Current discoveries imply a connection between periodontitis and metabolic associated fatty liver disease (MAFLD). This study aimed to determine the prevalence of periodontitis and MAFLD in obese patients with BMI40, employing the most reliable diagnostic methods, namely liver biopsy, and detailed periodontal examination.Liver biopsy and periodontal examination were performed in 30 obese patients with BMI BMI40 undergoing bariatric surgery. Kleiner's classification was used to determine non-alcoholic steatohepatitis (NAS) activity score, non-alcoholic steatohepatitis (NASH) and liver fibrosis. The periodontal condition was classified following the recent AAP/EFP classification. Patients were divided into periodontitis (PG) and non-periodontitis groups (NPG). Data on systemic health parameters were collected from patients' medical records. Descriptive statistics and simple statistical tests were used to determine the differences between the two groups.The prevalence of NASH in the sample was 43% (13/30), borderline NASH 37% (11/30), while fibrosis stage 1 was most common (72%, [22/30]). Periodontitis prevalence was 67% (20/30), while all non-periodontitis patients (33%; 10/30) exhibited gingivitis. PG and NPG did not differ in NAS or NASH prevalence (p0.05). However, the periodontitis group showed higher C-reactive protein levels, while NPG showed higher gamma-glutamyl transpeptidase levels (p0.05).The study results suggest the considerable prevalence of MAFLD, periodontitis and gingivitis in obese patients with BMI40 undergoing bariatric surgery. Patients with periodontitis had higher CRP levels, while those with gingivitis presented higher gamma-glutamyl transpeptidase levels.

IntroductionWe aimed to determine if periodontal health deteriorates after bariatric surgery (BS).Material and methodsA search was performed in Medline and Embase, for prospective cohort studies with data on change in periodontal parameters after BS. Me�ta-analysis was performed with available data.ResultsThe results of 4 included studies consistently show significant (pConclusionsBS may have a transient negative consequence on periodontal health.

Background In obese patients, periodontitis might be associated with deprived systemic health. Edmonton obesity staging system (EOSS) is a new tool for classification of obesity that considers the metabolic, physical, and psychological health. The cross-sectional study aimed to evaluate the periodontal status of morbidly obese patients eligible for bariatric surgery and the association between periodontitis, obesity-related comorbidities, and EOSS. Methods Morbidly obese patients eligible for bariatric surgery underwent detailed periodontal examination and were divided into the periodontitis group (PG) and the non-periodontitis group (NPG). The medical and demographic data were obtained from medical files, while behavioural data were obtained by the interview. Descriptive statistics and simple statistical tests were used to summarise the characteristics of the sample and the differences between PG and NPG. The logistic regression models were used to calculate the association (odds ratio (OR)) between periodontitis and obesity-related diseases and EOSS. Results The study included 79 patients, with an average BMI of 44.6 kg/m2 (SD = 7.2). The prevalence of periodontitis was 65% (CI 95% 53%-75%). PG patients (n = 51) were older, more often smokers and were more often hypertensive than NPG patients (n = 28) (p p = 0.021)) and age with adjusted OR 1.06, (95% CI 1.01–1.13; p = 0.038)), while other tested conditions (diabetes, dyslipidaemia, and smoking habits) did not show significant association with periodontitis. Periodontitis did not correlate with EOSS or other obesity-related comorbidities (p > 0.05). Conclusion The morbidly obese patients eligible for bariatric surgery show a high prevalence of periodontitis and, therefore, are advised to be examined by a dentist before undergoing surgery. They have higher odds of hypertension but not of other obesity-related diseases or higher stages of EOSS. The medical personnel should raise awareness among obese patients on the potential association of poor periodontal health with hypertension. Trial registration NCT04653714.

The aim of the present study was to evaluate the potential of minimally invasive periodontal treatment using repeated photo-activated oral disinfection (PAD) with red light emitting diodes as an adjunct to ultrasonic scaling (US) in the treatment of chronic periodontitis. In a single-centred, randomized clinical trial involved 40 patients with untreated chronic periodontitis received US with repeated 3 episodes of PAD (test group) or US alone (control group). Clinical parameters (plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD), clinical attachment level (CAL)) were recorded for 12 months and subgingival biofilm analyses for five periodontal pathogens (A. actinomycetemcomitans (Aa), P. gingivalis (Pg), P. intermedia (Pi), T. forsythia (Tf), T. denticola (Td)) were performed for 6 months. Supportive periodontal treatment (SPT) was repeated every 3 months during the clinical trial, additional one episode of PAD was also applied in the test group. Both treatment modalities improved clinical parameters after 3 months and SPT maintained favourable clinical outcomes during 12 months. There were no statistical significant differences between the treatment groups. Statistical significant reduction of Aa, Pg, Tf, Td (p
