Introduction:One of the major causes of treatment failure is the impossibility of locating and treating the entire root canal system, a result of the lack of knowledge of the dentists about internal or external anatomy of the tooth and the high complexity and variation of the root canal system, with accessory, secondary, recurrent, apical delta canals, and type of canals under (Vertucci et.al. 1984) classification.Recently, Cone-beam computed tomography (CBCT) has the ability to recognize the anatomy in a detailed manner and reconstruction of the anatomical part in a 3D image, from axial, transverse and sagittal planes, and gives clear image and specification about pulp tissue inside the canals in different dimensions with no anatomical superposition.(Betancourt et.al. 2015).
Purpose: The aim of the present study is to determine the prevalence of second mesiobuccal canal in maxillary permanent molars and investigate root canal configuration in the maxillary permanent molar teeth using cone-beam computed tomography (CBCT) in population from Makkah.
Materials and methods: Cone-beam computed tomography (CBCT) images were examined in this study. 300 samples were obtained from individuals attended to Umm Qura University dental teaching hospital. The images were evaluated for the present of second mesiobuccal canal in maxillary permanent molars. Images were examined by a radiologist, endodontist and two dental interns.
The collected data were tabulated and statistically analyzed with p value ≤ 0.05.
Results:300 samples were taken from Cone-beam computed tomography (CBCT) images of regular dental patients who took CBCT images for other purposes, 152 females (50.7%) and 148 males (49.3), with age range from 18 to 50 year old. 129 samples showed second mesiobuccal Canal in maxillary molars with percentage of (43%). 76 male samples out of 148 total male samples had second mesiobuccal canal with percentage of (25.3%). 53 female samples out of 152 had second mesiobuccal canal with percentage of (17.7 %). Occurrence of Second mesiobuccal canal in maxillary molars was significantly higher in males relative to females, p= 0.004.
Conclusions: Second mesiobuccal canal in maxillary molars appeared in 43% of the samples. It can be concluded that the CBCT images are noninvasive and clinically efficient tool in understanding root canal anatomy and configuration, so it can improve the outcomes of root canal treatment.
