Identification of acid-resistant proteins in acquired enamel pellicle.

Objectives: This study characterized the proteome profile of the acquired pellicle formed in vivo on enamel. Changes in this proteome profile after exposure to lactic or citric acid were also evaluated.

Methods: Volunteers (n=8) were subjected to dental prophylaxis.

Exposure to acids changes the proteomic of acquired dentine pellicle.

Objectives: For the first time, this study characterized the proteome of the acquired pellicle formed on human dentine. The changes in this proteome after exposure to lactic or citric acid were also evaluated.

Methods: Volunteers (n=9) wore a mandibular device containing 6 specimens of human root dentine.
