Post-endodontic Access Cavity Cleaning Techniques

Turkey (Türkiye)70 participantsStarted 2024-08-19

Plain-language summary

Aim This study aims to evaluate the effectiveness of different post-endodontic access cavity cleaning techniques (PACCTs) in removing residual epoxy resin-based root canal sealer from the pulp chamber floor following root canal treatment. The cleaning efficacy of seven different protocols, including manual and mechanically-assisted methods, will be compared based on the reduction of sealer-covered area (SCA). Study Design / Methodology This study is designed as a prospective, single-center, randomized clinical trial with parallel group design. A total of 70 patients who require root canal treatment in maxillary first molars will be included in the study. Patients will be randomly assigned to seven experimental groups (n=10 per group) according to the cleaning technique used after root canal obturation with AH Plus epoxy resin-based sealer. The cleaning protocols will be: 1. Dry cotton pellet (control group) 2. Ethanol-saturated cotton pellet (7 sec) 3. Ethanol-saturated cotton pellet (visibly clean) 4. Ethanol-saturated cotton pellet + air polishing 5. Ethanol-saturated microbrush (7 sec) 6. Ethanol-saturated microbrush (visibly clean) 7. Air abrasion Standard root canal treatment procedures will be performed in all groups using rotary instrumentation and cold lateral condensation technique for obturation. The cleaning effectiveness will be evaluated using standardized high-resolution macro photographs taken before and after the cleaning procedures. The sealer-covered area (SCA) will be calculated using image analysis software (Adobe Photoshop) based on pixel analysis. The primary outcome of the study is the percentage reduction of SCA after cleaning procedures.

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

preoperative-postoperative macro-photography and photo-based image analysis.

Timeframe: At the time of final access cavity cleaning, immediately following root canal obturation
