FREQUENCY OF SECOND MESIOBUCCAL CANAL IN MAXILLARY FIRST MOLAR DETECTED THROUGH CONE BEAM COMPUTED TOMOGRAPHY
The mesio-buccal root of the maxillary first molar is considered to be one of the most researched areas as compared to the other roots in the maxillary region.Failure to treat a secondary canal in permanent maxillary molar teeth is considered to be the most predominant reason leading to post treatment disease. Newer advanced techniques for assessing the MB2 canal have helped in effectively locating the secondary canal and hence its treatment.1
The objective of this study was to determine the frequency of the second mesio-buccal canal in permanent upper first molars in patients attending CMH Medical College Lahore. In total 100 teeth were examined using CBCT. Analysis of data was done by SPSS 20.0. The significance level was taken as 0.05.The mean and standard deviation were calculated for numeric variables like age. Percentage and frequency were calculated for categorical variable, like gender and number of canals. Fisher’s exact test was applied to assess the association between the presence of MB-2 canal and gender.
The frequency of 2nd MB2 canal was found to be 56%.Out of 100 patients the frequency for females was 19% and 37% for males.
The frequency of MB2 canal in maxillary 1st molar was high in examined patients (56%). No significant association was recorded for age, gender and the presence of MB2 canal
