The Aim Of This Study Was To Compare Fracture Resistance Of Roots Obturated With Totalfill BC Sealer Using Two Obturation Techniques.
Materials and Methods: Thirty Single-canal Extracted Mandibular Premolars Were Selected. The Crowns Were Removed And The Roots Were Prepared With Fanta Rotary System To Size 40 Taper 4 And Obturated With Totalfill Bioceramic Sealer. Roots Were Divided Into Two Groups According To Obturation Technique (n?= 15). Group I: Lateral Compaction Technique Was Used And Group II: Single Cone Technique Was Used. All Specimens Were Tested In A Universal Testing Machine As The Force At The Time Of Fracture Was Recorded In Newtons. Data Were Analyzed Using The One-way Analysis Of Variance.
Results: Showed That Group II Has Significantly Higher Values (419.5?34.9N) Than Group 1 (292.6?3.8N).
Conclusion: It Can Be Concluded That Single Cone Obturation With Bioceramic Sealer Has The Ability To Increase The Fracture Resistance Of Root Canals After Instrumentation, And Thus Reinforcing Endodontically Treated Teeth.
