<![CDATA[Bleaching is the tooth whitening by applying chemical materials oxidizing the organic tooth pigmentation and creating smaller and lighter molecules. Commonly used in the tooth bleaching is hydrogen peroxide. Strawberry and apple contain hydrogen peroxide and ellagic acid which will bond with an unsaturated bond of the tooth pigmentation. The purpose of this research was to finding out and measuring the tooth whitening level and effectivity between the strawberry and apple juice. The type of this research was a true experimental (in-vitro), using 30 samples of maxillary premolars with cutted radicular until the CEJ. Samples were divided into 3 groups (immersed in strawberry juice; apple juice; and mineral water); with three times daily immersion in one week. The tooth colour level was measured using a spectrophotometer. Data were analyzed using the one-way ANOVA and LSD test. The results showed significant differences among all groups. Normality test showed the variance between homogenous groups, with the p-value of 0.198 (p ⥠0.05). The one-way ANOVA test results showed a significance value (0.000), indicated a significant degree of the tooth whitening level between all groups. The LSD test results showed that the tooth whitening level in group I (immersed in strawberry juice) was significantly different to group II (immersed in apple juice) and group III (immersed in mineral water), with a significance value of 0.01 and 0.00 ( p ⤠0.05). The tooth whitening level in group II was significantly different from group III, with a significance value of 0.03 (p ⤠0.05). There were differences in the tooth whitening level between immersion in strawberry juice, apple juice, and mineral water, with the most effective tooth whitening level found in the strawberry juice immersion.]]>

<![CDATA[Introduction: One of the most frequent dental problems that confronted dentist is tooth discoloration which can cause significant cosmetic problems. Extrinsic tooth discoloration occurs when stain forms on the tooth surface or in the pellicle and the common causes of extrinsic tooth discoloration is coffee. Robusta coffee contains high level of chromogenic compound which can incorporate itself into the acquired pellicle and tannic acids that can denature the pellicle protein and increase its stain ability. The purpose of this experiment was to investigate the tooth discoloring effect of Robusta coffee solution. Methods: This research type was a true experiment (in vitro) using 30 samples of maxillary first premolar whose roots had been cut until the CEJ. Samples were divided into 2 groups (which are soaked in Robusta coffee solution and the other in mineral water) of 15, with a frequency of three times daily for seven days. The difference in tooth color changes was measured by using a spectrophotometer. Results: This research was analyzed by using t-test and there was a significant difference between the two groups (p-value≤0.00). Conclusion: Robusta coffee effected to tooth discoloration.]]>

<![CDATA[Introduction: Overhanging approximal restoration may causes gingival inflammation, periodontal tissue destruction, decreases alveolar bone height, and caries reccurence. Overhanging restoration can be detected clinically and by radiography image. Overhang restorations can occur due to the poor filling procedures, one of which is the limitation of supporting tools. Restoration of teeth done in Puskesmas often found unavailability constraints supporting tools so that in cases of approximal caries often experience overhang. The aim of this study was to evaluate the incidence of overhanging proximal restoration at Tarogong Public Health Centre in Garut Regency West Java Indonesia. Methods: This study was a descriptive cross sectional for the incidence on patient with overhanging approximal restoration who visited at Dental Unit Tarogong Public Health Center in Garut Regency. Intraoral clinical examination was conducted to examine visually and by tactile for the overhang restoration. Periapical radiography examination was taken and became supporting examination. Results: Collected data were 43 cases of overhanging approximal restoration from total 57 patients. The incidence of overhanging approximal restoration were 75,4. Conclusion: The conclusion of this study by radiography was the incidence of overhanging restoration was 75.4 which showed that overhanging restoration approksimal more than good restoration aproksimal at Tarogong Public Health Centre in Garut Regency West Java Indonesia.]]>

<![CDATA[Introduction: Calcium release from the enamel surface is known as enamel demineralisation. Enamel demineralisation is a chemical process of mineral loss from the email structure. One of the factors that cause demineralisation is the presence of acids derived from food or beverages consumed. This study was aimed to determine the effects of soft drinks and the amount of calcium release from the enamel surface. Methods: This study was an in-vitro experimental. The population was extracted maxillary premolars from orthodontics clinics in health centres, hospitals, and private clinics throughout Bandung and Jakarta. As many as 20 crown of maxillary premolars divided into two groups. Dissolved calcium was measured using the Atomic Absorption Spectrophotometry (AAS). Data obtained was tested using an independent t-test. Results: The results showed that the amount of calcium released after exposure of soft drink was higher than soda water. The average amount of calcium released after soft drink exposure was 4122 ppm and soda water was 3492 ppm. Conclusion: Soft drink affects the calcium release from the enamel surface.]]>

<![CDATA[Introduction: Tooth whitening (Bleaching) is a method to restore discoloured teeth to the original tooth colour with a chemical process. The materials used in the bleaching process are hydrogen peroxide, sodium perborates and carbamide peroxide. Pear fruit consists of hydrogen peroxide which is potentially an oxidizing compound that produces free radicals that react with unsaturated bonding teeth staining substances. This study aims to analyzed tooth whitening effect of exposure of pear juice with different frequencies. Methods: The type of research was true in vitro experiment where samples of 32 maxillary premolar teeth had cut the root to CEJ. The specimens divided into four groups. The first group was soaked in pear juice two times, the second group three times, a third group four times, and the fourth was the control group using only mineral water. Tooth colour was measure using a Spectrophometer, conducted before and after individual soaking. Results: The research result is tested with ANOVA and Newman- Keuls Range Test showed a significant difference of tooth whitening degree between the frequency exposure pear juice after 2 times soaking, 3 times soaking and 4 times soaking. Conclusion: There are difference degree of whitening from the difference frequency exposure of pear juice and Pear juice exposure of 4 times gives higher whitening effect compared to frequency of 3 times, 2 times and control group which is soaked in water.]]>
