Derek Duggan In vivo microleakage evaluation of two root-filling materials in teeth without a coronal seal (Under the direction of Dr. Martin Trope) Two carrier-based materials were compared to assess their resistance to coronal microleakage in a dog model when no coronal seal was present. Histologic evidence of inflammation and infection were the outcome parameters used. Experimental teeth wer...

AIM To evaluate the push-out bond strength of the dentine-sealer interface with and without main cone for three resin sealers. METHODOLOGY Thirty extracted maxillary premolar teeth with two separate canals were prepared using 0.04 taper Profile instruments to size 35-45. Teeth were divided into three groups for filling using AH Plus, EndoREZ or Resilon sealers. In each tooth, one canal was fi...

introduction: the purpose of this study was to evaluate the efficacy of three methods in removal of resilon/new epiphany self-etch (se) soft resin endodontic obturation system. materials and methods: thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with resilon/epiphany se. the roots were randomly divided into three groups; group 1 roots were retre...

introduction: the aim of the present experimental study was to evaluate the push-out bond strength of dorifill, epiphany and mta-fillapex sealers to root canal dentin in presence and absence of smear layer (sl). methods and materials: sixty human single-rooted teeth were selected and divided into six groups ( n= 10). the canal irrigation protocol in groups 1, 3 and 5 consisted of 2.5% naocl dur...

introduction: the aim of the present study was to investigate and compare the apical sealing ability of resilon/epiphany-filled root canals with those that were obturated with gutta-percha/ah-plus endodontic sealer. materials and methods: a total of 60 extracted human single-rooted teeth were selected; 25 teeth for each test group and five for each control group. after conducting conventional e...

INTRODUCTION The importance of perfect apical seal in endodontics, more specifically in periradicular surgery, is the motivation/reason for development of root-end filling materials with favorable physical, chemical and biological characteristics. The aim of this in vitro study was to evaluate the marginal adaptation of root-end filling materials using scanning electron microscopy. MATERIALS ...

The aim of this study was to evaluate the effects of different irrigants on sealer-dentin bond strength when using Real Seal. Thirty single-rooted teeth were divided into 3 groups. In one group, the teeth were irrigated with 3 mL of 2.5% NaOCl after each file change, flushed with 17% EDTA for 3 min and finally rinsed with 3 mL of 2.5% NaOCl. In the other two groups, rinse with NaOCl was replace...
