Abstract

Cuka apel adalah minuman kesehatan yang terdiri atas fenol, asam dan komponen lainnya. Komposisi ini dapatmempengaruhi sifat resin akrilik heat cured. Resin akrilik heat cured secara klinis dapat digunakan sebagaibahan gigi tiruan. Resin akrilik dapat menyerap air sehingga menyebabkan ketidakstabilan dimensi basis gigitiruan. Penyerapan air dipengaruhi oleh jenis larutan dan lama perendaman. Tujuan penelitian ini adalah untukmengetahui efek lama perendaman resin akrilik heat cured dalam cuka apel terhadap perubahan dimensi.Sepuluh spesimen penelitian berbentuk disc dengan diameter 50 ± 1 mm dan ketebalan 0,5 ± 0,1 mmdikeringkan dalam desikator pada temperatur 37oC kemudian berat awal spesimen (W1) diukur menggunakankaliper (L) dan neraca analitik. Spesimen kemudian direndam dalam cuka apel pada 37oC selama 1, 3, 5 dan 7hari. Spesimen dikeringkan selama 15 detik dan berat spesimen tercatat (W2). Data dianalisis denganmenggunakan repeated Anova dan post hoc pairwaise comparisons. Hasil penelitian menunjukkan lamaperendaman di dalam cuka apel dapat menyebabkan perubahan dimensi resin akrilik heat cured secara bermakna(p< 0,05). Ada perbedaan yang bermakna antara perubahan dimensi setelah 1 hari dengan 3, 5, 7 hari (p< 0,05),tetapi tidak ada perbedaan yang bermakna antara 5 hari dengan 7 hari (p< 0,05). Sebagai kesimpulan, lamaperendaman dan jenis larutan (cuka apel) dapat menyebabkan perubahan dimensi pada resin akrilik heat cured.

Abstract

Background: Teledentistry is considered capable of detecting dental caries remotely without direct contact with patients. Deep learning (DL) algorithms are trained with sufficient datasets to find patterns and models based on learning. By using a DL model, we propose a conceptual framework for the screening of dental caries using smartphones: the DentMA application, a new breakthrough in teledentistry technology. In this study, the DentMA teledentistry application was used for mobile screening for caries. Purpose: This study aimed to analyze the use of DentMA teledentistry to detect dental caries, enamel-dentin caries, and untreated caries, and to determine treatment needs in children. Methods: The participants of this study were 124 children aged 4–6 years. The study was conducted by having the participants' mothers take intraoral clinical photos of the participants using the DentMA teledentistry application on their smartphones. For the photo to be taken, each participant was directed to sit upright, with the head looking straight ahead and the mouth open. Results: The results showed that DentMA teledentistry was capable of detecting dental, enamel-dentin, and untreated caries in children, and its ability to predict dental treatment needs was good (p < 0.005). Teledentistry screening using a mobile phone can detect not only caries but also a relationship between the complaints and the medical histories of patients with dental caries. Conclusion: The DentMA teledentistry application can detect dental caries in children according to the individuals' complaints, including enamel-dentin caries and advanced caries, and can help determine treatment needs.
