Abstract: Nanofiller composite resin has small filler size which enhances its properties. However, these properties could decrease due to several factors. Acidic liquid such as coffee could reduce the hardness of composite resin. This study was aimed to analyze the effect of robusta and arabica coffee immersion on the hardness of nanofiller composite resin. A total of 27 composite resin samples were used and then were polished by using a soflex disc for 30 seconds on each roughness level. Samples were then divided into three groups, as follows: the control group with artificial saliva and the treatment groups with robusta coffee and arabica coffee. The composite resin molds were immersed in the three groups for 5 days. After five days of immersion, the hardness of the sample was tested by using a Vickers hardness tester. Artificial saliva as the control group had the highest mean hardness value of 112.98Â±8.67 VHN, followed by robusta coffee, and then by arabica coffee. The One Way Anova and post hoc LSD test showed that there were significant differences in all groups (p<0.05) except for the two treatment groups, namely robusta and arabica coffee groups which did not show any significant difference in the resin hardness (p>0.05). In conclusion, robusta and arabica coffee affect the hardness of the nanofiller composite resin, but there is no significant difference in the hardness between the robusta and arabica coffee groups.Keywords: composite resin hardness, nanofiller, robusta coffee, arabica coffeeÂ Abstrak: Resin komposit nanofiller memiliki ukuran filler kecil yang dapat meningkatkan fungsinya namun fungsi tersebut dapat menurun oleh beberapa hal. Cairan asam yang dikonsumsi seperti kopi dapat menurunkan kekerasan resin komposit. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman kopi robusta dan arabika terhadap kekerasan resin komposit nanofiller. Sampel resin komposit yang digunakan sebanyak 27 buah dan dilanjutkan dengan pemolesan menggunakan soflex disc selama 30 detik setiap tingkat kekasarannya. Sampel kemudian dibagi dalam tiga kelompok, yaitu kelompok kontrol dengan saliva buatan dan dua kelompok perlakuan dengan kopi robusta dan arabika. Sebanyak 27 buah resin komposit direndam ke dalam tiga kelompok tersebut selama lima hari kemudian diuji kekerasannya dengan vickers hardness tester. Saliva buatan sebagai kelompok kontrol memiliki nilai rerata kekerasan tertinggi sebesar 112,98Â±8,67 VHN, diikuti kopi robusta, dan nilai terendah yaitu kopi arabika. Hasil uji One Way Anova dan post hoc LSD menunjukkan terdapat perbedaan bermakna pada semua kelompok (p<0,05) kecuali pada kedua kelompok perlakuan yaitu antara kopi robusta dan arabika tidak menunjukkan adanya perbedaan kekerasan yang bermakna (p>0,05). Simpulan penelitian ini ialah kopi robusta dan arabika memengaruhi kekerasan resin komposit nanofiller namun tidak terdapat perbedaan kekerasan antara keduanya.Kata kunci: kekerasan resin komposit, nanofiller, kopi robusta, kopi arabika

Abstract: Enamel is the hardest structure of the tooth which contains 96% inorganic material. The hardness of enamel can be observed through the remineralization cycle. Remineralization can be produced by solution that contains ionic calsium and phosphate, such as milk. This study was aimed to determine the difference between immersed in cow milk and in pure soy milk on enamel hardness. This was an experimental laboratory study with the posttest only control group design. Samples were caries-free mandibular first premolars, obtained by using the simple random sampling. There were 27 specimens of human premolars to be measured for enamel hardness divided into three groups, as follows: immersed in artificial saliva, cow milk, and pure soy milk for 90 minutes (assuming consumption of cow milk/pure soy milk for 3 months). The hardness value was tested by using Vickers Hardness Tester with a load of 1000 grams for 10 seconds. The One Way Anova test showed that there were significant differences in tooth enamel surface among groups (p<0.05). The difference in enamel hardness between the group immersed in cow milk and the one immersed in pure soy milk group was not significant (p>0.05). In conclusion, there was no difference between immersion in cow milk and in soy milk on the enamel hardness. Cow milk and soy milk can become remineralizing agents to increase the enamel hardness.Keywords: pure cow milk; pure soy milk;Â hardness of tooth enamelÂ Abstrak: Email merupakan struktur terkeras dari gigi yang mengandung 96% bahan anorganik.

Jenis penelitian ialah eksperimental laboratorik dengan the posttest only control group design. Sampel penelitian ialah gigi premolar pertama rahang bawah yang bebas karies, diperoleh dengan simple random sampling. Sejumlah 27 spesimen gigi premolar manusia yang diukur kekerasannya dibagi menjadi tiga kelompok yang direndam dalam saliva buatan, susu sapi, dan susu kedelai murni selama 90 menit (asumsi konsumsi susu sapi/susu kedelai murni selama tiga bulan). Nilai kekerasan diuji menggunakan Vickers Hardness Tester dengan beban 1000 gram selama 10 detik. Hasil uji One Way Anova menunjukkan terdapat perbedaan permu-kaan email gigi yang bermakna (p<0,05).

Background: Tooth avulsion is the detachment of a tooth from its socket due to mechanical trauma. It was reported that a 26-year-old male patient was referred from the RSND Emergency Department to the dental clinic with complaints of loose front teeth of the upper jaw due to a traffic accident. From the intraoral examination, tooth 11 was partially detached from its socket, tooth 12 had an Ellis class II fracture, and a torn wound on the labial mucosa of the lower lip. Treatment of choice in this case is replantation and fixation of avulsed teeth, which aim to restore the physiological function of the teeth.Method: Treatments include extraoral root canal treatment and replantation and fixation of the arch bar. Result: Clinical and radiographic examinations during post-treatment control showed periodontal tissue healing and bone formation.Conclusion: It was concluded that the success rate of tooth replantation, in this case, was good, and using the right arch bar provided stability to the avulsed tooth, thereby accelerating the healing of the periodontal ligament

Coffee can cause discoloration in the hard tissues of teeth due to the presence of chlorogenic acid, which acts as a staining agent. Different types of coffee bean compositions have varying levels of staining agents. This study aims to investigate the influence of coffee bean composition (100% Arabica, 70%-30% Arabica-Robusta blend, 50%-50% Arabica-Robusta blend, and 100% Robusta) on the severity of tooth discoloration. This research is a quasi-experimental study with a pre-test and post-test control group design to assess the effect of coffee immersion on tooth color change (ΔE). The study involved 24 human premolar tooth samples divided into four treatment groups. Before treatment, the color of the samples was measured (pre-test data), and then the samples were immersed in a coffee solution for 48 hours. After immersion, the color of the samples was measured again (post-test data). Paired t-tests were conducted to determine the significance of differences between pre-test and post-test treatment. Subsequently, Kruskal-Wallis tests were performed to assess the significance of differences among the four treatment groups. Paired t-tests for all groups showed significant results (p < 0.05). Kruskal-Wallis tests indicated a significant difference among the four treatment groups (p < 0.05), with the highest tooth color change (ΔE) observed in the 100% Robusta coffee treatment group and the lowest color change in the 100% Arabica coffee treatment group. The composition of coffee bean types has an impact on the severity of tooth discoloration.
