Abstract

Root resorption is a pathological process involving loss of hard dental tissues. It may occur as a consequence of dental trauma, orthodontic treatment, and bleaching, and occasionally it accompanies periodontal disease. Although the mechanism of resorption process is examined in detail, its etiology is not fully understood. Wide open apical foramen is more difficult to manage and the root canal may often overfill. In this report we present two cases of root resorption and describe means for its clinical management. We conclude that useful measure of a success or failure in managing root resorption is the persistence of the resorption process. It is a clear sign of an active ongoing inflammatory process and shows the clinical need for retreatment.

Highlights

In healthy organism, the outer and inner walls of dental root are protected by a thin antiresorption barrier
Periapical inflammation is often discussed as possible cause of a radicular external resorption
The severity of resorption is proportional to the duration of the periapical inflammation

Summary

Introduction

The outer and inner walls of dental root are protected by a thin antiresorption barrier. In a more recent study Tsesis et al [8] investigated the prevalence of root resorption in Middle Eastern population, finding that almost 29% of teeth were affected. The most common type of resorption was related to pulpal infection. Some cases of external resorption can be classified as idiopathic with unknown or unproven causality. It occurs as a solitary or multiple form. Internal root resorption originates in the inner wall of the root canal system. The calcium hydroxide treatment is discontinued when a continuous periodontal ligament space becomes visible radiographically This process may take up to 6–12 months [19]. Proper threedimensional obturation of the root canal provides satisfactory seal as it can be condensed into the undercutting areas of an internal resorption lacuna [20]
