Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology INFLUENCE OF THE MEDICAL AND DENTAL HISTORY ON THE RADIOGRAPHIC INTERPRETATION

Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology

Background

Medical history can have a positive influence on a radiologists’ interpretations, leading to a more useful report for the clinician. However, the medical history should not dictate the radiologic interpretation. We conducted a pilot study among the dentists practicing at the University of Florida to observe the influence of the patients’ medical and dental histories on the differential radiologic interpretation.

Objective(s)

The aim of this study was to observe the influence of the medical and dental histories on radiologic interpretation, and the variation depending on the dental specialty and the dentist's years of experience; and to encourage the dental practitioner to follow a systematic diagnostic strategy to avoid bias caused by the patient's medical and dental histories during radiologic interpretation.

Study Design

Dentists practicing at the University of Florida College of Dentistry were randomly divided into 4 equal groups of equal number. A survey email was sent to these groups, containing a case presentation with a pantomograph, intraoral photographs, and a medical history. The medical history was intentionally changed in each group to observe if this influenced the answers chosen by the dentists.

Results

A percentile-based descriptive analysis and a χ2 analysis demonstrated that the majority of the participating dentists were biased by the medical and dental histories provided. A correlation analysis revealed a weak relationship between the answers chosen by the participating dentists and their dental specialty and years of experience.

Discussion/Conclusions

Knowledge of oral and maxillofacial radiology and accurate medical and dental histories are indispensable for an appropriate radiologic interpretation. However, to avoid bias from the medical and dental histories during radiologic interpretation, the dentist should strategically do the radiologic interpretation first, correlate with clinical findings, come up with potential differential interpretations, and finally correlate the medical history with the interpretation to establish the final diagnosis
