Abstract

Background: The decrease and increase of bulk-fill composite resin storage temperature are infunction to extend the expiration period and obtain lower viscosity, making it easier for application of composite resin. Temperature is one that affects the polymerization process. Different polymerization qualities will affect the physical and mechanical properties of the composite resin, one of which is the diametral tensile strength. Purpose: To analyze the difference of tensile strength value of diametral bulk-fill composite resin stored at low temperature (5˚C), room temperature (25˚C) and high temperature (35˚C). Method: 33 specimens with 6 mm diameterand 3 mm thicknesswere divided into three treatment groups consisted oflow temperature storage group (5˚C), room temperature group (25˚C)and high temperature group (35˚C). The diametral tensile strength wasmeasured by Universal Testing Machine and analyzed by One Way Anova and Post Bonfond Bonferroni test. Result: The mean diametral tensile strength of bulk-fill composite resin with storage temperature 5˚C (35,85 MPa), 25˚C (42,72 MPa) and 35˚C (45,73 MPa). One Way Anova Test obtained p value = 0,001 (p>0,05) and continued with Post Hoc Bonferroni, so it can be concludedthat there was significant difference in the value of diametral tensile strength of bulk-fill composite resin with 25˚C and 35˚C storage temperature compared with 5˚C, and there was no significant difference in diametraltensile strengthof bulk-fill composite resin by comparing the temperature treatment of 25˚C with 35˚C. Conclusion: The diametral tensile strength value of the bulk-fill composite resin are increased as the storage temperature increase.

Abstract

Background: Asthma is chronic airway inflammatory disorder where mast cells, eosinophils, and T lymphocytes play important role.The symptoms include wheezing, recurrent cough, shortness of breath, and suppressed chest. The age prevalence of asthma children is quite high and increases annually. Asthma affects boys twice the rate of the asthma as girl. Asthmatic patients need local immunity and antibodies so infections that occur in the oral cavity as a result of inhalation medication use can be avoided. The antibody of the oral defense system is secretory immunoglobulin A (sIgA). Objective: To explain the difference in salivary sIgA levels in male asthmatic children and female asthmatic children.Methods: The study was conducted on 21 subjects of asthmatic children consisted of 11 male and 10 female with the age range 9-11 years. Saliva sampling was taken in RSKP Respira Bantul, then it was taken to Laboratory of Molecular Biology FK UGM for ELISA test. Saliva was taken by Spitting method for 1.5 mL and done in the morning from 8-11 hours. Subjects were not allowed to eat 1 hour prior to salivary taking. Anamnesis and clinical examinationwere performed to see the condition of oral cavity, social status, and nutritional status. Saliva measurementusing Anti-human sIgA ELISA kit (Elebscience). Data were analyzed using Independent T test. Results:The mean of sIgA level in males was 0.18 × 10 ± 0.06 and females was 0.15 × 10 ± 0.03. Based on the results of the Independent T test, it was found that the p value =0.283 (p> 0.05). Conclusion: There is no difference in sIgA levels between male and female patients.
