Improvement on oral health related quality of life after orthosurgical treatment: a mixed methods study

Abstract The aim of this study was to understand the influence of orthosurgical treatment on oral health-related quality of life (OHRQoL) in patients with Class II and III skeletal malocclusion by conducting a mixed method case series study. Nineteen patients submitted to orthosurgical treatment in a private practice in Brazil were included in the sample. Data were collected retrospectively and interviews were held from March 2020 to July 2021. Patients answered to the Oral Health Impact Profile (OHIP-14) in the first part of the interview and subsequently answered the qualitative questions. The overall mean of OHIP-14 after treatment was 4.21 (SD 4.68). The qualitative data were analyzed according to thematic analysis and four themes emerged from the interviews: a) concept of quality of life, b) pre-treatment life, c) post-treatment life, and d) positive and negative aspects of treatment. Quality of Life was reported by the patients as the absence of feeling pain, having emotional and physical health, having a satisfactory esthetic appearance and self-esteem. Before treatment, most Class II patients used to complain about breathing and sleeping problems, while Class III patients complained more intensely about esthetics. Pain was a common problem reported by both Class II and Class III patients. In general, improvement was perceived in self-esteem, esthetics, function and pain. Complaints about negative aspects of the treatment were restricted to the postoperative period. The orthosurgical treatment was important for improving the OHRQoL of patients in terms of esthetic, functional and psychosocial aspects.

Evaluation of 1211 third molars positions according to the Classification of Winter, Pell & Gregory / Evaluación de posiciones de 1211 terceros molares acorde a la Clasificación de Winter, Pell & Gregory

Panoramic radiographs are important for the evaluation and classification of the third molars position, allowing the diagnosis and planning of extraction. The objective of this study is to evaluate upper and lower third molars positions in panoramic radiographs with the classification methods proposed by Pell and Gregory (1933) and Winter (1926) and the subsequent comparison of results with other authors. Panoramic radiographs of 310 patients were analyzed, 197 female and 113 male, totaling 1,211 third molars. In relation to the upper third molars, the most prevalent positions were: angle compared to the long axis of the second molar of Distoangular form (53.23 %) and the depth of impaction as Class C (48.25 %). In the lower third molars, the most prevalent positions were: angle to the long axis of the second molar in Mesioangular classification (52.96 %), the depth of impaction was B (46.54 %) and the tooth relationship with the mandibular ramus was identified as class I (55.26 %). These results provide information that can be utilized in predicting third molar development in terms of impaction or eruption, assisting dental surgeons in making decisions regarding surgical planning and treatment.

Las radiografías panorámicas son importantes para la evaluación y clasificación de la posición de los terceros molares, lo que permite el diagnóstico y la planificación de la extracción. El objetivo de este estudio fue evaluar terceros molares superiores e inferiores y posiciones en las radiografías panorámicas con los métodos de clasificación propuestas por Pell & Gregory, y Winter y la posterior comparación de los resultados con otros autores. Se analizaron las radiografías panorámicas de 310 pacientes, 197 mujeres y 113 hombres, con un total de 1.211 terceros molares. En relación con los terceros molares superiores, las posiciones más prevalentes fueron: ángulo con respecto al eje longitudinal del segundo molar de forma distoangular (53,23 %) y la profundidad de la impactación como Clase C (48,25 %). En los terceros molares inferiores, las posiciones más prevalentes fueron: ángulo con respecto al eje longitudinal del segundo molar en la clasificación mesioangular (52,96 %), la profundidad de impactación fue de B (46,54 %) y la relación de los dientes con la rama mandibular fue identificado como Clase I (55,26 %). Estos resultados proporcionan información que puede ser utilizada para predecir el desarrollo del tercer molar en términos de compactación o erupción, ayudando a los cirujanos dentistas en la toma de decisiones respecto a la planificación y el tratamiento quirúrgico.

Surgical Treatment of Condylar Hyperplasia Associated with Dentofacial Deformity: Low Condylectomy, Articular Disc Repositioning, and Orthognathic Surgery / Tratamiento Quirúrgico de Hiperplasia Condilar Asociado a la Deformidad Dentofacial: Condilectomía Baja, Reposicionamiento del Disco Articular y Cirugía Ortognática

Due to the complexity of the treatment of condylar hyperplasia associated with dentofacial deformities and its complications, if left untreated, the surgeon should be alert to these factors at the time of surgical planning to tailor the optimal therapy for an individual patient. This case report describes a patient with right condylar hyperplasia associated with dentofacial deformity who was treated surgically with low condylectomy, articular disc repositioning and anchoring, and orthognathic surgery, concomitantly, with stable results, satisfactory occlusion and facial harmony.

Debido a la complejidad del tratamiento de la hiperplasia condilar asociada con deformidades dentofaciales y sus complicaciones, si no se trata, el cirujano debe estar alerta ante estos factores en el momento de la planificación quirúrgica para adaptar la terapia óptima para cada paciente. Este caso describe un paciente con hiperplasia condilar derecha asociada con la deformidad dentofacial que fue tratado quirúrgicamente con condilectomía baja, reposicionamiento y anclaje del disco articular, y la cirugía ortognática, concomitantemente, con resultados estables, oclusión satisfactoria y armonía facial.
