The effect of ND: YAG Laser on dental hypersensitivity

Introduction: Symptom of dentine hypersensitivity attacks 10 % to 15 % of population and causes an uncomfortable pain during contact with any matter. 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 with 58 hypersensitivities teeth were selected for this clinical examination. Ten of the teeth were hypersensitive of the occluzal surface. The sensitive surface was lased with Nd: YAG laser according to the treatment protocol three times after five days. Results: The results of this study showed that Nd: YAG laser has a significant and rapid clinical effect in reducing the dentine hypersensitivity. Only in two cases were needed to be repeated with the laser irradiation three times. At the same time no side effects, were recorded, neither at teeth level, nor at soft tissue level. 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. Key words: Nd:Yag laser, hypersensitive teeth
