Abstract

Introduction: One of the most common causes of impacted permanent anterior teeth is the presence of Supernumerary teeth (ST). which have an impact on developing teeth, and dental arches as well.
Aim/ Objective: To evaluate the prevalence, distribution, characteristics, and complications of ST in maxillary and mandibular anterior region in a sample of Egyptian children.
Methods: Clinical and radiographic examination of 189 non-syndromic Egyptian children who were diagnosed with ST. Two pediatric dentists with over 10 years of experience performed data analysis. The Age, sex, number, morphology, orientation, and position of ST were recorded, as well as complications.
Results:
A total of 248 ST were diagnosed in 189 children with ages ranging from 6-14 years. Males were more frequently affected than females in the ratio of 1.7:1 . Out of the 284 ST, 53% were conical, 32% were tuberculate and 15% were supplemental, 14% were inverted, and 95% were fully impacted. The number of ST was one in 65%, two in 31%, and three in 4%. The main complication was delayed eruption in 80%, diastema in 11%, and crowding in 6%.
Conclusion: Prevalence of ST in a sample of Egyptian children was 0.3%. Most of the ST were diagnosed at age 6 -11 years. Most of them were single, vertically impacted in the palatal maxillary region, both conical and tuberculated in shape. Males: female ratio is 1.7:1
