Aim: To determine the racial difference of the mandibular canal positions in dentate Malaysians using the Cone Beam Computed Tomography (CBCT) and Simplant interactive software.
Methods: The samples for this study included imaging of 60 patients (30 males and 30 females) from the Division of Oral Radiology, with ages ranging from 20 to 60 years (mean age, 47 years). The measurements of the mandibular canal length were done in coronal view of the jaw at every 1cm interval from the mental foramen backwards (D1-Da); the position of the mandibular canal was measured at four different locations.
Results: One way ANOVA test showed that there were no significant differences for the location of mandibular canal at D1 amongst the races, while there were significant differences for mandibular canal location at D2,D3 and D4. A more statistjcal analysis showed that at D2 location, significant difference was observed befween Chinese and Indians (P:0.005) while there was no difference between the others. At D3, significant difference was noticed between Malays and Chinese (p:0.038) and also between Chinese and Indians Gr:0.002). Significant differences was noticed at D4 befween Malays and Chinese (p:0.0a9) and between Chinese and lndians (p:0.028).
Conclusion: Based on our findings, it was observed that there was no significant difference in the location of canal at D1 position. However, when we advanced posteriorly in the mandible there was an obvious variation of the position of the canal amongst the races; therefore clinicians should be aware of this variation in the Maiaysian population.
