Abstract

Hipodoncija predstavlja kongenitalni nedostatak zuba i jedna je od najučestalijih kraniofacijalnih anomalija kod ljudi. Pojam hipodoncija se odnosi na nedostatak do 6 zuba. Oligodoncija se odnosi na nedostatak više od 6 zuba, dok anodoncija označava nedostatak svih zuba u čeljusti. Najnovija istraživanja ukazuju na to da su u etiologiju nastanka spomenutog stanja uključeni patologija genetske regulacije razvoja zuba, ali i činitelji okoliša. Hipodoncija se može pojaviti u sklopu prepoznatih sindroma poput Downovog sindroma ili ektodermalne displazije, ali i izolirano, nesindromski. Hipodoncija je mnogo učestalija u trajnoj denticiji nego li u mliječnoj denticiji sa stopom pojavljivanja od 3.5% do 6.5%, ovisno o spolu ili etičkoj pripadnosti. Najčešće nedostaju donji drugi pretkutnjaci i gornji bočni sjekutići. Uz hipodonciju često pronalazimo karakteristične kliničke značajke poput mikrodoncije zuba, transpozicije zuba trajne denticije, ektopične trajne zube i infraokluziju mliječnih kutnjaka. Liječenje ovog stanja uključuje otvaranja, zatvaranje i preraspodjelu praznog prostora u koji bi trebao niknuti zub koji nedostaje. Nakon toga je uglavnom potrebna protetska ili implantoprotetska sanacija, autotransplantacija zuba ili restaurativno preoblikovanje krune zuba koji je pomaknut u prazan prostor.

Abstract (english)

Hypodontia or the congenital absence of teeth is one of the most prevalent craniofacial malformations in humans. The term hypodontia refers to the absence of six or fewer teeth. Oligodontia refers to the lack of at least six teeth while anodontia is defined as the absence of all teeth. The most recent (clinical) studies suggest that the aetiology of the previously described condition involves not only genetic regulation of tooth development, but also environmental factors. Although hypodontia is a common recognizable trait in conditions such as Down‘s Syndrome and ectodermal dysplasia, it can also occur as an isolated nonsydromic trait. The prevalence of hypodontia, which is much more common in permanent than in primary dentition, ranges from 3.5 to 6.5 % depending on the sex and ethnicity ( of the population studied). The most commonly missing teeth are the maxillary second premolars and mandibular lateral incisors. Other clinically relevant traits include microdontia, permanent teeth transposition, ectopic permanent teeth and infraocclusion of primary molars.
The treatment options of this condition involve opening, space closure and redistribution of the missing tooth space. The procedures that follow are prosthetic and implantoprosthetic treatment, autogenuous tooth transplantation or the dental crown restoration of the tooth shifting into an empty space.
