Abstract
Description
しかし、歯ブラシ器具による洗浄方法の実施状態は、個人差が大きく、適切な洗浄方法を実施できている人は多くはない。そのため、口腔内に固定され、口腔内のミュータンス菌を直接殺菌できる口腔内固定用組成物が望まれている。
開示の口腔内固定用組成物は、口腔内に脱離不能な状態で固定され、カルシウムハイドロキシアパタイトのカルシウムの一部をチタンに置換してなるチタンアパタイトを含有する。
開示の口腔内固定用組成物は、カルシウムハイドロキシアパタイトのカルシウムの一部をチタンに置換してなるチタンアパタイトを含有する。
前記口腔内固定用組成物は、口腔内に脱離不能な状態で固定される。ここで、「脱離不能」とは、前記口腔内固定用組成物を口腔内に固定している本人の意志では取り外せないことを意味する。言い換えれば、前記口腔内固定用組成物とは、歯科医の治療によって口腔内に固定される口腔内固定用組成物である。
なお、前記口腔内固定用組成物は、歯科補綴物ともいう。
本発明者らは、鋭意検討を行った結果、人間の口腔内に生息するミュータンス菌が分泌する酸によって低pHとなる環境においても前記チタンアパタイトが光触媒機能を発揮して前記ミュータンス菌を分解することを見出した。
更に、本発明者らは、前記チタンアパタイトがカルシウムハイドロキシアパタイトと比べて耐酸性に優れることを見出した。
カルシウムハイドロキシアパタイトは、あらゆる酸に対して容易に溶解するが、本発明者らが検討した結果、前記チタンアパタイトは、通常の酸には溶解せず、200℃の熱濃硫酸を用いて初めて溶解する。
前記インレー及び前記クラウンとは、歯牙に窩洞又は支台歯が形成された後、その窩洞又は支台歯に適合するような形態に調節された修復物をいう。歯牙の欠損が少ない場合には、通常、インレーによる修復が行われ、歯牙の崩壊が大きく、インレーではもとの歯牙の形を再現することができない場合には、クラウンによって歯牙全体を覆い、修復が行われる。前記クラウンには、ブリッジも含まれる。
前記クラウンの一例を図1及び2に示す。図1及び2において、符号1は、クラウンを示す。
欠損部を有する歯の斜視図を図3に示す。図3に示す歯の欠損部にインレーを嵌め合わせた図を図4に示す。図3及び4において、符号3は、歯を示す。図4において、符号2は、インレーを示す。
前記インプラント義歯とは、歯が欠損した部位の顎骨内にインプラントフィクスチャーを埋入しそのインプラントフィクスチャーに固定する義歯である。
前記口腔内固定用組成物は、カルシウムハイドロキシアパタイトのカルシウムの一部をチタンに置換してなるチタンアパタイトを含有している。
前記カルシウムハイドロキシアパタイト(CaHAP)は、吸着性に優れるカルシウム原子(Ca)及び生体親和性が良好なリン原子(P)を含み、例えば、Ca10(PO4)6(OH)2で表される。
Ti(チタン)が、前記カルシウムハイドロキシアパタイト(CaHAP)の結晶構造を構成する金属原子の一部として結晶構造中に取り込まれる(置換等される)こと、例えば、Ca(カルシウム)サイトの一部がTi(チタン)によって置換されることによって、前記チタンアパタイトの結晶構造中には、光触媒機能を発揮し得る光触媒性部分構造が形成される。
前記チタンアパタイトの平均粒径が、5μmを超えると、口腔内固定用組成物への練り込み状態または表面コーティング状態を好適に維持することができないことがある。
口腔内において前記口腔内固定用組成物に紫外線を照射する方法としては、特に制限はなく、目的に応じて適宜選択することができ、例えば、紫外線を照射する発光ダイオードなどを用いて口腔内の前記口腔内固定用組成物に紫外線を照射する方法などが挙げられる。なお、口腔内の前記口腔内固定用組成物以外の部位に紫外線を照射したくない場合には、口腔内の前記口腔内固定用組成物以外の部分をアルミニウム箔などで覆ってもよい。
チタンアパタイトとして、カルシウム・チタンハイドロキシアパタイト(TiHAP;太平化学産業株式会社製、PHOTOHAP PCAP-100、粒子径3μm~8μmの白色粉体)を用いた。
ミュータンス菌(Streptococcus mutans)を3.0×105個含む培養液(乳酸によりpH4.0に調整:口腔内環境を想定)を収容した透明容器に、前記チタンアパタイト1.0gを投入して、ブラックライト(0.5mW/cm2)により紫外線を照射して、ミュータンス菌の生存率を調べた。結果を図5に示す。
また、ミュータンス菌(Streptococcus mutans)を3.0×105個含む培養液(乳酸によりpH4.0に調整:口腔内環境を想定)にチタンアパタイトを投入しなかったブランクにも、ブラックライト(0.5mW/cm2)により紫外線を照射して、ミュータンス菌の生存率を調べた。結果を図5に示す。
培養液にチタンアパタイトを投入しなかったブランクでは、紫外線照射4時間においても、ミュータンス菌の生存率が初期の65%であったのに対して、培養液にチタンアパタイトを投入した場合には、紫外線照射1時間でミュータンス菌の生存率が初期の30%まで減少し、紫外線照射4時間でミュータンス菌の生存率が0%になった。
このことから、口腔内の低pH環境において、チタンアパタイトがミュータンス菌を分解することが確認できた。
カルシウム・チタンハイドロキシアパタイト(TiHAP;太平化学産業株式会社製、PHOTOHAP PCAP-100、粒子径3μm~8μmの白色粉体)1.0gを、乳酸によってpH4.0にした36℃の酸性水溶液(ミュータンス菌が排出する酸による口腔内環境に相当)10mLに浸漬し、カルシウム・チタンハイドロキシアパタイトの溶解量を測定した。1時間後の溶解量は、6質量%であった。
カルシウム・チタンハイドロキシアパタイトを、カルシウムハイドロキシアパタイト(HAP100、太平化学産業株式会社製)に変えた以外は上記と同様にして、カルシウムハイドロキシアパタイトの溶解量を測定した。1時間後の溶解量は、45質量%であった。
以上より、チタンアパタイトは、口腔内環境において、耐酸性に優れることが確認できた。
カルシウム・チタンハイドロキシアパタイト(TiHAP;太平化学産業株式会社製、PHOTOHAP PCAP-100、粒子径3μm~8μmの白色粉体)を練り込んだハイブリッドセラミッククラウン(セラミックとレジンとのハイブリッド)を準備した。
