Clinical Evaluation of Denture Adhesive Efficacy at Preventing Food Ingress
Objectives: Denture adhesives are recommended to denture wearers, to increase the retentive hold of dentures to the oral mucosa, and to reduce the ingress of food particles under the denture. This study’s objective was to evaluate the effectiveness of a novel marketed denture adhesive in minimising food particle migration under dentures whilst eating, by objectively quantifying food ingress.
Methods: This was a single-centre, controlled, single-blind, randomized, two-treatment, two-period cross-over clinical study, in subjects with well-fitting full maxillary and mandibular dentures. Subjects wore both their dentures whilst chewing peanuts in a prescribed manner. Dentures were removed, and peanut particles collected from the fit surfaces of the dentures and the underlying supporting soft tissues. The collected peanut debris was washed, dried and weighed. Subjects used either denture adhesive or no adhesive in a crossover manner. Adhesive was applied via a precision applicator as thin continuous beads along the maxillary denture ridge, with two strips applied in the palatal area (1.0±0.1g) and along the depth of the mandibular denture ridge (0.6±0.1g). A subjective questionnaire based on chewing experience was also administered to subjects.
Results: The combined mass of peanut particles under maxillary and mandibular dentures was significantly lower (p<0.0001) with the use of adhesive (Geometric mean/GM=5.56mg) compared to no adhesive (GM=29.13mg). The assessment of subject’s responses to the questionnaire favoured the adhesive; 75.0% of subjects using adhesive were not aware of peanuts food particles under their dentures compared to 31.3% using no adhesive.
Conclusions: This study demonstrated that the tested adhesive is effective in minimising food ingress, with a greater than 5-fold reduction in peanut ingress under dentures with adhesive use compared to no adhesive. These objective results are supported by the subject-perceived benefits, with favourable subjective responses to questionnaire assessments of the effects of food ingress associated with denture adhesive use.
