Purpose: The purpose of this study was to evaluate the efficacy of the modified plaque score (MPS) for assessing the oral hygiene status of periodontitis patients. Methods: A total of 116 patients were included in this study. After evaluation of the $L{\ddot{o}}e$ and Silness gingival index (GI), Silness and $L{\ddot{o}}e$ plaque index (PlI), O'Leary plaque control record (PCR), and MPS, patients were randomly assigned to either a conventional tooth brushing instruction (C-TBI) group (n=56) or a professional intraoral tooth brushing instruction (P-TBI) group (n=60). The MPS and clinical parameters were re-evaluated after scaling and a series of root planing. The convergent validity of MPS with the PlI and PCR was assessed. The measurement time for MPS and PCR was compared according to the proficiency of the examiner. Results: After root planing, the GI, PlI, PCR, and MPS improved from their respective baseline values in both groups. Three different plaque indices including the MPS, showed significant differences between the C-TBI group and the P-TBI group after root planing. The MPS showed significant concurrence with the PCR and PlI. The mean time for PCR measurement was $2.76{\pm}0.71$ times longer than that for MPS measurement after 2 weeks of training. Conclusions: MPS seems to be a practical plaque scoring system compared with the PlI and PCR. These findings suggest that repetitive plaque control combined with an easily applicable plaque index (MPS) may facilitate more effective oral hygiene education and improved periodontal health.

Purpose : As the number of patients with systemic diseases is increasing in the old, the relevance of oral health is gaining particular research interest. To provide fundamental resources for dental services, this study examined the relationship between doctors' diagnoses of circulatory diseases and patients' awareness of oral health and oral care behaviors. Methods : SPSS 26.0 was used to assess various variables, including doctor's diagnosis of circulatory diseases, gender, age, household income quintile, participation in economic activity, marital status, subjective level of oral health awareness, mastication discomfort, speaking and chewing discomfort, dental inspection, use of oral care goods, teeth brushing during the previous day, and untreated oral conditions. Results : The circulatory diseases suffered by the subjects were as follows: 56 % high blood pressure, 36 % dyslipidemia, 6 % stroke, and 8 % myocardial infarction or angina. A higher age meant a higher diagnosis rate of high blood pressure (p<.001) and stroke (p<.001). Those with dyslipidemia showed a higher rate of receiving oral inspection (p=.040), and an untreated oral condition was more frequently observed among those not diagnosed with the disease (p=.035). The subjects who were not diagnosed with stroke showed a higher rate of oral inspection (p<.001), while those who had a prior experience of stroke suffered a higher rate of mastication discomfort (p=.020). People who had high blood pressure showed a lower rate of using oral care goods (p<.001), and those diagnosed with stroke showed a lower rate of brushing teeth the previous day. Conclusion : This study found a correlation between the diagnosis of circulatory diseases and the awareness of oral health and oral care behavior. Consequently, oral health education should be included in mental health-related education, and customized training to teach teeth brushing and the use of oral care goods should be provided to patients with circulatory diseases during dentist visits.

Background: Dental caries in preschool children can cause early loss of teeth, reduced masticatory function, malocclusion, and speech disorders, making oral care for preschool children essential. However, because children have a poor ability to perform oral hygiene by themselves, educational tools that help establish correct oral health behaviors are required. This study evaluated the effect of toothbrushing application for kids on dental plaque removal and toothbrushing interest in preschool children. Methods: Seven 5-year-old children enrolled in a daycare center participated in the evaluation, and the same children participated in the experiment twice a week. The Pokémon Smile application (App) was used as an auxiliary application for tooth brushing, and the degree of dental plaque removal on the tooth surface was evaluated by quantitative light-induced fluorescence-digital imaging. After the experiment, children's toothbrushing preferences were investigated through interviews. Results: The levels of AREA R30 and AREA R70 measured after the children's toothbrushing as usual decreased compared to those before toothbrushing; however, the change was not significant. The levels of AREA R30 and AREA R70 measured after using the Pokémon Smile App were significantly reduced compared to those before toothbrushing. Children's interest in brushing their teeth increased by 28.59% after using the Pokémon Smile App. Conclusion: The toothbrushing application for kids effectively removes dental plaque by helping preschool children brush their teeth. It also increased preschool children's interest in tooth brushing. Therefore, an oral health education application would be useful for children who need to develop correct oral care methods and habits.

This study was conducted to reveal the relationship between the oral health status and their Knowledges about the oral health of the freshman of colleges in Taegu city. The evaluation for the oral health status through the oral examinations and their analysis of their knowledges on the periodontal disease were done on 216 males and 205 females from 1st to 30th April, 1993. The obtained results were as follows: The oral health status of 421 subject showed that 35.7% was good, 59.1% fair, and 6.2% poor, respectively. In case of the oral health status of females, 41.9% was good and 4.4% poor, and then in males 27.8% was good, 7.8% poor. The oral health status of the females was better than that of the males(p=0.006). The 52.1% among the good oral health status group answered that the dental plaque is the bacterial membrane causing dental disease, and the 23.1% among the poor oral health status group answered same as the above. The 91.8% among the good oral health status group answered that the periodontal diseases can be prevented, and the same answer came out from 15.4% of the poor group. It was found that the better oral health status group had the better knowledges about periodontal disease(p=0.001). For the question about their experiences in scaling the 30.1% of good oral health status group and the 23.1% of poor group answered that scaling is very helpful to periodontal health(p=0.001). About the experience of the education for tooth brushing, the 53.2% of good oral health status group and the 7.6% of poor group had the experiences to receive the education for tooth brushing(p=0.001). About the frequency and the time of tooth brushing, the 53.4% of good oral health status group brushed their teeth more then 3 times a day and 41.8% of good group brushed their teeth after every meal(p=0.001). The result of multiple regression analysis according to the simplified oral health index indicated that the variable having an effect on the oral health status was the tooth brushing frequency, knowledge of periodontal disease prevention, experience in education of tooth brushing and time of tooth brushing(p=0.001).

Objectives and Methods : The presence of aneuploidy or high proliferative activity in cytologic specimens is considered as complementary for the diagnosis of malignancy. To evaluate the diagnostic usefulness of DNA ploidy and cell cycle analysis in lung cancer, we compared the diagnostic yielding rates of DNA ploidy test by brushing specimens using flow cytometry with bronchoscopic forceps biopsy and brushing cytology. Results : Of the seventy-six cases, 55 cases proved to have malignant diseases(squamous cell cancer: 27, adenocarcinoma: 7, large cell cancer: 1, undifferentiated: 4 and small cell cancer: 16). The incidence of aneuploidy in lung cancer patients was 32.7%(18/55), as opposed to no cases in benign disease. And the proportion of high proliferative activity(S+G2M>22%) in lung cancer patients was 42.9%(15/35), but none in benign diseases. In fifty-six of 75 cases(74.7%), cytology of brushing specimens and DNA analysis(either aneuploidy or high proliferative activity vs. diploidy and low proliferative activity) were in concordance. The sensitivity with only brushing cytology was 41.8%(23/55), but with the addition of DNA analysis, it was increased to 56.4%(31/55), without decreasing the specificity(100%). And there was a case whose clue for malignancy was absent except aneuploidy, and he was confirmed to have squamous cell cancer following open thoracotomy. There were no differences in the frequency of aneuploidy or high proliferative activity between histologic subtypes of bronchogenic malignancy. Conclusions : The diagnostic detection rate of lung cancer was improved with the addition of DNA ploidy and cell cycle analysis, and the presence of aneuploidy or high proliferative activity was a relatively specific indicator of malignant disease. It would be useful to test DNA ploidy and cell cycle analysis with brushing specimen for the diagnosis of bronchogenic malignancy particularly in patients whose biopsy specimen could not be obtainable.

This study was carried out to see the effect of dental auxiliary product groups being used in case of not being able to brush teeth. This study was executed for 70 students in the Dept. of Dental Hygiene of S Health College, and it was divided into the group which used brushing teeth, the one which used only dental auxiliary products, the one which did onion juice gargle, etc, and measured the effect on the reduction of oral malodor. The experimental results of the study were as below. 1) After onion juice gargle, in the experimental group A which brushed teeth, it showed lasting decrease of oral malodor until 20min since the experiment, and after 30min, the degree of oral malodor started to increase again. 2) After onion juice gargle, the result of the experimental group B which took only supplementary products such as garglin, chewing gum, intaking green tea with roasted rice & brushing a tongue and so on, was as follows. First, in case of experimental group BG which used garglin, until 30 min has passed since the experiment, it showed the lasting reduction of oral malodor as the same trend with the experimental group BG. Second, in chewing gum (experimental group BC), intaking green tea with roasted rice (experimental group BT), and brushing a tongue (experimental group BO), continuous reduction of oral malodor was shown until 10minutes has passed since the experiment, but, after 20minutes, we could see the degree of oral malodor started to increase again. 3) After onion juice gargle, in the experimental group C which only the degree of oral malodor was measured with the passage of time, neither brushing teeth nor using auxiliary goods, until 30min since the experiment, it showed the similar trend of the reduction of oral malodor with other experimental groups, but, it showed high degree of oral malodor, as compared with other experimental groups A and B.
