【摘要】：目的:通過對(duì)根尖孔未發(fā)育完全的年輕恒牙實(shí)施牙髓血運(yùn)重建治療,并追蹤隨訪患牙9~24個(gè)月,觀察牙髓血運(yùn)重建術(shù)的臨床療效。方法:對(duì)9例(11顆牙)患牙進(jìn)行常規(guī)開髓,清除壞死的牙髓組織,2.5%的次氯酸鈉和17%的EDTA溶液沖洗后封入三聯(lián)抗生素糊劑。待患牙臨床癥狀消失后,對(duì)其進(jìn)行牙髓血運(yùn)重建術(shù),嚴(yán)密冠方封閉,定期復(fù)診觀察。結(jié)果:9例(11顆牙)年輕恒牙經(jīng)牙髓血運(yùn)重建術(shù)治療后,臨床癥狀全部消失。其中,6顆牙根尖孔閉合,牙根發(fā)育,牙髓電活力測(cè)試有反應(yīng);4顆牙根尖孔閉合,牙根發(fā)育,牙髓電活力測(cè)試無反應(yīng);1顆牙治療失敗。結(jié)論:牙髓血運(yùn)重建術(shù)能使牙根繼續(xù)發(fā)育,為治療牙髓炎癥、壞死和根尖周感染的年輕恒牙提供了可選擇的方法。
[Abstract]:Objective: to observe the clinical effect of pulp revascularization in young permanent teeth with incomplete apical foramen. Methods: 9 cases (11 teeth) were treated with conventional pulp opening, the dead pulp tissue was removed, 2.5% sodium hypochlorite and 17% EDTA solution were washed and sealed with triple antibiotic paste. After the clinical symptoms of the affected teeth disappeared, the pulp revascularization was performed, the crown was tightly closed, and the diagnosis was observed regularly. Results: the clinical symptoms of 9 cases (11 teeth) of young permanent teeth disappeared after pulp revascularization. Among them, 6 teeth had apical foramen closure, root development, pulp electrical vitality test, 4 teeth had apical foramen closure, root development, pulp electrical vitality test had no response, 1 tooth treatment failed. Conclusion: pulp revascularization can make the root continue to develop and provide an alternative method for the treatment of pulpitis, necrosis and periapical infection of young permanent teeth.
