Evidence is provided from studies on natural and artificial biofluids that the sequestration of amorphous calcium phosphate by peptides or proteins to form nanocluster complexes is of general importance in the control of physiological calcification. A naturally occurring mixture of osteopontin peptides was shown, by light and neutron scattering, to form calcium phosphate nanoclusters with a cor...

Individuals vary largely in their salivary flow and composition, and given the importance of saliva on perception of taste, this might influence how the tastant stimuli are perceived. We therefore hypothesise that altering the individual salivary flow rates has an impact on the perceived taste intensity. In this study, we investigated the role of saliva amount on the perceived taste intensity b...

Dentures which included a reservoir for dispensing artificial saliva were constructed for a trial group of patients with oropharyngeal cancer seen in the postirradiation period. The tumors were apparently under control, but the patients were suffering from xerostomia. Details of the design, construction, and use of such a device are presented. The subject of postirradiation xerostomia in the ed...

UNLABELLED The longevity and durability of composite resins are influenced by the actions of water, saliva, drinks, food and features of the oral environment. OBJECTIVE The aim of this study was to evaluate the effect of mouthwashes containing alcohol on the surface hardness, sorption and solubility of composite resins. METHODS Disc-shaped specimens were prepared with two composite resins Z...

Abstract Reducing the friction force between commercial archwire and bracket during orthodontic treatment in general dental practice has attracted worldwide interest. An investigation on wear behaviors of uncoated carbon film coated stainless steel archwires running against brackets was systematically conducted. The films were prepared at substrate bias voltages from +5 to +50 V using an electr...

Aim: To evaluate the effect of different oral media (artificial saliva, carbonated orange juice and coffee) on surface roughness color stability 3D printed temporary material. Methodology: Twenty one discs samples were designed using additive manufacturing technique (SLA) divided into 3 groups stored in artificial coffee at 37 ℃. Surface was measured before after immersion non-contact USB Digit...

OBJECTIVES The aim of this investigation was to give insights into the impact of carbohydrate-electrolyte drinks on the likely capacity of enamel surface dissolution and the influence of human saliva exposure as a biological protective factor. MATERIALS AND METHODS The pH, titratable acidity (TA) to pH 7.0, and buffer capacity (β) of common beverages ingested by patients under physical activi...

The aim of this study is to assess the in vitro shear bond strength and adhesive remnant index (ARI) of one and two-step fluoridated orthodontic resins under conditions that simulate high cariogenic challenge. Edgewise brackets for maxillary central incisors were randomly bonded to 80 bovine incisors, using either Transbond Plus Color Change orthodontic resin and a self-etching primer adhesive ...
