Nuclear imaging to visualize periodontal inflammation: Findings of a randomized controlled trial.

To investigate non-surgical periodontal therapy by 18F-fluorodeoxyglucose (2-[18 F]FDG) uptake using positron emission tomography (PET) integrated with computed tomography (CT). Eighty-five patients with peripheral artery disease and severe periodontitis-randomized into three groups receiving therapy with (PT1; n = 29) or without (PT2; n = 28) systemic antibiotics or no treatment (controls: n = 28)-underwent nuclear imaging at baseline and at 3 months. Clinical inflammation (periodontal inflamed surface area; PISA) did not significantly differ across the groups at baseline (p = 0.395) but was significantly reduced at 3 months (p < 0.001), and significantly more so in the PT1/PT2 groups than in the control group (p < 0.001/=0.025) and in the PT1 than in the P2 group (p = 0.001). Radiotracer uptake was measured in both jaws using maximum and mean 'standardized uptake values' (SUVmax , SUVmean ) and 'target-to-background ratios' (TBRmax , TBRmean ). At 3 months, reductions were relatively small in absolute numbers and fell short of revealing correlations with PISA or significant differences across the groups. Still, they were very consistent in both treatment groups, whereas reductions were not consistently seen in the control group. 2-[18 F]FDG PET/CT scans did reflect the clinical effects of periodontal treatment very consistently but, for reasons yet to be clarified, less closely than expected.

Importance of Metalloproteinase 8 (MMP-8) in the Diagnosis of Periodontitis.

Periodontitis is a complex condition. Left untreated, it leads to tooth loss and the need for prosthetic treatment. The incidence of periodontitis is steadily increasing, so new methods are being sought to aid in the diagnosis of the disease. Among the methods postulated is the determination of concentrations of bioactive compounds which include extracellular matrix metalloproteinases (MMPs). These enzymes are present in various structural elements of the stomatognathic system. The most promising enzyme of this group appears to be metalloproteinase 8 (MMP-8). MMP-8 assays are performed in gingival fluid or saliva, and MMP-8 levels have been shown to be higher in patients with periodontitis compared to healthy subjects and correlated with some clinical parameters of the condition and the severity of the disease. In addition, the preliminary usefulness of this enzyme in evaluating the effectiveness of periodontal treatment and doxycycline therapy has been demonstrated. Determination of the active form of MMP-8 (aMMP-8) in oral rinse fluid using off-the-shelf assays shows the highest potential. Despite reports about aMMP-8 and promising data on the role of MMP-8 in periodontal diagnosis, a clear determination of the usefulness of this enzyme requires further research.

Effect of Periodontitis and Periodontal Therapy on Oral and Gut Microbiota

Mounting evidence indicates that periodontitis-related oral bacteria may contribute to gut microbial dysbiosis. This clinical study aimed to explore the oral–gut microbial signatures associated with periodontitis and to longitudinally evaluate the effect of periodontal treatment on the oral and gut microbial composition. Stool and saliva samples from generalized stage III/IV periodontitis patients (n = 47) were collected and analyzed by 16S ribosomal RNA gene amplicon sequencing, before and 3 mo after steps I to II of periodontal therapy. Periodontally healthy matched subjects (n = 47) were used as controls. Principal component analysis was carried out to identify oral–gut microbial profiles between periodontitis patients at baseline and healthy subjects; periodontitis samples were longitudinally compared before and after treatment. β-Diversity of gut microbial profiles of periodontitis patients before treatment significantly differed from healthy controls (P < 0.001). Periodontal therapy was associated with a significant change in gut microbiota (P < 0.001), with post-treatment microbial profiles similar to healthy volunteers. A higher abundance of Bacteroides, Faecalibacterium, Fusobacterium, and Lachnospiraceae was noted in fecal samples of periodontitis patients at baseline compared to healthy controls. In contrast, Lactobacillus was the only genus more abundant in the latter. Additionally, periodontal therapy led to a parallel reduction in the salivary carriage of periodontal pathobionts, as well as gut Bacteroides, Lachnoclostridium, Lachnospiraceae, Oscillospiraceae, and Ruminococcaceae, to levels similar to healthy controls. Collectively, discriminating oral–gut microbial signatures of periodontitis were found. Periodontal treatment both mitigated oral dysbiosis and altered gut microbial composition, signifying potential broader implications for gastrointestinal health and disease.

Nitrate reduction capacity of the oral microbiota is impaired in periodontitis: potential implications for systemic nitric oxide availability

The reduction of nitrate to nitrite by the oral microbiota has been proposed to be important for oral health and results in nitric oxide formation that can improve cardiometabolic conditions. Studies of bacterial composition in subgingival plaque suggest that nitrate-reducing bacteria are associated with periodontal health, but the impact of periodontitis on nitrate-reducing capacity (NRC) and, therefore, nitric oxide availability has not been evaluated. The current study aimed to evaluate how periodontitis affects the NRC of the oral microbiota. First, 16S rRNA sequencing data from five different countries were analyzed, revealing that nitrate-reducing bacteria were significantly lower in subgingival plaque of periodontitis patients compared with healthy individuals (P < 0.05 in all five datasets with n = 20–82 samples per dataset). Secondly, subgingival plaque, saliva, and plasma samples were obtained from 42 periodontitis patients before and after periodontal treatment. The oral NRC was determined in vitro by incubating saliva with 8 mmol/L nitrate (a concentration found in saliva after nitrate-rich vegetable intake) and compared with the NRC of 15 healthy individuals. Salivary NRC was found to be diminished in periodontal patients before treatment (P < 0.05) but recovered to healthy levels 90 days post-treatment. Additionally, the subgingival levels of nitrate-reducing bacteria increased after treatment and correlated negatively with periodontitis-associated bacteria (P < 0.01). No significant effect of periodontal treatment on the baseline saliva and plasma nitrate and nitrite levels was found, indicating that differences in the NRC may only be revealed after nitrate intake. Our results suggest that an impaired NRC in periodontitis could limit dietary nitrate-derived nitric oxide levels, and the effect on systemic health should be explored in future studies.

Periostin in the relation between periodontal disease and atherosclerotic coronary artery disease: A pilot randomized clinical study.

The aim of this study was to analyze the effects of periodontal treatment on markers of atherosclerotic coronary artery disease and circulating levels of periostin. Periostin is necessary for periodontal stability, but it is highly present in atherosclerotic plaques. Treatment of periodontal disease, with low levels of local periostin, is thought to reduce systemic levels of periostin. Thus, this may contribute to cardiovascular health. A pilot randomized controlled clinical trial was designed to include patients with severe periodontal disease and history of atherosclerotic coronary artery disease. Samples of gingival crevicular fluid (GCF) and serum were collected before and after periodontal treatment by periodontal surgery or non-surgical therapy. The levels of several markers of inflammation and cardiovascular damage were evaluated including CRP, IFN-γ, IL-1ß, IL-10, MIP-1α, periostin, and TNF-α in GCF and CRP, Fibrinogen, IFN-γ, IL-1ß, IL-6, IL-10, L-Selectin, MIP-1α, Periostin, TNF-α, and vWF in serum. A total of 22 patients with an average of 56 years old were recruited for participating in this study. Twenty of them were male. Most of them (82%) had suffered an acute myocardial event and underwent surgery for placing 1, 2, or 3 stents in the coronary arteries more than 6 months ago but less than 1 year. The treatment of periodontal disease resulted in an overall improvement of all periodontal parameters. Regarding the evaluation of GCF and serum, a significant increase of periostin in the GCF was observed after periodontal surgery. In contrast, although other markers in GCF and serum improved, no significant correlations were found. Treatment of periodontal disease through periodontal surgery induces a local and transient increase in the levels of periostin in the gingival crevicular fluid. The effects on systemic markers of inflammation and cardiovascular function have not been confirmed.

Effect of Periodontal Treatment on Reducing Chronic Inflammation in Systemically Healthy Patients With Periodontal Disease

BackgroundWe determined the effects and an accurate marker of periodontal treatment on serum interleukin (IL)-6 and high-sensitivity C-reactive protein (HsCRP) levels in systemically healthy individuals with periodontal disease. MethodsThis multicenter study included systemically healthy individuals with periodontal disease who received initial periodontal treatment and had no periodontal treatment history. Periodontal parameters, including periodontal inflamed surface area, masticatory efficiency, and periodontal disease classification; serum IL-6 and HsCRP levels; and serum immunoglobulin (Ig)G titers against periodontal pathogens were evaluated at baseline and after treatment. Subjects were classified as low or high responders (group) based on periodontal inflamed surface area changes. ResultsThere were 153 participants. Only periodontal inflamed surface area changes were markedly different between low and high responders. Periodontal treatment (time point) decreased both serum IL-6 and HsCRP levels. The interaction between group and time point was remarkable only for serum IL-6 levels. Changes in serum immunoglobulin (Ig)G titers against periodontal pathogens were not associated with IL-6 changes in high responders. We analyzed the indirect effect of serum anti-Porphyromonas gingivalis type 2 IgG titer changes using mediation analysis and found no significance. However, the direct effect of group (low or high responder) on IL-6 changes was considerable. ConclusionsPeriodontal treatment effectively decreased serum IL-6 levels, independent of periodontal pathogen infection, in systemically healthy individuals with periodontal disease.

The potential positive effect of periodontal treatment on brain function activity using functional magnetic resonance imaging analysis

Background/purposeThere are reports on the relationship between periodontal treatment and the whole body. The purpose of the present study was to investigate the effect of periodontal initial treatment on brain function activity by improving periodontal tissue and the occlusal status of subjects with periodontitis. Materials and methodsThe subjects were 13 patients with periodontitis. Following the patient's informed written consent, the periodontal initial treatment provided to the patient included tooth brushing instruction, scaling and root planning, however, occlusal adjustment was not performed at this stage. Periodontal examination, occlusal force examination and fMRI results were also evaluated at the initial and the reevaluation examinations. ResultsAfter the periodontal initial treatment had been performed, periodontal tissue had significantly improved. In addition, cerebral blood flow in the insula and primary motor cortex was also improved, as confirmed by fMRI. ConclusionThis result suggests that the periodontal ligament has recovered and the periodontal ligament neuron have been further subjected to clenching in the insula.

Growth differentiation factor-15 and circulating biomarkers as predictors of periodontal treatment effects in patients with periodontitis: a randomized-controlled clinical trial

BackgroundDuring the last decades, in patients with periodontitis, periodontal treatment has been shown to reduce the potential release of local and systemic biomarkers linked to an early risk of systemic inflammatory disorders. This study evaluated the efficacy of non-surgical-periodontal treatment (NSPT) on growth differentiation factor 15 (GDF-15) and related circulating biomarkers such as glutathione peroxidase 1 (GPx-1), c-reactive protein (hs-CRP), and surfactant protein D (SP-D) in periodontal patients and explored whether subjects who had high GDF-15 levels at baseline showed increased clinical benefits following NSPT at 6-months follow-up.MethodsFor this two-arm, parallel randomized clinical trial, patients with periodontitis were randomly allocated to receive quadrant scaling and root-planing (Q-SRP, n = 23, median age 51 years old) or full-mouth disinfection (FMD, n = 23, median age 50 years old) treatment. Clinical and periodontal parameters were recorded in all enrolled patients. The primary outcome was to analyse serum concentrations changes of GDF-15 and of GPx-1, hs-CRP, and SP-D at baseline and at 30, 90, and 180-days follow-up after NSPT through enzyme-linked immunosorbent assay (ELISA) and nephelometric assay techniques.ResultsIn comparison with FMD, patients of the Q-SRP group showed a significant improvement in clinical periodontal parameters (p < 0.05) and a reduction in the mean levels of GDF-15 (p = 0.005), hs-CRP (p < 0.001), and SP-D (p = 0.042) and an increase of GPx-1 (p = 0.025) concentrations after 6 months of treatment. At 6 months of treatment, there was a significant association between several periodontal parameters and the mean concentrations of GDF-15, GPx-1, hs-CRP, and SP-D (p < 0.05 for all parameters). Finally, the ANOVA analysis revealed that, at 6 months after treatment, the Q-SRP treatment significantly impacted the reduction of GDF-15 (p = 0.015), SP-D (p = 0.026) and the upregulation of GPx-1 (p = 0.045).ConclusionThe results evidenced that, after 6 months of treatment, both NSPT protocols improved the periodontal parameters and analyzed biomarkers, but Q-SRP was more efficacious than the FMD approach. Moreover, patients who presented high baseline GDF-15 and SP-D levels benefited more from NSPT at 6-month follow-up.Trial registrationNCT05720481.

Association between periodontitis and cardiovascular health in rheumatoid arthritis patients: Prospective effect of periodontal treatment on cardiovascular risk

Rheumatoid arthritis (RA) patients are more likely to develop cardiovascular disease (CVD), which increases the risk of morbidity and mortality. Periodontitis is known to be associated with CVD, yet its relationship with CVD in RA is limited. To examine the relationship between periodontitis with subclinical atherosclerosis and with long term CVD risk. Examining if periodontitis treatment can be associated with CVD improvement was well thought out. This prospective interventional study included 49 adults with RA. Demographic, clinical and therapeutic data and laboratory markers were assessed. Dental examination for periodontitis was performed. The carotid intima media thickness (CIMT) and Framingham risk score (FRS) were evaluated. Medical treatment was provided to RA patients with periodontitis, and assessments were repeated after 6 months. The mean age of the patients was 46.4 ± 12.4 years, disease duration 10.9 ± 5.4 years and 79.6% were females. 25 (51%) patients had subclinical atherosclerosis, 30 (61.2%) had periodontitis and 25 (51%) had both. RA patients with subclinical atherosclerosis had higher clinical attachment loss (CAL) (3.12 ± 1.45) and higher probing depth (PD) (4.96 ± 1.37) compared to those without (p < 0.001). CAL (β = 0.01, 95 %CI: 0–0.01, p < 0.001), and PD (β = 0.01, 95% CI: 0–0.01; p < 0.001) were independently associated with CIMT. The 30 patients after treatment of periodontitis showed an average improvement in the mean CIMT (0.14 mm, p < 0.001). Periodontitis is associated with subclinical atherosclerosis in RA. Treatment of periodontitis could improve the cardiovascular health in RA patients and prompts physicians to early diagnose and treat periodontitis.

Adverse Pregnancy Outcomes and Maternal Periodontal Disease: An Overview on Meta-Analytic and Methodological Quality.

This umbrella review aims to appraise the methodological quality and strength of evidence on the association between maternal periodontitis and adverse pregnancy outcomes (APOs). PubMed, CENTRAL, Web-of-Science, LILACS, and Clinical Trials were searched until February 2023, without date or language restrictions. Two authors independently screened studies, extracted data, performed the risk-of-bias analysis, and estimated the meta-analytic strengths and validity and the fail-safe number (FSN). A total of 43 SRs were identified, of which 34 conducted meta-analyses. Of the 28 APOs, periodontitis had a strong association with preterm birth (PTB), low birth weight (LBW), and gestational diabetes mellitus (GDM), PTB and LBW showed all levels of strength, and pre-eclampsia showed only suggestive and weak strength. Regarding the consistency of the significant estimates, only 8.7% were likely to change in the future. The impact of periodontal treatment on APOs was examined in 15 SRs, 11 of which conducted meta-analyses. Forty-one meta-analyses were included and showed that periodontal treatment did not have a strong association with APOs, although PTB revealed all levels of strength and LBW showed only suggestive and weak evidence. Strong and highly suggestive evidence from observational studies supports an association of periodontitis with a higher risk of PTB, LBW, GDM, and pre-eclampsia. The effect of periodontal treatment on the prevention of APOs is still uncertain and requires future studies to draw definitive and robust conclusions.

Research efficacy of gaseous ozone therapy as an adjuvant to periodontal treatment on oxidative stress mediators in patients with type 2 diabetes: a randomized clinical trial

BackgroundChronic inflammation and cumulative oxidative stress have been theorized as two common pathways of the interconnection between periodontitis and diabetes. Improvement in oxidizing status has been demonstrated in periodontal patients with diabetes treated with proper non-surgical periodontal treatment. In addition to periodontal treatment, Gaseous ozone therapy has been reported to possess anti-inflammatory properties and the ability to stimulate the endogenous antioxidant defence mechanism. To date, the antioxidant effect of gaseous ozone, in addition with periodontal treatment in diabetic patients, has been examined in only one study. The aim of this study was to determine the efficacy of gaseous ozone therapy as an alternative approach to supporting non-surgical periodontal therapy (NSPT), aimed at improving antioxidant machinery and interfering with ROS production on plasma levels in diabetic individuals diagnosed with moderate or severe periodontitis.MethodsOne hundred and eighty patients with periodontitis and type 2 diabetes mellitus were randomly assigned to receive non-surgical periodontal treatment (NSPT) plus gaseous ozone therapy (A) NSPT alone (B). Clinical and periodontal parameters -Bleeding on probing (BOP), Periodontal pocket depth (PPD), and Clinical attachment Level (CAL)- and plasma levels of oxidant-antioxidant (TOS- TAOS) levels, glutathione (GSH), and malondialdehyde (MDA) were recorded at baseline and at 3- (T1) and at 6-months (T2) after treatment.ResultsBoth treatments were efficacious in reducing clinical parameters. However, there were no significant differences regarding oxidative stress parameters in group A compared to group B.ConclusionsIn the present study, gaseous ozone therapy did not enhance the effect of periodontal treatment in reducing oxidative stress in plasma levels of periodontitis patients with type II diabetes.Trial registrationThe study was registered with ISRCTN1728169 (23/07/2022).

Diabetes and Periodontal Disease

Diabetes and periodontitis are chronic inflammatory diseases and have a bidirectional relationship. Periodontitis is more prevalent and more severe in diabetic persons than in nondiabetic persons, and diabetes plays a crucial role in the pathogenesis of periodontitis. Also, periodontitis has shown elevated risk for hyperglycemia and insulin resistance. Thus, mutual management of the two conditions might be necessary. Periodontal therapy is effective in persons with diabetes and is associated with reduction of HbA1c. The present study reviews the mechanistic link between diabetes and periodontitis and the effects of periodontal treatment and can aid in educational planning to prevent periodontitis of diabetic persons.

Periodontal disease in chronic kidney disease patients: salivomics by Fourier-transform infrared spectroscopy.

It has been reported that 58% of individuals with chronic kidney disease (CKD) have moderate to advanced periodontitis due to alterations of pH and biochemical composition in the saliva. In fact, the composition of this important biofluid may be modulated by systemic disorders. Here we investigate the micro-reflectance Fourier-transform infrared spectroscopy (FTIR) spectra of saliva that CKD patients submitted to periodontal treatment, aiming to identify spectral biomarkers of kidney disease evolution and the effectiveness of periodontal treatment, proposing possible biomarkers of disease evolution. Saliva from 24 CKD patients-stage-5 men, 29 to 64years old-was evaluated in (i)patients starting periodontal treatment; (ii)patients 30days after periodontal treatment; and (iii)patients 90days after periodontal treatment. Our findings indicated that there are statistically relevant changes among the groups after 30 and 90days of periodontal treatment, when considering the overall spectra in the fingerprint region (800-1800cm-1). The key bands presenting good prediction power (area under the receiver operating characteristic curve >0.70) were related to poly (ADP-ribose) polymerase (PARP) conjugated to DNA at 883, 1031, and 1060cm-1 (carbohydrates at 1043 and 1049cm-1) and triglycerides (1461cm-1). Interestingly when analyzing the derivative spectra in the secondary structure region (1590-1700cm-1), we detected over-expression of the β-sheet class of secondary structures in 90days of periodontal treatment, possibly related to over-expression of human B-defensins. Conformational changes in ribose sugar in this region corroborate the interpretation concerning PARP detection. To our knowledge, PARP was detected for the first time in saliva samples of stage-5 CKD patients by FTIR. All observed changes were correctly interpreted in terms of intensive apoptosis and dyslipidemia due to kidney disease progression. Biomarkers due to CKD predominate in saliva, and the relative improvement in the periodontal state did not cause remarkable changes in the spectra of saliva.

Does periodontal treatment improve glycaemic control in periodontitis patients with diabetes mellitus?

The electronic databases Cochrane Oral Health's Trials Register, Cochrane Central Register of Controlled Trials, MEDLINE Ovid, Embase Ovid, CINAHL EBSCO, LILACS BIREME Virtual Health Library from inception to September 2021, along with trial registers and journals (hand searching) were searched to identify the randomized controlled trials (RCTs). Two reviewers independently identified and selected RCTs of at least three months' duration, comparing the effectiveness of subgingival instrumentation relative to no active intervention or usual care (oral hygiene instruction, education, or supportive interventions, and/or supragingival scaling) in the reduction of glycated haemoglobin (HbA1c) in periodontitis patients with type 1 or 2 diabetes mellitus. Data extraction and risk of bias assessment were performed by two reviewers independently. Data were synthesized quantitatively with meta-analyses using a random-effects model, and pooled outcomes were expressed as mean differences with 95% confidence intervals. In addition, subgroup analysis, heterogeneity assessment, sensitivity analyses, summary of findings, and assessment of the certainty of the evidence were performed. Out of 3109 identified records, 35 RCTs were included for qualitative synthesis, and amongst them, 33 studies were included for meta-analysis. Meta-analyses showed that periodontal treatment with subgingival instrumentation, compared to usual care or no treatment, led to a mean absolute reduction of 0.43% in HbA1c at 3 to 4 months, 0.30% at six months, and 0.50% at 12 months. The certainty of the evidence was assessed to be moderate. The authors concluded that periodontitis treatment by subgingival instrumentation improves glycaemic control in diabetic patients. However, there is insufficient evidence about the effect of periodontal treatment on quality of life or diabetic complications.

Effects of periodontal treatment on the C-reactive protein levels in hemodialysis patients: A systematic review and meta-analysis.

This systematic review provides a summary of the scientific evidence concerning effects of periodontal treatment on the C-reactive protein (CRP) levels in hemodialysis patients. Eight databases were accessed until May 2020 for interventional studies which evaluated CRP levels in hemodialysis patients before and after periodontal treatment. Inclusion criteria were studies involving hemodialysis patients with gingivitis or periodontitis, without restriction of year, language, and publication status. Random effects meta-analysis was performed. The risk of bias in eligible studies was assessed using the Joanna Briggs Institute's Critical Appraisal tools for use in systematic reviews. Certainty of evidence was also evaluated using GRADE approach. The search in the databases resulted in 326 records, from which only seven met the eligibility criteria and therefore were submitted to qualitative evaluation. The meta-analysis revealed that, in general, the reduction in CRP levels had moderate and statistically significant effect size (standardized mean difference [SMD]=0.45; confidence interval [CI] 95%=0.25, 0.65; p<.001). Statistical heterogeneity was low (I2 =0.0%; p=.771). Most studies showed moderate risk of bias. Based on low certainty of evidence, the results suggest that periodontal treatment can significantly contribute to reduce CRP levels among hemodialysis patients. However, more randomized clinical studies, with follow-up longer than 12 months, using standardized diagnostic methods and controlling confounding factors, should be performed to strengthen the evidence.

The association between respiratory diseases and periodontitis: A systematic review and meta-analysis.

To evaluate (1) whether periodontitis has an influence on the prevalence/incidence of respiratory diseases (chronic obstructive pulmonary disease [COPD], asthma, community-acquired pneumonia [CAP], obstructive sleep apnoea [OSA] and COVID-19), and (2) what is the impact of periodontal therapy on the onset or progression of respiratory diseases. An electronic search was performed on Pubmed, Cochrane Library and Scopus databases up to October 2021, to identify studies answering the PECOS and PICOS questions. Seventy-five articles were selected. Meta-analyses identified statistically significant associations of periodontitis with COPD (nstudies = 12, odds ratio [OR]=1.28, 95% confidence interval [CI] [1.16; 1.42], p< .001), and OSA (ns = 6, OR=1.65, 95% CI [1.21; 2.25], p= .001), but not for asthma (ns = 9, OR=1.53, 95% CI [0.82; 2.86], p= .181). For acute conditions, two studies were found for CAP, while for COVID-19, significant associations were found for the need of assisted ventilation (ns = 2, OR=6.24, 95% CI [2.78; 13.99], p< .001) and COVID-related mortality (ns = 3, OR=2.26, 95% CI [1.36, 3.77], p= .002). Only four intervention studies were found, showing positive effects of periodontal treatment on COPD, asthma and CAP. A positive association between periodontitis and COPD, OSA and COVID-19 complications has been found, while there is a lack of intervention studies.

Modifiable risk factors for the development and progression of periodontal tissue diseases

In this review, an analysis of modifiable risk factors for the development and progression of periodontal tissue diseases was carried out. The review highlights the data on the relationship of periodontal infection, tobacco smoking, diabetes mellitus, cardiovascular disease, drug-induced periodontal tissue damage, stress, and obesity with the risk of developing and progression of periodontal tissue diseases. A rather detailed analysis of the mechanisms of pathogenic influence of the microflora of the oral cavity, including in the subgingival plaque, was carried out. The mechanisms of the pathological effect of smoking on the state of periodontal tissues are described. Data on the effect of periodontal treatment on glycemic control in patients with diabetes mellitus are presented. The article emphasizes the importance of the presence of periodontal diseases as a risk factor for cardiovascular and cerebrovascular diseases, describes the mechanisms of the mutual influence of cardiovascular pathology and the inflammatory process in the periodontium. In addition, the article presents the possibilities of the iatrogenic effect of systemic drugs on the state of periodontal tissues. The data on the influence of stress loads on the development of dental diseases are presented. The review article describes in detail the mechanisms of influence of overweight and obesity on the risks of development and progression of periodontal tissue diseases. Based on the results of the scientific research publications presented in the article, it can be stated that not only the dentist, but also doctors of other specialties need to work to change the modifiable risk factors for the development and progression of periodontal diseases.

HUBUNGAN PENYAKIT PERIODONTAL TERHADAP KELAHIRAN PREMATUR DAN BERAT BADAN LAHIR RENDAH – TINJAUAN PUSTAKA

Introduction: Periodontal disease can mediate systemic effects through the action of periodontal pathogenic bacteria and lipopolysaccharide will increase prostaglandin and cytokine production which can trigger preterm birth. Pregnant women with periodontitis have a significantly higher risk for preterm birth with low birth weight &lt;37 weeks of gestation and birth weight &lt;2.500 grams. However, periodontal therapy can significantly reduce the rate of premature low birth weight among women with periodontitis. This literature review aims to assess the relationship between maternal periodontal diseases on preterm and low birth weight. Literature Review: Periodontitis can act as a reservoir of microbes and inflammatory mediators that affect preterm birth. Several studies have revealed that mothers with periodontal pathogens will increase levels of IL-1β, IL-6, TNF-α and PGE2 that are produced locally through systemic circulation and induce acute phase response in the liver which is characterized by increased levels of C-reactive protein that can trigger a risk of low birth weight. Periodontitis can be a risk factor for preterm birth due to the presence of proinflammatory bacteria and cytokines in the bloodstream that can invade the membrane and placenta. The effectiveness of periodontal treatment to prevent preterm birth is influenced by the diagnostic severity of periodontitis, microbial community composition, and the period of treatment during pregnancy. Conclusion: Periodontal disease is an independent risk factor for preterm birth. Plaque control procedures during pregnancy can reduce the occurrence of preterm and low birth weight.

Nonsurgical periodontal treatment improved the type 2 diabetes mellitus status in smokers: A randomized controlled trial

AimType 2 diabetes mellitus (T2D) and periodontal disease have bilateral associations. The effect of periodontal treatment on T2D patients who smoke is scarce. This study aimed to assess the effect of nonsurgical periodontal treatment (NSPT) in periodontitis smokers with T2D for a duration of 6 months of follow-up. Materials and methodsForty moderate to severe periodontitis smokers with T2D were randomly distributed into two different treatment groups: the test group (NSPT including oral hygiene instructions, scaling and root planing; and 0.05% Chlorhexidine mouthrinse) and the control group (treatment including oral hygiene instructions, supragingival removal of plaque and calculus and 0.05% Chlorhexidine mouthrinse). Periodontal parameters including plaque index (PI), gingival index (GI), bleeding on probing (BOP), periodontal probing depth (PPD) and clinical attachment loss (CAL) were examined. Metabolic parameters, including fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c), and high-sensitivity C-reactive protein (hs-CRP) were evaluated at baseline and at 1, 3, and 6 months of follow-up. ResultsThe test group significantly improved all periodontal parameters and reduced metabolic parameters and hs-CRP, whereas improvements in PI and GI were observed in the control group at 1, 3 and 6 months of follow-up. However, the PPD, CAL, metabolic parameters and hs-CRP increased in the control group at 3 and 6 months of follow-up, but the differences were not significant. ConclusionsNSPT improves the periodontal status of smokers with T2D, has a favorable effect on glycemic control and reduces pro-inflammatory mediators, which may limit complications due to T2D in these patients.
