ABSTRACT Aim The aim of this study is to assess the morphology of nasopalatine canal (NPC) with cone beam computed tomo-graphy (CBCT). Materials and methods A total of 460 subjects of both genders were subjected to CBCT with NewTom machine, and sagittal and coronal sections were used for evaluation of the shape of NPC and width of buccal cortical plate. Types of NPC were also assessed. Results Of 460 subjects, males were 210 and females were 250. The difference was nonsignificant (p = 0.1). Type III canals were mostly seen in both males and females, followed by types I and II. The mean length of NPC in males and females showed statistical significant difference (p < 0.05). Males showed significantly higher diameter of nasal opening, oral opening, and width of the buccal bone plate over the oral opening as compared with females. Conclusion The exact location, morphology, and dimensions of NPC can be well visualized with CBCT. All findings were higher in males as compared with females. Clinical significance The success of dental implant in maxillary anterior region may be affected by the approximation with NPC. The exact location and morphology play an important role for the correct placement of implant. Cone beam computed tomography is a useful tool providing three-dimensional images in all sections.

Objective To evaluate the apical surgery-related anatomy of two-rooted and three-rooted mandibular first molars (MFMs) in a Mongoloid population. Methods A total of 502 cone-beam computed tomographic images were used to evaluate the root configuration, the distance from the buccal bone to each root, root dimensions, and the complete root resection distance at the resection level for roots of MFMs. Results The prevalence of two-rooted and three-rooted MFMs was 85.1% and 14.9%, respectively. At the resection level, the distance from the buccal bone to the mesial and distal roots of two-rooted MFMs was 2.24 and 3.15 mm, respectively, while the distance was 2.44, 2.01, and 8.55 mm for the mesial, distobuccal, and distolingual roots of three-rooted MFMs, respectively. The distance from the buccal bone to each root was longer in men than in women. The largest distance for complete root resection was detected for the distal root in two-rooted MFMs and for the distolingual root in three-rooted MFMs. Conclusions The prevalence of three-rooted MFMs is common in the Mongoloid population. The distance from the buccal bone to root apex differs according to root configurations and sex. Surgical access to the distolingual root is difficult because of the long access distance.

ABSTRACT Objective: The aim of this study was to evaluate the skeletal and dental effects of rapid maxillary expansion (RME) in cleft patients using two types of expanders. Methods: Twenty unilateral cleft lip and palate patients were randomly divided into two groups, according to the type of expander used: (I) modified Hyrax and (II) inverted Mini-Hyrax. A pretreatment cone-beam computed tomographic image (T0) was taken as part of the initial orthodontic records and three months after RME, for bone graft planning (T1). Results: In general, there was no significant difference among groups (p > 0.05). Both showed a significant transverse maxillary expansion (p < 0.05) and no significant forward and/or downward movement of the maxilla (p > 0.05). There was greater dental crown than apical expansion. Maxillary posterior expansion tended to be larger than anterior opening (p < 0.05). Cleft and non-cleft sides were symmetrically expanded and there was no difference in dental tipping between both sides (p > 0.05). Conclusions: The appliances tested are effective in the transverse expansion of the maxilla. However, these appliances should be better indicated to cleft cases also presenting posterior transverse discrepancy, since there was greater expansion in the posterior maxillary region than in the anterior one.
