Abstract

INTRODUCTION

Invasive cervical resorption (ICR) is a relatively rare type of ERR (External Root Resorption), in which a localized resorption begins in the cervical area of the tooth, below the epithelial junction and above the ridge crest.

OBJECTIVE

Describe the clinical case of an 11-year-old boy with no dental trauma history, presenting moderate crowding and ectopic eruption of the maxillary right central incisor. He had been undergoing orthodontic treatment elsewhere, and his family was dissatisfied with the results.

DESCRIPTION

A new treatment was indicated, which included rapid maxillary expansion followed by extraction of four premolars. During routine panoramic evaluation, a radiolucid image was detected and a periapical radiograph was requested. At this point, an ICR of the maxillary right central incisor was found. The treatment was cautiously finalized and despite the use of light forces, central incisor was severally compromised by ICR and was therefore extracted.

CONCLUSION

This clinical example discusses the importance of routine radiographs for the early diagnoses of ICR.

摘要

简介

侵袭性根吸收（ICR）是一种相对罕见的 ERR（外部根吸收）类型，其特征为牙齿颈部发生局限性吸收，位于上皮结合下方和牙槽嵴顶上方。

目的

描述一名 11 岁男孩的临床病例，该男孩无牙外伤史，表现为中度拥挤和上颌右侧中切牙异位萌出。他曾在其他地方接受过正畸治疗，但他的家人对治疗结果不满意。

描述

建议进行新的治疗，包括上颌快速扩弓，然后拔除四颗前磨牙。在常规全景评估期间，发现一个透亮影像，并要求拍摄根尖片。此时，发现上颌右侧中切牙发生 ICR。治疗方案被谨慎确定，尽管使用了轻力，但中切牙仍因 ICR 而严重受损，因此被拔除。

结论

本临床病例讨论了常规 X 光片对 ICR 早期诊断的重要性。
