背景:牙齿形状的异常导致需要牙科专家介入的各种临床牙科病症。早期诊断和早期干预可以恢复接近正常的牙列和美学。所以,本研究旨在确定不同年龄段和性别差异中常见的牙齿形状异常及其各种亚型。
方法:对3,000例男性和女性比例相等的病例进行了回顾性牙科铸模和X光片评估。仅年龄范围为10至40岁的病例被纳入研究。评估牙齿形状异常是否存在Gemination,聚变,塔伦尖点,窝点逃避,carabelli的尖端,凹窝,牛磺酸症,和撕裂并记录。
结果:共发现538例(17.9%)牙齿形状异常,其中男性288例(19.2%),女性250例(16.6%)。发现扩张是最常见的(9.2%)牙齿形状异常,其次是牛磺酸症(3.7%),塔隆尖点(2.23%),和carabelli的尖端(1.4%)。大多数形状异常显示男性偏爱。在10至≤25岁的年轻年龄组中,大多数牙齿形状异常的患病率更高,因为它与年龄无关,但在该年龄组进行治疗时仍然很重要。
结论:完全了解印度形状异常的趋势和模式是非常必要的。它将指导牙科医生根据现有的普遍异常情况制定治疗计划。
BACKGROUND: Dental anomaly of shape leads to various clinical dental pathologies requiring the intervention of a dental specialist. Early diagnosis and intervention in earlier stages can restore a near-normal dentition and esthetics. So, the present
study was undertaken to determine the prevailing dental anomalies of shape and its various subtypes in various age groups and gender variations.
METHODS: Retrospective dental casts and radiographs were evaluated in 3,000 cases consisting of an equal proportion of males and females. Only cases with an age range from 10 to 40 years were included in the
study. Dental anomalies of shape were evaluated for the presence of Gemination, fusion, talon cusp, dens evaginates, the cusp of carabelli, dens invaginatus, taurodontism, and dilacerations and recorded.
RESULTS: A total of 538 (17.9%) cases were found to have dental anomalies of shape which included 288 (19.2%) males and 250 (16.6%) females. Dilaceration was found to be the most common (9.2%) dental anomaly of shape followed successively by taurodontism (3.7%), talon cusp (2.23%), and the cusp of carabelli (1.4%). Most of the shape anomalies showed male predilection. A higher prevalence of most dental anomalies of shape was found in the younger age group of 10 to ≤25 years as it is not linked with age but still has got importance to know while the treatment is carried out in this age group.
CONCLUSIONS: It is quite imperative to have complete knowledge of trends and patterns of shape anomalies in India. It will guide dental practitioners to formulate a treatment plan on the basis of existing prevailing anomalies.
