Purpose: The goal of this study was to characterize the patterns of antimicrobial resistance and virulence genes in samples of Staphylococcus aureus (S. aureus) isolated from periodontitis patients. Methods: From July 2015 to August 2015, oral saliva was collected from a total of 112 patients diagnosed with periodontitis, including 80 outpatients in dental hospitals and 32 patients in dental clinics located in Seoul and Cheonan. The samples were subjected to a susceptibility test to evaluate the prevalence of antimicrobial resistance, and the pathogenic factors and antimicrobial resistance factors in the DNA of S. aureus were analyzed using polymerase chain reaction. Results: A susceptibility test against 15 antimicrobial agents showed that 88% of cultures were resistant to ampicillin, 88% to penicillin, and 2% to oxacillin. Resistance to at least two drugs was observed in 90% of cultures, and the most common pattern of multidrug resistance was to ampicillin and penicillin. Enterotoxins were detected in 65.9% of samples. The cell hemolysin gene hld was detected in 100% of cultures and hla was detected in 97.6% of samples. All strains resistant to penicillin and ampicillin had the blaZ gene. The aph(3')IIIa gene, which encodes an aminoglycoside modifying enzyme, was detected in 46.3% of samples. Conclusions: In the treatment of oral S. aureus infections, it is important to identify the pathogenic genes and the extent of antimicrobial resistance. Furthermore, it is necessary to study patterns of antimicrobial resistance and cross-infection in the context of periodontological specialties in which antimicrobials are frequently used, such as maxillofacial surgery, where the frequency of antimicrobial use for minor procedures such as implant placement is increasing.

The purpose of this study was to examine the impact of the DISC behavioral patterns of health care workers on their job satisfaction, organization Commitment and job stress in a bid to suggest an ideal behavioral pattern of Nurses and Dental hygienist. The subjects were 184 health care workers who worked in general hospitals and clinics in Busan and Ulsan for a year or more. The collected data were analyzed using ANOVA and linear regression. As a result of analyzing the relationship of their DISC behavioral patterns to job stress, organizational satisfaction and organizational commitment, there were significant differences in job stress according to their DISC behavioral patterns(p=0.015). In regard to relationship between their DISC behavioral patterns and the subfactors of job stress, there were significant gaps in role conflicts(p=.007), conflicts with subordinates(p=0.001) and conflicts over underpayment(p=0.015) according to their DISC behavioral patterns. As a result of investigating the influential factors of job stress, factors produced significant results(p<.001). The findings of the study illustrated that out of the DISC behavioral patterns, type I was most prevailing among the health care workers, which indicated that the weight of this type was highest among the behavioral styles. There were no significant gaps in job satisfaction and organizational commitment according to their DISC behavioral patterns.

The purpose of this study was to examine the relationship of the general characteristics of dental patients to their total O'Leary index and individual plaque indexes in a bid to check the oral hygiene state of citizens and evaluate their plaque management ability. The subjects in this study were 288 patients at dental hospitals and clinics in Busan and South Gyeongsang Province. A survey was conducted from September to November 2008. The findings of the study were as follows: 1. Overall, the O'Leary index of the patients investigated stood at 72 percent. By age and gender, the O'Leary index was highest among those in their 30s(83%) and among the women(75%)(p<.05). As to the influence of toothbrushing frequency, the patients who did it twice or more a day had the highest O'Leary index(75%)(p<.001). By the use of oral hygiene supplies, the patients who used oral hygiene supplies had a higher O'Leary index(76%) than the others who didn't(p<.01). 2. As for plaque index for each tooth, 28 percent of their teeth were given zero point, and 52 percent were given one mark. 13 percent were given two marks, and 6.3 percent were given three marks. Thus, the teeth that were given one mark were largest in number(p<.001). 3. As for plaque index for labial posterior mandibular, 43 percent of their teeth were given one point, and 36 percent were given zero mark. 14 percent were given three mark, and 5 percent were given three marks(p<.01). 4. As for plaque index for buccal posterior maxilla, 57 percent of their teeth were given one point, and 20 percent were given zero mark. 16 percent were given two mark, and 6.3 percent were given three marks(p<.01). 5. As for plaque index for lingual posterior mandibular, 56 percent of their teeth were given one point, and 27.8 percent were given zero mark. 9 percent were given three mark and 6 percent were given three mark(p<.001).

Though oral microgranisms were among the first to be observed by humans, the interest in oral microbiology lagged. When it became apparent that the oral microflora did influence systemic disease of the body, interest was aroused in the nature and kinds of the microgranisms. The risk of infection in dental procedures is due to the abundant flora of the mouth. This hazard can be reduced to some extent by the use of a local disinfectant. The present studies were undertaken to evaluate and compare the various disinfectants which are commonly used in clinics and hospitals. The results were as follows. 1. The bactericidal activity of the disinfectants mainly depends upon the kinds of the agents, not upon the kinds of the microorganisms. 2. In H₂O₂(3%), the bactericidal activity was greatly related to the contact time. So, at least 4 minitues of contract time was required to use it as an oral antiseptic. 3. In ethyl alcohol (70%), Pseudomonas aeruginosa and Streptococcus salivarius surived a little after 15 seconds of contact time, but, no other colony was discovered after more than 15 seconds of contact time in any kins of microorganisms. 4. Merthiolate (0.1%) showed low antibacterial activity, more in Gram-positive organisms and less in Gram-negative organisms. 5. Benzalkonium chloride (0.1%) and povidone-iodine (10%) showed the most excellent results, revealing no surviving organisms only after 14 seconds of contact time.

Methods : The subjects in this study were personnels who were selected by random selection in five different special schools located in the city of Jeonju, North Jeolla Province. A self-administered survey was conducted in person from July 5 to 14 after the purpose of this study was explained. Results : 1. Concerning their general characteristics, the level of oral health knowledge was high in the personnel whose career is 5 years more, and the younger personnels had a better oral health knowledge, and the men were more knowledgeable than the women. 2. As to oral health education experience, the rate of the respondents who ever received oral health education stood at 35.3 percent. In relation to the frequency of oral health education, the biggest group that accounted for 58.2 percent received that education once. As for the route of education, the largest group that represented 52.7 percent received that education at dental hospitals or clinics. In relation to satisfaction with oral health education, the greatest group that accounted for 38.5 percent were dissatisfied with that education. 3. As for an intention of receiving oral health education in the future, the biggest group that accounted for 60.9 percent intended to receive that education if they would have free time, and the largest group that represented 47.7 percent believed that oral health education should be conducted by dental hygienists. 4. Concerning their general characteristics, the level of oral health promotion behavior according to age in both bushing and supplies of oral health care was high in forties-1.89 point and 3.33 point, and that in regular visit to a dental clinic was the highest in twenties for 2.58 point, and that in dietary control was the highest in twenties for 2.59 point. 5. Their oral health knowledge had a significant positive correlation to their toothbrushing, regular dental clinic visit and dietary control that were the subfactors of oral health promotion behavior. 6. As for the impact of oral health promotion behavior on oral health knowledge, toothbrushing exerted the greatest influence on that(${\beta}$=0.306, p<0.001). Conclusions : Appropriate institutional measures should be taken to let dental hygienists who are expert in oral health care provide incremental oral health care for students and adults with disabilities in educational institutions and facilities for the disabled, and the development of oral health education programs is urgently required to offer systematic oral health education for not only students with disabilities but their teachers and guardians.
