Abstract

Smear layer removal in root canal treatment is required to aid the diffusion of intracanal medicament and help sealer penetrate into dentinal tubules. The need for irrigants is important to facilitate smear layer removal in the root canal. Various methods have been proposed in some articles, but their application in apical third still challenges many clinicians due to the complexity of the root canal. This study aimed to analyze the effect of temperature and passive ultrasonic irrigation (PUI) activation of EDTA 17% solution in smear layer removal. Twenty-four extracted mandibular premolars were decoronated to standard root length of 14 mm. The preparation of root canals was completed with crown-down technique using ProTaper FHU to file F3 (30/.09). The root canal irrigation was done with NaOCl 5.25% and EDTA 17% solution. The samples were divided into four groups, namely 25 ºC of EDTA 17% solution (group 1), 37 ºC of EDTA 17% solution (group 2), 25 ºC of EDTA 17% solution with PUI activation (group 3), and 37 ºC of EDTA17% solution with PUI activation (group 4). Smear layer removal was observed under scanning electron microscopy (SEM) and scored ordinally from 1-5. Non-parametric Friedman test showed significant results in all the groups (p<0.05). Post hoc Wilcoxon Signed Rank test showed significant results between group 2 and group 3 (p = 0.039), and between group 3 and group 4 (p = 0.038). The combination methods of temperature and PUI activation showed a significant result in smear layer removal.

Abstract

Introduction: Oral and maxillofacial tissue status has a significant impact on the systemic health of elderly patients. Elderly patients without oral diseases are rare to find by dentists. Literature Review: Prevention and treatment for caries and periodontal diseases should be done for elderly patients, except in particular conditions when its not worth the risks treatments. Although the relationship between oral diseases and systemic diseases is still controversial and unresolved, it can be assumed that elderly patients have a greater risk of acute and chronic oral infections due to the use of various drugs and medical disorders, impaired immune function, age related impaired kidney, liver and cardiovascular dysfunction. Conclusion: While on duty, dentists who provides care to elderly patients, must know the medical history and systemic review, and understands general medical problems that affects oral care of the elderly.Keyword : medical problem, elderly, oral treatment

Abstract

Background: Composite resin often used as a restoration material due to its advantages in the aesthetic field. The bulk-fill type is one of the composite resin that can be applied directly into cavities as deep as 4 mm, so that restoration procedure becomes easy and effective. Hence, exposure to various acidic drinks can reduce the hardness of composite resins and eventually lead to failure of the tooth restoration process.Objective: This research aimed to evaluate the effects of several commercial acidic drinks, (carbonated, isotonic, and yogurt) on the hardness of bulk-fill composite resins.Method: This research was an experimental study with a post-test control group design. Twenty-four specimens were made with the size 10 x 4 mm using the metal mold rings. Specimens were divided into 4 groups for artificial saliva (served as a control), carbonated, isotonic, and yogurt. Specimens were immersed in storage agents for 5 seconds followed by artificial saliva for 5 seconds. This cycle was repeated 20 times for 14 days. The bulk-fill composite resin hardness was measured using a Micro Vickers Hardness Tester with a load of 100 grams for 10 seconds. Statistical analysis was performed using One Way ANOVA and Post Hoc LSDResults: Data were normally distributed and homogeneous with p > 0.05. The One Way ANOVA test showed the biggest difference in bulk fill composite resin between 4 groups (p < 0.001). The Post Hoc LSD test showed significant differences between all groups (p < 0.001)Conclusion: Carbonated, isotonic, and yogurt drink significantly decreased surface microhardness of bulk-fill composites resin but the carbonated drinks greatly reduce the hardness value since it has the lowest pH of 2.3.

Abstract

Objectives: To determine the effect of lemongrass infusion on the growth of Streptococcus mutans at various concentrations. Methods: This study used post test only control group design with total sample is 9 samples, concentration 100%, 50%, 25%, 12,5%, 6,25%, 3,125%, 1,56%, positive control, and negative control with 3 replications. The research uses dilution method by looking at the turbidity which can be marked as MIC, for MBC used pour plate method was determined by looking at the presence or absence of bacterial growth on the plate. Data analysis was performed using the spss application using Kruskal-Wallis test with significance level if the result of p<0,05. Results of Study: The results of the sample group were 100%, 50%, 25%, 12,5%, 6,25%, 3,125%, 1,56% in the MIC test showed turbidity in all samples, then the MBC test showed growth bacteria in all samples. The assessment of the probability test p value of 1,000 (>0,05) indicates that there is no significant difference between research groups. Conclusion: There was no effect of lemongrass stem infusion with various concentrations on the growth of Streptococcus mutans.
