Prevalence of Tooth Agenesis in Orthodontic Patients at Arab Population in Israel

Introduction: Non-syndromic tooth agenesis has been occasionally described in literature and data available for its prevalence
is rare in Arabs population in Israel. The purpose of the present retrospective radiographic study was to provide data
concerning the prevalence of non-syndromic hypodontia in patients reporting to the Center for Dentistry,Research & Aesthetics,
Jatt, Almothalat, Israel. Material and Methods: Five hundred consecutive patients who met the inclusion criteria were selected
from the records. The radiographic records included at least one clear adequate quality Orthopantomogram (OPG), which was
supplemented when necessary by a periapical radiograph. Results: A prevalence of 2,6 percent hypodontia was seen in the
sample. Conclusions: It was concluded that hypodontia is prevalent in Arabs population in Israel with a 2,6% incidence which
is on the higher limit of the global range (1.6 – 9.6%). However further studies should be conducted on a larger nonorthodontic
sample to determine accurately this incidence of hypodontia.
