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.

Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Objective: To study the effects of long non-coding RNA linc-01135 on the osteogenic differentiation of inflammatory PDLSCs(P-PDLSCs) under 12％ static mechanical strain loading. Methods: Cells were isolated and cultured from the healthy and periodontitis samples respectively to obtain healthy PDLSCs(H-PDLSCs) and P-PDLSCs. RT-PCR were used to identify the expression level of linc-01135. Lentiviruses were used to upregulate and downregulate the expression of linc-01135, and the osteogenesis gene expression were analyzed by RT-PCR and the osteogenesis differentiation capability were evaluated by alizarin red staining. Results: linc-01135 expression in P-PDLSCs was lower than that in H-PDLSCs. When the expression of linc-01135 was upregulated in P-PDLSCs before 12％ SMS loading, the expression level of RUNX2, ALP, OPG was significantly increased. In contrast, the expression of RUNX2, ALP, OPG was significantly decreased when the expression of linc-01135 was suppressed. Alizarin red staining proved the same trend. Conclusion: linc-01135 can promote the osteogenic differentiation capability of P-PDLSCs under 12％SMS loading.

Objective:To establish the fingerprint analysis method for the root of Rosa laevigata Michx from different regions by UPLC. Methods:The column was ACQUITY UPLC? Phenyl(2.1 mm × 100 mm,1.7 μm). The mobile phase consisted of methanol-water with gradient elution. The flow rate was 0. 2 ml·min-1 , the detection wavelength was 210 nm, the column temperature was 30℃, and the injection volume was 3 μl. Results:The fingerprint consisted of 15 common peaks.

Objective To investigate the relationship between white blood cell count (WBC) and the prevalence of simple fatty liver disease (SFL) and nonalcoholic steatohepatitis (NASH). Methods We designed a large scale cross-sectional study in an adult population. Participants were selected from Tianjin Medical University's General Hospital-Health Management Centre. The diagnoses of simple fatty liver disease and nonalcoholic steatohepatitis were based on liver ultrasonography and serum alanine aminotransferase concentration. A total of 37507 subjects (8644 SFL and 2557 NASH) were included in this study. Multiple logistic regression analysis was used to assess whether the quartiles of WBC were associated with the prevalence of simple fatty liver disease and nonalcoholic steatohepatitis. Results After adjusting for potential confounders, the odds ratios (95% confidence interval) of simple fatty liver disease and nonalcoholic steatohepatitis for increasing quartiles of WBC were: simple fatty liver disease, 1.00 (reference), 1.37 (1.24, 1.50), 1.70 (1.55, 1.86) and 2.09 (1.90, 2.29) (P for trend<0.0001);nonalcoholic steatohepatitis, 1.00 (reference), 1.39 (1.16, 1.66), 1.69 (1.43, 1.99) and 2.13 (1.81, 2.50) (P for trend<0.0001). Conclusions This study proves the correlation between WBC and the prevalence of simple fatty liver disease and nonalcoholic steatohepatitis. Further study is needed to clarify whether WBC has a predictive value for the occurrence of nonalcoholic fatty liver disease.
