The aim of this study is to evaluate the use of a denture adhesive and its ability to demonstrate the improvement in overall gum-health and to improve the oral health related quality of life (OHrQoL) in participants who wear full dentures.
This study will be a single center, controlled, single-blind, randomized, two-treatment, parallel design in healthy participants with a full conventional, acrylic denture in either or both dental arches, with a treatment period of 12 weeks. The study will assess the effectiveness of an experimental denture adhesive in the improvement of denture-bearing tissue irritation related measures, and the participant's oral health related quality of life. Participants will be randomized to one of the 2 treatment groups i.e. experimental denture arm group and control arm group and will undergo an oral soft tissue (OST) examination. Participants with satisfactory dentures, adequate retention and stability and who qualify all the inclusion and exclusion criteria will continue in the study. Participants will complete the Gum Comfort, OHIP-Edent questionnaires and GOHAI questionnaire. The assessments will be made at Baseline, and after 1, 4, 8 and 12 weeks treatment.

| Gum Health Analysis by Change From Baseline in Overall Mean Scores of Participant Responses to the Gum Comfort Questionnaire After 12 Weeks | Gum comfort questionnaire was referred to assess the gum health of the denture wearer and to compare the ability of an experimental denture adhesive to provide self-perceived mucosal benefits compared to the use of no adhesive after 12 weeks of product use. It was comprised of 5 questions- Q1: My gums feel comfortable when wearing my denture(s), Q2: I feel my gums are cushioned from the impact of chewing and biting; Q3: My gums do not feel sore at the end of the day; Q4: My gums are not irritated by trapped food particles under my denture(s); Q5: My gums do not feel tired at the end of the day. The participants recorded the response on scale of 0-4: 0-Agree Strongly, 1-Agree Somewhat, 2-Neither Agree or Disagree, 3-Disagree Somewhat, 4- Disagree Strongly). Total score range is 0-20 where lower score indicated better results. | At Baseline and after 12 weeks |
