Embodiment 1-11

[0177] Tributylboron (oxygen added: 0.8 mol%) and filler shown in Table 1 were mixed in the same manner as above to prepare a polymerization initiator paste composition.

[0178]The polymerization initiator paste composition was charged into a commercially available 2.5 ml plastic syringe, and discharged from a discharge nozzle (inner diameter: 0.9 mm or 1.8 mm, length: 10 mm), and then the polymerization initiator paste was inspected. The discharge properties of the compound.

[0179] In Table 1, AA indicates that the discharge property of the composition is good; BB indicates that the discharge property of the composition is poor; CC indicates that the composition does not discharge.

[0180] Next, the adhesive strength of the polymerization initiator paste composition and dentin was measured according to the method described below.

[0181] (1) Under pouring, the labial surface of the bovine anterior teeth was ground to expose the dentin, and the dentin was polished with N...

Abstract

The present invention is a polymerization initiator paste composition which comprises (A) an organoboron compound which is liquid at 25 DEG C and (B) particles having an average particle diameter of 0.001 to 50 mu m and inert to the organoboron compound (A), in an amount of 4 to 400 parts by weight based on 100 parts by weight of the organoboron compound (A), and has a consistency, as measured at 25 DEG C under a load of 300 g in accordance with a method defined in ISO4823, of 15 to 100 mm. This composition constitutes a dental kit or the like together with a polymerizable monomer separately packaged. According to the present invention, an organoboron compound can be used safely, and because the composition is a paste, it is very easily utilized.

Description

technical field [0001] The present invention relates to a polymerization initiator paste composition, which can be used as a polymerization initiator for dental or surgical adhesives. The present invention also relates to a dental or surgical adhesive using the paste composition. agent and the adhesive component. More specifically, the present invention relates to a polymerization initiator paste composition which is excellent in storage stability, handling and economical efficiency, and to a composition which is excellent in adhesiveness to dentin and hard tissues. Dental or surgical adhesives and dental or surgical adhesive components. Background technique [0002] In recent years, organoboron compounds, specifically tributylboron (TBB) or TBB partial oxides, have been used as polymerization initiators for dental adhesives because of their excellent adhesiveness to dentin. [0003] However, TBB is a liquid with low viscosity at working temperature (room temperature), and...
