Impact of crown fracture treatment on oral health-related quality of life of children, adolescents, and their families: A prospective clinical study

Background Enamel-dentin fracture causes impact on the oral health-related quality of life (OHRQoL) of children. Aim To evaluate the impact of treatment of crown fracture involving enamel and dentin (CFED) in the permanent dentition on the OHRQoL of children and adolescents (C/As) and their families. Design This prospective clinical study included C/As between 8 and 14 years who presented anterior CFED treated thought direct composite resin restoration. Their parents/caregivers (P/Cs) were also invited to take part of the study. The quality of life was evaluated thought the Child Perceptions Questionnaires (CPQ(8-10) and CPQ(11-14)), Parental-Caregiver Perceptions Questionnaire (P-CPQ), and Familiar Impact Scale (FIS), applied before and 3 months after the restorative procedure. T test for dependent samples and Wilcoxon test were applied(P < 0.05). Results Of 32 C/As included, 30 completed the study. The treatment of CFED reduced the negative impact in OHRQoL of C/As (CPQ(8-10) P = 0.0065; CPQ(11-14) P = 0.0486; P-CPQ, P = 0.0259), specially for oral symptoms (CPQ(8-10), P = 0.0003; P-CPQ, P = 0.0455) and emotional well-being (CPQ(11-14), P = 0.0431). Concerning the families' perceptions, the treatment did not influence OHRQoL both in terms of the domains and total FIS score (P > 0.05). Conclusion Restorative treatment of CFED increases the OHRQoL of C/As but not influence the OHRQoL of their families.
