Epidemiological and clinical characterization of Moyers class II syndrome division 1

Abstract

The development of an occlusion is the result of interactions between genetically determined factors and environmental factors. Malocclusions are an oral health problem of current importance, the motivation for this study. Its objective is to characterize from an epidemiological and clinical perspective Moyers class II syndrome division 1 in patients with permanent dentition. The cross-sectional descriptive observational study method was taken into account. The universe consisted of 103 patients, who met the inclusion criteria, the observed variables were operationalized and summarized based on descriptive statistics. In order to obtain results, in the population with class II Moyers syndrome division 1, bilateral predominated, ages between 12 and 14 years and the female sex. Clinically, characteristics such as deforming muscle function in the bilateral type and unilateral hyperactivity of the mental muscle (100%) affected (100%), respectively, vestibuloversion of the upper incisors (98.06%), and convex profile (81.55%), increased overhang, mandibular retrognathism, increased protrusion and V-arching (67.96%; 60.19%; 56.31% and 38.83% respectively). Reaching the conclusions that Moyers class II syndrome division 1 in patients with permanent dentition was characterized by the predominance in the ages between 12 and 14 years and the female sex. Clinically, from the distal molar relationship, it was characterized by the superiority of the bilateral type with deforming muscle function and the hyperactivity of the mental muscle in the unilateral one. The rest of the syndromic features described by the author were inconstant and infrequent.
