Abstract

Streptococcus mutans plays an important role in the pathogenesis of caries. This bacteria has virulence properties involve in the formation of biofilm on tooth surface. Due to its antibacterial effect, Jamblang leaf may be used as an agent to prevent caries. Objective: This study aimed to elucidate the effects of ethanolic extract of Jamblang leaves on the growth of S. mutans. Methods: Analysis of active compounds was carried out using thin layer chromatography (TLC) and Liquid Chromatograph-Mass Spectrography (LC-MS). Samples of S. mutans were isolated from children’s carious deciduous molar teeth. Growth test was done by dilusion technique. Aquadest was used as a negative control. Results: TLC and LC-MS showed the presence of the flavonoid, tannin, and terpenoid Kruskall-Wallis test showed significant differences (p<0.05) among the groups, indicating that Jamblang leaves ethanolic extract decreased the growth of S.mutans. The higher concentrations of the extract, the less number of S.mutans colonies grown. No colony of S. mutans at 22.5% of extract’s concentration. Conclusion: Jamblang leaves ethanolic extract reduces the growth of S. mutans. Concentration of 22.5%Jamblang leaves ethanolic extracthas bacteriocid effect. Key words: Ethanolic extract of Jamblang (Syzygium cumini) leaves, growth, Streptococcus mutans

Abstract

Radiopacity is an important characteristic for restorative materials as dentists have got different abilities in interpreting a lesion or caries in a radiograph. The enforcement of secondary caries diagnosis is a challenge for dentists because they often mistake the diagnosis for restorative materials with low radiopacity. This study aims to determine the differences in the average radiopacity values of certain restorative materials by using conventional and digital radiographs. Moreover, to know the right types of radiographs in distinguishing between radiopacity of certain restorative materials and radiodensity of secondary caries. This is an analytical descriptive study with cross sectional design. The sample was divided into 10 groups of 6, which is dental radiograph filled with glass ionomer cement, resin modified glass ionomer cement, nanofiller and micro hybrid composites as well as teeth with secondary caries which were obtained from conventional and digital radiographs. Next, conventional and digital radiographs were interpreted by observations of 5 dental specialists in which measurement was done by using Image J software to get the average radiopacity values of secondary caries and each restorative material. The results showed that the average radiopacity values for glass ionomer cement are 177.633 ± 6.465 and 187.879 ± 9.305, resin modified glass ionomer cement are179.498 ± 5.597 and 192.078 ± 11.006, composite nanofillers are 194.847 ± 4.952 and 184.401 ± 9.170, microhybridcomposites are 189.109 ± 4.251 and 179.585 ± 6.809, finally secondary caries are 161.772 ± 9.256 and 109.988 ± 7.684 for conventional and digital radiographs respectively. Then the data was analyzed by using T test with significance value of p <0.05. As a conclusion, this study shows no significant difference in the radiopacity of four restorative materials if compared between conventional and digital radiographs while digital radiograph shows significant difference between radiopacity values of restorative materials and secondary caries. Whereas, conventional radiograph does not show significant difference between restorative materials and secondary caries.

Abstract

Recurrent aphtous stomatitisis a recurrent oral ulcer. Clinically recurrent aphtous stomatitis is easy to diagnose, but its etiology and pathogenesis remain unclear because it has no single or specific cause. The main predisposing factors associated with recurrent aphtous stomatitis are genetic factors, hematological and immunologic abnormalities, local factors such as trauma, and smoking cessation. Several studies have shown that hematological abnormalities can affect the oral mucosa and cause recurrent aphtous stomatitis. The purpose of this study was to examine the relationship between recurrent aphthous stomatitis and iron deficiency anemia, as well as the relationship between recurrent aphthous stomatitis and hematological status. The subjects consist of 59 recurrent aphtous stomatitis patients and 60 control patients. A full blood examination was carried out for all subjects. Hemoglobin level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and serum iron level are determined for each subject.The result of this study showed that there is no significant difference in hemoglobin level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and serum iron level with p-value of 0.714, 0.395, 0.809, 0.497, and 0.368, respectively. The result also showed that there is no significant difference in iron deficiency anemia status between the recurrent aphtous stomatitis and control group (p = 0,7). Therefore, it can be concluded that there is no relationship between iron deficiency anemia and recurrent aphtous stomatitis incidence.
