38. THE UPPER CENTRAL INCISORS DIMENSIONS AMONG STUDENTS WITH ANTERIOR DIASTEMA IN HCMC UNIVERSITY OF MEDICINE AND PHARMACY
Main Article Content
Abstract
Background: Anterior diastema, which is a gap or space between two or more consecutive teeth, is a common aesthetic treatment problem of people seeking dentists. There are various factors contribute to the formation of anterior diastema, in which tooth size discrepancies being a key concern for clinical practitioners aiming to improve patient aesthetics.
Objective: Our study aims to determine the dimensions and ratio of the upper central incisors among patients with anterior diastema, thereby helping clinicians choose appropriate treatments.
Subject and Methods: This descriptive cross-sectional study was conducted on 2424 first-grade students in University of Medicine and Pharmacy HoChiMinh city. Intraoral scanning in both upper and lower jaws were made from 77 students who had anterior diastema using the Itero 5D Plus scanner. Tooth dimensions (width and height) of the upper central incisors were measured by using Ortho CAD™. All data are analyzed by SPSS 22.0 software.
Results: The incidence of maxillary midline diastema was 3,2%. The study showed that there are significant differences in the width and height of the upper central incisors between males and females (p<0,05), in which the tooth dimension in males are higher than females. Mean values of the width-to-height ratio of upper central incisors is 0,91; which is higher than the standard ratio (0,75-0,85). Among students with maxillary midline diastema, the upper central incisors exhibit abnormal dimensions and tooth size ratios. Specifically, the width and height of these teeth are smaller than normal, and also the width-to-height ratio is greater than the standard ratio, resulting in teeth that tend to be shorter and more square compared to normal teeth.
