Objectives: The purpose of this study was to provide basic data for gingivitis management programs by dental hygienists by evaluating the effect of oral health education, oil pulling, and professional toothbrushing on gingivitis. Methods: A total of 38 subjects were divided into three groups: control group (12 subjects), experimental group 1 (13 subjects), and experimental group 2 (13 subjects). The control and experimental groups were instructed to brush using the rotating method. Distilled water was provided to the control group after training. Coconut oil was provided every morning for about 10 minutes. In the experimental group 2, a professional brushing method was used at each visit. Results: There were no significant differences in oral health among the three groups, and there was homology between patient hygiene performance (PHP) index (p=0.144) and bleeding rate (p=0.213). The PHP index showed a significant interaction between the group and measurement time. The control and experimental groups showed changes in the PHP index with time (F=3.711; p=0.013). The bleeding rate showed a significant interaction between the group and measurement period. The control and experimental groups showed changes in the bleeding rate with time (F=6.707; p<0.001). Conclusions: Oral health education, professional toothbrushing, and oil pulling specialists in oral care of gingivitis were effective in managing gingivitis. It is necessary to educate people on self-management methods for oral health promotion using gingivitis management programs by dental hygienists.

Objectives: This study aimed to provide basic data to lay the groundwork for the introduction of an advanced dental hygienist system by sampling dental hygienists' views about the system. Methods: A nationwide questionnaire survey was conducted targeting 857 dental hygienists working at dental hospitals and clinics, local health institutions, and educational institutions. The collected data were analyzed using frequency analysis, t-test, one-way analysis of variance (ANOVA) (Duncan as post-analysis), and crossover analysis. Results: The average interest level in the advanced dental hygienist system was 3.83±0.95 points. The necessity by field was confirmed to be the highest during dental hygiene for the elderly and persons with disabilities. The working experience necessary for becoming a specialized dental hygienist is 5.56±2.99 (years). The education period necessary for becoming a specialized dental hygienist is 77.30±77.61 (hours). The work authority level for an advanced dental hygienist was indicated to be 50 respondents (5.8%), who said they required direct guidance from a dentist, 313 respondents (48.2%) who said they needed indirect guidance from a dentist, 200 respondents (23.3%) who said OK when given an advanced dental hygienist's separate judgment, 194 respondents (22.6%), who said that the authority must be varied depending on the work. Conclusions: The interest and need of the advanced dental hygienist system were proven to be high and are expected to be applied to basic data for the introduction and settlement of the system.

Background and Objectives Vocal polyp is one of the most common benign diseases of vocal fold caused by overuse of voice. Laryngeal microsurgery is the first treatment of choice for vocal polyp. However, surgery has many risks such as side effects of general anesthesia, injury of tooth and psychological burden. And we often experience reduction of vocal polyps without surgical procedure. The purpose of study is to evaluate the effect of non-surgical treatment such as vocal hygiene education and proton pump inhibitor (PPI) in patients with vocal polyp. Materials and Method We performed retrospective study for seventy-three patients of vocal polyp who treated with non-surgical modalities such as vocal hygiene education and PPI over three months. Treatment outcomes and risk factors such as age, sex, polyp size, position, symptom duration, presence of laryngopharyngeal reflux (LPR) symptoms, smoking history, voice abuse history and vocal hygiene education were evaluated by comparison between polyp size improved group and non-improved group. Results 5.5% of enrolled patients showed complete response and 23.3% showed partial response without surgery. Polyp size improved group significantly carried out more practice of vocal hygiene education treatment than the non-improved group (p=0.040). And the presence of LPR symptoms [hazard ratio (HR) 3.368, confidence interval (CI) 1.055-10.754, p=0.040] and not performing of vocal hygiene education (HR 3.664, 95% CI 1.078-12.468, p=0.038). Conclusion Vocal hygiene education can be a useful treatment option when making a decision to treat with vocal polyp.

To assess biological indoor air quality in hospital, concentrations of viable airborne microbes were determined at intensive care unit(ICU), patient room (PR), outpatient waiting room(OPWR) in hospitals of large(1000 beds), middle(500 beds), small(100 beds) hospitals, respectively. Gram positive bacteria, gram negative bacteria, fungi were sampled using suctional sampling method by RCS sampler (Reuter centrifugal air sampler) and RCS GK-A agar plate. In gram positive bacteria groups, CNS(Coagulase Negative Staphylococcus), Micrococcus, Lactobacillus, S. aureus, Enterococcus, St. viridans identified. In gram negative bacteria groups, A. baumannii, Kl. peumoniae and E. coli were identified, and Penicillium was identified in fugi groups. Results of the study were as follows. 1. The highest concentrations of airborne microbes was $971CFU/m^3$ at 5:00 PM in small hospital patient room, and average concentrations of airborne microbes in large, middle and small hospitals were $282CFU/m^3$, $289CFU/m^3$ and $625CFU/m^3$, respectively. Average concentrations of airborne microbes in office(control) was $90CFU/m^3$. Thus, the small hospital showed the worst condition. 2. Representatives of 8 different genera were identified in 150 samples. The most frequently isolated organisms were Staphylococcus (73.0%), Micrococcus (20.7%) and Lactobacillus (4.7%), respectively. Pathogenic microbes isolated were A. baumannii, E. coli, Enterococcus, Kl. peumoniae, S. aureus, St. viridans and Penicillium as fungi. In office, no pathogenic microbes were identified. Average concentrations of airborne pathogenic microbes in large, middle and small hospital were $5CFU/m^3$ (2%), $11CFU/m^3$ (4%) and $12CFU/m^3$ (2%), respectively. Thus, condition in a large hospital was better than those in a middle and a small hospital.

The objective of this study is to provide fundamental data for pertinent management of indoor air quality through investigating the size-based characteristics of bioaerosol distributed in the general hospital. Measurement sites are main lobby, ICU, ward and laboratory and total five times were sampled with six-stage cascade impactor. Based on the result of this study, concentrations of airborne bacteria and fungi were the highest in main lobby as followed by an order of ward, ICU and laboratory. Concentrations of airborne bacteria was generally higher than those of airborne fungi and the ratio of indoor and outdoor concentration of both exceeded 1.0 in all the measurement sites of the general hospital. The predominant genera of airborne bacteria identified in the general hospital were Staphylococcus spp.(50%), Micrococcus spp.(15-20%), Corynebacterium spp.(5-20%), and Bacillus spp.(5-15%). On the other hand, the predominant genera of airborne fungi identified in the general hospital were Cladosporium spp.(30%), Penicillium spp.(20-25%), Aspergillus spp.(15-20%), and Alternaria spp.(10-20%). In regard to size distribution of bioaerosol, the detection rate was generally highest on 5 stage($1.1-2.1{\mu}m$) for airborne bacteria and on 1 stage(>$7.0{\mu}m$) for airborne fungi. Cleanliness of facilities in the general hospital and condition of HVAC system should be monitored regularly to prevent indoor air contamination by airborne microorganisms.
