Evaluation of Bone Healing After Obturation With Dia-Root Bio Sealer (Calcium Silicate-based Sealer CSBS) Using Three Obturation Techniques (CSBS)

2026年7月4日 更新者：Omnia Saber、Ain Shams University

Evaluation of New Heat-Resistant Calcium Silicate- Based Sealer Using Different Obturation Techniques (In-Vitro and In-Vivo Study)

The study aims to evaluate the efficiency of using a Calcium silicate-based sealer (CSBS) with different obturation techniques in treating root canals with apical periodontitis in single visit.

Evaluating:

  1. Postoperative healing.
  2. Preoperative, postoperative pain and frequency of analgesic intake.

描述

Inclusion Criteria:

  • Medical condition: Medically free patients.
  • Age: Ranging from 20-50 years old
  • Gender: Male and female patients
  • Teeth: Patients with mandibular permanent mature molar(s) diagnosed with necrotic pulps and with apical periodontitis (asymptomatic, symptomatic apical periodontitis, or chronic periapical abscess), with at least one of the roots showing radiographic evidence of periapical lesion.
  • Preoperative radiographic (CBCT) lesion size should range from 2 - 4 mm.
  • Patients who fulfill these criteria, agree to participate, and sign the informed consent

Exclusion Criteria:

  • Participants with generalized periodontal disease, and those who are pregnant, breastfeeding, or have any systemic disease.
  • Teeth diagnosed with immature apices, root resorption, or non-restorable.
  • Patients in which the clinical assessment necessitates multiple-visits treatment, such as those with signs and symptoms of acute or diffuse infection.
  • Patients who had pre-treatment antibiotic therapy or analgesics and within 7 days.
  • Patients who fail to complete their final restoration postoperatively.
  • Patients who will refuse to sign the informed consent.
  • Root canals requiring apical preparation larger the #40.

武器和干预

参与者组/臂
干预/治疗
实验性的：Single cone (SC) technique group
Conventional Root canal treatment followed by obturation with the Dia-Root Bio sealer using the Single cone technique
设备：Dia-Root Bio Sealer
The sealer will be delivered in the canals with the provided intracanal tips inserted three millimeters from the WL and back filling until the orifice. The pre-fitted master cone will be inserted with slight up and down motion before reaching the WL.
其他名称：
  • Calcium silicate-based sealer
  • CSBS
  • MTA-based bioceramic root canal sealer
程序：Single cone (SC) Obturation technique
Filling the prepared root canal with the master cone and the CSBS. Then cutting the excess gutta percha from the root canal orifice
其他名称：
  • Root canal compaction
  • Root filling techniques
实验性的：Warm vertical compaction (WVC) technique group
Conventional Root canal treatment followed by obturation with the Dia-Root Bio sealer using the warm vertical compaction technique
设备：Dia-Root Bio Sealer
The sealer will be delivered in the canals with the provided intracanal tips inserted three millimeters from the WL and back filling until the orifice. The pre-fitted master cone will be inserted with slight up and down motion before reaching the WL.
其他名称：
  • Calcium silicate-based sealer
  • CSBS
  • MTA-based bioceramic root canal sealer
程序：Warm Vertical compaction (WVC) technique
After placing the CSBS intside the RC, the cone will be packed down till 4 mm from the apex for 4 seconds cycles. Then the apical GP will be condensed using pluggers previously fitted inside the canal. Canals will be backfilled with 180C temperature setting. The tip will be placed into the root canal against the apical gutta-percha for 5 s before extruding the gutta-percha on increments. The middle and coronal thirds will be condensed using pre-fitted pluggers.
其他名称：
  • Root canal filling
  • Root canal obturation
有源比较器：Cold lateral compaction (CLC) technique group
Conventional Root canal treatment followed by obturation with the Dia-Root Bio sealer using the cold lateral compaction technique
设备：Dia-Root Bio Sealer
The sealer will be delivered in the canals with the provided intracanal tips inserted three millimeters from the WL and back filling until the orifice. The pre-fitted master cone will be inserted with slight up and down motion before reaching the WL.
其他名称：
  • Calcium silicate-based sealer
  • CSBS
  • MTA-based bioceramic root canal sealer
程序：Cold lateral condensation (CLC) technique
After placing the CSBS inside the root canal, the master GP cone will be laterally condensed with a pre-selected spreader inserted 2-4 mm from the WL and accessory GP cone will be placed in the provided space by the spreader. This process will be repeated until 1 mm from the canal orifice. Excess GP will be cut at the orifice with a heat carrier and lightly packed vertically with a plugger.
其他名称：
  • Root canal filling
  • Root canal obturation
  • Gold standard root canal filling technique

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Success of healing and healing rate of the periapical lesion after one year
大体时间：6 and 12 months postoperatively
Periapical bone healing will be evaluated using Cone Beam Computed Tomography (CBCT) images scored according to the CBCT Periapical Index (CBCT-PAI). Success is defined as a CBCT-PAI score of 0 (healthy) or a significant reduction in the volumetric size of the periapical radiolucency compared to the preoperative baseline
6 and 12 months postoperatively

次要结果测量

结果测量
措施说明
大体时间
Change in Postoperative Pain Intensity
大体时间：Preoperative (Baseline) and 72 hours postoperative
The change in patient-reported pain intensity from baseline. Pain is evaluated using a 0 to 100 mm Visual Analog Scale (VAS), where 0 represents 'no pain' and 100 represents 'the worst imaginable pain' Patients will be asked not to use analgesic medication after treatment until needed. If necessary, the patient will be instructed to record pain score before analgesic administration and record the dose and frequency of intake (by hour) of the analgesic and to submit this information after 72 h.
Preoperative (Baseline) and 72 hours postoperative
