<![CDATA[One of the objectives of successful endodontic treatment is the hermetic obturation of the root canal system. To achieve this, the root canal filling must seal the canal space both apically and coronally to prevent the ingress of microorganisms or tissue fluids into the canal space. Apical leakage is reported a common reason for the clinical failure of endodontic therapy. Leakage through an obturated root canal is expected to take place at interfaces between sealer and dentin or sealer and gutta-percha, or through voids within the sealer. Hence, the sealing quality of root canal filling depends much on the sealing ability of the sealer. Therefore, anything that may influence the adaptation of the root filling to the canal wall is can determine the degree and the extent of leakage, and ultimately the prognosis of the endodontic therapy. In endodontic therapy, the smear layer formation results from root canal preparation and may influence the effective seal of the root canal system. The smear layer formation is mainly composed of inorganic components (dentin debris) and organic materials, such as pulp tissue remnant, bacteria, and blood cells. Removal of the smear layer from the root canal walls before the obturation can reduce the leakage of root canal sealer. To remove the smear layer use 10 ml 17% EDTA followed by 10 ml of 5.25% NaOCl as irrigating solution. This paper discribe about how the effectivity of EDTA as irigating solution to remove the smear layer especially in the apical root canal with many lateral canal to reduce the apical leakage.]]>

<![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[Cleaning and shaping of the root canal as the foundation for successful endodontic therapy. Cleaning of the root canal as the removal of all the contents of the root canal systems before and during shaping. Mechanical cleaning as the most important part of the root canal therapy. Instrumentation of the apical region has long been considered to be an essential component in the cleaning and shaping process. The apical area as the critical zone for instrumentation. The apical portion of the root canal system can retain microorganisms that could potentially cause periradicular inflammation. The nickel-titanium rotary instrumentation system to facilitate the cleaning and shaping process. Larger instrumentation sizes not only allow proper irrigation but also significantly decrease remaining bacteria in the canal system. How the larger apical sizes preparation must be achieved to clinical success. This paper will describe the major factors impacting the selection of final apical size, the factors are the anatomy of the apical constriction, root canal diameter, apical instrumentation, and bacteria in dentin tubuli.]]>

<![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[Resin composites is one of the currently most frequently used aesthetic restoration material. A drawback of resin composites is contraction of polimerization which may result in the coming about of dental sensitivity due to microleakage. Flowable composite has high flow capacity and better adaptation capability making the thinnest application on cavity surfaces. An advantage of flowable composite is the possibility of using it as liner in composite resin restoration, which is expected to minimize the occurrence of post restoration dental sensitivity. This research was a descriptive research using the purposive sampling technique. The sample consisted of 27 first incisive and/or second incisive permanent maxilla teeth. A sensitivity test was used on the sample using chlor ethyl and completing questionnaire by patients. The result of dental sensitivity test indicated that 88.9% of the patients did not experience post restoration dental sensitivity and 11.1% of the patients was experience a decrease of dental sensitivity level. Based on research results the conclusion could be drawn that the used of flowable composite as a liner in resin composite class III restoration didn't had a post restoration dental sensitivity.]]>
