Study Notes
Cysts and Tumors
Types of Cysts:
- Dental cysts: develop from dental tissues, e.g. radicular cysts, dentigerous cysts
- Non-dental cysts: develop from non-dental tissues, e.g. nasolabial cysts, thyroglossal cysts
- Pseudo-cysts: do not have an epithelial lining, e.g. mucocele, traumatic bone cyst
Clinical Features of Cysts:
- Painless swelling
- May be asymptomatic
- Can cause bone expansion, displacement of teeth, or resorption of roots
- May be associated with infection or inflammation
Types of Tumors:
- Benign tumors: e.g. fibroma, papilloma, osteoma
- Malignant tumors: e.g. squamous cell carcinoma, melanoma, adenocarcinoma
Clinical Features of Tumors:
- Painful or painless swelling
- Ulceration or bleeding
- May be asymptomatic
- Can cause bone destruction, tooth mobility, or sensory disturbances
Oral Cancer
Definition:
- Malignant neoplasm that develops in the oral cavity, including lips, tongue, floor of the mouth, and palate
Risk Factors:
- Tobacco use (smoking, chewing)
- Alcohol consumption
- Human papillomavirus (HPV) infection
- Poor diet, lack of fruits and vegetables
- Family history
- Previous oral cancer or premalignant lesions
Premalignant Lesions:
- Leukoplakia: white patch or plaque that cannot be scraped off
- Erythroplakia: red patch or plaque that cannot be scraped off
- Dysplasia: abnormal cell growth
Clinical Features of Oral Cancer:
- Non-healing ulcer or sore
- Pain or numbness in the mouth
- Red or white patch or lesion
- Difficulty swallowing or speaking
- Lymph node enlargement
Staging and Treatment:
- Staging: TNM system (tumor size, node involvement, metastasis)
- Treatment: surgery, radiation therapy, chemotherapy, or combination therapy
