OBJECTIVE The objective of this study was to evaluate the cytotoxicity of furcal perforation repair materials, GI and MTA, using cell culture technique. STUDY DESIGN The extract of ProRoot MTA and Ketac Molar were treated on PDL cells in a 96-well tissue-culture plate. Cell proliferation after an incubation period of 3 days was determined by using MTT assay. RESULTS The growth of cultured h...

introduction : furcal perforations are one of the most challenging causes of endodontic failures. several materials including mta have been used for non surgical repair of these perforations. the aim of this study was to compare treatment outcome of furcal perforation treatment in primary molars using root mta and proroot mta. materials and methods: this in vitro study was conducted on 54 prima...

The purpose of treating furcal perforation is to seal the artificial communication between canal space and periradicular tissue prevent periodontal breakdown. duration, size location were identified as primary prognostic factors for determining successful treatment. Mineral trioxide aggregate (MTA) has been regarded an ideal material repair owing its excellent sealability biocompatibility. pres...

objective: the purpose of this study was to investigate the histological response to delib-erate perforation repaired using amalgam or mta either immediately or with delay on cats’ molars. materials and methods: twenty-eight molar teeth from four cats were used in this ex-perimental randomized study. after preparing the access cavity, the floor of pulp cham-bers were deliberately perforated wit...
