1/2. A two-probe laser Doppler flowmetry assessment as an exclusive diagnostic device in a long-term follow-up of traumatised teeth: a case report.

    The reliability of laser Doppler flowmetry in a two-probe assessment of pulpal blood flow is well known. The purpose of this case report was to determine its use as an exclusive and reliable tool for tooth vitality diagnosis in a long-term follow-up. As a result of a traumatic injury to a 24-year-old Caucasian female, tooth pulp vitality was studied in six maxillary front teeth over 30 weeks using two-probe laser Doppler flowmetry and current sensitivity tests. A similar assessment was repeated after 228 weeks. Confronted with an alveolar bone fracture with a tooth in the fracture line, one intrusion and several luxated teeth, current sensitivity tests are found not to be as reliable indicators of revascularisation, as significant results are obtained later (7 weeks) than using laser Doppler flowmetry tests (1 week). A pathway with ischaemia (3 weeks), hyperaemia (7 weeks) and restored blood supply in the pulp measured by laser Doppler flowmetry tests was found and avoided endodontic treatment. Teeth vascularisation evolved normally (228 weeks). Despite a strong indication in all sensitivity tests for endodontic treatment, the use of laser Doppler flowmetry tests was clear, more reliable than sensitivity tests and exclusive, as denervation was postponed and pulp vascularisation evident.

2/2. Surgical root restoration after external inflammatory root resorption: A case report.

    External inflammatory root resorption after a jaw fracture is rare. This report describes a case of extensive external root resorption in the middle third of the root of a mandibular right canine after a mandibular fracture involving the tooth socket. Because of delayed treatment and damage to the root caused by a surgical screw, root canal treatment was performed followed by surgical intervention. The resorptive defect was debrided and part of the root was rebuilt with conventionally setting restorative glass ionomer cement. Postoperative follow-up revealed complete healing.
