NaOCl at a concentration of 5.25% to 6% can eliminate E. faecalis, but this concentration can increase the risk of toxic effects. Cyanobacteria spirulina is known to produce several secondary metabolites that have antimicrobial activity against gram-positive and gram-negative bacteria. The aim of this study was to determine the antibiofilm power of Cyanobacteria spirulina against the biofilms of Enterococcus faecalis at concentrations of 60 mg/ml, 70 mg/ml, 80 mg/ml, and 90 mg/ml. This research was a true experiment with a post-test only group design. The object of the research was divided into 6 groups. Group 1 was a negative control group, group 2 was a positive control group with 5% NaOCl, group 3, 4, 5, 6 were treatment groups given Cyanobacteria spirulina solution at a concentration of 60 mg/ml, 70 mg/ml, 80 mg/ml, and 90 mg/ml, respectively.

Factors that cause failure of endodontic therapy include incomplete cleaning and shaping of root canals and unhermetic obturation. Endodontic failure can lead to periapical lesions. Apicoectomy is one of endodontic surgery treatment choice to preserving the tooth with endodontic treatment failure. Aim. The aim of this report was to show that in cases of failure of root canal treatment could be treat without extraction, however there was an alternative treatments such as apicoectomy that could be used to preserve the tooth and its function in the oral cavity.Case. A male 32 years old patient came to dentist with persistent pain on upper left first premolar. The tooth had been endodontically treated for ten years. Clinical examination tooth #24 had porcelain fused to metal on it, percussion test (+), bite test (+), pain on palpation. Radiographic examination showed that tooth #24 had fabricated post without gutta percha obturation on apical third. There was 3 mm round pe...

Soft glass fiber post adalah jenis pasak lunak yang besifat fleksibel, belum terpolimerisasi sehingga dapat beradaptasi untuk membentuk saluran akar sebelum proses light curin. Soft glass fiber terdiri dari sistem monomer cross-linking Bis-GMA yang dapat meningkatkan penyusutan volumetrik. Glass fiber post merupakan pasak endodontik terbuat dari glass FRC, sifat biomekaniknya baik Tujuan: Penelitian ini bertujuan untuk mengetahui apakah terdapat perbedaan kebocoran mikro soft glass fiber post dan glass fiber post sebagai pasak saluran akar. Bahan dan Metode: Penelitian ini menggunakan rancangan penelitian Post Test Only Control Group Design dengan sampel 20 gigi insisif sentral permanen rahang atas yang sudah dilakukan perawatan saluran akar.

Beta-TCP can be obtained from the hydrothermal process from the Anadara-granose shell. Beta-TCP has a chemical composition that approximates the structure of bones and teeth. Objective:The microencapsulation technique aims to increase stability, reduce side effects and toxic effects of drugs, and prolong the release of ingredients. The encapsulation process is an attempt to inhibit the dissolution speed of Calcium to prevent tunnel defects. Methods: Anadara-granose shell powder was subjected to hydrothermal processing for 18 hours and sintering for 3 hours. The beta-TCP powder was dissolved with aquadest using a magnetic stirrer until it was homogeneous, Na-alginate was dissolved in aquadest until it was homogeneous with a magnetic stirrer then the two solutions were mixed and the CaCl2 solution was dropped. The sample was divided into 3 groups; Pure Beta-TCP(K-); 7 hours stirring (P1); 8 hours ...

If the sucrose consumed is in a large amount, it will decrease saliva’s pH and soon teeth destruction will happen. To avoid it, it is necessary to change sucrose consumption habit into another kind of sugar, namely sorbitol. Sorbitol is preferred to use, because it is cheaper and easier to get. Sorbitol is made from cassava, which is plentifully grown in Indonesia. Sorbitol is not good media for bacteria to grow. Because sorbitol has a diol, so it’s difficult to catalyst by glucosyltransferase enzyme, which is produced by bacteria Streptococcus mutans. The conclusion is that sorbitol is difficult to be fermented by Streptococcus mutans so it will not decrease saliva’s pH.

Discoloration can be caused by extrinsic and intrinsic factors. One of the factors that cause teeth discoloration is due to the trauma that causes the teeth to be non vital. One alternative treatment that becomes an option is internal bleaching. Case: 37-year-old female patient with # 11 and # 21 non vital post-endodontic treatments and color changes to blackish color especially on cervical parts. Case Management: Gutta percha point taking 2-3 mm below orifice using peeso reamer. Application of Glass Ionomer type 3 cement over gutta percha point as base. Etching with 37% phosphoric acid for 20 second was then washed etching and dried with cotton pellet. The bleaching superoxol material (30-35% Hydrogen Peroxide) was applied to the pulp chamber and then covered with cotton and Glass Ionomer type 2 cement to prevent leakage of bleaching material. Control is done once a week until the appropriate color of the tooth is obtained. Conclusion: Treatment that can be done to restore the color of the original tooth without making an excessive reduction to the dental crown is by internal bleaching.

The microorganism that is colonized and embedded in the biofilm matrix is resistant to antimicrobials compared to planktonic cells. Root canal sterilization materials must have good biocompatibility with tissues. Nannochloropsis oculata is an algae that contains various compounds such as terpenoids, alkaloids, and flavonoids that have potential as antibacterial and antioxidant and can be used as alternative to root canal sterilization. Method: This research was true experimental laboratory research with post-test only control group design. The antibacterial potential of Nannochloropsis oculata was tested using the biofilm method, divided into 5 groups. The control group was: K- (aquadest), K+ (calcium hydroxide), and the treatment group was given Nannochloropsis oculata: P1 (0.625%), P2 (1.25%), and P3 (2.5 %).

Internal resorption is an unusual condition where the dentin and pulpal walls begin to resorb centrally within the root canal. If the condition is discovered before perforation of the crown or root has occurred, root canal therapy may be carried out with the expectation of a fairly high success rate. ProRoot® MTA (Mineral Trioxide Aggregate) is used for creating an apical plug during apexification, repairing root perforations during root canal therapy and treating internal root resorption and can be used as both a root-end filling material and pulp-capping material. Case. A female patient, 15 years old with pulp necrosis in right upper first incisive with heavy discoloration at the tooth came to get orthodontic treatment. At radiographic view, there is radiolucency in the root canal. Case Management. Patient was treated with root canal therapy using MTA to fill the internal resorption in root canal. After one year examination, patient can be treated with orthodontics tre...
