Cleft lip and palate (CL/P) are prevalent congenital anomalies with complex genetic causes. The G874A mutation of T-box transcription factor 22 (TBX-22) gene is notably associated with CL/P, while the underlying mechanism remains to be clarified. Studies have shown that the restriction of epithelial-mesenchymal transformation (EMT) process in medial edge epithelial cells (MEEs) is crucial for CL/P development.

Objectives: In advanced stages of osteoradionecrosis, medication-related osteonecrosis of the jaw, and osteomyelitis, a resection of sections of the mandible may be unavoidable. The determination of adequate bony resection margins is a fundamental problem because bony resection margins cannot be secured intraoperatively. Single-photon emission computed tomography (SPECT-CT) is more accurate than conventional imaging techniques in detecting inflammatory jaw pathologies.

A calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic tumour of epithelial origin accounting for approximately 1% of all odontogenic tumours. The intraosseous form occurs more commonly in the posterior mandible whereas the extraosseous form is common in the anterior maxilla. CEOT is often asymptomatic and presents with a painless swelling of the mandible.

This study examined the effects of treadmill running (TR) regimens on craniofacial pain- and anxiety-like behaviors, as well as their effects on neural changes in specific brain regions of male mice subjected to repeated social defeat stress (SDS) for 10 days. Behavioral and immunohistochemical experiments were conducted to evaluate the impact of TR regimens on SDS-related those behaviors, as well as epigenetic and neural activity markers in the anterior cingulate cortex (ACC), insular cortex (IC), rostral ventromedial medulla (RVM), and cervical spinal dorsal horn (C2). Behavioral responses were quantified using multiple tests, while immunohistochemistry measured histone H3 acetylation, histone deacetylases (HDAC1, HDAC2), and neural activity markers (FosB and phosphorylated cAMP response element-binding protein (pCREB).

Background: Head and neck free flap reconstruction presents challenges in managing intraoperative circulation, potentially leading to prolonged length of stay (PLOS). Limited research exists on the associations between intraoperative circulation and PLOS given the difficulty of manual quantification of intraoperative circulation time-series data. Therefore, this study aimed to quantify intraoperative circulation data and investigate its association with PLOS after free flap reconstruction utilizing machine learning algorithms.

Revascularization of an Autotransplanted Mature Tooth After Extraoral Root Resection: A Case Report.

Case Rep Dent

January 2025

Institute of Dentistry and Oral Sciences, Faculty of Medicine, Palacky University, Olomouc, Czech Republic.

The outcome of tooth autotransplantation depends mainly on the transplant tooth's anatomy-the type of donor tooth and the developmental stage of root formation. Mature teeth display a higher complication rate due to lower pulp revascularization potential, requiring root canal treatment (RCT) pre- or postoperatively to avoid postoperative complications, which extends treatment duration and cost. This report details a 39-year-old patient's autotransplantation of a mature wisdom tooth to replace the first molar after unsuccessful root canal retreatment.

Objective: Imbalanced autonomic nervous system (ANS) activity raises concerns about the development of systemic complications during dental treatment. The purpose of this study was to determine whether a psychological test (Toho Medical Index (TMI)) prior to the impacted mandibular third molar extraction can identify patients with potentially imbalanced autonomic function.

Materials And Methods: In this prospective study, 34 healthy adult patients with no history of systemic disease were assigned to either the autonomic imbalance group (type II, III, IV) or the control group (type I) based on the results of the TMI.

Edentulous patients with history of cleft palate and severe maxillary atrophy are challenging patients to rehabilitate through an oral approach. The difficulty of rehabilitating these patients lies in the unusual anatomy they present and the alteration of the vascular supply of local tissues caused by the previous performed surgeries, along with other causes. This report describes the successful dental rehabilitation with zygomatic implants of a patient with complete bilateral cleft palate who was edentulous and had severe maxillary atrophy.

Novel transcripts of EMT driving the malignant transformation of oral submucous fibrosis.

Sci Rep

January 2025

Department of Oral and Maxillofacial Pathology and Microbiology, Manipal College of Dental Sciences, Manipal Academy of Higher Education, Manipal, 576104, India.

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.

Enhancer-driven Shh signaling promotes glia-to-mesenchyme transition during bone repair.

Bone Res

January 2025

Jiangsu Province Key Laboratory of Oral Diseases, Nanjing, Jiangsu Province, China.

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.

Unbalanced redox homeostasis leads to the production of reactive oxygen species and exacerbates inflammatory bowel disease. To investigate the role of the transcription factor Nrf2, a major antioxidative stress sensor, in intestinal epithelial cells (IECs), we generated IEC-specific Nrf2 gene knock-in mice (Nrf2-vRes), which express Nrf2 only in IECs, using the cre/loxp system. Colitis was induced in wild-type (WT) mice, whole-body Nrf2-knockout (Nrf2-KO) mice, and Nrf2-vRes mice by administering dextran sulfate sodium (DSS) for 1 week (acute model) or intermittently for 5 weeks (chronic model).

Proposal of staging system and treatment guideline for diagnostically challenging primary intra-osseous carcinoma: A retrospective single-center case series and literature review.

J Stomatol Oral Maxillofac Surg

January 2025

Department of Oral and Maxillofacial Surgery, School of Dentistry, Seoul National University, Seoul National University Dental Hospital, Seoul, 03080, South Korea; Department of One-Stop Specialty Center, Seoul National University Dental Hospital, Seoul, South Korea. Electronic address:

The objective of this retrospective study is to examine the clinical, imaging and pathologic features of 10 patients diagnosed with 'primary intraosseous carcinoma (PIOC)' at a single institution and to identify factors affecting the prognosis of PIOC patients. By proposing a new staging system based on tumor size, cortical bone deformation, neck metastasis and histologic grade, the study aims to address the lack of a distinct staging system, which has led to the mixed use of oral squamous cell carcinoma classification. Furthermore, the study intends to propose a treatment guideline based on the newly proposed staging system.
