Possibility of 'Spongio cement' usage for root canal opturation

Abstract

The aim of this study was to evaluate of apical and canal opturation quality of polymethyl metacrylate based material for canal opturation. Investigations were included 60 extracted human single root teeth. Root canals were opturated by standard endodontic technic with three different materials. Teeth were decalcificated and enlightened in 2% methyl salicilate solution. Linear dye penetration was measured with bynocular magnifying glass with 25x magnification. Results showed that the highest apical dye penetration in canals opturated with PMMA based material in relation of AH-26 and Sealapex. Middle value of linear dye penetration in canals opturated with PMMA based material where smear layer was removed was significantly les then in group of teeth where smear layer present.

Cilj ovog rada bio je da se ispita kvalitet apeksnog i kanalnog zaptivanja materijala za opturaciju kanala korena zuba na bazi polimetilmetakrilata (PMMA). U istraživanjima je korišćeno 60 ekstrahovanih jednokorenih zuba. Kanali su punjeni standardnom endodontskom tehnikom,primenom 3 različita materijala. Zubi su potom dekalcifikovani i prosvetljeni u 2% rastvoru metil salicilata. Linearna propustljivost boje merena je binokulamom lupom sa uvećanjem od 25 puta. Rezultati su pokazali najveću apikalnu propustljivost u kanala punjenih materijalom na bazi PMMA (1,06 i 1,31 mm) upoređenju sa AH-26 (0,70mm) i Sealapexom (0,69mm). Linearni prodor boje kod kanala punjenih sa PMMA i sa prethodno uklonjenim razmaznim slojem bio je značajno manji (l,06mm), nego u kanala gde razmazni sloj nije uklonjen (1,3Imm).
