Study Notes
- Two possibilities in traumatic injuries: apical translocation with luxation injuries or intrusion injuries in permanent teeth.
- Apical translocation: tooth displacement from its normal position, can cause various problems including pulpal damage and survival rates.
- Luxation injuries: teeth are displaced from their socket, repositioning is crucial for good prognosis, splinting and root canal therapy are necessary.
- Follow-up appointments for luxation injuries: 2 weeks, 4 weeks, 6-8 weeks, 6 months, and yearly for at least 5 years.
- Intrusion injuries: teeth are forced into their socket, spontaneous re-eruption is rare, and surgical or orthodontic intervention is usually required.
- Surgical reposition for intrusion injuries is quick and cost-effective but can cause additional damage.
- Clinical management of avulsed egg-tooth (primary tooth): keep calm, find tooth, rinse with water, and seek emergency dental treatment.
- Success rate for avulsed permanent teeth decreases with extraoral dry time.
- Storage media for avulsed teeth: milk, saline, and vestibule of mouth can help maintain tooth viability.
- Milk is a good storage medium due to its physiological osmolarity and pH level.
- Emergency visit: root preparation depends on tooth maturity and age, and dry time.
- Splinting time for different types of injuries varies from 2 weeks to 4 months.
- Patient instructions: follow-up visits, home care, and avoiding contact sports are essential for optimal healing.
- Root resorption following tooth avulsion is inflammatory in nature and can be self-limiting or progressive.
- Radiographs with different angulations are crucial for diagnosing root resorption.
