Comparative Evaluation of The Efficacy of Diode Laser as an Adjunct to Stannous Fluoride In The Management of Dentinal Hypersensitivity : A Clinical Study

Dentinal hypersensitivity (DH) is among the most common problem encountered after any periodontal therapy [1]. It is defined as short, sharp pain arising from exposed dentin in response to external stimuli, which are typically thermal, evaporative, tactile, osmotic or chemical and which cannot be ascribed to any other form of dental defect or disease, Holland et al. The hyperbolic preponderance of dentin hypersensitivity has hastened the investigation of schemes and agents to insure this phenomenon, and to remineralise dental anatomical structure, such as sodium fluoride, stannous fluoride and argentine containing toothpaste [2,3]. Many federal agents have been applied to treat dentinal hypersensitivity since 1000’s of years. The treatment of dentinal hypersensitivity constitute different kinds of regimens, including dentist applied in-office treatments and patient-applied over-the counter dentifrices [4]. Advancement of laser engineering science and its growing employment in dental medicine has contributed an additional alterative option for the treatment of DH. In several studies, diverse wavelengths of diode lasers have been utilized and have demonstrated the most beneficial effects in numerous clinical protocols, justified in high grade (DH) subject [5]. In various clinical trials authors reported that the combination of lasers with various chemical agents have more clinical outcomes as compared to laser treatment alone [6-8]. Hence the aim of the study was to compare and evaluate the efficacy of topical Stannous fluoride alone and in combination with soft tissue diode laser, commonly used as anti-hypersensitivity agent in the management of DH.
