Silver diamine fluoride and cleaning methods effects on dentin bond strength.

Purpose: To assess the effect of silver diamine fluoride (SDF) application on bond strength of current adhesive systems to caries-affected dentin and cleaning procedures to overcome SDF's influence on adhesion to dentin.

Methods: 64 human third molars were randomly divided in eight groups for microshear bond strength testing (MBS). Samples of sound and artificial caries-affected human dentin were treated or not with 38% SDF and restored with an etch-and-rinse or a self-etch bonding system.

The effect of silver diamine fluoride and cleaning methods on bond strength of glass-ionomer cements to caries-affected dentin.

Purpose: To evaluate the effect of silver diamine fluoride (SDF) application on the microshear bond strength (MBS) of glass-ionomer cements (GIC) to caries-affected dentin (Part 1) and dentin cleaning methods to reduce SDF's potential effect on MBS (Part 2).

Methods: For Part 1, 56 extracted human teeth were randomly divided into eight groups with GIC, 38% SDF application and dentin substrate. Samples of artificial caries-affected human dentin were treated or not with 38% SDF and restored with conventional or resin-modified GIC.

Abfraction lesions: etiology, diagnosis, and treatment options.

Abfraction is a type of noncarious cervical lesion (NCCL) characterized by loss of tooth tissues with different clinical appearances. Evidence supports that abfraction lesions, as any NCCLs, have a multifactorial etiology. Particularly, the cervical wear of abfraction can occur as a result of normal and abnormal tooth function and may also be accompanied by pathological wear, such as abrasion and erosion.
