Mean ECOHIS total score was not influenced by maternal dental anxiety. However, anxiety had a negative effect on the perception of the impact of the child's oral health problems in the family, affecting the parent distress domain.
Use of dental care services by preschool children was low, and treatment was neglected even among children who had visited a dentist. Children of mothers with low schooling level who do not visit a dentist regularly were at greater risk of not receiving dental care. Maternal perception of their child's oral health motivated visits to the dentist.
Dental trauma in primary teeth is characterized as an accident that occurs due to the children's development stage, even when they are cared for by mothers of higher schooling and income. Parents should search for assistance right after trauma occurrence to minimize sequelae.
A high percentage of schoolchildren suffered from dental pain, which was influenced by demographic, socioeconomic, psychosocial, and clinical characteristics, causing a negative impact on oral health perception.
More research is needed to know whether the techniques are effective for improving behavior and reducing children's pain and distress during dental treatment. However, the majority of the techniques improved child's behavior, anxiety, and pain perception.
The aim of this study was to estimate the impact of malocclusion on the oral healthrelated quality of life (OHRQoL) of schoolchildren aged 8-12 years old in Southern Brazil. A two-stage cluster procedure was used to select 1,199 children in 20 public and private schools in Pelotas/Brazil. Cross-sectional data was collected, consisting of a socioeconomic questionnaire to parents, children's interview and clinical oral examination. The clinical variables were obtained from clinical examination, and the Child Perceptions Questionnaire (CPQ) was assessed during children's interview. To measure malocclusion and orthodontic treatment need the Dental Aesthetic Index was used. For data analysis multiple Poisson regression models estimating the rate ratios (RR) and their respective confidence intervals (95%CI) were used. Among 1,206 participants, 789 were aged 8-10 years and 417 between 11-12 years. The orthodontic treatment need was higher among the younger children (44.6%) than in the older ones (35.0%) (p value ≤0.05). There was a significant association in the CPQ social and emotional domains with malocclusion in the older schoolchildren. In the adjusted analysis (for socioeconomics and clinical variables) the effect of very severe malocclusion on OHRQoL was confirmed in both 8-10 and 11-12 age groups (RR(95%CI) of 1.24(1.02;1.51) and 1.28(1.01;1.62), respectively). The findings demonstrated that children with very severe malocclusion experienced greater negative impact on OHRQoL compared to those with mild or no malocclusion. The results suggest that malocclusion impacts the quality of life. The higher impact occurs in the social and emotional well-being domains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
