We then examined the state of adhesion when the dentin was sealed with a light-cured composite resin for the treatment of dentin hypersensitivity.","subitem_description_type":"Abstract"},{"subitem_description":"Methods: Human molar teeth were used for this experiment. For the experiment. pieces of coronal dentin were smoothed to a flat surface and their coronal sides were abraded with wet sandpaper until #600. in order to prepare dentin disks of 1 llllll thickness. 'With dentin disks that would be subjected to pressure of 25 mmHg, the same as human intrapulpal pressure, the in vitro model of hypersensitive dentin was prepared. Then adhesives of four types of one-bottle one-step bonding system (BeautiBond Multi (BB) , G-BOND PLUS (GB), Scotchbond™ Universal Adhesive (SU) and CLEARFILR S3BOND ND Quick (TB) ) were applied.\nOn the other hand, the control group was prepared through the same procedure except that the dentin disks of 1 mm thickness were not put on the apparatus. After the adhesive was applietl, they were preserved in water at 37℃ for 24 hours or 6 months and then subjected to the tensile bond strength test, creating four groups: 24h control group, 24h restored dentin group. 6M control group, and 6M restored dentin group (n = 7).\n","subitem_description_type":"Abstract"},{"subitem_description":"Results: Concerning the specimens after 24-hour preservation, TB in the control group and SU and TB in the restored dentin group showed significantly greater bond strength compared with other products. Concerning the specimens after 6-month preservation, in the control group no significant differences were observed among the products, whereas in the restored dentin group SU showed significantly greater bond strength compared with BB. When the 14h control group, the 14h restored dentin group, the 6M control group, and the 6M restored dentin group were compared with each other in each of the products. no significant differences between the 24h control group and the 6 M control group were observed except in TB.","subitem_description_type":"Abstract"},{"subitem_description":"Conclusion: When dentin hypersensitivity is treated with adhesive resins, bonding system including an organophosphate monomer (MDP) are more effective.
