Abstract
ABSTRACTObjective: To assess the impact of two early treatment protocols for anterior dental crossbite on children’s quality of life. Methods: Thirty children, 8 to 10 years of age, with anterior dental crossbite, participated in this study. Individuals were divided into two groups: Group 1 - 15 children undergoing treatment with an upper removable appliance with digital springs; Group 2 - 15 children undergoing treatment with resin-reinforced glass ionomer cement bite pads on the lower first molars. Quality of life was evaluated using the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10), which contains four subscales: oral symptoms (OS), functional limitations (FL), emotional well-being (EW), and social well-being (SW). A higher score denotes a greater negative impact on children’s quality of life. Children answered the questionnaire before treatment (T1) and twelve months after orthodontic treatment onset (T2). Descriptive statistics, the Wilcoxon test and analysis of covariance (ANCOVA) were performed. Results: Children’s mean age was 9.07 ± 0.79 years in Group 1 and 9.00 ± 0.84 years in Group 2. For Group 1, the FL and EW subscale scores and the overall CPQ8-10 were significantly higher in T1 as compared to T2 (p= 0.004, p= 0.012 and p= 0.015, respectively). For Group 2, there were no statistically significant differences. The ANCOVA showed no significant difference regarding quality of life at T2 between groups, after controlling for quality of life measures at T1.Conclusions: The difference regarding the impact on quality of life between groups is not related to the protocol used.
Highlights
The concept of oral health-related quality of life (OHRQoL) has been used to measure the impact of oral outcomes on the functions and quality of life of individuals.[1]
Group 1 scores for the functional limitations (FL) and emotional well-being (EW) subscales and the overall CPQ8-10 score were significantly higher in T1 as compared to T2 (p = 0.004, p = 0.012, and p = 0.015, respectively)
The results of the analysis of covariance (ANCOVA) showed no significant difference in the subscale and CPQ8-10 overall scores at T2 between the two types of treatment protocol (Group 1 and Group 2), after controlling the model for children’s measures of quality of life at T1 (Table 3)
Summary
The concept of oral health-related quality of life (OHRQoL) has been used to measure the impact of oral outcomes on the functions and quality of life of individuals.[1]. Studies evaluating these changes reported the possibility of periodontal problems in the lower incisors, the presence of discomfort, alteration in the anteroposterior position of the mandible, and problems with the temporomandibular joint (TMJ), when the problem is not treated early.[6,7] Interceptive orthodontic intervention in the mixed dentition allows the orthodontist to correct the anterior crossbite earlier in a way that promotes the harmonious growth of the bone bases,[8,9] mitigating the chances of severe disorders in the permanent dentition
