Objectives : This study has made a comparison of the difference between the periodontal parameter before and after applying dental hygiene process on patients requiring supportive periodontal therapy at a private dental clinic. Methods : The entire process was conducted on 74 patients. As a result of analyzing the difference in periodontal parameters such as PPD>4mm, BOP, and O'Leary Index of 29 patients that has completed 1 circle of dental hygiene process. Results : All periodontal parameters in all subject patients had been significantly reduced(p<0.05). Furthermore, as a result of comparing the periodontal conditions of the smoking group and non-smoking group, complier and non-complier, all parameters were reduced with a significant difference in the non-smoking group and the complier, but the smoking group and the non-complier did not show difference in all parameters. As a result of making an assessment of before and after dental hygiene process according to PRA classifications, high risk group has been generally changed to moderate or low risk group. Conclusions : Accordingly, the supportive periodontal therapy applying dental hygiene process has been shown to be effective. The dental hygiene process in periodontal patients who require continuous management is anticipated to be a very efficient process.

This study was to investigate the level of knowledge, recognition, behavior of radiographic safety control and job stress in dental hygienists and to determine the relationship among variables. The subjects were 256(56.9%), who were worked in dental hospital and clinic with mean age of $29.59{\pm}7.30$. Data was collected using a self administrated questionnaire from April 4 to May 15, 2010. Behavior of radiographic safety control was measured using the 15-items and job stress was measured using the 5-items with 5-point likert scale. The data were analyzed with t-test, one-way ANOVA and pearson correlation coefficient using the SPSS WIN 17.0 program. Regarding job stress, the subjects was a mean of 2.63 out of a maximum 5 points. The level of knowledge, recognition, behavior of radiographic safety control a mean of 3.11, 4.08 and 3.43 out of a maximum 5 points. Recognition and behavior of radiographic safety control was negative related job stress in this study. Based on the findings, behavior of radiographic safety control is associated with job stress. These results suggest that various program should be considered for radiation safety control of dental hygienists.
