What passes through the apical foramen?
Blood vessels, lymphatic vessels and nerves
What is the ligament that attaches the cementum to the root?
Periodontal ligament
What is the alveolar process?
Tissue of the attachment apparatus which is the thickened ridge of bone that contains the tooth sockets (alveoli) on bones that hold teeth in the maxilla and mandible

Trigeminal, CN V
Which anesthetic is used for dental anesthesia?
0.5% Bupivacaine/Marcaine
What is local infiltration?
Deposition of local anesthetic directly at or near a small terminal nerve ending in the immediate area of treatment
What is a regional block/tooth nerve block?
Deposition of local anesthetic near a major nerve trunk at a greater distance from the area of treatment which provides a wider area of anesthesia
When is an Inferior Alveolar (IA) block used?
- For anesthesia of entire hemi mandible
- For fracture repair, removal of teeth or pain control
What is the target site of IA block?
Lingula
Where do you place the barrel for IA blocks?
Commissure of mouth opposite to the injection site
What is concussion of a tooth?
Minor injury to the tooth supporting structures without abnormal loosening or displacement of the tooth
What is the treatment of concussion of a tooth?
No treatment required
What is subluxation of a tooth?
Traumatic injury that results in a tooth, to varying degrees, loose in the socket
What is the treatment of subluxation?
- Gentle manipulation into proper position
- Splint if necessary
What is tooth avulsion?
Traumatic injury where the tooth has been removed from the socket
How do you treat a tooth avulsion?

What is pulpitis?
Inflammation of dental pulp resulting from untreated caries, trauma or multiple restorations
Principle sx of pulpitis

Treatment of pulpitis
- remove decay
- restore damaged tooth, sometimes root canal

Treatment of reversible pulpitis
Drill and fill
Treatment of irreversible pulpitis
Root canal then crown
Apical periodontitis and osteomyelitis can lead to?
Ludwig’s angina
What is periapical abscess?
Collection of pus at the apex of a tooth, usually caused by an infection that has spread from the apical foramen of a tooth with irreversible pulpitis to surrounding tissues
What is the sequelae of periapical perionditis?
Periapical abscess
What is a periodontal abscess?
Collection of pus that occurs alongside of a tooth
