Diverse morphological tooth deformities are found in various shapes, textures, and prevalence. They can be sporadic or syndromes, nutritional, environmental, genetic, and ethnic related. Most of these tooth-born (ie, patient born with the deformation) deformations (eg, shovel-shaped incisors, tuberculum Carabelli, variations in number and shape of cusps, dens invaginatus, taurodontism) have been extensively investigated.1–10 Labial-cervical-vertical groove (LCVG), which starts on the cervical enamel and extends to the radicular surface, has also been described as a notch.11–17 It is assumed that this malformation is a developmental anomaly in which an infolding of the enamel organ and Hertwig’s epithelial root sheath create a groove on the labial surface of permanent maxillary incisors.11 LCVG runs vertically from the crown surface to the root, starting at the enamel on the crown cervix and extends apically, crossing the cementoenamel junction and resembling a short furrow.
