Denture‐related characteristics
Denture, denture, mandibular dentures, maxillary dentures
In the pilot study, current denture history was comparable for maxillary and mandibular dentures, with mean denture ages of 11.4 years (SD 12.31 years; range: 1.0–52.0 years) and 12.0 years (SD 12.25 years; range: 1.0–52.0 years), respectively. Fewer (25%) participants with high KO scores at screening were recruited than planned, with 75% having a low KO score; however, sufficient participant numbers were recruited in each subgroup (high or low KO scores) to allow for adequate analysis.In the efficacy study, participants had an average duration of denture use of 23.0 years (SD 19.14 years; range 0.1–63.0 years) for maxillary dentures, and 22.8 years (SD 18.83 years; range 0.1–63.0 years) for mandibular dentures. Current denture history was comparable for maxillary and mandibular dentures, with mean denture ages of 12.3 years (SD 13.57 years; range: 0.1–54.0 years) and 12.2 years (SD 13.54 years; range: 0.1–54.0 years), respectively. No participants had dentures with “poor retention and stability” (<6 Kapur Index total score); 1 (2.1%) had “fair retention and stability” (6–9 total score); 24 (50.0%) had “good retention and stability” (10–14 total score), and 23 (47.9%) had “very good retention and stability” (>14). The mean combined score of 14.8 for the fit assessment (Kapur Index) was indicative of overall very good denture fit and stability at baseline. Denture adhesive was currently being used at screening on maxillary dentures by 17 participants (35.4%) and on mandibular dentures by 20 participants (41.7%).
