PERBEDAAN PENGARUH PERENDAMAN RESIN KOMPOSIT NANOHYBRID PADA LARUTAN TEH ROSELLA (HIBISCUS SABDARIFFA L.) DENGAN MINUMAN BERWARNA BERKARBONASI (SODA) TERHADAP TERJADINYA DISKOLORASI

The increasing awareness of aesthetic values in society influences individuals when choosing dental restorative filling materials. A commonly used restorative filling material is composite resin. This study used nanohybrid composite resins, this is because nanohybrid composite resin has very small particle size, allowing for excellent polishability and reducing food retention. Nanohybrid composite resins also exhibits better hardness compared to other composite restorative materials. On the other hand, nanohybrid composite resin has the property that easily absorbing fluids, potentially leading to discoloration. Methods : This study is a true experiment using the prettest- posttest group design method. The study used 27 sampels of nanohybrid composite resin, specifically Filtek Z250 XT with 3 treatment groups, namely roselle tea (hibiscus sabdariffa l), carbonated drinks (soda) and aquadest as a negative control. Results : base on the results of the study indicate a significant color change (p<0,05) in nanohybrid composite resin after immersion in three treatment groups: immersion in roselle tea (hibiscus sabdariffa l) and carbonated drinks (soda). Additionally, it was found that soda had e higher impact on discoloration in nanohybrid composite resin compared to roeselle tea Conclusions : that soda had e higher impact on discoloration in nanohybrid composite resin.
