“…According to a joint statement by the American Association of Endodontists and the American Academy of Oral and Maxillofacial Radiology in 2015, the optimal imaging choice for root canal evaluation is intraoral X-ray [24]. Therefore, image quality often influences dentists' diagnosis and treatment methods.…”

The objective of this study was to develop a geometrical calibration method applicable to the 2.5D prototype Periapical Radiography System and estimate component position errors. A two-steel-ball phantom with a precisely known position was placed in front of a digital X-ray sensor for two-stage calibration. In the first stage, the following three parameters were estimated: (1) r, the distance between the focal spot and the rotation axis of the X-ray tube; (2) ψ, the included angle between the straight line formed by the X-ray tube’s focal spot and rotation axis and the straight line of the orthogonal sensor; and (3) L4, the distance between the rotation axis and the plane where the two steel balls were positioned. In the second stage, the steel balls’ positions were determined to calculate the positions of the X-ray tube on the x, y, and z axes. Computer simulation was used to verify the accuracy of the calibration method. The results indicate that for the calibration approach proposed in this study, the differences between the estimated errors and setting errors were smaller than 0.15% in the first and second stages, which is highly accurate, verifying its applicability to accurate calibration of the 2.5D Periapical Radiography System.

“…Patients most frequently decide to see a dentist because of pain complaints, and the difficulties in locating the canal ostia force dentists to consult specialists who diagnose a dysplasia based on a characteristic X-ray image (panoramic radiograph). Previously, such extraoral images were the main source of information about the status and the anatomy of patient's teeth; however, at present, in each case of suspected complex structure of pulp cavities it is recommended to perform a CBCT scan [8]. The CBCT scan makes it possible to precisely determine the degree of dental canal obliteration and the place where denticles occur, which increases the chance of proper treatment.…”

This paper describes a rare case of genetically determined dentin dysplasia type I in 26-year-old male patient. The paper highlights anatomical and radiological aspects of dental abnormalities and emphasizes the significance of the education of both general practitioners and paediatricians as regards referring patients with diagnosed dentin dysplasia for a multi-specialty therapy.

“…Thus, although it offers a more effective diagnostic imaging tool in endodontic therapy, CBCT exposes the patient to a higher radiation dose than conventional radiography. Moreover, clinical findings and dental X-rays may be sufficient to make an informed diagnosis, so CBCT should only be used after careful consideration 5) . Proper removal of bacteria is crucial when performing root canal therapy.…”

“…Conventional diagnosis of apical periodontitis has been based on clinical findings and dental X-rays. The big advantage of dental X-rays is that exposure to radiation can be kept to a minimum; the disadvantage is that it is impossible to manipulate those images, which means that experience is needed if the results are to be interpreted accurately 5,11) . In recent years, dental cone beam computed tomography (CBCT) has been used as an effective diagnostic tool in endodontic therapy.…”

Apical periodontitis is usually diagnosed based on clinical findings and dental X-rays. Recently, however, dental cone beam computed tomography (CBCT), which provides 3-D images of the maxillofacial region, has enabled dentists to examine patients undergoing endodontic therapy more effectively, improving diagnostic accuracy. Here, we describe a positive treatment outcome achieved using CBCT to diagnose apical periodontitis of the maxillary premolars, which had proven difficult to diagnose based on clinical findings and dental radiography alone. The patient was a 42-year-old Japanese man who presented with the chief complaint of gingival swelling in the maxillary right premolar region. Our initial diagnosis, based on clinical findings and dental X-ray, was apical periodontitis of the maxillary right second premolar, and treatment was started. However, after the patient failed to respond to the treatment, CBCT was performed. Based on these new findings, the diagnosis was changed to one of apical periodontitis of the upper right first premolar, and the patient was treated accordingly. Previous studies have described the complex anatomical morphology of the upper premolars, noting multiple roots and variation in the morphology of the root canals. The 3-D images provided by dental CBCT allow better assessment of oral conditions than the traditional 2-D images provided by dental X-rays, which in turn enables the dentist to better select the most appropriate treatment. Here, the patient showed no symptoms and was progressing well at a 6-month follow-up visit. The present results indicate that when clinical findings and dental X-rays alone are insufficient to allow a secure diagnosis, CBCT offers an effective alternative which will enable the appropriate treatment to be selected more reliably.
