NEET MDS 2026: MERITERS PREDICTIONS | General Medicine - 15 MOST LIKELY Question Topics
The Philosophy
"General Medicine for dental exams is entirely about dental implications. They don't test you like a physician; they test you on how a systemic disease alters your treatment plan or puts the patient at risk in your chair."
A targeted breakdown of the highest priority topics based on recent question patterns and examiner logic.
1. Cardiovascular: Infective Endocarditis (IE)
High PriorityCore Focus
- Organisms: S. viridans (subacute, post-dental extraction), S. aureus (acute, IV drug users)
- AHA Guidelines: Prophylaxis required for prosthetic valves, previous IE, congenital heart disease
- Clinical signs: Osler's nodes (painful), Janeway lesions (painless), Roth spots
NEET MDS LOGIC
The highest yield topic in Medicine for dentists. You absolutely must know the American Heart Association (AHA) prophylaxis guidelines. MVP (Mitral Valve Prolapse) no longer requires prophylaxis unless there's a history of IE.
Framing: "Which of the following cardiac conditions mandates antibiotic prophylaxis prior to a tooth extraction?"
Past Question Patterns
- NEET MDS 2025: Most common organism causing subacute infective endocarditis after dental procedures.
- NEET MDS 2023: Condition requiring AHA endocarditis prophylaxis.
- NEET MDS 2021: Painful, erythematous nodules on the pads of fingers and toes in IE are called.
- INI-CET 2022: Antibiotic of choice for IE prophylaxis in a penicillin-allergic patient.
2. Cardiovascular: Ischemic Heart Disease & MI
Core Focus
- Stable vs Unstable Angina vs Myocardial Infarction
- Biomarkers: Troponin I and T (most sensitive/specific, peak at 24h), CK-MB
- ECG Changes: ST elevation (STEMI), T-wave inversion, pathological Q waves
NEET MDS LOGIC
Time is muscle. You must know how to diagnose an MI in the dental chair (unrelieved by nitroglycerin) and the specific cardiac markers used in the ER to confirm it.
Framing: "A patient experiences severe chest pain in the dental chair that is not relieved by 3 doses of sublingual nitroglycerin. The most specific serum biomarker for diagnosing an acute myocardial infarction is?"
Past Question Patterns
- NEET MDS 2024: Most specific and sensitive biomarker for acute myocardial infarction.
- NEET MDS 2022: ECG finding indicative of an acute full-thickness myocardial infarction.

3. Endocrinology: Diabetes Mellitus
Core Focus
- Diagnostic criteria: Fasting >126 mg/dL, Random >200 mg/dL, HbA1c >6.5%
- Complications: DKA (Type 1, ketones, Kussmaul breathing) vs HONK (Type 2)
- Dental implications: Delayed healing, severe periodontitis, morning appointments preferred
NEET MDS LOGIC
Diabetes intersects heavily with periodontology. HbA1c is heavily tested as it shows a 3-month average of blood glucose (life span of RBCs). Managing hypoglycemia in the dental chair is a critical skill.
Framing: "Which laboratory test provides the most accurate reflection of a patient's glycemic control over the preceding 2 to 3 months?"
Past Question Patterns

- Thyroid Storm: Life-threatening hyperthyroid crisis, triggered by stress/infection
NEET MDS LOGIC
The TSH feedback loop is the core concept. In primary hyperthyroidism, the thyroid goes rogue, making too much T3/T4, which suppresses TSH to near zero. Epinephrine should be used with extreme caution in hyperthyroid patients.
Framing: "A patient presents with weight loss, tachycardia, exophthalmos, and a fine tremor. Laboratory investigations are most likely to show?"
Past Question Patterns
- NEET MDS 2024: Lab profile of primary hyperthyroidism.

- Addison's Disease: Primary adrenal insufficiency, hyperpigmentation of oral mucosa
- Acute Adrenal Crisis: Triggered by stress in patients on long-term steroids (Rule of Twos)
NEET MDS LOGIC
Addison's causes oral pigmentation due to lack of cortisol negative feedback, leading to high ACTH and MSH. Patients on chronic steroids cannot mount a stress response and may crash (Adrenal Crisis) during surgery without steroid cover.
Framing: "A patient on long-term systemic corticosteroid therapy is scheduled for a surgical extraction. To prevent an acute adrenal crisis, the dentist should?"
Past Question Patterns
- NEET MDS 2023: Reason for oral mucosal hyperpigmentation in Addison's disease.

- Von Willebrand Disease: Defect in vWF, prolonged Bleeding Time (BT) AND prolonged aPTT
- Warfarin monitoring: PT/INR (Target 2.0 - 3.0 for extractions)
NEET MDS LOGIC
You MUST know your pathways. Intrinsic pathway = aPTT (Hemophilia). Extrinsic pathway = PT (Warfarin/Liver disease). Platelet defects = Bleeding Time (vWD).
Framing: "A male patient presents with spontaneous hemarthrosis and prolonged bleeding after a dental extraction. Lab tests show a normal PT, normal bleeding time, but a significantly prolonged aPTT. The most likely diagnosis is?"
Past Question Patterns

- Bell's Palsy: Idiopathic LMN lesion of CN VII, unilateral total facial paralysis
- Horner's Syndrome: Ptosis, Miosis, Anhidrosis (Sympathetic chain disruption)
NEET MDS LOGIC
Diagnostic differentiation. If a patient can wrinkle their forehead, it's a central (UMN) stroke. If the whole half of the face is paralyzed (forehead included), it's peripheral Bell's palsy (LMN).
Framing: "A patient presents with sudden onset unilateral facial paralysis, inability to close the eye on the affected side, and loss of taste on the anterior two-thirds of the tongue. The most likely diagnosis is?"
Past Question Patterns

12. Gastroenterology: Peptic Ulcer & GERD
Core Focus
- Peptic Ulcer Disease (PUD): H. pylori infection (most common), Cause - NSAIDs
- Gastric vs Duodenal: Duodenal ulcer pain is RELIEVED by food; Gastric is WORSENED by food
- GERD: Acid reflux, risk of Barrett's esophagus (metaplasia -> adenocarcinoma), dental erosion
NEET MDS LOGIC
GERD causes severe lingual erosion of maxillary teeth. H. pylori is treated with Triple Therapy (PPI + Clarithromycin + Amoxicillin). NSAIDs inhibit COX-1, reducing protective gastric prostaglandins.

- Hepatitis C: RNA virus, high rate of chronic infection and cirrhosis, bloodborne
- Cirrhosis: Portal hypertension, esophageal varices, impaired coagulation factor synthesis
NEET MDS LOGIC
Liver disease equals bleeding risk (decreased synthesis of all clotting factors except VIII). Hep B serology is heavily tested: Anti-HBs is the ONLY marker positive if the patient has been vaccinated successfully.
Framing: "A healthcare worker is screened for Hepatitis B. Their lab results show negative HBsAg, negative Anti-HBc, and positive Anti-HBs. This profile indicates?"
Past Question Patterns
- NEET MDS 2025: Serological profile indicating immunity to Hepatitis B solely due to vaccination.

- Renal Osteodystrophy: Secondary hyperparathyroidism due to failure to activate Vitamin D
- Dental implications: Schedule dental treatment the day AFTER hemodialysis (heparin effect)
NEET MDS LOGIC
Timing of treatment is the core dental question. Never extract teeth on the day of dialysis because the patient is fully heparinized. The kidney activates Vitamin D; failing kidneys lead to low Calcium, which triggers high PTH (Secondary Hyperparathyroidism).
Framing: "To minimize the risk of severe bleeding, elective dental extractions for a patient undergoing hemodialysis should ideally be scheduled?"
Past Question Patterns
- NEET MDS 2024: Ideal timing for dental treatment in a hemodialysis patient.
- NEET MDS 2022: Primary cause of secondary hyperparathyroidism in Chronic Kidney Disease.

- Syphilis: Treponema pallidum, Primary (Painless chancre), Secondary (Maculopapular rash, condyloma lata)
- Diagnostics: VDRL (Screening, non-specific), FTA-ABS (Confirmatory, highly specific)
NEET MDS LOGIC
Know the specific Treponemal vs Non-Treponemal tests. VDRL is used to monitor treatment success (levels drop). FTA-ABS remains positive for life. In HIV, the exact CD4 threshold for AIDS is 200 cells/mm³.
Framing: "Which of the following serological tests is highly specific and used to confirm a diagnosis of Syphilis, remaining positive for the patient's lifetime?"
Past Question Patterns
- NEET MDS 2025: Confirmatory test for Syphilis.
- NEET MDS 2023: CD4 count threshold defining the transition from HIV to clinical AIDS.
- NEET MDS 2021: Painless, indurated ulcer at the site of inoculation is characteristic of.
- INI-CET 2022: Most common oral opportunistic infection in HIV-positive individuals.
Topper Logic
Always connect the systemic disease to the Lab Value. If it's Hemophilia, look for a prolonged aPTT. If it's Warfarin therapy, check the PT/INR. If it's Diabetes, look at the HbA1c. The exam questions revolve around interpreting these critical numbers.
