Objectives The upper molars generally have three roots; therefore, different combinations of fusion can occur, increasing the possibility of finding more complex root canal systems. The purpose of this study was to evaluate the prevalence and characterization of fused roots in first and second maxillary molars using cone-beam computed tomography (CBCT) in a Colombian population. Materials and Methods A total of 1274 teeth were evaluated, of which 534 were maxillary first molars and 740 were maxillary second molars. Axial sections were made at the cervical, middle, and apical levels to determine the prevalence of root fusion and the types of fusion. Results Overall, 43% of the molars ( n = 551) presented some type of fused root. Root fusion was present in 23.4% of the maxillary first molars. The most frequent type of fused root was type 3 (distobuccal-palatal; DB-P) (58.9%). Root fusion was observed in 57.6% of the maxillary second molars, and the most prevalent type of fused root was type 6 (cone-shaped) (45.2%). Of the maxillary molars, 12.5% were classified as C-shaped. Conclusion Within the limitations of this study, there was a high prevalence of fused roots in maxillary molars in the Colombian population, mainly in the maxillary second molars. In first molars, the most common type of fused root was type 3 (DB-P) and in second molars, the most common type was type 6 (cone-shaped). Additionally, molars with root fusion presented variation at different levels of the radicular portion, with implications for treatment quality.
Objetivo: presentación de un reporte de caso sobre una variación morfológica del canal dentario mandibular. Método: Se muestra evidencia radiográfica en una mujer adulta procedente del área urbana de Manizales –Colombia, que presenta aumento de tamaño del canal dentario sin evidencia clínica de deformidad mandibular ni sintomatología, el cual podría asociarse a tumoración benigna, debido al comportamiento que tiene desde que se encontró como hallazgo radiográfico en el 2013. Resultados: Los estudios biométricos del canal dentario determinan un diámetro promedio de 2.5 mm en condiciones de normalidad, lo que hace considerar esta expansión como una alteración del nervio alveolar inferior. Conclusiones: Se reporta una alteración expansiva ósea de un mega conducto dentario mandibular.

Morbilidad oral de la población subsidiada de Manizales atendida en el modelo docencia-servicio en una clínica universitaria. Rev Nac Odontol. 2014;10(19):7-13. doi: http://dx.doi.org/10. 16925/od.v10i19.841 Resumen. Introducción: el objetivo de esta investigación fue conocer la morbilidad oral de la población subsidiada de Manizales atendida en el modelo docencia-servicio en una clínica universitaria. Materiales y métodos: este estudio descriptivo consideró una población de estudio de 122 pacientes de todas las edades adscritos al régimen subsidiado. Se analizaron variables sociodemográficas, antecedentes sistémicos y alteraciones orales como: alteraciones en la superficie dental, gingivales, periodontales, de la oclusión, pulpares, periapicales, articulares, de la estructura dental, fractura dental, resto radicular, alveolitis, celulitis y fluorosis dental. Resultados: la población que más asistió a consulta pertenece al sexo femenino, con 62,2% (76) de pacientes; la población que más adherencia presentó a la consulta está en el rango de 15 a 44 años de edad, con 64,7% (79) de pacientes; las cinco primeras causas de morbilidad oral en los pacientes fueron caries en dentina, enfermedades de origen pulpar, enfermedad periodontal, trastorno de atm y raíz dental retenida. Solo tres pacientes eran mayores de 60 años, que presentaron alteraciones periodontales como diagnóstico más representativo. La mayor frecuencia de cop fue de 17,7, correspondiente al grupo etario de 60 años o más. Conclusiones: la caries y la enfermedad periodontal siguen siendo los diagnósticos con mayor prevalencia en la consulta odontológica.Palabras clave: morbilidad oral, caries dental, enfermedad periodontal, modelo docencia-servicio. Oral Morbidity in the Subsidized Population of Manizales Served through the TeachingService Model at a University ClinicAbstract. Introduction: the purpose of this research was to determine oral morbidity in the subsidized population of Manizales served through the teaching-service model at a university clinic. Materials and methods: the descriptive study looked at a study population of 122 patients of all ages affiliated with the subsidized system. Sociodemographic, systemic precedents and oral alterations were analyzed, such as changes in the dental, gingival and periodontal surfaces, occlusion, pulp, periapical bones, joints, dental structure, dental fracture, rest of the root, alveolitis, cellulitis and dental fluorosis. Results: women made up the majority of those using the service, 62.2% (76 patients); the population showing greatest adherence was between the ages of 15 and 44, accounting for 64.7% (79 patients); the five leading causes of oral morbidity were dentine cavities, diseases originating in the pulp, periodontal disease, tmj disorder and retained dental root. Only three patients were older than 60 and their most common diagnoses were periodontal alterations. The highest cop frequency was 17.7 and involved t...
