Article Synopsis
- The study aimed to determine if a low-dose cone-beam computed tomography (CBCT) protocol could provide sufficient image quality for evaluating bone healing after alveolar bone grafting in patients aged 7-14 with orofacial clefts.
- The research involved 11 patients who were assessed using both standard-dose and low-dose CBCT protocols during a follow-up at 6 months post-surgery.
- Results showed that while there were no significant differences in most measured parameters between the two protocols, observers felt less confident when assessing images taken with the low-dose method.
Comparison of absorbed doses and organ doses measured with thermoluminescent dosimeters and Gafchromic film for cone beam computed tomography examination of the posterior mandibular region in a head phantom.

Article Synopsis
- The study aimed to compare the effectiveness of two dosimetry methods, thermoluminescent dosimeters (TLDs) and Gafchromic film, in measuring absorbed doses during CBCT scans of the mandibular third molar region.
- TLDs were placed at 75 points on a head phantom, and results showed a strong correlation with Gafchromic film measurements, particularly at lower doses.
- However, significant discrepancies were found in minimum and maximum doses, indicating that Gafchromic film is a more reliable option for monitoring absorbed doses in dental imaging.
Objective: Optimization of radiographic examinations is essential for radiation protection. The objective of the study was to investigate the clinical applicability of a low-dose CBCT protocol as compared to the default for pre-surgical evaluation of mandibular third molars.
Material & Methods: Forty-eight patients (62 teeth) referred for pre-surgical mandibular third molar investigation were recruited after justification for CBCT.
Objectives: To query the experience of oral surgeons concerning referral routines and preferences for radiographic imaging modality before surgical removal of mandibular third molars and investigate factors that influence imaging modality preferences.
Materials And Methods: Members of the Swedish Association of Oral and Maxillofacial Surgeons (n = 280) were invited to participate in a web-based digital survey concerning their experiences and use of three imaging modalities in pre-surgical assessment of mandibular third molar removal. The survey comprised multiple-choice questions and four cases depicted in images; respondents reported whether they would supplement the cases with other images and, if so, from which modality.
Objectives: The aim was to evaluate the characteristics of the mandibular third molars, especially in relation to the inferior alveolar nerve. Further aims were to investigate incidental findings in panoramic radiographs in an adult population, and to investigate image quality related to patient positioning.
Materials And Methods: From a previous study with 451 randomly selected adult participants who lived in Sweden, 442 panoramic radiographs from four dental public health clinics were used.
