Comparison of LASER Therapy and Desensitizing Agents in Dentinal Hypersensitivity

A glutaraldehyde-based desensitizing agent applied to the cervical area of affected teeth using a micro-brush, left undisturbed for 30 seconds, and air-dried. Both interventions aim to reduce pain associated with dentinal hypersensitivity by either occluding dentinal tubules or reducing nerve excitability

Low-level laser therapy (LLLT) using a diode laser set to a low power level (e.g., 100 mW, continuous wave mode). Each affected tooth will be treated for three minutes, targeting apical, cervical, and middle points
