Purpose: The purpose of this study was to evaluate the survival and success rates of Korean Osstem implants US II Plus, GS II following loading period. Materials and Methods: Dental records were obtained in total 201 patients who were treated with Korean Osstem implants US II Plus, GS II on both maxillary and mandibular anterior and posterior areas in six different clinics for 2 years from January 2007 to December 2008. Total 430 implants were evaluated clinically and radiographically using predefined success criteria prospectively and following results were obtained. Result: US II Plus, GS II implants showed high survival rates of more than 99% and high success rates more than 90% independent of loading period. As a result of cross analysis to evaluate clinical significance between implant loading period and success rate, the P-value of US II Plus was 0.10 (P>0.05), and the P-value of GS II was 0.17 (P>0.05), which showed no statistical significance. Bone quality, smoking, and edentulous state are factors that can affect the survival and success rates following differently loaded implants, but did not significantly affect in this study. Conclusion: These results suggest that selection of loading period of Korean Osstem implants US II Plus, GS II would be done carefully considering implant install area, the quality alveolar bone, the state of edentulous ridge and experience of operator, though they showed clinically good results on both maxillary and mandibular anterior and posterior areas.

Purpose: This study evaluated trends in tooth extraction due to acute and chronic periodontal disease (PD) using data from the National Health Insurance Service-National Sample Cohort for 2002-2013. Methods: A random sample of 1,025,340 individuals was selected as a representative sample of the population, and a database (DB) of diagnostic and prescription codes was followed up for 12 years. We used multivariate logistic regression analysis to assess the incidence of total extraction (TE), extraction due to periodontal disease (EPD), and immediate extraction due to periodontal disease (IEPD) according to sociodemographic factors (sex, age, household income, health status, and area of residence). Results: The incidence of tooth extraction was found to be increasing, and at a higher rate for TE in PD patients. In 2002, 50.6% of cases of TE were caused by PD, and this increased to 70.8% in 2013, while the number of cases of IEPD increased from 42.8% to 54.9% over the same period. The incidence rates of extraction due to acute and chronic PD increased monotonically. We found that the incidence rates of TE, EPD, and IEPD were all 2-fold higher among patients with high income levels and those who were not beneficiaries of health insurance. Conclusions: The rates of TE, EPD, and IEPD have been steadily increasing despite dental healthcare policies to expand public health insurance coverage, increasing the accessibility of dental clinics. Moreover, the effects of these policies were found to vary with both income and education levels. Consistent patient follow-up is required to observe changes in trends regarding tooth extraction according to changes in dental healthcare policies, and meticulous studies of such changes will ensure optimal policy reviews and revisions.

Objectives: The purpose of this study was to contribute to the provision of a safe practice environment and practical sexual harassment prevention education for dental hygiene students who practice clinically. Methods: A total of 260 students with experience in clinical practice at dental hygiene colleges and universities in Gwangju and Jeonnam was included in this study. From May 1, 2018 to June 30, 2018, subjects were surveyed about sexual harassment experience, sexual harassment related information, self-esteem, and self-assertiveness. Statistical analysis was performed by frequency analysis, independent t-test, Mann-Whitney test, one way ANOVA, Pearson's correlation analysis, and multiple regression analysis. Results: In the sexual harassment survey revealed that 64.3% of offenders were patients and 50.0% of the offenders were in their 40s. A total of 78.6% of the offenders reported harassment in hospital type "dental clinics." Most respondents disclosed that "I did not do anything" (60.7%). Psychologically, 75.0% felt "shame and insult." Self-esteem was high in the fourth grade (3.68). Self-esteem and self-assertiveness were higher among those with no sexual harassment experiences (131.77 and 132.81, respectively; p<0.05). Correlation analysis indicated that self-esteem and self-assertiveness were correlated (r=0.509, p<0.01). Factors influencing the perception of sexual harassment include: three to four months of clinical practice (${\beta}=0.361$), experience of sexual harassment (${\beta}=-0.551$), and self-esteem (${\beta}=0.503$). Conclusions: It is necessary to provide systematic and diverse information to address sexual harassment. A proper perception of what constitute sexual harassment in clinical practice is also relevant. Furthermore, practical sexual harassment prevention education program should be developed and implemented.

The purpose of this study was to serve as a basis for better student practice in dental hygiene and for determining educational direction for dental hygiene clinical education by examining what students and clinical-practice instructors thought on clinical practice and what factors gave an impact to clinical education. For attaining the purpose, an investigation was made of 449 third-grade students in the department of dental hygiene at seven educational institutes in Seoul and Kyoung-gi province. 246 instructors in charge of the clinical practice of the students at dental hospital or clinics were also examined. The findings of this study were as follows: 1. The instructors and students had different opinions on the number of trainees, training time, beginning of training, and assessment(p<0.05). The instructors thought that a trainee was appropriate for an instructor(59.8%), and that training time was not sufficient(30.8%). They considered it proper for students to start practice during the summer vacation of second year(21.5%), and responded that assessment should be done by the dentist, dental hygienist or professor in charge(44.7%). However, the students had an idea that an instructor should take charge of 2 or 3 trainees(47.4%), and that there was a lot of training time(55.7%). They considered it appropriate to start practice in the first term of second grade(l9A%), and thought the assessment should be made by the dentist and dental hygienist in charge(44.8%). 2. The students' satisfaction was clinical practice was affected(p<0.05) by their own selection of training institutes(28.1%), the absence of trainee from other colleges(29.4%), ample practice time(28.3%), implementation of student assessment once a day(45.3%), diverse practice opportunities (45.5%), and easy traffic to the training institute(32.9%). 3. The achivement of clinical practice was influenced by practice opportunities, the degree of faithful treatment performance, the frequency of student assessment, the number of trainees, traffic to training institutes, assistance in understanding theoretical knowledge of clinical practice, and assessment methods(p<0.05).

The aim of this study was to evaluate the clinical relevance of autogenous fresh demineralized tooth (Auto-FDT) prepared at chairside immediately after extraction for socket preservation. Teeth were processed to graft materials in block, chip, or powder types immediately after extraction. Extraction sockets were filled with these materials and dental implants were installed immediately or after a delay. A panoramic radiograph and a conebeam CT were taken. In two cases, tissue samples were taken for histologic examination. Vertical and horizontal maintenance of alveolar sockets showed some variance depending on the Auto-FDT and barrier membrane types used. Radiographs showed good bony healing. Histologic sections showed that it guided good new bone formation and resorption pattern of the Auto-FDT. This case series shows that Auto-FDT prepared at chairside could be a good material for the preservation of extraction sockets. This study will suggest the possibility of recycling autogenous tooth after immediate extraction.

Odontoma is the most common odontogenic benign tumor, and the treatment of choice is generally surgical removal. After excision, bone grafts may be necessary depending on the need for further treatment, or the size and location of the odontoma. Although the osteogenic capacity of a demineralized tooth was verified as early as 1967 by Urist and many other investigators, the cumbersome procedure, including a long demineralization time, may be less than comfortable for clinicians. A modified ultrasonic technology, with periodic negative pressure and temperature control, facilitated rapid and aseptic preparation of demineralized teeth for bone grafts. This approach reduces the demineralization time dramatically (${\leq}80$ minutes), so that the graft material can be prepared chairside on the same day as the extraction. The purpose of this article is to describe two cases of large compound odonotomas used as graft material prepared chairside for enucleation-induced bony defects. These two clinical cases showed favorable wound healing without complications, and good bony support for future dental implants or orthodontic treatment. Finally, this report will suggest the possibility of recycling the benign pathologic hard tissue as an alternative treatment option for conventional bone grafts in clinics.
