  • This study purposed to survey D university students' perception of kindness in their use of dental care services in an area of Gyeonggido. For this purpose, we conducted a questionnaire survey of 502 students from October 2, 2008 to March 6, 2009 and analyzed the data. Results obtained from this study are as follows. 1. Of the subjects, 71.3% were female, 67.7% were at the age of 20 or younger, and 89.2% had experience in visiting a dental clinic. Among the subjects who had experience in visiting a dental clinic, 31.1% replied that they were highly interested in oral health, and to the question on the selfperceived current oral health condition, 35.1% replied that there was something wrong in their oral health condition. 2. With regard to correlation between general characteristics and interest in oral health, 79.9% of the male subjects and 83.2% of the female ones were highly interested in oral health. According to age, interest in oral health was highest among those aged 26 or older 92.0%. 3. With regard to correlation between general characteristics and oral health condition, if the presence of dental caries or periodontal disease was considered an indicator of poor oral health, 66.0% of the male subjects and 70.9% of the female ones appeared unhealthy, 72.0% of students aged 26 or older showed satisfaction. 4. The most frequent reason for not visiting a dental clinic was 'Not sick' 34.6%, and among those who had experience, the most frequent reason for visiting was 'To get treatment of sick teeth' 63.0%. With regard to the perceived kindness of dentist and dental hygienist, 40.6% and 45.8% of the subjects, respectively, were highly satisfied. The most frequent reason for satisfaction was 'Comfortable with patient reception' 34.4% and the most frequent reason for dissatisfaction was 'Explain treatment insufficiently' 30.7%. 5. As to perceived kindness according to gender, 60.9% of the male subjects and 56.1% of the female ones were satisfied with dentist's kindness, and 66.9% and 59.6%, respectively, were satisfied with dental hygienist's kindness. According to age, 62.5% of students aged 26 or older showed satisfaction with dentist's kindness and 78.3% of them with dental hygienist's kindness. 6. As to perceived kindness according to correlation between interest in oral health and current selfperceived oral condition, the kindness of dentists(68.0%) and hygienists(67.8%) was perceived higher when interest in oral health was high and not very interested and the kindness of dentists(50.0%) and hygienists(66.78%) when selfperceived oral condition was healthy, and the difference was statistically significant (p<.022 and p<.023, respectively).

  • This study was carried out to investigate recognition level and practical application status of oral hygiene devices through making a survey of Seoul inhabitants. And survey was implemented in order to propose oral hygiene device for household health care activities. The following results were obtained by analyzing personal interviews of 347 commuting patients at two university hospitals and seven dental clinics. 1) The average length of toothbrush head was estimated as 22.3 mm and average changing cycle was 2.3 months. The user ratio of flat-headed brush was estimated as 51.9% and 46.7% were using fluoridated toothpaste. 2) Generally the ratio of toothpick users was higher than other device users. But the user ratio of dental floss was higher than toothpick in case of patients under orthodontic treatment. 3) The patients under orthodontic treatment were not familiar with handling orthodontic toothbrush. Though 45.8% among orthodontic patients recognized this type of toothbrush, only 25.4% of them knew how exactly to use it. 4) It was shown very low user ratio of oral hygiene devices that the patients who had periodontal problem, hypersensitive trouble, halitosis, implant or denture 5) The patients who had halitosis showed the highest user ratio of toothpick. The patients who had separation of teeth showed the highest user ratio of dental floss. The patients who're under orthodontic treatment showed the highest user ratio of interproximal brush and motorized brush. 6) In response to the most interesting dental disease, it's surveyed as follows; 60.3% of dental caries, 24.0% of periodontal disease, 14.8% of false occlusion and 0.9% of oral cancer. 7) Regarding the motivation of using those oral hygiene devices, 45% responded that it was because of recommendation by dental clinics. Among the negative answers, 38.6% responded that it was because of no selection guidance. 31.3% answered that they didn't use hygiene device because it's inconvenient. 12.0% answered that it's difficult to buy and expensive. 7.8% responded that they didn't feel significant improvement. 4.8% answered that dental hospitals and clinics didn't even introduce those hygiene devices. Therefore efficient campaign for those hygiene devices over all Korea nation should be developed and education program must be prepared for each case of patients in every dental hospitals and clinics.

  • Statement of problem: Restoring and replacing teeth with fixed prostheses commonly used in dental practice. Because of improper oral hygiene care and inaccurate laboratory procedure, complications of fixed prostheses were found in the mouth of patients. Although many efforts have been continually made to obtain the data of long term prognosis of fixed prostheses, it was difficult to do it. Purpose: The purpose of this study was to evaluate the clinical status of fixed prostheses. Material and methods: In order to assess the clinical status of fixed prostheses, a total of 161 individuals(aged 17-85, 99 women and 62 men with 1596 unit of fixed prostheses, and 1169 abutments) who first visited the Department of Prosthodontics, Pusan National University Hospital, between April to September, in 2007 were examined. Results and conclusion: The results of this study were as follows: 1. Length of service of fixed prostheses was $8.6{\pm}0.6$ years(mean), 10.0 years(median). 2. Location of fixed prostheses was found to have no statistically significant influence on longevity of fixed prostheses(P>.05). But, the success rate was high in posterior region and in mandible where the failure rate was high in combination(P<.05). 3. Longevity of fixed prostheses made of metal was longest(mean: $13.0{\pm}9.3$, median: 14.0), gold, precious ceramic, non-precious ceramic trailing behind(P<.05). 4. Number of units in fixed prostheses was found to have no statistically significant influence on longevity of fixed prostheses(P>.05). But, the success rate was high in Single-unit and the failure rate was high in over 3-unit(P<.05). 5. Condition of opposing dentition was found to have no statistically significant influence on longevity of fixed prostheses(P>.05). But, the success rate was high in natural dentition(P<.05). 6. Defective margin(28.2%), dental caries(23.0%), periodontal disease(19.3%), periapical disease(16.9%) were frequent complications. In 30.1% of the cases, abutment state after removing fixed prostheses was needed to be extracted.

  • This study was undertaken to evaluate the clinical effect of inhibiting plaque formation of Lactococcus lactis 1370, a acid producing bacterium residing in the mouth. 30 children were asked to use 10ml of control mouth-wash and mouthwash containing Lactococcus lactis 1370. The plaque index and plaque area rate at 24h and 48h after the use of the mouthwashes were measured. And the number of Lactococcus lactis 1370 was counted at 1h, 3h, and 6h in the mouth. The results are as follow. 1. The mean plaque index at 24h after the use of the control mouthwash and the mouthwash containing Lactococcus lactis 1370 were 2.43 and 2.06, respectively. The inhibiting rate of plaque formation was 15% (P<0.05). 2. The mean plaque index at 48h after the use of the control mouthwash and the mouthwash containing Lactococcus lactis 1370 were 2.95 and 2.17, respectively. The inhibiting rate of plaque formation was 26%, showing more decrease than at 24h(P<0.05). 3. The mean plaque area rate at 24h after the use of the control mouthwash and the mouthwash containing Lactococcus lactis 1370 were 21.2% and 15.6%, respectively. The inhibiting rate of plaque formation was 26% (P<0.05). 4. The mean plaque area rate at 48h after the use of the control mouthwash and the mouthwash containing Lactococcus lactis 1370 were 33.0% and 17.8%, respectively. The inhibiting rate of plaque formation was 46% (P<0.05). 5. The number of Lactococcus lactis 1370 in the mouth decreased significantly from mouthwashing to 3h, but increased slightly between 3h and 6h. As seen with the above results, we think that using the mouth wash with Lactococcus lactis 1370 would prevent the formation of plaque in the mouth and can be an effective method to prevent dental caries and periodontal disease.

  • Recently it is very interesting that the plant extracts use to prevent or treat the oral diseases. The present study was performed to observe the antibacterial effect on S. gordonii Challis, S. gordoii G9B, S. mutans GS5, S. sobriuns 6715, E. faecalis ATCC 4083, A. actinomycetem Y4, P. gingivalis A7A1-28, P. gingivalis W83, Pr. intermedia ATCC 25611, F. nucleatum KTCT 2488, C. albicans ATCC 18804 of Artemisa capillaris THUNB employing the viable cell counts. The results were as follows: 1. Minimum inhibitory concentration(MIC) and Minimum bactericidal concentration(MBC) of extracts of Artemisa capillaris THUNB for P. gingivalis A7A1-28, P. gingivalis W83, and Pr. intermedia ATCC 25611, which are the pathologic bacteria of periodontal diseases, was observed under 2%. 2. MIC of extracts of Artemisa capillaris THUNB for P. gingivalis A7A1-28 was determined to be 1.2% and MBC was determined to be 2.0% respectively. 3. MIC of extracts of Artemisa capillaris THUNB for P. gingivalis W83 was determined to be 1.4% and MBC was determined to be 2.0% respectively. 4. MIC of extracts of Artemisa capillaris THUNB for Pr. intermedia ATCC 25611 was determined to be 1.2% and MBC was determined to be 2.0% respectively. The overall results indicate that Artemisa capillaris THUNB used for this study has a strong antibacterial activity against P. gingivalis A7A1-28, P. gingivalis W83, and Pr. intermedia ATCC 25611, which are the periodontopathic bacteria. Therefore, the extracts of Artemisa capillaris THUNB can be used as a candidate for prevention and therapeutic agent against periodontal diseases.

  • As oral diseases are developed by mixed infections, not by any single element, an accurate analysis of the causative microorganisms related to dental caries and periodontal diseases is required. In this study, saliva was collected from selected adults to determine if the bacteria that are well known as the causative microorganisms of dental caries and periodontal diseases would be detected in their saliva. In addition, this study examined whether there would be any differences among adults according to age, smoking, drinking and presence or absence of diseases in the distribution of oral bacteria to determine the risk factors for oral bacteria. The study subjects were 120 adults ranging in age from 20 to 65 years. The experiment data was collected from March 15, to May 2014. The gDNA was collected from the saliva, and the distribution of bacteria for oral diseases was investigated by PCR. The findings of the study were as follows. S. mutans was detected from 72 adults, and P. intermedia was detected from 88 adults. Both bacteria were detected from 54 adults, and no oral bacteria was detected in 14 adults. An analysis of the risk factors of oral bacteria showed that smokers had a 2.8-fold higher risk of S. mutans than nonsmokers, and the former had a 3.5-fold higher risk of P. intermedia than the latter. Drinkers had a 3.3-fold higher risk of S. mutans than nondrinkers. Patients who suffered from systemic diseases had a 4.1-fold higher risk of P. intermedia than those with no diseases. Therefore, smoking, drinking and systemic diseases are factors that increase the likelihood of oral bacteria detection. More periodontal disease bacteria were detected from older adults, and more oral bacteria were found in adults who were in their 20s, as dental caries and periodontal diseases were more common in this age group. The adults in which oral bacteria were detected are more likely to have dental caries or periodontal diseases, and they should try to keep their mouth cavity clean and make regular visits to a dental clinic to prevent possible oral diseases.

  • This study is to look at the risk of chronic diseases in adults and oral health behaviors affecting periodontitis by gender. This study selected 3,071 males aged 35 to 65, 4,273 females, and 7,344 people as the final subjects of the study using the sixth original data from the National Health and Nutrition Survey. In this study, subjective oral health classified under 'bad' presented 1.69 times(p<0.001) the risk of Periodontitis for males and 1.50 times(p<0.001) for females. There was a 2.01 times(p<0.001) of a risk of periodontitis for male and 1.40 times(p=0.001) of a risk for females. Smokers have a 1.68 times(p<0.001) of a risk for males and 2.07 times(p<0.001) of a risk for females, thus a higher risk for periodontitis for females. The risk of periodontitis was 1.44 times(p<0.001) of a risk for males and 1.30 times(p<0.05) for females when compared in normal hypertension. Obesity was at a rate of 1.199 times(p<0.05) as much for males in the non-military group, 1.202 times(p<0.05) that of females for periodontitis and putting females slightly more at risk. For diabetes, males were at risk of 1.28(p<0.05) whereas it being 1.53 times(p<0.05) for females, compared the average health female. In total, Males were found to be at the greatest risk of periodontitis, while women were at the highest risk for smoking. All parameters except smoking and diabetes show a higher risk of periodontitis for females. As males are more likely to have a higher risk of periodontitis than females, they are considered to be more interested in oral health care and need systematic oral health education and policies to prevent oral diseases.

  • An ideal anti-bacterial medication for oral infection requires selective effect on pathogens causing dental caries and periodontal disease but not on normal flora. In addition, it should be less toxic for human and even for environment. This study was to seek such a natural anti-bacterial medication and thus anti-bacterial effect of Hamamelis virginiana was evaluated. Many recent researches on the anti-bacterial effect of natural plant extract and essential oil have reported that natural products can be used as medication for prevention and restrainment of dental caries, halitosis and periodontitis. It has been also reported that Hamamelis virginiana has anti-bacterial effect on Porphyromonas gingivalis, Fusobacterium nucleatum, Capnocytophaga gingivalis, Veilonella parvula, Eikenella corrodens, Peprostreptococcus micros, and Actinomyces odontolyticus. This study evaluated anti-bacterial effect of Hamamelis virginiana on Streptoccoccus mutans, Haemophylus actinomycetemcomitans, and Klebsiella pneumoniae to expand its anti-bacterial effect on other important oral pathogens and eventually to develop its oral care products or apply to clinical purpose. In this study, anti-bacterial tests for antibiotic disk susceptibility, minimal inhibitory concentration and minimal bactericidal concentration were performed to evaluate anti-bacterial effect of Hamamelis virginiana against Streptoccoccus mutans, Haemophylus actinomycetemcomitans, and Klebsiella pneumoniae. The results showed that Hamamelis virginiana has anti-bacterial effect on all pathogen strains tested in this study and furthermore Hamamelis virginiana possesses bactericidal effect other than bacteriostatic effect on Streptoccoccus mutans, Haemophylus actinomycetemcomitans, Klebsiella pneumoniae. This study indicates that a natural anti-bacterial medication for oral diseases can be developed using Hamamelis virginiana.

  • In this research, dental health awareness of 3rd graders of high schools in Icheon-city was investigated in order to use the result of this research as the basic data for school dental health program, education direction, and educational purpose. The research was done from Sep. 23. to Oct. 5 and the followings are the results of survey. (1) 85.0% of the students brush their teeth once or twice a day and more female students brush their teeth 3 times a day than male students. (2) 77% of the students had experienced dental caries and 38.0% of the students have periodontal disease, which has lower percentage than cavity. (3) Most of the students can not go to the dentists because they do not have time and 84.0% of the students have been treated in dental clinics so this tells that most of the students had experienced dental treatment. (4) 46.8% of the students had interests in dental health and male students showed more interests than female students and the difference was statistically significant(p<0.05). (5) Most of the students hear the importance and information of dental health from mass media such as TV and radio or from people around. The research shows that most of the students do not get periodic dental checkups. (6) 80.8% of the students had never taught dental health education for improvement of dental health and 76.2% of the students think that the dental health education is needed. There was no difference according to the gender. (7) Most of the students think that the dental health education is needed to prevent cavity and gingiva disease and it shows that more students tend to attend the dental health education. (8) 69.3% of the students think that brushing your teeth is important to maintain good dental health and there was no difference according to the gender. Most of the students weren't aware that periodic dental checkups, right brushing, and using fluoric toothpaste is effective for cavity protection. (9) After looking into the knowledge of the students on dental health, it shows that the knowledge is low and there is no difference according to the gender.
