Video-based teleradiology for intraosseous lesions. A receiver operating characteristic analysis

Teledentistry: a systematic review of the literature

We conducted a systematic review of teledentistry applications. We searched the MEDLINE/PubMed, Embase and Cochrane Library databases for relevant articles published from 1992 to 2012. The reference lists of all retrieved articles were hand-searched. Studies were included after assessing the eligibility of the full-text article. A total of 878 studies were identified, of which 59 fulfilled the inclusion criteria of the review. The articles covered several dental specialties, mostly oral surgery, oral medicine and oral pathology. The most common type of teledentistry application was education (n = 21), followed by diagnosis (n = 16), consultation (n = 3) and treatment (n = 2). Teledentistry studies were reported in a total of 15 countries. The largest number of studies were conducted in the US (n = 22) and there were no studies from developing countries. Most of the reports referred to pilot projects and short-term outcomes, and most of the studies were descriptive. The review indicates that although teledentistry is an area of expansion, there are still some barriers to its increased use.

Email for distance diagnosis of oral diseases: a preliminary study of teledentistry

We examined the feasibility of distance diagnosis of oral diseases, using transmission of digital images by email. Twenty-five cases of oral lesions were documented during a 12-month study in a primary care public health clinic in Paraná in Southern Brazil. Clinical electronic charts and images were produced and sent by email to two oral medicine specialists with a median of 10 years experience in the field. The consultants provided a maximum of two clinical hypotheses for each case. In 15 of the 25 cases (60%) both consultants made a correct diagnosis; in seven cases (28%) only one consultant made a correct diagnosis; and in three cases (12%) neither consultant made a correct diagnosis. Thus in 88% of cases, at least one consultant was able to provide the correct diagnosis. The results suggest that distant diagnosis can be an effective alternative in the diagnosis of oral lesions and that the using two distant consultants improves diagnostic accuracy. Primary care public health clinics may benefit from the use of email and digital cameras for telehealth in remote areas where oral medicine specialists are not available.

Telemedicine in Maxillofacial Trauma: A 2-Year Clinical Experience

PURPOSE

The authors report the 2-year experience of use of the PATATRAC telemedicine system in managing maxillofacial trauma.

MATERIALS AND METHODS

Thirty-five regional hospitals on-line with PATATRAC in the period from January 2002-January 2004 have sent 18 consultations (11 men and 7 women) to the Maxillofacial Surgery Division of San Giovanni Battista Hospital in Turin for telemedicine evaluation of patients with maxillofacial trauma.

RESULTS

Only 50% of the consultations (9 patients) sent via PATATRAC indicated maxillofacial treatment, and only one case resulted in immediate transfer. Of the remaining 8 transfers, 2 patients were transferred after treatment of associated lesions in the receiving hospital, and the other 6 patients were transferred as scheduled based on the availability of beds in the specialist center.

CONCLUSIONS

The results obtained, despite the poor number of telemedicine maxillofacial consultations, have mainly proved the usefulness of PATATRAC in drastically reducing expensive and unnecessary transfers of maxillofacial patients, without indications for either immediate or deferred treatment, thus also avoiding discomfort to the patient with other injuries.

MedView: an instrument for clinical research and education in oral medicine

The etiology for many of the mucosal lesions we encounter in clinical practice is frequently uncertain or unknown and there is reason to believe that multicausality plays an important role. To detect multicausal relationships, the analysis must include multiple variables and large amounts of data. A traditional retrospective analysis is often based on a limited number of variables and frequently entails methodological errors where vital information may be missing. Prospective studies may be hampered by the fact that the prevalences of many conditions are relatively low. The search for new knowledge in oral medicine should therefore be facilitated by prospective use of formalized information gathered in multicenter studies. MedView is a computer program that is based on formalized input and registration of all clinical information. The output applications are focused on visualization and statistical analysis. MedView is aimed at clinical research and is well suited for multicenter studies. It also contains applications for education and distant consultations.

Clinical decision-making using computers: opportunities and limitations

This paper deals with the use of information technology in order to make clinical decisions in dentistry. Since there is a large number of available systems and ongoing projects using computers, we first identify and describe major streams, as well as singular specialties. We underline the need for standards for data format and exchange in addition to the ability of different systems to communicate with each other. We conclude with a five-step recommendation to transform a dental office into digital and how to implement a computer-aided clinical decision support system, which provides action-oriented support in order to reduce the likelihood of human error during dental treatment.

Level of diagnostic confidence, accuracy, and reasons for mistakes in teleradiology for minor injuries

The objective of this study is to determine whether eliminating uncertainty in diagnosis improves accuracy in teleradiology for remote trauma management and to assess the correlation between the probable reason for the mistake and the level of confidence. An emergency physician interpreted 2133 radiological series transmitted from a community hospital to an emergency department using videoconferencing equipment. He marked his level of confidence as 1 = sure positive; 2 = fairly sure positive; 3 = unsure; 4 = fairly sure negative; 5 = sure negative. The emergency physician also entered free-text comments, e.g., feeling tired, to enable a better understanding of what was happening. The accuracy, sensitivity, and specificity were 97.3% (98.6%), 94.48% (96.72%), and 98.63% (99.42%), respectively. Figures in brackets represent the 93.5% of cases in which the level of confidence was graded as sure. Boredom and hurry were the main reasons identified for mistakes. Reducing uncertainty in diagnosis may improve the accuracy of screen interpretation. This first series must be reproducible by others before any general use of such systems can be made for primary diagnosis. American College of Radiology standards must be met.

Are photographic records reliable for orthodontic screening?

AIM

The aim of the study was to evaluate the reliability of a panel of orthodontists for accepting new patient referrals based on clinical photographs.

SAMPLE

Eight orthodontists from Greater Manchester, Lancashire, Chester, and Derbyshire observed clinical photographs of 40 consecutive new patients attending the orthodontic department, Hope Hospital, Salford.

METHOD

They recorded whether or not they would accept the patient, as a new patient referral, in their department. Each consultant was asked to take into account factors, such as oral hygiene, dental development, and severity of the malocclusion.

STATISTICS

Kappa statistic for multiple-rater agreement and kappa statistic for intra-observer reliability were calculated.

RESULTS

Inter-observer panel agreement for accepting new patient referrals based on photographic information was low (multiple rater kappa score 0.37). Intra-examiner agreement was better (kappa range 0.34-0.90).

CONCLUSION

Clinician agreement for screening and accepting orthodontic referrals based on clinical photographs is comparable to that previously reported for other clinical decision making.

Accuracy of diagnosis of fractures by maxillofacial and accident and emergency doctors using plain radiography compared with a telemedicine system: a prospective study

Ten facial radiographs with fractures and 10 without fractures were viewed by eight oral and maxillofacial surgery (OMFS) and eight accident and emergency (A&E) doctors who were each asked questions about the presence and site of any fractures as well as the quality of the images and diagnostic confidence. Each radiograph was then transmitted over a teleradiology link and viewed by the same OMFS doctors who answered the same questions. The position of the fracture was more accurately assessed using plain radiography. Diagnosis by OMFS doctors using telemedicine was broadly comparable with fracture diagnosis by A&E doctors using plain radiography. Poor quality radiographs and frontozygomatic and infraorbital rim fractures were poorly diagnosed by telemedicine. This telemedicine system was a useful tool to aid diagnosis of most facial fractures. The need for appropriate clinical information is vital. Diagnosis of frontozygomatic and infraorbital rim disruption using telemedicine is less reliable than plain radiography.

Videoconferencing: what are the benefits for dental practice?

For more than 3 years members of the TeleDent team from Bristol University have been looking at the potential of videoconferencing technology for dentistry. Here they explain what videoconferencing is and how it can help the GDP. They discuss examples of its most promising uses for the profession, which include professional updating and providing diagnostic support at a distance. They describe the equipment that is needed, the different types of system available and give an indication of costs. A suggested procedure for using the technology for remote referrals is outlined. 'Store and forward' techniques are also discussed. These do not involve a live video but involve the sending of static electronic files. This approach is compared with videoconferencing, and the article looks at the question of which will be best suited to the GDP, and for what purposes.

Interpretation of artificial and in vivo periapical bone lesions comparing conventional viewing versus a video conferencing system

The purpose of this study was to compare the interpretation of conventional radiographs transmitted by a video teleconferencing system to conventional viewbox interpretation for both artificial and in vivo periapical bone lesions. A total of 30 radiographic images were used in this study: 20 radiographic images of artificial lesions and 10 radiographs from actual patients. Two endodontists evaluated the 30 images by giving a "yes" or "no" response when determining whether a periapical lesion was present on the radiograph. The study was conducted in two sessions, separated by a 6-wk interval to minimize evaluator recall. Results of the study revealed no statistical difference between the ability of the evaluator to identify periapical bone lesions using conventional radiographs on a viewbox and his ability to interpret the same images transmitted on a monitor screen.
