Potential Side Effects of Whitening Toothpaste on Enamel Roughness and Micro Hardness
Anton Rahardjo,Eva Gracia,Grace Riska,Melissa Adiatman,Diah Ayu Maharani 대한예방치과학회 2015 International Journal of Clinical Preventive Denti Vol.11 No.4
Objective: Whitening toothpaste are easily obtained over the counter by consumers. The aim of this study was to assess the side effects of whitening toothpaste on enamel roughness and micro hardness which might contribute to increase caries risk. Methods: Enamel specimens were obtained from 60 unidentified freshly extracted human premolars. The enamel specimens were randomly divided into three groups; whitening toothpaste containing perlite, whitening toothpaste containing e-phtalimido peroxycaproid acid (EURECOⓇ HC, Indonesia), and non-whitening toothpaste as control. Tooth brushing was performed equal to 1 and 3 months. Surface roughness tester was used to determine enamel roughness and Knoop Micro hardness tester was used to determine enamel micro hardness. Results: There were statistically significant differences in enamel roughness after 1 and 3 months equivalent tooth brushing between three groups. There were significant differences in enamel micro hardness values for all groups after three months-brushing which showed a decrease in micro hardness for whitening groups and an increase in micro hardness for non-whitening group. Conclusion: Tooth brushing with whitening toothpaste for a prolonged time increases enamel roughness and decreases enamel micro hardness, which in turn increases the potential of caries risk.

A Review of Indonesia’s Dental Health - Past, Present and Future
Anton Rahardjo,Diah Ayu Maharani 대한예방치과학회 2014 International Journal of Clinical Preventive Denti Vol.10 No.3
Access to dental health care markedly improves citizens’ dental health status, which in turn improves the national quality oflife. This paper aims to review the literatures of the Indonesian Dental Health. All of the related factors that influence dentalhealth were described from 1995 to 2013. Economic and geographic barriers to access dental care still exist in Indonesia. Periodic evaluation on government policy is essential to develop an adequate dental health care system, which then couldimprove outcomes of the national dental health status.

Objective: The aim of this study was to assess the clinical efficacy of new mouthwash based on kapulaga fruit (Amomum cardamommum L.) containing 0.5% essential oil and compared to 0.5% Listerineⓡ as a positive control and placebo in reducing volatile sulphur compounds (VSCs) concentration of halitosis subjects. Methods: A randomized, double blinded, cross-over design was conducted among 20 healthy volunteers in Medan, Indonesia. Subjects were divided into 3 groups (Cardamom, Listerineⓡ, placebo group) and instructed to rinse 10 ml of experiment and control mouthwash twice per day for 5 days. After one week washout periods, each group used the opposite mouthwash. The concentration of VSCs, hydrogen sulfide, methyl mercaptan, and dimethyl sulfide were assessed twice daily for 5 days (morning at 5 a.m. and afternoon at 11 a.m.) by using oral chroma and organoleptic measurement. The three mouthwash were analyzed statistically by repeated measures ANOVA. Results: Either Cardamom or Listerineⓡ was effective in reducing VSCs for up to 4 to 5 hours after mouth rinsing, while placebo not. An analysis showed significant differences of cardamom essential oil in mouthwash and positive control group (p<0.05) from 1st and 5th day while no significant difference in placebo group (p>0.05). Results showed that Cardamom more effective than the other two mouthwashes. Unlike other mouthwash in general, the advantage of cardamom essential oil in mouthwash is alcohol-free, that could avoid from oral pain and sensitivity. Conclusion: It can be concluded that 0.5% cardamom containing essential oil in mouthwash is useful to overcome halitosis.

Objective: The use of mouthwash may increase the activity of lactoperoxidase system in saliva and may reduce the risk of halitosis. The research was conducted to determine the effect of mouthwash containing Curcuma xanthorrhiza on lactoperoxidase system activity in relation to halitosis risk. Methods: The research design was a before after clinical trial, the 5 ml saliva samples were taken from 10 subjects age 20-23 years oldat 22.00 WIB at night and at 04.00 WIB in the morning. Lactoperoxidase enzyme activity was measured using the method of Chance and Maehly while the concentration of thiocyanate ion was measured using Thomas and Aune method. Results: The mean±SD of the baseline lactoperoxidase activity absorbance in the evening 0.2463333±0.126053 and then decreased in the morning to 0.1994999±0.059258 and the mean±SD baseline thiocyanate ion from 1.9328±0.187181 in the night decreased in the morning to 1.819±0.510573. After intervention with mouthwash containing Curcuma xanthorrhiza, theincreasing of average value of baseline Lactoperoxidase activity absorbances was indicated from 0.2121±0.107991 in the evening becomes 0.240233±0.091862 in the morning, while the average of thiocyanate ion from 1.0531±0.108838 in the evening becomes 1.090267±0.285835 in the morning. There were no significant differences between the activity of lactoperoxidaseenzyme and thiocyanate ion concentrations in both treatments (p>0.05). Conclusion: The use of mouthwash containing Curcuma xanthorrhiza has the potential to raise the lactoperoxidase system activity.
