A. Pallares et V. Faus, A COMPARATIVE-STUDY OF THE SEALING ABILITY OF 2 ROOT-CANAL OBTURATIONTECHNIQUES, Journal of endodontics, 21(9), 1995, pp. 449-450
A comparison was made of the ability of two root canal obturating tech
niques to prevent dye microleakage: gutta-percha lateral condensation
and mechanically plasticized gutta-percha (JS Quickfill). Twenty centr
al incisors were prepared and obturated by each technique, After rende
ring the teeth transparent, linear dye penetration was found to be 0.4
8 and 0.52 mm, respectively. The difference between the two techniques
was not significant. As for the distribution of the sealing cement (A
H26) in the teeth obturated with JS Quickfill, the cement was located
in the most peripheral zone of the obturation alongside the dentinal w
alls, whereas the gutta-percha was found in the central part of the ca
nal obturating material.
