"Streptococcus mutans serotype E is a major bacterium causing caries, and widely present in dental plaque. Dentifrices containing xylitol have been shown to inhibit the growth of these mutans streptococci. The aim of the study was to identify the influence of dentifrice containing xylitol on S. mutans serotype E (in vitro). The 1:1 solution of dentifrice containing xylitol was diluted to the test concentrations of 100%, 10%, 1%, 0.1%, 0.01%, and 0.001%, in addition to positive and negative control groups. These solutions were examined in S. mutans serotype E test cultures by the diffusion method. The resulting inhibition zone was 2.16 mm at a concentration of 10%, and 3.0 mm at a concentration of100%. Zero zone size was found at all other test concentrations,and a significant (Spearman) negative correlation was indicatedbetween the concentration of dentifrice and the growth of mutansstreptococci (p<0.05). The MIC was not been identified, but MBC was 10%. In conclusion, the dentifrice containing xylitol can significantly inhibit the growth of S. mutans serotype E at least at dentrifice concentrations of 5-10%."

"Streptococcus mutans serotype C is a major causative agent to caries and is found predominantly in dental plaque and saliva. Dentifrice containing xylitol has been shown to inhibit the growth of mutans streptococci. The aim of the study was to identify in vitro the influence of dentifrice containing xylitol on S. mutans serotype C. The solution of dentifrice containing xylitol was first diluted with sterile aquadest at 1:1, and then to concentrations of 100%, 10%, 1%, 0.1%, 0.01%, and 0.001%, also with positive and negative controls. These solutions were exposed to S. mutans Serotype C by diffusion and dilution method. The results of the study show that the inhibition zone formed at concentration of 10% and 100%. There was a significant positive correlation between the concentration of dentifrice and the growth of mutans streptococci (p<0.05), with MBC point at 10%. In conclusion, dentifrice containing xylitol has an antibacterial effect and can inhibit the growth of S. mutans serotype C. Increasing concentration of dentifrice containing xylitol increases the size of the inhibition zone."

Tujuan Penelitian: Menganalisis pengaruh paparan pasta gigi ekstrak propolis dan pasta gigi non-propolis terhadap pertumbuhan biofilm S. mutans ATCC 25175. Metode Penelitian: Pembentukan biofilm dilakukan dengan kultur S. mutans ATCC 25175 ke dalam well yang telah berisi pelikel. Pasta gigi ekstrak propolis dan non-propolis dimasukkan ke dalam well, serta diinkubasi selama 3 jam dan 18 jam. Uji kristal violet dan uji OpenCFU dilakukan untuk mengevaluasi total biomassa. Hasil Penelitian: Pada inkubasi 3 jam, tidak terlihat adanya penurunan biomassa baik pada pasta gigi ekstrak propolis maupun non-propolis.

Background: Toothpaste was a semi-aqueous material that is used to maintain dental and oral hygiene. Commonly, the active ingredients contained in toothpastes were made from synthetic ingredients. However, these ingredients may causes several adverse effect, therefore a biocompatible ingredient is required to minimize the adverse effect. Propolis is a resin substance that has antibacterial properties and non-toxic to the body. Thus, propolis can be used as an active substance in toothpaste to minimize the adverse effects caused by synthetic toothpaste.

Aim: To analyze the effect of propolis extract and nonpropolis toothpaste exposure toward S. mutans biofilm ATCC 25175 growth.

Method: S. mutans ATCC 25175 culture was added to the well that already contained pellicle to make biofilm. Both toothpaste was added into the well and incubated for 3 h and 18 h. Crystal violet and OpenCFU method was used to measure total biomass of S. mutans ATCC 25175 biofilm.

"Masalah: Pemakaian gigi tiruan sebagian lepasan sangat erat hubungannya dengan terjadinya akumulasi plak dan depositnya, yang menjadi tempat menguntungkan untuk pertumbuhan bakteri. Pada gigi tiruan sebagian, penumpukan plak paling banyak terdapat di daerah servikal yang berhadapan dengan gigi penyangga, sehingga bakteri dapat pula berkoloni pada gigi penyangga dan menyebabkan karies gigi.Oleh karena itu sangat diperlukan pembersihan gigi tiruan yang dapat mengurangi pertumbuhan bakteri khususnya bakteri Streptococcus mutans yang berhubungan dengan etiologi karies. Telah terbukti bahwa pembersihan gigi tiruan secara kimiawi yaitu dengan cara perendaman dalam larutan pembersih seperti alkalin peroksida, sodium bikarbonat dan sodium hipoklorid 0,5% lebih efektif menjangkau seluruh permukaan basis gigi tiruan dibandinngkan pembersihan secara mekanik Tujuan: Untuk mengetahui lama perendaman larutan pembersih gigi tiruan yaitu alkallin peroksida, sodium bikarbonat dam sodium hipoklorid 0,5% yang dapat mengurangi jumlah koloni S.mutans pada basis resin akrilik permukaan halus dan kasar.

Background:The usage of partial removable denture is strongly associated with accumulation of plaque and its deposits, which is an ideal place for bacterial growth. Plaque deposits in partial removable denture commonly found in cervical area adjacent to abutment tooth and caused bacterial colonization on abutment tooth which led to the occurrence of dental caries. That is why application of denture cleaning solution that will reduce bacterial growth, especially Streptococcus mutans which related to caries formation etiology, is crucial. It has been proven that chemical cleansing of denture by soaking the removable denture in chemical cleaning solution such as sodium hypochlorite 0,5% and sodium bicarbonate is more effective the area inaccessible by mechanical cleansing. Objective:To determine the effect of rinsing duration of cleaning solution, such as sodium bicarbonate and sodium hypochlorite 0,5%, to S.mutans bacterial colonies on smooth-surfaced and rough-surfaced acrylic resin plate. Method:This laboratory experiment was conducted using 48 specimens, with 24 smooth-surfaced and 24 rough-surfaced acrylic resin plates. After S.mutans contamination, the specimens were rinsed in 3 different cleaning solution and aquadest which served as control, for the duration of 5 and 10 minutes. Afterwards, the specimens were cultured in blood agar mediums and kept inside incubator for a period of time, and then colonies of S. mutans formed in the medium were counted. Results:Statistical analysis showed that the rinsing of acrylic plate in sodium hypochlorite 0,5% for 5 and 10 minutes significantly reduced S.mutans colonies compared to rinsing in alkaline peroxide and sodium bicarbonate for both the smooth and rough-surfaced specimens. Conclusion:Soaking of acrylic plate in sodium hypochlorite 0,5% for 5 and 10 minutes is the most effective way to reduce S.mutans colonies in both the smooth and rough-surfaced specimens."
