Furthermore, the perforation rate may vary by material type or barrier thickness, but previous reports have not addressed these issues. This high perforation rate of the plastic barrier brings the safety of the single-barrier technique into question. 2, 3 Hokett et al 2 reported a perforation rate of 44–51% when using a single plastic barrier under clinical conditions and recommended the use of a latex finger cot to significantly reduce the perforation rate. Limited literature is available on the effectiveness of an intraoral direct digital sensor barrier. Therefore, it is important to protect digital sensors by using barriers. However, currently, there is no intraoral digital sensor that can withstand heat sterilization or be completely immersed in a high-level disinfectant. 1 Ideally, these semicritical devices should be heat-sterilized or high-level disinfected between patients to prevent cross infection. Unlike film-based imaging, intraoral digital sensors are used repeatedly and infection control has become an increasingly important issue.Īccording to the guidelines of the Center for Disease Control and Prevention (CDC), these digital radiographic sensors are classified as semicritical devices, because they have contact with mucous membranes. Because of these benefits, digital radiography has replaced film radiography in dental practice. In addition, images can be stored permanently without any degradation of quality. Furthermore, the elimination of chemical processing and processing errors saves time and reduces radiation exposure. To begin with, digital radiography has a wider dynamic range therefore, the radiation exposure to patients can be reduced. Digital radiography has several advantages over film radiography. Digital radiography has now become widely accepted in the field of dentistry and has led to many changes in oral and maxillofacial radiology.
