ProsthodonticsThe finish line of a crown preparation can be placed supragingivally or subgingivally depending on the clinical situation. Subgingival finish lines may be necessary to achieve proper aesthetics, especially in cases where the margin needs to be hidden beneath the gingival tissue. However, it is important to avoid placing the finish line too far subgingivally, as this can complicate oral hygiene and lead to periodontal issues.

The significant differences between self-etch
primers and total-etch primers are: Wetness of dentine: In total-etch, dentine must be kept moist
after etching to prevent collagen collapse. In self-etch, no rinsing step is required, so
dentine wetness is not critical. Time of application: Total-etch involves separate etching, rinsing,
and priming steps → longer procedure. Self-etch combines etching and priming in one
step → faster. Removal of smear layer: Total-etch completely removes the smear layer
with phosphoric acid. Self-etch modifies and incorporates the smear
layer into the hybrid layer. Bond strength: Both systems can achieve comparable bond strength
to enamel and dentine when properly applied. Hence, bond strength is NOT a significant difference
between the two systems.Explanation

Oral SurgeryThe inferior alveolar nerve exits the mandibular foramen and runs in the mandibular canal before it branches off to supply the teeth, including the second premolar. To anesthetize the nerve at this point, the injection site is commonly located between the first and second premolars, inferior to the root apices, where the nerve is relatively superficial and accessible.

Oral and Maxillofacial SurgeryNon-absorbable sutures are ideal for situations where sustained support is required beyond the typical healing period, ensuring that the tissue remains stable during the recovery process.

Teratomas are tumors that originate from pluripotent stem cells and are known to contain tissues derived from all three embryonic germ layers: the ectoderm (e.g., skin, nerve tissue), mesoderm (e.g., muscle, bone, fat), and endoderm (e.g., gut epithelium, respiratory epithelium). Branchial cysts and thyroglossal cysts are generally derived from ectoderm and endoderm remnants. Dermoid cysts primarily contain ectodermal elements.
