What are the general ideal requirements for a temporary restorative material?
1) High compressive strength and good thermal conductivity
2) Low compressive strength and good thermal conductivity
3) High compressive strength and good marginal sealing
4) Low compressive strength and good marginal sealing
Temporary restorative materials should have low compressive strength (less than 35 MP1) and good marginal sealing to facilitate easy removal and minimize thermal microleakage.
Which feature is most desirable in a suture material to minimize
tissue reaction and reduce the risk of infection?
1) Braided structure
2) Synthetic monofilament
3) High tensile strength
4) Natural material composition
Oral and Maxillofacial Surgery Answer: 1
Synthetic monofilament sutures are preferred for their smooth surface, which reduces the risk of infection by preventing bacteria from being trapped in the suture material, thus promoting better healing outcomes.

What is the typical inheritance pattern of Hemophilia A?
1) Autosomal recessive
2) Autosomal dominant
3) Sex-linked recessive
4) Sex-linked dominant
Hemophilia A is typically inherited in a sex-linked recessive pattern, meaning it is caused by a mutation in a gene on the X chromosome. Males are more commonly affected since they have only one X chromosome, while females with one normal and one affected X chromosome are usually carriers and may exhibit mild symptoms.
