Outcomes of Conventional Root Canal Treatment Compared to Regenerative Endodontics, and Cleaning and Shaping Only in Mature Upper First Premolars

2026年8月20日 更新者：Maram Reda Afifi、Ain Shams University

The Effect of Regenerative Endodontic Procedures and Only Cleaning and Shaping on The Outcome of Adult Mature Permanent Necrotic Teeth: A Randomized Clinical Trial

It was to compare clinically between the success of the primary endodontic treatment, regeneration, and only cleaning and shaping in necrotic mature first premolars with apical periodontitis

详细说明

a- Fifty four patients were enrolled and screened for eligibility b- Participants were randomly assigned to three groups (n=18 per group) i- Group [CRCT]: Conventional root canal treatment (n=18) ii- Group [REP] : Regenerative endodontic treatment (REP) (n=18), cell homing technique was used , and MTA was placed 3mm into the canals , the access was sealed by light cured glass ionomer then composite iii- Group [C.S]: Only cleaning and shaping (n=18) the same steps of REP but without bleeding induction and MTA was placed 3mm into the canals , the access was sealed by light cured glass ionomer then composite

武器和干预

参与者组/臂
干预/治疗
无干预：Control group
conventional endodontic treatment, the canals were filled by conventional gutta percha with proper coronal seal
有源比较器：Regeneration group
Cell homing via bleeding induction was done, MTA was applied into the canals at a depth of 3mm, and the access was sealed by light-cured glass ionomer, then composite restorations were placed
其他：cell homing
it is done by bleeding induction into the canals
实验性的：Cleaning and shaping only group
Aseptic techniques were used while using the irrigation activation technique to enhance the irrigation effects, after then MTA was applied into the canals at a depth of 3mm, and the access was sealed by light-cured glass ionomer then composite restorations were placed to ensure proper coronal seal
程序：Cleaning and shaping only
proper canal disinfection and mechanical instrumentation followed by proper coronal seal

主要结果指标

结果测量
措施说明
大体时间
Resolution of the clinical and radiographic sign and symptoms
大体时间：follow ups 3, 6 12 months

Clinically, no pain upon percussion or palpation, and no sinus tracts. Signs of radiographic bone healing it is going to be recorded as a yes/ no answer. No sign and symptoms= no pain upon percussion, palpation, and no sinus tract was observed Yes, there are signs and symptoms= that one or more of these criteria will be present [ pain upon percussion, presence of a bulge upon palpation, sinus tract exists] Radiographic healing will be assessed by 2 ways.

  1. Qualitative test by using the Periapical Index Score; score 1 indicates bone healing, and score 5 indicates Severe apical periodontitis, with exacerbating features
  2. Quantitative assessment measured the percent of lesion reduction using ImageJ software to measure the area of the lesion preoperatively and at follow-ups. This rule will be used: [preoperative area - postoperative area] / preoperative area = ... X100= ..%
follow ups 3, 6 12 months

次要结果测量

结果测量
措施说明
大体时间
restoring of the pulp vitality which will be recorded by electric pulp tester
大体时间：3,6,12 months
The reading at each follow-up will be a yes/ no answer Yes, there is sensation if the patient feels tingling while using the electric pulp tester No, no sensation if the patient didn't feel the tingling
3,6,12 months
