Evaluating the effect of poly (amidoamine) treated bioactive glass nanoparticle incorporated in universal adhesive on bonding to artificially induced caries affected dentin.

Background: The purpose of this study was to evaluate remineralisation and its effect on microtensile bond-strength of artificially induced caries affected dentin (CAD) when treated with a commercial universal adhesive modified with poly(amidoamine) dendrimer (PAMAM) loaded mesoporous bioactive glass nanoparticles (A-PMBG).

Material And Methods: Mesoporous bioactive glass nanoparticles (MBG) were synthesised using sol-gel process, where PAMAM was loaded (P-MBG) and added to commercial adhesive at different weight percentages (0.2, 0.

Development of Novel Antimicrobial Dental Composite Resin with Nano Cerium Oxide Fillers.

Objectives: To assess the antibacterial efficacy of experimental dental composite resin with cerium oxide nanoparticles as fillers.

Methods: The cerium oxide nanoparticles were prepared by the coprecipitation procedure. Synthesized 3wt% CeO nanoparticles were added to the composite resin as antibacterial filler.

Evaluation of accuracy of fit in cast metal post fabricated with direct and indirect techniques using micro-CT - An study.

Context: Accuracy of fit of cast metal posts fabricated with direct and indirect techniques.

Aims: To evaluate the accuracy of fit of cast metal posts fabricated with direct and indirect techniques using micro-CT.

Materials And Methods: Sixty extracted human maxillary central incisors were used.

Comparative evaluation of retreatability of calcium silicate-based root canal sealers and epoxy resin-based root canal sealers in curved canals-An micro-CT analysis.

Objective: To compare and evaluate the retreatability of calcium silicate-based root canal sealers and epoxy resin-based root canal sealers in curved canals using micro-CT scanning.

Materials And Methods: Forty-five maxillary molars with curved roots were selected after confirming with the Schneiders test. Teeth were decoronated near the cemento-enamel junction and moderate to severely curved canals were selected for the study using cone-beam computed tomography.

Effects of chitosan oligosaccharide and calcium hypochlorite on dentinal biofilm and smear layer removal - SEM analysis.

Background: The complex structure and irregularities of root canal walls are liable for infection by several bacterial species. Thus, the use of irrigants and auxiliary chemical solutions associated with instrumentation is necessary for effective eradication of the biofilm as well as complete removal of the smear layer.

Aim: To evaluate the effects of calcium hypochlorite and chitosan oligosaccharide (COS) in disinfecting Enterococcus faecalis root canal biofilm and smear layer removal with minimal erosion.

The effect of leachable components of resin cements and its resultant bond strength with lithium disilicate ceramics.

Objectives: To evaluate the leachable components of resin cements in oral simulating fluids using high performance liquid chromatography and its resultant shear bond strength with ceramics.

Methods: Forty extracted permanent human mandibular molar teeth were sectioned horizontally with a disc beneath the dentino-enamel junction to expose the coronal dentin surface and later finished with 600-grit silicon carbide paper to create a uniform flat surface. Forty Lithium Di-silicate Ceramic block cylinders were sliced in a saw cutting machine at 250 rpm under water-cooling to obtain the discs.

Effect of vital bleaching with solutions containing different concentrations of hydrogen peroxide and pineapple extract as an additive on human enamel using reflectance spectrophotometer: An study.

Aim: This study aims to evaluate the color change in human enamel bleached with three different concentrations of hydrogen peroxide, containing pineapple extract as an additive in two different timings, using reflectance spectrophotometer.

Background: The study aimed to investigate the bleaching efficacy on natural teeth using natural enzymes.

Materials And Methods: Baseline color values of 10 randomly selected artificially stained incisors were obtained.

Comparative evaluation of shear bond strength of zirconia restorations cleansed various cleansing protocols bonded with two different resin cements: An study.

Context: Yttria partially stabilized tetragonal zirconia polycrystalline restorations have gained widespread use because of its enhanced strength and esthetics. During the try-in process, zirconia is likely to be contaminated with saliva. This contamination leads to a clear weakening of the bond between restorative material and cement.
