“…Cross-contamination in dental radiology is of a great concern, particularly when intraoral radiographs are used because intraoral films are a source of contamination for the radiographic processor resulting in cross-contamination of subsequent films which pose a threat to subsequent patients [ 2 , 3 ]. Also other areas in dental radiology operatory, such as X-ray cone and control panel, may become contaminated during X-ray imaging procedure [ 2 , 4 , 5 ].…”

“…Guidelines of infection control are well established in many parts of the world; however, compliance with these guidelines is still of a concern. Many previous studies focused on the importance of infection control in dental radiography worldwide [ 2 – 4 , 11 – 15 ]. However, few studies evaluated the compliance of dental radiographers of infection control measures [ 11 , 13 , 16 ], and these studies were limited to the evaluation of the use of protective barriers.…”

Objectives. To assess the level of dental radiographers’ compliance with infection control measures and to evaluate the factors affecting their compliance. Methods. The study included 175 dental radiographers. Compliance with infection control was evaluated with a self-administered questionnaire consisting of 33 questions related to vaccination, hand hygiene (HH), personal protective equipment (PPE), disinfection and sterilization, and use of surface barriers. Pearson’s chi-square test was used to compare compliance between subgroups of radiographers. Results. 64.6% of participants were females, and 62.9% was younger than 30 years. 13.0% of the sample population had >10 years of experience and 28.0% take radiographs for >20 patients/day. 66.9% of participants wash their hands before/after taking radiographs. 26.3% of participants had vaccination against hepatitis B, tetanus, and tuberculosis. 12.6% fully use PPE, 10.9% perform complete disinfection and sterilization, and 16.0% apply all kinds of surfaces barriers. Vaccination was significantly affected by age, gender, and practice type. HH was affected by years of experience and number of patients radiographed per day. PPE was influenced by number of hours worked per week and patients radiographed daily. Disinfection and sterilization was affected by practice type and years of experience. The use of surface barriers was affected by age, practice type, and number of patients radiographed/day. Conclusions. The current study indicated poor compliance with infection control practices among dental radiographers. We recommend continuing educational programs and training courses to increase dental radiographers’ awareness of local and international infection control guidelines and to enhance their implementation of these guidelines.

“…9 This is unsatisfactory because bacteria on radiographic films survive processing. 10 An alternative is to place films in a plastic protective cover before they are inserted in the mouth. The wrapping should be discarded prior to development.…”

Although dental radiology is not directly involved in either invasive procedures or in the use of piercing-cutting material, the high-touch areas of dental x-ray device, including radiographic films, are a potential source of infection. The purpose of this study was to assess the amount of cross infection present in the dental x-ray devices of the School of Dentistry of the Federal University of Maranhão by investigating the presence of pathogenic microorganisms in high-touch areas of dental x-ray devices (tube head, timer button, portable processing box and lead apron). Twenty surfaces of 4 dental radiology clinics were cultured in different media. The results showed that 70 percent of the surfaces had contamination. All the dental x-ray devices assessed were contaminated (tube head, timers or both) as well as all the lead aprons. The portable processing boxes showed 75 percent of contamination. The groups found no statistical significance between the different surfaces assessed and the microorganisms. The highest frequent microorganisms found were from Staphylococcus genus. The authors concluded that because of the high incidence of contamination found, the x-ray devices used in the dental clinics could be at potential risk of cross infection, demonstrating the necessity for applying biosecurity practices when taking radiographic and during radiographic processing.
