Aim Of The Study: The aim of this study was to compare and evaluate the sealing ability of four root end filling materials mineral trioxide aggregate (MTA)-Plus, Biodentine, MTA (MTA Angelus) and glass ionomer cement (GIC) using fluid filtration method.
Materials And Methods: Forty-four extracted, human single-rooted teeth were collected. The crown of each tooth was decoronated 2 mm above the cementoenamel junction. Canals were negotiated, instrumented, obturated using lateral compaction method. The access cavities were sealed with Cavit. Root end resection and apical root end cavity preparations of 4 mm were made in each specimen. The selected roots were then randomly divided into four groups ( = 11) and restored as follows. Group 1 - GIC, Group 2 - MTA (MTA Angelus), Group 3 - Biodentine, and Group 4 - MTA Plus. The apical microleakage of each specimen was assessed using fluid filtration method at 72 h, 1 month and 3 months. Microleakage in each specimen was recorded in mm (millimeter) and converted to μl/min/cm HO.
Results: MTA Angelus showed least microleakage followed by Biodentine and MTA Plus. Least sealing ability was seen with GIC. There was statistically significant difference between all the materials at various time intervals.
Conclusion: MTA Angelus showed superior sealing ability as a retrograde filling material followed by Biodentine and MTA Plus.

Uncontrollable bleeding poses a significant risk of death and cost in wars, vehicle accidents, and first aid. Hence, in order to seal uncontrollable bleeding and promote wound healing, the Fe-driven chitosan quaternary ammonium salt self-gelling powder (QPF) was prepared using 5%QCS/AA/Fe with the 52.72 % ± 0.

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.
