RESUMO

OBJECTIVE: This study aimed to compare the bone density and volume in patients with alveolar cleft reconstructions utilizing bone marrow aspirate concentrate with iliac graft versus iliac graft alone. MATERIAL AND METHODS: Thirty-six patients with unilateral alveolar cleft were randomly allocated into either an intervention group receiving an iliac bone graft mixed with bone marrow concentrate or a control group receiving an iliac bone graft. Cone beam CT was obtained preoperative, 6 and 12 months postoperatively to assess the bone density of the graft and bone volume of the alveolar defect, and then, the bone loss ratio was calculated. RESULTS: Bone volume and bone density demonstrated a statistically significant increase in the intervention group at 6 and 12 months. In contrast, the bone loss ratio decreased significantly in the intervention group throughout the follow-up period. CONCLUSION: A combination of bone marrow concentrate and iliac cancellous bone in alveolar cleft reconstruction may improve bone densities and volume in addition to decreasing graft loss rate. CLINICAL SIGNIFICANCE: Using of bone marrow aspirate concentrate will decrease the amount of the graft needed and decrease the ratio of bone loss at the grafted site by the time. Trial registration ClinicalTrials.org ( NCT04414423 ) 4/6/2020.

RESUMO

PURPOSE: The recent coronavirus disease (COVID-19) pandemic mainly affects the respiratory system; however, several oral and maxillofacial post-COVID-19 complications have also been observed. This series reports the growing number of osteonecrosis cases associated with post-COVID-19 patients. MATERIALS AND METHODS: This is a retrospective, multi-center case series that reports cases with maxillary osteonecrosis after various periods of SARS-CoV-2 infection in the period between January and August 2021 based on the PROCESS guidelines. RESULTS: Twelve cases were reported with post-COVID-19 manifestation of spontaneous osteonecrosis of the maxillary jaw. Five patients were hospitalized during COVID-19 management and all of the twelve cases had at least one systematic Co-morbidity, and undertake corticosteroids prescription based on the COVID-19 disease treatment protocol. The mean onset of osteonecrosis symptoms appearance was 5.5 ± 2.43 weeks calculated from the day of the negative PCR test. The management was successfully done through surgical debridement and pre and post-operative antibiotics. No anti-fungal medications were prescribed as the fungal culture and the histopathological report were negative. CONCLUSION: Post-COVID-related osteonecrosis of the jaw (PC-RONJ) could be now considered as one of the potential post-COVID-19 oral and maxillofacial complications that occurs unprovokedly and mainly in the maxilla.
