Discuss the causes and pathological features of inflammatory/reactive lesions of the oral cavity.

Inflammatory/reactive lesions of the oral cavity can be caused by various factors such as trauma, infection, or immune system dysfunction. Pathological features may include cellular inflammation, tissue damage, and presence of specific inflammatory cells like neutrophils or lymphocytes. Signup and view all the answers

What are the causes and pathogenesis of precancerous and cancerous oral lesions?

Precancerous oral lesions can be caused by chronic irritation, inflammation, or viral infections, leading to genetic mutations and dysplastic changes. Cancerous oral lesions can arise from accumulated genetic mutations and uncontrolled cell growth. Signup and view all the answers

Discuss the epidemiology, pathogenesis, and morphology of squamous cell carcinoma in the oral cavity.

Squamous cell carcinoma in the oral cavity is commonly associated with tobacco and alcohol use. Pathogenesis involves genetic alterations and dysplastic changes in squamous epithelial cells. Morphologically, it presents as infiltrative nests of malignant squamous cells. Signup and view all the answers

Classify salivary gland non-neoplastic lesions and discuss their characteristics.

Salivary gland non-neoplastic lesions can be classified into categories such as sialadenitis (inflammation of salivary glands), sialosis (non-inflammatory enlargement of salivary glands), and ductal ectasia (dilation of salivary gland ducts). These lesions may present with symptoms of swelling, pain, or dryness in the oral cavity. Signup and view all the answers
