氫氧化鈣糊劑聯合牙髓血運重建術治療年輕恒牙牙髓壞死的臨床效果分析

[摘要]目的：觀察氫氧化鈣糊劑聯合牙髓血運重建術治療年輕恒牙牙髓壞死的效果。方法：選取2020年3月-2021年12月筆者醫院收治的年輕恒牙牙髓炎壞死患者94例，按隨機數字表法分為對照組（給予三聯抗生素糊劑聯合牙髓血運重建術治療）和觀察組（給予氫氧化鈣糊劑聯合牙髓血運重建術治療），各47例。對比兩組臨床癥狀評分、臨床療效、疼痛情況、牙根長度、根管壁厚度、滿意度評分及不良反應。結果：治療后，觀察組牙齦腫脹、叩痛、牙齒松動評分均低于對照組（均P＜0.05）。觀察組總有效率（97.87% vs.85.11%）高于對照組（P＜0.05）。觀察組治療后6、12個月視覺模擬疼痛評分（VAS）均低于對照組（P＜0.05）。觀察組牙根長度、根管壁厚度均高于對照組（均P＜0.05）。觀察組牙齒色澤、咬合度及整體美觀性滿意度評分均高于對照組（均P＜0.05）；兩組咀嚼功能滿意度評分及治療后不良反應發生率對比，差異均無統計學意義（均P＞0.05）。結論：年輕恒牙牙髓壞死用氫氧化鈣糊劑聯合牙髓血運重建術治療可改善臨床癥狀，提高臨床療效，降低術后疼痛，促進牙根發育，提高患者滿意度，且安全可靠。

Abstract： Objective" To observe the effect of calcium hydroxide paste combined with pulp revascularization in the treatment of pulpitis and necrosis of young permanent teeth. Methods" 94 young patients with pulpitis and necrosis of permanent teeth admitted to the hospital from March 2020 to December 2021 were randomly divided into the control group （treated with triple antibiotic paste combined with pulp revascularization） and the observation group （treated with calcium hydroxide paste combined with pulp revascularization）， with 47 cases each. The clinical symptom score， clinical efficacy， pain， root length， root canal wall thickness， satisfaction score and adverse reactions were compared between the two groups. Results" After treatment， the scores of gingival swelling ， percussion pain ， tooth mobility" in the observation group were lower than those in the control group （ all P＜0.05）. The total effective rate of the observation group （97.87% vs. 85.11%） was higher than that of the control group （P＜0.05）. The visual analogue pain score （VAS） of the observation group was lower than that of the control group at 6 and 12 months after treatment （P＜0.05）. After treatment， the root length" and root canal wall thickness in the observation group were higher than those in the control group （all P＜0.05）. The satisfaction scores of tooth color， occlusion degree and overall aesthetics in the observation group were higher than those in the control group （all P＜0.05）. There was no statistical difference between the two groups in masticatory function satisfaction score（P＞0.05）. There was no statistical difference in the incidence of adverse reactions between the two groups after treatment （P＞0.05）. Conclusion" The treatment of pulpitis necrosis of young permanent teeth with calcium hydroxide paste combined with pulp revascularization can improve clinical symptoms， improve clinical efficacy， reduce postoperative pain， promote root development， improve patient satisfaction， and is safe and reliable.
