Background: The dimensional stability of alginate impression material is very important for obtaining an accurate cast. Seal bag storage is one way to maintain dimensional stability of the impression material. Objectives: This research aims to compare the dimensional stability of alginate impressions between imprESSIX Color Change (Alginate A), Algeniux Normal Set Major (Alginate B), and Aroma Fine Plus Normal Set (Alginate C). The alginate impressions were stored in seal bags for 0 min, 10 min, 3h, 24h, 72h, 120h, and 168h. Method: Sixty-three gypsum cast samples were obtained from a master die using 3 different alginate impression materials. The alginate impressions were stored in separate seal bags for each of the seven different time intervals, then the samples were poured with gypsum type III. The buccal cusp length from right first molar to left first molar was measured for each gypsum cast sample using calipers and compared with the master die. The data were analyzed with two-way ANOVA followed by post hoc LSD test. Results: The distance between the mesial buccal cusps of the right and left first molar was 52.280 mm for the master die. Gypsum cast samples of alginate A and B showed shorter lengths compared to master die, but the difference was not significant (p>0.05). A significant difference in dimensional stability was observed for alginate C (p<0.05) after 120h (52.080 mm) and 168h (52.057 mm). Conclusion: Dimensional stability of alginate impression was influenced by alginate composition and seal bag storage time. Seal bag storage could hold the dimensional stability of alginate A and B up to 168h, but for alginate C, the stability only lasted for 72h.

Background: Addition silicone is an elastomeric impression material used to obtain an accurate impression. Compatibility between impression material and gypsum will affect the surface quality of the resulting models. Types III and IV gypsum are very commonly used in dentistry to pour impressions and produce working models; despite this, there has been no further research regarding the differences between the two types in terms of compatibility with addition silicone impression materials. Objectives: To compare the compatibility of types III and IV gypsum with addition silicone impression materials. Methods: Gypsum compatibility was assessed on the basis of its ability to reproduce lines of certain widths. Thirty samples were produced by impressing a stainless steel ruled block (in accordance with ANSI/ADA Specification No. 19) with addition silicone (independent variable) and then pouring in type III or IV gypsum (dependent variable). The samples were divided into two groups: in Group A, addition silicone was poured with type III gypsum; in Group B, addition silicone was poured with type IV gypsum. The lines from the stainless steel ruled block that formed in the gypsum samples were observed with a microscope at 10x magnification. Each line was then assessed with a score from 1 to 4, according to Morrow’s standardization, where a score of 1 indicates that the line was reproduced clearly and sharply over its entire 25 mm length, and a score of 4 indicates that the line is reproduced incompletely with roughness and/or blemishes. The data were analyzed using the Mann–Whitney U test. Results: Group B (addition silicone poured with type IV gypsum) produced more results rated as 1 (60% of the group’s samples) than Group A (only 46.67% of the group’s samples). Conclusion: On the basis of the number of scores rated as 1, type IV gypsum was more compatible than type III gypsum with addition silicone.

Indirect resin composite veneer restoration (VIRK) is used as esthetic restoration for anterior teeth. Attachment between restoration and enamel surface was obtained using multi-step (MS) resin cement. Recently, a one step self-adhesive dual-cured resin cement (SADRC) was introduced. Determine failure analysis of VIRK bonded to enamel using MS resin cement and SADRC. Twenty specimens of buccal surface of enamel premolar were used. The specimens were flattened using silicon carbide no.2000. VIRK cylindrical specimens (diameter 3mm, thickness 3mm), were light-cured in Solidilite chamber (Shofu, Japan) for 3 minutes. VIRK specimens were then divided into: Group I with Multi-step resin cement (n=10) and Group II with SADRC (n=10). After 24h in incubator (37oC), Shear Bond Strength (SBS) were tested using Universal Testing Machine(Shimadzu AG5000). Failure analysis was determine using Stereomicroscope (Nikon, Japan) and Scanning Electron Microscope ( JEOL JSM 6510LA, Japan). Data were analyzed using Independent Sample T-Test (p<0.05). The average SBS value of group VIRK+MS was (16.97 + 7.67 MPa) higher than VIRK+SADRC (7.17 + 3.67 MPa). VIRK+Multi-step group has mixed failure, while VIRK+SADRC group has adhesive failure. Mixed failure shows strong bond between VIRK and enamel using Multi-step resin cement.

Impression stage is an important step in dentistry. The impression itself can be a media of infection transmisions due to microorganisms in the oral cavity. Therefore it is necessary to disinfect the impression before casting process. Dimensional stability is a factor that can affect accuracy of gypsum casts, meanwhile the elastomeric impression materials are not usually casted immediatelly. To determine effect of sodium hypochlorite and chlorhexidine gluconate disinfectans with various casting time, on the dimensional stability of condensation silicone gypsum casts. A total of 30 samples were made using condensation silicone impression materials. The impressions were disinfected in 5,25% sodium hypochlorite (NaOCl) or 0,2% chlorhexidine gluconate (Chx). The impression was casted in various time intervals 0, 12, 24, 36, and 48 hours with type III gypsum product. Dimensional changes were measured and the data obtained were analyzed using SPSS 17 with two-way ANOVA, post hoc LSD and unpaired t-test. Sodium hypochlorite caused greater dimensional changes (0,49%) than chlorhexidine gluconate (0,44%). Significant dimensional changes were detected after the casting was delayed for more than 24 hours (p <0.05). Sodium hypochlorite and chlorhexidine gluconate do not cause dimensional changes, assuming that condensation silicone impression is casted in maximum time of 24 hours. Disinfection of condensation silicone impression material in chlorhexidine gluconate presents better dimensional stability than sodium hypochlorite.
