Chemical Analysis of the Acquired Pellicle Formed in Two Hours on Cleaned Human Teeth in vivo

Abstract: A method for the collection of the proteins film formed on pumiced teeth in vivo is described. The amount of adsorbed protein increased during the first 1.5 h. No differences were detected in amino acid composition of protein collected from upper molars, upper incisors, and lower anteriors. Muramic acid and diaminopimelic acid were not detected. The content of acidic amino acids in the material may support the view that acidic proteins are selectively adsorbed to tooth surfaces.

“…The overall character of the pellicle has been reported to be anionic [15]. Since cationic proteins like lactoferrin, lactoperoxidase, lysozyme and histatins have been identified in the pellicle it can be hypothesized that these antimicrobial proteins may enhance the protective functions of the pellicle.…”

“…As several of these proteins have shown to retain their antimicrobial activity when adsorbed to surfaces [5,9,10], they are believed to contribute to the protective functions of the pellicle. Further, the overall character of the pellicle has been reported to be anionic [11], and the presence of these cationic components may increase the cohesiveness and thickness of the film by complex formations with anionic pellicle proteins. This study is a complement to a preceding, more detailed study performed on the adsorption behaviour of lactoferrin, lactoperoxidase, lysozyme and histatin 5, that investigated the adsorption in terms of concentration dependence, influence of surface wettability, kinetics and elutability by buffer and surfactant solutions [12].…”

“…Isto é acompanhado por uma fase secundária, comparativamente mais lenta de adsorção de proteínas na superfície do dente revestida por proteínas (JONER et al, 2008;NAUNTOFTE;TENOUVO;LAGERLÖF, 2007). A espessura da película aumenta rapidamente dentro de 30 minutos, atingindo um patamar após 90 minutos JOINER et al, 2008;SKJORLAND;RYKKE;SONJU, 1995;ROLLA, 1973). A espessura desta camada inicial alcança em média 10-20 nm BALZ, 1999;.…”

“…Várias publicações consideram que a espessura da película atinge o equilíbrio entre a adsorção e dessorção e que a mesma está completamente formada dentro de 2 horas (LENDENMANN; GROGAN;OPPENHEIM, 2000;SKJORLAND;RYKKE;SONJU, 1995;ROLLA, 1973). Este processo de maturação é necessário para transformar uma película recém-formada em uma película capaz de proteger os dentes contra a desmineralização (LENDENMANN; GROGAN;OPPENHEIM, 2000;STIEFEL, 1976 Proteínas salivares que exibem uma elevada afinidade por hidroxiapatita constituem as chamadas "proteínas precursoras da película" (LENDENMANN; GROGAN;OPPENHEIM, 2000).…”
