Abstract

Introduction

The aim of this prospective study was to investigate the 1-year pulp survival of cracked teeth with reversible pulpitis managed with initial stabilization using orthodontic bands, followed by coronal coverage restorations.

Methods

One-hundred-and-twenty-five patients with a cracked tooth with reversible pulpitis each were recruited. Preoperative patient and tooth data were collected. After definitive pulp diagnoses were determined following an interim period of orthodontic banding, coronal coverage restorations were placed. Cox and logistic regression analyses were used to assess possible prognostic factors and to correlate initial time to pulp stabilization while in orthodontic bands with eventual outcome. Pulp survival was determined using both clinical and radiographic findings.

Results

One-hundred-and-six cracked teeth were followed up at 1 year. Pulp survival based on clinical and radiographic findings was found in 81 teeth (76.4%). Out of 25 failures, 11 (44%) required root canal treatment (RCT) in the orthodontic band stage and 10 (40%) required RCT during the process of or after coronal coverage restorations. Four teeth (16%) had incidental findings of periapical radiolucencies at the 1-year review without clinical symptoms. Teeth requiring RCT were found to have required longer periods in orthodontic bands prior to a definitive pulp diagnosis (P < .05).

Conclusion

A step-by-step approach by using orthodontic banding to monitor pulp status may reduce the incidence of RCT required through definitive coronal coverage restorations for cracked teeth with reversible pulpitis.

正畸带环和冠状覆盖后可逆性牙髓炎裂纹牙的牙髓存活率 - 一项为期一年的前瞻性队列研究。
导言:这项前瞻性研究的目的是调查患有可逆性牙髓炎的裂缝牙齿在使用正畸带进行初步稳定后,再进行冠状覆盖修复的1年牙髓存活情况:这项前瞻性研究的目的是调查患有可逆性牙髓炎的裂隙牙在使用正畸带进行初步稳定后,再进行冠状覆盖修复的1年牙髓存活率:方法:共招募了 125 名患有可逆性牙髓炎的裂隙牙患者。收集术前患者和牙齿数据。在正畸带中期确定牙髓诊断后,进行冠状覆盖修复。采用 Cox 和逻辑回归分析评估可能的预后因素,并将正畸带环期间牙髓稳定的初始时间与最终结果联系起来。牙髓存活率是通过临床和放射学检查结果确定的:对 166 颗裂开的牙齿进行了为期 1 年的随访。根据临床和放射学检查结果,发现有 81 颗牙齿(76.4%)的牙髓存活。在 25 颗失败的牙齿中,11 颗(44%)需要在正畸带阶段进行根管治疗,10 颗(40%)需要在冠状覆盖修复过程中或修复后进行根管治疗。有四颗牙齿(16%)在一年复查时偶然发现根尖周有放射线,但没有临床症状。需要进行RCT检查的牙齿在明确牙髓诊断之前需要较长的正畸带(p结论:通过使用正畸带监测牙髓状态的逐步方法,可以减少对患有可逆性牙髓炎的裂隙牙进行最终冠覆盖修复时所需要的RCT的发生率。

期刊介绍: The Journal of Endodontics, the official journal of the American Association of Endodontists, publishes scientific articles, case reports and comparison studies evaluating materials and methods of pulp conservation and endodontic treatment. Endodontists and general dentists can learn about new concepts in root canal treatment and the latest advances in techniques and instrumentation in the one journal that helps them keep pace with rapid changes in this field.
