The aim of this study is to compare the clinical outcomes of Mineral Trioxide Aggregate (MTA) and calcium hydroxide pulp capping after complete caries removal.
In 73 regular patients (47 women, 26 men; age 20.65±3.02 years), having at least one deep carious lesion was recruited. Following complete caries removal, the pulp was indirectly capped with either MTA(n=51) or calcium hydroxide (n =49), randomly. Final restoration with a resin-based composite in a single session was performed. Clinical parameters including pulp vitality, sensitivity to cold or heat stimulants, percussion tests and discomfort during chewing and color were recorded after 6 months, 1 year, 2- year, 3- year and 4- year. Data were analysed statistically (p<0.05).
After 4- year, the survival rates were 86% (for MTA), and 82.9% (for calcium hydroxide). Totally, 8 teeth from calcium hydroxide group and 7 teeth from MTA group were endodontically treated. No significant difference was detected between the groups in terms of pulp vitality (p=0.613). Grey discoloration rate was 63% in MTA group.
Both pulp-capping materials, MTA and calcium hydroxide showed similar clinically successful performance in terms of pulp vitality in the treatment of deep dentin caries lesions after 4- year.
本研究旨在比较去除全部龋坏组织后，使用三氧化矿物凝聚体（MTA）和氢氧化钙进行牙髓盖髓术的临床效果。
招募了73名普通患者（47名女性，26名男性；年龄20.65±3.02岁），这些患者至少有一处深龋病变。在完全去除龋坏组织后，随机用MTA（n = 51）或氢氧化钙（n = 49）对牙髓进行间接盖髓。在一次就诊时用树脂基复合材料进行最终修复。在6个月、1年、2年、3年和4年后记录临床参数，包括牙髓活力、对冷或热刺激的敏感性、叩诊试验以及咀嚼时的不适感和牙齿颜色。对数据进行统计学分析（p<0.05）。
4年后，MTA组的生存率为86%，氢氧化钙组为82.9%。氢氧化钙组共有8颗牙齿和MTA组7颗牙齿接受了根管治疗。两组在牙髓活力方面未检测到显著差异（p = 0.613）。MTA组的牙齿变色率为63%。
在治疗深龋病变4年后，MTA和氢氧化钙这两种盖髓材料在牙髓活力方面均显示出相似的临床成功表现。
