Abstract:
Introduction.
Supernumerary teeth(ST) are found in both temporary and
permanent dentition. The prevalence rate varies from
0.04% to 2.29%. ST are usually associated with other dental
abnormalities, such as delayed eruption, ectopic eruption,
periapical resorption of permanent teeth and the formation
of follicular cysts, etc. Clinical manifestations of some
syndromes may be associated with the presence of ST.
Aim of the study. The study of the epidemiology and
clinical manifestations of ST in a group of children and
adolescents.
Material and methods. A visual and radiological
examination was performed on 576 patients aged 6 to18
years who met the criteria for inclusion in the study.
Statistical analysis was performed. The subject of the
study was"ST".
Results. 576 children and adolescents aged between 6
and18 from the University Dental Clinic of the Republic of
Moldova were examined clinically and radiologically.
"ST"was observed in18 patients (3.1%). More frequently, the
dental anomaly was observed in the upper jaw - 88.9%, and
only in 11.1% of cases it was detected in the lower jaw. The
gender distribution did not show any major differences. The
anomaly was diagnosed in 55.6% of boys and 44.4% of girls.
One case of ST was detected in cleidocranial dysplasia, and
another case of DS was associated with dental fusion.
Conclusion. The ST frequency in the study group is 3.1%.
The dental anomaly was observed more frequently in the
upper jaw(88.9%), With small differences boys are more
frequently affected than girls. One case of ST was diagnosed
in one syndrome and another was associated with another
dental abnormality.
