Abstract
Background
The anterior tooth has various nonmetric traits, which vary between different populations. These traits serve as a valuable source of information for anthropologists and forensic odontologists, and some of these traits exhibit sexual dimorphism.
Methods
Dental casts of 163 patients in South Indian population, 69 males and 93 females, were scanned and digitized, and the anterior tooth traits of shoveling, double-shoveling, curvature, peg-lateral, and tuberculum dentale were observed and graded according to the scoring system by Arizona State University Dental Anthropology System (ASUDAS). Palatogingival groove was noted as present or absent.
Results
The prevalence of shoveling in the mandibular central incisor was 15.9 %–18.3 % and shoveling in the maxillary central incisor was 20 %–26.9 %. Shoveling was found in 24.7 %–28.6 % in the maxillary lateral incisor. The curvature of the maxillary central incisor was seen in 24.3 %–28 %. Tuberculum dentale was seen in 38.6 %–43 %. Double shoveling of the maxillary central incisor was seen in 7.1 %–7.5 %. Peg lateral was found in 8.6 % of males and 1.1 % of females, exhibiting significant gender differences. Palatogingival groove was present in 9.7 %–11.6 %. Sexual dimorphism in relation to shoveling pattern of lateral incisor and increased prevalence of palatogingival groove on the left side was noted.
Significance
Apart from shoveling, other anterior nonmetric traits have not been studied widely in different populations. These traits, which show variations, and their prevalence have been recorded in this study.
期刊介绍:
Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
