PURPOSE The aim of this study was to compare the effects of different denture cleansers on the surface roughness and microhardness of various types of posterior denture teeth. MATERIALS AND METHODS 168 artificial tooth specimens were divided into the following four subgroups (n=42): SR Orthotyp PE (polymethylmethacrylate); SR Orthosit PE (Isosit); SR Postaris DCL (double cross-linked); and SR...

Background. The aim of this study was to evaluate the effectiveness of different concentrations of sodium hypochlorite (NaOCl) solution in reducing bacterial growth in Enterococcus faecalis biofilms in root canals. Methods. The root canals of maxillary central incisors of 104 subjects underwent chemomechanical debridement. In order to remove the smear layer, 5.25% sodium hypochlorite solution w...

AIM To evaluate the pitting and crevice corrosion characteristics of stainless steel (SS) and NiTi endodontic files in R-EDTA and NaOCl irrigating solutions. METHODOLOGY The corrosion behaviour of two H-files produced from different SS alloys (Mani, AISI 303 SS, Dentsply Maillefer, AISI 304 SS) and one file produced from NiTi alloy (Maillefer) was determined in R-EDTA and NaOCl irrigating sol...

Chlorination is widely used method in the disinfection of drinking and utility water worldwide. In this study, cytotoxic and genotoxic effects of sodium hypochlorite were investigated by the cytokinesis-block micronucleus assay and chromosomal aberration analysis on human peripheral lymphocytes in vitro. A significant increase in chromosomal aberration frequency was observed in all treatments o...

Objective: This study aimed to compare the effect of sodium hypochlorite (NaOCl), chlorhexidine (CHX), ethylene daimine tetra acetic acid (EDTA) and etidronic (HEBP) solutions their combinations on a push-out bond strength fiber posts root canal dentin microhardness. Material Methods: Sixty human maxillary central incisors were sectioned below cementoenamel junction, roots endodontically treate...

ABSTRACT Debonding between post and resin cement often occurs due to inadequate smear layer removal.Currently, the wide use of Chitosan as an alternative irrigating solution can remove layer. This studyaimed determine effect 0.2% chitosan high molecule nanoparticle (CHMN) on push-out bond strength ofresin in post-restoration types adhesion failure using different solutions. Endodontictreatment ...

Amaç: Bu çalışmanın amacı kök kanal tedavisinde kullanılan farklı irrigasyon solüsyonlarının yüzey gerilimi değerlerini karşılaştırmaktır. Gereç ve Yöntem: %5.25 NaOCl, %9 HEBP, %2 PAA, %17 EDTA, NaOCl + EDTA değerleri damla şekli analiz cihazı DSA30 (Kruss, Hamburg, Almanya) ile ölçüldü. Her solüsyonu için 10 ayrı ölçüm yapıldı. Veriler mj/m2 cinsinden kaydedildi. Grupların ortalama standart s...

UNLABELLED An increase in dentin roughness, associated with surface composition, contributes to bacterial adherence in recontaminations. Surface roughness is also important for micromechanical interlocking of dental materials to dentin, and understanding the characteristics of the surface is essential to obtain the adhesion of root canal sealers that have different physico-chemical characterist...
