Background: The use of commercial desensitization toothpaste is one of the way to treat dentine hypersensitivity. Desensitization tooth paste contains an active ingredient which is able to occlude the dentinal tubules to minimize the movement of fluid in the dentinal tubules which lead to dentin hypersensitivity. Desensitization toothpaste containing various kind of active ingredients for occluding the dentinal tubules. The purpose of this research was to determine the differences of desensitization tootpaste ability (Pepsodent Sensitive Expert® and Sensodyne Repair and Protect®)inoccluding dentinal tubules with different active ingredient (hydroxyapatite and Novamin).Method: The research is experimental laboratories with post test group design. The sample used was 8 dentin disc with 8 mm length and 3 mm width, the sample was divided into two groups thattreated with Pepsodent Sensitive Expert® desensitization toothpaste and the group treated with Sensodyne Repair and Protect® desensitization toothpaste. A non-parametric data analysis was carried out by MannWhitney(<0.05). Result:The result showed that there were no significant differences in the percentage of dentinal tubulesin both treatment groups.Conclusion:The conclusion of this research is both of Pepsodent Sensitive Expert® and Sensodyne Repair and Protect® desensitization tootpaste have the same ability in occluding the dentinal tubules.

Background: Dental plague has been known to be the major agent causing dental carries and periodontal disease which are the most common dental and soft tissue diseases with the prevalence of 70-80%. The preventive measure including the use of chemical substance of catechin having anti-plague activity in the form of mouth wash has been shown to have effects on the dental plague formation. The objective of this study was to find out the duration of mouth washing with boiled gambir (Uncaria ambir) on the plague formation in Pondok Pesantren Al-Badriyah Mranggen, Demak.Design and Method: In this study using Pretest-Posttest Control Group Design, 44 samples of subjects was divided into 4 groups of 11 each. Group I, II, II were treated with the mouth wash of Uncaria gambir boiled 2, 3, 4 minutes respectively. Group IV serving as control was treated with mouth wash of water for 3 minutes. The data was analyzed with non parametric test using Kruskal-Wallis followed by Mann-Whitney test with p < 0.05.Result: Kruskal Wallis analysis showed a significant difference in mean of plague before and after the treatment among the four groups (p < 0.05). Mann-Whitney test showed no significant difference between group I and III ( p> 0.05) and significant difference for the rest of the groups (p < 0.05). Conclusion: The mouth rinse duration using boiled Gambir has been shown to have an effect on the dental plague formation. 3 minute mouth washing shows the optimum effect (Sains Medika, 4(1):57-62).
