Performance of self-etching adhesives on caries-affected primary dentin treated with glutaraldehyde or silver diamine fluoride.

Objectives: to evaluate the quality and stability of adhesive interfaces established by self-etching adhesives on caries-affected primary dentin (CAD) treated with glutaraldehyde (GA) or silver diamine fluoride (SDF).

Methods: 42 primary molars were exposed to a microbiological caries-inducing protocol and divided into 6 groups according to the adhesive system (Clearfil SE - CL or FL Bond II - FL) and pretreatment (water, GA or SDF) applied on CAD. One tooth from each group was analyzed for surface modification using infrared spectroscopy.

Proteolytic activity, degradation, and dissolution of primary and permanent teeth.

Background: Primary and permanent teeth composition may influence dissolution and degradation rates.

Aim: To compare the dissolution and degradation of primary and permanent teeth.

Design: Enamel and dentin powders were obtained from primary molars and premolars and incubated within different pH buffers.
