Abstract

People in Indonesia often consume food containing sucrose. If the sucrose consumed is in a large amount, it will decrease saliva’s pH and soon teeth destruction will happen. To avoid it, it is necessary to change sucrose consumption habit into another kind of sugar, namely sorbitol. Sorbitol is preferred to use, because it is cheaper and easier to get. Sorbitol is made from cassava, which is plentifully grown in Indonesia. Sorbitol is not good media for bacteria to grow. Because sorbitol has a diol, so it’s difficult to catalyst by glucosyltransferase enzyme, which is produced by bacteria Streptococcus mutans. The conclusion is that sorbitol is difficult to be fermented by Streptococcus mutans so it will not decrease saliva’s pH.

Abstract

Background: Musculoskeletal complaints have been common for dentists since their body is unknowingly often in inappropriate positions when caring for patients. For example, they bend towards patients, suddenly move, and then rotate from one side to another. The repetitive movements are done in long term. High activities and sufficient recovery time can cause a buildup of lactic acid in their blood leading to obstruction of the energy intake from the aerobic system in their muscle cells, resulting in fatigue. As a result, such conditions trigger decreased muscle performances. Purpose: This study aimed to determine the correlation between working positions and lactic acid levels with the risk of musculoskeletal disorders among dentists at Public Health Centers in Surabaya. Method: This research was an analytical observational research using cross sectional approach. Sampling technique used in this research was cluster random sampling with nineteen samples. To evaluate the working positions of those samples, a rapid entire body assessment (REBA) method was used. Meanwhile, to observe the musculoskeletal disorders of those samples, a Nordic body map was used. Data obtained then were analyzed using Pearson correlation test with a significance level (p<0.05). Result: Results of data analysis using the Pearson correlation test showed that the significance value obtained was 0.036. It indicates that there was a correlation between the working positions and the lactic acid levels with the musculoskeletal disorders in those dentists. The results of the Pearson correlation test also revealed that there was a correlation between the working positions and the lactic acid levels among those dentists with a significance value of 0.025. Conclusion: It may be concluded that the wrong body positions during working can increase lactic acid level in the body of dentists. The increased level of lactic acid then can affect their muscles, leading to the high risk of musculoskeletal disorders.

Abstract

Background: Caries constitute an infectious disease that result from the interaction of bacteria with the host and the oral environment. Streptococcus mutans (S. mutans) represents the main bacterium that causes caries. The ability of S. mutans to form biofilms in the oral cavity is influenced by daily nutrient intake. This study of bacterial biofilm proteins can be used in the manufacture of kits for the detection of infectious diseases such as caries in the oral cavity. A biomarker is required for the manufacture of the detection kit. Consequently, research must first be conducted to determine the molecular weight and density of S. mutans biofilm proteins induced by several different daily nutrients, namely; 5% glucose, 5% lactose, soy protein and 5% iron. Purpose: This study aimed to analyse the density of S. mutans biofilm protein induced by 5% glucose, 5% lactose, soy protein, and 5% iron. Methods: The density of the S. mutans biofilm protein bands induced were measured using EZ Imager Gel DocTM software. Results: A band of biofilm protein (61.7 kDa) was obtained from S. mutans induced by 5% glucose, four bands of biofilm protein (180 kDa; 153,9 kDa; 43,9 kDa; 37,5 kDa) from 5% lactose induction and seven bands of biofilm protein (157,9 kDa; 86,6 kDa; 66,5 kDa; 50,1 kDa; 37,9 kDa; 32,3 kDa; 29,4 kDa) from soy protein induction. In contrast, S. mutans induced by 5% iron did not show any protein bands. The proteins that result from each inducer are of differing densities. Conclusion: The protein bands from each inducer are of different densities which can be used in the further test to make a biomarker for dental caries detection kits.
