Influence of maternal dental anxiety on oral health–related quality of life of preschool children

A cross-sectional study was conducted with 608 mother–child dyads during the Children’s National Immunization Campaign in Pelotas, Brazil. Mothers answered a questionnaire on dental anxiety (DAS), socioeconomic status, use of dental services, and perception of their child’s OHRQoL (ECOHIS). The ECOHIS includes a child impact section (symptoms, function, psychological, self-image/social interaction domains) and a family impact section (parent distress and family function domains). Clinical examination of the children was performed to assess dental caries, dental trauma, and occlusal traits occurrence. The association assessment used Poisson regression models (RR; 95%CI, P ≤ 0.05).
