Endodontic Treatment in Submerged Roots: A Case Report

Alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction. while the extent and pattern of resorption is variable among individuals, there is a progressive loss of ridge contour as a result of physiologic bone remodeling. even today, with best modalities of tooth preservation, there is a group of elderly individuals who do not benefit from modern preventive practices and who now present a dilemma in terms of maintaining the masticatory apparatus necessary for nutrition. even with excellent dental care, such patients experience abrasion of the natural tooth crowns with age, and embedded roots are left within the alveolar bone. according to old concepts of dental care, extraction of these roots would have been recommended, but today’s goal of excellence in endodontics dictates otherwise.we report a case in which vital and non-vital root submergence was carried out to prevent alveolar ridge reduction.
