Introduction: Bone resorption is a unique function of osteoclasts. Osteoclasts are a specialized macrophage polykaryon whose differentiation is regulated principally by macrophage colony-stimulating factors, receptor activator of nuclear factor ${\kappa}B$ ligand (RANK) ligand, osteoprotegerin (OPG), and interleukins (IL). Reflecting the integrin-mediated signals, osteoclasts develop a specialized cytoskeleton that allows it to establish an isolated micro-environment between itself and the bone, wherein matrix degradation occurs by a process involving proton transport. The levels of IL-1, IL-6, OPG, and prostaglandin $E_2$ ($PGE_2$) expression were evaluated to study the correlations between dental implant teeth and the adjacent teeth. Materials and Methods: The exudate of the gingival crevice acquired from dental implants, adjacent teeth, opposite teeth and contralateral teeth of 24 patients. Results: 1. The levels of IL-1, IL-6, OPG and $PGE_2$ expression in dental implant teeth were higher than those of the contralateral teeth. 2. IL-1 revealed a higher expression level in the adjacent teeth than in dental implant teeth. 3. The dental implant teeth and adjacent teeth did not show a remarkable difference in the level of IL-1 expression. 4. All the other cytokines were strongly expressed in the dental implant compared to the adjacent teeth. Conclusion: These results suggest that there might be close correlation between dental implant teeth and adjacent teeth in terms of the expressions of cytokines that affect the development and regulation of osteoclasts.

Methods:A total of 270 surveys were analyzed in this study. The survey consists of 5 questions on general issues; 10 on the awareness of present work of dental hygienist; and 1 on opposition or approval about including dental hygienist in medical personnel. The collected data were analyzed using SPSS for Windows 18.0, as well as frequency analysis, cross analysis and logistic regression analysis. Statistical significance level (${\alpha}$) is 0.05. Results: 1. Broken down by gender, male subjects showed more oppositions against including dental hygienists in the category of medical personnel while female subjects showed more favorable opinions (p<0.05). In terms of academic background, those who had graduated from graduate school or higher showed a higher propensity for opposition while those who had graduated from a 3-year college showed a higher tendency for approval on the idea (p<0.05), In terms of occupational type, health professionals showed more opposing views whereas medical technologists showed more approvals than others (p<0.001). 2. With respect to the awareness of work specialty and proficiency of dental hygienist according to general characteristics, the higher the age, the higher the awareness level was. In terms of the occupational type, medical technologists were found to have higher awareness level than health professionals (p<0.001). 3. With respect to the relationship between general characteristics and view on including dental hygienists in medical personnel, the occupational type of health professional was found to have 6.33 times more oppositions than medical technologists. When the awareness level on proficiency of dental hygienist was low, opposition was 6.52 times more frequent (p<0.05). Conclusions: Based on the findings above, the inclusion of dental hygienists in medical personnel seems necessary in properly establishing the specialty and role of dental hygienist in the dentist medical environment of the country in order to enhance national oral health related preventive dental service and expand the demand.
