“…25 Whether a difference in radiation dose is reflected in the image quality and the diagnostic outcome was not investigated, nor was this issue within the scope of the present study. A previous study by Molander et al 4 concluded that Scanora (dental) provided the best subjective image quality.…”

Objective: During dental radiography, the salivary and thyroid glands are at radiation risk. In 2007, the International Commission on Radiological Protection (ICRP) updated the methodology for determining the effective dose, and the salivary glands were assigned tissue-specific weighting factors for the first time. The aims of this study were to determine the absorbed dose to the organs and to calculate, applying the ICRP publication 103 tissue-weighting factors, the effective doses delivered during digital intraoral and panoramic radiography. Methods: Thermoluminescent dosemeter measurements were performed on an anthropomorphic head and neck phantom. The organ-absorbed doses were measured at 30 locations, representing different radiosensitive organs in the head and neck, and the effective dose was calculated according to the ICRP recommendations.

“…These values are slightly higher than measurements found in other studies using the Rando adult phantoms and TLDs [6,[17][18][19][20][21]. In a study by Davis et al, [22] the effective dose measured using a short collimator was 7.7 microsieverts.…”

Panoramic radiographs are valuable and technically easy procedures in determining lesions and the other pathological conditions of the jaw. However, it should be recognized that there are obvious limitations in these films. These limitations include distortions, magnifications, and difficulties in identifying the relationship of the lesions with vital structures.This study presented two cases that indicated the limitations of panoramic radiographs. In the first case, a radiolucent lesion was detected on panoramic radiography. The borders of the lesion were associated with the mandibular canal and mental foremen. In the second case, two radiolucent areas were seen on panoramic radiography. They were determined to be in relation to the maxillary sinus and mental foramen. Following the screening panoramic examination, cone beam computed tomography (CBCT) was obtained in both of the cases. The CBCT views demonstrated no relationship between the lesions and the anatomical structures detected in the panoramic radiographs.In conclusion, using only panoramic radiographs is not enough for the detection of the anatomic relationships and borders of the lesions. We suggest that dentists need 3D images to provide the correct information for presurgical assessments.
