Dental plaque is a colorless thin layer, is not easily visible on the tooth surface and it causes caries. Disclosing solution is the material that can help us to see dental plaque. Chemical disclosing solution, which now exists, has several disadvantages so we need to develop natural disclosing solution. One of the ingredients in natural disclosing solution that has been studied for its effect is betacyanin, which is contained in super-red dragon fruit (Hylocereus costaricensis). This study aim to observe the coloring effect of super-red dragon fruit juice. The experimental was conducted by measuring plaque index of 20 people, who were not to clean their teeth for 24 hours (two periods), and were eaten the same foods in each period. Examination of plaque index at the end of the first period used chemical disclosing solution contains of erythrosine (FDC Red #3) and the second period used super-red dragon fruit juice. The datas were analyzed by Paired T-test. The results of the plaque index score at the first (2.47815 ± 0.811497), the second (2.7731 ± 1.0512) and did not find a significant difference (p > 0.05). The ability of super-red dragon fruit to coloring dental plaque has no difference with chemical disclosing solution, so it can be used as a natural disclosing solution.

Back ground: Dental caries and periodontal disease were the most common andwidely spread diseases affecting children. The nutrition may be one of the factorsaffecting the severity of the oral diseases. The Aims of this study was theassessment of the following oral diseases (dental caries, gingivitis) in addition toassessment of oral hygiene among 4-5 years old children in Karbala city –Iraq.Furthermore, nutritional status was assessed in relation to oral diseases.Materials and methods: A sample of 658 children (350 males, 308 females) agedfour and five years old was selected randomly from the fourteenth kindergartensin Karbala city. Diagnosis and recording of dental caries was followed the criteriaof WHO 1987. Dental plaque was assessed using plaque index of Silness and Loe,1964. Gingival health condition was assessed using gingival index of Loe andSilness, 1963. The assessment of nutritional status was performed usinganthropometric measurement (height and weight) according to Body mass indexindicator with -2SD cutoff point.Results: Caries prevalence was found to be (83%) of the total sample the mean rankvalue of dmfs was higher among boys in comparison to girls with statistically nosignificant difference (P>0.05). The value of dmfs increased with age withstatistically highly significant difference (p<0.01).The mean rank values of dentalplaque and gingival indices for total boys were found to be higher than total girlswith statistically highly significant differences (P<0.01). Recording of this studydemonstrated that 100% of children had dental plaque and gingival inflammation.Positive highly significant correlations were recorded between dental caries withdental plaque and gingival indices. The prevalence of malnutrition described byBody mass index indicator was (3.2%). According to nutritional status indicatorBody mass index-for-age, it was found that the wasted children had higher valueof dmfs than well nourished children with statistically no significant differences(P>0.05). The plaque and gingival indices were higher among well nourishedchildren than among wasted children with statistically highly significantdifferences (P<0.01).The correlation coefficient between body mass index withdental caries, plaque index and gingival index were very weak and statistically notsignificant (p>0.05).Conclusions: High prevalence of dental caries and gingivitis was recorded indicatingthe need of public and preventive programs among kindergarten children.

Dental Plaque Index

Background: Dental plaque is a soft, structured, calcified layer of bacteria that accumulates and attaches to the surface of the tooth. Efforts are made to eliminate and prevent plaque on the surface of the tooth by plaque control. Plaque control can be done mechanically, chemically, or a combination of both. Chemical control is done by using toothpaste. Catechin gambier toothpaste are polyphenolic compounds that have antibacterial activity which can prevent adhesion, inhibit the enzyme activity of glucosyltransferase and kills plaque forming bacteria. Objective: To determine the effect of catechin gambier on decreasing dental plaque index. Methods: This study is a true experimental study with pre-test and post-test control group design, conducted in March – April 2019. The subjects of this study were 44 students of Faculty of Dentistry, Andalas University. The subjects were divided into two groups, one group used catechin gambier toothpaste and an control group used placebo. Plaque index was calculated using an Turesky-Gilmore-Glickman of Quingley-Hein. Data was analyzed by t-test. Results: Average of dental plaque index in treatment group was higher than placebo group. Independent t-test showed that there was significant difference of dental plaque index beetwen two groups (p<0,001). Conclusion: Catechin gambier toothpaste can reduce dental plaque index.

Dental plaque is the primary etiologic in the development of caries and periodontal disease. Chlorhexidine gluconate 0.2% is the mouthwash that is widely used and effective in reducing dental plaque index, but this mouthwash is chemical with few side effects if used for long periods. Propolis is a bee product that has a high content of flavonoids antibacterial and has many benefits in health and has minimal side effects because it belongs to natural product. This study aims to determine differences in the gargling effectiveness using Chlorhexidine gluconate 0.2% and bee propolis solution 12.38% (Apis mellifera) in reducing dental plaque index. The method used in this research was a clinical experimental with the design of one group pretest and posttest. The subjects consisted of 20 students of MA DR. Abd. Ahmad PGAI Padang. Dental plaque index was measured using PHP plaque index before and after gargling using the solution of bee propolis (Apis mellifera) 12.38% and chlorhexidine gluconate 0.2%. The data of research findings were analyzed using paired T-test (p<0.05). The results show that the mean of plaque index reduction of gargling using the solution of bee propolis 12.38% (Apis mellifera) is 0,88 with the standard deviation of ± 0.66 and the mean of plaque index of gargling using Chlorhexidine gluconate 0. 2% is 1.56 with the standard deviation of ± 0.79. There is a significant difference with p value = 0.005 (p <0.05). Chlorhexidine gluconate 0.2% shows higher reduction, but this mouthwash is the chemical with few side effects, while the solution of bee propolis 12.38% (Apis mellifera) is a natural substance that is safer to use.
