Prevalence of Palato Radicular Groove in Maxillary Lateral Incisors

Palate radicular grooves, also called Palato gingival grooves or radicular lingual grooves are developmental anomalies in which an infolding of the inner enamel epithelium and Hertwig's epithelial Root sheath create a groove that passes from the cingulam and extend varying distances apically on to The root. The purpose of this study was to determine the prevalence of palato gingival groove in maxillary lateral incisors. 100 patients of age ranged between 15-30 years. Patients with missing or crowned lateral incisors were excluded from the study. All lateral incisors were carefully examined for the presence, extension of palato gingival groove. The prevalence of palato gingival groove was 20%. They were found to be 12.5% as coronal groove and 7.5% as an apical groove. Bilateralism was found to be 45%, 52% for coronal and 48% for apical grooves. It was concluded that prevalence of palate gingival groove is high .
