ABSTRACT
Benign fibro-osseous lesions are a diverse range of entities that have distinct clinical and radiographic features. They can occur as solitary lesions or concomitant with other pathologies as hybrid lesions. Fibrous dysplasia (FD) accompanied by central giant cell granuloma (CGCG), peripheral giant cell granuloma (PGCG) or peripheral ossifying fibroma (POF) as hybrid lesions, is reported very rarely in the literature. Although we were unable to find any reports of FD with PGCG as a hybrid lesion. Fibro-osseous lesions have certain histopathological features in common with PGCG including multinucleated giant cells. Here we report a 28 year old female with a painless, slow growing and pedunculated swelling of the maxilla for 18 months. Differential diagnosis consisted of FD, cemento-ossifying fibroma (COF), chondrosarcoma and probable PGCG considering radiographic and clinical investigations. Histopathologic findings revealed PGCG and FD as a hybrid lesion. The combination of PGCG and FD has not been reported in the literature so far.
ABSTRACT
Statement of the Problem: For many years, practitioners have been encountered with dental rehabilitation of atrophic jaws. Among many of alternatives, free iliac graft can be a reasonable and also problematic choice to be accomplished. Purpose: The aim of this study was to evaluate the implant survival rate and bone loss in implants inserted in reconstructed jaws with free iliac graft. Materials and Method: In this clinical trial study, twelve patients that underwent bone reconstruction with free iliac graft were included in this retrospective study. The patients underwent surgery over a 6-year period from September 2011 to July 2017. Panoramic images were taken immediately after implant insertion and at the follow-up session. The parameters that were assessed included implant survival rate, bone level changes, and surrounding tissue conditions. Results: One hundred and nine implants were placed in eight female and four male patients, of which 65 (59.6%) were inserted in the reconstructed maxilla and 44 (40.3%) in the reconstructed mandible. The interval between the reconstruction surgery and follow-up session was 28.75 months and the mean interval between implant insertion and the follow-up session was 21.75 months, ranging from 6 to 72 months. The total average of crestal bone resorption was 2.44 mm (range: 0 to 5.43 mm). Conclusion: This study found that rehabilitation of atrophic jaws with dental implants placed in free iliac graft was associated with acceptable marginal bone loss, survival rate, satisfaction, and esthetic results among the patients.
ABSTRACT
BACKGROUND: It was aimed to investigate the musculoskeletal status in individuals diagnosed with skeletal discrepancies. METHODS: This case-control study was performed on 35 patients with developmental skeletal discrepancies listed for orthognathic surgery as a case group and 33 patients who were nominated for wisdom tooth removal as a control group. All participants were aged 18-40 years and the research was carried out in the period between May 2018 and May 2019. Dual X-ray absorptiometry (DEXA) was used to assess bone mass density at three bone sites: total hip, femoral neck, and the spinal lumbar vertebrae (L1-L4). The appendicular muscle mass index (ASMI) was measured based on the four limbs from the DEXA scan. RESULTS: Our data showed that 45.7% (16) of the case group were osteopenic or osteoporotic while in the control group only 21.2% (7) were osteopenic in at least one region (total hip, femoral neck, or lumbar) (p-value = 0.03). Regarding muscle mass, there was significantly lower SMI in subjects with skeletal discrepancies (case group) compared with the control group (median (IQR) 5.9 (2.5) vs. 6.8 (2.9) (kg/m2), respectively, p = 0.04). CONCLUSIONS: There is an essential need for more studies to understand the exact interrelationship between musculoskeletal status and skeletal jaw discrepancies.
