The Effect of Two Different Root Canal Sealers on Postobturation Pain in Single-Visit Root Canal Treatment: A Prospective Clinical Randomized Study- Part 1, Influence of Resin-based and Mineral Trioxide Aggregate-based Sealers on Treatment Outcome After Two-year Follow-up in Mandibular Molar Teeth With Asymptomatic Irreversible Pulpitis-Part 2
The Effect of Two Different Root Canal Sealers on Postobturation Pain in Single-Visit Root Canal Treatment: A Prospective Clinical Randomized Study- Part 1, Influence of Resin-based and Mineral Trioxide Aggregate-based Sealers on Treatment Outcome After Two-year Follow-up in Mandibular Molar Teeth With Asymptomatic Irreversible Pulpitis-Part 2
Post-obturation pain evaluation(Part 1):
One hundred asymptomatic mandibular molar teeth with vital pulp were randomly assigned into two groups according to the sealer used MTA Fillapex (Angelus Odontologica Industries SA, Londrina, PR, Brazil) or AH Plus (Dentsply Sirona, Ballaigues, Switzerland) sealer. WaveOne Gold instruments were used for root canal preparations in both groups. Root canals were obturated with the manufacturer advised own gutta-percha points of preparation technique and MTA Fillapex was used in the first group and AH Plus was used in the second group as a root canal sealer. Postoperative pain at 6, 12, 24, 48, 72 hours, 4, 5, 6, 7, and 30 days after root canal treatment was measured with the Numerical Rating Scale (NRS), and patients were informed to record the number of analgesics they used during these time periods.
Clinical and radiological outcome evaluation(Part 2):
Patients were recalled for clinical and radiographic examinations at 12 and 24 months postoperatively. The clinical outcome was determined as success or failure according to objective evaluation of symptoms of inflammation or infection. In clinical examination at follow-up appointments, swelling, pain, sinus tract, tenderness to percussion, and/or palpation test, periodontal probing depths were determined and recorded. The radiographic outcome was evaluated and classified according to the Strindberg criteria. Teeth with a normal contour, width, and structure of the periodontal ligament were considered as"successful" and teeth with a widened periodontal contours or a new periapical radiolucency were considered as "failed". Additionally, the other parameters (age, gender, tooth number, apical gutta level) on treatment success were examined.
This randomized clinical trial aimed to evaluate and compare the effect of MTA-based bioceramic and resin-based sealers on the incidence and intensity of post-obturation pain and clinical and radiological outcome after two-year follow-up in asymptomatic vital molar teeth in single-visit root canal treatment. One hundred asymptomatic mandibular molar teeth with vital pulp were randomly assigned into two groups according to the sealer used MTA Fillapex (Angelus Odontologica Industries SA, Londrina, PR, Brazil) or AH Plus (Dentsply Sirona, Ballaigues, Switzerland) sealer. WaveOne Gold instruments were used for root canal preparations in both groups. Root canals were obturated with the manufacturer advised own gutta-percha points of preparation technique and MTA Fillapex was used in the first group and AH Plus was used in the second group as a root canal sealer.
Post-obturation pain evaluation(Part 1):
Postoperative pain at 6, 12, 24, 48, 72 hours, 4, 5, 6, 7, and 30 days after root canal treatment was measured with the Numerical Rating Scale, and patients were informed to record the number of analgesics they used during these time periods. The Mann-Whitney U test was used to compare the postoperative pain and the analgesic use between the two groups according to NRS scores. The relationship between the number of analgesics used and the total NRS values were analyzed by Spearman Correlation Analysis. Evaluation of NRS scores at all time points for each group was done by Friedman Two-Way Analysis of Variance Test.
Clinical and radiological outcome evaluation(Part 2):
Patients were recalled for clinical and radiographic examinations at 12 and 24 months postoperatively. The clinical outcome was determined as success or failure according to objective evaluation of symptoms of inflammation or infection. In clinical examination at follow-up appointments, swelling, pain, sinus tract, tenderness to percussion, and/or palpation test, periodontal probing depths were determined and recorded. The radiographic outcome was evaluated and classified according to the Strindberg criteria. Teeth with a normal contour, width, and structure of the periodontal ligament were considered as "successful" and teeth with a widened periodontal contours or a new periapical radiolucency were considered as"failed". Additionally, the other parameters (age, gender, tooth number, apical gutta level) on treatment success were examined. All of the pairwise comparisons between the groups at 1st and 2nd year were done by chi-square test (Fisher exact test). Pearson's chi-square test was used to evaluate the age, gender of the patients and tooth types between the groups
