Introduction: One of the identification methods in forensic odontology is to estimate age through tooth characteristics. With age, odontoblast cells that line the pulp cavity will continue the process of secondary dentin deposition at a lower rate. Generally, maxillary canines are teeth that can survive in the oral cavity until old age and are less likely to wear out. This study aimed to determine the correlation between human chronological age and the dentin volume of the maxillary canines using CBCT radiographs. Methods: An analytic study of the Pearson correlation test was conducted on 114 samples of CBCT radiographs of the maxillary canines from the Radiology Unit of the Rumah Sakit Gigi dan Mulut, Faculty of Dentistry, Universitas Padjadjaran. The inclusion criteria for this study were canines with closed apex, no caries, no attrition, no restorations, no orthodontic treatment, and generally good health. Maxillary canine dentin volume was measured using the application ITK-SNAP version 3.8.0. The results of dentin volume were analyzed using the Pearson correlation test using SPSS IBM Statistics 25. Results: Pearson correlation analysis showed the correlation coefficient value (r= 0.270 and (r = 0.427) for the male and female samples, respectively. Conclusion: The correlation between chronological age and maxillary canine dentin volume in this study was not strong enough to be used as a single parameter in the age estimation method. Future research is expected to expand the sample size with a homogenous age distribution to obtain more consistent and accurate results.Keywords: age estimation; dentin volume; maxillary canines; ITK-SNAP; CBCT.

Background: the ability to mentally manipulate 3D objects and understanding the relationships between structures is essential in many fields of medical and dental specialties. This scoping review of the literature on spatial ability in medical and dental education was conducted to provide a map of the literature and identify where gaps still exist for future research.Methods: the study was conducted using a scoping review method with guidelines from the Arksey and O'Malley framework to identify literatures related to the research topic. Searches was performed from February to May 2021 in PubMed, Cochrane, CINAHL and Google Scholar using keywords related to spatial ability, medical education and dental education. Literatures was also identified using snowballing technique. PRISMA-ScR analysis for study selection was performed.Results: fifteen articles were selected for review. Spatial ability correlates with performance in studying anatomical knowledge of medicine and dentistry, and surgery. 3D anatomical models are more effective when conveying complex spatial relationships than traditional 2D models. The Mental Rotation Test (MRT) is the most widely used test for measuring spatial abilities. The results of the measurement of spatial ability showed the superiority of males over females.Conclusion: spatial ability and learning in medical and dental education provide mutual benefits for both aspects. Additional spatial abilities module may be added to medical and dental education curricula to improve learning success
