To evaluate the timing, duration and incidence of bacteremia following invasive dental procedures (IDPs) or activities of daily living (ADL). Eight databases were searched for randomized (RCTs) and nonrandomized controlled trials (nRCTs) evaluating bacteremia before and after IDPs or ADL in healthy individuals. The risk of bias was assessed by RoB 2.0 and ROBINS‐I. For the meta‐analysis, the primary outcomes were the timing and duration of bacteremia. The secondary outcome was the incidence of bacteremia, measuring the proportion of patients with bacteremia within 5 min after the end of the procedure compared with baseline. We included 64 nRCTs and 25 RCTs. Peak bacteremia occurred within 5 min after the procedure and then decreased over time. Dental extractions showed the highest incidence of bacteremia (62%–66%), followed by scaling and root planing (SRP) (44%–36%) and oral health procedures (OHP) (e.g., dental prophylaxis and dental probing without SRP) (27%–28%). Other ADL (flossing and chewing) (16%) and toothbrushing (8%–26%) resulted in bacteremia as well. The majority of studies had some concerns RCTs or moderate risk of bias nRCTs. Dental extractions, SRP and OHP, are associated with the highest frequency of bacteremia. Toothbrushing, flossing, and chewing also caused bacteremia in lower frequency. [ABSTRACT FROM AUTHOR]

Background: Scaling and root planning (SRP) is the gold standard for non‐surgical periodontal treatment. Green tea as a supporting alternative in non‐surgical periodontal treatment has been suggested as a therapeutic option in the treatment of periodontitis. Objective: To analyse the comparative effectiveness of green tea (Camellia sinensis) in its different forms and applications for the treatment of periodontitis. Methods: We included randomized clinical trials evaluating green tea as an adjuvant therapeutic agent to scaling and root planning (SRP) in the treatment of periodontitis. For the meta‐analysis, we calculated standardized mean difference (SMD) and 95%CI comparing green tea and control (only SRP). We subgrouped by types of application forms of green tea. The certainty of the evidence was assessed through GRADE. Results: Nine studies were included. The follow‐up time of treatments varied from 21 days to 6 months. The subgroup meta‐analysis showed that the green tea as sachet reduced probing bleeding (SMD = −0.71; 95%CI) and the gingival index (SMD = −0.78; 95%CI) compared to SRP with very low certainty of evidence. The sachet (SMD = −0.29; 95%CI) and dentifrice (SMD = −1.31; 95%CI) reduced plaque index with very low certainty compared to the control. All forms of application of green tea showed very low certainty of evidence (SMD = −0.27; 95% CI) in reducing the probing depth, as well as for the loss of clinical insertion (SMD = −0.42; 95% CI) with low certainty of evidence. Conclusion: There was not a difference in the effectiveness of green tea isolated or in combination with SRP to reduce probing depth. Green tea adjunct to periodontal therapy showed very low certainty of effectiveness for the treatment of periodontal disease. [ABSTRACT FROM AUTHOR]

Investigations into the oral health status of indigenous populations are scarce. The aim of this study was to evaluate caries experience and associated factors among 342 indigenous children and adolescents aged 5-15 years of the Xukuru community in the municipality of Pesqueira, Brazil. A cross-sectional census study was carried out using the criteria of the World Health Organization to determine caries experience. Examinations were performed by two calibrated dentists and a questionnaire was administered to parents/caregivers addressing socio-demographic data, diet and oral hygiene habits. Logistic regression analysis were performed, with dmft and DMFT as the dependent variables (P < 0.05). Caries experience (dmft/DMFT) was high in both the primary and permanent dentition (75.6% and 62.9%, respectively). Mean dmft and DMFT indices were 3.11 and 2.21, respectively. Caries experience in the primary dentition was associated with children residing in villages far from urban areas (P = 0.016), while caries in the permanent dentition was associated with older children (P < 0.001) and with children from villages at an intermediate distance and far from urban areas (P < 0.001). The indigenous subjects exhibited a high degree of caries experience, which was associated with age and group of villages. Public policies are needed to improve the oral health status of this population. [ABSTRACT FROM AUTHOR]

Objective: The aim of the present study was to assess the association between smoking and both behavioral and environmental factors among adolescents in the public school system in the city of Campina Grande (northeastern Brazil)., Methods: An analytical cross-sectional study was carried out involving 574 schoolchildren between 10 and 19 years, with the use of a structured questionnaire addressing behavioral factors, environmental factors and smoking. The chi-squared test and Fisher's exact test were used for the statistical analysis (5 % level of significance)., Results: The prevalence of smoking was de 3.3 %. The lowest age regarding the use of tobacco for the first time was eight years and the age group with the greatest frequency of initiation into this habit was 11 to 14 years (44.3 %). A total of 84.3 % of tobacco users smoked between one and 10 cigarettes per day. Smoking was associated with delays in schooling (p=0.047), gender (p=0.016), alcohol use and frequency of alcohol use (p<0.001) and the relationship with one's father (p=0.014) and mother (p=0.004)., Conclusions: Despite the low prevalence, an early initiation into smoking was found, suggesting that educational campaigns should be directed at earlier ages. Alcohol use stood out among the variables studied, suggesting that smoking is influenced by both the use and intensity of this substance.
