To the Editor:The jaw cyst is one of the most common benign tumors in the oral and maxillofacial region.[1]To date,several studies have reported on jaw cysts in general populations from Italy,Brazil,Greece,and the United States in accordance with the 4th World Health Organization(WHO)classication of head and neck tumors.[2]However,there are no clinicopathological studies of odontogenic and non-odontogenic cysts in a large Chinese population in relation to the latest WHO classi***,few epidemiological studies have analyzed treatment plans and the possible postoperative complications of jaw ***,this study aimed to perform a detailed and extended epidemiological analysis of jaw cysts in a large population in West China.

Stem cells remain in a quiescent state for long-term maintenance and preservation of potency;this process requires fine-tuning regulatory *** this study,we identified the epigenetic landscape along the developmental trajectory of skeletal stem cells(SSCs)in skeletogenesis governed by a key regulator,Ptip(also known as Paxip1,Pax interaction with transcription-activation domain protein-1).Our results showed that Ptip is required for maintaining the quiescence and potency of SSCs,and loss of Ptip in type II collagen(Col2)^(+)progenitors causes abnormal activation and differentiation of SSCs,impaired growth plate morphogenesis,and long bone *** also found that Ptip suppressed the glycolysis of SSCs through downregulation of phosphoglycerate kinase 1(Pgk1)by repressing histone H3 lysine 27 acetylation(H3K27ac)at the promoter ***,inhibition of glycolysis improved the function of SSCs despite Ptip *** the best of our knowledge,this is the first study to establish an epigenetic framework based on Ptip,which safeguards skeletal stem cell quiescence and potency through metabolic *** framework is expected to improve SSC-based treatments of bone developmental disorders.

Micro-computed tomography (MCT) encompasses two primary scanning options: ex-vivo and in-vivo imaging. Ex-vivo scanning involves the examination of extracted teeth or dental specimens, allowing for detailed analyses of the microarchitecture of mineralized tissue. By analyzing the microarchitecture of dental tissues, MCT can provide valuable information about bone density, porosity, and microstructural changes, contributing to a better understanding of disease progression and treatment outcomes. Moreover, MCT facilitates the quantification of dental parameters, such as bone volume, trabecular thickness, and connectivity density, which are crucial for evaluating the efficacy of dental interventions. This present study aims to comprehensively review and explore the applications of MCT in dentistry and highlight its potential in advancing research and clinical practice. The results depicted that the quantitative approach of MCT enhances the precision and reliability of dental research. Researchers and clinicians can make evidence-based decisions regarding treatment strategies and patient management, relying on quantifiable data provided by MCT. The applications of MCT in dentistry extend beyond research, with potential clinical implications in fields such as dental implantology and endodontics. MCT is expected to play an increasingly significant role in enhancing our understanding of dental pathologies, improving treatment outcomes, and ultimately, benefiting patient care in the field of dentistry.
