A Study to Evaluate the Retentive Ability of Different Denture Adhesive Materials: An In Vitro Study

Denture Adhesives are commonly used by denture wearers to enhance the retentive ability of their dentures however, little is known about the efficacy of these materials. To compare the retentive ability of three different commercially available denture adhesives. To find out the best available denture adhesive material. An in vitro investigation to evaluate the retentive ability of three commercially available denture adhesive powders and two adhesive pastes was conducted. The adhesion and cohesion that developed between the glass surface and acrylic resin samples when the various materials were interposed between them was evaluated by means of a testing apparatus. Denture adhesives increase the adhesion of resin samples to the glass surface. Fixon powder showed the highest resistance to dislodgement. The paste forms were found to be more retentive. Denture adhesives when used in combination with synthetic saliva showed the maximum value

Quantification of stimuli

— In the experimental setting where pain or discomfort is elicited, it is imperative that the different types of stimuli used (i.e., chemical, mechanical, thermal, and electrical) be quantified and other important factors be considered: (1) reproducibility of the stimulus, which depends upon its ability to be completely characterized and exactly measured; and (2) control of potential modifying factors winch might influence the pain threshold. Thus, the stimulus must be measurable, reproducible, and behaviorally predictable.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74421/1/j.1600-9657.1986.tb00603.x.pd
