Avulsed teeth that are replanted dried are more prone to loss. Recent tissue engineering studies focus onfabrication of various cell delivery systems to improve the overall prognosis of such teeth. To evaluate this newcell transplant method, we initially aimed at designing of PRF scaffold and determining BMMSCs viabilityand function on the fabricated scaffold. To test this concept in-vitro, hum...
Several studies have aimed to evaluate the characteristics of hard dental tissues from animal species in order to adequately substitute the usage of human teeth. The purpose of this study was to evaluate the radiodensity of enamel and dentin of human, bovine and swine teeth. Five specimens of 2 mm in thickness were obtained from human, bovine and swine teeth and the radiographic images were tak...

Introduction: Root canal obturation aims at sealing the root canal system to prevent re-contamination of canal and periapical space. Presence of moisture in canal before obturation may posit a negative effect on the quality of canal sealing. Therefore, this study was conducted to investigate the effect of canal contamination with saliva on apical microleakage. Methods: In this laboratory study...

1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
Background and Objective: Relining fiber posts with flowable composites is a procedure used for strengthening the weak walls of endodontically treated teeth. The aim of this study was to evaluate the effect of relining fiber posts with two types of flowable composites on the fracture resistance of the endodontically treated teeth. Materials and Methods: In this laboratory experimental study, 3...
Sixty intact, non-carious and unrestored teeth extracted due to periodontal disease were used to determine the most effective method of sterilisation. The teeth were divided into six groups, each containing 10 teeth. Group 1 teeth were immersed in 10% formalin for seven days, group 2 teeth were immersed in 3% hydrogen peroxide for seven days, group 3 teeth were immersed in 2.6% sodium hypochlor...
