UNASSIGNED: A total of 101 adult permanent molars with irreversible pulpitis, in individuals over 12 years old, were categorized based on pulp chamber calcification observed in radiographic images by two endodontists. Subsequently, full pulpotomy procedures were performed, achieving hemostasis, and applying a 2 mm layer of calcium-enriched mixture (CEM) cement as a pulp covering agent. After 48 hours, the setting of the CEM cement was verified, followed by the application of a layer of resin-modified glass-ionomer. The tooth was then restored using amalgam. Clinical and radiographic evaluations were conducted at 6-month and 1-year follow-ups by blinded endodontists. Success rates were compared using Fisher\'s exact test and logistic regression tests with a significance level of 0.05.
UNASSIGNED: Among the 97 patients with 6-month and 1-year follow-ups, all achieved clinical success. Radiographic success rates were 99% at 6 months and 96.9% at 1 year, regardless of pulp calcification. In the 6-month follow-up, success rates were 98.07% for non-calcified pulp chambers and 100% for calcified pulp chambers. At the 1-year follow-up, success rates were 96.1% and 97.8%, respectively. Statistical analysis showed no significant difference in radiographic success rate between the two groups at both follow-ups (P>0.05).
UNASSIGNED: Full pulpotomy using CEM cement is a successful treatment for adult permanent teeth with calcified and non-calcified pulp chambers presenting signs and symptoms of irreversible pulpitis up to a 1-year follow-up. This study provides compelling evidence that vital pulp therapy can be effectively employed in the pulpotomy of calcified teeth, at least in the short term.
■总共101个患有不可逆性牙髓炎的成人恒磨牙,在12岁以上的人中,根据两名牙髓医生在放射图像中观察到的牙髓腔钙化进行分类。随后,进行了完整的牙髓切除术,实现止血,并且施加2mm的富钙混合物(CEM)水泥层作为纸浆覆盖剂。48小时后,验证了CEM水泥的凝固,然后施加一层树脂改性的玻璃离聚物。然后使用汞合金修复牙齿。临床和影像学评估在6个月和1年的随访中由盲牙髓医生进行。使用Fisher精确检验和逻辑回归检验比较成功率,显著性水平为0.05。
■在97例经6个月和1年随访的患者中,均取得临床成功。6个月和1年的X线摄影成功率分别为99%和96.9%。不管牙髓钙化。在6个月的随访中,非钙化浆室的成功率为98.07%,钙化浆室的成功率为100%。在1年的随访中,成功率分别为96.1%和97.8%,分别。经统计学分析,两组患者的X线摄影成功率差异无统计学意义(P>0.05)。
■使用CEM骨水泥的全牙髓切除术是一种成功的治疗成人恒牙钙化和非钙化牙髓腔出现不可逆牙髓炎的体征和症状,随访1年。这项研究提供了令人信服的证据,表明重要的牙髓疗法可以有效地用于钙化牙齿的牙髓切除术,至少在短期内。
