The present study aimed to investigate the inhibitory effect of Lactobacillus rhamnosus (B-445) as a probiotics irrigant on growth Enterococcus faecalis.Forty-two extracted single human canal anterior teeth were prepared with rotary instrumentation and sterilised. Teeth divided into 3 groups according type irrigant, N = 14. Three experimental inoculated E. faecalis cultured for 21 days before use; Group 1 was 2.5% NaOCl (positive control), 2 saline (negative probiotic irrigant. Paper point...

Abstract Objective This study was done to evaluate the effect of prepared Moringa oleifera -based root canal irrigant compared conventionally used irrigants on microhardness dentin and smear layer removal. Materials methods One hundred freshly extracted teeth with single were divided into 5 groups according used: group 1, saline; 2, ; 3, + chlorhexidine; 4, 5, sodium hypochlorite. Root preparation using Protaper universal system till size F5 one after each file. Fifty measure microhardness,...

The adhesion between the resin composite and perforation repair materials critically influences treatment outcomes. This study aimed to investigate effect of different surface on bond strength composite. Ninety blocks were prepared from Mineral trioxide aggregate (MTA) Angelus, EndoSequence (ERRM) one experimental Nano-MTA (n = 30 each). Then, they divided into two subgroups according performed, which was either etching with phosphoric acid gel or air abrasion Al2O3 particles. Adhesive...

Aim: This study aimed to compare the push-out bond strength of two different endodontic sealers with obturation techniques root dentin.Methods: Thirty single rooted extracted teeth were selected and instrumented using ProTaper rotary files.The canals assigned into three equal groups based upon sealer technique used.Group I: Epoxy resin-based (AH Plus Sealer) cone gutta percha, Group II: continuous wave compaction (CWC) III: Bioceramic (CeraSeal) bioceramic coated Bio GP Points.Roots...

Abstract Background Apicoectomy with retrograde filling is considered as a tooth saver. Mineral trioxide aggregate (MTA) mostly recommended root-end material it proved to have excellent sealing ability and hard tissue repair. Aside from these advantages, MTA has some disadvantages, such weak handling properties, long setting time, discoloration potential. Nanotechnology now undergoing rapid development. Recently, experimental nano-white mineral (nano-WMTA) was prepared introduced by NanoTech...

Abstract Background This research assessed two materials to be used as endodontic sealing material. The setting time, pH change, calcium ions release, microhardness and push-out bond strength were compared. Methods In this in vitro experimental study, comparison was done between: one commercial perforation repair material MTA Angelus Nano-MTA. For each material, testing for time using Vicat apparatus, measurement of values established by meter, the discharged measured at 1 day, week 4 weeks...

Aim: The purpose of this research was to compare the cytotoxicity effect two naturally based intracanal medications, which are silver nanoparticles (AgNPs) and AgNPs with curcumin, commonly utilized calcium hydroxide (Ca(OH)2). Materials Methods: Evaluation done using cell line in vitro. used our study Gingival Fibroblast cells (ATCC PCS-201-012). After 48 h exposure, water soluble tetrazolium salt (WST-1) assay assess vitality by Abcam kit. Fifty-four samples were categorized randomly into...

Abstract Background This study aimed to evaluate the remaining amount of intra canal medicament in root canals and their effect on microhardness radicular dentine. In this study, ninety straight single-rooted teeth were used. Teeth decoronated at cemento-enamel junction ensure a uniform length 14 mm (± 1 mm). Root prepared using ProTaper rotary files till size F5. The then randomly assigned 3 treatment groups ( n = 30); Group 1: Ca(OH) 2 pastes (Metapex), 2: Moringa oleifera leaf powder...

The aim of this in vitro study was to assess the effect obturation technique and cementation timings on bonding fibre-reinforced posts root canal walls.Twenty extracted teeth were randomly allocated two groups according timing. Central incisors with single canals used after being decoronated. Every tooth {vertical compaction group} (VC) group (n = 10) had been obturated using {E & Q plus system} cemented same day; other (CO) conventional lateral one week. "SF" Fiber Rely X ARC resin cement...

Aim: In an attempt to move toward exploration of the antibacterial properties herbal products, this study evaluated effect how addition Moringa would affect physical commercial Endofil sealer. Materials and Methods: An experimental in vitro was performed using three sealers. There were four groups study: Group A (ZnO/E sealer alone), B root), C leaf), D leaf extract liquid). Measurements carried out according International Organization for Standardization (ISO) standardization 6876:2012....

Aim: To clinically evaluate the effect of continuous ultrasonic and diode laser 810 wave length irrigation activation techniques on postoperative pain bacterial reduction in single visit endodontic treatment mandibular molars.
 Material methods: Forty patients requiring root canal therapy for necrotic molars teeth were included this study with age ranges between 20 45 years. In all cases, was carried out using Revo-S rotary file system crown down sequence. NaOCl 2.5% solution used...

Background/aim Complete removal of intracanal medication from the canals before root canal obturation is an essential step. This research was conducted to comparatively assess remaining debris after three medications: silver nanoparticles (AgNPs) paste, with curcumin and calcium hydroxide (Ca(OH) 2 ) paste on walls their effect microhardness radicular dentin. Materials methods Thirty human extracted single-rooted teeth were selected National Research Centre Dental Clinic, Egypt. The crowns...
