4. According to the ICDAS (International Caries Detection and Assessment System) , an initial enamel lesion (code 2) is best managed by: A) Surgical excavation and composite restoration B) Non-invasive treatment (fluoride, sealant, resin infiltration) C) Conventional GIC restoration D) Indirect pulp capping
Answer: B
Explanation: ICDAS code 2 = white or brown spot lesion with intact surface (non-cavitated). Non-invasive or micro-invasive (resin infiltration) is indicated.
5. The Hall Technique (preformed metal crowns over carious primary molars without caries removal or LA) relies on: A) Complete caries removal prior to crown cementation B) Sealing the caries from the oral environment C) Antibiotic properties of the crown material D) High fluoride release from the cement
Answer: B
Explanation: The Hall Technique works by sealing carious dentin, starving bacteria of substrate. No caries removal, no LA, no tooth preparation is done. operative+dentistry+mcqs+pdf+new
6. Which bioactive material is specifically indicated for partial caries removal (selective removal to firm dentin) in deep lesions? A) Zinc phosphate cement B) Biodentine™ C) Amalgam D) Polymethyl methacrylate (PMMA)
Answer: B
Explanation: Biodentine (tricalcium silicate-based) has bioactivity, induces tertiary dentin, and is used for deep lesions after selective caries removal to avoid pulp exposure.
