Plain-language summary
This study aims to evaluate and compare the influence of different denture cleansing methods using 1% sodium hypochlorite solution, 0.2% chlorhexidine solution and effervescent alkaline peroxide tablet solution -according to manufacturer's instructions- on surface roughness , microhardness and dimensional stability (%) of CAD-CAM Milled both Polymethyl methacrylate and Polyether Ether Ketone denture base materials.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Used prefabricated CAD-CAM blocks (PMMA and PEEK, dental grade)
* All specimens milled using standardized CAD-CAM protocols
* Materials from same brand, batch and shade per group
* All specimens polished to a clinical high gloss standard
* Used standardized specimen geometry
Exclusion Criteria:
* Specimens fabricated using a method other than CAD-CAM milling
* Use blocks from different manufacturer, batches or shades within the same test group
* Use specimens with fabrication defects (visible porosity, cracks, internal voids) or obvious milling errors (tool chattering marks, incomplete milling)
* Specimens with dimensional inaccuracy
* Specimens subjected to incorrect immersion time, temp or concentration of disinfectant
* Use contaminated, not freshly prepared or expired disinfectant solutions
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
