Article Abstract
Background: The question arises if there is an association of psycho-emotional stress and chronic soft tissue injuries caused by bruxism somatoform disorders with oral squamous cell carcinoma (OSCC).
Methods: Patients with and without "somatoform disorders including psychogenic disturbances" (International Classification of Diseases [ICD]-10 code F45.8), and/or "unspecific behavioral syndromes" (F59), and/or "sleep related bruxism" (G47.63), and/or "other sleep disorders" (G47.8) were retrieved from the TriNetX network to gain cohort I. Cohort II was formed by patients without the aforementioned diagnoses, and by matching for age, gender, tobacco use, and alcohol abuse. After defining the primary outcome as "OSCC" (ICD-10 codes C00-C14), a Kaplan-Meier analysis was performed, and risk ratio (RR) and odds ratio (OR) were calculated.
Results: After matching, each cohort accounted for 154,639 patients (59.7% females; 40.3% males; mean current age (± standard deviation) = 43.4 ± 24.5 years). Among cohorts I and II, 907 and 763 patients, respectively, were diagnosed with OSCC within 5 years (risk of OSCC = 0.6% and 0.5%), whereby the risk difference was significant ( < 0.001; Log-Rank test). RR and OR were 1.19 (95% confidence interval (CI), lower = 1.08 and upper = 1.31) and 1.19 (95% CI, 1.08-1.31).
Conclusions: Psycho-emotional stress and/or chronic mucosal injuries may play a role in carcinogenesis. However, the results need to be interpreted cautiously due to limitations of the applied approach. It may thus far only be concluded that further research is necessary to investigate hypotheses regarding psychogenic carcinogenesis and tumor formation due to chronic tissue trauma.

Background: Periodontitis is considered to be one of the major risk factors associated with cancers of the oral cavity. Periodontogenic pathogens such as and are the important pathogens associated with periodontitis. Chronic exposure to bacterial components induces changes in the nearby cells.

Squamous carcinoma of the head and neck is characterized by aberrant apoptosis that prolongs the proliferative capacity of the cells and by uncontrolled cell growth. This study aimed to examine the pro-apoptotic and antiproliferative effects of cassane diterpenoids on squamous carcinoma cells . The cytotoxicity of four (4) cassane diterpenoids {Six-cinnamoyl- 7-hydroxyvouacapen-5-ol(1), pulcherrimin A(2), C(3), and E(4)} isolated from C.

Actinomycosis is an infection caused by and mainly affects cervicofacial areas. In women, other regions, such as the chest, abdomen, and pelvic cavity can involve actinomycosis. Actinomycosis lesions in the oral cavity can cause pain, swelling, induration, pus discharge, and discomfort similar to other benign or malignant pathologies.

Aim: The hypoxic tumor microenvironment (TME) in oral squamous cell carcinoma (OSCC) is primarily regulated by hypoxia-inducible factor-1 alpha (HIF-1α), impacting histone acetylation and methylation, which contribute to drug resistance. Vorinostat, a histone deacetylase inhibitor (HDACi), de-stabilizes HIF-1α, while PX-12, a thioredoxin-1 (Trx-1) inhibitor, prevents HIF-1α accumulation. Combining HDACi with a Trx-1 inhibitor may enhance efficacy and reduce resistance by increasing reactive oxygen species (ROS) in cancer cells.

Oral squamous cell carcinoma (OSCC) is one of the most prevalent malignant tumors in the oral and maxillofacial region. Traditional treatments for OSCC, including surgery, radiotherapy, and chemotherapy, often lead to severe adverse effects. Therefore, the development of safe and effective novel cancer therapies is crucial for achieving synergistic cancer treatment, significantly enhancing patient survival and quality of life.
