Restoration is a treatment to restore the structure of missing dental hard tissue due to caries. Flowable composite has good adaptability to the cavity wall so that it is widely used as an intermediate layer. Composite resins require an adhesive system to bond chemically with dental hard tissue. Self - adhering flowable composite combining etching, priming, and adhesive in one flowable package. This study was conducted with the aim to determine the difference in shear bond strength between Self – adhering flowable composite and flowable composite with self – etch adhesive system on dentine. The number of samples used was 38 pieces. After dentin was prepared and fixed, samples was divided into 2 groups, each group consisting of 19 samples. First group was applied with self – adhering flowable composite, second group was applied with flowable composite with self – etch adhesive system. Samples was immersed in pH 6.8 normal saline and stored for 24 hours, then dried and shear bond strength was tested using a universal testing machine. The data obtained were analyzed using independent t – test. The statistical analysis using independent t – test showed that there were significant differences in the shear bond strength between the two groups, p=0,000 (p<0.05). The study concluded that there is difference of shear bond strength between self – adhering flowable composite and flowable composite with self – etch adhesive system on dentine.

Tooth discoloration is defined as extrinsic or intrinsic staining based on localization and etiology, appearance, severity and adhesion to the tooth structure. Tooth discoloration is a cosmetic problem and the teeth whitening procedure is more conservative than the restorative method. Tooth discoloration, especially those treated endodontically is a matter of concern for patients and dentists. Among the various bleaching techniques, the technique of "walking bleach" with hydrogen peroxide stands out because of its superior aesthetic results with less side effects. This paper presents a case of tooth discoloration in non-vital teeth that was successfully bleached using the walking bleach method.

Background: Apple cider vinegar potentially can be used as an alternative to irrigation solutions because of its antibacterial compounds that can inhibit Enterococcus faecalis, a pioneer bacteria that cause root canal treatment failure. One of the ideal irrigation solution requirements is that it isn’t toxic to oral cavity tissues, so it’s necessary to run a cytotoxicity test on apple vinegar solution. Cytotoxicity test is the initial part of the evaluation of a dental material before it can be used by humans. Cytotoxicity test was performed on fibroblast cells because the irrigation solution can contact with fibroblast, which are the main cells in the periodontal ligament around the apical. The purpose of this study was to analyze the in vitro cytotoxicity effect of ACV on fibroblast cells.Method: Apple vinegar with concentrations of 0.31%, 0.63%, 1.25%, 2.5%, and 5% was tested using the MTS assay method.Result: The results showed that there was a cytotoxicity effect of apple vinegar solution as a root canal irrigation agent against fibroblasts cell. Apple cider vinegar with concentrations of 1.25%, 2.5%, and 5% are potentially toxic because the percentage of cell viability is less than 70%.Conclusion: There is a cytotoxicity effect of apple cider vinegar solution as a root canal irrigant on fibroblast cells

Background: The cause of cavities is initially due to roughness on the tooth surface, requiring fluoride varnish to prevent caries, as the varnish applies a fluoride compound to the tooth surface. Fluoride varnish reacts with the tooth enamel surface to form calcium fluoride and fluorapatite, thus making the enamel surface more resistant to demineralization and damage. Purpose: This study aims to compare the roughness of tooth enamel surfaces among three fluoride varnishes under acidic conditions. Methods: The research method uses three fluoride varnish materials: sodium fluoride 5% + tricalcium phosphate, calcium fluoride, and sodium fluoride 5% + casein phosphopeptide-amorphous calcium phosphate 2%. Samples of 81 teeth were divided into three groups (Group 1 without fluoride varnish application, Group 2 application of fluoride varnish with pH 3, and Group 3 application of fluoride varnish with pH 5). The teeth were tested before and after application of the varnishes using the scanning electron microscope and surface roughness tests. Results: The results showed a significant difference in the mean surface roughness of the enamel of the anterior deciduous teeth tested with fluoride varnish. The before and after comparisons in the pH 3 and pH 5 groups were very significant (p-value 0.000). The comparison results in each pH group after fluoride varnish administration showed no significant difference (pH 3 p-value 0.074 and pH 5 p-value 0.196). The tooth surfaces appear to be rougher after administration of an all-acid solution. Conclusion: There is a difference in surface roughness of primary teeth after being given fluoride varnish in low pH 3 immersion for 24 hours.
