Terapijski efekat plazme obogaćene trombocitima i autotransplantata vezivnog tkiva sa periostom u zbrinjavanju gingivalnih recesija
Sažetak
Uvod/Cilj. Sve veća zastupljenost gingivalnih recesija u svakodnevnoj kliničkoj praksi uslovila je zahteve za što efikasnijim rekonstruktivnim hirurškim procedurama, u cilju rešavanja estetskih nedostataka i subjektivnih tegoba usled povlačenja gingive. Cilj rada bio je da se uporedi efikasnost lečenja autotransplantatom vezivnog tkiva (ATVT) sa periostom i plazme obogaćene trombocitima (PRP) sa ATVT sa periostom, ali bez PRP, na širinu keratinizirane gingive. Metode. Studijama je bilo obuhvaćeno 20 zuba sa recesijama gingive klase I i II prema Mülleru. U toku terapije 10 recesija lečeno je ATVT sa periostom u kombinaciji sa koronarno pomerenim režnjima (ATVT grupa). Na kontralateralnoj strani, isti broj recesija lečen je ATVT uz koronarno pomeren režanj i uz primenu PRP (PRP + ATVT grupa). Od kliničkih parametara praćena je širina keratinizovane gingive kao pokazatelj pokrenutih regenerativnih procesa. U statističkoj obradi rezultata korišćen je Studentov t-test. Rezultati. Analizom kliničkih parametara ustanovljeno je statistički značajno proširenje zone keratinizirane gingive, što je od izuzetnog značaja za regeneraciju s tim što je proširenje bilo izraženije u ATVT + PRP grupi. Procentualno gledano, prekrivenost korena u ATVT grupi iznosila je 90%, a u ATVT + PRP grupi 93,5%. Zaključak. Primenom koncepta aktivne regeneracije odnosno primenom PRP i stimulativnim dejstvom aktiviranih faktora rasta iz trombocita, postiže se regeneracija dubljeg periodontalnog tkiva što je bitan preduslov za uspešno zbrinjavanje recesije gingive.
