Abstract

Introduction: Saliva contains numerous proteins and electrolytes that may serve as biomarkers of pathological conditions, including periodontitis. Saliva flow also influenced by pathological conditions, such as periodontitis. Therefore, saliva analysis, as one of the biomarker source needs to be examined. This study was aimed to analyse the differences salivary inorganic ions levels (calcium, phosphate, and bicarbonate) and salivary flow rate in periodontitis and non-periodontitis patients. Methods: This research was analytic-observational using two groups, the healthy periodontal group consisting of 21 people (PI scores between 0-0.2) and the periodontitis group consisting of 21 people (PI scores between 0.7-8.0). Unstimulated saliva was collected using a passive drolling method. The calcium, phosphate and bicarbonate levels in the saliva were analysed using UV/Vis spectrophotometers. Results: Calcium, phosphate and bicarbonate levels in saliva were different between groups. Salivary flow rate also different between groups. There was a significant difference (p = 0.00) in the calcium, phosphate and bicarbonate levels between groups (t-test), and also significantly different (p = 0.000) salivary flow rate between groups. The higher the salivary flow rate, the higher the levels of calcium, phosphate and bicarbonate would be. Conclusion: Periodontitis condition increases the level of salivary inorganic ions and salivary flow rate because of periodontal inflammation. This inflammation mainly because of plaque deposition and calculus. Increased level of inorganic ions in the saliva such as calcium, phosphate, and bicarbonate, and also the salivary flow rate indicates the existence of a periodontal disease.

Abstract

Background: The success of fixed dentures is influenced by the cementation procedure. Resin cement is the most commonly used luting materials. In addition to resin cement, there are other types of luting materials, preheated resin composite. Preheating resin composite allow the material to have a low level of viscosity, therefore can be used as luting material. The purpose of this study was to evaluate the comparison of the shear strength cementation of preheated resin composite and resin cement on indirect lithium disilicate.Method: This study is experimental laboratory with post test only control group design. The sample in this study are 12 pieces lithium disilicate with diameter 5.5 mm x 3 mm cemented divided into three groups based on types of luting materials (preheated resin composite microhybrid, preheated nanohybrid, and resin cement). After the cementation procedure, the samples were immersed in artificial saliva at 37ÂșC for 24 hours. The shear strength test was carried out with a universal testing machine. Data analysis with using One Way ANOVA.Result: The results of the average shear strength of each group were 11.98 MPa for preheated microhybrid, 11.41 MPa for preheated nanohybrid, and 14.22 MPa for resin cement. The results of the One Way ANOVA test showed that there was a significant differences between groups (p value 0.000).Conclusion: There was a significant difference in shear strength between preheated microhybrid, preheated nanohybrid, and resin cement. The highest shear strength was the resin cement group.
