Abstract

Svrha istraživanja bila je utvrditi promjene prednje i stražnje visine lica te njihovih proporcija između desete godine života i odrasle dobi u ispitanika normalne okluzije hrvatske populacije. Istraživanje je provedeno na uzorku od 199 rentgenograma ispitanika podijeljenih u pet dobnih skupina. Precrtavanjem rentgenograma na proziran papir mjerile su se sljedeće varijable: s-go = stražnja visina lica; n-m = prednja visina lica i s-go/n-m = proporcija prednje i stražnje visine lica. Stražnja visina lica (s-go) u cjelokupnom uzorku pokazuje porast od 10,72 mm između desete godine i odrasle dobi (12,9%). Prednja visina lica (n-m) raste sa 112,99 mm na 123,49 mm što ukupno iznosi 10,5 mm ili 8,5%. Odnos prednje i stražnje visine lica pokazuje lagan porast od 63,97 do 67,14% između najmlađe i najstarije dobne skupine. Sve mjerene vrijednosti više su u muških ispitanika.The purpose of this study is to determine the changes in the posterior and anterior facial heights as well as in their proportions that occur between the age of 10 years and adulthood in subjects with normal occlusion in Croatian population. The investigation was carried out on 199 lateral cephalometric radiographs of patients divided into five age groups. The radiographs were traced and the following measurements have been derived : s-go = posterior face height; n m = anterior face height and s-go/n-m % = face height ratio. Posterior face height dimensions (s-go) in total sample showed an increase of 10,72 mm between 10 years of age to adulthood (12.9%). The mean anterior face height (n-m) value in whole sample increases from 112,99 to 123,49 mm which is 10,5 mm or 8,5 %. Anterior-posterior face heights ratio showed slight increase from 63,97 to 67,14 % from the youngest to the oldest age group. All measured face dimensions are higher in males than in females in all groups
