Abstract

Gubitak vitaliteta prije završetka rasta i razvoja korijena zuba uzrokuje usporeno odlaganje dentina i zaustavljen razvoj korijena. Nastali korijen je kratak, s tankim i oslabljenim dentinskim stijenkama, dok je apeks širok i bez konstrikcije. Takav zub je smanjene funkcijske vrijednosti i trajnosti.
Direktno prekrivanje indicirano je kod male ekspozicije pulpe, kada se na pulpnu ranu aplicira medikament koji potiče stvaranje dentinskog mostića. Kod veće ekspozicije indicirano je uklanjanje inficirane pulpe (plitka ili cervikalna pulpotomija) i aplikacija medikamenta na preostalu vitalnu pulpu.
Ukoliko je vitalitet izgubljen, indicirana je pulpektomija i apeksifikacija. Apeksifikacija označava medikamentima potaknuto stvaranje kalcifikacijske (ili umjetne) barijere u području širokog apeksnog otvora. Apikalna barijera omogućuje nam završno punjene korijenskog kanala gutaperka štapićima i pastom.
MTA i Ca(OH)2 su materijali koji se najčešće primjenjuju za DPP i apeksifikaciju.
Gubitak zuba neophodno je brzo nadoknaditi zbog višestrukog negativnog učinka. Implantati i klasični mostovi su kontraindicirani zbog nezavršenog skeletnog rasta pa se stoga kao terapijsko rješenje najčešće izrađuju djelomične proteze („žabice“) ili privjesni mostovi.
Preventivnim postupcima onemogućuje se djelovanje čimbenika koji ugrožavaju vitalitet zuba. Poštovanjem uputa o prehrani i održavanju oralne higijene, fluoridacijom zuba i pečaćenjem fisura sprječava se razvoj karijesne lezije, a korištenjem štitnika preveniraju se traumatske ozljede zuba.

Abstract (english)

Vitality loss before the termination of root growth and development causes slow dentin reproduction and delayed root development. This results in a short, thin and weak dentin wall and a wide apex without constriction, which causes reduced worth and persistency.
Small pulp exposition indicates direct pulp capping, in a way that the medicament placed on the pulp exposition causes the creation of a dentine bridge. Large exposition indicates the removal of the infected pulp (partial or cervical pulpotomy) and the application of a medicament on the remaining vital pulp. Vitality loss indicates a pulpectomy and an apexification. An apexification is a procedure where medicaments induce the formation of a calcificated barrier (or an artificial barrier formation) in a wide opened apex. Apical calcificated barrier enables root canal filling with gutta-percha points and paste.
The most frequently used materials for direct pulp capping and apexification are calcium hydroxide (Ca(OH)2) and mineral trioxide aggregate (MTA).
Tooth loss has negative effects so it has to be recouped as soon as possible. Implants and bridges are contraindicated because of unfinished skeletal growth so the most common therapy is using a removable partial denture or a cantilever brigde.
Preventive procedures disable factors that endanger tooth vitality. Nutrition and oral hygiene instructions, fluoridation and fissure sealing prevent dental caries, and the usage of mouthguard prevents dental trauma injuries.
