Study Notes
Diagnosing Cracked Tooth
- A common method to diagnose a cracked tooth is by using a bite test.
Alveolar Fractures
- The recommended splinting time for teeth with alveolar fractures is 2-4 weeks.
File Types
- An active cutting tip is a characteristic of a K-type file.
- A C+ file is commonly used to negotiate calcified canals.
- The cutting length of an ISO file is 16mm.
Pain Transmission
- A-delta fibers transmit sharp pain, while C-fibers transmit dull pain.
Tissue Healing
- The best material that allows tissue healing around the apex is calcium hydroxide.
Patency File
- A patency file is a type of file used to maintain apical patency.
Fungi in Failed Root Canals
- Candida and Aspergillus are commonly found in failed root canal treatments.
pH Levels
- The highest pH is found in calcium hydroxide (pH 12.5).
- Sodium hypochlorite has a pH of 11-12.
Cracked Tooth Symptoms
- Releasing the bite in a cracked tooth can cause pain.
Sodium Hypochlorite Accidents
- Sodium hypochlorite accidents often result from inadequate irrigation or instrumentation.
Irreversible Pulpitis
- The recommended emergency treatment for irreversible pulpitis is pulp necrosis.
Instrumentation
- If the master apical file does not reach the working length, the appropriate management is to use a pre-curved file or a file with a greater taper.
Tooth Anatomy
- A single canal is most commonly found in the maxillary central incisor.
- Approximately 15% of teeth have a single canal with two foramens.
Bacteria in Necrotic Pulp
- The predominant bacteria in the necrotic pulp are anaerobic bacteria.
Dental File Use
- The primary use of a dental file is for shaping and cleaning the root canal.
Root Canal Treatment
- A diagnostic test to confirm a periapical radiolucency is a periapical radiograph.
- Swelling, pain, and a chlorine-like smell during root canal treatment may indicate a sodium hypochlorite accident.
Avulsed Teeth
- The recommended splinting time for an avulsed tooth if it was replanted within less than 60 minutes is 1-2 weeks.
- The most common complication associated with the use of Mineral Trioxide Aggregate (MTA) is tooth discoloration.
Gutta-Percha
- The primary component of gutta-percha is trans-isoprene.
- The primary components of gutta-percha used in root canal obturation are trans-isoprene and zinc oxide.
