Postoperative pain after single-visit root canal treatments in teeth with pulp necrosis - a prospective randomized multicenter clinical trial
- Conditions
- Chronic apical periodontitis
- Registration Number
- RBR-3r967t
- Lead Sponsor
- Pontifícia Universidade Católica do Paraná
- Brief Summary
Clinical and demographic data from the patients/teeth that constituted the sample of the current PRMCT and their respective statistical analyses are exposed in Table 4. Significative statistical differences among the groups were only observed considering tooth, periradicular status, and the incidence of overfilling (sealer extrusion) (P ? 0.00). Of 60 teeth of G3, 27 (45%) were first mandibular molars; meanwhile, in G1, G2, and G4, only 7 (11.7%), 8 (13.3%), and 5 (8.3%) first mandibular molars were present, respectively. Concerning periradicular status, in G1, 44 (73.3%) teeth showed AAP. In G2, G3, and G4, 12 (20%), 40 (66.7%), and 27 (45%) teeth presented AAP in that order. Sealer extrusion (overfilling) happened in only 3 (5%) teeth from G1. In G2, G3, and G4, this event did occur in 24 (40%), 14 (23.3%), and 26 (43.3%) teeth, respectively.
