About this study

Official title: A Clinical Study to Evaluate the Ability of an Experimental Denture Adhesive to Prevent Food Particle Ingress Under Dentures

In this clinical study, an experimental denture adhesive with a precision tip nozzle was tested to evaluate the relative efficacy to reduce the ingress of food under the denture compared to use of no adhesive or a standard marketed adhesive.

Read the detailed description

The aim of this study is to explore the mass of food particle ingress when an adhesive is extruded through the new nozzle with directed application compared to the use of no adhesive and a marketed adhesive (extruded through a flat ribbon nozzle [FRN]) with standard application as per product label, utilizing a peanut occlusion methodology. This was a single center, controlled, single blind (to the examiner performing the safety assessments (oral soft tissue [OST] examination) and the laboratory staff weighing the peanut particles), randomized, three-treatment, three-period, cross-over design in participants with full upper and lower dentures. Each treatment period consisted of one day of testing with at least two days between treatment visits. This study consisted four visits: Visit 1 - Screening Visit; Visit 2 - Treatment 1 Visit; Visit 3 - Treatment 2 Visit and Visit 4 - Treatment 3 Visit.

Being tested
Experimental Denture Adhesive, Reference (Marketed) Denture Adhesive

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Experimental Denture AdhesiveDevice

    Participants received a single application of test denture adhesive with a Flat Ribbon Nozzle as 3 Continuous strips those were applied to upper denture and one continuous strip that was applied to the lower denture which were placed in the mouth.

  • Reference (Marketed) Denture AdhesiveDevice

    Participants received a single application of marketed denture adhesive with a flat ribbon nozzle as a 3 dabs those were applied to upper denture and 2 dabs those were applied to lower denture, which were placed in the mouth.

What is being measured

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

  1. Combined Mass of Peanuts (Gram) (From Upper and Lower Dentures) for Reference Denture Adhesive and on no Adhesive Use

    Participants were provided with 30-32 g (accurately weighed) non-salted peanuts, divided into smaller portions of approximately four whole peanuts. Each portion chewed for approximately 20 seconds. After completion of the peanut consumption, participants rinsed their mouth with water, participants may remove any residual peanut particles from their mouth with water and a gauze pad. Participants than removed their dentures. Peanut particles were collected from the fit surfaces of the dentures and the gauzes, and weighed to evaluate the mass of food particles that had migrated under the denture (keeping the particles associated with the upper and lower dentures separate).

    Measured: Up to 17 days

  2. Combined Mass of Peanuts (Gram) (From Upper and Lower Dentures) for an Experimental Denture Adhesive and Reference Denture Adhesive

    Participants were provided with 30-32 g (accurately weighed) non-salted peanuts, divided into smaller portions of approximately four whole peanuts. Each portion chewed for approximately 20 seconds. After completion of the peanut consumption, participants rinsed their mouth with water, participants may remove any residual peanut particles from their mouth with water and a gauze pad.

    Measured: up to 17 days

  3. Composite Kapur (Olshan Modification) Index Scores for Denture Retention and Stability

    Kapur (Olshan modification) Index score was assessed to examine each denture (upper \& lower) for retention \& stability. Retention was measured as score of 0-5 to assess nature of resistance offered by denture to vertical pull \& lateral force: 5=Excellent;4=Very Good;3=Good;2=Fair;1= Poor;0=No retention. Stability was measured as score of 0-4 to assess nature of rocking offered by denture base on its supporting structures under pressure:4=Excellent (no rocking);3=Good (very slight rocking);2=Fair (slight rocking);1=Poor (moderate rocking);0=No stability (extreme rocking). Composite Kapur (Olshan modification) Index scores was measured as the sum score of retention \& stability for upper or lower dentures separately such that a sum score of zero represents no retention and stability and a sum score of 9 represents excellent retention and stability.

    Measured: Up to 17 days

  4. Kapur (Olshan Modification) Index Scores for Denture Retention

    Kapur (Olshan modification) Index scores were assessed to examine each denture (upper \& lower) for its retention ability. Retention was measured as score of 0-5 to assess nature of resistance offered by denture to vertical pull \& lateral force: 5=Excellent - denture offered excellent resistance to vertical pull and lateral force; 4= Very Good- denture offered very good resistance to vertical pull and lateral force; 3= Good- denture offered moderate resistance to vertical pull and lateral force; 2= Fair- denture offered moderate resistance to vertical pull and little or no resistance to lateral forces; 1= Poor- denture offers slight resistance to vertical pull and little or no resistance to lateral force; 0= No retention- when the denture was seated in place, it displaced itself. Higher the score, higher the retention ability of denture.

    Measured: Up to 17 days

  5. Kapur (Olshan Modification) Index Scores for Denture Stability

    Kapur (Olshan modification) Index scores were assessed to examine each denture (upper \& lower) for its stability ability. Stability was measured using score of 0-4: 4= Excellent- when denture base offered no rocking on its supporting structures under pressure; 3= Good- when denture base had very slight rocking on its supporting structures under pressure; 2= Fair- when denture base had slight rocking on its supporting structures under pressure; 1= Poor- when denture base had moderate rocking on its supporting structures under pressure; 0= No stability- when denture base had extreme rocking under pressure. Higher the score, higher the stability ability of denture.

    Measured: Up to 17 days

Who may be eligible to take part?

The sponsor lists 9 inclusion and 16 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 27 Aug 2018. 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 United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Dec 2017). 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?

Combined Mass of Peanuts (Gram) (From Upper and Lower Dentures) for Reference Denture Adhesive and on no Adhesive Use (time frame: Up to 17 days). 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 27 Aug 2018.
