Patients with end-stage renal disease are of increased risk when undergoing extraction of teeth because they
1. Have an increased tendency to bleed
2. Are susceptible to infections
3. Are often on steroid therapy
4. All of the above
Oral Surgery
Answer: 4
Patients with end-stage renal disease are at increased risk during tooth
extraction due to several factors. They often have an increased tendency to
bleed due to platelet dysfunction and are susceptible to infections due to
compromised immunity. Additionally, they are often on steroid therapy, which can
affect wound healing and increase the risk of infection.

One wants to anaesthetise the inferior alveolar nerve at the point at which it exits from the mandibular canal, so the injection site most often located in
1) Between first and second molars inferior to the root apices
2) Between first and second molar superior to root apices
3) Between first and second premolars inferior to root apices
4) Between first and second premolars superior to root apices
Oral Surgery
Answer: 3
The inferior alveolar nerve block (IANB) is a common technique used in dentistry to anesthetize the mandibular teeth, including the molars. The nerve exits the mandibular foramen and runs along the mandibular canal before it branches into the incisive and mental nerves. For effective anesthesia, the injection site is typically located between the first and second premolars, aiming towards the medial surface of the ramus of the mandible, and the needle is inserted until it is just inferior to the root apices of these teeth. This position allows the anesthetic solution to reach the nerve as it emerges from the bone and before it gives off its major branches, thus achieving profound anesthesia for the procedure.
