The aim of this study was to compare calcium hydroxide plus points (CHPPs) with the conventional calcium hydroxide paste (CHP) clinically and radiographically as materials used in apexification treatment.
Sixteen children, each with at least one necrotic permanent central incisor requiring apexification treatment, were selected for this study. Twenty-two selected teeth were divided into two test groups (10 CHP and 12 CHPP). The children were recalled for clinical evaluations every 3 weeks, and their radiographical evaluations were carried out every 3 months. Mann-Whitney U and Fisher's exact tests were used to evaluate the differences between the groups.
The follow-up evaluations revealed that the success rate was 100% for CHP and 92% for CHPP. No statistically significant difference between the groups was observed (P > 0.05).
CHPP-treated central incisors requiring apexification demonstrated good success. CHPP can be used for cases in which traditional Ca(OH)(2) apexification is indicated as it has a similar outcome with CHP.
本研究旨在比较氢氧化钙加剂（CHPPs）与传统氢氧化钙糊剂（CHP）在牙髓切断术中的临床和影像学效果。
本研究选取了 16 名至少有一颗需要牙髓切断术的坏死恒中切牙的儿童。22 颗选定的牙齿被分为两组进行测试（10 颗 CHP 和 12 颗 CHPP）。每 3 周对儿童进行临床评估，每 3 个月进行影像学评估。采用曼-惠特尼 U 检验和 Fisher 确切概率法对组间差异进行评估。
随访评估显示，CHP 组的成功率为 100%，CHPP 组的成功率为 92%。两组间无统计学差异（P>0.05）。
需要牙髓切断术的中切牙用 CHPP 处理后效果良好。在传统的氢氧化钙根尖诱导成形术适用的情况下，可以使用 CHPP，因为它与 CHP 具有相似的效果。
