Sample NEET MDS Clinical Questions – Dental Material Sciences

Free NEET MDS clinical questions

Most students studying for the NEET MDS exam make the ultimate mistake of waiting too long into their study period until they decide to practice Clinical NEET MDS MCQs. Other aspirants fear the MCQs and avoid solving sample NEET MDS Questions altogether. This practice of not solving the questions can hold back your Dental PG exam score.

If you want to establish a baseline early into your NEET MDS preparation and want to track your improvement throughout the process, then you must assess your weaknesses and strengths. This would help you to personalize your studies. PULP offers you free ten clinical NEET MDS MCQs from the Dental Material Sciences topic to gauge where you stand in your prep.

Q 1. A 26-year-old man returns 1 week after having a deep amalgam restoration in his lower right first molar (LR6). The patient experienced shooting pain that lasted for a few seconds when drinking cold drinks. The restoration was removed by an emergency dentist and replaced with zinc oxide eugenol (ZOE). What is the primary benefit of using this material in this situation?
A. Antimicrobial
B. Less microleakage
C. Fast setting
D. High compressive strength
E. Obtundent

Q 2. A 56-year-old man attends for construction of an upper partial cobalt-chromium (CoCr) denture. He has previously struggled to tolerate a full palatal coverage acrylic denture because of his gag reflex. The patient is a chemical engineer by trade and wishes to know what property of CoCr allows provision of a thinner and less extensive major connector. Which single property of CoCr can facilitate this design?
A. Good corrosion resistance
B. High fatigue resistance
C. High yield strength
D. Low mobility
E. Low thermal resistance

Q 3. A 46-year-old man has had four permanent lower molars prepared for gold onlays to manage his generalized moderate toothwear. The preparations have minimal retention or resistance form. What single material is the most appropriate for cementation?
A.Glass-ionomer cement
B. Polycarboxylate cement
C. Resin cement
D.Resin-modified glass-ionomer cement
E. Zinc phosphate

Q 4. A 64-year-old woman is having a new upper complete denture made. She has a hypermobile or ‘flabby’ anterior ridge, and a window technique is planned for the master impression. What primary property is desired of the impression material used in the flabby area?
A. Dimensionally stable
B. High elasticity
C. High viscosity
D. Low elasticity
E. Low viscosity

Q 5. A 31-year-old woman attends with a mesio-incisal fracture of an old composite restoration. The tooth was traumatized playing sport when the patient was 16 years old, and over 80% of the old composite restoration is remaining. Composite resin repair is planned, and the old restoration is air-abraded. After air abrasion, which single agent should be used prior to placement of the bonding agent?
A. Barium oxide
B. Camphorquinone
C. Hydroquinone
D. Silanizing agent [e.g., gamma-methacryloxypropyl-trimethoxysilane (gamma-MPTS)]
E. Tri-ethylene glycol dimethacrylate (TEGMA)

Q6. A 52-year-old man recently required a disto-occlusal amalgam restoration adjacent to a gold shell crown. At a subsequent appointment, a silver/brown circular stain is noticed around the contact point on the gold shell crown. Which single process has most likely caused the discoloration?
A. Electrochemical etching
B. Galvanic corrosion
C. Intergranular ion exchange
D. Mechanical damage during cavity preparation

Q7. A 36-year-old man requires multiple composite restorations to restore his worn anterior maxillary teeth. The restorations are to be placed at an increased vertical dimension, using the Dahl approach. Which single type of composite is most appropriate for these restorations?
A. Compomer
B. Flowable composite
C. Microfilled composite
D. Nanohybrid composite
E. Silorane composite

Q8. A 66-year-old man is having his edentulous maxilla restored. The residual ridge is a Class III ridge with minor anterior undercut. He attends for an abutment-level, open-tray impression for a full arch implant-supported bridge. Which single impression material is the most appropriate to use?
A. Addition-cured silicone [polyvinylsiloxane (PVS)]
B. Alginate
C. Condensation-cured PVS
D. Impression plaster
E. Polyether

Q9. An impression of a dentulous quadrant was taker with a medium- consistency polyether impression material in a custom-made acrylic tray. The normal relief of 2 mm was provided between the tray and the oral structures. After removal of the impression, tearing was noted at several locations. What can be the possible cause for the tearing of impression?
A. Improper isolation
B. Inadequate relief
C. Medium body should not have been used
D. Snap removal

Q 10. A 46-year-old man has had four permanent lower molars prepared for gold onlays to manage his generalized moderate toothwear. The preparations have minimal retention or resistance form. What single material is the most appropriate for cementation?
A. Glass-ionomer cement
B. Polycarboxylate cement
C. Resin cement
D. Resin-modified glass-ionomer cement
