Abstract
Introduction: The demand for tooth whitening has increased dramatically with the resulting development of new tooth whitening products and procedures. As it is a common scenario that the dentists come across paan stained teeth very regularly in dental practice, the need for this study is to compare if laser bleaching or three day home bleaching is effective for paan stained and give better treatment options for patients.
 Aim: To compare the effect of laser bleaching on paan stained tooth with home bleaching tooth using digital spectrophotometer
 Methodology: 20 extracted teeth were preserved in a solution of normal saline with 1% thymol crystals. The teeth were immersed in staining solution containing paan extracts for a period of two week. The specimens were evaluated for pre shades using VitaEasyShade. The stained specimens for paan respectively were divided randomly into 2 groups one for laser bleaching and other for home bleaching. POLA OFFICE + was applied on tooth and activated using the diode laser as per the manufacturer’s instructions for group 1. The bleaching was carried out with Philips Zoom Nitewhite for group 2. The second colour measurement of the specimens was made using VitaEasyShade.
 Conclusion: The results showed that laser bleaching was effective when compared to three day home bleach in paan stained teeth using digital spectrophotometer.

Summary
Patients can be dissatisfied with their tooth colour and request tooth whitening for a whiter smile. Demand for tooth whitening has increased dramatically with the resulting development of new tooth whitening products and procedures. It is of paramount importance for the practitioners to recognise and know the cause of discoloration to arrive at a correct diagnosis and successful treatment. No studies have been performed to check the effect of bleaching on paan stained teeth. The dentists come across paan stained teeth very frequently in their practice, the aim of this study was to compare the effectiveness of laser bleaching with home bleaching of paan stained teeth and give better treatment options for patients. The specimens were rinsed with tap water for ten (10) seconds and air dried
