Abstract

The quality and the standard of the waterin dental units became scientifically andlegally important together with the report ofthe microbiological contamination of thewater in the dental unit system, Recently, itis known that an active biofilm within dental unit waterlines can be a potential sourceof cross infection for both the patients andthe dentistry staff. In this review the formation of biofilm within the dental unit waterlines, the microbiological evaluation of thedental unit waterlines system, and the risksof the biofilm within the dental unit waterlines for both the patients and the dentistrystaff have been analyzed. The commonresult in the literature for this issue is to prevent the formation of biofilm or annihilatethe present biofilm which can be a causefor cross infection. Altough there are various methods, the practicability and the permanence of these methods are important

Abstract

Difl ünitine gelen suyun mikrobiyolojik kontaminasyonunun önceki çalıflmalardarapor edilmesiyle birlikte sistemdekullanılan suyun kalite ve standardı bilimselve hukuki açıdan önemli bir yapıkazanmıfltır. Günümüzde difl üniti su yoluboyunca geliflmifl aktif bir biofilmtabakasının hem hastalar hem de diflhekimliği çalıflanları için potansiyel birçapraz infeksiyon kaynağı olduğu bilinmektedir. Bu derlemede difl üniti su yolunda biofilm oluflumu, difl üniti su yolununmikrobiyal yapısı, difl üniti su yolundakibiofilmin hastalar ve diflhekimliği personeliiçin oluflturduğu riskler ele alınmıfltır.Literatürde bu konuya yönelik olarakvarılan ortak sonuç çapraz infeksiyonkaynağı olan biofilm oluflumunun önlenmesi veya mevcut olanın yok edilmesidir.İzlenecek değiflik yöntemler olmakla birlikte önemli olan bu uygulamaların kolay vekalıcı olmasıdır."
