Outcome of Root Canal Treatments Obturated With Calcium Silicate Based Sealers

Study Overview
=================
Brief Summary
-----------------
The clinical use of a flowable premixed calcium-silicate bioceramic sealer used in association with warm carrier-based/single-cone technique will be compared with epoxy resin-based sealer with carrier-based technique.

Detailed Description
-----------------
Healthy consecutive patients (n= 109) requiring 141 root canal treatments were enrolled in this study and divided in 3 groups (Group 1: Ceraseal + single cone cold technique n=47. Group 2: Ceraseal + Carrier-based technique n=47. Group 3 AH Plus + Carrier based technique n=47). Periapical X-rays were taken preoperatively, after root canal filling and after 6, 12 and 24 months. Two evaluators blindly assessed the Periapical Index (PAI) and sealer extrusion in the 3 groups (k =0.90). Healing rate and survival rate were also analysed. Chi square tests was used to analyse significant differences among the groups. Multilevel analysis was performed to analyse the factors associated to healing status and survival status.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Premixed Sealer + Single cone<br>Premixed flowable hydraulic calcium silicate sealer was applied with a a K File #15 that was inserted into the canal to reach the WL - 3mm and gently moved around the root canal walls. Then, gutta-percha points were gently inserted at the WL -0.5mm and compacted with lateral condensation/vertical condensation. | Other: root canal filling with Ceraseal sealer<br>* root canal filling with Ceraseal sealer<br>|
| Experimental: Premixed Sealer + Thermafil<br>Premixed bioceramic sealer was applied and previously described. Pre-heated carrier was inserted in the canal at WL-0.5mm. The carrier excess was removed with a Thermacut bur. | Other: root canal filling with Ceraseal sealer<br>* root canal filling with Ceraseal sealer<br>|
| Other: Sealer + Thermafil<br>Epoxy-resin-based sealer was mixed and immediately inserted into the root canal using a K File #15. Pre-heated carrier was inserted in the canal at WL -0.5mm. The carriers excess was removed with a bur. | Other: root canal filling with Ceraseal sealer<br>* root canal filling with Ceraseal sealer<br>|
