The aim of the present study was to determine the prevalence of oral mucosal conditions and associated factors among 541 preschoolers of low socioeconomic status. A cross-sectional study was carried out. Sociodemographic data and information on harmful oral habits were gathered with the use of a questionnaire. A clinical exam was performed for the determination of oral mucosal conditions, dental caries and level of oral hygiene. Data analysis involved statistical analysis, the Kruskal-Wallis test, Mann-Whitney test, chi-square test, Fisher's exact test and multivariate regression (p < 0.05, 95 % CI). The prevalence of oral mucosal conditions was 40.7 %. The most prevalent oral mucosal conditions were coated tongue (23.4 %), melanotic macules (14.4 %), oral ulcers (11.8 %), Fordyce's spots (8.1 %), angular cheilitis (3.0 %), geographic tongue (2.8 %), linea alba (1.5 %) and fistula (1.3 %). Children between 3 and 5 years of age had a greater chance of exhibiting coated tongue (OR, 2.55; 95 % CI, 1.6-4.1), melanotic macules (OR, 4.07; 95 % CI, 2.3-7.2) and Fordyce's spots (OR, 12.70; 95 % CI, 7.2-28.6). The female gender had a greater chance of exhibiting melanotic macules (OR, 2.23; 95 % CI, 1.3-1.8). Coated tongue was more prevalent among children from low-income families (OR, 2.35; 95 % CI, 1.3-4.3) and those with inadequate oral hygiene (OR, 4.65; 95 % CI, 2.9-7.4). Caries constituted a predictive factor for oral ulcers (OR, 2.15; 95 % CI, 1.2-3.9) and fistula (OR, 12.00; 95 % CI, 1.4-11.3). Bruxism (teeth clenching/grinding) was a predictive factor for angular cheilitis (OR, 5.55; 95 % CI, 1.9-16.3). The determinant factors for oral mucosal conditions were the female gender, age between 3 and 5 years, inadequate oral hygiene, low household income, residence in rural areas and presence of dental caries and bruxism.

SUMMARY:The aim of this research was to assess the hemodynamic variations during the extraction of impacted lower third molars using lidocaine 2 % or articaine 4 %, as local anesthetics. Fourteen patients with a mean age of 22.4 (SD=3.25), were submitted to the bilateral extraction of lower third molars, with an interval of three to four weeks between the two extractions. Systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate and oxygen saturation in the blood were assessed at seven specific time points: baseline; anesthetic puncture; two minutes after anesthesia; osteotomy; suture and five minutes after the procedure had been completed. The statistical analysis involved descriptive analysis, the Shapiro-Wilk test, the Mann-Whitney test, the t-test and the repeated measurements test. No significant differences were found for any of the hemodynamic behavior variables when comparing lidocaine 2 % and articaine 4 %. Significant differences were found between the time points assessed within each group, particularly in relation to the variable heart rate. In the articaine group, systolic blood pressure exhibited a significant decrease five minutes after the procedure. There were no significant variations in hemodynamic behavior between the two different anesthetic groups (articaine 4 % and lidocaine 2 %).

Aim:The aim of the present study was to assess the periodontal condition and sensitivity of second mandibular molars after the extraction of the adjacent third molar, while also assessing the quality of life of the patients.Materials and Methods:Twenty-three healthy patients were assessed in terms of probing depth, gingival height, gingival thickness, dental sensitivity, plaque index and bleeding on probing (adjacent second mandibular molar), before the surgical procedure, as well as 60 and 180 days after the surgery. The following data were also recorded and measured: the position and size of the impacted teeth; the size of the alveoli after surgery and the quality of life of the patient.Results:Significant differences were found for probing depth and gingival height before and after 180 days. The plaque index increased significantly after surgery (P = 0.004), as did bleeding on probing. No significant difference was found for the quality of life. The size of the third molar extracted was correlated with bleeding on probing 180 days after the surgery.Conclusion:An improvement was noted in the periodontal condition of the second mandibular molars after the extraction, based on the assessments of probing depth and gingival height. The position of the third molar affected the periodontal condition of the second mandibular molar. No alterations were recorded for dental sensitivity or the quality of life after the extraction.
