Abstract: This before-after experimental study evaluated the impact of dental treatment on the oral health-related quality of life (OHRQoL) in children aged 6–8 years from Paranoá, DF, considering the presence or absence of cavitated dentin carious lesions pre- and post-treatment. The responsiveness and sensitivity of the questionnaires were also investigated. Caries was detected by using the Caries Assessment Spectrum and Treatment (CAST) instrument, while the impact of oral health on the children's health-related quality of life was assessed using the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10), which was completed by the children and the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS), which was completed by their parents. Sociodemographic characteristics were also assessed. After the examinations, the children were categorized into two groups according to the presence (treatment/n = 34) or absence (control/n = 34) of cavitated dentin carious lesions. Restorative/curative care was provided to the treatment group, while the control group received preventive measures. OHRQoL was assessed at baseline and at four weeks post-treatment. No significant sociodemographic differences were observed between the groups. In the treatment group, the children and their families reported a greater impact of oral health on their OHRQoL in both questionnaires (p < 0.05). However, there was a significant reduction in the impact of oral health, with differences between the pre-treatment and post-treatment phases (p = 0.001). Good sensitivity and responsiveness were observed for both questionnaires. Dental treatment was found to reduce the negative impact of dental caries on OHRQoL in 6–8-year-old children, which was detected by both questionnaires (B-ECOHIS and CPQ8-10).

Resumo Introdução Pouco se sabe sobre os fatores associados à dor das crianças no tratamento odontológico sob sedação consciente. Objetivo Verificar a associação entre as características pré-operatórias e a dor durante o tratamento odontopediátrico sob sedação. Material e método Este estudo exploratório foi realizado com 27 crianças submetidas a tratamento restaurador sob sedação. As informações sobre idade, sexo e experiência de tratamento odontológico prévio da criança foram obtidas por meio de entrevista aos pais. A condição bucal, determinada a partir da presença de cárie dentária, foi verificada por meio do índice ceo-d. A dor foi avaliada por análise dos vídeos dos tratamentos, por dois examinadores previamente calibrados, utilizando-se os itens “pernas”, “atividade” e “choro” da escala observacional “Face, pernas, atividade, consolabilidade e choro” (FLACC). Os dados foram analisados por meio de testes bivariados. Resultado A maioria das crianças (n=14; 51,8%) não teve dor durante o tratamento odontológico sob sedação. Entre as demais crianças, observaram-se escores de dor baixos ou moderados (mediana 1,1; mínimo 0-3,8). Os escores FLACC não diferiram conforme sexo (P=0,38), experiência prévia de tratamento odontológico (P=0,32) e história de anestesia local (P=0,96). Os escores FLACC não se correlacionaram significativamente com idade (Spearman rho= -0,08; P=0,67) e ceo-d (Spearman rho= -0,04, P=0,84). Conclusão: Neste grupo de crianças, a dor durante tratamento odontológico sob sedação foi pouco observada, de baixa intensidade e não se associou a idade, sexo, condição bucal e experiência odontológica anterior.

Abstract Introduction Little is known about the factors associated with the pain of children in dental treatment under conscious sedation. Objective To investigate the association between preoperative characteristics and pain during pediatric dental treatment under sedation. Material and method This exploratory study was conducted with 27 children in restorative treatment under sedation. Information on age, sex and experience of the children with previous dental treatment was obtained through interviews with parents. Oral health status, determined from the presence of dental caries, was verified using the dmf-t index. Pain was assessed by analyzing videos of the dental treatments by two previously calibrated examiners, using the items “legs”, “activity” and “crying” of the observational scale “face, legs, activity, consolability and crying” (FLACC). Data were analyzed using bivariate tests. Result Most of the children (n=14, 51.8%) had no pain during dental treatment under sedation. Among the other children, lower or moderate pain scores (median 1.1; minimum 0 to 3.8) were observed. The FLACC scores did not vary according to sex (P=0.38), previous experience with dental treatment (P=0.32) and history with local anesthesia (P=0.96). The FLACC scores did not correlate significantly with age (Spearman rho= -0.08, P=0.67) and dmf-t (Spearman rho= -0.04, P=0.84). Conclusion In this group of children, pain during dental treatment under sedation was of low frequency and intensity and did not associate with age, sex, oral condition and previous dental experience.
