About this study

Official title: A Proof of Principle Bite Force Study Using Two New Test Adhesives and a Currently Marketed Denture Adhesive.

The objective of this 4-treatment, 4-period, randomized, crossover, proof of principle bite force study will be to compare bite force measurements over a 12 hour period across two (test) cream denture adhesives, with a currently marketed cream denture adhesive (positive control), and a negative/no treatment control.

Read the detailed description

This will be a 4-treatment, 4-period, randomized, crossover, proof of principle bite force study which will compare bite force measurements over a 12 hour period across two cream denture adhesives with a currently marketed cream denture adhesive (positive control), and a negative/no treatment control. A short questionnaire regarding the flavor and texture characteristics of each denture adhesive after a single use will also be administered to give an indication of participant satisfaction of these attributes.

What is being measured

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

  1. Area Over Baseline Over 12 Hours (AOB0-12) for Test Adhesive 1 Versus (vs.) No Adhesive

    Area over baseline over 12 hours (AOB0-12) was assessed to measure the incisal bite force. AOB0-12 was calculated as area under the curve over 12 hours [AUC0-12])/12 hours minus baseline bite force (pounds [lbs]). AUC0-12 was calculated using the trapezoidal method. This transformation returned the measurement to the same scale as the original observations. Higher values of AOB0-12 demonstrate a stronger bite force overtime than lower values.

    Measured: up to 12 hours

  2. Area Over Baseline Over 12 Hours (AOB0-12) for Test Adhesive 2 vs. No Adhesive

    Area over baseline over 12 hours (AOB0-12) was assessed to measure the incisal bite force. AOB0-12 was calculated as area under the curve over 12 hours [AUC0-12])/12 hours minus baseline bite force (lbs). AUC0-12 was calculated using the trapezoidal method. This transformation returned the measurement to the same scale as the original observations. Higher values of AOB0-12 demonstrate a stronger bite force overtime than lower values.

    Measured: up to 12 hours

Secondary outcomes (3)
  1. Area Over Baseline Over 12 Hours (AOB0-12) for Test Adhesive 1 vs. Positive Control Adhesive

    Area over baseline over 12 hours (AOB0-12) was assessed to measure the incisal bite force. AOB0-12 was calculated as area under the curve over 12 hours [AUC0-12])/12 hours minus baseline bite force (lbs). AUC0-12 was calculated using the trapezoidal method. This transformation returned the measurement to the same scale as the original observations. Higher values of AOB0-12 demonstrate a stronger bite force overtime than lower values.

    Measured: up to 12 hours

  2. Area Over Baseline Over 12 Hours (AOB0-12) for Test Adhesive 2 vs. Positive Control Adhesive

    Area over baseline over 12 hours (AOB0-12) was assessed to measure the incisal bite force. AOB0-12 was calculated as area under the curve over 12 hours [AUC0-12])/12 hours minus baseline bite force (lbs). AUC0-12 was calculated using the trapezoidal method. This transformation returned the measurement to the same scale as the original observations. Higher values of AOB0-12 demonstrate a stronger bite force overtime than lower values.

    Measured: up to 12 hours

  3. Area Over Baseline Over 12 Hours (AOB0-12) for Test Adhesive 1 vs. Test Adhesive 2

    Area over baseline over 12 hours (AOB0-12) was assessed to measure the incisal bite force. AOB0-12 was calculated as area under the curve over 12 hours [AUC0-12])/12 hours minus baseline bite force (lbs). AUC0-12 was calculated using the trapezoidal method. This transformation returned the measurement to the same scale as the original observations. Higher values of AOB0-12 demonstrate a stronger bite force overtime than lower values.
