まとめ
再利用された歯科用ハンドピースは,B型肝炎 (HBV) やヒト免疫不全ウイルス (HIV) などのウイルスを患者間で宿し,感染させることがあります. 徹底した清掃と熱処理は,交叉汚染のリスクを防ぐために不可欠です.
科学分野:
- 感染症 感染症は感染症です.
- 歯科公衆衛生 歯科公衆衛生について
- バイオメディカルエンジニアリング
背景:
- 再利用された歯科器具,特にハンドピースは,潜在的な交叉汚染の危険性があります.
- 内部メカニズムは患者の材料を収容し,B型肝炎 (HBV) やヒト免疫不全ウイルス (HIV) を含む病原体の伝播を促進します.
研究 の 目的:
- 再利用された歯科用ハンドピースと予防の角度から,交叉汚染のリスクを評価する.
- これらのデバイスが,ウイルスDNAを含む,患者由来の汚染物質を吸収し,排出できるかどうかを判断する.
主な方法:
- 新しい予防対策の角度と高速ハンドピースに関する実験室と臨床試験が行われました.
- ヒト特異性DNA,HIV前ウイルスDNA,HBVDNAは,患者で使用され,感染した血液と接触したデバイスからのサンプルで検査されました.
- バクテリオファージ phi X174は,ウイルス粒子の回復をテストするモデルウイルスとして使用されました.
主要な成果:
- 患者の治療中に,ハンドピースの中にヒトDNAとHIVDNAが検出され,ハンドピースから排出されました.
- HBV DNAは,感染した血液と接触した後に,ハンドピースと付属のホースで発見された.
- 感染性のバクテリオファージ粒子は,内部メカニズム,ホース,排出された水噴霧から回収されました.
結論:
- 再利用された歯科用ハンドピースや予防用アングルは,感染病原体を伝染させる可能性があります.
- 感染リスクを軽減するために,患者の間での効果的な清掃と熱処理が推奨されます.
- 排気ガスと空気/水路からの汚染リスクに対処するためにさらなる研究が必要である.

Handwashing I: Introduction and Types of Equipment
Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated.

Cleaning, Sterilization, and Disinfection
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Standard Precaution
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Transmission-based Precautions I: Contact, Enteric, and Droplets
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
