■在龋齿牙髓暴露的恒牙中进行重要部分牙髓切除术(PP)或宫颈牙髓切除术(CP)可保持牙齿活力,促进牙髓愈合,降低治疗成本,缩短治疗时间,这是治疗不合作儿童的一个重要因素。这项回顾性研究的目的是比较重要的龋齿暴露恒牙中部分和CP的临床和影像学结果。
■所有有龋齿牙髓暴露的重要恒牙,在2017-2019年期间,由一个牙科中心的两名操作员使用三氧化二矿骨料(MTA)进行牙髓切除术,包括在研究中。术后6-57个月对97名儿童和青少年(平均年龄10.9岁)的约118颗恒牙进行了评估。
■CP和PP的总成功率分别为82.5和80.8%,分别(p=不显著)。显着影响成功率的唯一因素是术前根尖周病理的存在。没有这种病理的牙齿显示出87.3%的成功率,而在术前牙周膜(PDL)增大或根尖周围的放射透明度的牙齿中,分别为74.1和58.3%。分别(p=0.0301)。人口统计变量,牙齿的成熟状态,牙齿类型(门牙,前磨牙,摩尔),术后变量,例如射线照相牙本质桥的存在,在随访期间,牙髓部分或全部消失,并且在召回检查期间最终修复的完整性不影响治疗的成功率。
■在儿童和青少年中暴露于龋齿牙髓的重要恒牙中的部分和CP可能是完全根管治疗(RCT)的可靠替代方法。

UNASSIGNED: Vital partial pulpotomy (PP) or cervical pulpotomy (CP) in carious pulp-exposed permanent teeth preserves tooth vitality, promotes pulp healing, decreases treatment costs, and shortens treatment duration, which is a significant factor in treating noncooperative children. The aim of this retrospective study was to compare clinical and radiographic outcomes of partial and CP in vital carious-exposed permanent teeth.
UNASSIGNED: All vital permanent teeth with carious pulp exposure, treated by pulpotomy using mineral trioxide aggregate (MTA) during 2017-2019, by two operators in one dental center, were included in the study. Around 118 permanent teeth in 97 children and adolescents (mean age 10.9 years) were evaluated 6-57 months postoperatively.
UNASSIGNED: The total success rates of CP and PP were 82.5 and 80.8%, respectively (p = nonsignificant). The only factor that significantly affected the success rate was the presence of preoperative periapical pathology. Teeth without such pathology showed an 87.3% success rate compared to 74.1 and 58.3% in teeth with preoperative enlarged periodontal ligament (PDL) or with periapical radiolucency, respectively (p = 0.0301). Demographic variables, maturation state of the tooth, type of tooth (incisor, premolar, molar), postoperative variables, such as the presence of radiographic dentinal bridge, partial or full obliteration of the pulp during the follow-up period, and the integrity of the final restoration during the recall examinations did not affect the success rate of the treatment.
UNASSIGNED: Partial and CP in vital permanent teeth with carious pulp exposure in children and adolescents might be a reliable alternative to full root canal treatment (RCT).
