Digital radiography: a survey of dentists in Hawai'i.

Abstract

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.
