- Periodontal disease is considered to be an infectious disease caused by colonization of pathogenic bacteria in the oral cavity, and it is important to eliminate infected pathogenic bacteria for the prevention and improvement of periodontal disease. For this reason, various bactericides and antibiotics are used, but pathogenic bacteria that cause periodontal disease form biofilms and are known to be resistant to bactericides and antibiotics. Therefore, isopropylmethylphenol, a nonionic bactericidal agent that penetrates into the biofilm and sterilizes it, has been developed as a technology that has a high biofilm suppression effect that causes periodontal disease.

これに対して、本発明者らは、非殺菌的なプラークコントロール手段を検討した中で、アルギン酸プロピレングリコールエステルに、歯周病原因菌、特にポルフィロモナス ジンジバリス(Porphyromonas gingivalis)の歯面への付着を抑制する従来知られていない効果があり、プラークコントロールに有用であることを見出した。更に、このアルギン酸プロピレングリコールエステルを、難水溶性殺菌剤のイソプロピルメチルフェノールと組み合わせて配合した場合、これら両成分が相乗的に作用し、口腔内細菌の歯面付着抑制効果に優れると共に歯周病原性バイオフィルムへの高い殺菌効果が発揮され、よって、歯周病原性バイオフィルムの形成を抑制する高い効果を奏することを見出した。
なお、従来の技術から、アルギン酸プロピレングリコールエステルに歯周病原因菌の歯面付着抑制効果がありバイオフィルム殺菌効果の亢進作用を奏することは予測できない。

上記粘度は、BL型粘度計により測定した値であり、具体的には下記方法による測定値である。
また、アルギン酸プロピレングリコールエステルは、製品の種類に応じて1種又は2種以上併用して使用できる。
アルギン酸プロピレングリコールを4g採取し600mL容量のビーカーに入れ、そこに攪拌棒で攪拌しながら精製水396gを少しずつ加える。初めに少量の水でよく溶解し、ある程度溶けたら全量の水を入れる。その後1時間膨潤させ、1時間後、高速攪拌機(ホモミキサー)により12,000回転/分で1分間攪拌する。この溶液を300mLトールビーカーに入れて、20℃水槽に静置させておく。泡が上に上がり、ビーカーの溶液の色が透明になったら、上の泡を薬さじ等で取り除く。温度計をビーカーの中に入れて検液が20℃に達したことを確認し、粘度測定を行う。

表1に示す組成の試験組成物について、下記方法で歯周病原因菌の付着抑制効果を評価した。結果を表1に示す。
歯周病原因菌は、アメリカン タイプ カルチャー コレクション(ATCC)より購入したポルフィロモナス ジンジバリス(Porphyromonas gingivalis)ATCC33277株を用い、ヘミン及びメナジオンを含むトッドへーウィットブロース培養液(THBHM*1)により37℃で嫌気的条件下(80vol%窒素、10vol%二酸化炭素、10vol%水素)で定常状態まで培養し、550nmにおける吸光度が1.0になるようPBS(和光純薬工業社製)に懸濁した液を試験に供した。
付着担体は、直径7mm×厚さ3.5mmのハイドロキシアパタイト(HA)板(旭光学社製)を用い、0.45μmのフィルターでろ過したヒト無刺激唾液に1時間(37℃)浸漬し、HA表面を唾液成分でコートし試験に供した。
唾液コートしたHA板をPBS(和光純薬工業社製)で1回洗浄した後、表1~3に示す組成の試験組成物2mLに5分間浸漬した。処置後、PBSで1回洗浄後、HA板を前述したポルフィロモナス ジンジバリス菌液に30分間(37℃)浸漬した。その後、HA板はPBS 1mLで3回洗浄した後、PBS 4mL中で超音波処理(200μA、10秒間)により付着した細菌を分散し、PBSを用いて10倍段階希釈を施した。このものを10%綿羊脱繊血含有血液寒天平板*2に50μL塗沫し、嫌気性条件下で約2週間培養した。生育したコロニー数よりHA板に付着したポルフィロモナス ジンジバリスの菌数を求め、付着菌数をcfu(colony forming unit)/HA板として算出した。コントロールの付着菌数に対する試験組成物の付着抑制率を下記式により求め、下記基準に則り、歯周病原因菌付着抑制効果を判定した。
付着抑制率(%)=((コントロールの付着菌数-試験組成物の付着菌数)/(コントロールの付着菌数))×100
◎:付着抑制率が80%以上100%以下
○:付着抑制率が60%以上80%未満
△:付着抑制率が40%以上60%未満
×:付着抑制率が0%以上40%未満

表2、3に示す組成の試験組成物について、上記方法で歯周病原因菌の付着抑制効果を評価し、また、下記方法でモデルバイオフィルムに対する浸透殺菌効果を評価した。結果を表2,3に示す。
直径7mm×厚さ3.5mmのハイドロキシアパタイト(HA)板(旭光学社製)を0.45μmのフィルターでろ過したヒト無刺激唾液で4時間処理したものをモデルバイオフィルム作製の担体に用い、培養液には、ベイサルメディウムムチン培養液(BMM)*3を用いた。モデルバイオフィルムを作製するために使用した菌株は、American Type Culture Collectionより購入したアクチノマイセス ヴィスコサス(Actinomyces viscosus)ATCC43146、ベイヨネラ パルビュラ(Veillonella parvula)ATCC17745、フゾバクテリウム ヌクレアタム(Fusobacterium nucleatum)ATCC10953、ポルフィロモナス ジンジバリス(Porphyromonas gingivalis)ATCC33277を用いた。これら4菌株は予めBMM3,000mLを入れたRotating Disk Rector(培養槽)にそれぞれ1×107cfu/mL(cfu:colony forming units)になるように接種し、唾液処理したHA担体と共に37℃、嫌気的条件下(5vol%炭酸ガス、95vol%窒素)で24時間培養した。その後、同条件でBMM培地を置換率5vol%/時間の割合で連続的に供給し10日間培養を行い、HA表面に4菌種混合のモデルバイオフィルムを形成させた。
形成させたモデルバイオフィルムは24穴マルチプレート(住友ベークライト社製)に移し、表2、3に示した試験組成物2mLを加え3分間浸漬し、PBS(和光純薬工業社製)1mLで6回洗浄した後、同バッファー4mLを添加した試験管(直径13mm×100mm)内で超音波処理(200μA、10秒間)により分散した。この分散液をPBSで10倍段階希釈を施し、硫酸カナマイシン含有血液寒天平板*4に50μL塗沫し、嫌気的条件下で培養した。生育したコロニー数を計測し、モデルバイオフィルムあたりの歯周病細菌(ポルフィロモナス ジンジバリス)の生菌数(cfu/Biofilm)を求めた。
試験組成物のバイオフィルム殺菌効果は、下式によりコントロールに対する歯周病細菌の殺菌率を求め、この殺菌率から、下記基準に則りバイオフィルム殺菌効果を判定した。
歯周病細菌の殺菌率=コントロールの歯周病細菌数(cfu/Biofilm)/試験製剤の歯周病細菌数(cfu/Biofilm)
☆:歯周病細菌の殺菌率が1,000以上
◎:歯周病細菌の殺菌率が100以上1,000未満
○:歯周病細菌の殺菌率が10以上100未満
