ABSTRACT
BACKGROUND: The variety of characteristics related to odontoma research, including an unexplored one such as size, merits a multivariate approach that allows the adequate drawing of inferences with pertinent conclusions. The objective of this study is to establish the possible association between some characteristics related to the odontoma, tumor size among them. MATERIAL AND METHODS: The sociodemographic characteristics of 60 patients were evaluated. Diagnosis, size, location, type of treatment performed, and prognosis were determined. These data were analyzed descriptively and through multivariate models. RESULTS: Thirty-four compound and 26 complex odontomas in 32 men and 28 women were observed. The age average of patients was 15.6±11 years. Most of the odontomas presented a size inferior to 10 mm. A statistically significant association was observed between the routine radiographic finding and the absence of dental eruption (p=0.0001). The model of linear regression adjusted between odontoma size and age (ß=0.321, p=0.01), as well as the model of logistic regression adjusted between gender (men) and tumor size (OR=12; 1.7 - 93 IC 95%, (p=0.01) were statistically significant. CONCLUSIONS: Statistically significant associations between odontoma size and age, and between the male gender and odontomas smaller than 10 mm were found adjusting by other confounding variables. These results could grant clinicians a greater knowledge of the context of odontoma characteristics, which in turn could favor a better diagnostic and therapeutic decision-making. Key words:Odontoma, compound odontoma, diagnosis, multivariate analysis.
ABSTRACT
Maxillofacial injuries can cause significant long-term functional, esthetic, and psychological complication. Besides, these injuries may pose a substantial economic consequence for the patients as the treatment may involve a complex procedure. The purpose of the current retrospective study was to investigate the pattern of maxillofacial fractures in Medellín, Colombia over a 13-year period (1998-2010). A retrospective study of 2680 subjects with 4893 maxillofacial fractures admitted at the Oral and Maxillofacial Surgery Department of the San Vicente de Paul University Hospital in Medellín, Colombia, is presented. The patients were evaluated by age, gender, etiology, type of injury, treatment modalities and hospitalization time. The Chi-Square test was used to compare the counts of categorical response between two independent variables. The study population consisted of 2193 males and 487 females with a mean age of 26.5 (SD: 13.5) years. The age group 21-30 years accounted for the largest subgroup in both sexes. The most common cause of the fractures was traffic related followed by interpersonal violence. There were mainly mandibular, maxilla alveolar process and zygomatic bone fractures in both males and females, accounting for approximately 92 percent of all fractures. The main fracture site of the mandible was the mandibular condyle. The results of the present study reveal that road traffic accidents remain among the main reasons of maxillofacial fractures. Measures on prevention of road traffic crashes and policies that strengthen social investment should be strongly emphasized in order to reduce the occurrence of these injuries.
Las lesiones maxilofaciales pueden causar complicaciones funcionales, estéticas y psicológicas significativas a largo plazo. Además, pueden representar una consecuencia económica sustancial para los pacientes, y su tratamiento puede implicar un procedimiento complejo. El propósito de este estudio retrospectivo fue investigar el patrón de las fracturas maxilofaciales en Medellín, Colombia en un período de 13 años (1998-2010). Se estudiaron 2.680 pacientes con 4.893 fracturas maxilofaciales, quienes ingresaron al Departamento de Cirugía Oral y Maxilofacial del Hospital Universitario San Vicente de Paúl en Medellín, Colombia. Los pacientes fueron evaluados clasificados según edad, sexo, etiología de la fractura, tipo de lesión, tratamiento y tiempo de hospitalización. Se utilizó la prueba de chi-cuadrado para comparar los conteos de respuestas categóricas entre dos variables independientes. La muestra se conformó por 2.193 hombres y 487 mujeres, con una edad promedio de 26,5 años (DE 13,5). El grupo entre 21-30 años fue el más numeroso. La causa más común de fracturas fue el accidente de tránsito, seguido por la violencia interpersonal. En ambos sexos se observaron, principalmente, fracturas de la mandibula, proceso alveolar maxilar y hueso cigomático; aproximadamente el 92 por ciento de todas las fracturas. En la mandíbula, el sitio principal de fractura fue el cóndilo mandibular. Los resultados revelan que los accidentes de tránsito aun son la principal causa de fractura maxilofacial. Se debe enfatizar en medidas de prevención de los accidentes de tránsito, junto a políticas que fortalezcan la inversión social con el fin de reducir la aparición de estas lesiones.
