Orthodontic-induced external apical root resorption is one of the idiopathic phenomena as an effect, with force generated through mechanotherapy as the cause and the biological tissues with their diversified variations as witness. It is also classified as iatrogenic as a result of indeterminate application of orthodontic forces with subconscious appreciation of the existing underlying conditions. Numerous factors were identified to relate to this irreversible pathologic condition, but none were proven scientifically. Genetics and salivary markers have proved the reliability with time, but the application became insignificant limiting mostly to the research field. Different assessment methods were also identified to clinically diagnose it both subjectively and objectively. Mostly, it is identified through routine radiographic stage records like orthopantomogram or certain prediction radiographs for root resorption probability assessment like in this case. This case report discusses one such encounter which was experienced after stage 1 and 2 mechanics involving quite a few teeth. Considering the biotype of the individual and tooth morphology, the ongoing treatment was terminated and recovery measures were briefed to uplift the self-esteem of the individual. Furthermore, the prognosis is compromised to be very poor with unpredictability to any other treatment modalities.
正畸诱导的根尖外吸收是一种特发性现象,其起因是机械治疗产生的力,而生物组织的多样变化则是见证。由于在未充分认识现有潜在状况的情况下不确定地施加正畸力,它也被归类为医源性。已确定许多因素与这种不可逆的病理状况相关,但均未得到科学证实。遗传学和唾液标志物已随时间证明了其可靠性,但应用范围有限,主要局限于研究领域。还确定了不同的评估方法用于主观和客观地临床诊断它。大多数情况下,它是通过常规的放射影像学记录(如全景曲面断层片)或某些用于评估牙根吸收可能性的预测性放射片(如本例)来确定的。本病例报告讨论了在涉及多颗牙齿的第一阶段和第二阶段力学治疗后发生的这样一次遭遇。考虑到个体的生物类型和牙齿形态,终止了正在进行的治疗,并简要介绍了恢复措施以提升个体的自尊心。此外,预后被认为非常差,对任何其他治疗方式都具有不可预测性。
