Apical Periodontitis, Irreversible Pulpitis
Conditions
Brief summary
The purpose of this study was to evaluate the clinical and radiological outcomes of iRoot SP as a root canal sealer in comparison with AH Plus sealer within 1-year follow up.Patients needing root canal treatment were enrolled and allotted into either iRoot SP group or AH Plus arm randomly. After root canal shaping and cleaning, the teeth were obturated according to their arms. Assessment of postoperative pain was done 1 week after root canal obturation using visual analog scale. After 1-year follow-up, clinical and radiographic evaluations were carried out. Statistical analysis at P \< 0.05 was conducted to measure difference between the arms.
Interventions
PROCEDURERoot canal sealer
Patients who required root canal therapy were enrolled and allotted into either iRoot SP arm or AH Plus arm randomly.For Test Arm: iRoot SP was used as a sealer. Obturation was performed with Gutta-percha cones and root canal sealer by continuous-wave condensation technique. For Control Arm: AH Plus was used as root canal sealer. The same steps were followed for obturation as in Test Arm.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Radiographical assessments | 1 year after root canal therapy | The periapical status was assessed in the radiographs.Teeth with complete restitution of the periodontal contours were judged as healed. Teeth with a clearly decreased size of the periapical radiolucency were judged as healing. Teeth with unchanged, increased, or new periapical radiolucency were judged as failed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical assessments | 1 year after root canal therapy | The root filled tooth was considered clinically successful if there was absence of clinical sign or symptom such as spontaneous pain, sensitivity to percussion or palpation, abnormal mobility, signs of pathology like abscess or sinus tract. |
| Postoperative Pain Evaluation | 1 week after root canal therapy | Pain was evaluated by using a visual analogue scale (VAS) made of a 10 cm line, where 0 = no pain and 10 = unbearable pain. |
