“…Between January 2010 and December 2018, 246 patients (155 female and 91 male) were treated with Xgeva ® for bone metastases (120 mg Denosumab every 4 weeks) or giant cell bone tumor (120 mg Denosumab every 4 weeks with 2 additional doses of 120 mg in the first month of treatment). The median follow-up time was 16 months (IQR [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]). At the last follow-up, 38 patients (24 female and 14 male) developed MRONJ.…”

“…CBCT is more sensitive than PR, particularly with regard to periosteal reaction, bone sequestration, and cortical lysis [ 17 , 18 ]. In the recent study of Santos et al [ 19 ] CBCT is compared with PR in the management decision for MRONJ. As a result, half of the dentists of the study changed their management after analysis of CBCT versus PR.…”

“…Moreover, in comparison with CT scans, CBCT provides a higher spatial resolution that improves the image quality with lower radiation dosages than regular CT scans [ 20 ]. As imaging techniques and knowledge evolved, CBCT is now considered to be the gold standard in dental and maxillofacial sectional imaging [ 19 ].…”

Medication-related osteonecrosis of the jaw (MRONJ) is a severe side effect of antiresorptive medication. The aim of this study was to evaluate the incidence of denosumab-related osteonecrosis of the jaw and to compare the clinical and radiological extent of osteonecrosis. A retrospective study of patients who received Xgeva® at the Institut de Cancérologie de Lorraine (ICL) was performed. Patients for whom clinical and radiological (CBCT) data were available were divided into two groups: “exposed” for patients with bone exposure and “fistula” when only a fistula through which the bone could be probed was observed. The difference between clinical and radiological extent was assessed. The p-value was set at 0.05, and a total of 246 patients were included. The cumulative incidence of osteonecrosis was 0.9% at 6 months, 7% at 12 months, and 15% from 24 months. The clinical extent of MRONJ was significantly less than their radiological extent: in the “exposed” group, 17 areas (45%) were less extensive clinically than radiologically (p < 0.001) and respectively 6 (67%) for the “fistula” group (p < 0.031). It would seem that a CBCT is essential to know the real extent of MRONJ. Thus, it would seem interesting to systematically perform a CBCT during the diagnosis of MRONJ, exploring the entire affected dental arch.

“…Aside from diagnostic imaging and clinical laboratory tests [ 1 ], biopsies are essential diagnostic measures for pathologies [ 2 , 3 ]. Clinicians may face many challenges when performing osseous biopsies on the lower jaw due to its individual anatomy and the presence of anatomical structures such as nerves and tooth roots [ 4 ].…”

Biopsies of osseous jaw lesions using 3D-printed surgical guides: a clinical study

et al. 2022

Background Bone biopsies are often necessary to make a diagnosis in the case of irregular bone structures of the jaw. A 3D-printed surgical guide may be a helpful tool for enhancing the accuracy of the biopsy and for ensuring that the tissue of interest is precisely removed for examination. This study was conducted to compare the accuracy of biopsies performed with 3D-printed surgical guides to that of free-handed biopsies. Methods Computed tomography scans were performed on patients with bony lesions of the lower jaw. Surgical guides were planned via computer-aided design and manufactured by a 3D-printer. Biopsies were performed with the surgical guides. Bone models of the lower jaw with geometries identical to the patients’ lower jaws were produced using a 3D-printer. The jaw models were fitted into a phantom head model and free-handed biopsies were taken as controls. The accuracy of the biopsies was evaluated by comparing the parameters for the axis, angle and depth of the biopsies to the planned parameters. Results Eight patients were included. The mean deviation between the biopsy axes was significantly lower in guided procedures than in free-handed biopsies (1.4 mm ± 0.9 mm; 3.6 mm ± 1.0 mm; p = 0.0005). The mean biopsy angle deviation was also significantly lower in guided biopsies than in free-handed biopsies (6.8° ± 4.0; 15.4° ± 3.6; p = 0.0005). The biopsy depth showed no significant difference between the guided and the free-handed biopsies. Conclusions Computer-guided biopsies allow significantly higher accuracy than free-handed procedures.

“…Although panoramic radiography was considered for several decades ago and till now the main radiographic modality for examining the jaw bones. However, cone beam computed tomography (CBCT) is one of the most promising imaging modalities nowadays in the dental domain (10)(11)(12) . Its applications in dental and maxillofacial fields increase and grow progressively (13)(14)(15)(16) .…”

Purpose: Idiopathic osteosclerosis is a common radiopaque lesion without clear cause that affects the mandible and maxilla. This study was conducted to assess the prevalence of idiopathic osteosclerosis in the jaws among Egyptian population. Subjects and Methods: 1100 CBCT scans were used to assess the prevalence, gender and age distribution, location, and size of idiopathic osteosclerosis. Results: Idiopathic osteosclerosis was found in 16.7% of the cases with equal distribution in males and females patients, especially, in the third decade. Mandibular lesions were found in 95.7% of them, 52.7% in molar region and 29.9 % in premolar region. The size ranged from 1.5-15.6 mm. Conclusion: Idiopathic osteosclerosis is not uncommon radiographic finding in Egyptian population with predilection to premolar-molar mandibular region.
