Abstract

Objectives: A clinical trial was carried out to investigate the inhibitory effect of Achovy of Stelophorus commersonii on the growth of salivary mutans streptococci over one week period. Methods: Before enrolled in the study, respondents filled and signed the informed consent. Twenty respondents participated in the study I, conducting two times of treatment as follows: twenty as treatment group before and after consuing anchovy of commersonii and the twenty subjects as control group before and after consuming non-anchovy of commersonii. Saliva samples were collected before and after consuming anchovy of commersonii and with a non-anchovy of commersonii. A serial dilution was made, followed by inoculating on TYS20B medium (Schaeken, et al, 1986). Data were obtained from colony forming units of salivary mutans streptococci grew on the TSY20B medium before and after consuming anchovy of commersonii were analyzed in a descriptive and t test. Results: showed that there was no significant difference in the average amount of Streptococcus mutans both between before and after consuming non-anchovy of commersonii. However, a significant difference was found respectively as results before and after consuming anchovy of commersonii. Conclusion: Anchovy of commersonii has an antimicrobiala ctivity against local strains of S. mutans isolated from human harbouring species. Long term consumption Anchovy fish of commersonii can be beneficial in preventing caries.DOI: 10.14693/jdi.v16i3.101

Abstract

Secondary caries always occurs as a result of the filling not being hermetically. Purposes of this research is to prove whether there is a leak on the border of the tooth enamel and border between the Glass-ionomer filling with the Streptococcus mutans infection with parameter of SMAAPPI (Simplified S. mutans Approximal Plaque Index by Keeni et al, 1981). The subject of the research were 20 patients who came to the Dental Clinic at University of Indonesia with criteria possessing Glass-ionomer filling at the lower jaws. Collection of the samples were dental plaque gathered using a 1.5 mm excavator to scrape one way direction from the enamel, along the border between the enamel and Glass-ionomer filling and Glass-ionomer fillings surface. Isolation with medium transport sem-synthetic Cariostat and TSY20B and identification by using biochemical test. isolated colony strain local Streptococcus mutans from enamel, the border enamel and Glass-ionomer and the surface of the Glass-ionomer. The results were Streptococcus mutans were found from enamel 3006 colonies, on the border between the enamel and Glass-ionomer 143 colonies and on the surface of the Glss-ionomer 7291 colonies. Amoung of Streptococcus mutans colony obtained on the border of the enamel and Glass-ionomer were smaller compared to the surface of the Glass-ionomer and tooth enamel. Concluded that the leak of the filling was not caused by the number of distributed Streptooccus mutans colonies on the side, because the fluoroapatite fastener occurred due to the Glass-ionomer releasing in fluor along the border of the filling.
