The double teeth include gemination and fusion. The congenital missing tooth is the absence of the tooth.
The purpose of this study was to investigate the prevalence of double teeth and congenital missing teeth in preschool children of Iksan city.
The study population consisted of 1.031 children, 569 boys and 462 girls, aged from 17 to 84 months. The double teeth possess a variety of diagnostic and treatment problems. Gemination is the partial splitting of a single bud into two distinct entities that remain joined in a Siamese twin fashion. Fusion is the joining of two buds. Both may be normal, or one may be a supernumerary tooth. Congenital missing is the absence of one or a few teeth.
Twenty three(11 boys and 12 girls) of the 1,031 children had double teeth and 17(8 boys and 9 girls) exhibited congenital missing of teeth. The prevalence of double primary teeth was 2.2%. The prevalence of congenital missing teeth was 1.6%. One subject had double teeth and congenital missing tooth at the same time.
Of the 17 cases of congenital missing teeth, one girl showed it in the maxilla and five boys and six girls had them in the unilateral side of the mandible.
There were no significant differences in the prevalence of double teeth and congenital missing teeth between the boys and the girls.
