Abstract

Pengunaan produk-produk alam di bidang kedokteran saat ini semakin berkembang pesat. Salah satu bahan alami yangdigunakan adalah kitosan. Tujuan penulisan ini adalah untuk menjelaskan kegunaan kitosan di bidang kedokteran gigi.Kitosan (poly-β-1,4-glukosamine) merupakan makalah biopolymer alami di alam yang memiliki rantai linear denganrumus struktur (C6H11NO4)n yang dapat diperoleh dari proses destilasi kitin. Kitin ditemukan banyak pada hewan lautberkulit keras seperti blankas, kepiting, kerang, udang, rajungan, cumi-cumi, jenis serangga dan jamur. Kitosan memilikibeberapa sifat yang menguntungkan seperti biokompatibel, biodegradable, tidak beracun serta mucoadhesion sehinggakitosan sering digunakan pada pengaplikasian biomedis. Sebagai kesimpulan, kitosan dapat digunakan sebagai antibakteri, menghambat/ membunuh mikroorganisme, menurunkan rasa nyeri, serta memperbaiki sifat-sifat material dibidang kedokteran gigi.

Abstract

Background: The addition of other ingredients to maintain color stability of heat polymerized polymethylmethacrylate is being developed. One of them is by adding high molecular nano chitosan. Purpose: This study aimed to determine the color stability of heat polymerized polymethyl methacrylate denture base resin after an addition of high molecular nano chitosan. Method: 30 sample pieces of acrylic plate (40x10x2 mm) were divied into 6 groups: control group and groups with the addition of chitosan nano gel percentages of 0.25, 0.50, 0.75, 1.0 and 1.50%. 2 ml chitosan nano gel was added into the mixture of acrylic resin with 23 g : 10 ml (P : L). After the mixture was inserted into a mold and then pressed and cured at 74oC for 120 minutes and then 100o C for 60 minutes. Acrylic plates were then released from the mold and finished. Color stability of acrylic resin were measured using UV-Vis Spectrophotometer and analyzed with a one way Anova. Result: The results showed significant differences in color stability after the addition of high molecular nano chitosan. The best color stability found in 1.0% the addition of chitosan nano gel group, the value was 0.07589 cm-1. Conclusion: The chitosan nano gel can be used to maintain color stability of heat polymerized polymethyl methacrylate denture base resin.

Abstract

Background: The main problem in dental and oral health among children is dental caries, a complex disease that begins with acid production that destroys dental minerals. When the pH drops to below 5,5, demineralization occurs faster than remineralization, potentially causing cavities. One approach to addressing this issue is by increasing salivary pH. Purpose: This study aims to determine the effect of gargling with propolis mouthwash on increasing salivary pH among children aged 7-9 years. Methods: This laboratory experimental study used a pretest-posttest controlled-group design. A total of 40 respondents from PAB 12 Sampali Elementary School were selected through purposive sampling. Salivary samples (5 ml) were collected and pH levels measured using a pH meter. Results: The Wilcoxon test showed that the average salivary pH before using propolis mouthwash was 6.39, increasing to 7.07 after use. There was a significant effect of propolis mouthwash on salivary pH (p-value = 0.000). Conclusion: The findings indicate that propolis mouthwash effectively increases salivary pH in children aged 7–9 years.
