Background: Management of orbitozygomatic fractures forms part of the scope of practice of many oral and maxillofacial surgeons. As aspects of management vary among surgeons who treat such injuries, this confidential study was undertaken to examine some of the protocols of Australian and New Zealand oral and maxillofacial surgeons.
Results: Eighty-one per cent of the respondents treated orbitozygomaticfractures and on average, each treated approximately 24 cases per year. Also, about one in five cases required orbital floor exploration.Further, the preferred imaging baseline was computed tomography plus plain X-rays, while the preferred implant materials for orbital floor reconstruction were autologous bone and resorbable membrane. The incidence of postoperative retrobulbar haemorrhage was estimated at approximately 1:1000.
Conclusion: Most oral and maxillofacial surgeons treat orbitozygomatic injuries as part of their surgical scope.

Due to their superior physicochemical features, chitosan thermosensitive hydrogels are multipurpose platforms that are frequently used in the biomedical industry. Many investigations have been conducted recently to modify their pore dimensions, expansion, biodegradability, stimulus-reaction characteristics, and other characteristics in order to better tailor them to the complex craniofacial tissues. They have been the focus of various studies that have attempted to load biological cargos for therapeutic and regenerative uses in the oro-facial tissues.

Objectives: To assess the long-term clinical outcomes and patient satisfaction with narrow-diameter implants (NDIs) in the posterior jaws and to identify the risk indicators for NDI failure.
Materials And Methods: This retrospective study reviewed 479 patients with 666 NDIs (diameter ≤ 3.5 mm) -supported fixed prostheses in posterior jaws, with a minimum 10-year follow-up.

Oral submucous fibrosis (OSF) is a chronic, progressive, and fibrotic condition of the oral mucosa that carries an elevated risk of malignant transformation. We aimed to identify and validate novel genes associated with the regulation of epithelial-to-mesenchymal transition (EMT) in OSF. Genes regulating EMT were identified through differential gene expression analysis, using a LogFC threshold of -1 and + 1 and a padj value < 0.

The objective of this study was to tailor an osteoinductive scaffold for alveolar bone regeneration and around immediately placed implants in extraction sockets of dogs. Tailored amorphous multiporous bioactive glass (TAMP -BG) was prepared and characterized for bioactivity and response of human alveolar bone marrow mesenchymal stem cells (hABMSCs). Extraction sockets of twenty-two male mongrel dogs received TAMP-BG in the right side around implant in the distal socket of the mandibular fourth premolar (P4), while the adjacent empty mesial socket of the same tooth was filled with the same graft.

Plp1-lineage Schwann cells (SCs) of peripheral nerve play a critical role in vascular remodeling and osteogenic differentiation during the early stage of bone healing, and the abnormal plasticity of SCs would jeopardize the bone regeneration. However, how Plp1-lineage cells respond to injury and initiate the vascularized osteogenesis remains incompletely understood. Here, by employing single-cell transcriptional profiling combined with lineage-specific tracing models, we uncover that Plp1-lineage cells undergoing injury-induced glia-to-MSCs transition contributed to osteogenesis and revascularization in the initial stage of bone injury.
