Aprašymas

Research Paper (postgraduate) from the year 2010 in the subject Medicine - Dentistry, University of Mosul (Dental college), language: English, abstract: Aims: To evaluate pH, viscosity and retentive ability of modified adhesive materials and compared it with commercially available adhesive materials. Materials and Methods: The pH-value of 0.25% denture adhesive materials were determined using pH meter. The viscosity was determined by Ostwald viscometer (Aldrich Company). The retentive ability was measured by specially manufactured reten-tion testing machine using an acrylic resin disc samples which have 6cm diameter and 3mm thickness prepared from a special mold. Results: The findings of the present study showed that the "Bonyplus" gave the highest pH values of all materials tested. Also, showed that the "CMC" gave the highest vis-cosity values, while "Bonyplus" gave the lowest one. The "CMC" gave the highest retention while the "Distilled water" gave the lowest one. Conclusions: All denture adhesive materials tested have a pH equal to that of neutral. The viscosity test showed that the newly prepared materials have a higher vis-cosity than commercial denture adhesive materials. The retention test showed that the newly prepared materials have a higher efficiency than commercial denture adhesive materials. Key Words: Retentive ability, Properties, denture, adhesive material.
