background & aim: antibacterial effect of the sealers which are used in root canal therapy is a factor which increases the rate of success in root canal therapy. the aim of this study was to compare the antibacterial effect of three sealers (zoe, ah26, dorifill) on two bacterial species, staphylococcus aureuse and streptococcus mutans immediately after mixing and one week after mixing. methods ...
The primary tooth pulpectomy is a common clinical procedure. The choice of filling material is important to the success rate, but antibacterial properties of such materials against organisms known to inhabit infected primary root canals have not been well documented. This study compared the antibacterial effectiveness of 10 materials: 1. Calcium hydroxide mixed with camphorated parachlorophenol...
introduction: the aim of this animal study was to evaluate the histological response of the new nano zinc-oxide eugenol (nzoe) sealer in comparison with pulp canal sealer (zoe based) and ah-26 (epoxy resin sealer). methods and materials: a total of 27 wistar rats were used. four polyethylene tubes were implanted in the back of each rat (three tubes containing the test materials and an empty tub...
The aim of this systematic review was to determine whether there is a root canal filling for deciduous teeth equally or more effective than zinc oxide-eugenol cement (ZOE). Six clinical trials selected for inclusion were independently reviewed by two researchers. Only two showed statistically significant different success rates between the test and the control groups. One found that an iodoform...
background and aims. with availability of hydrophilic sealers, drying of the canals before endodontic obturation is still a matter of debate. the aim of this study was to compare the apical micro-leakage of ah26, excite dsc, mta fillapex, and zoe sealers in dry and moist root canals. materials and methods. this experimental study was performed on 90 extracted maxillary central incisors. rotary ...
It has been accepted traditionally that the setting of zinc oxide-eugenol (ZOE) cements is the result of the formation of zinc eugenolate crystals.1 A recent study pointed out that at least seven hours elapsed before zinc eugenolate crystals precipitated from a clear solution of zinc acetate in eugenol.2 Accelerated ZOE, however, set in as short a time as three minutes.3 Electron microscopy, el...
This study compared the antimicrobial effectiveness of nine dental materials and a negative control agent against 21 strains or species of bacteria using an agar diffusion assay. The materials were: 1. Camphorated parachlorophenol mixed with calcium hydroxide (CPC + Ca(OH)2). 2. CPC mixed with zinc oxide (CPC + ZnO). 3. Formocresol mixed with zinc oxide and eugenol (FC + ZOE). 4. Chlorhexidine ...
The antimicrobial and cytotoxic effects of Kri 1 paste, an iodoform-based primary tooth filling material, were compared with zinc oxide-eugenol (ZOE), using in vitro techniques. Antimicrobial evaluation involved measuring inhibition zones of Streptococcus faecalis on brain heart agar. Cytotoxicity evaluation involved direct cell-medicament contact experiments of 4-hr and 24-hr duration using fr...
BACKGROUND A trial involving adults 50 years of age or older (ZOE-50) showed that the herpes zoster subunit vaccine (HZ/su) containing recombinant varicella-zoster virus glycoprotein E and the AS01B adjuvant system was associated with a risk of herpes zoster that was 97.2% lower than that associated with placebo. A second trial was performed concurrently at the same sites and examined the safet...
