OBJECTIVES
To evaluate the outcome of vital pulp therapy in primary teeth with irreversible pulpitis by using calcium-enriched mixture (CEM) cement according to clinical and radiographic assessment.
PARTICIPANTS AND METHODS
Fifty primary molar teeth with irreversible pulpitis in 50 children aged 6-8 years underwent pulpotomy using CEM cement as the dressing material. Following pulpotomy, pain intensity was evaluated by use of a visual analog scale at 1 and 7 days from the treatment and in clinical appointments at 3, 6 and 12 months after baseline. Radiographic evaluation was performed at 6 and 12 months. Data were analyzed using the McNemar test.
RESULTS
A total of 42 children (mean age 7.26 ± 0.82 year) completed the study. After one day treatment 56 % of children reported complete relief of pain and after 7 days 62% reported the same. However, two children complained of increased pain 1 day after treatment. None of the children reported pain in the subsequent appointments. One child complained of tenderness in percussion after 6 months. Pulp canal obliteration was the most common change in the radiographic assessment. There was no significant difference between clinical (92.8%) and radiographic (90.4%) success (p=0.990).
CONCLUSION
Pulpotomy using CEM cement could present a successful treatment in primary molar teeth with irreversible pulpitis.
目的
根据临床和影像学评估，评估使用富钙混合物（CEM）粘结剂对患有不可逆性牙髓炎的乳牙进行牙髓活力治疗的效果。
参与者与方法
选取50名6至8岁患有不可逆性牙髓炎的儿童的50颗乳磨牙，采用CEM粘结剂作为敷料进行牙髓切断术。牙髓切断术后，在治疗后1天和7天以及基线后3、6和12个月的临床复诊时，使用视觉模拟量表评估疼痛强度。在6个月和12个月时进行影像学评估。使用McNemar检验分析数据。
结果
共有42名儿童（平均年龄7.26±0.82岁）完成了研究。治疗1天后，56%的儿童报告疼痛完全缓解，7天后，62%的儿童报告疼痛完全缓解。然而，有两名儿童在治疗后1天抱怨疼痛加剧。在随后的复诊中，没有儿童报告疼痛。有一名儿童在6个月后抱怨叩诊时有压痛。牙髓腔闭塞是影像学评估中最常见的变化。临床成功率（92.8%）和影像学成功率（90.4%）之间无显著差异（p = 0.990）。
结论
使用CEM粘结剂进行牙髓切断术可能是治疗患有不可逆性牙髓炎的乳磨牙的一种成功方法。
