Clinical Trial Summary

To compare the retentive strength of different form of commercially available denture adhesives (paste, powder and cushion) on different form of residual ridges. To evaluate the effect of various denture adhesives on efficiency of complete dentures in patients with different alveolar ridges.


Clinical Trial Description

- Prior approval from ethical committee has been taken (Annexure-D) - As per protocol all patients presenting will be examined in general opd and those patients in need of rehabilitation of their missing teeth will be referred to Prosthodontics dept. - Patients will undergo history and complete oral examination after informed consent (Annexure-B). On the basis of these information the patient will be selected for the study acc to exclusion and inclusion criteria. - The patients will then categorized into three groups based on clinical and radiographic features of ridges according to Wical-Swoope classification. - A well-constructed denture will be fabricated and all the post op complaints will be resolved. - Three forms of denture adhesives will be used including powder, cream and strips for all three resorption classes as described by Wical-Swoope. - A digital spring scale will be used to record the reading , All the measurements will be recorded in grams - Retentive strength will be recorded first before application of the adhesives for baseline retention strength. - Patient with denture in his mouth will be instructed to maintain max non-forced intercuspation for fives minutes. Atfer that with mouth opened and lower lip relaxed in order to avoid losing peripheral seal tip of the spring scale will be placed at the margin of denture in recess to lingual frenum. Traction forced will be then applied until denture is detached, the max retention force being recorded by sping scale. This procedure will be repeated thrice and mean value will be calculated. - A second reading will be recorded after application of adhesive in similar manner - Mean increase in denture retention strength will be calculated by subtracting denture retention strength without adhesive from denture retentive strength with adhesive for both study products - The scores calculated will be filled in Performa (annexure-A) - The obtained data will be then used to compare diff form of commercially availble denture adhesives (pastes, powder and cushion) for their mean increase in retention strength. - Then patient will be instructed about how to apply denture adhesives (based on manufacturer' instructions) - The patient will fill out two attributed questionnaires, before and 1 week after using the denture adhesive. In the questionnaire the satisfaction rating will be determined using valid questionnaires with seven evaluation items: general satisfaction, ability to speak, ease of cleaning, stability, retention, comfort and mastication performance (VAS? Likert scale?) - The quantitative variable, age of the patients and retention strength was presented as mean+- SD. The qualitative varaible like sex was presented as frequency and percentages. T-test was used to determine the existence if difference of mean retention strength b/w the two form of denture adhesives. - Data were analyzed using ANOVA and Chi-square tests in SPSS software version 25 software (SPSS version 25.0, SPSS Inc; Chicago, IL, USA) (P<.05) The score calculated will be filled in the performa (Annexure-A) ;
