Resumen
Objetivos: Determinar la prevalencia de conductos C-shaped en molares inferiores (primeros y segundos molares) de la de la V región de Valparaíso, identificando su configuración radicular y características demográficas utilizando tomografía de haz cónico (CBCT).
Materiales y método: 912 molares (456 primeros y 456 segundos molares) resultantes del análisis de 228 tomografías CBCT mandibulares (89 hombres y 139 mujeres entre 15 y 80 años) fueron evaluados. Mediante una reconstrucción panorámica y cortes tomográficos axiales se estableció la configuración radicular y se clasificó la presencia y tipo de conducto C-shaped, analizando 5 niveles a lo largo de la raíz. Los datos fueron analizados estadísticamente con un intervalo de confianza del 5%.
Resultados: De los 912 molares analizados, 69 fueron clasificados como C-shaped (7,57%), constituyendo un 65,72% de los molares que presentaron raíces fusionadas. El 100% de esta configuración de conductos fue observada en segundos molares inferiores, presentando una mayor prevalencia en mujeres (n=49, 71,01%). El 40,82% de los casos que presentaron una configuración C-shaped se manifestaron bilateralmente. La configuración de conductos C-shaped más frecuente fue C3 (n=347, 66,10%) según la clasificación de Melton.
Conclusión: Los conductos C-shaped fueron observados en su totalidad en segundos molares inferiores mostrando una clara predileccion por el sexo femenino. Molares inferiores con raíces fusionadas deben ser evaluados cuidadosamente por la alta probabilidad de presentar este tipo de configuración radicular.
Objectives: To determine the prevalence of C-shaped canals in lower molars (first and second molars) of the V region of Valparaíso, identifying their root configuration and demographic characteristics using cone beam tomography (CBCT). Materials and method: 912 molars (456 first and 456 second molars) resulting from the analysis of 228 mandibular CBCT scans (89 men and 139 women between 15 and 80 years old) were evaluated. By means of a panoramic reconstruction and axial tomographic sections, the root canal configuration was assessed and the presence and type of C-shaped canal were classified, analyzing 5 levels along the root. Data were statistically analyzed with a 5% confidence interval. Results: Of the 912 molars analyzed, 69 were classified as C-shaped (7.57%), constituting 65.72% of the molars that presented fused roots. 100% of this configuration of canals was observed in lower second molars, presenting a higher prevalence in women (n = 49, 71.01%). 40.82% of the cases that presented a C-shaped configuration manifested bilaterally. The most frequent C-shaped canal configuration was C3 (n = 347, 66.10%) according to Melton's classification. Conclusion: The C-shaped canals were observed entirely in lower second molars showing a clear predilection for the female sex. Lower molars with fused roots should be carefully evaluated due to the high probability of presenting this type of root configuration.
