Description

【0001】
【発明の属する技術分野】
本発明は、抗菌成分を含有させた模型材、印象材等の歯科用組成物に関するものである。
【0002】
【従来の技術】
歯科分野における組成物としては、用途別には裏装材,合着材,模型材,仮封材,根管充填材,印象材等があり、それぞれの歯科用組成物はその用途に応じて各種の原料から構成されている。
【0003】
歯科用組成物を主成分を構成する原料から見ると、明確な区別はできないが、無機成分を主成分とするもの(歯科用セメント,硬質レジン歯,模型材,一部のコンポジットレジン,一部の仮封材や根管充填材等),プラスチックを主成分とするもの(床用レジン,常温重合レジン,裏装用軟質レジン,一部の仮封材等),天然樹脂やその他の樹脂を主成分とするもの(アルジネート印象材,寒天印象材,シリコーンラバー印象材,ポリサルファイドラバー印象材,根管充填材等)がある。
【0004】
これらの歯科用組成物は口腔内で使用するため従来から抗菌対策とその改良が行われてきた。特に印象材や床用レジン等のように微生物が付着しやすい条件で使用する歯科用組成物や、天然樹脂やその他の樹脂を主成分とするもののように微生物が繁殖しやすい原料を用いた歯科用組成物の場合には積極的に抗菌対策を施すことが望ましい。
【0005】
従来から歯科用組成物に抗菌対策として用いられている抗菌剤としては、グリコン酸クロルヘキシジン、塩酸クロルヘキシジン、N−アシルアミン酸誘導体、有機アルミニウム化合物、有機珪酸化合物、有機ジルコニウム化合物、タンニン、ソルビン酸、安息香酸ナトリウム等がある。これらの物質は有機物であるために耐久性に欠ける欠点がある。また後述する無機の抗菌剤と同様に、抗菌の効果を示すためには歯科用組成物から抗菌剤を経時的に流出させる必要があるので人体に対する安全性にも問題があった。
【0006】
有機抗菌剤の耐久性の欠点を解消するために、銀、銅、亜鉛等の金属イオンをゼオライト、活性アルミナ、シリカ等に含有させた無機の抗菌剤を使用した歯科材料組成物が開発されている(例えば、特許文献1〜5参照。)。しかし、銀、銅、亜鉛等の金属イオンをゼオライト、活性アルミナ、シリカ等に含有させた無機の抗菌剤を使用した歯科材料組成物も抗菌効果を示すためには無機物質に含有される金属イオンを経時的に流出させる必要がある。金属イオンの流出は樹脂製の義歯や床を変色させるだけでなく、歯科用組成物が口腔内に適用するものであることを考えるとやはり安全性に問題があった。
【0007】
他にも、植物から有機溶剤により抽出した抗菌成分を抗菌剤として用いた歯科用組成物や(例えば、特許文献6参照。)、抗菌性の酵素等を用いた歯科用組成物等も提案されている(例えば、特許文献7参照。)。しかし、これらの歯科用組成物に用いられている抗菌剤は、前述の抗菌剤に比べると安全であるという利点はあるものの、反面、抗菌の効果が小さいという本質的な問題点がある。また、植物から有機溶剤により抽出した抗菌成分を抗菌剤として用いた歯科用組成物ではその植物特有の看過できないにおい・味・着色がある欠点があり、抗菌性酵素を用いた歯科用組成物は比較的高価であるという欠点があった。このことは、特に低価格であることが求められる印象材等の歯科用組成物に添加する抗菌剤としては適当ではない。

【発明が解決しようとする課題】
そこで本発明は、優れた抗菌性を持ちながら前記従来の抗菌性歯科用組成物の欠点である経時的な抗菌剤の流出の虞が無い抗菌性歯科用組成物を提供することを課題とする。
【0010】
【課題を解決するための手段】
本発明者等は前記課題を解決すべく鋭意研究を重ねた結果、ヨウ素と陰イオン交換樹脂との化合物である抗菌剤はイオン交換樹脂内部に確実に抗菌成分であるヨウ素を封じ込めておくことが可能であり、バクテリアやウィルス等が陰イオン交換樹脂に近づいた時にだけ抗菌成分であるヨウ素を放出するという特徴に着目して本発明を完成させた。
【0011】
即ち本発明は、ヨウ素と陰イオン交換樹脂との化合物を含有させた抗菌性歯科用組成物である。
【0012】
本発明に係る抗菌性歯科用組成物としては、その抗菌性を付与する対象として具体的な歯科用組成物を挙げると、例えば無機成分を主成分とするもの(歯科用セメント,硬質レジン歯,模型材,一部のコンポジットレジン,一部の仮封材や根管充填材等),プラスチックを主成分とするもの(床用レジン,常温重合レジン,裏装用軟質レジン,一部の仮封材等),天然樹脂やその他の樹脂を主成分とするもの(アルジネート印象材,寒天印象材,シリコーンラバー印象材,ポリサルファイドラバー印象材,根管充填材等)を挙げることができる。これらの中でも用途的には模型材,仮封材、根管充填材,印象材がヨウ素と陰イオン交換樹脂との化合物による着色の影響を受けない点で適切であり、更に仮封材、根管充填材,印象材が微生物が付着しやすい条件で使用する点からより適切である。また、材料的にはアルジネート印象材,寒天印象材,シリコーンラバー印象材,ポリサルファイドラバー印象材,トランスポリイソプレン等を主成分とする根管充填材等が微生物が繁殖しやすい原料を用いている点から適切である。
【0013】
前術の全ての条件を満たすことから印象材、特にアルジネート印象材が最も重要である。アルジネート印象材の主な組成は、アルギン酸塩、せっこう(ケイ酸鉛を用いることもある)、ケイソウ土(他の充填材を用いることもある)であり、アルギン酸塩としてはアルギン酸のナトリウム塩、カリウム塩、マグネシウム塩、アンモニウム塩、トリエアノールアミン塩等が用いられる。そのほか、第三リン酸ナトリウム、炭酸ナトリウム等が硬化時間調節剤として用いられ、また滑沢剤(フッ化亜鉛等)、着色剤、香料等を適宜配合することができる。アルジネート印象材の形態としては、これらの成分を粉末にしたものと水とを使用時に練和する粉液タイプの他に、アルギン酸塩及び水を主成分とする基材ペーストと、硫酸カルシウム及び有機溶剤を主成分とする硬化材ペーストとからなるペーストタイプがある。
【0014】
ヨウ素と陰イオン交換樹脂との化合物は、陰イオン交換樹脂に三価ヨウ素を結合させた小球状や微粒子状のもので、例えば特公昭39−3102号公報,特公昭39−11454号公報,特公昭39−11455号公報,特公昭39−11456号公報の各方法に於いて製造されるヨウ素と陰イオン交換樹脂との化合物を用いることができる。また、製品としては「商品名:TRIOSYN (登録商標),HIDORO・BIOTECH 社製」や「商品名:アイオマックサンド(登録商標),松井産業株式会社製」として提供されている。このヨウ素と陰イオン交換樹脂との化合物である抗菌剤は、核酸や酸性アミノ酸等を含むバクテリアやウィルス、黴等の陰イオン物質が近づくと、樹脂内部に結合されているヨウ素が樹脂から放出されて瞬時に殺菌をするので放出されるヨウ素の量はバクテリアやウィルス等の数に相応する量だけが必要量だけ交換放出されるから、殺菌時に余分なヨウ素を放出したり経時的にヨウ素を人体に流出し続けることがない。
【0015】
本発明に係る抗菌性歯科用組成物に混入するヨウ素と陰イオン交換樹脂との化合物の量は、配合する歯科用組成物中に0.001〜10重量%であることが好ましい。配合量が0.001重量%よりも少なくないと有効な抗菌効果が得られ難く、また、10重量%を超えて配合すると歯科用組成物の持つ本来の各種機能や効果が低下する虞がある。より好ましくは0.01〜5重量%である。このとき、元になる歯科用組成物は粉と水とに分けて保管され使用時に練和するタイプのアルジネート印象材や歯科用セメントであれば水の重量は含まないものとする。
【0016】

次に実施例を用いて本発明を更に説明する。以下「%」とあるのは重量%である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dental composition such as a model material and an impression material containing an antibacterial component.
[0002]
[Prior art]
Compositions in the field of dentistry include lining materials, luting materials, model materials, temporary sealing materials, root canal filling materials, impression materials, etc. for each application. It consists of raw materials.
[0003]
Dental compositions cannot be clearly distinguished from the raw materials that make up the main components, but those that contain inorganic components as the main components (dental cement, hard resin teeth, model materials, some composite resins, some Temporary sealing materials and root canal filling materials), plastic-based materials (floor resin, room temperature polymerization resin, soft resin for lining, some temporary sealing materials, etc.), natural resins and other resins There are components (alginate impression material, agar impression material, silicone rubber impression material, polysulfide rubber impression material, root canal filling material, etc.).
[0004]
Since these dental compositions are used in the oral cavity, antibacterial measures and improvements have been conventionally performed. In particular, dental compositions used under conditions where microorganisms are likely to adhere, such as impression materials and floor resins, and dental materials that use microorganisms, such as natural resins and other resins, whose main components are easy to propagate In the case of a composition for use, it is desirable to actively take antibacterial measures.
[0005]
Antibacterial agents conventionally used as antibacterial measures in dental compositions include chlorhexidine gluconate, chlorhexidine hydrochloride, N-acylamic acid derivatives, organic aluminum compounds, organic silicate compounds, organic zirconium compounds, tannin, sorbic acid, and benzoic acid. Acid sodium and the like. These substances have a drawback that they lack durability because they are organic substances. In addition, similarly to the inorganic antibacterial agent described later, it is necessary to allow the antibacterial agent to flow out of the dental composition with time in order to exhibit the antibacterial effect.
[0006]
To solve the durability shortcomings of organic antibacterial agents, dental material compositions using inorganic antibacterial agents containing silver, copper, zinc and other metal ions in zeolite, activated alumina, silica, etc. have been developed. (For example, refer to Patent Documents 1 to 5). However, a dental material composition using an inorganic antibacterial agent containing a metal ion such as silver, copper, or zinc in zeolite, activated alumina, silica, or the like is also required to exhibit an antibacterial effect. Need to flow out over time. The outflow of metal ions not only discolors dentures and floors made of resin, but also poses a safety problem in view of the fact that the dental composition is applied to the oral cavity.
[0007]
In addition, a dental composition using an antibacterial component extracted from a plant with an organic solvent as an antibacterial agent, and a dental composition using an antibacterial enzyme and the like (for example, see Patent Document 6) have been proposed. (For example, see Patent Document 7). However, although the antibacterial agents used in these dental compositions have the advantage of being safer than the above-mentioned antibacterial agents, they have the essential problem that the antibacterial effect is small. In addition, a dental composition using an antibacterial component extracted from a plant with an organic solvent as an antibacterial agent has a disadvantage that there is an odor, taste, and coloring that cannot be overlooked peculiar to the plant, and a dental composition using an antibacterial enzyme is There was a disadvantage that it was relatively expensive. This is not suitable as an antibacterial agent to be added to a dental composition such as an impression material, which is required to be inexpensive.

[Problems to be solved by the invention]
Therefore, an object of the present invention is to provide an antibacterial dental composition which has excellent antibacterial properties and does not have a risk of the antibacterial agent flowing out over time, which is a drawback of the conventional antibacterial dental composition. .
[0010]
[Means for Solving the Problems]
The present inventors have conducted intensive studies to solve the above problems, and as a result, the antibacterial agent, which is a compound of iodine and an anion exchange resin, is to securely contain iodine, which is an antibacterial component, inside the ion exchange resin. The present invention has been completed by paying attention to the feature that it is possible to release iodine which is an antibacterial component only when bacteria, viruses and the like approach the anion exchange resin.
[0011]
That is, the present invention is an antibacterial dental composition containing a compound of iodine and an anion exchange resin.
[0012]
Examples of the antibacterial dental composition according to the present invention include those having an inorganic component as a main component (dental cement, hard resin tooth, Model materials, some composite resins, some temporary sealing materials, root canal filling materials, etc., plastics as main components (floor resin, room temperature polymerization resin, soft resin for lining, some temporary sealing materials) Etc.), and those containing natural resin or other resin as a main component (alginate impression material, agar impression material, silicone rubber impression material, polysulfide rubber impression material, root canal filling material, etc.). Among these, the model material, the temporary sealing material, the root canal filling material, and the impression material are suitable in that they are not affected by the coloring by the compound of iodine and the anion exchange resin. It is more appropriate because the tube filler and impression material are used under conditions where microorganisms easily adhere. In addition, alginate impression material, agar impression material, silicone rubber impression material, polysulfide rubber impression material, root canal filling material mainly composed of trans polyisoprene, etc. are made of raw materials in which microorganisms easily propagate. Suitable from.
[0013]
The impression material, especially the alginate impression material, is the most important because it satisfies all the conditions of the previous operation. The main composition of the alginate impression material is alginate, gypsum (sometimes using lead silicate), diatomaceous earth (sometimes using other fillers), and as the alginate, the sodium salt of alginic acid, Potassium salts, magnesium salts, ammonium salts, triethanolamine salts and the like are used. In addition, sodium triphosphate, sodium carbonate, and the like are used as a curing time regulator, and a lubricant (such as zinc fluoride), a coloring agent, a fragrance, and the like can be appropriately compounded. As the form of the alginate impression material, besides a powder-liquid type in which these components are powdered and water are kneaded when used, a base paste containing alginate and water as main components, calcium sulfate and organic There is a paste type composed of a hardener paste containing a solvent as a main component.
[0014]
The compound of iodine and an anion exchange resin is in the form of small spheres or fine particles in which trivalent iodine is bonded to an anion exchange resin. For example, JP-B-39-3102, JP-B-39-11454, Compounds of iodine and an anion exchange resin produced by the methods disclosed in JP-B-39-11455 and JP-B-39-11456 can be used. In addition, products are provided as "trade name: TRIOSYN (registered trademark), manufactured by HIDORO BIOTECH" or "trade name: Iomax Sand (registered trademark), manufactured by Matsui Sangyo Co., Ltd." This antibacterial agent, which is a compound of iodine and an anion exchange resin, releases iodine bound inside the resin from the resin when anionic substances such as bacteria, viruses, and molds containing nucleic acids and acidic amino acids approach. As it is sterilized instantaneously, the amount of iodine released is exchanged and released by the required amount only for the number of bacteria, viruses, etc., so extra iodine is released at the time of sterilization or iodine is removed over time by the human body. Never spill out.
[0015]
The amount of the compound of iodine and an anion exchange resin mixed in the antibacterial dental composition according to the present invention is preferably 0.001 to 10% by weight in the dental composition to be compounded. If the amount is less than 0.001% by weight, it is difficult to obtain an effective antibacterial effect. If the amount exceeds 10% by weight, the original functions and effects of the dental composition may be reduced. . More preferably, it is 0.01 to 5% by weight. At this time, the weight of water is not included in the case of an alginate impression material or a dental cement of a type in which the original dental composition is stored separately in powder and water and kneaded at the time of use.
[0016]

<Comparative Example 1 and Comparative Example 2>
An alginate impression material in which the compound of iodine and an anion exchange resin was replaced with sodium alginate from Example 4 was used as Comparative Example 1, and an alginate impression material in which the compound of iodine and an anion exchange resin was replaced with chlorhexidine chloride in Example 4. Was set as Comparative Example 2.
[0023]
Each of the dental compositions of Examples 1 to 5 and Comparative Examples 1 and 2 was solidified into a disk having a diameter of 12 mm and a thickness of 8 mm according to a conventional method. As a method of solidification, the root canal filling material is softened to 130 ° C., and the paste type alginate impression material is mixed in an equal amount by weight of the base material and the hardening material paste and fitted into a resin mold, and the powder type alginate impression material is used. The materials were mixed and kneaded with 14% by weight of powder and 40% by weight of water, and fitted into a resin mold. After the composite resin was fitted into a resin mold, both sides were irradiated with light for 30 seconds using a light irradiator (trade name: GC Labolite VL-II, GC Corporation) to polymerize and cure.
[0024]
<Antibacterial test>
One of the discs of the above Examples and Comparative Examples was immersed in 50 ml of Sabouraud's medium using Candida bacteria as the bacterial species, and the number of viable cells after culturing at 37 ° C. for 24 hours was measured. Using Comparative Example 1 as a control, the antibacterial activity was determined based on the viable cell count as compared with the control. As a result, it was confirmed that all of the antibacterial dental compositions of Examples 1 to 5 and Comparative Example 2 had a significantly lower viable cell count than the control.
[0025]
<Skin temporary irritation>
The above-mentioned various dental compositions in a disc shape were closed and patched on the right side of the back of a male Kbz: NZW rabbit for 4 hours, and observed up to 72 hours after the patch was removed. As a result, none of the antibacterial dental compositions of Examples 1 to 5 showed any stimulus reaction up to 72 hours after the patch was removed, but Comparative Example 2 slightly discolored red after the patch was removed and caused skin irritation. Was observed.
[0026]
<Spill test>
One of the disks of the above Examples and Comparative Examples was immersed in 100 ml of distilled water at 40 ° C., at an amplitude of 50 mm and at a frequency of 60 times / minute for 60 days. As a result, all the antibacterial dental compositions of Examples 1 to 5 had significantly less viable bacteria count than Comparative Example 1 as a control, that is, the same result as the antibacterial test without immersion in distilled water. Was confirmed. On the other hand, in Comparative Example 2, although the number of viable cells was smaller than that of the control, the number of viable cells was about three times that of the various examples.
【The invention's effect】
As is clear from the above, the antibacterial dental composition according to the present invention has excellent antibacterial properties, and the compound of iodine and the anion exchange resin contained therein is an anionic substance such as bacteria, viruses, and molds. Only when approaching, iodine is released from the resin and sterilized, so the amount of iodine released is exchanged and released by the necessary amount corresponding to the number of bacteria, viruses, etc. It was confirmed that the composition was an excellent antibacterial dental composition in which iodine did not continuously flow out.
