A Study to Investigate a Method to Measure Food Occlusion by Denture Adhesives in Denture Wearers

March 27, 2019 updated by: GlaxoSmithKline

A Randomized, Open-Label, Clinical Study to Evaluate a Methodology to Assess Food Occlusion Efficacy of a Denture Adhesive in Healthy, Edentulous Subjects

The purpose of this study is to evaluate a methodology to determine the ability of a denture adhesive to restrict food ingress underneath dentures during eating.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This will be a single centre, controlled, open label, randomized, three-treatment, three-period, cross-over design in participants with full upper and full lower dentures. Each treatment period will consist of one day of testing with at least two days between adjacent treatment visits. This study will consist of four visits: Visit 1 - Screening Visit; Visit 2 - Treatment 1 Visit; Visit 3 - Treatment 2 Visit and Visit 4 - Treatment 3 Visit. (Participants will use Test product (denture adhesive) applied to the dentures either in a pattern consistent with standard application or applied to the dentures in a pattern of continuous strips. Participants will also use no adhesive as a control. Participants will cross-over between treatments so that all participants will participate in all 3 treatment arms. An hour after the participant has worn their denture, they will chew a portion of peanuts in a controlled manner. The peanuts that migrate under the denture during this chewing procedure will be collected, washed, dried and weighed. Participant will also answer a short questionnaire on the procedure and record the number of times their denture dislodged during the chewing procedure. The study hypothesis is that this methodology will enable comparisons between denture adhesives and no adhesive to demonstrate the effectiveness of denture adhesives at restricting food ingress under dentures during eating.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Participation in any other clinical study involving investigational drugs, cosmetics or medical devices within 30 days prior to study entry and/or during study participation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mass of Peanuts Under Combined Maxillary and Mandibular Dentures (Denture Adhesive Applied Per Conventional Pattern)
Time Frame: Upto 9 weeks
Participants received 1.6 grams (g) of test adhesive on their dentures in a conventional pattern. After 60 minutes (min), participants were provided with 30-32 g non-salted peanuts, divided into smaller portions of approximately eight peanut halves. Each portion chewed for approximately 20 seconds (s). After consumption of all peanuts, participants had rinse their mouth with water for approximately 5 s. Dentures were removed and any peanuts remaining in the mouth were collected using a gauze. Both denture and gauze were placed in a beaker with hot de-ionized water and sonicated for 30 minutes (min) after which the water was strained through a standard testing sieve. The collected particles were washed and air-dried and transferred to pre-weighed aluminium weighing pans using a spatula and then, were dried in an oven at 40-degree Celsius for 5 hours. The pans were removed, cooled to room temperature and then weighed to determine the mass of the particles collected from each denture.
Upto 9 weeks
