Perbedaan Pembentukan Dentinal Bridge antara Pasta Kalsium Fosfat Tulang Ikan Pora-Pora dengan Kalsium Hidroksida setelah Perawatan Direct Pulp Capping pada Molar Satu Maksila Tikus Wistar

Abstract

Caries is the most common dental problem experienced by people. Caries that reaches the pulp or reaches the de ntin but after excavation causes the pulp to be exposed, direct pulp capping is required. Apart from calcium hydroxide as the gold standard material, calcium phosphate compounds can also be used as pulp capping materials which can be extracted from fish bo nes. This study aims to determine the differences in odontoblast cell layers and dentinal bridge formation between pore fish bone calcium phosphate paste and calcium hydroxide. The type of research carried out was an in vivo experiment on Wistar rats with the research design being a post test only control group design. The samples in this study were 25 maxillary molar teeth of Wistar rats which were divided into 5 experimental groups and observed for 30 days. The data obtained was processed using the Kruska l Wallis test then continued with Mann Whitney. The results of the study showed that there were significant differences in the formation of the odontoblast cell layer and dentinal bridge between pora pora fish bone calcium phosphate paste and calcium hydro xide. Calcium hydroxide shows better results compared to calcium phosphate paste with concentrations of 25%, 50%, 75%. Paste with 75% concentration can stimulate the formation of odontoblast cell layer and dentinal bridge , but it is not perfect and pastes with 25% and 50% concentration cannot form odontoblast cell laye r and dentinal bridge.
