Horizontal root fracture in the apical third: case report

ABSTRACT This article presents a clinical case of horizontal root fracture, in an adult patient, male, in the apical third, due to the practice of sports, which, along with other factors, has led to pulp necrosis. Initially, the patient sought emergency care, and then he underwent treatment by endodontics, using calcium hydroxide between sessions. After a monitoring period, root canal obturation was performed and the tooth is clinically and radiographically stable 2 years after the trauma. In this case, monitoring is long-lasting, divided into 12-month periods for 10 years, with clinical and radiographic evaluation. Dental fracture in children and teenagers from 10 to 14 years is very common, especially during the practice of sports and recreation activities. It is expected that young male individuals have greater propensity to damage their teeth than young female individuals. Maxillary central incisor is the tooth most commonly involved, and it often evolves to pulp necrosis after trauma.

摘要 本文报道1例成年男性患者发生于根尖1/3段的水平型根折病例，该病例由运动损伤诱发且合并其他致病因素，最终导致牙髓坏死。患者最初就诊于急诊，随后接受牙髓治疗（endodontics），两次诊疗间隔期间使用氢氧化钙（calcium hydroxide）进行干预。经过一段观察期后，实施了根管充填术，外伤后2年患牙的临床及影像学检查均处于稳定状态。本病例的随访周期较长，计划以12个月为一个周期开展长达10年的随访，每次随访均进行临床与影像学评估。10至14岁的儿童及青少年牙折发生率较高，尤其在运动及休闲活动中更为常见。研究显示，年轻男性群体相较于年轻女性群体，更易发生牙体损伤。上颌中切牙是最常受累的牙位，且外伤后常继发牙髓坏死。
