Introduction: Remineralization is the process of returning mineral ions into a hydroxyapatite structure characterized by mineral deposition on the enamel surface. The presence of mineral deposition would affect the microhardness of tooth enamel. Fluorine, as the remineralization agent is known with side effects such as fluorosis. Cocoa bean extract contains theobromine that can be used as an alternative remineralization ingredients. The objectives were to determine enamel microhardness after remineralization using cocoa bean extract as natural material and to compare with fluorine as synthetic material. Methods: Thirty-six maxillary first premolar tooth crowns was cut and planted in the epoxy resin. Teeth were then immersed in demineralization solution at pH 4 for 6 hours. The sample were divided into 2 groups, 18 for the fluorine group and the remaining group of cocoa extract. Vickers microhardness test was used before treatment, both after demineralized and remineralized. Results: The value of enamel microhardness before treatment in the fluorine group was 376.17 VHN as average value and the cocoa extract group was 357.33 VHN. After demineralization in fluorine group was 268.13 VHN and cocoa extract group was 235.93 VHN. After remineralization in fluorine group and cocoa extract group, respectively, 321.08 VHN and 293.86 VHN. The results of the analysis revealed that the level of enamel microhardness after remineralization was not significantly different in both groups (p>0.05). Conclusions: The findings indicated the ability of cocoa extract to increase the microhardness of enamel and implies the potential as a fluorine substitution for remineralization.

ABSTRACTIntroduction: Tooth discolouration post-endodontic treatment can be caused by root canal filling materials. The endodontic material left in the pulp chamber will infiltrate the dentinal tubules, thus causing staining. Intrinsic discolouration due to root canal filling is frequently seen in an endodontically-treated third cervical. Walking bleach is an internal bleaching technique used in post endodontic discolouration cases. The purpose of this case report was to describe the management of post-endodontic root canal discolouration with the walking bleach technique. Case report: A 20-year-old female patient came to Universitas Padjadjaran Dental Hospital (RSGM Unpad) with complaints that her maxillary anterior left teeth were brownish and disturbing her appearance. Clinical examination showed that tooth 21 had a mesiobuccal composite fill with intrinsic discolouration, in which the brownish colour was appearing predominantly in the cervical area. Vitality, percussion and palpation test results were negative. Radiological examination showed a radiopaque image resembling a root canal filling material from the pulp chamber to two-thirds of the root canal length. The diagnosis was previously treated tooth. Root canal re-treatment was carried out and followed by an internal bleaching procedure using the walking bleach technique. The gutta-percha was removed 3 mm below the orifice, and a glass ionomer cement barrier was made. 35% H2O2 paste was placed above the barrier and then covered with a glass ionomer spill. After one week of obtaining the appropriate colour, calcium hydroxide was applied to the pulp chamber. The tooth was restored with composite resin two weeks after. The application of 35% H2O2 paste using the walking bleach technique was proven to be able to restore the teeth colour. Conclusion: The walking bleach technique is one treatment option that can effectively treat intrinsic discolouration of non-vital teeth post-endodontic treatment.Keywords: Intrinsic discolouration, internal bleaching, walking bleach technique.

Root canal treatment in necrosis blunderbluss apices difficult to treat and to obtain a good apical seal. A therapy called apexification is required to induce the formation of a calcified apical barrier. The aim of this case report is to demonstrate apexification blunderbluss apices by the use of mineral trioxide agregat (MTA) as an apical plug and follow up fiber reinforced composite (FRC) after bleaching and direct composite. A 18 year old male patient reported with fractured right central incisor on the incisal with blunderbluss apices and the tooth has brown discoloration. MTA as an apical plug was used after the root canals had been debrided and rinsed with 2,5% NaOCl. Calcium hydroxide paste was placed in the canal before the apical portion of the canal was filled with the MTA apical plug. Bleaching before a FRC was placed in the remaining portion of the canal, core build-up was done and direct composite filled over it. At 6 month follow-up period the clinical and radiographic appearance of the teeth had healed successfully. MTA appears to be a promising alternative to calcium hydroxide apexification because of its superior sealing ability, high biocompatibility, and reduced treatment time. The reinforcement of the composite resins by fibers improves their fracture toughnes and resistance. Bleaching and direct composite to make coronal sealing and tooh color returned to the original color. MTA in apexification is valuable method if the quality of coronal sealing can be enhanced.
