Oral health-related quality of life of 8-10 yearold children with traumatic dental injury

Abstract

Introduction: Children presents high prevalence of traumatic dental injury (TDI). Objective: It is very important to detect the impact on oral health related to quality of life (OHRQoL) in this age group. Methods: Based on this, a cross sectional study was carried out using a convenience sample. Children from 8-10 years with TDI in permanent teeth were recruited over an 18 month period, from a public University. Data about OHRQoL using the Brazilian version of CPQ8-10(B-CPQ8-10) were collected. TDI were classified according to Andreasen criteria and grouped according to its severity. Variations in the scores and impact of TDI on OHRQoL according to age, gender and TDI severity were examined using nonparametric statistical tests (Kruskall-Wallis and Mann-Whitney test, p<0.05). Results: From a sample of 255 children, 41 healthy children that suffered TDI in permanent were included in the study. The mean B-CPQ8-10 scores were 29.7 (SD 14.3). Emotional and social wellbeing domais had the highest negative score impact average 8.8 (SD 5.9) and 9.8 (SD 6.3), respectively. Gender or TDI severity did not present relation to impact on OHRQoL. In relation to age, 10-year-old children had more impact on their OHRQoL on the overall scale (p<0.05) and for the functional limitation subscale (p<0.05). Conclusion: TDI impacts negatively on OHRQoL of children aged from 8-10 years old.
