Purpose:
To investigate the root canal characteristics of mandibular central incisors using a cone-beam computed tomography (CBCT) technique.
Methods:
One hundred and fifty patients (79 males and 71 females) receiving CBCT scan at Shanghai Ninth People's Hospital were recruited into this study. A total of 295 image samples of mandibular central incisors were obtained and analyzed in terms of the number and type of root canals.
Results:
The majority of mandibular central incisors had a single canal (61% possessed a Type I canal system). Although 39% of the roots possessed two canals, only 8.8%had two separate apical foramina.
Conclusions:
The prevalence of two canals of mandibular central incisors in this case series was 39% and is within the range reported by previous studies on case series of different racial origin.
