The use of tobacco products, tea, coffee, certain mouthwashes and pigments in the food causes the formation of stain. The research aimed to determine the effect of limestone powder to the cleaning of extrinsic tooth staining (stain). This study used a quasi-experimental design with the design of pre-test - Post-test Design (Campbell and Stanley, 1966, cit. Arikunto, 2006), the research done by using the first observation (pre-test) before the intervention. Furthermore, the post-test after the intervention to determine changes. Variables that influence of limestone powder. The variable affected is extrinsic tooth discoloration (stain). The results showed that smokers after intervention stain brush his teeth with limestone powder showed that the t value of 5.77 with a probability of 0.001. This probability is below 0.05 (significant p <0.05), the null hypothesis is rejected, which means there are differences between the mean scores before the intervention brushing teeth stain with limestone powder on one observation after intervention by brushing your teeth with limestone powder on observation 2 and third, the intervention After brushing teeth with limestone powder stain mean score decreased from 8.50 becomes 7.23 and 6.53.

Background: The accuracy of clinical coding is very important in the proper financing of health care centers. During January to February 2019, only 35 out of 60 obstetrical cases that were well coded (58%) in Naili DBS Hospital and this miscoding would led to a big financial loss. The aim of this study is to determine the effect of training on coding accuracy.Methods: This study was conducted during April 2019 in Naili DBS Hospital using quasi experimental method, with one group pretest and post-test design. All 11 participants were given a pretest consisted of 10 long cases (maximum score=38) and the training was conducted based on the identified needs from the preliminary audit. They were then given a post-test to see the effect of the training.Results: The mean score of pretest was 10.7 and the mean score of post-test was 19.7. The individual scores were normalized and then analyzed using SPSS with paired sample T-test. Based on statistical analysis, p<0.005 meaning the traning is statistically significant on improving the coding accuracy in obstetrical diagnosis.Conclusions: The training has significantly improved the score of well coded obstetrical diagnosis, even though the participants have not reached the maximum score. Furthermore, our study suggests that it is important to analyze the coders’ performance months after the training by conducting a coding audit.
