Abstract

Background: Streptococcus mutans (S. mutans) causes dental caries. S. mutans biofilms are inhibited by the antibacterial properties of Ziziphus mauritiana Lam (Z. mauritiana Lam). Purpose: Evaluating the potential of Z. mauritiana Lam in inhibiting the growth and biofilm formation of S. mutans ATCC 25175 in vitro. Methods: This study used the ethanolic extract of Z. mauritiana Lam as the test material and S. mutans as the research subject. Spectrophotometry (620 nm) was used to assess the growth of S. mutans, the inhibition of S. mutans biofilm using a 1% crystal violet staining was measured by spectrophotometry (520 nm), and the visualization of the biofilm mass was conducted with an electric microscope (200x). Results: At all concentrations, Z. mauritiana Lam displayed excellent growth inhibition of S. mutans 0.04–0.09 (< 300 CFU/mL) and was able to inhibit the formation of S. mutans biofilm with a strong scale of optical density (OD) 0.4 at 24 hours incubation time. At the same time, the incubation time of 48 and 72 hours tended to have moderate-scale biofilm inhibition (OD 0.2–3.9). At a concentration of 25%, the biofilm mass decreased by a relatively small size, the same as the positive control group. At 50%, 12.5%, and 6.25%, it was seen that the S. mutans biofilm mass experienced a dominant loss. Conclusion: Z. mauritiana Lam can be bacteriostatic against the growth of S. mutans and can inhibit the formation of biofilms by degrading the structure and mass of S. mutans biofilms.

Abstract

Background: Candida albicans (C. albicans) was reported as a primary cause of oral candidiasis. Phospholipase enzymes and cell surface hydrophobicity (CSH) are involved in the pathogenesis of its infection. Gracilaria verrucosa (G. verrucosa) is reported to contain flavonoids, tannins, and phenolic compounds, which can inhibit the development of C. albicans. Purpose: The study analyzed the effect of the ethanol extract of G. verrucosa on the inhibition of the phospholipase enzyme and CSH of C. albicans. Methods: The G. verrucosa chemical compounds were examined by phytochemical tests and phospholipase enzyme-inhibiting egg yolk media, and a CSH assay was conducted using xylene. Results: Gracilaria verrucosa contains steroids, terpenoids, tannins/phenolics, and flavonoids. The 25%–100% concentrations inhibit the phospholipase enzyme of C. albicans more strongly at 48 hours than at 12 hours and 24 hours (p < 0.05). Furthermore, the 100% and 75% concentrations substantially affect the inhibition of CSH of C. albicans, with a strong relationship. Conclusion: Gracilaria verrucosa has a more substantial inhibitory effect in suppressing the phospholipase enzyme and CSH of C. albicans.

Abstract

Early Childhood Caries (ECC) is a disease of the hard tissues of the teeth in children under 5 year of age. In addition to the main etiological factors, there are several supporting factors that contribute to the occurrence of ECC, including exclusive breastfeeding, socioeconomic status, dietary patterns and habits of children, and oral hygiene behavior of children. The prevalence rate of ECC in Indonesia is still relatively high, with varying prevalence rates and no recent data on ECC prevalence in Banda Aceh. The purpose of this study is to determine the prevalence of ECC in early childhood and its risk factors. This study is analytical in nature, using a cross-sectional design on children aged 4-6 years who attend the kindergarden in Banda Aceh. A total of 123 children met the inclusion criteria. Data collection was obtained through direct clinical examination of the oral cavity using Debris Index measurements and ECC typing. The results of this study showed that the prevalence of ECC reached 87,1%, and factors such as birth weight, frequency of brushing teeth daily, consumption of milk with a bottle, brushing teeth accompanied by parents, and frequency of consuming sweet foods as snacks were significant factors in the occurrence of ECC.
PERBEDAAN WAKTU PENURUNAN pH PLAK GIGI PADA ANAK KARIES RAMPAN DAN KARIES SEDANG (STUDI PADA SISWA TAMAN KANAK-KANAK FKIP UNSYIAH BANDA ACEH) Syafriza, Dharli; Rahmat, Irwan

Abstract

Bakteri yang terpapar sukrosa akan dengan cepat menghasilkan asam dan menyebabkan penurunan pH plak. Produksi asam oleh bakteri merupakan faktor penting dalam patogenesis karies. Penelitian ini bertujuan untuk mengetahui perbedaan kecepatan menurunkan pH plak mencapai level kritis 5,5 pada anak karies rampan dan karies sedang. Penelitian ini merupakan penelitian analitik dengan rancangan cross-sectional pada 2 kelompok yaitu 25 anak dengan karies rampan dan 25 anak dengan karies sedang berdasarkan pemeriksaan skor deft. pH plak diperiksa dengan alat untuk mendeteksi fermentasi plak kariogenik (plaque indicator kit). Hasil menunjukkan bahwa pH plak anak karies rampan lebih cepat turun mencapai level kritis 5,5 dibandingkan anak karies sedang.Kata Kunci: Plak, pH plak, karies rampan, karies sedang
