This study was performed to investigate the microbiological contamination on toothbrushes, toothbrush caps, and tooth cleaning cups in the child care centers and to evaluate the toxin genes, toxin production ability and antibiotic resistance of food-borne pathogens. The average number of total aerobic bacteria and fungi were 5.3 log CFU and 3.2 log CFU. Coliform bacteria were detected in 41 (54.7%) of 75 toothbrushes, 13 (44.8%) of 29 toothbrush caps, and 29 (44.6%) of 65 tooth cleaning cups. Salmonella spp. was not detected in all of samples but Bacillus cereus was isolated from 1 (1.3%) of 75 toothbrushes and 2 (3.1%) of 65 tooth cleaning cups. Staphylococcus aureus was detected in 1 (1.5%) of 65 tooth cleaning cups. The nheA, nheB, nheC, hblC, hblD, hblA and entFM toxin genes were possessed in B. cereus isolated from toothbrush which also produce NHE and HBL enterotoxins. S. aureus was resistant to ampicillin and penicillin, while B. cereus was resistant to ${\beta}-lactam$ antibiotics. These results indicated that the sanitary conditions of toothbrushes and tooth cleaning cups in the child care centers should be improved promptly. The UV sterilization after drying and then storage in dried condition is required to improve the sanitary condition of toothbrushes and tooth cleaning cups in the child care center.

The study was to expand the choice of electric toothbrush by number of operations of the plaque removal effect on the tooth surface. Three different toothbrushes were selected for oscillations and pulsations type of electric toothbrush. A is Oral-B D12 (7,600 pulsations), B is Oral-B D16 (20,000 oscillations and a 7,600 pulsations), C is Oral-B D20 (40,000 oscillations and an 8,800 pulsations). In each trial, each tooth was brushed for 2 seconds. For the 10 trials. And each tooth was coated with 1layer, 2layers and 3layers. After the experiment, the plaque removal effect was calculated and analzed using the Image J program(p<0.05). According to the study, C toothbrush had the highest rate of plaque removal effect. Based on this results of the study, dental worker will need to evaluate oral hygiene and recommend appropriate toothbrushes according to oral conditions.

This study aimed to compare the elimination effect of dental plaque between general toothbrushes and chewing toothbrushes, so as to investigate whether the chewing toothbrushes have the practicality as the alternatives of general toothbrushes and their utilities in the real life. The study subjects were 30 healthy adults in their 20s who maintained the good dental condition over 16 teeth without systemic diseases, and the decline rates of dental plaque index after usages of general and chewing toothbrushes were calculated. Upon the comparisons of dental plaque decline rates before and after the usages of general and chewing toothbrushes, PHI index was declined from 7.02 to 1.91 in case of the general toothbrush demonstrating dental plaque decline by 72.79%, while it was declined from 6.72 to 4.08 in the chewing toothbrush demonstrating decline by 39.29%. Currently, a variety of dental care items are available in the Korean market, hence, various studies are required on the dental care items so as for the people to properly choose the items.

Foreign bodies of the parapharyngeal space can cause severe complications such as descending suppurative mediastinitis, jugular thrombophlebitis, cavernous sinus thrombosis and carotid erosion. Therefore, early diagnosis and surgical intervention are needed to reduce morbidity and mortality. We present a case of a toothbrush as foreign body in the parapharyngeal space in 28-year-old male patient. The tooth brush was broken and the remnant of that was left in the patient's mouth. Under general anesthesia, intraoral approach was undertaken and successfully the toothbrush was removed, and then incision and drainage was done by transcervical approach. We report this case with review of literature.

Objectives : TThe purpose of this study was to examine the relationship between the oral health education experience of workers and their oral health awareness in an attempt to provide some information on corporate oral health education plans. Methods : The, subjects in this study were 230 workers in Busan and South Gyeongsang Province, on whom a self-administered survey was conducted from August, 2010, to June 18, 2011. A frequency analysis was carried out to grasp the general characteristics of the 205 respondents, and x2-test(p). Results : 1. As for the relationship of the oral health education experience of the workers and their awareness of toothbrush involving optimum toothbrush size, 47.4 percent of those without educational experience thought that a toothbrush should be large enough to cover about two teeth(p<.018). 2. Regarding the relationship between the oral health education experience of the workers and their awareness of fluoride, 59.1 percent of the respondents with educational experience perceived that dentifrice contained fluoride(p<.05). 3. Concerning the relationship between the oral health education experience of the workers and their awareness of periodontal diseases including the cause of the diseases, 43.6 percent of the respondents with educational experience(p<.021). 4. As to the relationship between the oral health education experience of the workers and their awareness of scaling, 50.2 percent of the respondents with educational experience and gingival diseases(p<.037). 5. In terms of the relationship between the oral health education experience of the workers and their awareness of toothbrushing involving toothbrushing frequency, 36.8 percent of those without it considered it necessary to do toothbrushing three times a day(p<.045). Conclusions : The above-mentioned findings illustrated that there were differences among the workers in oral health awareness according to their oral health education experience. Therefore the development of systematic oral health education programs is required to promote the oral health of workers.
