This study aimed to assess the impact of mild traumatic dental injury (TDI) on the oral health-related quality of life (OHRQoL) of 8–10-year-old children of low socioeconomic status.
Subject and methods
A total of 111 children aged 8–10 years old with TDIs were randomly selected from public schools. Clinical oral examinations were performed for the diagnosis of TDI following Andreasen’s classification. Experience of dental caries and presence of malocclusion were determined according to WHO and Dental Aesthetic Index (DAI) criteria. The Brazilian version of the Child Perceptions Questionnaire (CPQ8–10) was used to evaluate the OHRQoL. Statistical analysis involved Fisher’s exact test and the Mann–Whitney test.
The prevalence of TDI was 8.1%. Only mild TDIs were found, the most common type being enamel fracture (63.6%). No significant differences were found in any of the CPQ8–10 subscale scores or the total CPQ8–10 scores for children with and without dental trauma (p > 0.05).
The present study suggested that mild TDIs did not have a negative impact on the OHRQoL of children aged 8–10 years old of low socioeconomic status.
