【発明の詳細な説明】
（医療上の利用分野）
歯科疾患のなかでも慢性辺縁性歯周炎（いわゆる歯槽膿
漏）はきわめて罹患率の高い疾患である． しかし現在
までの診断方法は不十分であり，処置前後の成績を比較
するための方法論には限界がある． この造影法を応用

き術者ばかりでなく患者サイドにも説明を容易にするこ
とができる．本方法は歯槽膿漏ばかりでなく今後の歯科
医療一般に大いに貢献するものと考える。[Detailed Description of the Invention] (Medical Application Field) Among dental diseases, chronic marginal periodontitis (so-called alveolar pyorrhea) is a disease with an extremely high morbidity rate. However, current diagnostic methods are inadequate, and there are limitations to the methodology for comparing results before and after treatment. By applying this contrast imaging method, it is possible to visually and objectively capture the disease image, making it easier to explain the disease not only to the surgeon but also to the patient. We believe that this method will greatly contribute not only to the treatment of alveolar pyorrhea but also to future dental care in general.

が、 次の条件を具備していなければならない。(Conventional method @) Currently, periodontal pocket probes,
Periodontal pockets are measured directly or indirectly using computer image processing of dental X-rays and κ-rays. Of these, periodontal pocket probes and dental X-ray photographs, which are inexpensive and easy to measure, are routinely used by general clinicians, including general practitioners.
However, periodontal pocket probes can only measure the depth at one measurement point in the cul-de-sac, there is a risk of perforation at the bottom of the cul-de-sac, it is difficult to measure the root isthmus, and it is difficult to adjust the measurement pressure.
It has various drawbacks such as the grasping position of the cul-de-sac,
The reliability of its accuracy is low. Dental xtiJ photographs can mainly distinguish only hard tissues such as alveolar bone, making it difficult to estimate periodontal pockets. In addition, in the case of buccal and old injuries (palatal side), the alveolar bone and tooth root overlap, so there are drawbacks such as the need for skill to measure the position6 (Example) Inject the contrast medium described later into the syringe barrel and blunt the tip. Insert the syringe needle into the cul-de-sac (periodontal pocket) and slowly inject into the target area. The premise is that the tooth in question does not have it.It is also possible to apply it to normal tooth grooves, or to cavities in the body such as extraction sockets, the area around the crown of an impacted tooth, cysts, internal dental disease, and external cavities.
(However, it is necessary to wash the contrast medium thoroughly after imaging.) Various commercially available contrast agents can be used, but the following conditions must be met.
（１）歯牙や骨組織以上のＸ線不透過度を有し造影剤と
組織の鑑別が容易であること。(1) It has an X-ray opacity higher than that of teeth or bone tissue, and it is easy to distinguish between the contrast agent and the tissue.
（２）組織為害性を有しないこと。(2) It must not be harmful to organizations.
（釦洗浄によＶ容易に除去できること。(V can be easily removed by button cleaning.
（４）組織圧により容易に排出されたり、 自然に流れ
出すことのないような適度な粘調性を有すること。(4) Appropriate viscosity so that it is not easily expelled by tissue pressure or flows out naturally.
（５）できれば殺菌消毒剤や抗生剤を含有していること
。(5) If possible, it should contain sterilizing disinfectants and antibiotics.
（６）できれば長期間の保存性を有すること。(6) If possible, it should have long shelf life.
これらの条件をすべて満たすものとして現在著者が使用
しているものは市販の油性造影剤（リビオドール）と硫
酸バリウム（粉末）ならびにアクリノール粉末を調合し
ている。The method currently used by the author that satisfies all of these conditions is a mixture of a commercially available oil-based contrast agent (Libiodol), barium sulfate (powder), and acrinol powder.

This makes it possible to detect tilted teeth, old injuries, or palatal cul-de-sacs (periodontal pockets). *It also became possible to accurately measure the depth of the cul-de-sac at any location using water droplets.
