Pengaruh Lama Perendaman Bahan Gigi Tiruan Jembatan Sementara Resin Akrilik Swapolimerisasi dan Bis-Acryl dalam Larutan Kunyit Asam terhadap Stabilitas Warna

Abstract

A temporary bridge is a denture that aims to replace missing teeth temporarily until a permanent bridge is installed. The most commonly used temporary denture materials are self-polymerized acrylic resin (SVA) and bis-acryl. The wearing time is highly dependent on the procedure for making a permanent bridge. Color stability is a very important characteristic of temporary bridge materials. Indonesians like to consume herbal medicine, one of which is turmeric and tamarind herbal medicine. The main ingredient of this herbal medicine is turmeric with additional ingredients, namely tamarind. The curcumin dye in turmeric and tamarind is feared to affect the color stability of temporary bridge materials. The purpose of this study was to determine the effect of soaking and the difference in the effect of soaking temporary bridge materials using self-polymerized acrylic resin and bis-acryl on color stability. The study design was an experimental laboratory pretest & post-test control group design with 40 cylindrical samples with a diameter of 15 ± 0.5 mm and a thickness of 2 ± 0.5 mm in a turmeric and tamarind solution and artificial saliva as a control group. The color stability of the samples was then tested using a colorimeter. Data were analyzed using one-way ANOVA and LSD. There was a significant difference in the effect of immersion between the RAS and bis-acryl groups across all immersion groups (p = 0.0001 (p < 0.05)), and there was a significant difference in the effect of immersion between the RAS and bis-acryl groups across all immersion groups (p = 0.0001 (p < 0.05)). Self-polymerizing acrylic resin is preferred for patients as a temporary bridge material because it is more resistant to color change than bis-acryl.
