The prevalence of hereditary dental abnormalities in school children

Abstract

Ovim radom utvrđena je učestalost pojedinih dentalnih anomalija u populaciji školske djece celjske regije, koja varira u različitim populacijama, etničkim skupinama i znači specifičnost određene populacije. Pregledano je 513 djece, a ispitivane su abnormalnosti broja, oblika i veličine zubi kao što su: hipodoncija, mikrodoncija, hiperdencija, Carabellijevo svojstvo, invaginacije zubi, lopatasti sjekutići, paramolame kvržice i anomalije u položaju zubi: diastema mediana. Najzastupljenija anomalija u ovoj populaciji je Carabellijeva osobitost s učestalošću od 25,9% zatim invaginacije zubi s 14,8% i diastema mediana s 12,6\u27%. Hipodoncija je prisutna u 2,9%, a mikrodoncija u 3,3% populacije. Ostale anomalije pojavljuju se vrlo rijetko, u manje od 1% populacija. Značajnih razlika u učestalosti prema spolu nema.The aim of this study was to find the prevalence of particular dental anomalies in a population of school children from the area of Celje. This parameter has been found to vary among various population and ethnic groups, thus representing a population-specific feature. A group of 513 children were examined for abnormalities in the number, form and size of teeth, such as hypodontia, microdontia, hyperdontia, Caraibelli’s trait, dental invagination, shovel-shaped incisors, paramolar nodules and position anomalies, e. g. diastema mediana. In our study population, Caraibelli’s trait was found to be most frequent (25.9%), followed by tooth invagination (14.8%) and diastema mediana (12.6%), whereas hypodontia and microdontia were recorded in 2.9\u27% and 3.3% of the population, respectively. Other anomalies were quite infrequently observed, i.e. in less than 1% of the population under study. No significant sex-related difference in the prevalance of anomalies were detected
