Use of ultrasound, color Doppler imaging and radiography to monitor periapical healing after endodontic surgery

Abstract

This study evaluated the effectiveness of ultrasound, color Doppler imaging and conventional radiography in monitoring the post-surgical healing of periapical lesions of endodontic origin. Fifteen patients who underwent periapical surgery for endodontic pathology were randomly selected. In all patients, periapical lesions were evaluated preoperatively using ultrasound, color Doppler imaging and conventional radiography, to analyze characteristics such as size, shape and dimensions. On radiographic evaluation, dimensions were measured in the superoinferior and mesiodistal direction using image-analysis software. Ultrasound evaluation was used to measure the changes in shape and dimensions on the anteroposterior, superoinferior, and mesiodistal planes. Color Doppler imaging was used to detect the blood-flow velocity. Postoperative healing was monitored in all patients at 1 week and 6 months by using ultrasound and color Doppler imaging, together with conventional radiography. The findings were then analyzed to evaluate the effectiveness of the 3 imaging techniques. At 6 months, ultrasound and color Doppler imaging were significantly better than conventional radiography in detecting changes in the healing of hard tissue at the surgical site (P < 0.004). This study demonstrates that ultrasound and color Doppler imaging have the potential to supplement conventional radiography in monitoring the post-surgical healing of periapical lesions of endodontic origin.

Value of color Doppler ultrasonography and radiography for the assessment of the cancellous bone scaffold coated with nano-hydroxyapatite in repair of radial bone in rabbit

“…27 (2) so it promotes the reparative process of bone defect. As per expected no local reaction was seen during first two weeks in both groups but sonographically sprouting small blood vessels network at end of two weeks in Group II, as reported by Williamson et al 9 Hamanishi et al 10 and Tikku et al 11 With radiographic findings of intercortical callus formation within 60 days were good indication for local reaction of cancellous bone scaffold coated with nano-HA to act as stimulator to provide suitable bed for blood vessels penetration as compared to Group I. The status of bone, the vascularity, callus formation and viability of bone is a very important factor, in assessing the successful outcome of various surgical procedures.…”

Application of ultrasonography in dentistry

“…Gundappa et al [22] reported that US demonstrated a high diagnostic accuracy in the differentiation of periapical gran- ulomas and radicular cysts with a side-by-side comparison between US and hisopathology. Recent studies suggest that the Doppler imaging could be promising technique for monitoring the healing of periapical lesions [23][24][25].…”

Fakat bu görüntüler iki boyutlu olduğu için bu yapıların tam olarak lokalizasyonları yapılamaz.…”
