Gluma desensitizer on dentin bonding agents and the role of adhesion between
Protein coagulation,[link widoczny dla zalogowanych], resulting in irregular status of the original dentin surface change, which affects the ZPC and the tooth surface,[link widoczny dla zalogowanych], the formation of inter-Mechanical Interlocking, which led to the decline of its adhesion. ② the impact of GIC: Glu-ma reduced asked GIC and dentin adhesion, but no significant difference (P> Q.01). The reason may be between GIC and the dentin bond strength was obtained not only by the irregular status of sticky surface to obtain the mechanical retention, and the tooth structure and the chemical reaction does occur, forming a chemical bond strength, which is guaranteed for solid dentin bonding conditions, Gluma desensitizer on the formation of chemical bonds less impact force, so ask the GIC and dentin had no effect on adhesion. ③ impact on the PCC: Gluma reduces the PCC and asked dentin adhesion,[link widoczny dla zalogowanych], but no significant difference. (P> 0.01) PCC and the GIC has a similar bonding mechanism, and its conclusions are consistent. ④ impact on the RC: Gluma increased Permacen @ and dentin adhesion to ask, but no significant difference (P> 0.01). RC is resin-based adhesive, the adhesive penetrate into the relay received by the irregular surface and the dentin tubules to form resin tag co-produced with mechanical lock, and the dentin surface chemical reaction. Gluma Gluma desensitizer actual bonding system for the dentin bonding agent, is a coupling agent with aldehydes, the so-called coupling agents are those produced under certain conditions active groups on both sides with the bonding interface is surface and substrate bonding formation of chemical bonds, and enhance the bonding strength of a class of compounds, it provides a combination of chemical bonding repair, Gluma coupling agent contained in the aldehyde and dentin collagen in the amino or imino reaction produces a compound containing hydroxyl groups, so that the dentin surface crosslinked to form a favorable hydrogen bonds with HEMA or other intermolecular forces of the active surface layer, and through the use of HEMA and the subsequent formation of adhesive resin copolymer . Therefore, Gluma desensitizer not only did not reduce t] ~ Permacem @ and dentin adhesion to ask, there is an increasing anti-trend, but no significant difference. In summary, Gluma desensitizer of different dentin bonding agents and sticky relay in different effects, depending on the desensitization of the compatibility agent and bonding agent,[link widoczny dla zalogowanych], dentin tooth structure for later rubbed dentin desensitizer sensitive for the mitigation, protect the pulp had a significant effect, but not a substitute for the application of desensitizer correct clinical practice, should be strictly regulate the operation to ensure the health of every vital teeth.
