The dentin chemical degradation and saliva roles on Noncarious Cervical Lesions – literature review

This review elucidates the dental structure chemical degradation and saliva roles in the origin and progression of NCCLs. Dentin chemical degradation is a predominant factor that contributes to the origin and progression of noncarious cervical lesions, which includes the biocorrosive factors: chemical, biochemical, electrochemical and piezoelectric dentin effects. The biocorrosive process involves endogenous and exogenous agents. As regard to saliva roles, the flow rate, buffering capacity, pH and its protein composition are valid parameters to identify biocorrosive factors. Thus, the association of acids agents, altered salivary parameters and specifics proteases are important conditions to promote dental wear. It can be concluded that endogenous and exogenous acids agents, salivary parameters and specific oral biomarkers are important to support the diagnostic and management of dental wear and noncarious cervical lesions.
