Extraction and Characterization of Nanoparticles from Snakehead Fish (Channa striata) Bone as a Pulp Capping Material

This study aimed to extract nanoparticles from the bones of the snakehead fish (Channa striata) and evaluate their physicochemical characteristics.

High-speed blending and ball milling techniques were employed for the extraction process. The morphological features, crystalline structure, and elemental composition of the resulting nanoparticles were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray fluorescence for both qualitative and quantitative analysis.

The results indicated that fish bone milled for 7 hours at 600 rpm produced an average particle size of 38.68 nm. The calcium oxide and phosphate contents were found to be 62.14% and 35.96%, respectively. The calcium phosphate compound derived from the fish bone exhibited 100% crystallinity.

Nanoparticles from the bones of the snakehead fish (Channa striata) have a significant profile to be used for vital pulp therapy.

The presence of calcium and phosphorus elements, along with the distinct diffraction pattern of hydroxyapatite, as well as the particle morphology and size, suggests that this compound holds potential as an alternative material for pulp capping.
