Background: A diastema is the distance or space between two or more adjacent teeth. This abnormality can interfere with the aesthetics of a patient, and 97% of diastemas occur in the maxilla. Various treatments can be performed for diastema closure in patients, one of which is composite resin restoration. Purpose: To explain the aesthetic procedure for diastema closure. Case: A 20-year-old female patient presented with complaints of the distance between her anterior teeth (Class I Angle occlusion with normal overjet and overbite). The labial frenum associated with the diastema was normal in size and position. The patient was not amenable to invasive procedures. Case Management: Management of midline diastema closure using the direct composite technique with DSD, the putty index method and button shade technique. Conclusion: The closure of a midline diastema with direct composite using DSD, the putty index method and button shade technique provides aesthetic results with less cost and time due to the absence of laboratory procedures.
Background: One type of composite resin material on the market is flowable composites (FC) which has low viscosity, can be applied to areas with low stress or require good penetration such as pit and fissure sealants, restoration of class II, class III, and class V. Along with technology development, self-adhering flowable composite (SAFC) material has been developed which shorten the applications time because it combines etch, priming, and bonding in one system. The incomplete composite polymerization process can release residual monomers which affect pulp and gingiva The effects of composite materials can be seen from the viability of BHK-21 fibroblast cells after being exposed by these materials. Aims: Determine the viability of BHK-21 cells after being exposed to conventional flowable composite (CFC) and SAFC. Method: The research was in-vitro experimental laboratory with post-test only control group design. BHK-21 cell cultures were included in a 96-well microplate and divided into control group (N=16) and two treated groups (N=16). The treated group was given CFC and SAFC in a disk form with 5mm in diameter and 2,5mm in thickness, then incubated for 24 hours. MTT was given, the optical density value was read by ELISA reader and cell viability was calculated. Optical density data were analyzed using Tukey HSD to compare between groups. Results: The BHK-21 cells viabitlity of SAFC group is greater than the CFC, , indicated by the optical density SAFC (value=0.1233) and CFC (value=0.0936). Conclusion: The viability of BHK-21 cells exposed to SAFC is higher than that of CFC.
Background: The existence of the smear layer, which can be produced during root canal instrumentation, may compromise the bond between filling material and the root canal walls. Therefore, the use of an effective root canal irrigation solution, a commonly employed form of which is sodium hypochloride (NaOCl), is important. Sodium hypochloride has several positive properties including effectiveness as a disinfectant agent and its ability to promote tissue-dissolution, although it is ineffective at cleaning the smear layer. There have been numerous recent studies of the application of phytomedicines in endodontics due to their advantages such as minimum toxicity and cost effectiveness. The saponin contained in both the propolis and cocoa pod husk acts as a surfactant that may lower surface tension and dissolve debris containing organic and anorganic materials. Purpose: The study aimed to provide evidence of the differences between root canal wall cleanliness when treated with 8% propolis extract and different concentrations of cocoa pod husk extract. Methods: 25 extracted teeth with single straight root canals were randomly divided into five categories (n=5). Sample preparation was performed using a rotary file and irrigated with different solutions. The first group was administered 2.5% NaOCl, the second group 8% propolis, the third group 3.12% cocoa pod husk extract, the fourth group 6.25% cocoa pod husk extract, and the fifth group 12.50% cocoa pod husk extract. The samples were then dissected into two sections at the apical third and their cleanliness scores subjected to a Mann-Whitney test with a significance level of p=0.05. Results: A significant difference was identified between all groups (p<0.05) and on the median control test, the highest value of 1.6 was recorded by the 6.25% cocoa pod husk extract, compared to the other four groups Conclusion: Cocoa pod husk extract demonstrates greater efficacy at cleaning root canal walls compared to 8% propolis extract.
