Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Instrument separation is a critical complication during root canal therapy, impacting treatment success and long-term tooth preservation. The etiology of instrument separation is multifactorial, involving the intricate anatomy of the root canal system, instrument-related factors, and instrumentation techniques. Instrument separation can hinder thorough cleaning, shaping, and obturation of the root canal, posing challenges to successful treatment outcomes. Although retrieval of separated instrument is often feasible, it carries risks including perforation, excessive removal of tooth structure and root fractures. Effective management of separated instruments requires a comprehensive understanding of the contributing factors, meticulous preoperative assessment, and precise evaluation of the retrieval difficulty. The application of appropriate retrieval techniques is essential to minimize complications and optimize clinical outcomes. The current manuscript provides a framework for understanding the causes, risk factors, and clinical management principles of instrument separation. By integrating effective strategies, endodontists can enhance decision-making, improve endodontic treatment success and ensure the preservation of natural dentition.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

This case involves a 53-year-old female patient who underwent mechanical mitral valve replacement and has been on long-term warfarin anticoagulant therapy,subsequently developed diffuse ecchymoses of the limbs and progressive both lower extremities swelling after she self-adjusted her warfarin dosage from 3 mg to 6 mg daily over 5 consecutive days.After admission,the patient's international normalized ratio was 12.71,and creatine kinase level was 1,989.47 U·L-1,which led to the diagnosis of coagulopathy and rhabdomyolysis due to warfarin overdose.Following discontinuation of warfarin and initiation of fluid resuscitation therapy,the patient's creatine kinase levels returned to normal after 6 d.Thiscase underscores the necessity of refining long-term warfarin management strategies and enhancing patient education to improve medication adherence and ensure both the efficacy and safety of anticoagulation therapy.

Objective:To construct a predictive model based on preoperative heat shock protein 90 alpha (HSP90 alpha) and lymphocyte count/monocyte ratio (LMR), for prediction of the textbook outcome (TO) of intrahepatic cholangiocarcinoma after surgery, and evaluate the predictive value of the model.Methods:Retrospective analysis of data from 210 patients with intrahepatic cholangiocarcinoma admitted to Chengde Central Hospital from January 2022 to December 2023, including 122 males and 88 females, aged (61.3±5.5) years. The patients were randomly divided into a training set (147 cases) and a validation set (63 cases) according to a ratio of 7: 3. According to whether the patients achieved TO after surgery, the patients in the training set were divided into a TO group ( n=39) and a non-TO group ( n=108). The conditions of tumor length < 5 cm, lymph node metastasis, large vessel invasion, preoperative HSP90α decrease, and preoperative LMR increase were compared between the two groups. Based on the training set, univariate and multivariate logistic regression were used to analyze the influencing factors of postoperative TO in patients with intrahepatic cholangiocarcinoma. Based on multi-factor results, R 4.3.0 software was used to construct a prediction model for TO. The model was evaluated by receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DSA). Results:Multivariate logistic regression analysis showed that the tumor diameter < 5 cm ( OR=1.917, 95% CI: 1.104-4.024), no lymph node metastasis ( OR=2.489, 95% CI: 1.030-3.619), and no invasion of large vessels ( OR=2.565, 95% CI: 2.097-5.093), the decrease of HSP90α before surgery ( OR=3.161, 95% CI: 2.536-5.358), and the increase of LMR before surgery ( OR=2.088, 95% CI: 1.454-4.262) were the influencing factors for patients TO achieve postoperative TO (all P<0.05). A correlation nomogram model was built based on the above indicators. The area under the curve of the model predicting the postoperative TO of the patients in the training set and the test set were 0.875 (95% CI: 0.782-0.938) and 0.860 (95% CI: 0.767-0.912), respectively, indicating good predictive value of the model. The calibration curve was basically consistent with the standard curve, indicating that the model has good consistency and accuracy. DCA results showed that the models had good clinical net benefit in the threshold probability range of 0.1~0.8. Conclusion:The nomogram model based on perioperative HSP90α and LMR has good accuracy and clinical applicability in predicting the possibility of achieving TO after surgery for cholangiocarcinoma, which can provide a reference for clinical treatment.
