Abstract

Background: Root canal preparation produces smear layer. Smear layer removal is mandatory before obturation, which could be achieved by using root canal irrigants such as EDTA 17% and maleic acid 7%. As reported in previous research, irrigant solutions combined with sonic irrigation systems can remove the smear layer. This study aims to assess the effectiveness of irrigation solution with sonic activation tip placement at 2 mm and 4 mm from working length within 30 seconds in eliminating the smear layer in the apical third of the root canal.Method: 120 extracted single-rooted premolars decoronated and prepared with reciprocating file (#25/06), then randomly divided into six groups for final irrigation. Group 1: EDTA 17% + activation tip 2 mm from working length, Group 2: Maleic acid 7% + activation tip 2 mm from working length, Group 3: Distilled water + activation tip 2 mm from working length, Group 4: EDTA 17% + activation tip 4 mm from working length, Group 5: Maleic acid 7% + activation tip 4 mm from working length, Group 6: Distilled water + activation tip 4 mm from working length. Teeth were split into half using chisel and mallet and observed by Scanning Electron Microscope with 1000x magnification.Result: Kruskal-Wallis test showed significant differences among the groups (p<0.001).Conclusion: Sonic activation tip placement influences the cleanliness of the apical third of the root canal

Abstract

Background: The very rapid development of technology for aesthetic treatment results has given rise to composite resin namely one shade composite resin. One shade composite resin has a chameleon effect that can copy all tooth colors using just one color. However, this composite resin can change color which causes patient dissatisfaction with the treatment results because it interferes with aesthetic value and appearance. This color change is influenced by the presence of color pigments and the acidic pH in the food and drinks, specifically red wine. Objective: To examine the effect of red wine consumption on the color stability of one shade composite resin. Methods: This research used sixteen one shade composite resins, consisting of 2 different brands in cylindrical shape (diameter: 10 mm; height: 2 mm) and allocated to 2 different groups, that is the control and treatment groups for each type of composite resin. Control groups were immersed in artificial saliva fo 6 days within 144 hours. Treatment groups were immersed in red wine for 4 days within 96 hours, followed by immersion in artificial saliva for 2 days within 48 hours. Color measurements were measured using vita easyshade V. Results: The ANOVA Two Way results showed that there were significant color change (p<0,05). Conclusion: There is an effect of immersion red wine on the color stability of one shade composite resin.
