Abstract
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.
