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.

The purpose of this study is to discuss the economic outlook of dentistry in relation to pessimistic economic perspectives of Korea and to present subsequent solutions. The expectation of the future economic growth rate of Korea is gloom with not only a love rate of increase in population due to an aging society and a low birthrate, but also with a declined number of productive populations. Moreover, the future of dentistry in Korea is obscure. Even with a dwindling population growth, an average of 750 new dentists graduate from dental school every year. The 30-35% of the new graduates practice in public hospitals; and 65~70% of them open up their own private practices, However, unlike in the past, the occurrence of dental practice bankruptcy has been increasing with a competitive environment, excessive initial investment, knowledgeable patients, and etc. Therefore, it is essential to re-evaluate the number of new graduates. Also, it is necessary to supply a greater number of public hospitals with newly licensed dentists, who have various clinic experience, participate in research and development, and experience appropriate hospital management skills.

Objectives: Surgical intervention for removal of an impacted third molar can lead to significant pain and swelling. Corticosteroids show promise for mitigating postoperative sequelae across various surgical contexts. The use of corticosteroids following minor oral surgery, though controversial, has already been proven effective. However, little research has explored peroral prescription of corticosteroids despite its convenience for outpatients and for non-surgeons like implantologists and periodontists and others who don't have access to needle injections. The aim of this study was to address a void in the literature by comparing the effects of two styles of preoral administration of prednisolone after surgical removal of the mandibular third molar and to determine which style minimizes postoperative sequelae. Materials and Methods: A randomized, split-mouth clinical study was conducted to investigate the efficacy of two different styles of preoral prednisolone in mitigating postoperative sequelae following surgical extraction of impacted mandibular third molars. Fifteen participants were enrolled in the study. Random selection was used to determine the prescription style for the right and left mandibular arch. Group A included those who received a single dose of prednisolone 25 mg, while group B received prednisolone 5 mg postoperatively for a period of three days (5 mg three times/day on the first postoperative day, 5 mg twice/day on the second postoperative day; 5 mg once/day on the third postoperative day). Results: There was a significant difference in the distance between the corner of the mouth and tragus, which decreased with the time interval with respect to group B when compared to group A. Conclusion: The present study showed that a three-day tapered dose of prednisolone postoperatively was more effective in reducing post-extraction sequelae than a single-dose regimen.

Various techniques are well documented to obtain anatomic reduction, such as reduction forceps, manual reduction, or a combination of these methods. However, these techniques have inherent drawbacks. We propose a new intra-operative technique for anatomic reduction using screw-wire traction for open reduction and internal fixation of mandibular fractures.

The requirements for the successful treatment of all-ceramic restorations are not so different from the ones of conventional restorations. "The provisional restoration followed by an adequate tooth reduction" and "the accurately fitting prostheses with corresponding to final impression" can be the examples of them. Nevertheless, the one which all-ceramic restorations are distinguished from conventional restorations is the additional procedure of so called "bonding". In addition to the application of resin cement between "inner surface of restoration and outer surface of abutment", bonding technology can be also applied to the treatment process of "Post and Core" in particular if the abutments are non-vital teeth. Core build-up for all-ceramic crown is conducted with fiber post and tooth colored composite by considering the properties of the restorations transmitting light. I would like to share my clinical experience about "silica based ceramic and non silica based ceramic restoration.

Few public health researchers have paid research attention to the location of medical institutions in Korea. Previous studies were published in geography journals, and relied on limited data in terms of geographic regions and the type of medical institutions. This study utilized nationwide data covering 8 types of medical institutions. We obtained data from Health Insurance Review and Assessment Service and National Population and Housing Census. The correlation coefficients of resident, daytime, university-graduate population, and the population of different age groups (fewer than 15, 15~64, 65 or more) were compared to understand their relative association with the location of medical institutions. Medical clinic, dental clinic, oriental medical clinic, and pharmacy, all of which are almost completely operated by private sector, showed strong positive correlation with population. Hospital-level medical institutions, which are operated by both public and private sector, had moderate positive correlation. Daytime population and university-graduate population, rather than resident population, were more correlated with the location of medical clinics. The correlation coefficients of the population of 15~64 age group and the location of medical institutions were greater than that of other age groups. The results showed that daytime and university-graduate population are more important than resident population to explain the location of medicalrelated facilities. The results also suggests that the population of age groups (especially, 15~64) might be one of important influence factors in the location of medical institutions.

Purpose: This study investigated the possible correlation between the mineralization of the second molars and the chronological age of a sample population of the state of Paraiba, Brazil. Materials and Methods: One thousand eight hundred fifty-four digitized panoramic images using a scanner of a private dental radiology service were obtained in six months. Of these, 457 were selected from patients aged 4.6 to 16 years who met certain criteria. The images were assessed twice by a radiologist with 5 years experience. A minimum interval of 30 days between the evaluations of the same patient was established. To analyze the relationship between chronological age, calcification level proposed by Demirjian et al in 1973, gender, and tooth, a multiple linear regression model was adjusted, taking age as the response variable (p<0.05). Results: The gender and calcification level were significantly correlated with the age of the patients (p<0.05). There was a significant difference between the average age of the patients' upper teeth compared to the lower ones in both genders (p<0.05). The dental development occurred earlier in female individuals than in male ones, and there was no significant difference between the right and left second permanent molars. Conclusion: It was observed that ethnic variables are related to certain parameters of age and sex identification in the Brazilian population, providing important information for forensic evaluations.

Emotional state of dental outpatients was studied by means of symptom checklist-90- revision, 229 male and 290 female dental outpatients were subjected at the private local clinic in Pusna, during the period from 1994 to 1995. T-scores from SCL-90-R were analyzed psychologically by means of 90 questionnaires through Korean manual of SCL-90-R. The obntained results were as follows : 1. Mean value of T-scores on 9 basic scales of SCL-90-R in all the dental outpatients was within normal range. 2. T-scores in male were significantly higher than that in female, and there was a significant difference by age group in female. 3. There were higher levels of T-scores in groups of high academic carrier, salaryman, public servant, and unmarried person. 4. T-score of patients with periodontal pain was the highest in all subject groups. 5. While T-score of patients with K01(embedded and impated teeth) was the highest, that of K02(dental caries) was the lowest. 6. T-score in acute group was higher than that in chronic group. 7. T-score of patients treated in field of oral surgery or oral medicine was higher than those of other fields of dental treatments.
