Case -2- 50. A 22-year-old patient presents with a deep carious lesion on tooth #36. The tooth responds positively to cold testing with no lingering pain, and there is no history of spontaneous pain or signs of periapical pathology on the radiograph. The caries extends close to the pulp but there is no pulp exposure during excavation. What is the most appropriate treatment approach? a) Direct pulp capping with calcium hydroxide b) Root canal treatment c) Extraction of the tooth d) Indirect pulp capping with selective caries removal e) Full pulpotomy with MTA

48. What is the major difference between partial pulpotomy and full pulpotomy? a) In partial pulpotomy, all pulp tissue is removed, while in full pulpotomy, only inflamed pulp tissue is removed b) Partial pulpotomy is done only in primary teeth, while full pulpotomy is done in permanent teeth c) Partial pulpotomy removes only superficial inflamed pulp, while full pulpotomy removes all coronal pulp d) Full pulpotomy has a higher success rate than partial pulpotomy e) Full pulpotomy requires no follow-up appointments

Case -1- 43 .During cavity preparation on a mandibular molar, a dental student notices that the dentin surface appears dull and slightly yellow, and the explorer tends to catch slightly on the surface. To improve adhesion, they decide to etch the dentin before placing a resin-based composite. Which of the following best explains why this etched dentin becomes a challenge for bonding? a. Dentin becomes brittle after etching and fractures easily b. Etching decreases the tensile strength of enamel rods c. Acid etching removes the smear layer, increasing dentinal permeability and outward fluid flow d. The etched dentin becomes too dry to bond effectively e. Etching causes permanent damage to odontoblasts and leads to necrosis

40. Which of the following statements about dentinal tubules is CORRECT? a. They extend from the DEJ to the cementoenamel junction. b. Each tubule is filled with an odontoblastic nucleus. c. They are lined by intertubular dentin, which is more mineralized than peritubular dentin. d. Tubule diameter increases closer to the pulp. e. In mature dentin, the odontoblastic process reaches the DEJ.
