الملخص الإنجليزي

Objectives: The purpose of this study was to use a new method for treatment of dentin hypersensitivity and closure of dentinal tubules by combination of Nd:YAg laser and Nano Fluor-hydroxyapatite and compare the occluding effect of dentinal tubules of this type of treatment with other modalities like Cyanoacrylate and sodium fluoride by using scanning electron microscope.

Method: Sixty freshly extracted human premolar teeth had been collected randomly for this study.

The coronal portion of each tooth was removed and the canals were instrumented and obturated with gutta percha.

A 3 mm wide ring of root surface, 2 mm apical to the coronal rim of each specimen was cut by a rotary instrument attached to a special microlathe to expose underlining dentin.

The teeth were divided randomly into six groups : Group 1: Ten teeth were treated with Nano Fluor – hydroxyapatite and Nd:YAG laser ,Group 2: Ten teeth were treated with Nd:YAG laser only, Group 3: Ten teeth were treated with Nano Fluor – hydroxyapatite only, Group 4: Ten teeth were treated with desensitizing cyanoacrylate resin bonding (Tetric N ceram), Group 5.

Ten teeth were treated with 2% sodium fluoride, and Group 6: Ten teeth were not treated with any modality mentioned above (control group).

Scanning electron micrograph with 5000X were taken to show the topography of each group after treatment.

Result and conclusion: The combination of Nano fluor hydroxyapatite and Nd:YAG laser is a promising treatment modality for dentin hypersensitivity and excellent method for closure of exposed dentinal tubules with significant difference when compared with other treatment modalities.
