Tooth movement, orofacial pain, and leptin, interleukin-1β, and tumor necrosis factor-α levels in obese adolescents.

Objectives: To evaluate tooth movement, orofacial pain, and leptin, interleukin (IL)-1β, and tumor necrosis factor (TNF)-α cytokine levels in the gingival crevicular fluid (GCF) during orthodontic treatment in obese adolescents.

Materials And Methods: Participants included adolescent patients aged 12-18 years: group 1, obese (n = 30), and group 2, nonobese controls (n = 30). They were evaluated before (T0) and after 1 hour (T1), 24 hours (T2), and 1 week (T3) of fixed appliance bonding.

Erosion and abrasion-inhibiting in situ effect of the Euclea natalensis plant of African regions.

This study evaluated the effect of Euclea natalensis gel on the reduction of erosive wear with or without abrasion, in enamel and dentin. During two five-day experimental crossover phases, volunteers (n = 10) wore palatal devices containing human enamel and dentin blocks (E = 8 and D = 8). The gel was applied in a thin layer in the experimental group, and was not applied in the control group.

Nutritional status, tooth wear and quality of life in Brazilian schoolchildren.

Objective: To evaluate the correlation among nutritional status, tooth wear and quality of life in Brazilian schoolchildren.

Design: The study followed a cross-sectional design. Nutritional status was measured via anthropometry using BMI and tooth wear was measured using the Dental Wear Index; both these assessments were carried out by a trained recorder according to standard criteria.

Oral manifestations in HIV+ children in Mozambique.

The scope of this study was to identify the prevalence of oral manifestations in HIV+/AIDS patients at the DIA Pediatric Hospital of Maputo. All 90 patients were included in the research. Data on dental caries (dmft/DMFT index), soft tissues and saliva flow were analyzed.

Dental caries in adolescents from public schools in Maputo, Mozambique.

Aim: To assess dental caries prevalence in adolescents at urban and sub-urban areas of Maputo-City, Mozambique and to identify its relationship with dental fluorosis, dental plaque, nutritional status, frequency of sugar consumption and the concentration of fluoride in public water supply.

Methods: Subjects (n=601) were randomly selected from five urban schools and five sub-urban schools. Clinical examinations were performed under standardised conditions by a trained examiner using DMFT index, SiC index, fluorosis index, PHP, BMI, a sugar consumption questionnaire and water supply analysis.
