About this study

Official title: A Randomized, Single-blind, Efficacy Study to Evaluate Oral Health and Quality of Life Associated With Use of a Denture Adhesive

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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: At Baseline and after 12 weeks

  3. Mucosal Health Analysis of Denture Bearing Tissues by Change From Baseline in Mucosal Score Assessment (MSA) After 1, 4, 8 and 12 Weeks

    MSA used by dentist to assess health of denture bearing tissues of participants across whole mouth on scale:1-4,1- normal appearance of gingiva,oral mucosa,2-mild inflammation(slight redness and/or hypertrophy/hyperplasia of gingiva and slight redness in some areas of palatal mucosa,including red spots indicating inflamed salivary duct orifices),3-moderate inflammation(marked redness and hypertrophy/hyperplasia of the gingiva, in large ares of palate, in oral mucosa, ulceration caused by denture, red and inflamed fibro-epithelial hyperplasia caused by denture),4-severe inflammation(severe redness and hypertrophy/hyperplasia of gingiva,spontaneous gingival bleeding, marked palatal granulations, inflamed oral mucosa areas).MSA was performed on denture-bearing tissues for either/both dentures across whole mouth and examiner recorded highest applicable score. Lower score indicated better results.

    Measured: At Baseline and after 1 week, 4 weeks, 8 weeks and 12 weeks

  4. Oral Health Related Quality of Life (OHrQoL) Analysis by Change From Baseline in Overall Mean Scores of Participant Responses to the Oral Health Impact Profile for Edentulous Patients (OHIP)-Edent Questionnaires After 1, 4, 8 and 12 Weeks

    OHIP-Edent questionnaire was used for the evaluation of OHrQoL. This questionnaire was comprised of 19 questions grouped into 6 functional domains and the participants responded on the scale of 0-4: 0-never, 1-rarely, 2-occasionally, 3-often and 4-very often. The functional domains are: domain 1- functional limitations (questions 1-3, score range 0-12), domain 2- physical pain (questions 4-7, score range 0-16), domain 3- psychological discomfort (questions 8-9, score range 0-8), domain 4- physical disability (questions 10-12, score range 0-12), domain 5- psychological disability (questions 13-14, score range 0-8) and domain 6- social disability (questions 15-19, score range 0-20). The overall score range is 0-76 where 0 is the best possible score. Lower scores represent a more favorable perception of participants OHrQoL.

    Measured: At Baseline and after 1 week, 4 weeks, 8 weeks and 12 weeks

  5. OHrQoL Analysis by Change From Baseline in Average Domain Scores of Participant Responses to the OHIP-Edent Questionnaires After 1, 4, 8 and 12 Weeks

    OHIP-Edent questionnaire was used for the evaluation of OHrQoL. This questionnaire was comprised of 19 questions grouped into 6 functional domains and the participants responded on the scale of 0-4: 0-never, 1-rarely, 2-occasionally, 3-often and 4-very often. The functional domains are: domain 1- functional limitations (questions 1-3, score range 0-12), domain 2- physical pain (questions 4-7, score range 0-16), domain 3- psychological discomfort (questions 8-9, score range 0-8), domain 4- physical disability (questions 10-12, score range 0-12), domain 5- psychological disability (questions 13-14, score range 0-8) and domain 6- social disability (questions 15-19, score range 0-20). The overall score range is 0-76 where 0 is the best possible score. Lower scores represent a more favorable perception of participants OHrQoL.

  6. OHrQoL Analysis by Change From Baseline in Overall Mean Scores of Participant Responses to the General Oral Health Assessment Index (GOHAI) Questionnaires After 1, 4, 8 and 12 Weeks

    GOHAI questionnaire was used for the evaluation of OHrQoL. It was comprised of 12 questions with 6 possible responses. The participants responded on the scale of 0-5: 0-always, 1-very often, 2-often, 3-sometimes, 4-seldom and 5-never. The functional domain of the questionnaire are as: domain 1: functional (questions 1-4, score range 0-20, participant's ability to eat, speak and swallow); domain 2: psychological (questions 6,7,9-11, score range 0-25, participant's concerns, relationships and appearance); domain 3- pain/ discomfort (questions 5,8,12, score range 0-15, participant's discomfort during chewing, sensitivity to hot/cold/sweets and use of medications to manage oral pain). The responses were scored on a 0 (always)-5 (never) scale for all questions except 3, 5 and 7 where the scoring is reversed, and thus the range of scores for the questionnaire is 0-60, where 60 is the best possible score. Higher score indicated better results.

    Measured: At Baseline and after 1 week, 4 weeks, 8 weeks and 12 weeks

  7. OHrQoL Analysis by Change From Baseline in Average Domain Scores of Participant Responses to the GOHAI Questionnaires After 1, 4, 8 and 12 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Experimental Denture Adhesive in people with Denture Retention, run by GlaxoSmithKline at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 May 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gum Health Analysis by Change From Baseline in Overall Mean Scores of Participant Responses to the Gum Comfort Questionnaire After 12 Weeks (time frame: At Baseline and after 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2021.
