The objectives of this study was to check the outcome of the direct and indirect pulp capping procedure using MTA (Mineral Trioxide Aggregate) by comparing the pre-and post-operative pain by using VAS scale, associating the pre- and post- operative changes in intraoral periapical radiograph and clinical symptoms.
In this prospective clinical study 10 cases (5 for direct and 5 for indirect) with deep carious lesions (symptomatic) with no periapical changes were selected for the trial. The participants were subjected to deep caries management procedure under rubber dam where MTA is placed as pulp capping material followed by immediate restoration with sandwich technique using composite resin. The participants were followed up at recall visits of 1 month, 3 months, 6 months and 1 year intervals for clinical and radiographic evaluation.
The results of the study, analyzing the VAS, clinical symptoms and radiographic changes did not show any signs of pain, clinical and radiographic symptoms at 1 month, 3 months, 6 months and 1 year intervals.
It was concluded that MTA can be used for deep caries management as a pulp capping material which being equivalent to calcium hydroxide.
本研究旨在通过视觉模拟评分（VAS）比较直接和间接牙髓盖髓术使用 MTA（三氧化矿物凝聚体）的治疗效果，结合口腔内根尖周放射影像和临床症状的术前术后变化，评估 MTA 作为牙髓盖髓材料的疗效。
本前瞻性临床研究纳入 10 例（5 例直接法，5 例间接法）深龋（有症状）但无根尖病变的患者。在橡皮障隔离下进行深龋去腐处理，使用 MTA 作为牙髓盖髓材料，然后采用复合树脂三明治修复技术进行即刻修复。在 1 个月、3 个月、6 个月和 1 年的随访中，通过临床和放射影像学评估来观察患者的临床和放射影像学变化。
研究结果分析显示，在 1 个月、3 个月、6 个月和 1 年的随访中，VAS、临床症状和放射影像学均未显示任何疼痛、临床或放射影像学症状。
MTA 可作为牙髓盖髓材料用于深龋的治疗，其效果与氢氧化钙相当。
