Abstract
The treatment of black stains has always been a grey area for the dentists to deal with due to its recurrence. The more effective treatments in current literature are lactoferrin, diode laser, laser Nd:YAG and phototherapy. An attempt was made to remove the stain using low level laser therapy with the similar principle of lethal laser photosensitization and photodynamic therapy without the use of any dye. Our study showed a positive result with the reduction of black stains over a period of 1 year. Hence, the use of LLLT could be considered as one of the adjunct treatment modality for chromogenic bacterial stains.
