OBJECTIVE: The purpose of this study was to evaluate the efficacy of a slim bristled toothbrush compared with a V-shaped orthodontic toothbrush in patients with fixed orthodontic appliances. METHODS: Thirty four orthodontic patients receiving edgewise treatment were randomly assigned to two groups, a slim bristled toothbrush (Nano silver slim care) and a V-shaped toothbrush (Oral-B). Plaque index, gingival index and bleeding index were recorded at the beginning of the study (baseline), 2 weeks, 4 weeks and 6 weeks after new toothbrushes were supplied and the results were analyzed statistically. RESULTS: No statistically significant differences were found for plaque index, gingival index and bleeding index between toothbrush groups during the 6 weeks. Plaque and gingival indices were decreased at 2 weeks and 4 weeks but increased at 6 weeks in both toothbrush groups. Bleeding index in the V-shaped toothbrush group showed the lowest value at 2 weeks then increased at 4 weeks and 6 weeks but in the slim bristled toothbrush group decreased from 2 weeks through 6 weeks to under baseline levels. Patients in their twenties had significantly lower values than teenagers in the slim bristled toothbrush group (p < 0.013). CONCLUSIONS: The results would suggest that both of the toothbrushes are equally effective but the use of a slim bristled toothbrush may be of benefit in promoting gingival health for fixed orthodontic appliance patients in their twenties and over.

The purpose of this study was to evaluate the efficacy of an electric toothbrush, with a specially designed orthodontic brush head, compared to a manual toothbrush on the periodontal health of patients with fixed orthodontic appliances. Forty patients were randomly divided into two groups, the electric and the manual toothbrush groups, 1 month after attachment of fixed orthodontic appliances. Periodontal status was measured using a plaque index, a gingival index, a bleeding index, a pocket depth and a relative attachment loss, at baseline and after 3 months, 6 months, 9 months, and 12 months. The Braun Oral-B Plak Control with Ortho OD 15-1 brush head was used as the electric toothbrush while the Butler G.U.M 124 was given as the manual toothbrush. In the manual toothbrush group, the gingival and bleeding indices showed no statistically significant differences, but the plaque index was significantly decreased (p < 0.001) and pocket depth as well as relative attachment loss were significantly increased (p < 0.01). In the electric toothbrush group, the bleeding index, pocket depth and relative attachment loss showed no statistically significant differences, but the plaque and gingival indices were significantly decreased (p < 0.001). In the case of the plaque, gingival and bleeding indices, there were no statistically significant differences between the electric and the manual toothbrush groups. On the contrary, in the case of pocket depth and relative attachment loss, there were statistically significant differences between the electric and the manual toothbrush groups: an increase in the manual toothbrush groups unlike the electric toothbrush group which kept the same state (p < 0.05). These findings suggest that an electric toothbrush is useful for orthodontic patients with fixed appliances.

Patients with fixed orthodontic appliances frequently have increased levels of plaque accumulation leading to the possibility of gingivitis or enamel decalcification. Although many methods may be helpful in reducing dental plaque formation, the optimal mechanical removal of plaque is the most important factor during orthodontic treatment. The purpose of this study was to evaluate the efficacy of an electric toothbrush (with a specially designed orthodontic brush head) compared to a manual toothbrush in controlling plaque and gingivitis for patients with fixed orthodontic appliances. Oral hygiene status was measured in thirty-four patients using a plaque index, a gingival index and a bleeding index, before and four weeks after the attachment of fixed orthodontic appliances. Patients were randomly divided into two groups: electric and manual toothbrush groups. Oral hygiene instruction was given according to the type of toothbrush used. The Braun Oral-B D9511 with Braun Oral-B Ortho OD 15-1 brush head was used as the electric toothbrush while the Butler G.U.M. 124 was given as the manual toothbrush. After four and eight weeks, oral hygiene status was measured again. Through a comparison between the electric and the manual toothbrush groups, the following results were obtained. 1. All oral hygiene indices showed an increasing tendency after four weeks of fixed orthodontic appliance. 2. All indices presented a decreasing tendency four and eight weeks after oral hygiene instruction. 3. In case of the gingival index and bleeding index, the decreasing tendency did not show a statistically significant difference between the electric and the manual toothbrush groups. 4. The decreasing tendency of plaque index presented a statistically significant difference between the two groups, showing that the electric toothbrush was more effective in terms of oral hygiene. These findings suggest that an electric toothbrush is useful to orthodontic patients with fixed appliances.

OBJECTIVES: The aim of this study was to compare short-term and medium-term effects of gingival index (GI) and dental plaque index (PI), according to the tooth position through the oral hygiene education in the diabetic youth. METHODS: The total number of participants were 31 diabetics and 87 controls in the city of Daegu. Oral examination and professional oral hygiene care were performed among the 31 diabetic youth who consented to the study at the first visit. The professional oral hygiene care consisted of the tooth brushing method, oral prophylaxis, scaling, fluoride application, sealant and dental auxiliary education. We collected the data from all participants for the identification of oral condition at 2 weeks and 3 months. The #11, #14, #16, #31, #34, #36 teeth were selected for the measurement of the oral hygiene conditions. GI and PI were used for oral hygiene scores. The data was analyzed with SPSS 18.0 program. RESULTS: Both GI and PI were significantly decreased in the treatment group of the 31 diabetic youth in comparison to the controls, by tooth position compared to the baseline (P<0.001). In particular, GI measurements constantly decreased upto 3 months and the PI measurements decreased upto 2 weeks and increased slightly from 2 weeks to 3 months. In the GI measurements, the decrement of #14 was the highest (48.4%) and #36 was the lowest (25.2%) among all teeth. In the PI measurements, the decrement of #14 was the highest (45.5%) and #16 was the lowest (19.8%) among all teeth. In the control group, PI increased on all tooth positions, and GI increased on some tooth positions. CONCLUSIONS: The program of professional oral hygiene care in the diabetic youth has improved the oral health care when compared to the controls. We suggest that the sites where oral hygiene is more difficult to control have more oral hygiene education than the other sites.

The purpose of this study was to reveal analyze the relationship between status of participation in an oral health care program and oral health outcomes among patients in Korea, and to evaluate the results to provide evidence regarding the feasibility of widespread implementation of the program. Patients were designated as either cooperative or non-cooperative with the oral health care program and were assigned to each group accordingly. Modified dental hygiene process (M-DHP) of the oral healthcare program was modified to form the dental hygiene process. The study included 48 patients at a dental clinic in Busan, Korea. Questionnaires were used to collect information on oral health behavior (OHB), clinical examination was used to record bleeding on probing (BOP) and O'Leary index, and phase microscopy was used to identify microorganisms. Differences between groups were evaluated using repeated measures ANOVA. Our results showed that the group cooperative with the oral health care program showed greater improvement in OHB, BOP, and O'Leary index than the non-cooperative group. Second, patient satisfaction with the M-DHP was very high, particularly for content and the friendly nature of the staff. The cooperative group showed greater improvement in oral health than the non-cooperative group for all metrics. Our results suggest that this low-coste program, if implemented, would be actively accepted and utilized in dental clinics.

OBJECTIVES: This study aimed to evaluate the effect of oral health education interval and toothbrushing instruction, the difference between the demonstration-only method and the demonstration with chairside practice toothbrushing instruction method, and the effect of initial patient plaque control ability on the plaque index. METHODS: Patients (n=60) were randomly assigned to receive a 1-week, 2-week, or 3-week interval of oral health education and toothbrushing instruction. Each group was further subdivided into the demonstration-only group and the demonstration with chairside practice group. Patients were categorized as having "good", "fair", or "poor" initial plaque control ability, based on the Turesky modification of the Quigley-Hein plaque index (TQHI). Patients attended five sessions during which they received oral health education and toothbrushing instruction of the modified Bass technique. Plaque evaluation was performed at each visit using the TQHI. RESULTS: The plaque index tended to improve from the first visit to the fifth visit, but there were no significant differences between the 1-week, 2-week, and 3-week education interval. The demonstration with the chairside practice group showed significantly greater improvements in the plaque index, compared to the demonstration-only group. In the good, fair, and poor plaque control ability groups, the plaque index improved gradually from the first to the fifth visit. When plaque control was poor, the improvement in the plaque index increased to a greater degree after oral health education and toothbrushing instruction. CONCLUSIONS: The results of this study may be helpful for suggesting appropriate individualized oral hygiene management methods to improve plaque control ability.

OBJECTIVETo evaluate the effect of an oral health education programme for Chinese middle school student in the rural area to improve oral health knowledge.

METHODSThe students of two middle schools in the rural area of Deyang city, Sichuan province, were randomly choosed and divided into experiment group and control group, each group 200 students. The students of experiment group were taken oral health education based on school and brushed the teeth with fluoride toothpaste under the supervision of parents. No intervention study was given to the students of control group. Before the experiment and after 1 year, the caries and oral hygiene status were examined, and the oral health knowledge, attitude and behavior were investigated by questionnaire.

RESULTSThere were no significant changes of DMFT and DMFS of experiment group after 1 year (P > 0.05), while the DMFT and DMFS of control group increased obviously (P < 0.05). The oral hygiene index-simplified (OHI-S) of experiment group decreased (P < 0.05), while that of control group increased (P < 0.05). The knowledge and the attitude towards "using fluoride toothpaste was a good way for preventing tooth decay" and "eating and drinking sweet things can cause tooth decay", and the behavior of "brush the teeth 2 or more times a day", "use the toothpaste containing fluoride", "visit to dentist at least once a year" in experimental group were improved compared with control group (P < 0.05).

CONCLUSIONOral health education based on school combined the use of affordable fluoride toothpaste can improve the oral health of middle school student in the rural area.

OBJECTIVETo investigate the oral health status of undergraduate university students and to guide their oral hygiene behaviors.

METHODS3516 college students in Northwest University for Nationalities were investigated in this study according to the criterion issued by World Health Organization (WHO) on the basic methods of oral health investigation in 1997.

RESULTSThe caries prevalence rate among the students investigated was 47.87%. The average decayed teeth were 1.29. The obturation rate of caries was 20.42%. The students came from city showed significant higher caries rate than those from countryside, and so did the female students compared with the male students. Dental calculus rate was 79.78%. The dental segments related were 3.75. The worst situation was among male students and students from countryside. The examined rates were 53.30% of crowded incisor, 42.58% of maximum upper-incisor anomaly, 50.60% of the maximum lower-incisor anomaly and 31.09% of molar malposition, respectively. More rates of dentofacial anomalies showed no differences of significance between different area and gender.

CONCLUSIONIn general, the oral health status of the college students are not ideal. It is necessary to advocate early examination, early prevention and early treatment among the students in university.

This study was conducted to investigate the optimal management interval in 33 healthy adults by observing changes in oral health on the basis of the plaque control index and gingival index. When plaque control score was compared according to the period, it was found that oral hygiene management was the best in the fourth visit (p<0.05). Improved oral hygiene status was observed during the 3- and 6-month follow-up (p<0.05). Regarding gingival index, the fourth visit showed the healthiest gingival status (p<0.05). At the 3-month follow-up, the gingival index worsened, but a healthy gingival status was attained by 6-month follow-up (p<0.05). The plaque control score according to interest in dental health showed that the ‘interested’ group had good oral hygiene management (p<0.05). As a motivation for oral hygiene status and gingival health, examination with a ‘phase contrast microscope’ in the first visit and calculation of the ‘evaluation index’ in the follow-up visit tended to improve the patients' ability for oral hygiene management (p>0.05). The questionnaire survey showed, that the optimal management interval was 1, 3, and 6 months. As a result, with the effective management interval for the preventive management program focused on professional mechanical tooth cleaning, which was administered weekly, the maximum ability for oral hygiene management was attained at the fourth visit. The effective management period was 1 month. The use of a phase contrast microscope and the calculation of the evaluation index for oral hygiene management could influence the motivation to improve oral hygiene management.

OBJECTIVE: To investigate the caries status of the first permanent molars in urban and rural children aged 10-
12 in Chongqing and analyze the related factors in order to provide a theoretical basis for the prevention and treatment of children's caries and targeted suggestions for oral health education. METHODS: A multi-stage, stratified, cluster, and random sampling method was used to extract 5 057 children from 18 schools in three districts and three counties in Chongqing for oral health examination and questionnaire survey from March to May 2018. RESULTS: The total caries rate of the first permanent molar was 39.2%. The decayed-missing-filled tooth was 0.84±1.20. The rate of filling teeth was 3.4%. The rate of pit and fissure sealing was 6.1%. The prevalence of the first permanent molars was significantly different between men and women, between urban and rural areas, between only children and non-only children, and between ethnic minorities and Han nationality (P<0.001). The gap between the pit and fissure sealing was significantly different between urban and rural areas (P<
0.001). Multiple logistic regression analysis showed that many independent factors influence the occurrence of caries, including the frequency of brushing teeth every day, the frequency of eating desserts, the habit of eating dessert/drinking milk before going to bed, whether only-children or not, and parents' education background, among others. CONCLUSIONS The first permanent molars of children aged 10-12 in Chongqing have a high rate of caries but low rates of pit and fissure sealing and dental caries filling. The difference between urban and rural areas is large, children's oral health knowledge is scarce, and children have bad oral hygiene behaviors and eating habits. Children's oral health education must be strengthened, oral health preaching must be implemented in schools, the oral health knowledge of children in school must be improved, and urban-rural differences must be minimized.
