The aim of the study was to compare the clinical and radiographic evaluation of pulpotomy using mineral trioxide aggregate (MTA), calcium silicate-based cement (Biodentine), and Er,Cr:YSGG laser in primary molars.
Fifty-four primary teeth were selected for this study as per the inclusion and exclusion criteria in the age group of 4-9 years and then randomly allocated to three groups A, B & C. In group A, after removal of coronal pulp, MTA was placed at the floor of pulp chamber. In group B, calcium silicate-based cement (Biodentine) was placed at the floor of pulp chamber. In group C, decontamination of the cavity was done with Er,Cr:YSGG laser. This was followed by placement of permanent restorative material in all the groups. Clinical and radiographic success was evaluated at 3, 6 and 9 months. Data analysis was performed using Statistical Package for the Social Science-21 (SPSS-21).
At the end of 9 months, overall success rate of pulpotomy was 85.5%. There was no significant difference among the three groups (p > 0.05).
The study showed that the success of pulpotomy procedure is independent of the type of medicament used for pulpotomy. Moreover, the study also shows that Er,Cr:YSGG laser can be effectively used for pulpotomy procedures.
本研究的目的是比较使用三氧化矿物凝聚体(MTA)、硅酸钙基水门汀(生物陶瓷)和铒铬:钇-钪-镓石榴石(Er,Cr:YSGG)激光进行乳牙活髓切断术的临床和影像学评估。
根据纳入和排除标准,选取54颗4至9岁年龄组的乳牙,然后随机分为A、B、C三组。A组在去除冠髓后,将MTA放置于髓室底。B组在髓室底放置硅酸钙基水门汀(生物陶瓷)。C组用Er,Cr:YSGG激光对窝洞进行消毒。之后,所有组均放置永久性修复材料。在3、6和9个月时评估临床和影像学成功率。使用社会科学统计软件包21(SPSS-21)进行数据分析。
9个月末,活髓切断术的总体成功率为85.5%。三组之间无显著差异(p>0.05)。
该研究表明,活髓切断术的成功与用于活髓切断术的药物类型无关。此外,该研究还表明,Er,Cr:YSGG激光可有效地用于活髓切断术。
