Abstract

Introduction
This report describes a case of Internal Root Resorption (IRR) in the mandibular first molar of a 14-year-old patient undergoing orthodontic treatment. IRR is a rare and largely asymptomatic process in which dentin tissue in the pulp chamber and root canal is resorbed due to odontoclast activity and is often detected incidentally on radiographs.
Case presentation
The present case was a patient with good oral hygiene and, except for deep probing at one point on the buccal surface of the tooth in question, other probing areas were normal, indicating concurrent periodontitis. CBCT imaging studies confirmed the presence of IRR in the distal root of tooth number 30 as well as External Surface Resorption (ESR). Due to pulp necrosis and the presence of a combined endo-periodontium lesion, root canal therapy was performed to manage the condition. After treatment, the patient was asymptomatic and follow-up images showed a decrease in peri-root radiolucency and improvement in periodontal conditions, including normal probing depth.
Conclusions
In the present case, the internal resorption in tooth number 30 was probably related to orthodontic treatment. This association has been previously reported in several studies that have shown that orthodontic forces can in certain cases initiate or exacerbate the internal resorption process, especially if the pulp is already damaged.
