PURPOSE: This study aimed to analyze the relationship between self-perceived dental esthetics and the selected esthetic mathematical proportions. MATERIALS AND METHODS: Descriptive cross-sectional study was conducted among 48 dental students who fit into the inclusion criteria. The subjects rated their self-perceived dental esthetics based on the given Likert scale. Standardized portrait photographs of each subject were taken and the mesiodistal measurements of the maxillary anterior teeth were measured using a graphic editing software. The golden proportion, golden percentage and RED proportion in maxillary anterior teeth were then calculated. RESULTS: Most subjects were pleased with the size, form, and color of their maxillary anterior teeth. Only 2.1% of the maxillary canines and 10.4% of the left maxillary lateral incisors complied with the golden proportion. The maxillary lateral incisors demonstrated its occurrence to golden percentage. For the RED proportion, 29.2% of the left maxillary teeth and 16.7% of the contralateral teeth complied with the proportion. Self-perceived dental esthetics and the occurrence these mathematical proportions have no association. CONCLUSION Within the limitations of the study, it can be concluded that most subjects were satisfied with their self-perceived dental esthetics. Only a small percentage of the subjects having their natural dentition coincide with the golden proportion, golden percentage and RED proportion with a higher percentage occurring on the RED proportion. Hence, the mathematical proportions do not represent the naturally occurring dentition. These mathematical proportions can serve as a guide and the perceived teeth width can be customized accordingly.

EXPLORING THE USES, STERILIZATION AND STORAGE PROTOCOLS OF EXTRACTED HUMAN TEETH FOR RESEARCH ADVANCEMENTS: A SCOPING REVIEW Extracted human teeth (EHT) have long served as invaluable specimens in dental research, offering valuable insights into dental science and biomaterials. This scoping review aims to document the current uses of EHT in dental research and to identify the sterilisation and storage protocols. The study employed scoping review methods. Relevant databases (PubMed, Scopus, and Science Direct) were searched using the terms “extracted human teeth” and “in-vitro” to identify articles for inclusion. The most recent articles published over five years (2019-2023) and those in English were included. Two reviewers independently conducted the selection process, and the decision was consensually made. A descriptive statistical assessment was performed to analyse the studies involving EHT and the sterilising and storage solutions used. A total of 105 articles were reviewed: Endodontology (32%), Dental Materials (24%), Conservative Dentistry (20%), Prosthodontics (8%), Regenerative Therapy (6%), Oral Biology (5%), Orthodontics (4%), and Periodontology (3%). 71% of the reviewed papers did not report the sterilising and storage methods for EHT. When reported, sodium hypochlorite was most commonly used (15%). However, the concentrations and immersion time in the sterilising solutions were inconsistent. The most frequently used storage solutions to keep EHT from dehydration are saline (11%) and distilled water (10%). In conclusion, extracted human teeth continue to be extensively utilised in dental research. Nonetheless, the reporting and standardisation of sterilisation and storage methods are notably inadequate. A standardised guideline for sterilising and preserving extracted human teeth for various types of research is essential to mitigate variability and promote result uniformity. There is a stark absence of consensus regarding the optimal procedures for storing and sterilising EHT, even when used for the same laboratory investigations and different types of dental research.
