Dental Imaging - A basic guide for the radiologist.

BACKGROUND

As dental imaging accounts for approximately 40 % of all X-ray examinations in Germany, profound knowledge of this topic is essential not only for the dentist but also for the clinical radiologist. This review focuses on basic imaging findings regarding the teeth. Therefore, tooth structure, currently available imaging techniques and common findings in conserving dentistry including endodontology, periodontology, implantology and dental trauma are presented.

METHODS

Literature research on the current state of dental radiology was performed using Pubmed.

RESULTS AND

CONCLUSION

Currently, the most frequent imaging techniques are the orthopantomogram (OPG) and single-tooth radiograph, as well as computer tomography (CT) and cone beam CT mainly for implantology (planning or postoperative control) or trauma indications. Especially early diagnosis and correct classification of a dental trauma, such as dental pulp involvement, prevents from treatment delays or worsening of therapy options and prognosis. Furthermore, teeth are commonly a hidden focus of infection.Since radiologists are frequently confronted with dental imaging, either concerning a particular question such as a trauma patient or regarding incidental findings throughout head and neck imaging, further training in this field is more than worthwhile to facilitate an early and sufficient dental treatment.

KEY POINTS: · This review focuses on dental imaging techniques and the most important pathologies.. · Dental pathologies may not only be locally but also systemically relevant.. · Reporting of dental findings is important for best patient care..
