This paper presents an alternate view of current preclinical education in Operative Dentistry and suggests a course that uses a cause and appropriate response action rather than the traditional material specific cavity preparation. This approach considers caries as a disease, could foster a better understanding of prevention and its application in maintaining teeth for a lifetime for the patient, and encourage critical thinking for both student and faculty.

In operative dentistry x-ray films play an important part as a diagnostic procedure. Image quality depends on factors such as exposure and projection but also on optimum processing of the x-ray film. Of particular importance among the exposure-related factors are such features as variable voltage, short exposure time and narrow focussing. According to the new regulations in Germany x-rays may be used if this is indicated for medical reasons in dentistry. This condition is given far more frequently than x-rays are performed in the dental office. In the diagnosis of caries individual bitewing radiographs, if indicated, should always be preferred over panoramic radiographs. In pulp diseases radiographs may aid in detecting chronic pulpitis and in differential diagnosis with apical periodontitis. Both for diagnosis and documentation on intraoral films, tooth fractures are best imaged using two different projections. Radiovisiography facilitates radiographic diagnosis by employing a simple technique and operating with considerably lower doses.
