Electronic Dental Records (EDR): 'Open Source' and Commercial-Off-The Shelf (COTS) Solutions
Shepherdstown 23 August 2010Approximately 90 percent of all dentists in the U.S. now use computers in their practice. Dental informatics, a subfield of health informatics, is focused on the application of computers, telecommunications, and information science to improve all aspects of dental practice, including management, clinical care, education, and research. Use of electronic dental record (EDR) systems can boost a practice's bottom line, while directly benefiting patients. They can help reduce operating costs, streamline workflow, improve quality of care, and enhance patient safety. This article is designed to offer a high level overview on the development of computerized dental systems to date, highlighting examples of selected 'open source' and commercial-off-the-shelf (COTS) solutions. The article also offers a set of conclusions on the current state of dental information systems and a number of management recommendations.
A dentist is a medical professional who has advanced knowledge of teeth, gums and mouth care and dental science. Two classifications for dentists include Doctor of Dental Surgery (DDS) and Doctor of Medical Dentistry (DMD). Dental hygienists and dental assistants within dental offices do many of the routine tasks such as dental cleanings, taking X-rays, simple maintenance and educating patients in sound oral hygiene practices.
Dentists care not only for teeth and gums, but also for the muscles and bones within or supporting the mouth. They may also perform surgeries within or around the mouth to promote dental health, improve appearance and prevent disease. The majority of dentists are private practitioners.
Software Solutions - Overview & Examples
The dental software industry has grown considerably over the past several decades. There are currently well over 40 commercial vendors that provide dental practice management, electronic dental record systems, and dental imaging systems for dental offices. Some of the leading commercial dental systems companies include Dentrix, Patterson Eaglesoft, Easy Dental, SoftDent, and PracticeWorks.
In a 2006, a JAMIA article entitled "Clinical Computing in General Dentistry", reported that 80 percent of all dental practices they surveyed were using a dental practice management systems. The article also reported that 70 percent of the dental offices surveyed used at least one other clinical software application, e.g. digitized dental imaging. The study also reported that approximately 25 percent of all general dentists were using a computer at chair side. More recent articles report the number has grown, with approximately 90 percent of all dental practices now using computerized dental systems. See http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1513654/
Three major categories of dental information have tended to dominate the field of dental informatics - practice management systems, electronic dental record (EDR) systems, and dental imaging systems. Practice management systems are primarily focused on patient demographics, appointment scheduling, billing, and management reports. Electronic Dental Record (EDR) systems are used to record diagnoses, dental history, progress notes, treatment plans, allergies and other clinical information. Dental imaging systems are used to capture, store and display digitized dental images and x-rays. Imaging systems are often interfaced with the practice management of EDR systems.
Practice Management & EDR Systems
Practice Management Systems are now installed in well over 80 percent of dental offices in the U.S. Electronic Dental Record (EDR) systems are currently installed in approximately 40 percent-60 percent of dental offices.

Other Dental Systems
Personal Health Record (PHR) systems are broader than a facility's electronic medical record (EMR). The PHR should contain any information relevant to an individual's health, including dental information, eye exams, etc. The Medicare.Gov web site on PHRs advocates that dental data ought to be included in PHRs, including dental insurance information. See
Google Health allows you to select and self-enter a limited number of dental conditions and procedures from a drop-down box, as well as dental insurance information, into one's personal health record. See www.google.com/health/
MS HealthVault allows you to self-enter any condition or procedure you want in free text, this could include dental information. There doesn't appear to be a place to enter dental insurance information at this time. Visit http://www.healthvault.com
While patient interaction with PHR systems is still very limited, the National Dental EDI Council (NDEDIC) has recognized their importance and begun to focus on ensuring the participation of dental insurance stakeholders in the development of PHR systems.
The ability to move dental information between EHR, EDR, and PHR systems via a health information exchange (HIE) network is needed and growing in importance.
The National Dental Electronic Data Interchange Council (NDEDIC) provides a community portal created to facilitate the exchange of information and unite stakeholders advancing the value and utilization of electronic connectivity in the dental community.
The Dental Caucus, an informal industry group, brings together electronic data interchange (EDI) network stakeholder organizations to encourage the efficient utilization of EDI and to seek out enhancements and solutions that are designed to improve the interconnectivity process. It is especially interested in providing dental and dental benefits industry input into the ASC X12 standards-making process. See http://www.x12.org/x12org/industry/index.cfm
Utah Health Information Network (UHIN) - UHIN is an example of a state health information network that supports the dental community and is focused on helping to reduce costs for dental practices. Dental claims, payments, reports, and x-rays can be transferred electronically through UHIN. Electronic transactions are formatted in a national ANSI or X12file format. This ensures that anyone that is receiving or sending transactions can expect that the data will be in the same place in the file.

Conclusions & Recommendations
The following are a number of general observations, conclusions and recommendations by the author with regards to Dental Informatics:
The Dental profession has stepped out ahead of their physician counterparts with regards to the use of computer systems. Over 80 percent of dental offices currently use practice management systems and over 70 percent are using other software modules such as dental imaging or electronic dental records (EDR). Physicians and medical informaticists may want to look to the field of dental informatics for 'best practices' and 'lessons learned' in implementing information systems.
A focus on consumers and personal health record (PHR) are the next frontier to be conquered. All PHR systems need to capture a range of standardized dental information, from particular dental conditions and procedures to insurance and claims data, in addition to other medical and health related information. As patients become more focused on preventive health care, they will want to start carefully tracking the type of procedures performed, their frequency, and costs.
There has been considerable progress on data standards and mechanisms needed on electronic data interchange (EDI) of dental claims information. As the National Health Information Network (NHIN) continues to evolve, additional efforts need to be made to enhance the standards and capabilities of EHR, EDR, and PHR systems so they can exchange a wider range of detailed medical and dental data elements, including digitized dental images.
A new phenomenon is the emergence of free or lower cost 'open source' dental software solutions. This mirrors what is happening in the computer software industry as a whole. This should prove helpful to small practices that have been reluctant to make the somewhat costly investment in dental information systems, in the U.S. and around the world.
There needs to be increased collaboration between medical and dental informaticists on a wide range of solutions such as - PHR systems; HIE networks; mobile Health Apps; architecture & standards; privacy & security; and the creation of public health databases that contain both medical and dental information for use by public health organizations and researchers.
