Durability of Adhesion between 4-META/MMA-TBB Resin and Cementum

Abstract

4-META/MMA-TBB resin has shown good biocompatibility and remarkable adhesion to dentin. It seems to be suitable for use in periodontal tissues for retrograde root sealing and treatment of vertically fractured roots. For an adhesive resin to be useful clinically, it must bond not only to the dentin but also to the cementum. The purpose of this study was to evaluate the long-term adhesion durability of 4-META/MMA-TBB resin to cementum kept in water at 37•Ž. Bovine root cementum and dentin surfaces were treated with 10-3 solution before 4-META/MMA-TBB resin was applied on treated surfaces. The micro-tensile bond strength (ƒÊTBS) decreased during the first two months; dye leakage value increased during the first four months and stabilized thereafter. No significant differences in adhesion durability were recognized between the dentin and cementum.

“…Therefore, 4-META/MMA-TBB resin might show high-level polymerization under wet conditions 37) , high sealing ability, little cytotoxicity and high biocompatibility after complete curing. Our previous studies using dye leakage tests suggested that the leakage values of dentin and cementum increased until the third month and then remained fairly constant until the sixth month 19) , and sealing durability that prevents coronal leakage seemed to be maintained for 1 year 20) . This suggests that root-end sealing using 4-META/MMA-TBB resin might have a good prognosis clinically.…”

“…In our previous studies, 4-META/MMA-TBB resin showed a number of advantages, such as high adhesiveness to dentin and cementum 19) . According to Tanaka et al 20) , dye leakage of root-ends sealed without cavity preparation using 4-META/MMA-TBB resin was significantly less than that of root-end fillings using amalgam and reinforced zinc oxide eugenol cement.…”

Effect of the dental adhesive, 4‐META/MMA‐TBB resin, on adhesion and keratinization of regenerating oral epithelium

“…The 4-META/MMA-TBB [4-(2-methacryloxyethyl)trimellitic anhydride/ methyl methacrylate-tributylborane] resin is widely employed as a dental adhesive. Numerous studies have reported its highly adhesive properties with enamel (1), dentin (1), cementum (2,3) and bone (4,5), and moderate biocompatibility with dentin-pulp complex (6,7) and periodontal tissue (8). Based on the results of those studies, it has also been applied in the dressing of gingival wound surfaces following flap surgery and intentional autotransplantation of teeth (9).…”

“…C&B ® ), is widely utilized as a dental adhesive in Japan. Previous studies have reported its excellent adhesive properties with tooth hard tissues, including enamel [11], dentin [12] and cementum [13], and a moderate biocompatibility with dental pulp [14] and periodontal tissue [15,16]. Furthermore, several studies in recent years have reported its bond strength to bone [17,18].…”
