Indirect pulp treatment (IPT) is a minimally invasive procedure based on the application of a protective liner on the affected dentin, thereby preserving the pulp vitality.
This study aims to evaluate and compare the clinical and radiographic outcomes of IPT when a layer of calcium hydroxide (Dycal), mineral trioxide aggregate (MTA), or Biodentine was placed over the affected dentin in primary molars.
A clinical trial with sample size of 45 primary molars between the age group of 4-9 years, of which 15 teeth were considered, each for Group I (Dycal), Group II (MTA), and Group III (Biodentine). Measurements on digitized radiographs were made at baseline, 3, and 6 months using Corel Draw software.
One-way ANOVA and tests indicated a statistically significant difference in dentin thickness ( < 0.05) in all the groups. Within Group I, the thickness of dentin was 0.066 ± 0.009 mm at 3 months and 0.099 ± 0.011 mm at 6 months. In Group II, 0.081 ± 0.010 mm at 3 months and 0.123 ± 0.016 mm at 6 months. In Group III, 0.102 ± 0.021 mm at 3 months and 0.154 ± 0.022 mm at 6 months.
Clinically, 100% success rate was observed in all the groups whereas radiographically, Biodentine was superior to both the groups.
间接盖髓术（IPT）是一种基于在患牙本质上应用保护衬层的微创操作，从而保留牙髓活力。
本研究旨在评估和比较在乳牙患牙本质上放置一层氢氧化钙（Dycal）、三氧化矿物凝聚体（MTA）或生物活性玻璃（Biodentine）时间接盖髓术的临床和影像学结果。
一项针对4至9岁年龄组45颗乳牙的临床试验，其中每组15颗牙，分别为第一组（Dycal）、第二组（MTA）和第三组（Biodentine）。使用Corel Draw软件在基线、3个月和6个月时对数字化X线片进行测量。
单因素方差分析和检验表明，所有组的牙本质厚度存在统计学显著差异（P<0.05）。在第一组中，3个月时牙本质厚度为0.066±0.009毫米，6个月时为0.099±0.011毫米。在第二组中，3个月时为0.081±0.010毫米，6个月时为0.123±0.016毫米。在第三组中，3个月时为0.102±0.021毫米，6个月时为0.154±0.022毫米。
临床上，所有组的成功率均为100%，而在影像学上，生物活性玻璃优于其他两组。
