Lysanda Paste: a New Option for Root-end Filling
نویسندگان
چکیده
This study aimed to compare the apical sealing of root-end fillings performed with Lysanda (zinc oxide-eugenol paste) with radiopacifiers (iodoform or zinc oxide) and calcium hydroxide. Root-end cavities were prepared and filled with different materials, as follows: Group I - Lysanda paste with iodoform; Group II - Lysanda paste with iodoform and calcium hydroxide; Group III - Lysanda paste with iodoform and zinc oxide; Group IV - Lysanda paste with zinc oxide; Group V - mineral trioxide aggregate (MTA). After filling, the teeth were immersed in 2% methylene blue for analysis of marginal leakage. It was observed that marginal leakage occurred in all groups. Lysanda paste with iodoform showed the lowest leakage, with no statistically significant difference compared to the other groups. All materials can be considered as good options for root-end filling.

A comparison of pulpectomies using ZOE and KRI paste in primary molars: a retrospective study.
Maintaining a successfully root-treated primary molar has the advantage of preserving the natural tooth--the best possible space maintainer. The purpose of this study was to compare the success of endodontic treatment of nonvital primary molars using ZOE with that of KRI paste. Of 78 necrotic primary molars, 34 were filled with ZOE and 44 with an iodoform-containing paste (KRI). The canals were...

Background and Aim: Today several materials have been used for root- end filling in endodontic surgery. Optimal properties of Pro Root MTA in in-vitro and in-vivo studies has been proven. On the other hand, based on some studies, Root MTA (Iranian Pro Root MTA) and Portland cement are similar to Pro Root MTA in physical and biologic properties. The aim of this study was to evaluate bacterial le...
