The Epiphany-Resilon combination (group 3) was not superior to that of the AH Plus-gutta percha combination (group 1).

As emergency treatments for teeth having signs of irreversible pulpitis, pulpotomy, partial pulpectomy and total pulpectomy were comparable with respect to relieving clinical symptoms. Pulpotomy may be preferred because it requires significantly less time and is a simple technique that relieves symptoms quickly and effectively.

The use of BisCem and All Bond SE/Duo-Link combination with their simplified application procedures may be considered an alternative to the currently used systems for luting glass-fibre posts in root canal.

BackgroundTo evaluate the incidence of flare-ups and identify the risk factors including age, gender, tooth type, number of root canals, initial diagnosis, the type of irrigation regimen, treatment modality and the number of visits, in patients who received root canal treatment from January 2002 to January 2008.MethodsRecords of 1819 teeth belonging to 1410 patients treated by 1 endodontics specialist during 6-year period were kept. Patient, tooth, and treatment characteristics were evaluated and the relationships between these characteristics and flare-ups were studied. Statistical analysis was carried out by using Pearson Chi-square test, Fisher’s Exact test, and Binary Logistic regression analyses.ResultsThe incidence of flare-ups was 59 (3.2 %) out of 1819 teeth that received endodontic therapy. Pulpal necrosis without periapical pathosis was the most common indication for flare-up (6 %) (p < 0.01). Teeth undergoing multiple visits had a higher risk of developing flare-ups compared to those with single appointments (OR: 3.14, CI: 1.414–7.009, p < 0.01). There were also no statistically significant differences in the incidence of flare-ups regarding to age, gender, tooth type, number of root canals, treatment modality, and the irrigation solutions that used during the treatment.ConclusionsThe incidence of flare-up is minimal when teeth are treated in one visit. Absence of a periapical lesion in necrotic teeth is a significant risk factor for flare-ups.

The effects of EV, PIPS, and CSI on debridement efficacy, smear layer removal, and dentinal tubule penetration were almost comparable. TotalFill BC showed superior tubular penetration than AH Plus.

• Intentional replantation after repairing fractured fragments with an adhesive resin extraorally is a treatment option. • Long-term follow-up is necessary to evaluate the outcome of this technique.
