Abstract

Objectives: The location of second mesiobuccal root canal (MB2) in maxillary molars is usually very difficult and generally easy to be missed. Frequency of mesiobuccal canal has been investigated by numerous authors using different methods including clinical and laboratory work. The objective of this study is to detect presence of MB2 canal in maxillary molars and distolingual canal in mandibular molars using CBCT and specifically to compare prevalence of presence of MB2 in maxillary molars and distolingual canals in mandibular molars between gender male and female and to compare prevalence of presence of MB2 canal maxillary molars and distolingual canal in mandibular molars between Malay, Chinese and Indians.

Materials and method: A descriptive study is conducted by examining CBCT of all patients in Faculty of Dentistry radiographic records. These patients had undergone scanning for various treatment modalities. Scanning was performed at USIM Dental Clinic between the periods of March 2012 until November 2014. The images had been evaluated by final year dental students. The present, number of MB2 canal in maxillary first permanent molar (FPM) and distolingual canal in mandibular first permanent molar (FPM) will be evaluated and record in a data collection sheet.

Result: In total of 89 patients, 158 teeth were examined consisting of upper and lower first molar. The number of maxillary FPM is 72 and mandibular FPM is 86. The prevalence of MB2 canal in male is 18% and in female is 10%. The prevalence of distolingual canal in male is 20% and in female is 10%. Out of 89 patients, 72 patients are Malay, 12 patients are Chinese and 5 patients are Indian. The presence of MB2 canal in Malay is 15 canals, 5 for Chinese and none were found in Indian patients. The presence of distolingual canal in Malay is 23 canals, Chinese 2 and Indian 1.

Conclusion: The incidence of MB2 canal and distolingual canal show slight difference between male and female. The incidence of MB2 canal and distolingual canal between races cannot be compared due to insufficient data. Since the examination was done by final year dental students, the result obtained was lower compared to the standard value of data provided in previous research.
