AIMTo find the relationship of periodontal status and dental caries status with oral health knowledge, attitude, behavior, among professional students in India.

METHODOLOGYIn a cross sectional study, a total of 825 students (males: 577, females: 248) from six professions were surveyed using a self administered structured questionnaire including 41 multiple choice questions and the WHO Oral Health Assessment Form (1997). The data was analyzed using the SPSS version 13.0 to perform the Student's t-test, ANOVA test, Scheffe's test and Chi-square test, linear regression analysis.

RESULTSThe mean percentage scores of the students for knowledge were 53.25 +/- 15.05; for attitude 74.97 +/- 20.48; and for behavior 59.09 +/- 18.77. The percentage of students with calculus score was found to be significantly high (43.8%). The percentage of professional students with DMFT >4 was 14.1% and the percentage of students with decayed teeth was 46.2%. The regression analysis showed that the oral health behavior of the students was dependent on the attitude (P < 0.001), but showed no significant linear relation with the knowledge. Also, that the mean DMFT score was dependent on the oral health behavior (P < 0.05), but showed no significant relationship with the knowledge and attitude of the students. The periodontal status was independent on the knowledge, but showed a significant relationship with attitude and behavior of the students.

CONCLUSIONA positive attitude and adherence to good oral hygiene behaviors is associated with better oral health.

BACKGROUND: This study aimed to investigate allergic rhinitis and the relationship between allergic diseases, such as asthma and allergic rhinitis, and dental caries and periodontal disease using the raw data from third year of the 6th Korean National Health and Nutrition Examination Survey.METHODS: A total of 3,729 subjects aged over 30 years who underwent examination for allergic diseases and an oral health checkup were selected. The data were analyzed using SPSS IBM SPSS ver. 25.0 (IBM Corp., USA). Composite sample cross correlation and composite sample logistic regression analyses were performed using the composite sample general linear model.RESULTS: On examining the socioeconomic characteristics of the subjects suffering from allergic disease and the relationship between allergic disease and oral health, allergic rhinitis was more frequently found in younger subjects with a higher level of education. Periodontal disease and dental caries were more frequent among female, older age groups, lower income earners, and subjects with a lower level of education (p<0.05). On examining the relationship between the oral health characteristics of the subject and allergic diseases and oral health, allergic rhinitis was more common in subjects with a good oral health status perception than those who answered “bad” to the oral health status question. The community periodontal index of treatment needs (CPITN) score was higher in subjects who answered “poor” to the oral health status question, lower frequency of brushing, and higher in subjects using secondary oral hygiene products; the decayed, missing and filled teeth (DMFT) index was higher in subjects with a perception of poor oral health status (p<0.05). The DMFT index was high in the asthma group, and the CPITN score was high in the group who answered “no” to allergic rhinitis.CONCLUSION: There is a relationship between asthma and allergic rhinitis and the DFMT index and CPITN score. Corresponding oral programs for allergic patients need to be developed.

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.

OBJECTIVETo evaluate the oral health-related quality of life (OHRQOL) in type 2 diabetic patients with chronic periodontitis.

METHODSA total of 80 type 2 diabetic patients with chronic periodontitis who had at least 16 teeth and never accept any periodontal therapy in latest one year were recruited. The clinical periodontal index such as probing depth, attachment loss (AL), modified bleeding index, plaque index were obtained with a Williams type periodontal probe. All accepted structured questionnaire interview including the evaluation of OHRQOL.

RESULTSThe geriatric oral health assessment index (GOHAI) results demonstrated good content validity, construct validity and responsibility. The periodontal index had positive correlation with the GOHAI scores. Individuals with self-unsatisfied of oral health status, using hypoglycemic drugs, accompanied with serious gingival inflammation and higher AL had relatively poor OHRQOL.

CONCLUSIONThe OHRQOL of type 2 diabetes with chronic periodontitis and the negative experiences of items listed in GOHAI questionnaire were affected by self-conscious of oral health and periodontal inflammation status.

The aim of this study was to evaluate the effect of mouthrinse products containing deep sea water. We used original deep sea water (DSW) and processed deep sea water desalinated by reverse osmosis at one time (DDW-1), by reverse osmosis at two times (DDW-2) and concentrated by reverse osmosis (CDW). We made 2 kinds of mouthrinse products containing CDW and other agents for smell and taste and one product without deep sea water. The negative control was distilled water. In vivo study, the dental plaque index scores and the gingival index scores were reduced after 4 weeks mouthrinsing three times daily with 4 kinds of deep sea water and 3 kinds of mouthrinse products(p<0.05). The pH of dental plaque in 1 minute after mouthrinsing was not higher than 5.5 in all solutions, but the pH in 20 minutes after mouthrinsing was higher than 5.7 in DSW, CDW and 3 kinds of products which had higher mineral contents. In vitro study, the mouthrinse solutions containing the higher mineral contents were also the more effective in reduction of methyl mercaptan which is one of the causes of halitosis. The 2 kinds of products containing deep sea water killed Streptococcus mutans (ATCC 25175) in culture plates in one minute. These results indicate the usability of deep sea water in mouthrinses for oral hygiene management.

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 Löe and Silness gingival index (GI), Silness and Löe 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±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.

OBJECTIVES: The influence of sex steroid hormones on periodontium can be knockdown with good plaque control. The aim of the present study was to evaluate periodontal status in pre- and postmenopausal women with periodontitis following non-surgical therapy. METHODS: Total 60 female patients' periodontal status was measured by periodontal index (PRI), and oral hygiene status was measured by plaque index (PI). Both the parameters were measured at baseline i.e. before scaling and root planing and after 3 months intervals post treatment. Data were analyzed using SPSS version 21. RESULTS: The mean PRI scores in premenopausal group were 5.68 ± 0.64 and 2.53 ± 0.13, and PI scores were 1.84 ± 0.17 and 0.91 ± 0.13 respectively at baseline and 3 months. The mean PRI scores in postmenopausal group were 6.08 ± 0.46 and 2.55 ± 0.12, and PI scores were 1.86 ± 0.24 and 1.00 ± 0.24 respectively at baseline and 3 months. CONCLUSIONS: There was more desirable response to non-surgical periodontal therapy in both the groups but not significant variation in between two groups.

A novel glucanhydrolase from a mutant of Lipomyces starkeyi(KSM 22) has been shown effective in hydrolysis of mutan, reduction of mutan formation by Streptococcus mutans and removal pre-formed sucrose-dependent adherent microbial film and Lipomyces starkeyi KSM 22 dextranase has been strongly bound to hydroxyapatitie. These in vitro properties of Lipomyces starkeyi KSM 22 dextranase are desirable for its application as a dental plaque control agent. This study was performed to determine oral hygiene benefits and safety of dextranase(Lipomyces starkeyi KSM 22 dextranase)-containing mouthwash in human experimental gingivitis. This 3-week clinical trial was placebo-controlled double-blind design evaluating 1U/ml dextranase mouthwash and 0.12% chlorhexidine mouthwash. A total 39 systemically healthy subjects, who had moderate levels of plaque and gingivitis were included. At baseline, 1, 2 and 3 weeks, subjects were scored for plaque(Silness and Loe plaque index and plaque severity index), gingivitis(Loe and Silness gingival index), and at baseline and 3 weeks of experiment, subjects were scored for plaque(Turesky-Quingley-Hein's plaque index and plaque severity index), tooth stain(Area and severity index system by Lang et al). Additionally, oral mucosal examinations were performed and subjects questioned for adverse symptoms. Two weeks after pre-experiment examinations and a professional prophylaxis, the subjects provided with allocated mousewash and instructed to use 20-ml volumes for 30s twice dailywithout toothbrushing. All the groups showed significant increase in plaque accumulation since 1 week of experiment. During 3 weeks' period, the dextranase group showed the least increase in plaque accumulation of Silness and Loe plaque index, compared to the chlorhexidine and placebo groups, but chlorhexidine group showed the least increase inplaque accumulation of Turesky-Quingley-Hein's plaque index. As for gingival inflammation, all the groups showed significant increase during 3 weeks of experiment. The dextranase group also showed the least increase in gingival index score, compared to the chlorhexidine as well as the placebo groups. Whereas the tooth stain was increased significantly in the chlorhexidine group, compared to the baseline score and the placebo group since 3 weeks of mouthrinsing. It was significantly increased after 3 weeks in the dextranase group, still less severe than the chlorhexidine group. As for the oral side effect, the dextranase group showed less tongue accumulation, bad taste, compared to the chlorhexidine group. From these results, mouthrinsing with Lipomyces starkeyi KSM 22 dextranase was comparable to 0.12% chlorhexidine mouthwashin inhibition of plaque accumulation and gingival inflammation and local side effects were if anything less frequent and less intense than chlorhexidine, in human experimental gingivitis. All data had provided positive evidence for Lipomyces starkeyi KSM 22 dextranase as an antiplaque agent and suggested that further development of dextranase formulations for plaque control are warranted.
