Background:The occurrence of anosmia/hyposmia during novel Coronavirus disease 2019 may indicate a relationship between coincidence olfactory dysfunction and coronavirus .This study aimed to assess the frequency self-reported COVID-19 epidemic in Iran.Methods: This population-based cross sectional was performed through an online questionnaire from March 12 17, 2020.Cases all provinces Iran voluntarily participated this study.Patients completed 33-item patient-reported questionnaire,...
Abstract The purpose of this study was to compare the bond strength a new bioceramic sealer (EndoSequence BC Sealer) and AH Plus in presence or absence smear layer. Extracted single‐rooted human teeth were prepared randomly divided into four groups. In groups 1 3, root canals finally irrigated with 5.25% NaOCl layer not removed, but 2 4, 17% EDTA followed by order remove 2, obturated gutta‐percha/AH Plus, 3 obturation performed gutta‐percha/EndoSequence Sealer. Push‐out failure modes...
Abstract Purpose To evaluate the accuracy of a digital implant impression technique using TRIOS 3Shape intraoral scanner (IOS) compared to conventional techniques (pick‐up and transfer) in clinical situations. Materials Methods Thirty‐six patients who had two implants (Implantium, internal connection) ranging diameter between 3.8 4.8 mm posterior regions participated this study after signing consent form. reference models (RM) were fabricated by attaching copings intraorally, splinted with...
Abstract Aim This split‐mouth double‐masked randomized controlled clinical study evaluated the effectiveness of photoactivated disinfection ( PAD ) using light‐emitting diode LED as an adjunct in management patients affected by moderate to severe chronic periodontitis.

The penetration depth of irrigating solutions in dentinal tubules is limited; consequently, bacteria can remain inside after the cleaning and shaping root canal system. Therefore, new irrigation systems are required to increase tubules.A comparative study regarding sodium hypochlorite (NaOCl) solution using four methods, (1) conventional (CI), (2) smear layer removal plus (gold standard), (3) passive ultrasonic agitation (PUA) (4) Nd:YAG laser activated (LAI), took place on 144 extracted...
