BACKGROUND/PURPOSE: Pre-eruptive intracoronal resorption (PEIR) is usually detected accidently in radiographs. However, treatment modality is still not reported systematically. The current study aimed to conduct a systematic review of the treatment modality of PEIR case reports and to report a case on the preservation of a vital pulp with surgical exposure in permanent maxillary canine.
We systematically searched case reports from PubMed/MEDLINE, EMBASE, and Web of science databases. The treatment modality, suspected etiology, and follow up periods were collected from each study and reviewed by two authors independently.
The initial search identified 100 studies. After the title/abstract screening, 37 articles received a full-text reading; and finally, 24 articles (29 patients and 37 affected teeth) were selected for the final review. Among the 24 unerupted teeth, surgical opening and restoration treatment of PEIR was chosen as a high priority for treatment options (n = 9, 36%). Among the 13 erupted teeth, restoration was applied for the prevention such as developing in size and fracture (n = 4, 31%).
According to this systematic review, treatment modalities were based on the progressive nature of the lesion size and eruption state to establish the optimal approach for each patient. Clinicians should take into account the eruption status, lesion progression, the size of the lesion, and the degree of pulp involvement.
背景/目的：牙冠内吸收（PEIR）通常在X线片检查时偶然发现。然而，其治疗方式仍缺乏系统报道。本研究旨在对牙冠内吸收病例报告的治疗方式进行系统综述，并报告1例通过手术暴露保存上颌恒尖牙活髓的病例。
我们系统检索了PubMed/MEDLINE、EMBASE和Web of science数据库中的病例报告。从每项研究中收集治疗方式、可疑病因和随访时间，并由两位作者独立进行综述。
初步检索共识别出100项研究。经标题/摘要筛选后，37篇文章进入全文阅读；最终，24篇文章（29例患者，37颗患牙）被纳入最终综述。在24颗未萌出的牙齿中，牙冠内吸收的手术开窗和修复治疗被列为首选治疗方案（n = 9，36%）。在13颗已萌出的牙齿中，采用修复治疗预防牙齿大小改变和折断（n = 4，31%）。
根据本系统综述，治疗方式应基于病变大小的进展情况和萌出状态，为每位患者制定最佳治疗方案。临床医生应考虑牙齿的萌出状态、病变进展、病变大小以及牙髓受累程度。
