The radicular lingual groove (RLG) is a developmental anomaly in which an infolding of the inner enamel epithelium and Hertwig's epithelial root sheath create a groove that passes from the cingulum of maxillary incisors apically onto the root. Radicular lingual grooves can create periodontal and pulpal pathology, but they may be difficult to identify as an etiological factor. This article identifies the diagnostic and treatment modalities for the various forms of RLGs and describes the prognosis that can be anticipated with each treatment modality.
根舌沟（RLG）是一种发育异常，其中内釉上皮和赫特维希上皮根鞘的内陷形成一条从上颌切牙舌隆突向根尖延伸至牙根的沟。根舌沟可导致牙周和牙髓病变，但可能难以确定其为病因。本文确定了各种形式根舌沟的诊断和治疗方法，并描述了每种治疗方法的预期预后。
