Sažetak

Lečenja aficirane pulpe zuba sa nezavršenim rastom korena je još uvek predmet stručnih i naučnih rasprava, između ostalog i zbog neželjenih efekata tradicionalnih preparata na bazi kalcijum hidroksida. Biokeramički materijali se već nekoliko decenija primenjuju u različitim granama medicine, a hidroksiapatit, kao jedna od dve forme kalcijum-fosfatne keramike, ima gotovo istovetan sastav kao neorganski deo kosti, pa je već prihvaćen u endodontskom lečenju zuba sa završ enim rastom korena. Cilj ovog rada je bio da se ispita uticaj hidroksiapatita na apeksogenezu u zuba sa nezavršenim rastom korena i aficiranom pulpom. Ispitivanjem je bilo obuhvaćeno na osam mladih majmuna Cercopithecus Aethiops sa nezavršenim rastom korena zuba. Sintetički hidroksiapatit, veličine čestica od 100 μm je primenjen na trideset dva zuba, podeljenih u dve jednake grupe kod kojih je všena apulpotomija, odnosno visoka pulpotomija. Rendgenološ ka evaluacija rasta korena zuba je vršena pre terapije, kao i tri i dvanaest mesici posle primene HAP, a na osnovu Demjrianove skale za određivanje zrelosti zuba. Na osnovu rendgenološke analize posle 3 meseca je nađeno da je brzina razvoja korena kako pulpotomisanih, tako i visoko pulpotomisanih zuba kod kojih je primenjen HAP bila u 50% slučajeva ista kao kod kontrolnih zuba. Posle 12 meseci stepen razvoja korena zuba je u svih ispitivanih zuba (osim kod jednog od osam zuba sa izvršenom visokom pulpotomijom) bio isti kao u kontrolnih zuba. Dentinski most je bio vidljiv radiološkom analizom u 50% odnosno 87,5% eksperimentalnih zuba posle 3, odnosno posle 12 meseci. Ni u jednom pregledanom zubu rendgenološki nije uočena obliteracija kanala korena, kao ni dentikli ni deformiteti u periapeksnom predelu.
