Resumo: | Introduction: The anterior dental crossbite is defined as a malocclusion resulting in sagittal direction of the lingual position of the upper incisors in relation to the lower. This malocclusion can be corrected early in mixed dentition using different interceptive treatment protocols proposed in the literature. Objectives: 1) to compare the efficacy of two early treatment protocols of previous dental crossbite. 2) compare the impact of these two treatment protocols in the quality of life of children. Materials and Methods: In this thesis were presented in addition to the initial and final thoughts on the subject and extended methodology of the research project, two scientific papers which involved a sample of 30 children aged 8 to 10 years divided into two groups: Group 1 - 15 children treated with upper removable appliance with digital springs positioned in the palatal face of the cross elements and Group 2 - 15 children treated with resin glass ionomer cement stop on the occlusal of the lower first permanent molars promoting disclusion and the movement of cross-teeth tongue action. In the first article, the comparison of the effectiveness of the protocols was carried out by assessing the overjet, upper arch perimeter, intercanine distance in the maxilla and mandible, SNA, SNB and ANB. In the second article, the evaluation of the quality of life of participants was carried out by the Brazilian version of the instrument Child Perceptions Questionnaire (CPQ8-10). In both articles, the 30 participants were evaluated before treatment (T1) and 12 months after the installation of protocols (T2). Results: In the first article, Group 1 showed a significant increase in overjet (p <0.001) of the distance intercanine jaw (p = 0.006) and intercanine distance from the jaw (p = 0.031). Group 2 showed a significant increase in overjet (p = 0.008) and intercanine distance jaw (p = 0.005). For all variables, no statistically significant differences between the two groups. In the second article, for Group 1, the scores of the subscales LF and BE and the total score of CPQ8-10 were significantly higher in T1 compared to T2 (p = 0.004, p = 0.012 and p = 0.015 respectively). For Group 2, there were no statistically significant differences. Conclusions: In the first article, it was concluded that the anterior dental crossbite in mixed dentition can be corrected successfully by the two proposed treatment protocols. In the second article, it is concluded that treatment with upper removable appliance with digital springs was associated with more positive changes in the quality of life of children. |
