Abstract

Background: Dental composite composed of natural filler is a trend nowadays. Silk fiber, Bombyx mori L., is one of the natural fibers that have good microhardness (66 VHN) and has a potency to become a renewable natural filler. This research aimed to determine microhardness differences of silk fiber composite B. mori L., and nanofiller composite resin as a gold standard.Method: A quasi-experimental laboratory using composite resin with silk fiber B. mori L., as a natural filler; nanofiller composite Z350 XT flowable (3M ESPE, USA) as a positive control and no-filler composite as a negative control. Four cylindrical specimens per group were made (d=3mm, h=6mm). Microhardness tests were done with Vickers hardness tester (Shimadzu, Japan). Indentation of 100 grams for 20 seconds.Result: There were significant differences in the natural filler, nanofiller group (positive) control and no-filler composite (negative control). Based on the Kruskal Wallis test result, there was a significant difference in microhardness (p=0.024). The highest microhardness was nanofiller (115,2 VHN), silk fiber filler (109,4 VHN), and no-filler composite (32,2 VHN).Conclusion: Silk fiber Bombyx mori L., has shown the good potential of being a renewable natural filler (109,4 VHN) however lower than nanofiller composites.

Abstract

Background: The human body can self-repair. However, if the damage occurs excessively or reaches a critical defect, it requires material substitution to restore its shape and function. Tissue engineering is developed based on the principle of reconstructing damaged tissues due to critical defects to restore, maintain, and repair damaged tissues or organs by applying three main components: scaffolds, signaling molecules, and cells. This study aims to investigate the ability of synthetic coral scaffold incorporated with Platelet Rich Plasma in bone remodeling after tooth extraction. Method: This study was conducted as in vivo experimental laboratory study with a post-test control group design. The 48 male Rattus norvegicus rats were divided into 4 treatment groups. Firstly, the rats’ teeth were extracted, then, on the tooth extraction area, it was treated with povidone-iodine (control group), curaspon, scaffold only, and scaffold-incorporated Platelet Rich Plasma. Result: The results of the Kruskall-Wallis test showed no significant difference (p > 0.05) between the four treatment groups. articleConclusion: The PRP-incorporated synthetic coral scaffold had the highest score of collagen formation density and significantly accelerated collagen formation in the bone remodeling process compared to other treatment materials.
