Management of a Perforating Internal Resorptive Defect with Mineral Trioxide Aggregate: A Case Report

An Unostentatious Approach for Management of Progressive External Root Resorption – A Case Report

“…Good flow properties, low solubility and tight seal of the root canal due to its slight expansion, hence, no forces exerted on the weakened tooth structure as in comparison to thermomechanical or cold lateral compaction. [15] Despite the serious damage to the root by external root resorption, non-surgical root canal therapy arrested the external root resorption and regenerated the periapical tissue. This is a good result which would like to achieve in any case of External resorption.…”

Management of a Perforating External Infection Related Resorptive Defect: A Case Report

“…In this case, we also preferred repair of the perforation and then root canal filling. The inherent danger with this technique is that the compacting forces required to perform the obturation procedure may displace the external repair material 3 . In this case, repair material was undisturbed because of careful handling.…”

“…The resorption cavity will be then filled in with cementum or bone, according to the type of vital tissue found next to the resorption site (PDL or bone marrow-derived tissue) 1 . However, in cases in which a pathway between the pulp canal space and the periodontal tissues is present, root canal treatment should be followed by repair of the perforation site with a suitable sealing material 3 . Repair may be instituted in one of two ways, either non-surgically by approaching the defect internally through the tooth or surgically by using an external approach through the periradicular tissues 4 .…”

Retreatment of a Mandibular Molar with Chronic Apical Abscess and Internal Root Resorption with the GentleWave® Procedure: A 16-Month Clinical Case Report

“…Internal root resorption is a defect of the internal aspect of the root following loss of the odontoblastic layer, most commonly believed to be a result of chronic inflammation and bacterial invasion of the pulp [1]. During internal resorption, bacteria might reach the pulp through various routes such as lateral canals, carious cavities, cracks and dentinal tubules [2].…”

“…Pain or discomfort may be the chief complaint especially if the granulation tissue gets exposed to oral fluids. However, internal root resorption usually remains clinically asymptomatic and may be detected coincidentally during a routine radiographic evaluation, in which the lesion appears as radiolucent enlargement of the pulpal space [1,4]. Because of its asymptomatic nature, internal root resorption might go unnoticed until the lesion has caused a perforation or symptoms of acute or chronic apical periodontitis [5].…”
