2. Description of the Related Art In the field of dental restoration, development of a polymerizable composition capable of removing the smear layer or used as an adhesive primer to enhance the adhesive strength of the adhesive has been long awaited. That is, in dental restoration, when the dental caries part is removed and a cavity is formed, a smear layer composed of microorganisms and cutting debris is formed on the exposed part of the dentin surface. This smear layer has been thought to be harmful because it serves as a hotbed for microorganisms and interferes with the adhesion of restorative agents to cause microleakage (Brenstrom, M. and Nyborg, H., J. Pro.
sthet. Dent, Volume 30, Pages 303-310, 1973.

<Test Example> The test method will be described in detail below. Adhesive shear strength test Human molars stored in a 1% chloramine solution at room temperature were used as test teeth. The molars were embedded in a cylindrical plastic mold having a height of 30 mm and a diameter of 15 mm using a quick-curing acrylic resin ("Sample-Quick" manufactured by Buehler). The crown of the tooth was removed using a low speed saw ("Ismet" manufactured by Buehler). The occlusal portion of the exposed dentin surface was polished on a polishing machine with 800-grain silicon carbide paper ("DAP-V" manufactured by Struze Co.). The embedded teeth were washed with fluoride-free water and then dried with oil-free compressed air. The adhesion site was localized by using a waterproof waterproof sticker having an opening with a diameter of 3 mm in the center. A cylindrical plastic tube with a diameter of 5 mm and a height of 2 to 3 mm was placed in the opening and fixed with dental wax. The dentin pretreatment agent was applied to the dentin surface, treated for 60 seconds, and then completely dried using compressed air. The adhesion primer and adhesive were then applied according to the prior art. The uncured adhesive was uniformly applied onto the dentin after the primer treatment using a brush so that air bubbles would not be entrapped. The adhesive was cured for 20 seconds using a visible light source (Optilux 400 "manufactured by Demetron Research).

Light cured for seconds. Then, after being stored in distilled water at 37 ° C. for 24 hours, the test tooth was horizontally attached to a holder for measuring adhesive shear strength and placed so as to be parallel to the vertical axis of the composite resin. Adhesive strength is measured mechanically (Instron Model 101 manufactured by Instron

Micro Leakage Test As a test tooth, a human molar tooth stored under the same conditions as in the above-mentioned adhesive shear strength test was used, and a healthy tooth having no history of decalcification, caries or treatment was selected. Sixty V-shaped cavities having a cheek side and a tongue side were formed. Cavity is about 1.5 mm deep and 3.5 wide
mm, and a height of about 2.0 mm, formed on the cement-ivory boundary. The cavity was formed by cooling with a water spray coolant while using the ultra-high speed handpiece No. 56 tungsten carbide grinding bar (manufactured by Shofu Co., Ltd.) was used. The edge of the cavity surface is 90 ° with a hand tool
Angled. A primer was applied to the surface of the cavity that had been etched for 60 seconds with an enamel etching agent (“Scotch gel” manufactured by 3M Co.) and dried completely with compressed air. Then apply uncured adhesive to the cavity surface,
After photocuring for 2 seconds, "Silux" manufactured by 3M Co., Ltd. as a composite resin was filled on the surface and photocured for 40 seconds. After being soaked in distilled water at 37 ° C. for 24 hours, all the restored test teeth were finish-dried in a finishing disc as in the actual dental treatment.

In order to prevent the dye from penetrating into areas other than the exposed margins, the area of the margin of 2 mm on the restoration part of the test tooth was sealed with nail nail polish. The root apex of the tooth was blocked with a photo-curing composite resin. Each test tooth was placed in a nylon mesh bag and held at 5 ° C for 30 seconds, then at 55 ° C for 30 seconds, and at 5 ° C for 30 seconds.
Repeated 00 times. After completion of the temperature cycle, the test tooth was immersed in a 50% aqueous solution of silver nitrate in the dark for 2 hours, and then thoroughly washed with distilled water. The test tooth was put in a developing solution and irradiated with a fluorescent lamp for 4 hours to expose a permeation pattern of minute leakage, and then thoroughly washed. Thereafter, the test tooth was longitudinally cut in the cheek-lingual direction using an Isomet saw.

In the case of a 10% H 3 PO 4 aqueous solution, it is considered that the adhesive force is likely to be lowered because the collagen at the application site is probably denatured.

As is clear from Tables 4 and 5, the adhesive primer of the present invention can be applied to the occlusal surface side in the cavity of the cement-ivory boundary formed during the treatment of root caries, for example.
It can be seen that the effect of preventing minute leakage is excellent on both the apical side. In this case, the apex side has a higher degree of penetration of microleakage than the occlusal surface side. This is because the dentin tubules on the occlusal surface side are running toward the outside of the tooth surface.
Especially in the in vitro test, it is considered that the part is dried quickly. The more thoroughly this drying is performed, the better the sealability of the rim of the cavity is obtained from the apical side having the thin tube running toward the pulp. From the above, it can be seen that the adhesive primer of the present invention is superior to the comparative agent in preventing microleakage even when repairing root caries.

The present invention is configured as described above, and the effects summarized below can be obtained. (1) By applying the pretreatment agent of the present invention to dentin having a cavity, the smear layer adhered to the dentin surface can be sufficiently removed. (2) As a result of the smear layer being removed, restorations such as composite resin can be firmly adhered to the cavity dentin surface. (3) Further, by using the adhesive primer of the present invention, the restoration and the cavity surface do not come into close contact with each other to form a gap, so that a good marginal sealing property can be obtained, and bacteria etc. can invade through the gap. Since there is no residual bacteria and the like, secondary caries can be prevented. (4) Since the dentin tubule is plugged, foreign matter can be prevented from entering the tubule and irritation to the pulp during and after treatment can be reduced.
