Prevalence of xerostomia and its association with systemic diseases and medications in the elderly: a cross-sectional study.

Background: Dry mouth syndrome or xerostomia is defined as decreased salivary flow or hypofunction of salivary glands. Its origins are multicausal and might be the result of a change in the salivary glands or a systemic imbalance.

Objective: To ascertain the prevalence of self-reported xerostomia and to identify associated factors.

Racial and regional inequalities of dental pain in adolescents: Brazilian National Survey of School Health (PeNSE), 2009 to 2015.

The aim of the study is: (a) investigate the racial inequalities as one specific dimension that affects dental pain in Brazilian adolescents; and (b) investigate the regional variations of dental pain. This cross-sectional study used data from Brazilian National Survey of School Health (PeNSE), carried out with adolescents in 2009, 2012 and 2015. Dental pain was evaluated through the question: "Did you have dental pain in the last six months?".

Parent-child interaction and stimulation in early life can be related to caries in primary dentition? Hypotheses from a life-course approach.

Dental caries has common risk factors with impairments in growth, cognitive development and child general health. Identifying socioeconomic contexts and parental behaviors in early life that may be associated with negative outcomes in the child's future and their causal mechanisms can contribute to planning early interventions. Therefore, the aim of this paper is to propose and discuss possible ways to explain how early childhood stimulation may be associated with future oral health status, based on the life-course theory of chain-of-risk model and accumulation of risk model.
