简要总结
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.
详细描述
Plaque is a contributing factor for the development of dental diseases including tooth decay and gum disease. Thus, an excellent standard of oral hygiene is required to ensure all plaque is removed from the teeth to reduce the risk of developing these diseases.
Plaque accumulation starts and is greatest at plaque stagnation sites, which tend to be at the gum margins. In orthodontic treatment, the brackets and archwires are significant plaque stagnation sites.Conventional tooth brushing is also more difficult compounding the increased plaque accumulation and retention.
It is very important that patients learn to recognize the presence of plaque to ensure optimal levels of oral hygiene are achieved. Frequently patients have difficulty localizing the deposits to enable optimal levels of oral hygiene.
Demineralisation occurs due to bacterial fermentation of dietary sugars, which produces acids. This leads to white marks developing on the tooth surfaces, which is the first stage of dental caries. The risk of demineralisation is increased during orthodontic treatment, as there tends to be greater plaque accumulation. Previous studies have reported prevalence rates of demineralisation during orthodontic treatment to be as high as 96%. The most visible front surfaces of the teeth are often the most severely affected which can have a detrimental impact on their appearance.
Early demineralisation can be reversible if plaque control is improved, however progresses cavities may develop which require restoration. The main form of management of demineralisation is prevention. This is mainly by having an excellent level of oral hygiene and having a diet with a limited number of sugar intakes.

结局指标
主要结局
To find difference in plaque accumulation (ΔR30)between the White light group and QLF groups.
时间窗: 6 Months
The difference in plaque accumulation (ΔR30) between the White light group and QLF groups from visit 1 to visit 3 will be measured. QLFD camera will take QLF(blue light) and WL (white light) photographs. Either white light image or QLF image (based on which group patient is randomized to) will be used to provide visual feedback on plaque accumulation present and focused tooth brushing advice will be provided at three appointments.
次要结局
- To find difference in demineralisation (ΔF) between the White light group and QLF groups from visit 1 to visit 3.(6 Months)
