Abstract
ObjectiveThis study aims to estimate the prevalence of congenitally missing lateral incisors in a sample of 2662 dental patients in Palestine.MethodsA total of 2662 digital panoramic radiographs were retrospectively examined for the presence of congenitally missing permanent lateral incisors. The radiographs were obtained from the archival records of patients attending a local dental center at the city of Nablus in Palestine.ResultsThe prevalence of missing lateral incisors among the examined population (n = 2662) was found to be 1.91%. Unilateral agenesis accounted for 66.6% of the total cases that showed at least one missing lateral incisor. Around 79% of the unilateral cases were on the left side while 21% were on the right side. Bilateral agenesis accounted for 33.3% of 34 cases that had at least one congenitally missing permanent maxillary lateral incisor.ConclusionThe prevalence of missing maxillary lateral incisors in this study population was 1.91%) which was within the range reported in different populations.
