Abstract
Internal root resorption has been reported as early as in the early of the 18<sup>th</sup> century. It presented with the classic oval-shaped enlargement of the root canal area. It can be classified as either inflammatory or replacement. Non-surgical root canal treatment for this diagnosis may present with an inimitable operative encounter. Clinical considerations: A non-surgical root canal retreatment had been attempted and discussed in this paper. The attempt has proved to give more time for the tooth to be functional in the patient mouth. Conclusions: The reduction from 8-mm to 4-mm in pocketing depth, resolving of periapical lesion and no signs and symptoms at the 6-months review provided a favorable outcome to once a hopeless tooth.

The typical diagnosis of internal root resorption is predominantly founded during routine radiographic findings and complementary evidence established from the patient’s history and clinical findings [11]

Summary
Dated in the 1830, root resorptions have been declared as an insurmountable endodontic dilemma [1]. Internal resorption is once considered rare in permanent teeth. It is usually characterized by oval-shaped enlargement of the root canal space [2]. Many authors have explain the aetiology [3, 4], in addition to clinical manifestations [3, 5] and the histologic and radiographic findings [3, 6, 7] together with the management of the pathological resorptive process [4, 5] of internal root resorptions. The typical diagnosis of internal root resorption is predominantly founded during routine radiographic findings and complementary evidence established from the patient’s history and clinical findings [11]
