– The formation of the acquired enamel pellicle is due to the adsorption of salivary proteins to the enamel surface. This adsorption is assumed to be specific and is dependent on the chemical characteristics of the surface. The aim of the present study was to investigate the consistency of the chemical composition of the acquired pellicle collected in vivo. Inter‐ and intraindividual differences in the chemical composition of pellicle material were examined during 2 yr in three different individuals. The amino acid profiles obtained from pellicle analyses were compared to hydrolyzed whole saliva collected at the same time as the pellicle material. The results showed that the amino acid composition of pellicle was consistent both between and within the individuals. The amino acid profiles obtained from the analyses of the saliva samples were different from the pellicle profiles, illustrating the selective nature of pellicle formation. This supports the contention that the adsorption of salivary proteins to dental enamel is a very specific process.
