Abstract

Introduction: Alginate is the most commonly used impression material in dentistry for creating accurate impressions of soft and hard tissues in the oral cavity. Its properties can be modified by adding starch, as both alginate and starch contain polysaccharides. This modification affects not only alginate's dimensional stability but also its setting time. This study aimed to analyze cassava starch and modifies cassava starch on the setting time of alginate. Method: This experimental laboratory study measured the setting time of pure alginate, alginate with 40% cassava starch, and alginate with 40% modified cassava. Analyze data using Anova and Post Hoc LSD Test. Results: The fastest setting time was observed in pure alginate (89±2,23 seconds), followed by alginate with 40% modified cassava starch (150±3,01 seconds), and alginate with 40% cassava starch exhibited the longest setting time (211±3,57 seconds). A one-way ANOVA test showed significant differences between the setting times of pure alginate, alginate with 40% cassava starch, and alginate with 40% modified cassava starch. The post hoc LSD test showed that there were significant differences in each treatment group. Conclusion: The addition of cassava starch and modified cassava starch affects the setting time of alginate. Pure alginate sets the fastest, followed by alginate with modified cassava starch, while alginate with cassava starch has the longest setting time. The addition of both natural and modified starch has a significant effect on the setting time of alginate with different effects between the two.

Abstract

Introduction: Lactobacillus acidophilus is one of the dominant bacteria that plays a significant role in the development of dental caries. This bacterium produces extracellular polysaccharides that facilitate bacterial adhesion to dental plaque. One of the approaches to preventing dental caries is the use of antibacterial agents to inhibit bacterial growth in dental plaque. Averrhoa bilimbi (cucumber tree fruit) leaves have the potential to act as antibacterial agents due to the presence of active compounds that can inhibit bacterial growth. Aim: To determine the effect of Averrhoa bilimbi (cucumber tree fruit) leaf extract on inhibiting the growth of Lactobacillus acidophilus ATCC 4356. Methods: This study was an experimental laboratory with a post-test only control group design. The concentrations of Averrhoa bilimbi leaf extract used were 6.25%, 12.5%, 25%, and 50%, and a negative control of aquadest (sterile water). Results: The analysis with One Way ANNOVA showed p-value < 0.05, indicating a significant effect of Averrhoa bilimbi leaf extract in inhibiting the growth of Lactobacillus acidophilus ATCC 4356. Conclusion: Averrhoa bilimbi (cucumber tree fruit) leaf extract has an effect on inhibiting the growth of Lactobacillus acidophilus ATCC 4356. These findings suggest the potential of Averrhoa bilimbi leaf extract as a natural antibacterial agent

Abstract

Masih tingginya prevalensi karies gigi pada anak usia sekolah dasar (SD) di Sumatera Barat (50,19%) dan Kota Padang (36,7%) salah satunya disebabkan oleh perilaku oral higiene anak yang tidak adekuat, sehingga penting dilaksanakan “brush up campaign” sebagai program promotif, edukatif secara holistik dan komprehensif. Tujuan kegiatan pengabdian kepada masyarakat ini adalah untuk meningkatkan pengetahuan anak usia SD dalam menjaga kesehatan gigi dan mulut, serta mampu mempraktikkan cara menyikat gigi yang benar. Perubahan tingkat pengetahuan siswa diukur menggunakan kuesioner berisi pertanyaan mengenai waktu, durasi, frekuensi, teknik menyikat gigi dan pemilihan sikat gigi yang telah diuji validitas dan realibilitasnya. Tahapan kegiatan dimulai dengan persiapan, pelaksanaan, pendampingan, evaluasi dan keberlanjutan program. Kegiatan pengabdian ini diikuti oleh 300 siswa dari SDN 35 Padang Sarai dan SDIT Bakti 2 Nairatul Jannah, di wilayah kerja Puskesmas Anak Air, Padang, Sumatera Barat. Siswa diminta mengisi kuesioner sebelum dan setelah edukasi secara interaktif, dilanjutkan dengan praktik sikat gigi bersama di halaman sekolah. Data dianalisis dengan sistem komputerisasi. Hasil setelah edukasi menunjukkan persentase peningkatan pengetahuan siswa mengenai waktu (100%), durasi (92,67%), frekuensi (99,67%), teknik menyikat gigi (99%) dan pemilihan sikat gigi (99,33%). Efektivitas kegiatan brush up campaign ini didukung dengan meningkatnya pengetahuan dan seluruh siswa mampu mempraktikkan teknik menyikat gigi yang benar.
