Effect of Post Preparation Dentinal Hypersensitivity Treatment by Fractional CO2 (10600 nm) Laser on Shear Bond Strength of Resin Cement to Dentin: In Vitro Study
Author(s): Rusal Mohammed Mubarak* and Basima Mohammed Ali Hussein
Background: After crown preparation of vital tooth, the tooth would be sensitive due to increased number of open dentinal tubules. Dentinal hypersensitivity described as severe and sharp pain evoked by thermal, tactile, osmotic and chemical stimuli. Laser was considered as an effective treatment of dentinal hypersensitivity of exposed root dentin. Aim of this study: To evaluate the desensitization effect of fractional CO2 laser (1 W, 2.5 ms, 2.5 mJ) and (1 W, 2.5 ms, 2.5 mJ) on shear bond strength of dentin to resin cement. Materials and methods: Sixty three sound maxillary premolars (n=21) were collected and prepared occlusally to expose dentin, these teeth were divided into three groups. Group A: Dentin surface was irradiated with fractional CO2 (1 W, 2.5 mJ, 2.5 ms), group B: Dentin surface was irradi.. Read More»
