When a patient asks about management of medication-induced xerostomia, discussing sugar-free gum, saliva substitutes, water sipping, and pilocarpine respects which ethical principle?

Providing the patient with all reasonable options so they can make an informed decision respects AUTONOMY — the principle that patients have the right to self-determination. Beneficence is acting in the patient's best interest; veracity is truthfulness; justice is fairness in distribution of resources.High-Yield Drug Mechanism ReferenceDrug / Class Mechanism of Action Key Dental Relevance Omeprazole Proton pump inhibitor (PPI) GERD management; associated with enamel erosion from chronic reflux Ranitidine / Famotidine H2-receptor antagonist Reduces gastric acid; oral dryness possible Albuterol / Salmeterol ╬▓2-agonist (bronchodilator) Oropharyngeal candidiasis (rinse mouth after use); xerostomia Atenolol / Metoprolol ╬▓1-selective blocker Decreases cardiac output and heart rate; limit epinephrine to 0.04 mg Candesartan / Losartan Angiotensin II receptor blocker (ARB) Hypertension; minimal oral side effects Lisinopril / Enalapril ACE inhibitor Dry cough, angioedema, dysgeusia Nitroglycerin Ôåæ cGMP via guanylate cyclase ÔåÆ vasodilation Patient should bring OWN nitrate for in-chair angina Aspirin / Clopidogrel Antiplatelet (COX inhibition / P2Y12 inhibition) Prolonged bleeding; do NOT stop without physician clearance Rivaroxaban / Apixaban Direct factor Xa inhibitor Bleeding risk; no routine INR monitoring Warfarin Vitamin K antagonist Check INR < 3.5 before surgical procedures Buspirone Non-benzodiazepine anxiolytic (5-HT1A partial agonist) Chronic anxiety without sedation; no abuse potential Benzodiazepines (diazepam, midazolam, lorazepam) GABA-A receptor positive allosteric modulator Anterograde amnesia, sedation; reverse with flumazenil Carbamazepine Voltage-gated NaÔü║ channel blocker First-line for trigeminal neuralgia Phenytoin NaÔü║ channel blocker (anticonvulsant) Gingival overgrowth (enlargement) Cyclobenzaprine Centrally acting muscle relaxant (structurally similar to TCAs) Short-term use for myofascial / TMD pain Naloxone ╬╝-opioid receptor antagonist Reverses opioid overdose Flumazenil Benzodiazepine receptor antagonist Reverses BDZ oversedation Humira (Adalimumab) Anti-TNF-╬▒ monoclonal antibody Immunosuppression; manage dental infections aggressively Denosumab (Prolia / Xgeva) Anti-RANKL monoclonal antibody MRONJ risk with extractions/implants Bisphosphonates (alendronate, zoledronate) Inhibit osteoclast-mediated bone resorption MRONJ risk; IV forms higher risk than oral Dexamethasone / Prednisone Glucocorticoid Adrenal suppression; consider steroid coverage for surgery Clotrimazole Imidazole — inhibits ergosterol (14-╬▒ demethylase) Topical antifungal for oral candidiasis Nystatin Binds ergosterol ÔåÆ membrane pore formation Topical antifungal; not absorbed systemically Acyclovir / Famciclovir / Valacyclovir Nucleoside analog — inhibits viral DNA polymerase Herpes labialis, primary herpetic gingivostomatitis Pilocarpine / Cevimeline Muscarinic cholinergic agonist Xerostomia (Sj├gren, post-radiation)High-Yield Oral Pathology Quick ReferenceLesion Key Features Management / Clue Parulis (gum boil) Sinus tract from necrotic pulp or deep perio abscess Trace with gutta-percha;

tobacco/coffee/antibiotic use Improved OHI, tongue scraper; essential oils Denture Stomatitis Erythema on palate under denture; Candida albicans Denture hygiene + nystatin/clotrimazole; refer to prosthodontist Antral Pseudocyst Dome-shaped radiopacity on floor of maxillary sinus Incidental finding; no treatment unless symptomatic Odontogenic Keratocyst (OKC) Posterior mandible radiolucency; think Gorlin if multiple Enucleation with Carnoy's solution; peripheral ostectomy Dentinogenesis Imperfecta Gray/blue opalescent teeth; bulbous crowns; pulp obliteration Full-coverage crowns; genetic counseling (AD) Regional Odontodysplasia "Ghost teeth" — thin enamel/dentin, large pulp chambers Usually extract; prosthetic rehabilitation Cleidocranial Dysplasia Hypoplastic clavicles, frontal bossing, supernumerary teeth Multidisciplinary orthodontic/surgical care Gorlin Syndrome (NBCCS) Multiple OKCs, BCCs, bifid ribs, calcified falx cerebri PTCH1 gene;

eye protection Vertical Root Fracture Narrow isolated deep pocket; J-shape radiolucency Extraction (poor prognosis)High-Yield Pearls SummaryASA 1 = healthy; ASA 2 = mild systemic disease (controlled HTN/DM); ASA 3 = severe systemic disease (BP ÔëÑ 140/90 uncontrolled, BMI 40, uncontrolled DM); ASA 4 = life-threatening; ASA 5 = moribund.Normal <120/80; Elevated 120–129/<80; Stage 1 130–139/80–89; Stage 2 ÔëÑ140/90. BP 145/92 = Stage 2.0.04 mg (Ôëê 2 cartridges of 1:100,000 lidocaine with epi) for ASA 3–4 cardiac / hyperthyroid / ╬▓-blocker patients.Potential hypertensive crisis — use minimal epinephrine or plain LA.Prosthetic valves, previous IE, certain CHD, cardiac transplant with valvulopathy. Mitral valve prolapse WITHOUT regurgitation does NOT require prophylaxis.Excisional if <1 cm & benign-appearing; incisional if large, suspicious, or ulcerated; cytologic for wipeable/superficial lesions."Complicated" = pulp exposure. Uncomplicated = enamel/dentin only (no pulp).ÔëÑ 1.5–2 mm of sound tooth structure 360° is the single most important factor for post-core-crown longevity.In lateral excursions, only the canine contacts on the working side; all other teeth disocclude.The lateral pterygoid protrudes the mandible and deviates to the OPPOSITE side — deviation on opening indicates weakness on the SAME side as the deviation.Angina ÔåÆ patient's own nitroglycerin SL. Opioid overdose ÔåÆ naloxone. BDZ overdose ÔåÆ flumazenil. Hypoglycemia ÔåÆ oral glucose / IM glucagon.Bell's = entire hemi-face (forehead involved). Stroke = forehead spared (dual UMN innervation).Higher with IV bisphosphonates, denosumab, long duration, and steroids. Invasive dental work pre-therapy; conservative care during therapy.Failure of fusion of maxillary + medial nasal processes (lip) and palatal shelves (palate). Associated risk factors: maternal smoking, alcohol, folate deficiency, anti-epileptics.Autonomy (self-determination), Beneficence (do good), Non-maleficence (do no harm), Justice (fairness), plus Veracity (truthfulness) and Fidelity (keep promises).Protected Health Information cannot be shared without the patient's explicit authorization — not even with a spouse — except for treatment, payment, and operations (TPO).
