Study of the incidence of radicular grooves in maxillary incisors.
The purpose of this investigation was to determine the incidence of radicular grooves in the upper incisors of 642 patients from the region of Ribeirão Preto, SP, Brazil. Radicular grooves, present in 3.9% of the patients, were found mainly on the lingual surface of the maxillary lateral incisor (3.0%). The maxillary central incisors showed radicular grooves on both the buccal and lingual surfaces with an incidence of 0.9%. It was not possible to relate the incidence of these grooves with race (white and negro) or with sex.
