INTRODUCTION/PURPOSE: Surgically assisted rapid palatal expansion is used for the management of transverse maxillary deficiency in the early permanent dentition. The success depends on the maintenance of an adequate blood supply to the mobilized segments. The aim of this study was to assess the effects of corticotomy and midline osteotomy on the tooth pulpal blood flow.
MATERIAL
Laser Doppler flowmetry was applied as a non-invasive and reliable technique for the assessment of pulpal blood flow in the maxillary centrals, canines and first molars. The blood flow was investigated pre- and postoperatively, on the first, third, and seventh postoperative days bilaterally in 13 cases.
RESULTS
The results of this study indicate that ischaemia of the pulp can occur following osteotomy at the Le Fort I level.
CONCLUSION
Corticotomy 5mm above the dental apices and separating the midpalatal suture did not have any serious effect on pulpal blood flow in this study.
引言/目的：外科辅助快速腭扩展用于恒牙早期上颌横向发育不足的治疗。其成功与否取决于对移动节段充足血供的维持。本研究的目的是评估皮质切开术和中线截骨术对牙髓血流的影响。
材料
激光多普勒血流仪作为一种无创且可靠的技术，用于评估上颌中切牙、尖牙和第一磨牙的牙髓血流。对13例患者双侧在术前、术后第一天、第三天和第七天进行血流研究。
结果
本研究结果表明，在Le Fort I水平截骨后可发生牙髓缺血。
结论
在本研究中，根尖上方5mm处的皮质切开术及分离腭中缝对牙髓血流没有任何严重影响。
