“…A rapid absorption of salivary components (pellicle formation) is the initial process in bacterial adhesion and subsequent plaque accumulation (Quirynen & Bollen 1995;Steinberg et al 1998). The omnipresent formation of a pellicle in vivo reduces bacterial adhesion considerably irrespective of the underlying substratum, and has a masking effect on materials' specific surface characteristics (Morge et al 1989;Siegrist et al 1991). Apparently, surface properties influenced only early bacterial adherence, but not plaque maturation; the specificity of adsorption process onto substrata with different physical properties is assumed to be only lost progressively (Oste et al 1981;Hannig & Hannig 2009).…”

“…Whereas covalent binding of salivary components after adsorption is discussed for mucosal surfaces [3,4], the formation of a layer of salivary proteins on teeth as well as on dental materials is based on noncovalent binding. Therefore, the nature of the substrate may influence the composition of the pellicle [17,34], and the formation of a pellicle in turn may mask the surface properties of the dental materials [24]. For example, Carlén et al [7] found more of the bacteria-binding salivary proteins, e.g., agglutinin, proline-rich proteins, and low-molecularweight mucin MG2 on unpolished glass ionomer than on unpolished composite resin specimens.…”

The formation of a salivary pellicle is a protective mechanism of the body for all surfaces in the oral cavity. The nature of the substrate may influence the composition of the pellicle. The aim of this study was to investigate the quantitative composition and individual variation of the salivary pellicle formed on denture base material (PMMA). Cylindrical specimens of PMMA were carried in the mouth and then desorbed with a 0.5-M sodium chloride solution. The solution was analysed for total protein, alpha-amylase, total proteases, protease inhibitors, secretory immunoglobulin A, immunoglobulin G, peroxidases, thiocyanate, lysozyme, and calcium content. All investigated salivary components could be found unequivocally in the desorption solution, indicating that a salivary pellicle had formed on the surface of the PMMA. Large coefficients of variation indicate large individual variations in the adsorbed amounts. The data also point to large intraindividual variations for the bound salivary components. Only the protease inhibitors revealed a strong positive correlation of the bound activity to the salivary activity. It is hypothesised that differences in the bound amounts of antimicrobial components might influence the microbial colonisation of denture bases and that protease inhibitors could be meaningful for the spread of the yeast Candida albicans from denture base material to the oral mucosa and thus might be an explanation for different susceptibility to denture base stomatitis.

“…Despite the fact that fresh amalgam has high surface tension 22 , which affects negatively the wettability of the surface, composite resin was inserted after only 5 min in order to mimic clinical conditions. This approach seems to be time saving and the use of a temporary restoration over the placed amalgam is avoided.…”

Aim: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. Methods: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of pulpal floor. Dental tissues were etched with 37% acid and a bonding agent (Bond 1-SF, Pentron) was applied and cured. Composite resin (Filtek Z250, 3M-ESPE) was placed in layers in the mesial proximal box and occlusally, and light cured. Marginal adaptation was evaluated at the following interfaces: amalgam-tooth (A), amalgam-composite resin (AC) and composite resin-tooth (C). Microleakage was evaluated by means of methylene blue infiltration after 7-day water storage and thermocycling regimen (1500 cycles). Microleakage was assessed as percentage depth of horizontal dye penetration. Results: ANOVA showed statistically significant difference between A-AC and A-C (p<0.01). No statistically significant difference was found between AC-C interfaces (p>0.05). Mean microleakage values were A (73.529/28.71), AC (34.118/34.6) and C (40.435/ 34.965), according to Tukey's test. Conclusions: Although the bonding mechanism between amalgam and composite has not yet been completely explained, amalgam/composite resin interface exhibited the lowest microleakage scores. Since amalgam/composite resin restorations exhibited lower microleakage scores than composite resin on the cervical surface, combined restorations can be considered as a biological and aesthetic alternative to conventional Class II composite or amalgam restorations.
