Latar Belakang : Resin komposit nanohibrida merupakan bahan restorasi gigi yang dikembangkan untuk memperoleh sifat fisik dan mekanik yang lebih baik. Polimerisasi material tersebut akan menyisakan sejumlah monomer yang tidak bereaksi. Peningkatan jumlah monomer yang tidak bereaksi dapat menurunkan kekuatan mekanik bahan restorasi gigi. Tujuan : Untuk mengetahui pengaruh preheating dan heat treatment terhadap kekuatan kompresi resin komposit nanohibrida. Metode : Eksperimental murni dengan rancangan penelitian post test only control group design. Empat puluh delapan sampel resin komposit berbentuk silinder dengan diameter 5 mm dan tebal 2 mm dibagi menjadi 6 kelompok yaitu, kelompok preheating 37ÂºC, 60ÂºC, kelompok heat treatment 120ÂºC, 170ÂºC, kelompok kontrol negatif dan kontrol positif. Seluruh kelompok dilakukan uji kekuatan kompresi menggunakan Universal Testing Machine. Hasil : uji one way ANOVA menunjukkan perbedaan yang signifikan dengan nilai p>0,05 (0,000) pada sebagian besar kelompok hasil. Kesimpulan : penelitian ini adalah kelompok heat treatment dengan suhu 170ÂºC memiliki nilai kekuatan kompresi tertinggi, sedangkan nilai yang paling rendah adalah kelompok kontrol negatif.

Denture stomatitis is an infection of the mucosa caused by bacteria such as Staphylococcus aureus (S. aureus) accumulating on the denture. Garlic (Allium sativum) contains antibacterial compounds that can be used as an alternative denture cleanser. The purpose of this study was to determine the inhibition effect of immersion in effervescent garlic ethanol extract (Allium sativum) against Staphylococcus aureus growth on heat cured acrylic dental plate. This research was a laboratory experiment in vitro using 40%, 50%, and 60% effervescent garlic ethanol extract. The samples were 12 pieces (n = 12) of heat cured acrylic plates which were divided into 3 treatment groups then incubated in S. aureus suspension for 24 hours and then immersed in an effervescent garlic ethanol extract for 6 hours. Bacterial colonies were counted using a colony counter and the data were analyzed using the One-way ANOVA and LSD Post hoc tests. The statistical analysis showed that the number of S. aureus colonies decreased along with an increased concentration of garlic ethanol extract. The results of the analysis showed that the 60% effervescent garlic ethanol extract had a significantly lower mean number of colonies compared to the 40% and 50% effervescent garlic ethanol extracts (p ≤ 0.05). This research concluded that effervescent garlic ethanol extract prevented the growth of S. aureus on the heat cured acrylic dental plate.

Child malnutrition can happen because of lack of nutrition during pregnancy. Malnutrition can cause low birth weight in babies. This can cause jaw and alveolar bone abnormalities that can lead to malocclusion, periodontitis, and others. This condition can affect bone cells, such as osteoblast and osteoclast. Vitamin D3 supplementation accompanied by protein realimentation may promote optimum bone growth. This research aims to investigate the effect of protein realimentation and vitamin D3 on osteoblast and osteoclast of malnourished rat pups’ maxilla. In this research, the rat pups were divided into 5 groups: a positive control group (K+), a negative control group (K-), and 3 treatment groups (P1, P2, and P3). The subjects of this research were 10 male and 30 female Wistar rats. A condition of malnutrition was induced in the rat pups and they were given vitamin D3 supplementation with protein realimentation. Rat pups in each group were euthanized on the 22nd day to observe the number of osteoclast and osteoblast in the maxilla. The results showed that the number of osteoblasts between normal and malnourished rats was significantly different (p value < 0.05), but the number of osteoclasts between rats in the control and treatment groups was not significantly different. Administration of vitamin D3 may affect the number of osteoblasts and may not affect the number of osteoclasts on bone. The effective dose of vitamin D3 is 0.36 IU/day.

Background: Composite resin is a material that is widely used for caries restoration, enamel abrasion, and aesthetic needs because of the good fit with teeth. Restorative materials that release fluoride ions may prolong the therapeutic and protective effects of the enamel. Nowadays, composite resins have been developed a new hybrid restorative material, named giomer. Giomer containing pre-reacted glass-ionomer (PRG) which can release and recharge fluoride ions. Composite resins have a disadvantage, a presence of shrinkage during polymerization, which can cause gaps between the tooth surface and composite resin. Preheating is carried out before irradiation with conventional oven. Preheating makes the composite resin stronger, reduces viscosity makes it easier to adapt and apply, and improves mechanical properties. This study aims to determine the effect of preheating on surface hardness.Method: The research sample used is 27 pieces cylinder-shaped with 5 mm diameter and 2 mm depth. The number of treatments was divided into 3 treatment groups. The treatment groups were divided based on the preheating treatment temperature of 37Â°C, 60Â°C, and control group. The surface hardness test was carried out using Vicker's microhardness tester.Result: The statistical One Way ANOVA test showed a significant result between the groups (p<0,05). LSD test (Least Significance Difference test) showed a significant result between the treatment temperature of 37Â°C, 60Â°C, and control group (p<0,05).Conclusion: The result of the giomer surface hardness test with preheating showed a higher result than the control group. The preheating group with a temperature of 60Â°C had the highest result.
