Abstract The addition of food particles to matrices is a convenient approach that allows steer oral behavior, sensory perception and satiation. aim this study was determine the influence physical-chemical properties heterogenous foods on processing bolus dynamic perception. Bell pepper gel pieces varying in fracture stress concentration were added processed cream cheese differing texture. Addit...

Motivated by the motion of nematode sperm cells, we present a model for the motion of an adhesive gel on a solid substrate. The gel polymerizes at the leading edge and depolymerizes at the rear. The motion results from a competition between a self-generated swelling gradient and the adhesion on the substrate. The resulting stress provokes the rupture of the adhesion points and allows for the mo...

Recently, the use of antioxidants before bonding bleached enamel was considered effective for reversing reduction in bond strength. This article aimed to assess influence different sodium ascorbate (SA) presentations (liquid, gel, and semi-gel) on composite resin–enamel strength after a bleaching protocol. Sound human anterior teeth were collected, cleaned, prepared test, randomly allocated int...

METHOD 1. Immerse the gel, together with its attached glass plate, in 7% acetic acid for 5 minutes. Remove the gel from the fixative by carefully lifting the glass plate from the fluid. 2. Rinse the gel briefly in deionized H2O. Remove excess fluid from the surface of the gel with a pad of Kimwipes. IMPORTANT Do not use absorbent paper; it will stick to the gel. 3. (Optional) Dry the gel onto a...

OBJECTIVE This study investigated the effects of different surface treatments on the tensile bond strength of an autopolymerizing silicone denture liner to a denture base material after thermocycling. MATERIAL AND METHODS Fifty rectangular heat-polymerized acrylic resin (QC-20) specimens consisting of a set of 2 acrylic blocks were used in the tensile test. Specimens were divided into 5 test ...

Mucus is a critical part of the human body’s immune system that traps and carries away various particulates such as anthropogenic pollutants, pollen, viruses, etc. Various synthetic hydrogels have been developed to mimic mucus, using different polymers their backbones. Common these simulants three-dimensional gel network physically crosslinked capable loosely entrapping water within. Two challe...

This paper puts forward a novel non-ionic augmentation system, namely, gelation of native starch in the presence of borax and papermaking fibers. Native starch was blended with high concentration pulp and auxiliary agents. After pasting, the starch gel adhered onto fiber surfaces. However, an excess dosage of agents led to a rigid structure and poor gel strength. Starch became gelatinized and t...

PURPOSE The purpose of this investigation was to compare the pain responses of children during local anesthetic infiltration at bilateral palatal sites prepared with the topical application of benzocaine 20% oral adhesive (Orabase-B) versus benzocaine 20% gel (Hurricaine) or EMLA 5% oral adhesive (EMLA 5% cream in Orabase Plain). METHODS Forty subjects, aged 7-15 years old, received bilateral...

No previous study has clarified the experience of using adhesives/moisturizers by comparing them to subjective evaluations of patient satisfaction. In an ultra-aged society, most elderly individuals experience many oral problems. Particularly, xerostomia and mal adaptation to dentures may lead to poor retention of maxillary complete dentures. Many patients use denture adhesives; however, the ef...
