Taste disorders following cancer treatment: report of a case series.

Purpose: To present the findings of combined oral assessment and gustometry testing of a series of head and neck and hematologic malignancies in patients with self-reported taste change after cytotoxic therapies.

Methods: Patients with acute myeloid leukemia (AML), multiple myeloma (MM), and head and neck cancer (HNC) were evaluated for taste function. Chemical gustometry was conducted assessing chemosensory qualities that included sweet, sour, salty, bitter, umami, and spicy.

Permeability of Dental Adhesives - A SEM Assessment.

Objectives: To morphologically evaluate the permeability of different commercial dental adhesives using scanning electron microscopy.

Methods: SEVEN ADHESIVE SYSTEMS WERE EVALUATED: one three-step system (Scotchbond Multi-Purpose - MP); one two-step self-etching primer system (Clearfil SE Bond - SE); three two-step etch-and-rinse systems (Single Bond 2 - SB; Excite - EX; One-Step - OS); and two single-step self-etching adhesives (Adper Prompt - AP; One-Up Bond F - OU). The mixture of primer and bond agents of the Clearfil SE Bond system (SE-PB) was also tested.

Influences of surface and solvent on retention of HEMA/mixture components after evaporation.

Objectives: This study examined the retention of solvents within experimental HEMA/solvent primers after two conditions for solvent evaporation: from a free surface or from dentine surface.

Methods: Experimental primers were prepared by mixing 35% HEMA with 65% water, methanol, ethanol or acetone (v/v). Aliquots of each primer (50 microl) were placed on glass wells or they were applied to the surface of acid-etched dentine cubes (2mm x 2mm x 2mm) (n=5).

Effect of an additional hydrophilic versus hydrophobic coat on the quality of dentinal sealing provided by two-step etch-and-rinse adhesives.

Objective: To test the hypothesis that the quality of the dentinal sealing provided by two-step etch-and-rinse adhesives cannot be altered by the addition of an extra layer of the respective adhesive or the application of a more hydrophobic, non-solvated resin.

Material And Methods: full-crown preparations were acid-etched with phosphoric acid for 15 s and bonded with Adper Single Bond (3M ESPE), Excite DSC (Ivoclar/Vivadent) or Prime & Bond NT (Dentsply). The adhesives were used according to the manufacturers' instructions (control groups) or after application to dentin they were a) covered with an extra coat of each respective system or b) coated with a non-solvated bonding agent (Adper Scotchbond Multi-Purpose Adhesive, 3M ESPE).

Effects of a combined application of potassium oxalate gel/adhesive agent on dentin permeability in vitro.

Purpose: To test the effects of sequential application of potassium oxalate gel/adhesive agent on in vitro dentin permeability.

Materials And Methods: Full crown preparations were made in extracted human molars to expose deep coronal dentin. The roots and pulp were removed and the resulting crown segments were connected to a special device (Flodec) to permit the measurement of the permeability of the specimens before and after treatments.
