ND: YAG Laser in the therapy of hypersensitivity teeth clinical evaluation

Introduction: Various methods and materials are used in the treatment of dentin hypersensitivity. Sealing of open dentinal tubules is one of the methods to reach insensibility. Laser as a source of coherent radiation is used to melt layers of dentine surface. Objective: The purpose of this study was to evaluate the clinical effectiveness of Nd: YAG laser in the therapy of hypersensitive teeth. Study design: 43 patients of both sex at the age 26 - 54 were included in the study for clinical evaluation. Hypersensitivity was detected on 58 teeth. In 48 teeth hypersensitivity was located on the tooth’s neck. In 10 teeth the hypersensitivity was located on the ocllussal plain. Nd:YAG laser irradiation was realized in 3 visits depending on the subjective simptomatollogy. We applied laser irradiation on the teeth’s gingival third with the fiber – optic hand piece. Results: The results of this clinical evaluation showed that Nd: YAG laser has a significant and rapid clinical effect in reducing the dentine hypersensitivity. Only in three cases were needed to be repeated with the laser irradiation three times. We have noted 100% success after the first session with the patients that were treated for hypersensitivity on the ocllussal plains. Most of the patients came for a second sesion because they had an appointment and not because they needed therapy. Conclusions: The Nd: YAG laser is a suitable tool for immediate successful reduction of dentinal hypersensitivity and has better patient satisfaction, shorter treatment time, and lower rates of pain. Positive clinical effects recommended this new technology in the clinical practice
