Influence of obturation technique on penetration depth and adaptation of a bioceramic root canal sealer.

Aim: Evaluation of the impact of three different obturation techniques on the penetration depth and adaptation of a bioceramic root canal sealer(BioRoot RCS) to root dentin using scanning electron microscope and confocal laser scanning microscope.

Materials And Methods: Recently extracted ninety mandibular premolar teeth of similar dimensions (±0.2 mm) with single canals and straight roots were segregated into three experimental groups ( = 30 each) based on the method of obturation used, i.

Synergistic Effect of Arginine on Remineralization Potential of Fluoride Varnish and Nanohydroxyapatite on Artificial Caries Lesions: An Study.

Aim And Objective: To evaluate the synergistic effect of arginine on the remineralizing potential of fluoride varnish and nanohydroxyapatite.

Materials And Methods: A total of 100 teeth were taken; of them, 50 teeth were allotted for microhardness test and 50 teeth for scanning-electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDX) analysis. Fifty teeth used for hardness testing were sectioned to obtain 100 samples, and the baseline hardness values were measured.

Efficacy of hydroxyapatite and silica nanoparticles on erosive lesions remineralization.

Aim: The aim is to assess and compare the mineral gain and penetration depth of hydroxyapatite and silica nanoparticle infiltrates into artificially created erosive lesions of enamel and dentin.

Materials And Methods: Sixty extracted human molars were sectioned to obtain enamel and dentin samples ( = 60 each). They were demineralized using citric and formic acid, respectively, to create erosive lesions on enamel and dentin surfaces.

Microtensile Bond Strength Evaluation of Composite Resin to Discolored Dentin After Amalgam Removal.

Background To obtain prolonged clinical success with composite restorations, better bonding of resin to the tooth substrate is crucial. Aim The study was aimed to evaluate the microtensile bond strength (µTBS) of bulk-fill composite resin restorations when bonded to a cavity previously restored with amalgam, comparing with that of freshly prepared dentin. Materials and method Mesio-occlusal cavity preparations were done on 80 extracted human mandibular molars with a buccolingual width of 4 mm and a 1.
