The teeth are formed during intrauterine life (i.e., gestation) during the odontogenesis stage. During this period, the teeth move until they enter the oral cavity. This course covers various stages of dental development, namely, initiation, proliferation, histodifferentiation, morphodifferentiation, and apposition. The talon cusp is an anomaly that occurs during morphodifferentiation, and this anomaly may have numerous adverse clinical effects on oral health. The objective of this study was to report a case of "Talon Cusp Type I" and to discuss diagnostic methods, treatment options for this anomaly, and the importance of knowledge of this morphological change among dental professionals so that it is not confused with other morphological changes; such knowledge is required to avoid unnecessary surgical procedures, to perform treatments that prevent caries and malocclusions as well as enhancing aesthetics, and to improve the oral health and quality of life of the patient.
牙齿在子宫内生活(即妊娠期)的牙胚发生阶段形成。在此期间,牙齿移动直至进入口腔。本课程涵盖牙齿发育的各个阶段,即起始、增殖、组织分化、形态分化和矿化。畸形中央尖是在形态分化过程中出现的一种异常,这种异常可能对口腔健康产生许多不良临床影响。本研究的目的是报告一例“Ⅰ型畸形中央尖”病例,并讨论该异常的诊断方法、治疗选择,以及牙科专业人员了解这种形态变化的重要性,以免与其他形态变化相混淆;需要这种知识来避免不必要的外科手术,进行预防龋齿和错牙合畸形以及增强美观的治疗,并改善患者的口腔健康和生活质量。
