Pak Oral Dental J Jan ;39(1):82-4.

Embryological hazards are frequently seen in the region of maxillary incisors. PGG is a growth defect of the tooth present on the palatal surface of maxillary anterior teeth. In this anomaly, a groove begins in the central fossa, extends across the cingulum, and extends gingivally with varying depths and distance. The aim of this study was to evaluate the frequency of PGG in the maxillary central and lateral incisors of the patients visiting Khyber College of Dentistry, Peshawar. A total of 250 patients were examined at Khyber College of Dentistry, Peshawar for the palatogingival groove visually. Palatogingival groove was present in 7.6% of central incisors and 13.4% of lateral incisors.
