Direct relations between sense of coherence and oral health-related quality of life in adolescents.

OBJECTIVE: To verify the relations between sense of coherence (SOC) and dental caries on oral health-related quality of life (OHRQoL) of adolescents. SUBJECT AND METHODS: A cross-sectional sample of 768 adolescents nested in a cohort study was evaluated. SOC was measured using Antonovsky's scale. Dental caries was collected considering the decayed, missing, and filled teeth index (DMFT). OHRQoL was collected through the Child Perception Questionnaire. Demographic, socioeconomic, and use of service variables were also collected. The mediation effects between variables were tested by structural equation modeling. RESULTS: The average age of the individuals was 17.5 years. Individuals with high SOC scores had a positive impact on OHRQoL (ß-coefficient = -0.573, p < 0.00). Individuals with high DMFT (ß-coefficient = 0.080, p = 0.034) and dental pain (ß-coefficient = 0.079, p = 0.039) negatively impacted OHRQoL. Still, adolescents who had dental pain (ß-coefficient = 0.112, p = 0.005), mothers with lower education levels (ß-coefficient = -0.114, p = 0.004), lower household income (ß-coefficient = -0.131, p = 0.003), and those who visited the dentist (ß-coefficient = 0.109, p = 0.005) exhibited a higher DMFT index. CONCLUSIONS: SOC and dental caries had a direct effect on OHRQoL, indicating that oral conditions and psychosocial characteristics are important contributors to OHRQoL.

Influence of malocclusion on oral health-related quality of life in children: a seven-year cohort study.

OBJECTIVE: To assess the influence of early childhood malocclusion on oral health-related quality of life (OHRQoL). METHODS: 7-year cohort study involving 639 preschoolers (1 to 5 years) who had been evaluated initially with a survey conduced in 2010. Children completed the Brazilian version of the Child Perception Questionnaire (CPQ8-10) to assess OHRQoL during the follow-up period. Exploratory variables were collected at baseline, including the presence and severity of malocclusion (overjet and lip coverage). Socioeconomic characteristics, oral health behavior, and patterns of dental attendance were also investigated. A multilevel Poisson regression model was used to fit the association between malocclusion and OHRQoL. With this approach, incidence rate ratio (IRR) and 95% confidence intervals (95% CI) were calculated. RESULTS: A total of 449 children were re-evaluated (follow-up rate, 70.3%). The prevalence of accentuated overjet and inadequate lip coverage was 13.5% and 11.9%, respectively. The mean (±SD) CPQ8-10 score was 10.57±10.32. The presence of inadequate lip coverage was associated with higher overall mean CPQ8-10 scores (IRR 1.51; 95% CI 1.29-1.77), and social well-being, emotional well-being, and functional limitation domains. Children with accentuated overjet (>3mm) also demonstrated higher overall scores on the CPQ8-10 than their normal counterparts. The presence of this condition also influenced the oral symptom (IRR 1.29; 95% CI 1.08-1.53) and emotional well-being (IRR 1.30; 95% CI 1.02-1.66) domains. CONCLUSION: Results of the present study suggest that early childhood malocclusion is a risk factor for low OHRQoL in future.

RESUMO Objetivo: Avaliar a influência da má oclusão na primeira infância na qualidade de vida relacionada à saúde bucal (QVRSB). Métodos: Este estudo de coorte de 7 anos envolveu 639 pré-escolares (1 a 5 anos) que foram avaliados inicialmente em um levantamento transversal conduzido em 2010. As crianças completaram a versão brasileira do Child Perception Questionnaire (CPQ8-10) para avaliar sua QVRSB no período do acompanhamento. Variáveis exploratórias foram coletadas na linha de base, incluindo a presença e severidade de má oclusão (sobressaliência e cobertura labial). Características socioeconômicas, hábitos de saúde bucal e padrões de assistência odontológica também foram investigados. Um modelo de regressão de Poisson multinível foi utilizado para medir a associação entre má oclusão e QVRSB. Com essa abordagem, calculou-se a razão de taxa de incidência (IRR, incidence rate ratio) e o intervalo de confiança de 95% (IC 95%). Resultados: No total, 449 crianças foram reavaliadas (taxa de acompanhamento de 70,3%). A prevalência de sobressaliência acentuada e cobertura labial inadequada foi de 13,5% e 11,9%, respectivamente. A média±DP de pontuação do CPQ8-10 foi 10,57±10,32. A presença de selamento labial inadequado foi associada com maiores médias na pontuação total do CPQ8-10 (IRR 1,51; IC 95% 1,29-1,77) e nos domínios de bem-estar social, bem-estar emocional e limitação funcional. Crianças com sobressaliência acentuada (>3 mm) também demonstraram médias nas pontuações do CPQ8-10 total maiores do que suas contrapartes normais. A presença dessa condição também influenciou os domínios de sintomas bucais (IRR 1,29; IC 95% 1,08-1,53) e bem-estar emocional (IRR 1,30; IC 95% 1,02-1,66). Conclusão: Os resultados do presente estudo sugerem que a má oclusão na primeira infância é um fator de risco para baixa QVRSB no futuro.
