Agreement between schoolchildren and their parents on rating the child's oral health-related quality of life.

The perceptions of parents/caregivers regarding their children's oral health can influence the standard of care and decision-making regarding oral health.

Aim: To investigate the association between prolonged breastfeeding and ECC at 48 months, while considering the interaction between prolonged breastfeeding and ultraprocessed foods (UPF).

Design: Data from a birth cohort study conducted in southern Brazil were used (n = 3645).

Impact of dental caries severity and activity on oral health-related quality of life among children aged 8-11 years.

Caries disease can lead to strong impact in terms of pain and suffering, to functional impairment, and to negative effects on quality of life. Studies have demonstrated that the impact on quality of life increases with dental caries severity, and few studies have assessed the relationship between caries activity and children's oral health-related quality of life (OHRQoL). This cross-sectional study aimed to assess the impact of dental caries severity and activity on the OHRQoL of schoolchildren.

Translation and cultural adaptation of the Illness Perception Questionnaire-Revised for Dental to Brazil.

This study aimed to translate and to perform the cultural adaptation of the instrument Illness Perception Questionnaire-Revised for Dental (IPQ-RD) into Brazilian Portuguese. The IPQ-RD consists of 34 items that assess the cognitive and emotional representation/perception of parents/caregivers of children with dental caries, with response options on a 5-point Likert scale, ranging from "Strongly agree" (score 1) to "Strongly disagree" (score 5). The higher the score, the lower the perception of the disease.
