Abstract

Immersion and spraying with disinfectant solution are the effective disinfection methods for alginate impression. However these methods causes dimensional changes on impression. Therefore mouthwash, which also has disinfectant function on microorganism can be used as mixing solution for alginate impression material. The aim of this study is to analyze antibacterial capacity of mouthwashes that used as admix solution for alginate impression. Samples was made from alginate impression material in tablet form with 15 mm diameter and 1 mm thickness. Total samples are 35 , 5 for admix with aquadest as control, chlorhexidine 0.1%, povidon iodine, sodium fluoride 0.1% wv, respectively. Samples were put on incubated Staphylococcus aureus in petri dish and kept in incubator for 24 hours at 37°C. Immersion was performed by dipping 15 samples of hygedent admix with aquadest into mouthwash liquids for 15 minutes. Inhibition zone was measured by using digital calliper. Statistic analysis was performed by using ANOVA one way and unpaired t-test. The admix with chlorhexidine 0.1% show the inhibition zone by 8.09 mm, povidon iodine 0.52 mm, and sodium fluoride 0.1% wv 2.91 mm. By using immersion method they show 7.63 mm inhibition zone for chlorhexidine 0.1%, 1.51 mm for povidon iodine, and 0.91 mm for sodium fluoride 0.1% wv. There are insignificant differences between admix and immerse with chlorhexidine 0.1% solution (p= 0.25). It can be concluded that chlorhexidine mouthwash 0.1% has the equal antibacterial capacity when used for admix solution nor immerse the alginate impression.

Abstract

Radiopacity is an important characteristic for restorative materials as dentists have got different abilities in interpreting a lesion or caries in a radiograph. The enforcement of secondary caries diagnosis is a challenge for dentists because they often mistake the diagnosis for restorative materials with low radiopacity. This study aims to determine the differences in the average radiopacity values of certain restorative materials by using conventional and digital radiographs. Moreover, to know the right types of radiographs in distinguishing between radiopacity of certain restorative materials and radiodensity of secondary caries. This is an analytical descriptive study with cross sectional design. The sample was divided into 10 groups of 6, which is dental radiograph filled with glass ionomer cement, resin modified glass ionomer cement, nanofiller and micro hybrid composites as well as teeth with secondary caries which were obtained from conventional and digital radiographs. Next, conventional and digital radiographs were interpreted by observations of 5 dental specialists in which measurement was done by using Image J software to get the average radiopacity values of secondary caries and each restorative material. The results showed that the average radiopacity values for glass ionomer cement are 177.633 ± 6.465 and 187.879 ± 9.305, resin modified glass ionomer cement are179.498 ± 5.597 and 192.078 ± 11.006, composite nanofillers are 194.847 ± 4.952 and 184.401 ± 9.170, microhybridcomposites are 189.109 ± 4.251 and 179.585 ± 6.809, finally secondary caries are 161.772 ± 9.256 and 109.988 ± 7.684 for conventional and digital radiographs respectively. Then the data was analyzed by using T test with significance value of p <0.05. As a conclusion, this study shows no significant difference in the radiopacity of four restorative materials if compared between conventional and digital radiographs while digital radiograph shows significant difference between radiopacity values of restorative materials and secondary caries. Whereas, conventional radiograph does not show significant difference between restorative materials and secondary caries.

Abstract

Resin modified glass ionomer cement as restorative material used in dentistry especially in primary teeth. Fresh milk is often consumed by children as daily drink and it contains lactic acid. The aim of this study was to evaluate surface roughness of resin modified glass ionomer cement after immersed in fresh milk for 2, 4, and 6 hours. Samples were disc shape resin modified glass ionomer cement with size 5 mm in diameter and 2 mm in thickness. Totally 24 samples were divided into 3 groups (n=8), group immersed for 2 hours, group immersed for 4 hours, and group immersed for 6 hours. Fresh milk was pure cow’s milk that harvest in the morning by the farmer. Surface roughness measurements was done before and after immersed using a profilometer (Surfcorder SE-300, Laboratory Ltd, Japan). Results showed surface roughness change were 0.0217 ± 0.005 μm for groups A, 0.0366 ± 0.006 μm for groups B, and 0.0555 ± 0.004μm for groups of 6 hours. One Way Anova test showed significant differences between groups (p <0.05). It can be concluded that there was significant increased on surface roughness of modified resin ionomer cement after immersed in fresh milk for 2, 4 and 6 hours.

Abstract

Introduction: Orthodontic elastomeric chain is polyurethane elastomer that is widely used among orthodontists due to its functions. Chlorhexidine (CHX) and sodium fluoride (NaF) are listed in mouthwash composition which could affect the mechanical properties of the elastomeric chain. This study was aimed to analyze the effect of sodium fluoride in chlorhexidine mouthwashes on force decay and permanent deformation of orthodontic elastomeric chains. Methods: This research is an experimental analytic laboratory with pretest-posttest control group design. 150 samples of orthodontic chains were divided into three groups. Group 1: artificial saliva (control group); Group 2: 0,1% chlorhexidine gluconate solution (CHX); Group 3: 0,1% chlorhexidine digluconate with sodium fluoride solution (CHX-NaF). The orthodontic elastomeric chain was stretched and maintained at a standardized distance equivalent to a force of 300 g. The measurement of force decay and permanent deformation were performed with digital force gauge and digital caliper (0.01mm) at intervals of the first, seventh, fourteenth, twenty-first, and twenty-eighth days, respectively. Results: The force decay and permanent deformation of the elastomeric chain compared among three groups (control, CHX mouthwash and CHX+NaF mouthwash) showed did not have any significantly different (p-value>0,05) at the first, seventh, fourteenth, twenty-first, and twenty-eighth days, respectively. Conclusion: Sodium fluoride in chlorhexidine mouthwash showing no difference among saliva, CHX mouthwash and CHX+NaF mouthwash on force decay and permanent deformation of elastomeric chain.
