDACs mRNA expression between groups at any time point. This prospective clinical study identifiedlongitudinal changes in salivary HDACs expression in response to NSPT, which provides new insights into the epigenetic mechanisms underlying the pathobiology of periodontitis and creates avenues for the discovery of novel biomarkers.

To Evaluate the Association Between Serum Concentration of Vitamin D and Chronic Periodontitis in Non-menopausal Females: A Clinico Biochemical Study.

Periodontal disease's initiation and propagation is through a dysbiosis of the commensal oral microbiota. But recently, through the extraordinary progress, the interrelationship that exists between periodontal disease and systemic health has been unveiled. Through various studies, it has been revealed that vitamin D deficiency may be associated with a greater risk of developing chronic periodontitis and vitamin D supplementation may help to preserve periodontal health. To find a co-relation between 25-hydroxy vitamin D status and the severity of periodontal diseases. To evaluate and compare the effect of non-surgical periodontal therapy alone and in combination with vitamin D supplementation in reducing the severity of periodontal diseases. The present study was conducted on 90 non-menopausal female subjects who divided into 3 groups. Group I comprised of healthy controls. Group II comprised of patients with moderate chronic periodontitis who were assigned to receive only Scaling and root planing (SRP). While group III included patients with moderate chronic periodontitis who were assigned to receive SRP along with Vitamin D supplementation. The periodontal parameters and serum levels of 25- hydroxy vitamin D were recorded for all the participants at baseline. Group II and group III participants were reassessed at an interval of 3 months post-treatment. The results indicated that vitamin D deficiency affected periodontal health negatively. Statistically highly significant improvement was observed in Group III as compared to group II, signifying the efficacy of vitamin D supplementation adjunctive to SRP. Regular evaluation of Vitamin D levels and supplementation to treat the deficiency may have potential periodontal health benefits.

Effect of non-surgical periodontal therapy on CD14 + CD16+ monocyte counts in peripheral blood samples: a clinical interventional study

Monocytes and their macrophage progeny are thought to be involved in tissue and alveolar bone destruction in periodontal disease. It has been documented that the proportion of (CD14 + CD16+) non-classical monocytes in the blood are elevated in chronic periodontitis;A total of 20 chronic generalized periodontitis patients who were otherwise healthy, were recruited for this study. At baseline and 3 weeks after non-surgical periodontal treatment, peripheral blood was obtained to assess the levels of C-reactive protein (CRP) and the proportion of monocyte subsets. Monocyte subsets were assessed using flow cytometry;The mean percentage of CD14 + CD16+ non-classical monocytes in the peripheral blood sample at baseline was 13.95 + 2.09, that reduced to 8.94 + 1.23 3 weeks after non-surgical treatment. A distinct significant reduction in the percentage of non-classical monocytes and a concomitant increase in classical monocytes were observed following periodontal treatment compared to baseline. There was a significant reduction in the all the periodontal parameters and CRP levels 3 weeks post non-surgical periodontal treatment. A positive correlation between CRP and percentage of non-classical monocytes was also observed; Periodontal treatment potentially modulates the host response effectively.

Effect of Non-Surgical Periodontal Therapy on Chronic Kidney Disease Patients: A Systematic Review

The effect of non-surgical periodontal therapy on HbA1c levels: A systematic review

Objective: The purpose of the present article is to summarize the evidence present in systematic regarding the non-surgical periodontal therapy effects on HbA1c levels.&#x0D; Methods: Our study considered the consultation of the bibliographic databases "Medical Systematic Analysis and Retrieval System". The research was carried out by using the keywords: "Diabetes mellitus" AND "Periodontal disease" AND "Scaling and root planing" AND "Non-surgical periodontal treatment" AND "Glycosylated hemoglobin".&#x0D; Our research resulted in 18 articles published between 1995 and 2018.&#x0D; Results: All studies have shown that periodontal indices have improved after non-surgical periodontal therapy, while the effects on metabolic control are controversial. Some authors find no influence on metabolic variables, others report an improvement. Some studies have used both topical and systemic antibiotics in combination with causal periodontal therapy, observing an improvement in metabolic compensation.&#x0D; Conclusion: The approach to diabetic patient with periodontitis must be multidisciplinary with close collaboration between periodontists, dental hygienists and endocrinologists.

Effect of non-surgical periodontal treatment on cytokines/adipocytokines levels among periodontitis patients with or without obesity: a systematic review and meta-analysis

BackgroundThe objective of this systematic review and meta-analysis was to evaluate the effects of non-surgical periodontal therapy (NSPT) on inflammatory-related cytokines/adipocytokines in periodontitis patients with or without obesity.MethodsWe followed the preferred reporting items for systematic reviews and meta-analyses statement and registered the study (CRD42022375331) in the Prospective International Register of Systematic Reviews. We screened randomized-controlled trials and controlled clinical trials from six databases up to December 2022. Quality assessment was performed with RoB-2 and ROBINS-I tools for randomized trials and non-randomized trials, respectively. Meta-analysis was carried out using a random-effect model.ResultsWe included seventeen references in the systematic analysis, and sixteen in the meta-analysis. Baseline results of pro-inflammatory biomarkers, including serum interleukin (IL)-6, serum and gingival crevicular fluid (GCF), tumor necrosis factor (TNF)-a, serum C-reactive protein (CRP)/hs-CRP, and serum and GCF resistin, were higher in obesity subjects than in normal weight subjects. The effect of NSPT with respect to levels of cytokines/adipocytokines, including IL-6, TNF-a, CRP/hs-CRP, resistin, adiponectin, leptin and retinol binding protein 4 (RBP4), were then analyzed in the systematic and meta-analysis. After three months of NSPT, serum (MD = -0.54, CI = -0.62 – -0.46), and GCF (MD = -2.70, CI = -4.77 – -0.63) levels of IL-6, along with the serum RBP4 (MD = -0.39, CI = -0.68–0.10) decreased in periodontitis individuals with obesity. NSPT also improved GCF adiponectin levels after three months (MD = 2.37, CI = 0.29 – 4.45) in periodontitis individuals without obesity.ConclusionsObese status altered the baseline levels of cytokines/adipocytokines (serum IL-6, serum and GCF TNF-a, serum CRP/hs-CRP, and serum and GCF resistin). Then NSPT can shift the levels of specific pro-inflammatory mediators and anti-inflammatory mediators in biological fluids, both in obesity and non-obesity individuals. NSPT can reduce serum and GCF IL-6 levels together with serum RBP4 level in individuals with obesity after 3 months, besides, there is no sufficient evidence to prove that obese patients have a statistically significant decrease in the levels of other cytokines compared to patients with normal weight. NSPT can also increase GCF adiponectin level in normal weight individuals after 3 months. Our findings imply the potential ideal follow-up intervals and sensitive biomarkers for clinical bioanalysis in personalized decision-making of effect of NSPT due to patients’ BMI value.

Effect of nonsurgical periodontal therapy on interleukin-35 level in gingival crevicular fluid

ABSTRACT Background: Clinical attachment level (CAL), alveolar bone loss, and periodontal pockets constitute the major signs of periodontitis. The interaction between the host and the bacteria that forms a biofilm on the tooth surface is one of the major etiologies of periodontal disorders. Aim: The aim of this study was to assess interleukin-35 (IL-35) levels pre and post nonsurgical periodontal therapy (NSPT) in healthy individuals and gingivitis and periodontitis patients. Materials and Methods: IL-35 level in gingival crevicular fluid (GCF) and clinical parameters were assessed in 60 individuals. Biochemical analysis was done by enzyme-linked immunosorbent assay. Individuals in Group I were in good health; those in Groups II and III had gingivitis and periodontitis, respectively. Study individuals were evaluated at baseline and 3 months after NSPT. Results: Group III differed from Group II in that it had higher CAL (7.60), plaque index (2.8929), and periodontal probing depth (5.8500 mm) values, as well as lower papillary bleeding index (2.1170) and gingival index (2.1085) values. The concentrations of IL-35 in GCF varied among the groups, with Group III having the lowest concentrations and rising gradually to Groups II and I. In addition, from baseline to 3 months, the IL-35 levels in GCF significantly decreased in both Groups II and III. The results show that Groups II and III have lower GCF levels of IL-35 than Group I, suggesting that IL-35 is a major factor in the development of periodontal diseases. Conclusion: Group I had considerably greater GCF IL-35 values than Group II and III both before and after NSPT.

Effect of Non-Surgical Periodontal Therapy on Systemic Inflammatory Markers, Glycemic Status and Levels of Proteinuria in Type 2 Diabetic and Non-Diabetic Patients With Chronic Periodontitis.

The present study aimed to evaluate the effect of non-surgical periodontal therapy (NSPT) on systemic inflammatory markers, glycemic status, and levels of proteinuria in Type 2 diabetic and non-diabetic individuals with chronic periodontitis. A total of 120 patients, categorized into three groups of 40 each, were included in this randomized observational study. Group 1 comprised patients with chronic periodontitis; Group 2 had chronic periodontitis with controlled diabetes; and Group 3 represented patients with chronic periodontitis with uncontrolled diabetes based on fasting blood sugar (FBS) and glycated hemoglobin (HbA1c) levels. Periodontal clinical parameters like plaque index, gingival index, bleeding on probing, pocket depth, and clinical attachment levels were evaluated. Blood samples and urine samples were collected and assessed for the levels of FBS, HbA1c, total protein, albumin, globulin, and proteinuria. All parameters recorded at baseline and three months after non-surgical periodontal therapy were analyzed for statistical significance at p <.05 using SPSS Inc. Released 2007. SPSS for Windows, Version 16.0. Chicago, SPSS Inc. A significant reduction in the periodontal clinical parameters within the groups, except for the clinical attachment level in Group 1 patients (p = 0.05), was observed. Glycemic status revealed a significant reduction after non-surgical periodontal therapy (p < 0.001), and on intragroup comparison, the total protein, albumin, globulin, and microprotein blood and urine levels showed significance among the evaluated groups (p < 0.001). Non-surgical periodontal treatment can effectively improve the periodontal and circulating inflammatory status. Results of our study showed improved glycemic control and a reduction in systemic inflammatory markers and proteinuria after performing non-surgical periodontal treatment in patients with type 2 diabetes.

Effects of Nonsurgical Periodontal Therapy on Glycemic Control in Diabetic Patients under Systemic Administration of Antidiabetic Ayurvedic Drug.

This study aimed to monitor the metabolic response of nonsurgical periodontal therapy in type-2 diabetic patients with chronic periodontitis under systemic administration of antidiabetic ayurvedic drug. About 90 newly diagnosed mild-to-moderate forms of type-2 diabetes mellitus (DM) subjects with generalized chronic periodontitis were selected according to the inclusion and exclusion criteria and were randomly divided into group A and group B with 45 patients in each group. Clinical parameters, including plaque index, probing pocket depth, clinical attachment level, and glycemic status, were assessed at baseline. Following initial periodontal clinical examination, the drug Nishamalaki (NA) 2 gm twice daily for 3 months was prescribed after food by an Ayurvedic physician to all the patients enrolled in group A and group B, and scaling and root planing were completed only for group B patients. Patients were recalled for review, and all the parameters were reassessed at the end of the 1st, 2nd, and 3rd months following interventions. Regarding clinical and metabolic parameters at baseline, no statistically significant differences were displayed between the two groups. However, at the 3-months follow-up period, the patients in group B demonstrated significantly better clinical and metabolic outcomes than patients in group A. Periodontal therapy improved glycemic control in patients with type-2 DM in both groups; however, the reduction in FBS values reached statistical significance only in the group receiving scaling and root planing alone. Nonsurgical periodontal therapy may have a beneficial effect on the periodontal clinical and glycemic levels in type-2 diabetic patients with chronic periodontitis.

Effect of Non-Surgical Periodontal Therapy on Renal Function Among Pre-Dialysis Chronic Kidney Disease Patients

Background: Association between chronic kidney disease (CKD) and periodontitis has been established. The aim of this study was to determine the effect of non-surgical periodontal therapy (NSPT) on renal function among pre-dialysis CKD patients. Methods: This is an intervention study involving 120 CKD participants. 60 CKD participants constituted the intervention group while 60 CKD participants constituted the control group. Blood samples were collected from all participants at baseline and after 3 months for the measurement of high sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), and serum creatinine for the estimation of glomerular filtration rate (eGFR). Periodontal clinical examination was performed in all participants at six sites per tooth by the researcher for the measurement of Probing Pocket Depth (PPD) and Clinical Attachment Loss (CAL). The intervention group received NSPT (scaling and root planning) and oral hygiene motivation while the control group received only oral hygiene motivation only. Re-evaluation was done after 3 months. Results: In this study, three months post NSPT, PPD reduced from 5.44mm to 3.17mm (P &lt; 0.01) and CAL from 6.29mm to 4.29mm (P &lt; 0.01) in the intervention group. There was also a statistically significant reduction in the mean values of hsCRP and IL-6 at 3 months post NSPT in the intervention group (p&lt;0.01). However, there was no reduction observed in the control group (p=0.59 and 0.66) respectively. Estimated GFR (eGFR) for the intervention group improved from 40.55 mL/min/1.73m2 to 43.22 mL/min/1.73m2 three months post NSPT (P &lt; 0.01). Conclusion: This study demonstrates the potential beneficial effects of NSPT on renal function among pre-dialysis CKD participants as estimated by improvement in eGFR.

Calprotectin and periostin levels in periodontitis patients with coronary artery disease.

The aim of the study was to assess the effect of non-surgical periodontal therapy (NSPT) on periodontal and cardiac parameters as well as on the expression of calprotectin and periostin levels in periodontitis patients with and without coronary artery disease (CAD). Ninety subjects were categorised into three groups: Group H: periodontally and systemically healthy subjects, Group P: stage III grade B periodontitis subjects with no associated systemic diseases and Group P + CAD: stage III grade B periodontitis subjects diagnosed with CAD. Demographic, periodontal and cardiac parameters were recorded at baseline (0 day) and on the 180th day after NSPT. Gingival crevicular fluid was collected from all participants at baseline (0 day) and after the 180th day. Calprotectin and periostin expression were reassessed. A significant increase in the levels of calprotectin (34.05 ± 11.72) was seen at baseline in the P + CAD group, whereas on the contrary, a decreased periostin (1.59 ± 0.41) was also noted at baseline. The study also showed a significant improvement in periodontal and cardiac parameters on the 180th day following NSPT. Detection of calprotectin and periostin expression in GCF samples could represent a link to the association of periodontitis and CAD.

Effect of nonsurgical periodontal therapy on serum lipid profile levels – A comparative study

ABSTRACT Background: Regarding the high prevalence of hyperlipidemia, which is one of the major risk factors of cardiovascular disease and periodontitis, which is a known bacterial infection, classified as local chronic inflammation. Aim: The present study aimed to assess and correlate periodontal parameters with serum lipid profile levels at baseline and 45 days after nonsurgical periodontal therapy (NSPT). Results: It showed a statistically significant decrease in total cholesterol, low-density lipoproteins (LDL), very LDL and triglycerides, and a significant rise in high-density lipoproteins correlated with a significant reduction in the plaque index and gingival index, from baseline to 45 days after NSPT. Conclusion: It can be concluded that elevated serum lipids have a dysregulatory effect on the tissue response, which, in turn, affects the extent and progression of periodontitis, and in the presence of periodontitis, lipid metabolism will be affected through the systemic effect of cytokines.
