Dental prophylaxis + aPDT
Study volunteers with black plaque stained teeth will receive standard dental prophylactic cleaning to remove the stain. The prophylaxis will be carried out using an ultrasonic scaler, prophylaxis brush and abrasive paste.
Study volunteers with black plaque stained teeth will receive standard dental prophylactic cleaning, followed by antimicrobial photodynamic therapy (aPDT) to remove the stain. The prophylaxis will be carried out using an ultrasonic scaler, prophylaxis brush and abrasive paste. The aPDT protocol is as follows: Patient will rinse the oral cavity with 20 ml of an aqueous solution of curcumin (photosensitizer; 1.5 g/L) for 30 seconds. Blue light from a Bluephase 20i curing lamp will be applied perpendicularly for 1 min per tooth (30 seconds on the vestibular side and 30 seconds on the palatal side). Remaining photosensitizer will be removed using the prophylaxis brush. The aPDT protocol is repeated following a rest period of 10 days.
