Abstract

Abstract   Radiotherapy of head and neck area may damage cancer cell, but it has side effect to damage healthy tissue, including salivary gland, thus it may cause the decreasing of salivary volume. Saliva is a complex fluid, consisting of secretion and gingival sulcus fluid, saliva is produced by major and minor salivary gland. Normal mean value of unstimulated salivary volume in healthy individual in a minute ranges between 0,25 - 0,35 ml. Due to radiotherapy of head and neck area occurs damage of ray cell mainly in parotid gland witch more radiosensitive characteristic to radiation, if inflammation becomes chronic will occur fibrosis in salivary gland that can cause the decreasing of salivary volume. This study aimed to measure salivary volume and to know the relation of salivary volume based on radiotherapy intensity in radiotherapy receiver of head and neck area at Central H. Adam Malik Hospital Medan. The study design used was Observational Analysis with Cross Sectional approach. This study was carried out in April – June 2012. Sample method selection was purposive sampling method. Salivary collection was done by spitting method and the mean value was measured then data analyzed with Anova test by using SPSS 17 program. The result of study in radiotherapy receiver of head and neck area at Central H. Adam Malik Hospital Medan was the mean value of highest salivary volume was on the group of 1 - 5 x radiotherapy intensity with mean±sd = 0.15060 ± 0.067818 ml/minute and was decreasing simultaneously until the lowest salivary volume on the group of 31 - 35 x radiotherapy intensity with mean±sd = 0.00840 ± 0.0066731 ml/minute.The result of study showed the decreasing of salivary volume due to side effect of head and neck radiotherapy .

Abstract

Abstract Citrus fruits are produced in many countries around the world. Some of the researches showed that citrus fruits contain significant antimicrobial activity towards bacteria in mouth so it could reduce the plaque formation because its polyphenol compound like tannin and naringin. Tannin can inhibit bacteria growth with the strong binding iron capacity and also inhibit the adhesive of Streptococcus to the enamel surface. Naringin is effective in inhibit the growth of Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis significantly. The aim of the study is to analyze the effectiveness of citrus fruits in reducing the plaque formation. This is an experimental study with time series design. Total samples of 35 students of Faculty of Dentistry University of North Sumatera were selected with systematic random sampling. They were being control for the first 10 days as control group and the same sample were continue to be treated as treatment group for 10 days. When they were in treatment group, all of the samples were instructed to consume the citrus fruit once a day. Loe&Silness plaque index is used to measure the plaque index score. The result of this research showed that increase of the plaque index in treatment group is lower than control group. It means siem madu citrus fruit is effective in reducing the plaque formation. The citrus fruit might reduce the plaque formation because the mechanical effect of its fiber in removing plaque and also the chemical effect of its substrates.   Key words: siem madu, citrus fruit, plaque formation

Abstract

Abstract There have been studies in the last decade reported the relationship between periodontal disease and coronary heart disease (CHD). Results showed that periodontitis causes systemic inflammation which increase the risk of CHD. The findings also support that an individual with periodontal infection has a greater risk to suffer CHD than an individual without it. The aim of this study is to find the difference between periodontal index on CHD patient compared to non-CHD patient in RSUP H. Adam Malik Medan. This study was done by using the observational method and cross-sectional approach. The samples consisted of 42 CHD patients from Cardiology Polyclinic and 40 non-CHD patients from Dental Polyclinic at the RSUP H. Adam Malik Medan. They were selected with the purposive sampling method. Each subject was interviewed and underwent a clinical periodontal examination on periodontal index. The secondary data was collected from the medical record. The results showed that the mean value of the periodontal index on CHD group (5,640) was higher than of  non-CHD group (1,023). In conclusion, there was a significant difference in periodontal index (p < 0,05) between CHD patients and non-CHD patients, by which CHD patients are inclined to suffer periodontal disease more than non-CHD patients Key words: periodontal disease, coronary heart disease, periodontal index

Abstract

Abstract Smoking is a habit that is often encountered in the community and may locally cause disturbances in the oral cavity such as leukoplakia, stomatitis nicotina, smoker´s melanosis, coated tongue, hairy tongue, candidiasis, leukodema, tobacco keratosis, gingivitis, periodontitis, acute ulcerative necrotizing gingivitis and oral cancer. There is a research that reports that coated tongue is the most frequently encountered lesion in smokers which makes up 64%. The purpose of this research was to examine the relationship between cigarette smoking which consists of the type of cigarette smoked, duration of smoking and number of cigarettes smoked per day with the occurrence of coated tongue. This research is an analytic survey which was conducted using a cross sectional approach to study the dynamics of correlation between risk factors and effects which are smoking and the occurrence of coated tongue. This research was conducted at the Biro Rektor of Universitas Sumatera Utara, Indonesia in Medan, during October and November 2012. The number of samples taken were 68 smokers consisting of non-academic personnel of USU. Data on demographic and smoking habit was obtained by direct interviews with subjects while clinical data was obtained by clinical examination of the subjects who met the inclusion criteria. Analysis of data was performed to test the hypothesis by collecting the univariate and bivariate data. The obtained data were analyzed with Chi-Square test statistics. The results of this research shows anrelationship between the type of cigarettes smoked (P = 0.001) and the number of cigarettes smoked per day with the occurrence of coated tongue (P = 0.010). However, there was no correlation between duration of smoking and the occurrence of coated tongue. Out of the 68 personnel that were examined, there were 55 people who have coated tongue (80.88%). In conclusion, there is a significant relationship between smoking and the occurrence of coated tongue but no significant relationship between the duration of smoking and the occurrence of coated tongue. Key Words: Relationship, Smoking, Coated Tongue

Abstract

Dental caries is a disease of the mineralized tissue of the teeth, caused by the action of microorganisms on fermentable carbohydrate. Streptococcus mutans is the bacteria which plays a vital role on the caries process. Brushing teeth twice a day with appropriate dentifrice is a rational choice for preventing caries disease. Chitosan is derived from deacetilation of chitin with concentrated NaOH solution. The aim of this study is to compare antibacterial effect between dentifrices containing horseshoe crab’s high molecular chitosan (tested material), commercial dentifrice and placebo dentifrice against bacterial growth of Streptococcus mutans cultivated on NA medium. Antibacterial materials are divided into 5 groups: group I dentifrice containing horseshoe crab’s high molecular chitosan 0,5 %; group II 1,5%; group III 2,5%; group IV commercial dentifrice  (NaMFP) as control (+) and group V placebo dentifrice as control (-). The results of the study after 24 hours showed that the largest inhibition zone was the group I 0,5 % > placebo dentifrice > group II 1,5% > Group III 2,5% > commercial dentifrice. The results of one way ANOVA showed a significant difference between the groups of dentifrice containing horseshoe crab’s chitosan 0,5%; 1,5%; 2,5%; placebo dentifrice and commercial dentifrice to inhibit the growth of Streptococcus mutans. In conclusion, dentifrice containing horseshoe crab’s high molecular chitosan can inhibit the growth of Streptococcus mutans with larger inhibition zone  compared with commercial dentifrice. Key words: caries, Streptococcus mutans, dentifrice, chitosan
