Background/purpose: The diagnosis and treatment of Sjogren's syndrome (SS) are commonly conducted by rheumatologists and stomatologists. The purpose of this study was to compare the scientometric characteristics of SS publications by rheumatologists and stomatologists.

Materials And Methods: All the papers on cheilitis were comprehensively retrieved from the Scopus database, and divided into rheumatologists and stomatologists groups.

Background: Head and neck osteosarcoma (HNOS) is the most common bone malignancy in the head and neck region, accounting for 10% of all osteosarcoma cases. Perineural invasion (PNI) is a notable indication of aggressive tumor behavior, which includes the phenomenon of tumor cells invading any of the 3 layers of the nerve sheath or tumor cells gathering, encircling one-third of the nerve circumference, and infiltrating and metastasizing along the nerve. PNI has been reported in various malignant tumors and is considered to be linked to poor prognosis.

In 2020, Fanconi anemia (FA) was classified as a syndrome with insufficient epidemiological evidence in the oral potentially malignant disorder (OPMD) group by the WHO Collaborating Centre. The paucity of case reports on FA-associated OPMD limits evidence-based management, and such cases have not been analyzed collectively in detail. Hence, the objective of this short communication is to summarize the evidence on the onset and progression of OPMD in FA patients, so as to better understand the natural history of oral cancer development in patients affected by FA.

Introduction: A prospective observational study was modified to assess the efficacy of surgery alone for the treatment of locally advanced oral squamous cell carcinoma.

(la-oscc) Materials And Methods: This prospective, single-institution, single-arm study involved 174 patients who underwent major surgery for LA-OSCC. Participating patients did not receive postoperative radiation.

Tumor progression is closely related to tumor tissue metabolism and reshaping of the microenvironment. Oral squamous cell carcinoma (OSCC), a representative hypoxic tumor, has a heterogeneous internal metabolic environment. To clarify the relationship between different metabolic regions and the tumor immune microenvironment (TME) in OSCC, Single cell (SC) and spatial transcriptomics (ST) sequencing of OSCC tissues were performed.

This research focuses on investigating the changes of oral flora, inflammatory factors, and immune function indicators in patients with chronic periodontitis (CP) and their clinical significances. Clinical indices such as gingival index (GI) and sulcus bleeding index (SBI) of the study subjects were recorded. The levels of oral flora, inflammatory factors and T lymphocyte subsets in gingival crevicular fluid (GCF) of the study subjects were measured.

Purpose: Oral squamous cell carcinomas (OSCCs) are primary head and neck malignant tumours with a high incidence and mortality. However, the molecular mechanisms involved in OSCC tumorigenesis are not fully understood.

Methods: OSCC and paired para-carcinoma samples were collected and used to perform multi-omics study.

Background: The basicranial region lacks definite boundaries and includes various anatomical units. We developed a novel concept of the posterior oral anatomical complex (POAC) to identify these anatomical units in the basicranial region. OSCC with POAC involvement is termed posterior oral squamous cell carcinoma (POSCC) with poor prognosis.

Background: Head and neck dermatofibrosarcoma protuberans (HNDFSP) is extremely rare and not entirely understood.

Objective: To investigate the clinicopathological features of HNDFSP and identify the expression of its clinically relevant indicators, with the expectation of improving the existing treatment strategies.

Methods: A long-term follow-up of patients with HNDFSP who received treatment between 2000 and 2021 at Shanghai Ninth People's Hospital was conducted.

Objective: Unicystic ameloblastomas are a variant of ameloblastoma with a definite recurrence rate because of the biological behaviours of the tumour. The risk factors associated with disease recurrence were analysed in this retrospective study.

Methods: A total of 132 patients with primary unicystic ameloblastoma reported in a tertiary hospital from 2005 to 2015 were analysed to identify the clinic-pathological and radiological factors associated with recurrence using univariate and multivariate Cox regression analyses.

Background: Some head and neck cancer surgeons found that many patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) without postoperative radiotherapy (PORT) also have a good prognosis. The purpose of this study was to determine the effect of PORT on survival in patients with LA-HNSCC.

Methods: A case-match cohort analysis was performed at two institutions on patients with LA-HNSCC.

Oral squamous cell carcinoma (OSCC) is the most common type of oral malignancy, and metastasis accounts for the poor prognosis of OSCC. Autophagy is considered to facilitate OSCC development by mitigating various cellular stresses; nevertheless, the mechanisms of autophagy in OSCC cell proliferation and metastasis remain unknown. In our study, high-sensitivity label-free quantitative proteomics analysis revealed nuclear protein 1 (NUPR1) as the most significantly upregulated protein in formalin-fixed paraffin-embedded tumour samples derived from OSCC patients with or without lymphatic metastasis.

Purpose: To obtain the relative volume by measuring the tongue volume and the lesion volume, and further explore its relationship with the prognosis of patients, hoping to supplement the TNM staging with a new index.

Methods: ITK-SANP software was used to outline the patients' MRI. After MRI reconstruction and measurement, slicer software was used to estimate tumor volume.

Background: To evaluate the prevalence and incidence of periodontitis and associated disability-adjusted life years (DALYs) from 1990 to 2019.

Methods: We collected data on periodontitis between 1990 and 2019 from the Global Burden of Disease (GBD) 2019 Study. The global prevalence, incidence, and DALYs attributed to periodontitis were analyzed.

Background: Bone homeostasis is mediated by osteoblast-related bone formation and osteoclast-related resorption. The imbalance of bone homeostasis due to excessive osteoclastogenesis or reduced osteogenesis can result in various disorders, such as postmenopausal osteoporosis (PMOP). The receptor activator of nuclear factor-κB ligand (RANKL)-induced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and mitogen-activated protein kinase (MAPK) pathways are essential in osteoclastogenesis.

Background: The aim of this study is to estimate the incidence, mortality, and disability-adjusted life years (DALYs) of nasopharyngeal carcinoma from 1990 to 2017.

Methods: We collected detailed information on nasopharyngeal carcinoma from 1990 to 2017 based on data from Global Burden of Disease (GBD) study 2017. The global incidence, mortality, and DALYs attributable to nasopharyngeal carcinoma was reported, as well as the age-standardized rates (ASRs).

Backgroud: Diabetes mellitus is a common chronic disease and a severe public health issue. The incidence trends for type 1 diabetes (TIDM) and type 2 diabetes (T2DM) have rarely been studied on a global scale. We aimed to determine the temporal and geographical trends of diabetes globally.

Background: Late diagnosis of a salivary fistula increases the risk of wound infection and scarring. The purpose of the present study was to identify a quantitative predictor of postoperative salivary fistula for cases treated with surgery.

Methods: Demographic, intraoperative and postoperative parameters for 57 cases that received surgery for benign parotid tumours were recorded from June 2017 to June 2018, of which 18 cases developed salivary fistulas.
