Comparison between calcium hydroxide mixtures and mineral trioxide aggregate in primary teeth pulpotomy: a randomized controlled trial

J. appl. oral sci; 27 (), 2019
Abstract Objectives: To evaluate the effect of calcium hydroxide (CH) associated with two different vehicles as a capping material for pulp tissue in primary molars, compared with mineral trioxide aggregate (MTA). Methodology: Forty-five primary mandibular molars with dental caries were treated by conv...

Inhibitory effect of reduced graphene oxide-silver nanocomposite on progression of artificial enamel caries

J. appl. oral sci; 27 (), 2019
Abstract The use of antimicrobial agents is an efficient method to prevent dental caries. Also, nanometric antibacterial agents with wide antibacterial spectrum and strong antibacterial effects can be applied for prevention of dental caries. Objectives: The aim of this study was to evaluate the inhibito...

Influence of mandibular and palatal intraoral appliances on erosion in situ study outcome

J. appl. oral sci; 27 (), 2019
Abstract The standardization of in situ protocols for dental erosion is important to enable comparison between studies. Objective: Thus, the objectives of this study were to evaluate the influence of the location of in situ intraoral appliance (mandibular X palatal) on the extent of enamel loss induced ...

Surface and vertical dimensional changes of mineral trioxide aggregate and biodentine in different environmental conditions

J. appl. oral sci; 27 (), 2019
Abstract Surface changes in biological environments are critical for the evaluation of physical and biological activity of biomaterials. Objective: This study investigated surface alterations of calcium silicate-based cements after exposure to different environments. Material and Methods: Forty-eight cyl...

Shrinkage stress and elastic modulus assessment of bulk-fill composites

J. appl. oral sci; 27 (), 2019
Abstract Bulk-fill composites were introduced in dentistry to accelerate clinical procedures while providing adequate outcomes. Concerns regarding the use of bigger composite increments rely on the polymerization shrinkage and shrinkage stress, which may generate gaps on the adhesive interface and result...
