The Use of Quantitative Light Induced Fluorescence Digital as an Oral Hygiene Evaluation Tool in Orthodontics
United Kingdom60 participantsStarted 2015-12-01
Plain-language summary
During orthodontic treatment bacterial plaque readily accumulates on the teeth. This is because food easily accumulates around the braces and it is more difficult to clean when the braces are in place. The plaque accumulation can lead to demineralisation (white spots) developing on the teeth. This is the start of decay and can lead to permanent marks and fillings being required.Prior to the start of orthodontic treatment adequate oral hygiene is necessary.
During orthodontic treatment, it is important that patients have an excellent level of oral hygiene to prevent plaque accumulating and demineralisation occurring. However, adequate tooth brushing can be difficult to perform as the bacterial plaque is not easily visible. Thus patients may not be able to see which areas need better tooth brushing.
QLFD(Quantitative Light Induced Fluorescence Digital) is a noninvasive method that uses fluorescent light to illuminate the oral bacteria in plaque that are responsible for demineralisation. The purpose of this study is to use the QLFD camera to assess its ability to measure plaque accumulation and demineralisation before the start of orthodontic treatment. The study will also assess the QLFD camera as a tool to improve oral hygiene.

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.
