Question 22 (part 2) · LDEK · Trauma to permanent teeth
Choose false statements regarding treatment of apex fracture in permanent teeth:
1) the coronal fragment is to be immediately repositioned, following radiographic confirmation of accuracy;
2) the tooth should be stabilized with inflexible splint for 4 weeks;
3) the root fracture in the neck area is stabilized up to 4 months;
4) in case of significant displacement of the coronal part, this fragment should be removed and apical fragment should be left for spontaneous resorption;
5) in case of pulp necrosis, RTC should be performed in the coronal fragment up to the fracture line, and apical fragment should be removed.
Correct answer is:
2) the tooth should be stabilized with inflexible splint for 4 weeks;
3) the root fracture in the neck area is stabilized up to 4 months;
4) in case of significant displacement of the coronal part, this fragment should be removed and apical fragment should be left for spontaneous resorption;
5) in case of pulp necrosis, RTC should be performed in the coronal fragment up to the fracture line, and apical fragment should be removed.
