The COVID-19 pandemic worsened pre-existing barriers to dental care access, increasing inequalities and negatively impacting children’s oral health. Objective: Analyzing the use of dental services and its impact on oral health-related quality of life among preschool children in Salvador, Brazil, and to identify factors associated with service utilization and quality of life in this group. Methods: This cross-sectional study included 523 children aged 26 to 80 months enrolled in public municipal daycare centers in Salvador, Bahia. Data were collected using a clinical oral health assessment form and a self-administered questionnaire completed by parents or guardians, addressing sociodemographic characteristics, dietary and oral habits, and use of dental services. Dental caries experience was assessed, and oral health-related quality of life was measured using the Brazilian version of the Early Childhood Oral Health Impact Scale (B- ECOHIS), with scores categorized according to impact level. Descriptive, bivariate, and multivariate analyses were performed using linear regression, with a 95% significance level. Results: Dental caries were present in 41.87% of the children, and low utilization of dental services during the pandemic was observed (15.68%). Age, family income, presence of dental caries, and experiences of fear or anxiety were significantly associated with the overall B-ECOHIS score, highlighting inequalities in access to dental services and their impact on children’s oral health-related quality of life. The use of dental services showed little impact on oral health-related quality of life in this population. Conclusion: Dental caries and socioeconomic factors significantly influenced oral health-related quality of life among preschoolers, while dental service utilization during the pandemic was limited and had minimal impact, reinforcing the need for equitable public oral health strategies for early childhood.

The anatomical connection between the oral cavity and the lungs provides many opportunities for the oral microbiota to impact the lung microbiota in health and disease. In addition to the possibility of passive transfer of bacteria, changes in the composition of the oral microbiota can lead to a deficient immune response and reduced tolerance to commensal microorganisms. The present observational study aimed to carry out a metagenomic investigation of the subgingival biofilm of individuals with severe asthma, mild asthma and without asthma, to evaluate the relationship between the subgingival microbiome and asthma. Subgingival biofilm samples were collected from thirty individuals at the Asthma Control Program Outpatient Clinic in Bahia (ProAR). They were distributed into six groups, according to diagnosis for asthma and periodontitis. Total DNA extraction and metagenomic analysis were performed using next-generation sequencing based on the 16s-rRNA gene (Illumina MiSeq). Data were analyzed descriptively, using the average of the samples of each group. For ecological analysis, alpha diversity was estimated using the Shannon index, and beta diversity using principal coordinate analysis (PCoA) and the Bray-Curtis distance method. This study provides the first insights into the composition of the subgingival microbiome in individuals diagnosed with periodontitis and different diagnoses of asthma. The presence/greater abundance of genera considered more pathogenic from the periodontal point of view, like Aggregatibacter, Treponema, Selenomonas e Campylobacter, can be seen in individuals with severe asthma and periodontitis. At the same time, there is a greater risk towards dysbiosis for individuals with asthma and without periodontitis, especially with severe asthma, who have higher levels of Porphyromonas. New studies are suggested based on the genera highlighted in this research.

To this end, two studies were conducted: a systematic review with meta-analysis to assess whether obesity interferes with the control of clinical periodontal parameters after periodontal treatment, and a cross-sectional study to investigate the association between obesity and periodontal inflammation in users of public health services. The systematic review included 14 articles submitted to methodological quality assessment using the ROBBINS-1 tool, which presented a low to moderate risk of bias. The findings of the qualitative assessment of the studies showed that there was an improvement in clinical periodontal inflammatory parameters in all investigations for obese and non-obese individuals after non-surgical periodontal treatment. The meta-analysis results showed that there were statistically significant differences between obese and non-obese individuals for the percentages of probing depth and clinical attachment level between 4 and 6 mm after three months of periodontal therapy. For the crosssectional study, all the subjects underwent a periodontal examination, had anthropometric measurements taken and answered a questionnaire containing information on their socioeconomic status, health and lifestyle. Excess body weight was defined using the Body Mass Index (BMI) and waist circumference (WC) criteria of the International Diabetes Federation (IDF) and the National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP-III) criteria. Periodontal inflammation was quantified using Periodontal Inflamed Surface Area (PISA) values with a cut-off point of ≥191mm². The measure of association was obtained by Poisson regression analysis with robust variance, adjusted and controlled. The results indicated poor oral conditions among obese individuals and the association between obesity and periodontal inflammation was statistically significant for the obesity criterion according to NCEP-ATP-III (PR: 1.22; 95%CI: 1.04-1.41, p=0.01), after adjusting for gender, age, schooling and hypertension. The results of this investigation indicate the influence of obesity on the control of periodontal inflammation.

MATERIAL AND METHODS: In this cross-sectional study, periodontal and periimplant clinical examination were performed on a sample of 71 volunteers. Peri-implant mucositis was defined as the presence of blending on probing in association with redness, swelling or suppuration, without bone loss. Peri-implantitis was defined as radiographic image of bone loss ≥ 3 mm or probing depth ≥ 6 mm, associated with bleeding and/or suppuration on probing. The systemic factors were evaluated by clinical examination or questionnaire and included obesity, hormone replacement therapy, osteopenia and osteoporosis, hypertension and hypercholesterolemia. Logistic models were applied to assess associations between peri-implant diseases and systemic factors (p≤0.05). RESULTS: Mucositis and peri-implantitis were found in 70.4% (n=50) and 15.5% (n=11) of the sample, respectively. The regression analysis showed that hormone replacement therapy decreased the risk for peri-implant mucositis (PR = 0.40, 95% CI: 0.21-0.95; p =0.04), whereas systolic hypertension (PR = 4.48, 95% CI: 1.38-35.48; p = 0.01) increased the risk for peri-implantitis. The other systemic factors were not associated with peri-implant diseases. CONCLUSION: Hormone replacement therapy decreased the risk of peri-implant mucositis, whereas high systolic blood pressure increased the risk of peri-implantitis. Consequently, patients with high systolic blood pressure should be informed before implant placement and more frequently re-called for maintenance visits. While hormonal monitoring may be suggested in women with persistent peri-implant mucositis.
