A Comparative Study of Five Different Obturation Techniques

Svrha istraživanja bila je procijeniti prikladnost i kvalitetu ispuna korijenskog kanala postignutih lateralnom kondenzacijom, vertikalnom kondenzacijom te tehnikama Thermafil, Ultrafil i Obtura II. Sedamdeset i pet ravnih i zavinutih korijenskih kanala ekstrahiranih ljudskih zuba instrumentirano je tehnikama “crown-down” / “step-back”, uz uporabu 3%-tnog natrij-hipoklorita. Apikalna prohodnost provjerena je K-pilicom veličine 15, a napravljeno je pet skupina po 15 korijenskih kanala te su tretirani različitim tehnikama punjenja. Roekoseal Auotmix rabljen je kao sredstvo punjenja u svim slučajevima. Zubi su rendgenski snimljeni radi procjene opće adaptacije materijala i prepunjenosti. Nije bilo znatnih razlika u sveukupnom punjenju korijenskih kanala, ni u rendgenskoj gustoći ni u adaptaciji uz zidove kanala. Sve termoplastične tehnike punjenja korijenskih kanala pokazale su prihvatljivo punjenje te su dobro brtvile bez statistički znatnih razlika u odnosu prema lateralnoj kondenzaciji. Ispuni korijenskih kanala bili su rendgenski gusti i dobro adaptirani u cijeloj duljini korijenskog kanala.The aim of the study was to evaluate the adaptation and quality of root fillings achieved by the lateral condensation, vertical condensation, Thermafil, Ultrafil and Obtura II techniques. Seventy-five straight and curved root canals of extracted human teeth were prepared according to the crown-down / step-back technique using 3% sodium hypochlorite. Apical patency was verified with a size 15 K-file and five groups of 15 root canals were formed for the different obturation techniques. Roekoseal Automix was used as sealer in all cases. Teeth were radiographed for overall material adaptation and filling material extrusion. There were no significant differences in the overall canal obturation and radiographic density and adaptation to canal walls. All thermoplastic obturation techniques demonstrated acceptable root canal filling and sealed well with no statistically significant difference between them and in comparison to lateral condensation. Root canal fillings were radiographically dense and well adapted throughout the entire root canal system
