The Effect of Bleaching Agents on the Color Stability of Ceromer and Porcelain Restorative Materials In Vitro
Clinicians should be aware that bleaching might induce color changes of some restorative materials.
The Effect of Polishing Technique on 3-D Surface Roughness and Gloss of Dental Restorative Resin Composites
This article discusses the surface finish of different modern types of composites polished using different polishing protocols used in all dental practices.
The adhesively bonded ceramic restorations presented satisfactory results after five years of clinical service. There was no significant difference between ceramic systems regarding survival.
Microfilled composite, nanohybrid composite, and compomer give similar results in treatment of noncarious cervical lesions within a two-year evaluation period.
Light acceleration of the bleaching process, using a laser or halogen light, does not seem to be more beneficial than chemical activation with regard to the stability of tooth color over a period of three months.
Highly repeated preheating cycles seem to negatively influence the flexural strength of resin composites. Assuming dental clinicians are aware they are using the same composite syringe for more than 20 cavities and a preheating procedure is steadily adopted, then the use of single-use composite compules instead of syringes should be adopted.
The use of diamond burs with different roughness did not increase the bond strength of self-etch systems and etching pattern in sclerotic dentin. Clinicians should avoid using this procedure when applying self-etch adhesive.
Bond Durability of Adhesives Containing Modified-monomer With/Without-fluoride After Aging in Artificial Saliva and Under Intrapulpal Pressure Simulation
Adhesives with hydrolytically stable modified monomers could be a promising approach to enhance bonding durability.
Several tooth whitening products are available to consumers on the market. This study questions whether the use of whitening mouth rinses and toothpaste can result in bleaching efficacy similar to that of the 10% carbamide peroxide at-home bleaching technique.
Effect of Different Adhesion Strategies on Bond Strength of Resin Composite to Composite-dentin Complex
When composite materials are to be repaired next to dentin, preferably the substrate composite and repair composite should be of the same type. Conditioning the substrate composite with silica coating and silanization after etching the dentin add to the repair strength of the composite-dentin complex when compared to the success of silane application only.
Pulpal and Periapical Response After Restoration of Deep Cavities in Dogs' Teeth With Filtek Silorane and Filtek Supreme XT Systems
Both the silorane and methacrylate resin systems showed good tissue compatibility, suggesting that their placement in contact with deep dentin in clinical procedures may be appropriate.
The present study was undertaken to examine the effect of phosphoric acid (PA) etching on the bond strength and acid-base resistant zone (ABRZ) formation of a two-step self-etching adhesive to enamel. Taking both bond strength and ABRZ formation into consideration, we recommend bonding enamel by the means of directly applying Clearfil SE Bond adhesive after 35% PA etching.
Effect of Surface Treatments on Microtensile Bond Strength of Repaired Aged Silorane Resin Composite
To obtain high repair bond strength on aged silorane composite, aluminum oxide sandblasting should be used as a surface treatment procedure. After aluminum oxide sandblasting, either silorane composite with the LS system adhesive or methacrylate composite with a methacrylate dental adhesive can be used.
Effects of Two In-Office Bleaching Agents with Different pH on the Structure of Human Enamel: An In Situ and In Vitro Study
Salivary pellicle and adequate calcium and phosphate ions present in natural human saliva play pivotal roles in protecting the surface of human enamel during the process of in-office bleaching.
