“…The total sample consisted of 495 cases, with 71.1% females and 28.3% males. Regarding sexual dimorphism in the mandibular symphysis, men had a higher mean value for symphysis width than women (Table V), which is in agreement with the results obtained in other studies in which this parameter was analyzed [6,15,18,[21][22][23][24][25][26][27][28][29][30]. In this research, men had an average width of 14.66 mm against 13.95 mm for females.…”

Objectives. Facial perception depends on the different components of the face. The chin is a striking anatomical structure in the individual’s identity and mandibular symphysis (MS) shape influences the adjacent soft tissue, determining facial harmony. In lateral cephalometry, the MS corresponds to the image of the mandibular body in its anterior curvature. It shape, inclination and thickness provide valuable information for orthodontic diagnosis and prognosis. Since facial features are associated with malocclusions, the present investigation aims to relate the height, thickness and inclination of the MS using Angle’s Class. Methods. 495 lateral incidence cephalograms of an orthodontic population were analyzed using a previously developed and tested software. The sample was randomly selected and the height, thickness and inclination of the MS were measured. The values were statistically analyzed (p ≤ 0.05). Results. The distribution according to Angle’s Class was 48.9% for Class I, 34.7% for Class II Division 1, 7.4% for Class II Division 2 and 8.9% for Class III. The MS height did not´t show significant differences between the three dental classes. The MS thickness was significantly increased in Class II Division 2 and Class I subjects (p = 0,037). The MS inclination was significantly less in Class III subjects when compared to Class I and Class II Division 1 (p ≤ 0.001). Conclusions. The MS presented variations, which may be associated with a natural compensation against malocclusion, influencing the position of the teeth and their relationship with the other dento-craniofacial structures and with consequences on the facial harmony.

“…La biomecánica y su función articular por diversos parámetros ante un paciente con patología disfuncional se necesita el estudio y la corrección de los elementos que contribuyen en esta patología. Cuando existe alteración de la dimensión vertical repercute tanto en su sistema neuromuscular como el propioceptivo perjudicando su capacidad de adaptación (Linjawi et al, 2021;Lee et al, 2021& Goldstein et al, 2021.…”

“…Se debe considerar que la dimensión vertical puede producir un aumento o disminución. Esto se da por causas iatrogénicas, debido a que se realiza una rehabilitación protésica inadecuada (Linjawi et al, 2021).…”

El cáncer es una problemática de salud pública que, en la mayoría de los casos, en sus estados iniciales transcurre de manera silenciosa, por lo que una incipiente lesión bucal puede evolucionar y aportar a los valores porcentuales de incidencia y prevalencia de casos diagnosticados por cáncer bucal. El presente libro servirá de marco teórico para futuras investigaciones, pues todos los contenidos abordados son de interés profesional, basados en estudios bibliográficos, epidemiológicos y clínicos resultantes de proyectos de investigación. El conocimiento de las lesiones bucales es de mucha utilidad durante el ejercicio profesional y la prestación del servicio comunitario para los profesionales de la salud y egresados de la carrera de odontología, ya que permite realizar el diagnóstico y la prevención temprana de los factores de riesgo, predisponentes y desencadenantes de las lesiones bucales paraprotéticas.
