Background: Achieving a reliable seal in root canal obturation is essential for the success of endodontic treatment. Despite the availability of multiple techniques, the comparative sealing abilities of these methods remain a topic of investigation, particularly in permanent molars.
Materials And Methods: This study involved 60 extracted permanent molars, divided randomly into three groups: Group A (lateral compaction), Group B (thermoplasticized gutta-percha), and Group C (single cone). After instrumentation and obturation, the sealing ability was assessed using a dye penetration method. Arbitrary values were assigned to quantify the extent of dye penetration.
Results: The mean dye penetration values were as follows: Group B (thermoplasticized gutta-percha) had the lowest penetration (2.1 ± 0.3 mm), followed by Group A (lateral compaction) (3.5 ± 0.4 mm), and Group C (single cone) exhibited the highest penetration (5.2 ± 0.6 mm).
Conclusion: In this study, thermoplasticized gutta-percha demonstrated superior sealing ability compared to lateral compaction and single cone techniques in permanent molars. These findings underscore the importance of selecting an effective obturation technique to ensure optimal seal integrity in root canal therapy.

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.
