Abstract

Nanofiller composite resin (NCR) restoration has a major problem, namely color changes. Polishing are factors that determi-ne color change and if accompanied by the use of mouthwash for a long time can cause more significant color changes. The 0.2% chlorhexidine gluconate mouthwash is a mouthwash that is often used in the community because it has low toxicity. However, using the chlorhexidine gluconate 0.2% mouthwash in the long term can cause more significant discoloration. This study is aimed to determine the difference between discoloration of polished and unpolished NCR on the soaking of 0.2% chlorhexidine gluconate mouthwash. This purely experimental research with a pretest and posttest with control group design, using 24 samples of premolar teeth prepared with class II cavity design and then filled with NCR. The samples were then di-vided into 4 treatment groups, namely polished and non-polished NCR, 0.2% chlorhexidine gluconate mouthwash and aqua-dest. Soaking was carried out 24 hours a day for 5 days in an incubator at 37ºC. Color changes of each group were measured using shade guide Vita Classical. The results were analyzed descriptively and the normality was tested by the Shapiro-Wilk and Levene's homogenity test with significance value of 0.05. Mann-Whitney for the different test. Based on the results of this study, it is concluded that the discoloration of the polished NCR was smaller than that was not polished on the soaking of chlorhexidine mouthwash 0.2%

Abstract

Root canal filling is the most important stage in root canal treatment (RCT). Leakage at ⅓ of the tooth root can be affected by the type of cement, leading to RCT failure. This study analyzed leakage at the filling stage using calcium hydroxide (CaOH)2 and zinc oxide eugenol (ZOE) cements. The experimental laboratory study used samples of 16 maxillary central incisor teeth prepared by conventional techniques, divided into two groups and RCT was performed using the single cone technique. The samples were immersed in india ink for 7x24 hours, decalcified until transparent. The ink penetration depth was evaluated by stereo microscopy. As a result, the Ca(OH)2 cement group had 7 samples with a score of 1 and 1 sample with a score of 2. In the ZOE group, there were 5 samples with a score of 5 and 3 samples with a score of 3. The data were analyzed with an inde-pendent t-test to determine the differences between treatments (p<0.013). It was concluded that there was a significant differ-ence between the two cements, namely Ca(OH)2 cement showed better sealing ability than ZOE.
