Abstract

Background: Glass ionomer cement (GIC) is a restoration material that has the ability to release Fluoride ion. The Extrinsic factor that affect the solubility of fluoride is low or acidic pH. Streptococcus sp and Lactobacillus sp are asiduric and acidogenic bacteria which are resistant to acidic conditions and may produce acid. A lower pH (acid) causes higher level of fluoride to be released. Objective: This study was to analyze the effect of Streptococcus sp and Lactobacillus sp attachment on solubility of fluoride level on GIC restoration Method: Twenty-one specimens (5mm diameter x 2mm thickness; n = 7 / group) were fabricated with GIC. The treatment group (Streptococcus sp and Lactobacillus sp) while the control group (Artificial Saliva) was immersion for 7 days in an incubator 37oC. Solubility of fluoride was measured using a pH meter Lutron (208) TL Lutron (Taiwan). Result: One Way Anova and Post Hoc Bonferonni showed that there were significant differences between the treatment groups of Streptococcus sp (5.13 ± 0.86ppm) and Lactobacillus sp (6, 02 ± 0.79ppm) with artificial Saliva group controls (3.03±0,56ppm). Conclusion: There was an effect of Streptococcus sp and Lactobacillus sp bacteria attachment on the solubility of fluoride from the GIC restoration.

Abstract

Backgrounds: Bulk-fill composite resin is a new type of composite resin that has the ability to absorb polymerization rays up to a depth of 4-5 mm in a single cure because of the modification in its components formation. The main cause of composite resin restorations failure is discoloration. Discoloration may occur due to extrinsic factors such as consuming food or drink which is rich in color and low pH, namely probiotic milk. Consuming probiotic milk for a long time will significantly increase the risk of composite resin discoloration. This significant discoloration eventually causes shorter resistance of restoration in oral environment regarding the decrease in aesthetic value. Objectives: To determine the effect of probiotic milk immersion on bulk-fill composite resin discoloration. Methods: This research was true experimental study with pretest-posttest with control group design that consisted of six groups in total of thirty six samples. Discoloration will be analyzed using digital analysis with the CIELAB method. Results: One-way ANOVA and Post-Hoc Games-Howell tests showed significant differences on bulk-fill composite resin discoloration after immersion in probiotic milk and distilled water (control) for 6, 12 and 18 hours (p<0,05). Only in the immersion groups of 6 hours and 12 hours probiotic milk did not have a significant difference on discoloration (p>0,05). Conclusion: There is an effect of probiotic milk immersion on bulk-fill composite resin discoloration.

Abstract

ABSTRACTBackground:Resin-based sealers are widely used because they have good physical and biological properties and form micro-retention in dentin. There are also non-resin-based sealers. A non-resin-based sealer also has good micro-retention properties. The bond between dentin and the sealer can be improved by removing the smear layer. 2.5% NaOCl and 17% EDTA are the most common combination of irrigation solutions used to remove the smear layer. The use of 2% chlorhexidine after 17% EDTA at the end of irrigation will increase the antimicrobial effect and inhibit the activity of matrix metallo-proteinase (MMP).Objective: to determine push-out bond strength of obturation material with resin and non-resin sealers with 2.5% NaOCl, 17% EDTA and 2% CHX irrigation solution.Methods: The study used a true experimental method (post-test only group design). The treat­ment group (obturation with gutta percha and resin sealer; gutta-percha and non-resin sealer; gutta-percha only) were tested using a univer­sal testing machine. Statistical tests using the Kruskal Wallis test and Mann Whitneytest.Results:Kruskall Wallis test showed that there were differences value of push-out bond strength in different obturation material with gutta percha and resin sealer; gutta-percha and non-resin sealer; gutta-percha only (p <0.05). The Mann Whiney test showed a significant difference bond strength between the non-resin sealer obturation group and gutta percha only group and between between the resin sealer obturation group and gutta percha only group (p<0.05).Conclusion:The use of sealer (a resin-based sealer and non-resin-based sealer) and 2.5% NaOCl, 17% EDTA and 2% CHX as irrigation solution can increase the bond strength of the obturation material. Keywords:bond strength, non-resin based sealer, resin based sealer. ABSTRAKLatarbelakang:Sealerberbahandasar resin banyakdigunakankarenadapatmembentukretensimikro pada dentin.
