Perbedaan daya larut tiga minyak esensial terhadap siler bioceramic (kajian pada minyak eukaliptus (eucalyptus globulus), minyak jeruk manis (citrus sinensis), dan minyak jeruk limau gedang (citrus paradisi)) (laporan penelitian)
L atar belakang: Pelarut guta perca berbahan dasar minyak esensial telah banyakditeliti karena sifatnya yang tidak toksik dan efektivitasnya yang menyerupaipelarut konvensional. Pelarut tersebut juga dapat digunakan untuk melarutkanberbagai macam siler endodontik. Siler berbahan dasar bioceramic merupakansalah satu jenis siler yang sedang popular, akan tetapi dinyatakan sulit untukdilarutkan. Tujuan: Untuk mengetahui perbedaan daya larut tiga minyak esensialyaitu minyak eukaliptus (Eucalyptus globulus), minyak jeruk manis (Citrussinensis), dan minyak jeruk limau gedang (Citrus paradisi) terhadap silerbioceramic. Metode: Tiga puluh dua cetakan silindris stainless steel dengan tinggi1,5 mm dan diameter internal 8 mm dibagi menjadi tiga kelompok berisi sepuluhcetakan dan satu kelompok dengan dua cetakan untuk kontrol negatif. Tiap cetakandiisi siler bioceramic dan dimasukkan ke inkubator untuk mengeras. Setelah 72jam, siler ditimbang berat awal lalu direndam selama satu menit dalam satu mililiterpelarut. Siler dimasukkan ke inkubator selama 24 jam agar kering dan ditimbangkembali untuk mendapatkan berat akhir. Selisih dari berat siler dikalkulasikan dandianalisis menggunakan ANOVA satu jalan. Hasil: Analisis statistik dari selisihberat siler yang direndam dalam tiga pelarut minyak esensial memberikan nilaisignifikansi P > 0,05 antara kelompok pelarut. Kesimpulan: Daya larut ketigaminyak esensial terhadap siler bioceramic tidak memiliki perbedaan bermakna.
B ackground: Essential oil-based gutta-percha solvents have been extensivelystudied due to its non-toxicity and effectiveness that is similar to conventionalsolvents. These solvents can also be used to remove different types of endodonticsealers. Bioceramic-based sealer is popular nowadays. However, it was stated to bedifficult to dissolve. Objective: To know the difference between the efficacy ofeucalyptus oil (Eucalyptus globulus), sweet orange oil (Citrus sinensis), andgrapefruit oil (Citrus paradisi) as bioceramic sealer solvents. Methods: Thirty-twostainless steel cylindrical molds with 1.5 mm in height and 8 mm in internaldiameter were divided into three groups of ten molds each and a group of two moldsfor negative control. Each mold was filled with bioceramic sealer and placed insidean incubator to set. After 72 hours, the sealer was weighed to obtain initial weightand immersed for one minute in one milliliter of solvent. The sealer was placedinside an incubator for 24 hours to dry and weighed once more to get the finalweight. The difference in the weight was calculated and analyzed using one-wayanalysis of variance (ANOVA). Results: Statistical analysis of the difference inweight of the sealer immersed in three essential oil solvents gave a significancevalue of P > 0.05 between the solvent groups. Conclusions: There is no significantdifference between the efficacy of the three essential oils as bioceramic sealersolvents.
