On the basis of available evidence , MTA presented good marginal adaptation to dentine walls .
This systematic review analysed the literature comparing marginal adaptation of mineral trioxide aggregate ( MTA ) with other filling material s in root-end cavities .
Sealing ability and adaptation of root-end filling materials in cavities prepared with different techniques.
The aim of this study was to evaluate the sealing ability and marginal adaptation of calcium silicate-based cements ( CSCs ) in root-end cavities prepared by ultrasonic and laser tips . A total of 72 extracted human maxillary incisor teeth were r and omly divided as 60 teeth in experimental groups and 6 teeth each for positive and negative control groups . Specimens in experimental groups were obturated , their root-end resections were performed and r and omly divided into six groups ( n = 10 ) as follows : G1 : Ultrasonic retrotip + MTA , G2 : Ultrasonic retrotip + Calcium Enriched Mixture ( CEM ) , G3 : Ultrasonic retrotip + Biodentine , G4 : Er : YAG laser tip + MTA , G5 : Er : YAG laser tip + CEM , G6 : Er : YAG laser tip + Biodentine . The sealing ability was measured by fluid transport method . Six specimens from each experimental group were r and omly selected to analyze marginal adaptation and prepared for scanning electron microscopy ( SEM ) analysis . Micrographs were scored and also analyzed using Image J software . Data were analyzed with ; two-way ANOVA , Bonferroni , Kruskall-Wallis , Mann-Whitney-U , Siegel & Castellan , and Spearman correlation coefficient tests . No significant difference was found between material s regarding the sealing ability and marginal adaptation ( p > 0.05 ) . Significantly greater fluid movement and poor marginal adaptation were seen for material s placed in cavities prepared by laser tips ( p < 0.05 ) . Positive correlation was found between the results of scoring and Image J analysis of SEM images ( r = 0.596 , p < 0.001 ) . Fluid transport method and SEM analysis gave similar results suggesting the use of ultrasonic-retrotips for preparing root-end cavities which are going to be filled with one of these CSCs
