“…A first group comprises the actual adhesives, including a broad range of classical products such as plant gums (karaya, tragacanth, acacia), and more recent components based on natural (methylcellulose, hydroxymethyl cellulose, carboxymethyl cellulose) and synthetic polymers (polyethylene oxide, arcylamides, polyvinyl acetate) (3). A second group of materials comprises antimicrobial agents such as sodium borate, sodium tetraborate, hexachlorophene or propylhydroxybenzoate and ethanol (4). These substances act as preservatives and are moderately active against Candida albicans.…”

Statement of problem: One of the main problems posed by complete dentures is retention and stability. In order to solve this problem, dentists and the dental industry for a long time have attempted to improve denture adhesion by developing a range of "glues" of highly varied composition and efficacy. Purpouse: The present in vivo clinical study evaluates whether the adhesives used to improve complete denture retention are truly effective and able to increase denture adhesion to the mucosa covering the edentulous alveolar ridge of the mandibular dentures. Material and Methods: An in vivo clinical study is made of 30 patients with complete mandibular dentures to evaluate the retention afforded by three commercial complete denture adhesives (Benfix . A spring scale was used to measure retention strength (in grams). The purpose was to determine whether the use of complete denture adhesives is effective, and to establish which commercial brands offer the highest retention strengths. Results and Conclusion:The results obtained indicate that retention is enhanced by the use of such adhesives, and that Fittydent® offers the best retention performance, followed by Benfix® and Supercorega ® .Clinical implications: the study of denture adhesives and his efficiency are necessary to improve the edentulous patient satisfaction. More in vivo investigations are necessary in dental literature.

“…These findings are similar to those detected in studies carried out by Rice and Gates. 9,11,7 Staphylococcus aureus (1.8%) and Aspergillus (1.8%) which are moderately virulent organisms were also isolated and have been documented as a cause of infection in immunocompromised patients. 13 Similar findings were seen in studies by Rice, Powell and Montgomery who found these organisms in less than 1% of the samples.…”

Aim: To evaluate factory-sealed containers of three different commercially available irreversible hydrocolloid impression materials for their microbial contamination and the type of microorganisms present. Materials and methods:Thirty-six measured samples were taken of each brand and placed on chocolate agar plates or in thioglycolate broth tubes and were incubated along with appropriate parallel controls. After incubation, colonies were enumerated and identified using standard microbiological methods.

“…3 aluminium lake, and l-menthol are added as antiseptic, pigment, and flavor factors, respectively. Previous studies investigated the basic properties of cytotoxicity [14][15][16] and microbial contamination 17) of denture adhesives. On the other hand, the adhesion strength of denture adhesives is an important factor, as it directly influences retentive force between the denture and denture-bearing mucosa.…”

We evaluated adhesion strength to acrylic resins under various experimental conditions and viscosity of 4 cream-type denture adhesives and 2 mouth moisturizers. The viscosity was determined by a sine-wave vibro viscometer. The adhesion strength tests were performed with 2 resin plates at a universal tester. In Method A, various constant thicknesses of material layer were tested and tensile strength was measured, while in Method B a constant load was applied before measurement. Five tests were carried out for each measurement. With Method A, adhesion strength increased exponentially as the layer got thin. Effect of the material thicknesses (contribution ratio ρ=79.0%) was much larger than that of material type (ρ=15.3%). Materials with higher viscosity had greater levels of adhesion strength in Method A, whereas those with the higher viscosity had lower levels of adhesion strength in Method B. Adhesion strength was significantly affected by the experimental condition prior to applying tension.
