Brief summary

This is a prospective trial designed to evaluate the diagnostic performance of the BlueCheck caries detection system in a cohort of adolescent and adult participants pursuing orthodontic treatment with fixed appliances. The study will recruit participants with at least one active carious lesion, identified by visual inspection. After recruitment, participants will undergo caries diagnosis using both visual inspection and BlueCheck detection (primary objective). Each inspection will be performed by separate assessors. Standardized photographs for orthodontic diagnostic purposes (intraoral frontal and buccal views) will document the dentition before and after BlueCheck detection, and again after BlueCheck removal. Photographic records will subsequently be scored by blinded investigators. Data will be recorded as binary (yes/no) for visual inspection of: 1. initial caries, 2. activity status, and 3. BlueCheck detection. All investigators will have training on caries inspection/assessment evaluations. Lay description: This study will show if caries can be detected by BlueCheck. If so, BlueCheck may be a valuable tool allowing correction of early tooth decay using remineralisation products and obviate the need for more invasive procedures.

Interventions

After the subject's teeth are cleaned as part of routine procedure, a blue dye (BlueCheck) will be painted on the subject's teeth with a dental brush by a oral health professional (1-2 minutes). The subject will then rinse with water (<1 minute), and any residual colour on specific teeth will be noted in data records (2-3 minutes). The blue colour will then be washed off completely with tooth paste (<1 minute). In summary, BlueCheck may be on the teeth up to five minutes. A second professiona

After the subject's teeth are cleaned as part of routine procedure, a blue dye (BlueCheck) will be painted on the subject's teeth with a dental brush by a oral health professional (1-2 minutes). The subject will then rinse with water (<1 minute), and any residual colour on specific teeth will be noted in data records (2-3 minutes). The blue colour will then be washed off completely with tooth paste (<1 minute). In summary, BlueCheck may be on the teeth up to five minutes. A second professional will observe the subject's teeth using standard tactile / visual methods, inspecting for white spot lesions (3-5 minutes) of which there may be more than one. These areas will be recorded on a separate chart (1-2 minutes). This procedure will be undertaken once. This procedure will be delivered in the clinic. All subjects will undergo the same procedure.
