Comparison of retention of powder and paste form of denture adhesives in mandibular complete denture wearers by using spring scale

After informed consent participants will be divided into group A (powder denture adhesive) and group B (paste denture adhesive) by lottery method. Paper slips, each labeled with either group A or group B will be placed in a jar. Patients will be asked to randomly select one slip from the jar, and the content of the slip will determine their group assignment. This lottery method will ensure that each patient had an equal chance of being assigned to either group, eliminating bias in the group allocation process. All patients will be blinded to this group allocation. In order to minimize bias and ensure objective measurements, the data collection procedure will involve the participation of two investigators and a principal investigator. The first investigator, under supervision of principal investigator, will be responsible for application of denture adhesive and proper seating of complete denture in patient’s mouth. This setup allows for consistent application across all participants, reducing the potential of variability. The second investigator, also under the supervision of principal investigator, will be responsible for measuring the denture retention using spring scale. The second investigator will be blinded to the type of adhesive applied to maintain objectivity in the measurement process. The principal investigator will oversee the entire study and observe both investigators to ensure adherence to protocol and prevent any potential biases. Group A patients’ measurement of denture retention without any denture adhesive application with Spring scale will serve as control value. Powder denture adhesive will be applied by first investigator as per manufacturer’s instruction and patient will be instructed to maintain non-forced intercuspation (bite) for 5 minutes. The second investigator will measure the denture retention by using spring scale and record it. Two additional measurements will be taken after 1 minute interval in order to eliminate error. Mean of these three retention measurements will be calculated to obtain a representative value for each patient. Same steps i.e. control measurements, adhesive application, non-forced intercuspation and retention measurements will be followed using the paste denture adhesive on patients of group B. All investigators are prosthodontists
