An increasing number of dental practices are upgrading from film radiography to digital radiography, for reasons that include faster image processing, easier image access, better patient education, enhanced data storage, and improved office productivity. Most practices that have converted to digital technology use rigid, or direct, sensors. Another digital option is flexible phosphor sensors, also called indirect sensors or phosphor storage plates (PSPs). Flexible phosphor sensors can be advantageous for use with certain patients who may be averse to direct sensors, and they can deliver a larger image area. Additionally, sensor cost for replacement PSPs is considerably lower than for hard sensors. As such, flexible phosphor sensors appear to be a viable supplement or option to direct sensors.

UNLABELLED: Digital x-ray systems offer advantages over conventional film systems, yet many dentists have not adopted digital technology. OBJECTIVES: To assess New Zealand dental practitioners' use of--and preferences for--dental radiography systems. DESIGN: Cross-sectional survey. SETTING: General and specialist dental practice. PARTICIPANTS AND METHODS: Postal questionnaire survey of a sample of 770 dentists (520 randomly selected general dental practitioners and all 250 specialists) listed in the 2012 NZ Dental Council Register. MAIN OUTCOME MEASURES: Type of radiography systems used by dentists. Dentists' experiences and opinions of conventional film and digital radiography. RESULTS: The participation rate was 55.2%. Digital radiography systems were used by 58.0% of participating dentists, most commonly among those aged 31-40 years. Users of digital radiography tended to report greater satisfaction with their radiography systems than users conventional films. Two-thirds of film users were interested in switching to digital radiography in the near future. Reasons given by conventional film users for not using digital radiography included cost, difficulty in integrating with other software systems, concern about potential technical errors, and the size and nature of the intra-oral sensors. CONCLUSION: Many dental practitioners have still not adopted digital radiography, yet its users are more satisfied with their radiography systems than are conventional film users. The latter may find changing to a digital system to be satisfying and rewarding.

Since the introduction of cone beam computed tomography (CBCT), this 3-dimensional diagnostic imaging technique has been established in a growing number of fields in dental medicine. It has become an important tool for both diagnosis and treatment planning, and is also able to support endodontic treatments. However, the higher effective dose of ionizing radiation compared to conventional 2-dimensional radiographs is not justifiable in every case. CBCT allows for a more precise diagnosis of periapical lesions, root fractures as well as external and internal resorptions. Concerning the utility of CBCT in treatment planning decisions, the gain of information through 3-dimensional imaging for any of these pathologies has to be evaluated carefully on an individual basis. Moreover, radioopaque materials such as root canal filling and posts often create artefacts, which may compromise diagnosis. The aim of this review is to summarize the possibilities and limits of CBCT imaging in endodontology as well as introduce guidelines for daily clinical practice. Furthermore, the article presents possible therapeutic advantages of preexisting CBCT scans for root canal treatments.

OBJECTIVE: The objective of this study was to compare dental radiographs printed on glossy paper from calibrated low-cost printers with monitor display. STUDY DESIGN: Three typical intraoral radiographs were selected and a questionnaire was developed with questions assessing accuracy and subjective quality. A test pattern was designed for printer calibration. After calibration, radiographs were printed on glossy paper with 3 ink-jet and 2 thermo-sublimation printers. Sixteen raters evaluated the printed radiographs, 9 of them also on standardized viewing monitors. Subjective ratings were compared, and an ROC-analysis based on expert-consensus monitor readings was performed. RESULTS: Low inter-rater reproducibility (mean Cohen's Kappa monitor: 0.49; printers: 0.44), but high diagnostic accuracy was found for all printers (areas [Az] underneath the ROC curves: 0.725 to 0.884). The overlap between the 95% Az confidence intervals of the mean indicate no significant differences. CONCLUSION: Our preliminary findings indicate that dental radiographs may be evaluated on glossy paper prints of calibrated customary printers.

PURPOSE: The purpose of this study was to determine the prevalence of digital radiography among dentists in Hawai'i and report their experiences using it. METHODS: A 20-question survey was developed and used to interview dentists in Hawai'i. Approximately 500 dentists were contacted. The survey asked whether or not the dentist uses digital radiography. For those not using digital equipment, reasons were given as well as proposed future use. For users of digital equipment, further information was requested: group or solo practice, length of time with digital equipment, length of time to decide, brand of dental software, brand and type of digital equipment, how many different systems, satisfaction, would they do it again, financially worth it, advantages, disadvantages, diagnostic or not, use of special features, sensor replacement and maintenance costs, and any other comments about digital radiography. RESULTS: 102 dentists responded to the survey. 36 percent utilize digital radiography. Only 40 percent of nonusers have any inclination of converting to digital, cost being the most common reason not to convert. Average length of time with digital was 3.4 years and about 2 years to make the decision. Dentrix was the most popular software and Dexis the most popular equipment. The overwhelming majority are satisfied with systems, feel they are financially worth it, feel it is diagnostic, and would purchase them again. Advantages included things such as speed, no use of chemicals, and lower radiation. Disadvantages included cost, sensor-related issues, and computer issues. Digital users find special features helpful and utilize them regularly. Maintenance costs include annual software upgrades, sensor replacement, and barriers and bitetabs. CONCLUSIONS: Digital radiography is becoming more prevalent in Hawai'i. The big obstacle seems to be cost for most dentists, although users believe it is a good financial investment.

OBJECTIVES: To determine dentists" perceptions of the usefulness of digital technologies in improving dental practice and resolving practice issues; to determine dentists" willingness to use digital and electronic technologies; to determine perceived obstacles to the use of digital and electronic technologies in dental offices; and to determine dentists" attitudes toward Internet privacy issues. METHODS: An anonymous, self-administered survey of Canadian dentists was conducted by mail. A potential mailing list of 14,052 active Canadian dentists was compiled from the 2003 records of provincial regulatory bodies. For each province, 7.8% of the dentists were randomly selected with the help of computer software. The surveys were mailed to this stratified random sample of 1,096 dentists. RESULTS: The response rate was 28% (312/1,096). Of the 312 respondents, 4 (1%) were in full-time academic positions, 16 (5%) were not practising, and 9 (3%) provided incomplete data. Therefore, 283 survey responses were available for analysis. More than 60% of the dentists indicated that computer technology was quite capable or very capable of improving their current practice by increasing patient satisfaction, decreasing office expenses, increasing practice efficiency, increasing practice production, improving record quality and improving case diagnosis and treatment planning. More than 50% of respondents reported that digital photography and digital radiography were quite useful or very useful. About 70% of the dentists agreed or strongly agreed with using digital and electronic technologies to consult with dental specialists. Cost of equipment and lack of comfort with technology were regarded as significant or insurmountable obstacles by substantial proportions of respondents. CONCLUSIONS: Respondents generally viewed digital and electronic technologies as useful to the profession. Increased office efficiency and production were perceived as positive effects of digital and electronic technologies. These technologies are more often used for consulting with colleagues rather than for consulting with patients. The major obstacles to the general use of these technologies were related to cost, lack of comfort with technology and differences in legislation between provinces and countries. Privacy issues were not perceived as a significant barrier.

PURPOSE: The purpose of this study was to: (1) determine the popularity of digital radiography among members of the American Academy of Pediatric Dentistry (AAPD); and (2) report the most common systems in use. METHODS: An AAPD-approved, voluntary, and anonymous electronic survey was developed and sent to 923 board certified pediatric dentists. Years in practice and in-office x-ray technology (digital or conventional) were inquired about initially. If negative for the use of digital radiography, future consideration for converting to digital radiography was ascertained. For positive responses, more in-depth information was requested. Information on type of system (sensor or phosphor plate), user friendliness, diagnostic ability, patient's comfort, general costs, durability, and parental and overall satisfaction was collected. For most of the questions, a 5-point assessment scale was used. Opportunity for additional comments was provided upon survey completion. Data was analyzed using descriptive statistics. RESULTS: A 32% (296/923) response rate was obtained. Twenty-six percent of practitioners (78/296) implemented digital radiography in their practices, whereas 71% considered future acquisition. Similar distribution for sensor and phosphor plate users was found. Sensor technology was reported to produce faster images, but was less tolerable by young children due to size and thickness. Phosphor plates were considered more children friendly, less expensive, and less durable. Parental satisfaction was very high with great marketing value. Picture quality was comparable to conventional film. Overall, digital radiography users would recommend it to other pediatric dentists. CONCLUSIONS: Digital radiography is not yet popular among pediatric dentists. Cost reduction and technology advancement may enhance utilization.
