A palato-radicular groove (PRG) is a developmental anomaly primarily found in the maxillary lateral incisors. It is a potential communication path between the root canal and the periodontium that decreases the survival prognosis of the affected tooth, therefore compromising the stability of the dental structure in the oral cavity. The aim of this case report is to present an original technique where a PRG was treated by means of intracanal disinfection, PRG sealing with glass ionomer, replantation with intentional horizontal 180 degree rotation of the tooth, and an aesthetic veneer placed to provide adequate tooth morphology. The clinical and biological benefits of this novel technique are presented and discussed.
腭根沟(PRG)是一种主要在上颌侧切牙中发现的发育异常。它是根管与牙周组织之间的潜在连通路径,会降低患牙的存活预后,从而损害口腔中牙齿结构的稳定性。本病例报告的目的是介绍一种原始技术,该技术通过根管内消毒、用玻璃离子封闭PRG、牙齿有意水平旋转180度再植以及放置美学贴面以提供适当的牙齿形态来治疗PRG。本文展示并讨论了这种新技术的临床和生物学益处。
