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.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To exlplore the association between the baseline luteinizing hormone/follicle stimulating hormone (LH/FSH) ratio of polycystic ovary syndrome (PCOS) and in vitro fertilisation-embryo transfer outcomes.Methods:This was a retrospective cohort study. A total of 2 868 PCOS patients were enrolled, all of the participants were patients in The First Affiliated Hospital of Anhui Medical University Hospital from October 2015 to October 2021. Propensity score matching (1∶2.5) was conducted to regulate the non-random allocation of patients. Data were extracted from the hospital′s medical records. Patients with baseline LH/FSH ratio>2 were deemed as study group, patients with baseline LH/FSH ratio≤2 were deemed as control group. Single factor analysis was applied to compare the differences of pregnancy outcomes between two groups.Results:After propensity score matching (1∶2.5), there were no statistically significant differences in baseline data between the two groups (all P>0.05), indicating that the data were comparable. In the study group, the total dose of gonadotropin (Gn) and duration of Gn were lower than those of the control group ( t=4.989, P<0.001; t=3.267, P=0.001), the rate of in vitro maturation was higher than that of the control group ( χ2=4.938, P=0.026), the number of retrieved oocytes and cleavage were higher than those of the control group ( t=-2.305, P=0.021; t=-2.816, P=0.005), but there were no differences in the number and rate of high-quality embryos between the two groups ( t=-1.636, P=0.102; t=-0.123, P=0.902). The incidence of moderate to severe ovarian hyperstimulation syndrome in the study group was significantly higher than that in the control group ( χ2=17.277, P<0.001). Regardless of fresh embryo transfer or frozen-thawed embryo transfer cycles, the incidences of gestational diabetes mellitus in the study group were higher than those in the control group ( χ2=9.174, P=0.002; χ2=4.204, P=0.040) of singleton pregnancy. In the fresh embryo transfer cycle, the clinical pregnancy rate [30.30% (20/66) vs 47.75% (53/111)] and delivery rate [30.30% (20/66) vs 46.85% (52/111)] in the study group were lower than those in the control group ( χ2=5.198, P=0.023; χ2=4.695, P=0.030). In the frozen-thawed embryo transfer cycle, the delivery rate in the study group was higer than that in the control group [59.41% (423/712) vs 55.04% (1 053/1 913); χ2=7.526, P=0.023]. The clinical pregnancy rate and delivery rate of fresh embryo transfer cycle in the study group were significantly lower than those of frozen-thawed embryo transfer cycle ( χ2=21.308, P<0.001; χ2=20.871, P<0.001), but there were no significant differences in the control group (all P>0.05). Conclusions:PCOS patients with a higher basal LH/FSH ratio are more likely to develop moderate to severe ovarian hyperstimulation syndrome after controlled ovarian stimulation and have a higher incidence of gestational diabetes mellitus. Better pregnancy outcome could be obtained by frozen-thawed embryo transfer.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

Objective : To investigate the diagnostic endoplasmic reticulum aminopeptidase-1 (ERAP1) in patients with hepatocellular carcinomae (HCC) ． Methods : Enzyme-linked immunosorbent assay (ELISA) was used to de- tect the serum levels of ERAP1 in HCCpatients，cirrhosis patients and healthy controls (HC) ．Multivariate logistic regression was used to analyze the independent risk factors of the severity and prognosis ，and receiver operating characteristic curve (ROC) was used to evaluatesensitivity and specificity of ERAP1 in the diagnosis of different degree of disease and prognosis. Results : The serum ERAP1 level of HCC was related to tumor stage，tumor size and number of cancer focal (P ＜0. 05 ) ． ERAP1 level of HCC patients was positivecorrelated with ALT ，AST， TBIL and AFP，while negative correlated with ALB(P＜0. 05) ．ERAP1 was found to be an independent predictor of different severity and prognosis．When joint diagnosing HCC with AFP，the area under the curve ( AUC) was 0. 932．For the diagnosis of poor prognosis，the AUC was 0. 742． Conclusion Serum ERAP1 level has important clinical significance and potential application value in evaluating the severity and prognosis of HCC patients.

Objective To explore the prevalence and reference value of disease features of patients with spondyloarthritis. Methods Spondyioarthritis features and laboratory indexes and radiographic indexes of 505 patients with spondyloarthritis (SpA) including 353 patients with ankylosing spondylitis (AS), 62 patients with non-radiographic axial spondyloarthritis (nr-axSpA) and 90 patients with peripheral spondyloarthritis (pSpA) were recorded. One-way analysis of variance, Kruskal-Wallis test, x2-test, Logistic regression were used for statistical analysis. Results Sex ratio ( x2=20.673, P<0.01), age ( x2=22.258, P<0.01), disease duration ( x2=76.052, P<0.01) were different among AS, nr-axSpA and pSpA. Besides, Bath ankylosing spondylitis disease activity index (BASDAI), ankylosing spondylitis disease activity score (ASDAScrp), erythrocyte sedimentation rate (ESR), C-reactionprotein (CRP) and Bath ankylosing spondylitis functional index (BASFI)were different among SpA subgroups ( x2/F=13.196-40.028, P<0.01). Prevalence of inflammatory back pain, peripheral arthritis, preceding infection, positive human lymphocyte antigen (HLA)-B27 and elevated CRP were different among SpA subgroups ( x2=11.416, 32.657, P<0.01). Prevalence of dactylitis in SpA with positive HLA-B27 was lower than that in SpA with negative HLA-B27 ( x2=5.414, P=0.02). Prevalence of enthesitis and dactylitis in SpA patients with peripheral arthritis was higher than that in SpA without peripheral arthritis involvement ( x2=7.177, 14.428, P<0.01). Prevalence of good response to Non-steroid anti-inflammatory drugs. (NSAIDs) in patients with anterior uveitis involvement was higher than SpA without anterior uveitis involvement ( x2=4.578, P=0.032). SpA patients were stratified by total number of SpA features into 4 subgroups (n≤1, n=2, n=3, n≥4). Prevalence of inflammatory back pain, positive HLA-B27, good response to NSAIDs were the top three in all subgroups. Inflammatory back pain and HLA-B27 (+) were risk factors for axSpA (OR=3.254, 3.323, P<0.01). Peripheral arthritis, dactylitis, and preceding infection were risk factors for pSpA (OR=3.759, 4.134, 17.044, P<0.01). Conclusion Inflammatory back pain, HLA-B27 (+) and good response to NSAIDs should be emphasized for the diagnosis of SpA. Inflammatory back pain and HLA-B27(+) always means axSpA. Peripheral arthritis, dactylitis and preceding infection always indicates pSpA.

Objective To explore whether tumor necrosis factor receptor-associated protein 1 (TRAP1)gene copy number variation was associated with susceptibility and clinical characteristics of systemic lupus erythematosus (SLE).Methods The study enrolled 304 SLE patients and 391 healthy controls.They were used to investigate the association between TRAP1 gene copy number variation and SLE susceptibility.Then,304 SLE patients were divided into copy number=2 group and copy number＞2 group to study the association between TRAP1 gene copy number variation and disease activity or clinical characteristics of SLE.AccuCopyTM Kit was used to detect the TRAP1 gene copy number.Data analyses were performed by SPSS 10.01 software.The suitable method was selected among t test,rank sum test and x2 test for analysis based on the data type and distribution,univariate and multivariate logistic regression analysis were performed to investigate the associ-ation between TRAP1 gene copy number variation and susceptibility and clinical characteristics of SLE.Results The copy number variation of TRAP1 gene showed an association with the susceptibility to SLE crude OR=5.257,95％CI (1.108,24.937),P=0.037;the adjusted OR=5.578,95％CI (1.172,26.556),P=0.031].There was no association between TRAP1 gene copy number variation and SLE disease activity index (SLEDAI) score (Z=-0.117,P=0.907).The copy number variation of TRAP1 gene had a marginal association with skin lesions in SLE [OR=0.130,95％CI (0.016,1.069),P=0.058],but it disappeared after adjusting for potential confounders [OR=0.288,95％CI (0.029,2.831),P=0.286,PBH=0.808].There was no correlation between TRAP1 gene copy number variation and arthritis,alopecia,oral ulcers,fever,hematologic disorder,lupus nephritis as well as photosensitivity in SLE [x2=0.751,OR=1.234,95％CI (0.767,1.988),P=0.386].No multiplicative interaction was found between TRAP1 gene copy number variation and age or body mass index (BMI) [age:x2=0.751,OR=1.234,95％CI (0.767,1.988),P=0.386;BMI:x2=0.282,OR=1.172,95％CI(0.652,2.109),P=0.596].Conclusions The copy number variation of TRAP1 gene may be associated with susceptibility to SLE.Increased TRAP1 gene copy number may be a risk factor for SLE.

Objective This study aimed to investigate whether the copy numbers of the CCL3L1 (Chemokine C-C-Motif Ligand 3 Like Protein 1) gene were associated with susceptibility to ankylosing spondylitis (AS). Methods A total of 806 Chinese individuals including 405 AS patients and 401 healthy controls were enrolled. The CCL3L1 gene copy number was measured by a custom-by-design Multiplex AccuCopyTM Kit based on a multiplex fluorescence competitive polymerase chain reaction (PCR) principle, and 50 samples were randomly selected using the fluorescent quantitative PCR method to verify copy number. Main statistical method was t test, chi-square test and logistic regression model. Results There were no statistically significant differences between the case group and control group in age and gender ( t=1.77, P=0.076, χ2=1.14, P=0.289). The copy number of CCL3L1 gene ranged from 0 to 13 in both AS patients and the controls. After copy numbers were classified into 3 categories by 3, we did not find significant difference between the two groups ( χ2=0.591, P=0.669). And regression analyses also did not support the hypothesis that CCL3L1 gene copy number variation (CNV) could be an impact factor to the severity or function indexes of AS patients ( χ2=0.341, P=0.804 and χ2=0.472, P=0.774, respectively). Conclusion We suggest that the copy number of the CCL3L1 gene does not have a role in the susceptibility and the severity or function to AS.
