METHOD FOR TREATING, SEALING AND FILLING DENTAL ROOT CANALS Russian patent published in 2004 - IPC

FIELD: medicine. SUBSTANCE: method involves carrying out mechanical treatment of dental root canal for preparing it to filling. Dental root canal dentin is etched with 15-60% acid solution. The canal is washed and dried with air jet. Then, adhesive system primer is used for filling dental canals in dentine and hybrid layer is produced from collagen fibers and primer allover dentin surface in dental root canal. Apical tooth opening is sealed with bonding material. Dental root canal is filled with bonding material composed of Ca and P to increase Ca content by 6-14% and P content by 3-8% in superficial dental root canal dentin layer. The apical tooth opening is sealed with bonding material distinguished by lesser viscous consistency with respect to one used for filling the rest of dental root canal space. The bonding material is subjected to hardening sealing in this way the apical dental opening. The dental root canal is filled. Another embodiment involves carrying out mechanical treatment of dental root canal for preparing it to filling. Then, adhesive system primer is used for filling dental canals allover dentin surface in dental root canal. Apical tooth opening is sealed with bonding material. The apical tooth opening is sealed with bonding material distinguished by greater viscous consistency with respect to one used for filling the rest of dental root canal space. Dental root canal is filled with bonding material composed of Ca and P to increase Ca content by 6-14% and P content by 3-8% in superficial dental root canal dentin layer. The bonding material is subjected to hardening, sealing in this way the apical dental opening. The dental root canal is filled. One more embodiment involves carrying out mechanical treatment of dental root canal for preparing it to filling. Dental root canal dentin is etched with 15-60% acid solution. The canal is washed and dried with air jet. Adhesive system primer is used for filling dental canals in dentine and hybrid layer is produced from collagen fibers and primer allover dentin surface in dental root canal. Apical tooth opening is sealed with bonding material. The apical tooth opening is sealed with bonding material distinguished by greater viscous consistency with respect to one used for covering the rest surface of the hybrid layer of dental root canal treated with primer. Dental root canal is filled with bonding material composed of Ca and P to increase Ca content by 6-14% and P content by 3-8% in superficial dental root canal dentin layer. The internal volume of bonding material is filled with other filling material in which Ca content is increased by 6-14% and P content by 3- 8% in superficial dental root canal dentin layer adjacent to the bonding material, preventing from tooth filling seal failure. One more embodiment involves carrying out mechanical treatment of dental root canal for preparing it to filling. Then, adhesive system primer is used for filling dental canals allover dentin surface in dental root canal. Apical tooth opening is sealed with bonding material. The apical tooth opening is sealed with bonding material distinguished by greater viscous consistency with respect to one used for covering the rest surface of the dentin layer of dental root canal treated with primer. Bonding material composed of Ca and P is used for covering the rest surface of the dentin layer of dental root canal treated with primer. Bonding material layer composed of Ca and P covers dentin layer surface of dental root canal treated with primer to increase Ca content by 6-14% and P content by 3-8%. The internal volume of bonding material is filled with other filling material in which Ca content is increased by 6-14% and P content by 3-8% in superficial dental root canal dentin layer adjacent to the bonding material, preventing from tooth filling seal failure. EFFECT: high quality of dental root canal treatment. 8 cl
