Abstract

The upper canine teeth exhibit significant sexual dimorphism, making them frequently used in gender identification in forensic odontology. The measurement of the inter-canine width can be performed using conventional methods, such as a digital caliper, or modern methods using an intraoral scanner. The intraoral scanner offers higher accuracy and easier data storage; however, no studies have compared the inter-canine width of the upper jaw using both methods. This study measured the inter-canine width of the upper jaw on 80 jaw models using both instruments, with each measurement performed three times per instrument. The measurement results were analyzed using SPSS, with Intraclass Correlation Coefficient (ICC) for agreement, Kolmogorov-Smirnov for normality, and Independent T-test for significance. The ICC results showed good agreement (0.892), and the Independent T-test revealed no significant difference (p = 0.598). It can be concluded that there is no significant difference between the measurement of the upper inter-canine width using the intraoral scanner and the digital caliper.

Abstract

Objectives: This research aims to determine the variation in the distance of maxillary posterior tooth roots to the maxillary sinus. Materials and Methods: This research employed a descriptive observational design using 68 samples of CBCT radiographs of individuals aged 20–40 years from Dental Radiology Installation of Dental & Oral Hospital, Faculty of Dentistry, Universitas Trisakti. The distance assessed in this study is the shortest vertical distance from the apices to the maxillary sinus floor of all roots in first premolars, second premolars, first molars and second molars. The measurements were performed using i-Dixel 2.2 software (Morita-Japan). Results: The result showed the mesiobuccal root of the second molar was the closest to the maxillary sinus, with a mean distance of -0.24 ± 1.23 mm. Conversely, the buccal root of the first premolar was the farthest, with a mean distance of 4.72 ± 3.11 mm. Conclusion: The proximity order of roots relative to the maxillary sinus, from closest to farthest, is as follows: mesiobuccal root of the second molar, distobuccal root of the second molar, palatal root of the first molar, distobuccal root of the first molar, mesiobuccal root of the first molar, palatal root of the second molar, palatal root of the second premolar, the single root of the second premolar, buccal root of the second premolar, palatal root of the first premolar, the single root of the first premolar, buccal root of the first premolar. Keywords: Cone Beam Computed Tomography, maxillary sinus, posterior teeth roots.
