introduction: the purpose of this in vitro study was to evaluate the antimicrobial effects of two antibiotics added to ah 26 sealer against enterococcus faecalis (ef). materials and methods: the antimicrobial effects of two antibiotic (amoxicillin and doxycycline) that were added separately to ah 26 sealer was evaluated by using the agar diffusion test and in vitro human root inoculation method...

Background and Aim: Tooth discoloration induced by endodontic materials is a common finding which can impair the aesthetic outcome. The aim of this study was to compare the coronal discoloration induced by Well-Root ST and AH26 root canal sealers by using the Easyshade® colorimeter. Materials and Methods: Forty-five intact maxillary central incisors were involved in this experimental study. Th...

objectives: the aim of this study was to evaluate the effect of gutta percha/ah26 and resilon/realseal se on residual antimicrobial activity of chlorhexidine (chx) in human root dentin and suggest the best filling material when chx is used as final irrigant. materials and methods: one-hundred and forty-four single-rooted human teeth were selected for this study. canals were instrumented to the ...

eradication of microorganisms present in the root canal system is paramount for the successful outcome of root canal therapy. the purpose of this study was to compare the of doxycycline absorbed from mtad into root canal dentin after obturation with gutta-percha/ah26 and resilon/realseal at different time intervals.fifty-one extracted human teeth were instrumented. thirty samples were obturated...

introduction: antibacterial activity is one of the desirable properties of an ideal sealer. this study aimed to compare the antimicrobial effect of three different sealers, i.e. resin (ah26), calcium hydroxide (apexit) and zinc oxide eugenol (zoe) based sealers.   materials and methods: direct contact test with agar diffusion was used in this in vitro study. the freshly mixed sealers were ah26,...

introduction: the purpose of this study was to compare the subcutaneous tissue responses of freshly mixed or set endodontic root canal sealers ( i.e. roekoseal, ah26, ah plus) in wistar albino rats. materials and methods: seventy-two male albino rats weighing 200-250g were used. the animals were randomly divided into six groups of 12 rats each. root canal sealers were implanted in subcutaneous ...

introduction: the purpose of this in vitro study was to assess the apical microleakage of ah26 sealer when three different root canal irrigant regimens were used. materials and methods: eighty single-rooted human teeth were randomly divided into three experimental (n=20) and two control groups (n=10). naocl was used as irrigant during instrumentation, and apical patency was ensured in all teeth...
