Caries experience, obesity and demographic factors in school children: A cluster analysis.

Objective: To determine the association between caries experience, obesity, and socioeconomic and environmental factors in 2, 5 and 12 years-old schoolchildren. Secondarily, the influence of school infrastructure was assessed.

Methods: Primary data from 1762 schoolchildren from the municipality of Cajamar (SP, Brazil) and socioeconomic and environmental secondary data (Brazilian Census 2010, School Census, Prova Brasil/2017) were used.

Validity and reliability of the quality of masticatory function questionnaire applied in Brazilian adolescents.

Purpose proper chewing and swallowing functions have great importance in general health, since it potentially affects food's digestion and the subject's nutritional status. The aim was to assess the validity and reliability of the self-applied Quality of Masticatory Function Questionnaire (QMFQ) in a convenience (non-referred) sample of Brazilian adolescents divided into three groups: control (n=57), dental caries (n=51) and malocclusion (n=54). Methods caries and malocclusion were evaluated using DMF-S index (number of decayed, missing and filled primary and permanent surfaces) and Index of Orthodontic Treatment Need, respectively.
