Localized juvenile spongiotic gingival hyperplasia(LJSGH)is a kind of gingival hyperplasia with unique pathological manifestations.Its clinical manifestations are atypical,and the etiology and pathogenesis are unclear.No case report was reported in China.The diagnosis of this disease mainly relies on pathological testing,and recurrence may occur after treatment.The best treatment method still lacks medical evidence.This paper reports a case of LJSGH in a teenager and summarizes its clinical,pathological,and treatment through literature review.This work provides a refer-ence for the diagnosis and treatment of this disease.

Risk assessment models for periodontal disease provide dentists with a precise and consolidated evaluation of the prognosis of periodontitis, enabling the formulation of personalized treatment plans. Periodontal risk assessment systems have been widely applied in clinical practice and research. The application fields of periodontal risk assessment systems vary based on the distinctions between clinical periodontal parameters and risk factors. The assessment models listed below are commonly used in clinical practice, including the periodontal risk calculator (PRC), which is an individual-based periodontal risk assessment tool that collects both periodontal and systemic information for prediction; the periodontal assessment tool (PAT), which allows for quantitative differentiation of stages of periodontal disease; the periodontal risk assessment (PRA) and modified periodontal risk assessment (mPRA), which are easy to use; and the classification and regression trees (CART), which assess the periodontal prognosis based on a single affected tooth. Additionally, there are orthodontic-periodontal combined risk assessment systems and implant periapical risk assessment systems tailored for patients needing multidisciplinary treatment. This review focuses on the current application status of periodontal risk assessment systems.

Objective To explore the relationship between serum microRNA-124(miR-124),CD146,angio-poietin-like protein 2(Angptl2)and the stability of carotid atherosclerosis(CAS)plaque in patients with a-cute cerebral infarction(ACI),and to provide reference for early prevention and treatment of patients with ACI.Methods A total of 191 patients with ACI admitted in Handan Central Hospital from January 2020 to February 2023 were selected as ACI group,and another 61 healthy volunteers who were underwent physical examination during the same period were selected as control group.The patients with ACI were divided into unstable plaque group(56 cases),stable plaque group(71 cases),and non plaque group(64 cases)based on carotid color doppler ultrasound results.The serum miR-124 expression levels of all subjects were detected by real time fluorescence quantitative polymerase chain reaction(RT-qPCR),and the serum CD146 and Angptl2 levels were detected by enzyme-linked immunosorbent assay(ELISA).The influencing factors of the instabili-ty of CAS plaque in patients with ACI was analyzed by univariate and multivariate Logistic regression.The predictive value of serum miR-124,CD146 combined with Angptl2 for the instability of CAS plaque in patients with ACI was analyzed by the receiver operating characteristic(ROC)curve.Results The serum CD146 and Angptl2 levels in ACI group were higher than those in control group(P＜0.05),and the miR-124 expression level was lower than that in control group(P＜0.05).Univariate analysis showed that the stability of CAS plaques in ACI patients was correlated with age,hypertension,hyperlipidemia,fibrinogen(FIB),serum C-reac-tive protein(CRP),serum cystatin C(CyC),CD146,Angptl2 and miR-124(P＜0.05).Multivariate Logistic regression analysis showed that the decrease of serum miR-124,the increase of CD146,the increase of Angptl2 and the combination of hyperlipidemia were risk factors for CAS plaque stability in ACI patients(P＜0.05).The area under ROC curve(AUC)of serum miR-124,CD146,Angptl2 and the combination of the three indi-cators to predict CAS plaque instability in ACI patients were 0.741,0.719,0.781 and 0.834,respectively.Conclusion The serum miR-124 expression level,CD146 and Angptl2 levels are the influencing factors of CAS plaque instability in ACI patients,which may be involved in the formation and development of CAS plaque in ACI patients.The combined detection of the three factors has a good predictive effect on CAS plaque instability in ACI patients.
