Experimental: One vist group
All patients included in this treatment group will receive the complete endodontic treatment in a single visit.
Procedure: Root canal therapy in one visit
Patient was anesthetized with local anesthetic solutions, and the caries was removed. The tooth was isolated with rubber dam and access to pulp chamber was completed. Cleaning and shaping preparation was achieved with manual and rotatory endodontic instruments.The ideal working length was determined by an electronic apex locator and periapical radiography. Irrigation was performed with 5.25%NaOCl solution. The smear layer was removed by 10% citric acid. The cases were obturated with guta-percha cones using a lateral compaction filling technique as well as zinc oxide-eugenol-based root canal sealer. The teeth filled with a light-cured resin.
Active Comparator: Two-vist group
All patients included in this treatment group will receive treatment in two visits. The first will be done chemo mechanical root canal preparation, the placement of the intracanal medication the basis of calcium hydroxide and coronal sealing. Ten to twelve days later, this medication is removed and the root canal will be permanently filled.
Procedure: Root Canal Therapy in two-vist
The treatment protocol was the same as described for one visit group. In the first visit, after cleaning, shaping and smear layer removal, the root canals were medicated with a calcium hydroxide paste and sterile distilled water (1:1) and the pulp chamber was sealed with a minimum 3mm thickness temporary filling restoration. After 10-12 days, during the second visit, the medication was removed, and the cases were obturated with guta-percha cones using a lateral compaction filling technique as well as zinc oxide-eugenol-based root canal sealer. The teeth filled with a light-cured resin.
Other Name: Multiple-visit of root canal treatment
- Healing Rate of one- versus two-visit endodontic treatment [ Time Frame: Two years ]After completion of endodontic treatment in one or two visits, patients will be followed clinically and radiographically every 06 months for a minimum of two years to assess the prevention and repair of apical periodontitis.
- Postoperative pain of endodontic treatment [ Time Frame: 60 days ]Following the completion of endodontic treatment in one or two visits, patients receive a clinical record for home monitoring of postoperative pain and return to clinic to conduct a follow-up clinical and radiographic. Pain is assessed using a numerical scale for pain.
