 Background and Objectives: The aim of this paper is to describe the application of a newly developed three-dimensional imaging system, Cone-Beam Computed Tomography in the diagnosis and evaluation of supernumerary teeth.Material and Methods: One hundred and eighty-five patients with supernumerary teeth (134 males and 51 females) were included in this study. Patients ranged in age from 6 to 38 years. Supernumerary teeth were detected by clinical examination and conventional radiographs. Moreover, careful investigation for more details was made with the cone beam computed tomography. Supernumerary teeth which were detected with the examinations of the cone beam computed tomography images were analyzed according to the number, location, shape and position.Results: Males were affected more than females in a ratio of 2.6:1. 95 % supernumerary teeth were located in maxilla and 5 % in the mandible. 71.6% of supernumerary teeth were conical in shape. 93.6% supernumerary teeth were impacted and 6.4% were erupted. A total of 198 supernumerary teeth were found to be present in palatal/lingual side and 24 were found on the buccal side. 80.5 % of the patients had one, 18.9 % had two, and 0.5 % had three supernumeraries.Conclusion: Detailed examinations and evaluations of these teeth with Cone-Beam Computed tomography (CBCT) yields accurate 3-dimensional pictures of supernumerary teeth, local dental and bony structures which are very beneficial in terms of proper diagnosis and treatment planning and preventing complications which may occur. Janaki Medical College Journal of Medical Sciences (2017) Vol. 5(1): 5-15

Background: Dental implants are considered the first option to replace missing teeth. Alveolar bone resorption gradually progresses following tooth extraction leading to loss of vertical bone dimension for implant placement. The lateral window approach is the most commonly used procedure to treat vertical bone loss. Objectives: The aim of the present study is to evaluate the lateral wall thickness (LWT) of the maxillary sinus and determine the influence of gender and side on maxillary LWT. Methods: This study involved a cross sectional retrospective study. Cone- beam computed tomography data were collected from 99 patients with a total of 198 maxillary sinuses that met the inclusion criteria. The patient age ranged from 18 to 35 years. On the selected sagittal section, the points of measurement are determined by a perpendicular line at 5 mm from the lowest point of the sinus floor. Measurements were done at four different areas; first premolar (P1), second premolar (P2), first molar (M1), and second molar (M2). Descriptive statistics were used to calculate mean lateral wall thickness for each tooth, and student’s t-test was used to test the effect of gender and side on maxillary LWT. Results: The greatest mean LWT was observed around the left first maxillary molar (2.43±0.82), while the lowest mean LWT was observed around the right second maxillary premolar (1.62±0.61). There was no significant difference in the LWT around any tooth (M1 p=0.56, M2 p=0.92, P1 p=0.14, P2 p=0.19). Conclusion: There was no significant difference in both males and females of the lateral wall thickness in the left and right side of maxillary sinus.
