Amino-acid Composition of the Acquired Pellicle of Human Tooth Enamel

Lubrication and load-bearing properties of human salivary pellicles adsorbed ex vivo on molecularly smooth substrata

“…The layer has been observed on tooth enamel (Meckel 1965;Armstrong 1966), artificial dental materials (Sipahi et al 2001) and soft oral tissues (Bradway et al 1992;Pramanik et al 2010). The acquired enamel pellicle, in particular, has been the subject of considerable dental (Proctor et al 2005), biochemical (Al-Hashimi and Levine 1989), microscopic (Lie 1977;Hannig et al 2001) and surface chemistry (Sipahi et al 2001) study (references are examples).…”

Concerning Dental Plaque

“…In any case, its ultimate fate under old established 'plaques' or in areas where there has been surface change in the enamel seems to be unknown. Histo-chemical [18,19,24] and chemical studies [1,22] of pellicle have not given consistent results in the hands of different investigators, which suggests either that its composition differs in different tooth areas or varies with time on the same surfaces. Differences in chemical composition of the proteinaceous material layering on the enamel surface could be accounted for by the ability of enamel to adsorb proteins of various sorts.…”

“…It can reasonably be expected that there will be developments on the tooth surface resembling plaque formation on monuments [1] patination of flints [2] or the formation of biochemically labile colloidal-bacterial films [3] like those occurring on soil particles. These could function in either a pro tective or destructive manner.…”

Adsorption to Hydroxylapatite of Proteins and Conjugated Proteins from Human Saliva

“…These cuticles have been classified according to mor phological appearance and their chemical composition (c.f. Schüle, 1962;Meckel, 1965;Armstrong, 1966) has been studied with respect to amino acids and carbohydrates.…”
