For a chairside CAD/CAM restoration (e.g., CEREC), the most appropriate cement for a feldspathic ceramic or leucite-reinforced glass-ceramic is: A) Zinc phosphate B) Self-adhesive resin cement (universal) C) Glass ionomer cement D) Polycarboxylate cement
A patient presents with a deep carious lesion on tooth #19. Radiographs show proximity to the pulp but no periapical pathology. The tooth responds normally to vitality testing. During excavation, a pinpoint exposure (
💡 An axial depth of 2.5 mm significantly penetrates the dentin layer. As remaining dentin thickness (RDT) drops below 1.5 to 2.0 mm, pulpal response and the risk of thermal/bacterial inflammation increase exponentially. Maintaining maximum RDT is the single most critical factor in protecting the pulp during operative procedures.

Many universities offer retired examination papers in format. For example, the BDS Final Professional Examination model paper provides authentic question patterns spanning hand cutting instruments, water spray advantages, GV Black’s conclusions, senile carious lesions, high copper amalgam alloys, cavosurface margins, pin depths, diamond burs, and Class III restorations. These are particularly useful for understanding local board exam patterns.
Hand cutting instruments consist of a handle, shank, and blade. 🔍 Preparation Strategies
Ensure the questions reflect the latest editions of major textbooks (e.g., Sturdevant’s 7th or 8th editions) to avoid learning outdated techniques. For a chairside CAD/CAM restoration (e

While studying, don’t forget the basics of patient education that often pop up in "easy" MCQ sections. The 2-2-2 Rule —brushing twice daily for two minutes and seeing a dentist twice a year—is a classic public health question that every clinician should know. During excavation, a pinpoint exposure ( 💡 An
