STATEMENT OF THE PROBLEM Endodontic irrigants and medicaments may affect the bond strength of intracanal posts to root dentin. PURPOSE The aim of this study was to compare the effect of calcium hydroxide (Ca(OH)2) and 2% chlorhexidine gel (CHX) on bond strength of fiber post cemented with resin cement to root dentin. MATERIALS AND METHOD This in vitro experimental study was conducted on 36 ...

The purpose of this in vitro study was to investigate the effects of the use of calcium hydroxide as an intracanal dressing on the sealing ability of a thermoplastic synthetic polymer-based root filling (Resilon). Forty-seven single rooted teeth were decoronated and instrumented to ISO sizes 40. The teeth were randomly divided into three experimental groups of 15 roots each. Group 1 was immedia...

INTRODUCTION The aims of this study were i) to define the chemical constituents of Cuminum cyminum (cumin) essential oil, ii) to compare the antimicrobial activity of this oil to that of chlorhexidine (CHX) and co-trimoxazole on planktonic and biofilm forms of bacteria isolated from the teeth with persistent endodontic infection and iii ) to compare the cytotoxicity of these medicaments on L929...

introduction: one of the major contributing factors, which may cause failure of endodontic treatment, is the presence of residual microorganisms in the root canal system. for years, most dentists have been using calcium hydroxide (ch) as the intracanal medicament between treatment sessions to eliminate remnant microorganisms. reducing the size of ch particles into nanoparticles enhances the pen...

introduction: an ideal intracanal medicament should be able to eliminate any remaining intracanal microorganism. the aim of this study was to compare the antimicrobial effects of bioglass 45s5 with calcium hydroxide on enterococcus ( e ) faecalis in-vitro . materials & methods: direct exposure test (det) was used to evaluate the antimicrobial effect of bioglass 45s5, calcium hydroxide and norma...
