Study Notes
Maxillary Sinus Functions
- Functions include making the cranium lighter, acting as a resonant bone, and regulating inspired air temperature for drainage.
Hypoadrenalism (Cushing's Syndrome)
- Features include moon face, buffalo hump, skin hyperpigmentation, hypertension, and diabetes mellitus. Hirsutism and purple stretch marks are not typical.
Hyperthyroidism
- Signs encompass nervousness, irritability, tremors, excessive sweating, warm moist skin, and exophthalmos.
Dental Abscess Treatment
- Clindamycin is the preferred antibiotic for patients with liver failure and dental abscesses.
Local Anesthetic Solutions
- Vasoconstrictors in local anesthetics reduce toxicity and prolong duration, while incorrectly increasing bleeding and toxicity.
Inferior Alveolar Nerve Block
- The needle should ideally pass posterior and medial to the medial pterygoid during the block.
Local Anesthetic Allergy
- Clinical presentations may include rash, laryngeal edema, bronchospasm, and urticaria.
Non-Myelinated vs. Myelinated Axons
- Non-myelinated axons lack nodes of Ranvier, are more excitable, and differ in regenerative capabilities.
Anesthesia Techniques
- Field blocks require injection near large branches of peripheral nerves.
- The most challenging tooth for infiltration anesthesia is the maxillary first molar.
Oroantral Fistula Management
- Persistent fistulas post-extraction may require surgical closure after 12 weeks.
Posterior Superior Alveolar Nerve
- Supplies maxillary second and third molars, and first molar (except mesio-buccal root of the maxillary first molar).
Side Effects of Local Anesthesia
- To minimize side effects, techniques should include aspiration, using minimal effective volumes, and avoiding rapid injections.
True/False Statements
- Controlled hypothyroidism allows for safe extractions. The lingual nerve innervates the lingual gingiva and floor of the mouth. Lidocaine duration is not one to two days. Sialography does not test thyroid function. Glucose levels of 6.5 mmol/dl signal prediabetes. Penicillin is bactericidal, not bacteriostatic. SYNACTHEN test aids in diagnosing Addison's disease. Stenson's duct is located near the upper second molar. Vasoconstrictors can exacerbate bleeding during extractions. Maxillary sinusitis often involves aerobic bacteria. Severe periodontitis is associated with diabetes. Individuals on steroids should receive hydrocortisone before extractions. The thyroid gland regulates other endocrine functions. Lidocaine is an amide anesthetic. Palatal infiltration is painful due to tight mucoperiosteum. Mild systemic diseases correspond to ASA class II, not class IV. Thyroid hormones affect tissue sensitivity to catecholamines. Complications of diabetes include various comas. Ethmoidal sinuses are not the largest; maxillary sinuses are. Post-extraction complications may indicate an oro-antral fistula.
