Background:Health-Related Quality of Life (HRQoL) periphrastically has a significant impact on oral health. A recent study has shown the significant facts of the oral health-related quality of life based on many factors such as individual, social status, household management, daily habits, and local factors. The differences in the oral health status possibly occur in between countries, different regions, and topographical areas frequently and indirectly contributing to oral health status.Objective:The objective is to evaluate the difference of Oral Health-Related Quality of Life (OHRQoL) and to assess the main affected dimension between rural and urban areas in Kutai Kartanegara Regency.Methods:This study uses pilot pathfinder design. The respondents comprised of 214 adults who were elder than 18 years and were randomly selected from urban and rural areas in Kutai Kartanegara Regency, Indonesia. The data were collected by 103 samples from the rural area and 111 respondents from the urban area. Oral Health Impacts Profile (OHIP-14) has been translated to Bahasa (Indonesia version). OHIP-14 was used to assess the subjects’ oral health-related impact. Shapiro-Wilk and Mann Whitney tests were used to analyze the data, and p-value was set at P < 0.05.Results:The mean OHIP scores in the urban and the rural areas were 25.4 and 28.8, respectively. The overall OHIP-14 score showed a significant statistical difference P= 0,009 (P < 0.05) between rural and urban area.Conclusion:This study illustrates that oral health-related quality of life in the urban area is better than in the rural area. Physical pain components of the OHRQoL are the major oral problems associated with both the areas.
Objective: The aim of this experiment showed the difference of corrosion resistance between Nickel-Titanium (NiTi) archwire and NiTi archwire with additional cooper (NiTi-Cu) in artificial saliva. Material and Methods: This research was conducted in these laboratory experiments, immersed the NiTi archwires and NiTi-Cu archwires on artificial saliva at pH= 7 and incubated on 37°C, with the ratio of the archwire and the saliva was 0.02 gr: 1 ml during 1 day, 33 days and 66 days.Results: Corrosion resistances reviewed by average saliva artificial contained ion Ni after immersed 1 day of NiTi archwires and NiTi-Cu were 0.033 ± 0.000, and after immersed 33 days were 0.053 ± 0.022 and 0.101 ± 0.050, and after 66 days immersed were 0.101 ± 0.050 and 8.052 ± 3.4667. Conclusion:Based on research conducted, NiTi archwire more resistant to corrosion than NiTi-Cu, ion Ni released shown higher concentration in NiTi-Cu than NiTi.
Latar belakang: Destruksi tulang alveolar secara progresif akan berdampak buruk pada aspek fungsional, estetik, dan prognosis perawatan prostetik. Upaya regenerasi diperlukan untuk mengembalikan fungsi tulang alveolar. Dewasa ini, penggunaan konsentrat platelet seperti platelet-rich fibrin (PRF) dan platelet-rich plasma (PRP) terbukti mampu memicu pembentukan tulang alveolar. Namun, proses penyembuhan tulang memakan waktu lama. Selain itu, volume tulang yang terbentuk sulit dipertahankan sehingga konsentrat platelet perlu dimodifikasi. Penambahan scaffold bone-graft terbukti dapat meningkatkan efektivitas konsentrat platelet. Kandungan silk-fibroin dalam kepompong ulat sutera (Bombyx mori) berpotensi sebagai material scaffold yang ideal karena memiliki sifat mekanis dan biokompatibilitas yang unggul. Tujuan: Mengkaji potensi scaffold silk-fibroin kepompong ulat sutera yang dikombinasikan dengan konsentrat platelet sebagai inovasi terapi regenerasi tulang alveolar. Pembahasan: Mineralized plasmatic matrix (MPM) merupakan terobosan terbaru yang mengkombinasikan scaffold bone-graft dengan PRP dan PRF. Konsentrat platelet dalam MPM kaya akan growth factor (PDGF, TGF-β, VEGF, IGF), monosit, dan serabut fibrin yang berperan dalam menstimulasi proliferasi, diferensiasi, dan migrasi sel-sel osteoprgenitor, dan osteogenik pada area kerusakan. Penggunaan scaffold silk-fibroin yang disintesis dari kepompong ulat sutera mampu meningkatkan efektivitas konsentrat platelet dengan cara mempercepat proses osteogenesis dan menyediakan matriks ekstraseluler yang akan memandu migrasi sel osteogenik saat proses pematangan tulang. Selain itu, silk-fibroin mampu menginduksi angiogenesis, memfasilitasi osteokonduksi, dan mengoptimalkan proses osteoinduksi. Dengan sifat mekanisnya yang unggul, silk-fibroin mampu mempertahankan volume tulang. Simpulan: Perpaduan scaffold silk-fibroin kepompong ulat sutera dengan konsentrat platelet berpotensi dalam menstimulasi dan mempercepat proses pembentukan serta mempertahankan volume tulang alveolar.
