Abstract

Background: To investigate the oral health-related quality of life (OHRQoL) and associated factors among a sample from East China with severe early childhood caries (S-ECC).

Methods: A total of 316 children with S-ECC and their parents were recruited to participate in a cross-sectional study. Children were examined for caries status using criteria proposed by World Health Organization (WHO). The accompanying parent was required to provide demographic information and complete two validated questionnaires in Chinese: the early childhood oral health impact scale (ECOHIS) and the 5-item oral health impact profile (OHIP).

Results: The study had a 98.1% response rate. Finally, the data of 300 children and their parents were analyzed. Mothers cared for their children far more than fathers in the included family (78.7% mother, 21.3% father). The mean age of children was 4.1 ± 0.7 years, ranging from 3 to 5. The mean dmft score was 13.8 ± 3.8. Few (13.7%) children never had a toothache. ECOHIS scores ranged from 0 to 38, with a mean score of 16.2 ± 7.2. The mean OHIP score was 2.9 ± 2.7. The parental age, family income, residence, history of pain, the dmft scores and parents' OHIP showed associations with ECOHIS scores or domain scores (P < 0.05). The multiple regression analysis showed that the history of pain, accompanying parents' OHIP, and the dmft scores were mainly associated with ECOHIS and child impact (P < 0.05); parental age was associated with family impact (P = 0.024).

Conclusions: The parent's OHRQoL was associated with the children's OHRQoL, indicating that policymakers and clinical practitioners should improve both children's and their parents' oral health. Furthermore, the caries severity and the history of dental pain impacted children's OHRQoL.
