Root fractures |
|
¨ Fractures in the apical and middle 1/3rds of the root normally take an oblique course ¨ Take radiographs with various angulations to diagnose fracture type and location
Treatment of root fractures: 1. To facilitate pulpal and periodontal healing it is essential that a displaced coronal fragment be optimally repositioned and reduced 2. Splint for 3 months (rigid) 3. Check for pulpal complications after 3/52, 6/52 and 3/12 4. If pulpal necrosis occurs extirpate to level of fracture and dress with calcium hydroxide
Prognosis of root fractures: ¨ Pulpal necrosis in about 25% of cases— related to displacement of the coronal fragment and mature root formation ¨ Healing by hard tissue union is optimal, interposition of connective tissue is acceptable ¨ It is not presently known how the different forms of healing affect the life expectancy.
