MELVILLE, New York — (June 24, 2013) — Air Techniques, Inc., a leading innovator and manufacturer of dental equipment, announced today the introduction of its ScanX® size 2 barrier envelope bulk pack. This new package contains 1,000 envelopes compared to 300 envelopes in the non-bulk pack. Show Barrier envelopes are used with phosphor storage plates to help prevent cross-contamination. Air Techniques recommends using their brand of ScanX barrier envelopes with its phosphor sensors. The rounded corners and soft edges compliment the sensors shape and provide maximum patient comfort. Air Techniques’ barrier envelopes are disposable, odor-free and open effortlessly. The innovative, patented Y-notch design and center seam allow you to open the envelope without hassle and without ever touching the plate. “We’re excited about our new ScanX Barrier #2 Barrier Envelopes bulk pack. Not only is it more cost-effective for our customers, but it also takes up less space in the operatory,” said Nicole Miller, Air Techniques Product Manager. Air Techniques barrier envelopes feature a transparent side for accurate phosphor sensor positioning, and an opaque side to prevent ambient light from reaching the sensitive side of the imaging plate. The barrier envelopes will help prolong the life of the plate. Air Techniques barrier envelopes ensure the utmost hygiene when handling phosphor sensors and placing them into the patient’s mouth.

Patented envelope design allows easy opening and ejecting of PSPs in a way that minimizes cross contamination of the transfer box or tray. Clear side shows plate orientation. Soft, super thin edges. Compatible with any film holder. 300 per pack. When taking dental radiographs, there is significant potential for cross-contamination of equipment and environmental surfaces with blood and/or saliva if proper aseptic techniques are not practiced. Dental healthcare personnel (DHCP) also can be at risk. Research indicates that oral micro-organisms can remain viable on inert radiographic equipment for up to 48 hours. Similar microbes have been shown to survive in x-ray developer/fixer for periods as long as 2 weeks.1-4 Infection control practices for dental radiography are identical to those used in the operatory. They are grounded in the practice of standard precautions and are directed toward preventing disease transmission from patients to DHCP, from DHCP to patients, from patient to patient, and from the practice to the surrounding locale.1-3 For infection control during radiographic procedures, a variety of procedures and materials are used, including use of (1) disposable and heat-sterilizable x-ray accessories; (2) immersion of heat-sensitive items in liquid chemical sterilants/high-level disinfectants; (3) surface covers and intermediate-level chemical disinfectants for clinical contact surfaces; (4) engineering and work practice controls; (5) personal protective equipment (PPE) and (6) DHCP training.1-3 The central element or greatest risk factor is the handling of exposed radiographic films. Limiting the spread of body fluids present on such films is an essential activity. Film packs used intraorally become contaminated, then they are handled and transported throughout the practice environment. Also important is the covering or decontamination of soiled items. There are many surfaces that could be touched and become contaminated, including tube heads, extension cones, control panels, exposure buttons, chair controls, film processors, surfaces in darkrooms, and any area touched by contaminated film, gloved hands, or equipment used orally.2-4 Infection control procedures for dental radiography can be divided into segments or components. These include activities before taking radiographs, activities performed while taking a radiograph, things to do after radiographs have been taken, and finally, tasks associated with film processing. All suggested activities first discussed apply to the taking of standard intraoral x-rays using film held within barrier protective pouches. Some films come pouched by the manufacturer, or pouches can be purchased separately and films can then be placed into them.2-4 Advice on using x-ray films without barrier pouches, taking panoramic/cephalometric x-rays, using a daylight loader for processing, and the use of digital radiography sensors will then be provided. USING INTRAORAL FILMS HELD WITHIN BARRIER POUCHES
Preparing to Take Dental Radiographs Covers generally involve plastic sheets, tubes, or pieces with adhesive edges. Examples of surfaces best covered include chair headrest and control adjustments, exposure buttons, control panels, and x-ray tube heads and yokes.2-4 Unit-dosing reduces the need to leave the immediate area in search of needed items, and it decreases the chances of DHCP contaminating large boxes or storage containers of materials while searching. Unit-dosing also reduces the chances of cross-contamination of environmental surfaces. Items best taken from a centralized supply area and unit-dosed include paper towels, mouth props, film holders (eg, cups), gloves, surface covers, film packs, and cotton rolls. Such items can be collected, stored, or segregated through the use of small plastic drinking cups.2-4 Film barriers have distinct advantages. First, barriers protect films from direct contamination. Second, barriers reduce the time needed for preparation and processing by eliminating the need for disinfection in the darkroom and the necessity of wearing additional pairs of gloves. Film barriers are the method of choice, especially when using daylight loaders. Their use eliminates almost all potential for equipment contamination.2-4 After the patient has been seated, hands can be washed, dried, and gloves placed. Then, heat-sterilized x-ray holding/positioning devices can be removed from their packages and assembled in view of the patient.2,3 Taking Dental Radiographs After Taking Dental Radiographs Developing Dental Radiographs
USING INTRAORAL FILMS NOT HELD WITHIN BARRIER POUCHES PANORAMIC/ CEPHALOMETRIC X-RAYS PROCESSING X-RAY FILMS IN A DAYLIGHT LOADER Daylight loaders commonly have cloth or rubber sleeves, cuffs, or flaps. These are used to allow for the passage of materials in and out of the daylight loader without allowing light to enter. This means that the equipment is difficult or impossible to clean or disinfect. Therefore, it is imperative that an effective yet efficient protocol for aseptic use be established and rigorously maintained. After reviewing the following steps, it should be obvious how useful barrier protected films are2-6 (Table 7). DIGITAL X-RAYS AND OTHER TECHNOLOGIES
Digital radiographic sensors and other high-technology instruments such as intraoral cameras, electronic periodontal probes, colossal analyzers, and lasers come into contact with mucous membranes. Such devices are considered to be semi-critical items. Ideally, they should be cleaned and heat-sterilized or high-level disinfected between patients. However, many cannot be heat-sterilized or undergo high-level disinfection. Semi-critical items that cannot be reprocessed by heat sterilization or high- level disinfection should at a minimum be barrier-protected by using a FDA-cleared barrier to reduce gross contamination. Covers are not always totally protective. Therefore, after removing the barriers, devices should be cleaned and disinfected using an intermediate level disinfectant (tuberculocidal) after each patient. Manufacturers should be consulted as to sterilization and disinfection processes as well as to the types of covers to be used.1-6 SUMMARY References
