Aim: To assess the effect of periodontal treatment on HbA1c and diagnostic parameters of patients with metabolic syndrome (MetS). Materials and Methods: One hundred and fifty‐eight patients with MetS and moderate and severe periodontitis were included. They were randomized into a test group (n = 79), which received non‐surgical periodontal treatment, and a control group (n = 79), which received no treatment. Medical treatment was delivered to both groups. Clinical periodontal, anthropometric and serological parameters were assessed at baseline, 3 and 6 months. The main outcome was glycated haemoglobin (HbA1c) levels, and the secondary outcomes were changes in the MetS parameters, C‐reactive protein (CRP) and HOMA indexes. Results: Significant reductions in all periodontal parameters were observed in the test group, compared with the control group, at 3 and 6 months (p <.001). HbA1c levels, MetS parameters, CRP and HOMA indexes showed no significant differences between the test group and the control group at 3 and 6 months. Conclusions: Periodontal treatment led to a substantial reduction in periodontal inflammation, although there was no significant effect on the parameters used for MetS diagnosis in patients with early diagnosed and well‐controlled MetS.

Objective: This study aimed to systematically review the literature about the prevalence of self-reported depressive symptoms in dental students. Methods: PUBMED, SCOPUS, and EMBASE databases were search up to January 2020 with the following focused questions: "What is the prevalence of self-reported depression symptomin dental students?" and "Are sex and years of educational training associated with self-reported depressive symptom in dental students?". Observational studies that applied a questionnaire assessing depressionwere eligible. Standardmean differences (SMD) and pooled odds ratios (OR) were calculated for the questionnaires' scores and self-reported depressive symptom, respectively. Results: Fifty-eight studies were included, and 15 different questionnaires were used. The prevalence of self-reported depressive symptoms/at least mild depression ranged from 2.75% to 89.84%, and the pooled overall prevalence was 29% (95% confidence interval [CI]: 26-34). Meta-analysis showed significantly lower scores in the questionnaires for self-reported depressive symptoms of male students (SMD: -0.22; 95% CI: -0.42 - -0.03). Conversely, no significant difference was detected for the OR of self-reported depressive symptom in the comparison between sex (OR: 1.11 - 95% CI: 0.77-1.62). Similarly, no significant differencewas observed for the different school years regardless of the analytical strategy used. Conclusion: It was concluded that female dental students presented more selfreported depressive symptoms, but no difference is demonstrated during the years of dental education.

Summary This systematic review aimed to compare the nutritional status and oral health in older adults individuals. Three databases (Medline-Pubmed, Scopus and EMBASE) were searched up to October 28th 2016 for studies that performed the Subjective Global Assessment (SGA) or the Mini Nutritional Assessment (MNA) and an oral examination performed by a dental professional, either dental hygienist or a dentist. Both observational and interventional studies were screened for eligibility. Meta-analyses were performed comparing the malnourished/at risk of malnutrition and the normal nutrition subjects with three oral health parameters (edentulism, use of prosthesis and mean number of present teeth). Twenty-six studies were included in the systematic review, of which 23 were cross-sectional. It was showed that well-nourished subjects had a significantly higher number of pairs of teeth/Functional Teeth Units (FTU) in comparison to individuals with risk of malnutrition or malnutrition. The meta-analyses showed no statistically significant association between edentulism and use of prosthesis, as the pooled Relative Risk were, respectively, 1.072 (95% CI 0.957–1.200, p = 0.230) and 0.874 (95% CI 0.710–1.075, p = 0.202). On the other hand, the pooled Standard Mean Difference of mean number of present teeth were −0.141 (95% CI −0.278 to −0.005, p = 0.042) in subjects with at risk of malnutrition/malnourished. FTU and mean number of teeth present were significantly associated with nutritional status. Furthermore, more longitudinal studies in this field are needed. [ABSTRACT FROM AUTHOR]
