Abstract

Alginate is one of the most widely used dental impression material used by dentists. When the process of syneresis and imbibitions occurs, it resulted in changes of dimensional stability of alginate and to prevent the occurrence changes in dimensional stability modification of impression material is done by adding cassava starch. The purpose of this study was to determine the effect of cassava starch in various concentrations of 40%, 50%, 60% into impression material of alginate with pouring of type III gypsum after 5, 10 and 15 minutes towards dimensional stability of denture model. This was a laboratory experimental study using a copper splint–metal (12,5 mm inside diameter). The total of 60 samples are classified to 12 groups. Samples were measured using digital calliper then analyzed by One-Way Anova test followed by LSD test. Based on One-Way Anova, the results shows significant result in addition of cassava starch concentration 40%, 50%, 60% into alginate with pouring of type III gypsum after 5 minutes (B1, A1.1, A2.1 dan A3.1) with p = 0,043 (p<0,05), after 10 minutes (B2, A1.2, A2.2 dan A3.2) with p = 0,005 (p<0,05) and after 15 minutes (B3, A1.3, A2.3 dan A3.3) with p = 0,003 (p<0,05). The result of LSD test showed a significant difference in all the groups with (p<0,05). The results showed the addition of cassava starch in various concentrations have influence on the dimensional stability of alginate impression material. The addition of 40% cassava starch into impression material of alginate has the best stability than other concentration.

Abstract

Conventional glass ionomer cement (GIC) is an aesthetic dental restoration materials that still used nowadays due to its own advantage, particularly the ability of GIC to release fluoride as anticariogenic. GIC restoration materials have low mechanical properties and low erossion resistance so GIC was modified by adding chitosan. The purpose of this research is to know the difference of surface roughness GIC without and with the addition of Chitosan after immersion in isotonic drink. There were 20 specimen that consists of two groups of treatment. The first group used conventional GIC and the second group used the GIC with the addition of Chitosan 10% v/v. All specimen cylindrical shapes with a diameter of 10 mm and a thickness of 2 mm. Both groups were kept immersed in isotonic drink for 24 hours. Surface roughness after immersion were measured using surface roughness tester TR200. Independent t-test results showed no meaningful difference (p>0.05) between conventional GIC (1,33 ± 0,34) and GIC with the addition of Chitosan 10% v/v (1,10 ± 0,29) after immersion. It can be concluded that the addition of Chitosan 10% v/v could decrease surface roughness of GIC although no meaningful difference.

Abstract

A recent technology of Bulk fill composite resin has been developed to save manipulation time. Bulk fill composite resinhas been claimed to have depth of cure up to 4 mm with a high degree of conversion. This paper will evaluate the role of bulk fill composite resin’s composition in increasingits degree of conversion. The degree of conversion is the percentage of carbon double bonds that were converted into single bonds as a result of polymerization. It is determined by its composition that contained filler, resin matrix and the photoinitiator. With the development and modifications of the composition, the bulk fill compositeresin can be obtained a high degree of conversion so that the expected properties can be achieved.

Abstract

Paradigm changes from replacement tissues into regenerating strengthened and start developed in dentistry. Tissue engineering in dentistry was developed such as material filler post extraction socket. The opened socket post extraction very range against contamination and infection. The current substances filler socket post extraction still not available. On the other hand, as maritime country Indonesia potentially in fisheries. The problem is the end of fish processing being fish waste, consisting of scales, spines, and fins. Fish waste is still underutilized. This study is study literature to discussing tissue engineering using fish waste as biomaterial filler post-extraction socket. Fish waste containing calcium, chitin, collagen, steroid, saponins, alkaloids, phenolics hydroquinones, and ninhidrin. That content is similar to bones, especially in the alveolar bone. Khitosan as the main derivatives of chitin is suspected play role in stimulating osteoblast activity as cell bone formed. Alkaloids, steroid, saponins, and phenolics hydroquinones are able to modulate activity of immune cells and antimicrobial. Based on the above analysis, it can be inferred that the fish waste is potentially as biomaterial socket filler based tissue engineering because it can stimulate regeneration of alveolar bone and antimicrobial.

Abstract

Early dental treatment on caries lesions of primary tooth is important as an attempt to maintain child’s oral health. But until recently the prevalence of dental caries among children still show a pretty high number. One reason for this is because it is still a lack of knowledge of dental health maintenance at home and also the presence of fear or anxiety towards dental treatments. Motivate a child to get the dental treatment requires efforts that can reduce the fear or increase the child’s interest in dental treatment. One of these efforts is to use a colored filling material. Children’s involvement in choosing the desired color can make dental filling as an exciting procedure without reducing the effectiveness of the treatment. This paper will discuss about the compomer as a filling material, which available in several color options.
