Introduction: Microleakage continues to be a main reason for failure of root canal treatment where the challenge has been to achieve an adequate seal between the internal structure and the main obturating material. The objective of this study is to compare the sealing ability of 3 newer obturating materials GuttaFlow, Resilon/Epiphany system (RES) and Thermafil, using silver nitrate dye and observing under stereomicroscope.
Methodology: Thirty single rooted teeth were divided into following groups. Group I : GuttaFlow ;Group II : Resilon /Epiphany sealer Group III : Thermafil with AH-Plus sealer. Teeth were decoronated and instrumented with profile rotary system and obturated with specified materials. Apical seal was determined by dye penetration method using silver nitrate. Then the specimens were transversely sectioned at each mm till 3 mm from the apex. Dye leakage was determined using stereomicroscope. Statistical analysis of the results was performed using Kruskall-Wallis test.
Results: The results showed that Group II i.e., Resilon with Epiphany sealer showed the least amount of microleakage when compared to Group I i.e., GuttaFlow and Group III i.e., Thermafil with AH-plus sealer.
Conclusion: Based on the results of this study it can be concluded that RES had higher sealing ability followed by Thermafil and GuttaFlow in vitro but further studies have to be carried out to make a direct correlation between these results and invivo situation.

Three endophytic strains, Phomopsis sp., Fusarium proliferatum, and Tinctoporellus epimiltinus, isolated from various plants in the rainforest of the Philippines, were investigated regarding their ability to repress growth of the pathogenic fungus Colletotrichum musae on banana fruits causing anthracnose disease. An in vitro plate-to-plate assay and an in vivo sealed box assay were conducted, using commercial versus natural potato dextrose medium (PDA).

Soft tissue integration (STI) around dental implants determines their long-term success, and the key is to immediately construct a temporary soft tissue-like barrier to prevent bacterial invasion after implantation and then, promote STI. In response to this need, an injectable multi-crosslinked hydrogel (MCH) with abilities of self-healing, anti-swelling, degradability, and dry/wet adhesion to soft tissue/titanium is developed using gallic acid-graft-chitosan, oxidized sodium alginate, gelatin, and Cu with water and borax solution as solvents, whose properties can be controlled by adjusting its composition and ratio. MCH can not only immediately build a sealing barrier to block the bacterial invasion in the oral simulation environment but also deliver outstanding antibacterial efficacy through the synergism of trapping bacteria and releasing bactericidal agents such as chitosan, gallic acid, aldehyde, and Cu.

Purpose: This study assessed the microgap width and adhesion of three bacterial species in four dental implants with different interlocks under four screwing torques.
Materials And Methods: Ten samples of four implant systems with various interlockings, including full-hexagonal (FHI), cylindrical-conical trilobe-index (TLI), Morse-taper with octagon terminal index (OI), and hexagonal interlock (slip-fit) (HI-SF), were used. The abutments were screwed to the fixtures under torques of 10, 20, 30, and 40 Ncm.
