Perceived outcomes and satisfaction of Saudi parents and their children following dental rehabilitation under general anesthesia: A 2-year follow-up.

PURPOSE: To investigate the perceived clinical outcome and parents' satisfaction after dental rehabilitation under general anesthesia over a follow-up period of 2 years. MATERIALS AND METHODS: A prospective study of questionnaire data obtained from 352 pediatric patients before and after treatment of early childhood caries with full dental rehabilitation under general anesthesia. Questionnaires focused on oral symptoms, functional limitations, and emotional and social well-being before and after dental treatment. Cases were followed up for 2 years postoperatively. RESULTS: A dramatic disappearance of symptoms was reported from parents' perspective. There was a high satisfaction rate (99.14%) also among parents of the children included in the study. CONCLUSION: Children with early childhood caries do not necessarily express it verbally as pain. The disease has a lot of other expressions affecting children's behavior and habits, including the ability to sleep, thrive, and socialize. This study contributes to the existing literature that full dental rehabilitation under general anesthesia [dental general anesthesia (DGA)] has an immediate positive impact on the physical and social quality of life of children suffering from early childhood caries as well as on their families. Postoperative preventive care, early diagnosis, and treatment of recurrent caries are key factors to maintain postoperative outcome of DGA.

Biomechanical effects of fixed functional appliance on craniofacial structures.

OBJECTIVE: To evaluate displacement and stress distribution on craniofacial structures associated with fixed functional therapy. MATERIALS AND METHODS: A finite element model of the human skull was constructed from sequential computed tomography images at 2-mm intervals using a dry adult human skull. In this study, linear, four-nodal, tetramesh and triangular shell elements were used with six degrees of freedom at each of their unstrained nodes: three translations (x, y, and z) and three rotations (around the x-, y-, and z-axes). RESULTS: The entire mandible moved anteroinferiorly. Maximum displacement was observed in the parasymphyseal and midsymphyseal regions. The pterygoid plate was displaced in a posterosuperior direction. The anteroinferior displacement of the mandibular dentition was most pronounced in the incisor region, while the maxillary dentition was displaced posterosuperiorly. The entire dentition experienced tensile stress except for the maxillary posterior teeth. Tensile stress was also demonstrated at point A, the pterygoid plates, and the mandible, and minimal compressive stress was demonstrated at anterior nasal spine. Maximum tensile stress and von Mises stresses occurred in the condylar neck and head. CONCLUSION: Fixed functional therapy causes a posterosuperior displacement of the maxillary dentition and pterygoid plate and thus can contribute to the correction of Class II malocclusion. The displacement was more pronounced in the dentoalveolar region as compared to the skeletal displacement. All dentoalveolar structures experienced tensile stress, except for anterior nasal spine and the maxillary posterior teeth.
