ABSTRACT
ABSTRACT The present study aimed to investigate the occurrence of mandibular canal alterations in regions with dental inflammation by means of cone beam computed tomography (CBCT). A database of 2,484 CBCTs was reviewed for identifying dental inflammation in mandibular alveolar ridges. The final sample consisted of 150 CBCTs, including 91 females and 59 males, with ages ranging from 13 to 89 years (mean age of 47.06; ± SD=18.722). The presence and location of dental inflammation, gender, age, as well as presence and location of mandibular canal branching (MCB) were evaluated. The Kolmogorov-Smirnov, Chi-square, and T-test were applied to verify the statistical relationship of the data. There were 178 images of dental inflammation on 150 CBCTs, mainly located at molars' region (75 %). Apical lesions were the most common type of dental inflammation found (79 or 44.4 % of the sample), followed by pericoronitis (32; 18.0 %). This study identified 135 mandibular canal branches in the exams that presented dental inflammation. The MCB were also most commonly located at molars' region (74.07 %). No statistical difference was identified regarding the distribution of mandibular canal branching in relation to the sites with dental inflammation (p=0.370).The MCB found were mostly single (86 or 63.7 % of the total). Sex had no influence on mandibular canal branching occurrence (p=0.308), not did age (p=0.728). A high prevalence of mandibular canal branching was observed in the regions where dental inflammation were identified, most commonly found in the molar region.
RESUMEN
RESUMEN El presente estudio tuvo como objetivo investigar la ocurrencia de ramificación del canal mandibular (RCM) en regiones con inflamación dental mediante tomografía computarizada de haz cónico (TCHC). Se revisó una base de datos de 2.484 TCHC para identificar la inflamación dental en las crestas alveolares mandibulares. La muestra final consistió en 150 TCHC, incluidas 91 mujeres y 59 hombres, con edades comprendidas entre 13 y 89 años (edad media de 47,06 ± DE = 18,722). Se evaluaron el sexo, la edad, la presencia y la ubicación de la inflamación dental, así como la presencia y ubicación de RCM. KolmogorovSmirnov, Chi-cuadrado y prueba-T se aplicaron para verificar la relación estadística de los datos. Hubo 178 imágenes de inflamación dental en 150 TCHC, ubicados principalmente en la región de los molares (75 %). Las lesiones apicales fueron el tipo más común de inflamación dental encontrada (79 o 44,4 % de la muestra), seguidas por pericoronitis (32; 18,0 %). Este estudio identificó 135 ramas del canal mandibular en las regiones que presentaron inflamación dental. El RCM también se localizó con mayor frecuencia en la región de los molares (74,07 %). No se identificaron diferencias estadísticas con respecto a la distribución de la ramificación del canal mandibular en relación con los sitios con inflamación dental (p = 0,370). Las RCM encontrados fueron en su mayoría solteros (86 o 63,7 % del total). El sexo no tuvo influencia en la ocurrencia de la ramificación del canal mandibular (p = 0,308), no la edad (p = 0,728). Se observó una alta prevalencia de ramificación del canal mandibular en las regiones donde se identificó la inflamación dental, que se encuentra con mayor frecuencia en la región molar.
