NEET MDS Conservative Dentistry Flashcards
55 question-and-answer cards covering Conservative Dentistry as it is examined in NEET MDS. 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the Conservative Dentistry deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
Name the basic categories of hand cutting instruments.
Cutting (chisels, hatchets, hoes, gingival margin trimmers, excavators) and the formula is described by Black's instrument formula (3 or 4 numbers).
What do the numbers in Black's three-number instrument formula represent?
1st = blade width (0.1 mm); 2nd = blade length (mm); 3rd = blade angle relative to the long axis of the handle (centigrades, 1/100 of 360°).
What is the principal advantage of amalgam over composite in posterior teeth?
Superior durability/wear resistance, lower technique sensitivity, lower cost, and better performance in moisture-contaminated or large stress-bearing situations.
What is the total-etch (etch-and-rinse) technique?
Application of 30–40% phosphoric acid to etch enamel and dentin simultaneously, removing the smear layer, followed by primer/adhesive before composite placement.
What is a self-etch adhesive?
An adhesive using acidic monomers that simultaneously etch and prime dentin/enamel without a separate rinse step, incorporating the smear layer.
What is the recommended incremental thickness for light-cured composite and why?
≤2 mm increments to ensure adequate depth of cure and to reduce polymerization shrinkage stress (except for bulk-fill composites).
What is the indication difference among Type I, II, and III GIC?
Type I: luting/cementation; Type II: restorative (esthetic and reinforced); Type III: liners/bases and fissure sealants.
Define inlay and onlay.
An inlay is an indirect intracoronal restoration fitting within cusps; an onlay is an indirect restoration that covers one or more cusps (extracoronal coverage of cusp tips).
When is full-coverage crown indicated over a direct restoration?
For extensively damaged/endodontically treated teeth, large old restorations, cuspal fracture, or when significant strength/protection and esthetics are required.
What is a dental veneer and its two types?
A thin layer of restorative material covering the labial surface for esthetics; types are direct (composite, chairside) and indirect (porcelain/ceramic, lab-fabricated).
What is reversible pulpitis and its hallmark symptom?
Mild, reversible pulpal inflammation; sharp pain to stimuli (cold/sweet) that subsides quickly when the stimulus is removed; pulp recovers if the irritant is removed.
How is irreversible pulpitis distinguished clinically from reversible pulpitis?
Irreversible pulpitis gives spontaneous, lingering pain (lasting after stimulus removal), often worse with heat and on lying down; it requires root canal treatment or extraction.
What differentiates acute apical periodontitis from a periapical abscess?
Apical periodontitis is inflammation of the periodontal ligament at the apex (tender to percussion); a periapical (alveolar) abscess is a localized purulent (pus) collection with swelling.
What are the objectives of root canal treatment?
Thorough cleaning and shaping (chemo-mechanical debridement), disinfection, and three-dimensional obturation of the canal system to prevent reinfection.
What is the most common irrigant in endodontics and its action?
Sodium hypochlorite (NaOCl, 1–5.25%); it dissolves organic/necrotic tissue and is a potent antimicrobial; EDTA is used to remove the inorganic smear layer.
What is the gold-standard core obturating material and its sealer partner?
Gutta-percha as the core material, used with a root canal sealer (e.g., zinc oxide-eugenol, resin, or bioceramic sealer).
How is a 'hot tooth' (acute irreversible pulpitis) emergency managed?
Achieve profound anesthesia (supplemental intraligamentary/intrapulpal), perform pulpotomy or pulpectomy to remove inflamed tissue and relieve pain.
What are the principles/elements of esthetic (smile) design?
Tooth shade/color, shape and proportion (golden proportion), symmetry, midline alignment, incisal edge position, gingival contour/health, and lip framing.
What are the main vital tooth bleaching techniques?
In-office (high-concentration hydrogen peroxide, often light/heat activated) and at-home (low-concentration carbamide peroxide in custom trays).
What active agents are used in tooth bleaching and how do they work?
Hydrogen peroxide and carbamide peroxide; they release free radicals (reactive oxygen) that oxidize and break down chromogenic (stain) molecules in the tooth.
Name Ellis classification classes for crown/tooth fractures (1–3).
Class 1: enamel only fracture; Class 2: enamel + dentin (no pulp exposure); Class 3: enamel + dentin + pulp exposure (Ellis extends to 9 covering root/displacement/avulsion).
What is the emergency management of an avulsed permanent tooth?
Replant immediately if possible; otherwise store in a physiologic medium (HBSS, milk, or saliva) and seek care urgently; later splint and perform endodontic treatment as indicated.
What is the most commonly used laser type in soft-tissue dentistry, and one used for hard tissue?
Diode and Nd:YAG lasers for soft tissue; Erbium lasers (Er:YAG / Er,Cr:YSGG) for hard tissue (caries removal, cavity prep) due to water absorption.
What is regenerative endodontics?
Biologically based procedures to replace damaged pulp-dentin tissue, typically via revascularization in immature necrotic teeth using disinfection, blood clot/scaffold, and a coronal seal to promote continued root development.
What this deck covers
The Conservative Dentistry deck follows the NEET MDS Conservative Dentistry syllabus — 11 chapters and 31 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 5.0 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 158 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.
Conservative Dentistry flashcards FAQ
How many Conservative Dentistry flashcards are in this NEET MDS deck?
55 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these NEET MDS flashcards free?
Yes. The preview here is free to read with no signup, and the full 55-card deck is free inside the Examius app.
What do the Conservative Dentistry cards cover?
They follow the NEET MDS Conservative Dentistry syllabus — 11 chapters and 31 topics — so the questions track what is actually examinable.
How should I use these flashcards?
Read the syllabus first so you know the shape of the subject, then drill the deck. Examius schedules each card with spaced repetition, so cards you keep missing come back sooner and ones you know drift further apart.
