“…The present study showed that the absorbed dose to the parotid gland, zygomatic bone, oral mucosa and upper central tooth are similar to other studies (13,34) in case of using CBCT and the panorama respectively, based upon publication ICRP -103 (2007) (13,35) . The dose of panorama was considerably lesser than that causing from CBCT.…”

Purpose:The goal of the this study is to measure absorbed dose of oral tissues such as oral mucosa, salivary gland and bone after exposure to ionizing radiation through panoramic radiograph and cone beam CT. Subjects and Methods: about 50 Egyptian patients were selected in this study who were referred to the department of oral medicine, periodontology, oral diagnosis & radiology, Faculties of Dental Medicine, Al-Azhar university for panoramic or cone beam examination for various dental purposes. Patients were divided into two groups (25 patients each). First Group was subjected to panoramic examination and the second one was subjected to cone beam examination. The systems used were a Planmeca Viso CBCT and Orthopantomogram OP-100 panorama. Assessment of the patient radiation dose was done by thermoluminescent dosimeter (TLD) on the patients. The absorbed radiation dose is then recorded. Data was then analyzed, and statistical calculations were performed. Results: The absorbed radiation skin doses ranged between (130 µGy, 2817.8 µGy) in panorama and (327.99 µGy, 11994 µGy) in CBCT for one exposure. When digital panoramic unit and CBCT were compared, panoramic imaging is 25-37% of CBCT. Parotid gland and oral mucosa absorbed the greatest radiation dose for all panoramic and CBCT patients. CBCT radiation doses are considerably higher than those of digital panoramic unit. Conclusion: The prospective benefits of CBCT in maxillofacial disciplinary are undoubted; but, it is important that their use be totally justified above conventional technique before they are done.

“…For the tube voltage, the mean value of the exceeding-the-DRL group (84.4 kVp) was higher than that of the below-the-DRL group (72.7 kVp) by 11.7 kVp. These findings are also higher than the values reported in recent studies from other countries, which have reported a mean tube voltage of 68.1-71.3 kVp (15)(16)(17)(18) . All seven units (17%) with a tube voltage exceeding 90 kVp in this study were being used with their HD mode engaged as standard exposure conditions, and all were in the exceeding-the-DRL group.…”

“…ESD value was up to 3.3 times greater in the oral mucosa when the DAP was at the maximum than at the minimum. Moreover, similar to the study by Zamani et al (18,19) , since the eyeball dose was high as that of the oral mucosa or thyroid dose, an appropriate method for eyeball dose reduction was particularly necessary.…”

Attribution of the rise in radiation dose to the relaxed panoramic radiography diagnostic reference level in Korea the DRL of other countries (e.g., 81 mGy*cm 2 in the United Kingdom, 100 mGy*cm 2 in the United States, and 120 mGy*cm 2 in Finland) (11)(12)(13) , few studies have investigated the cause of the increase in DRL. Furthermore, a study that investigated 125 (1.4%) of 8,772 units (as of March 2019) said to exist in Korea may not be a representative cohort (9) . This study investigated the use of panoramic radiography at dental clinics within a district in Korea, measuring the dose area product (DAP) and comparing the recommended values with the 2019

Objective This study aimed to investigate and compare the mandibular radiomorphometric characteristics of patients with unilateral or bilateral cleft lip and palate (CLP) with those of individuals without CLP and to determine whether there was a difference. Design Retrospective cohort study. Setting Orthodontic Department in Faculty of Dentistry. Patients and Interventions Mandibular cortical bone thickness was measured on high-quality panoramic radiographs taken from 46 patients with unilateral or bilateral CLP aged 13–15 years and 21 control patients. Main Outcome Measures Three radiomorphometric indices [antegonial index (AI), mental index (MI), and panoramic mandibular index (PMI)] were measured bilaterally. AutoCAD software was used for MI, PMI, and AI measurements. Results Left MI values were significantly lower in individuals with unilateral cleft lip and palate (UCLP; 0.029 ± 0.04) than in individuals with bilateral cleft lip and palate (BCLP; 0.033 ± 0.07). In addition, right MI values of individuals with right UCLP (0.26 ± 0.06) were significantly lower than those of individuals with left UCLP (0.34 ± 0.06) or BCLP (0.32 ± 0.08). No difference was observed between individuals with BCLP and left UCLP. These values did not differ between groups. Conclusions Antegonial index and PMI values did not differ between individuals with different types of CLP or when compared with control patients. In patients with UCLP, cortical bone thickness was found to be reduced on the cleft side compared to the intact side. Patients with UCLP with a right-sided cleft had a more substantial decrease in cortical bone thickness.
