Plain-language summary
Objectives: The aim of this study is to investigate the effect of photobiomodulation therapies on root resorption compared with the placebo group. Materials and Methods: 30 patients, who were admitted to the …………. University Faculty of Dentistry Orthodontics Department for treatment, with an indication of upper right 1st premolar tooth extraction was included. Before the individuals' orthodontic treatment, 0.022 slot MBT brackets and tubes were placed on the maxillary 1st premolar and molar. A 150g buccal tipping force was applied to the 1st premolar. Individuals were then randomly divided into 3 groups. For the first group; laser application was performed with a 810 nm GaAlAs laser device at 0,3,7,14,21 and 28 days to 8 J/cm2. Second group; an LED application according to the manufacturer's instructions with a 850 nm wavelength and 20 mW/cm2 output power for 10 minutes per day during the experiment. Third group; a placebo therapy was completed whereby a laser device that did not make active pulses was used. At the end of four weeks, the amount of root surface resorption was compared using micro-CT imaging after the extraction of the teeth.

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