Are the molars and deciduous molars, respectively, and the dental syringe 4 from the opening 3 of the tooth inside the pulp cavity 2 formed by the cavities or the like.
Shows the state of injecting.
【００１３】図において５は浸麻針で、弾性材からなる
封鎖栓６が取り付けられている。この封鎖栓６は、予

た状態で浸麻針５を挿通することにより、浸麻針５に取
り付けられる。In the figure, reference numeral 5 denotes an immersing needle, to which a closing plug 6 made of an elastic material is attached. The sealing plug 6 is attached to the hemp needle 5 in advance or by inserting the hemp needle 5 with the sealing plug 6 applied to the opening 3 of the tooth.
【００１４】上記封鎖栓６はゴム等の弾性材で作成され

用できる。すなわち、弾性材であることにより歯牙の開
口部３に密着させることができ、しかも透明であること
により歯髄の場所を注射の際に確認することができるか
らである。The sealing plug 6 is made of an elastic material such as rubber, and a transparent material such as transparent silicone rubber can be preferably used. That is, since it is an elastic material, it can be brought into close contact with the opening 3 of the tooth, and because it is transparent, the location of the pulp can be confirmed at the time of injection.

端から側面にかけての部位を使って歯牙の開口部３を封
鎖すればよい。It is desirable that the sealing plug 6 is made of an elastic material such as rubber and has a substantially oval shape. That is, FIG.
The opening 3 of the tooth in the case of an anterior tooth as shown in FIG. 2 is generally a small circle, a large oval in the case of a molar as in FIG. 3, and a small oval in the case of a primary molar as shown in FIG. It is oval. Therefore, in the case of the anterior teeth of FIGS. 1 and 2, the opening 3 of the tooth is closed using the oval tip, and in the case of the molar shown in FIG. 3, the opening 3 of the tooth is opened using the oval side. In the case of the deciduous molar shown in FIG. 4, the opening 3 of the tooth may be closed using the part from the tip of the oval to the side surface.
【００１６】上記封鎖栓６で歯牙の開口部３を封鎖する
際は、単に歯科用注射器４で押すだけでは浸潤麻酔液が
漏れ出してしまうため、注射時に封鎖栓６を指で押して
いることが必要である。When the opening 3 of the tooth is sealed with the sealing plug 6, the infiltrating anesthesia solution leaks out when the dental syringe 4 is simply pushed. Therefore, the sealing plug 6 should be pushed with a finger at the time of injection. is necessary.

去にも有効である。According to the above-mentioned closure plug 6, the bursa needle 5 can be held at an appropriate position in the pulp cavity 2, and the bursa needle 5 can be prevented from directly touching the pulp, and the canopy can be removed or removed. As long as it is small in size, the pain of the patient is small and the infusate can be easily infiltrated under pressure. Of course, it is also effective for removing residual pulp teeth.

切の場合にも、有効に対処することができる。Further, as a method for deactivating the pulp, there are paraform paste, arsenous paste paste and the like, and reliable pulp extraction can be efficiently carried out if only the minimum amount of pulp can be exposed. Further, it is possible to effectively deal with the case of raw cutting as shown in FIG.

タイムの短縮が図れるので便利である。Further, it is possible to prevent the infiltrating anesthetic liquid from leaking from the inside of the pulp cavity to the outside of the tooth, to infiltrate the infiltrating anesthetic liquid under pressure without releasing the infiltrating pressure, and to efficiently act the infiltrating anesthetic liquid on the dental pulp. This is convenient for the clinician because the chair time of the patient can be shortened.
