摘要： An object of the present invention is to provide a dental composition having excellent adhesive effect and simultaneously not causing microleakage.A dental composition of a first embodiment of the present invention includes (A) an acidic-group containing polymerizable monomer, (B) a polymerizable monomer, (C) a filler comprising poly(meth)acrylate particles, (D) a calcium-containing material including tetracalcium phosphate (TTCP) and dicalcium phosphate (DCP), and (E) a polymerization initiator. The component (A) is contained at 16-70 parts by weight based on a total of 100 parts by weight of (A)+(B). The component (B) is contained at 84-30 parts by weight based on a total of 100 parts by weight of (A)+(B). The component (C) is contained at 0.2-297 parts by weight relative to a total of 100 parts by weight of (A)+(B). The component (D) is contained at 0.2-297 parts by weight relative to a total of 100 parts by weight of (A)+(B).

摘要： Provided is a cutting bar for dental use that can cut both dentin and enamel with a single bar unanesthetically and efficiently without causing any pain or unpleasant sensation in a patient, in particular, a cutting bar for dental use that can fundamentally solve the problem in that a cutting blade of a cutting bar rotating at low speed comes into contact with hard enamel present in a surface layer of a tooth during cutting of carious dentin to cause unpleasant sensation in a patient. A cutting bar for dental use includes a head in which a cutting blade is formed; a neck leading to the head; and a handle joined to the neck through an intermediation of a joint portion, wherein diamond abrasive grains are electrodeposited in a predetermined range extending from a substantially maximum diameter portion of the head to the neck.
摘要翻译：提供了一种用于牙科用途的切割条，其可以在非麻醉和有效的情况下用单个条切割牙质和牙釉质，而不会在患者，特别是用于牙科用途的切割杆中产生任何疼痛或不愉快的感觉，这可以从根本上解决问题在切割龋齿牙本质期间，以低速旋转的切割杆的切割刀片与存在于牙齿表面层中的硬质牙釉质接触，从而在患者体内引起不愉快的感觉。用于牙科用途的切割杆包括其中形成有切割刀片的头部; 通向头部的颈部; 以及通过关节部分连接到颈部的手柄，其中将金刚石磨粒电沉积在从头部的基本上最大直径部分延伸到颈部的预定范围内。
