Prevalence and C-shaped root canal configuration in lower molars in the metropolitan region, Chile

Objetive: The aim of this study was to determine the prevalence, demographics, and root configuration C-shaped canals mandibular molars by means cone beam computed tomography in population Metropolitan Region, Chile. Material Methods: 912 (456 first 456 second molars) resulting from analysis 228 CT scans were evaluated. established a panoramic reconstruction axial tomographic sections, classifying presence type through five sections or cuts along root. Data statistically analyzed using 5% confidence interval. Results: Of analyzed, 70 classified as (7.68%), corresponding 58.33% those that presented fused roots. 95.7% canal observed lower molars, occurring more frequently females (n=45, 64.29%). 45.65% cases bilateral most frequent C3 (n=401, 66.63%) according Melton classification. Conclusion: studied mainly showing clear prevalence among high percentage bilaterality. roots significantly increases possibility finding configuration.
