Introduction: The teeth have many developmental disturbancesvariations, it may be variations in number, sizeor inshape, and one of this disturbance is supernumerary teeth that it is a developmental disturbance in number. Supernumerary teeth is may be defined as any excess of the usual configuration of number of teeth or tooth substance in of twenty deciduous, and thirty-two permanent teeth. 1. The most area that involving in this anomaly isthe anterior maxilla, followed by the mandibular premolar region. 2. It can occur in both the primary and the permanent dentitions,until now the causes of the supernumerary are not completely understood, although there are some theories. The most acceptable one is the localized and independenthyperactiveof the dental lamina which presumably leads to the formation of additional tooth germ. It canresult from many factors, genetic or environmental, there are two morphologictypes of supernumerary teeth, supplemental and rudimentary. Several studies have investigated the prevalence of the supernumerary teethSaudi Arabiaone of them found the in Jazan is 0.50 % among 2,393children 4-12 years old. Supplemental refers tosupernumerary teeth that closely resemble normal teeth in shape and size Rudimentarysupernumerary teeth bear little resemblance tonormal teeth in size or shape and include conical,tuberculate, and molar form types 4 &5. Complications associated with the presence of supernumerary teeth include enlarged follicular sacs, cystic degeneration, nasal eruption, malposition of adjacent teeth, over retention of primary teeth, delayed eruption of permanent teeth, loss of space, impaction, diastema, loss of vitality, and root resorption 4,5,6,7. Supernumerary teethare characteristically found in cleidocranialdysostosis, Gardner’s syndrome, orofacial digitalsyndrome 4, Rothmund-Thomson syndrome,hypertelorism-Hypospadias syndrome, and cleftpalate 4,i5, 8.
