“…The reaction of hydrogen peroxide with hydroxyapatite which is the main inorganic material of the dentine can be described as follows: H 2 O 2 + Ca 10 (PO 4 ) 6 (OH)à10CaO + 3P 2 O5 + H 2 O. 18 The different calcium and phosphorus percentages in the four treatment groups were probably due to the different amounts of residual free radicals resulting from the breakdown of 35% hydrogen peroxide in the four treatment groups. The different amounts of the residual free radicals will cause different demineralization levels.…”

Post bleaching procedures often have free radicals trapped in dentin tubule and interprismatic enamel, leading to demineralization and denaturation. Sodium ascorbate is an antioxidant substance known to bind residual free radicals to stop demineralization and denaturation. The purpose of the study was to assess the calcium and phosphorus loss from the dentin surface following bleaching by 35% hydrogen peroxide and reversal by 35% sodium ascorbate andthe surface structure of the dentin. Six sound premolars were divided into their crown and root sections, with the crown subsequently being cut into four equal parts to obtain 24 samples. The calcium and phosphorus contents as well as the surface structure of the dentin were assessed using SEM-EDX. These were then divided into four groups, each containing six samples. Group A (control): the samples were bleached by 35% hydrogen peroxide, immersed in an artificial saliva, stored in an incubator at 37 °C for seven days. Group B: the samples were bleached by 35% hydrogen peroxide followed by the application of 35% sodium ascorbate for 5 minutes (once). Group C: the samples were bleached by 35% hydrogen peroxide followed by the applications of 35% sodium ascorbate (twice). Group D: the samples were bleached by 35% hydrogen peroxide followed by the applications of 35% sodium ascorbate (threetimes). The calcium and phosphorus contents as well as the surface structure of the dentin were re-assessed using SEM-EDX at the same locations. The results of one-way ANOVA indicated a difference in the calcium loss in the four treatment groups (p<0.05), but there was no difference in the phosphorus loss. An LSD test showed that there was a difference in the calcium loss between group A and groups C and D or between group B and groups C and D. The dentin tubules in group A were larger than group B, C and D. The frequency of 35% sodium ascorbate application had an effect on the calcium loss and the surface structure in the dentin bleached by 35% hydrogen peroxide.

“…1 The advantages of nanohybrid composite resin includes good colour stability, good surface finish and less cure shrinkage. 2 Nanohybrid composite resins have additional components in the resin matrix, namely nanoparticles and nanocluster. 3 This combination can reduce particle interstitial distance, thereby increasing filler resistance, physical properties, mechanical properties and retention.…”

The different effects of preheating and heat treatment on the surface microhardness of nanohybrid resin composite

Background: A composite resin is used as restorative material in dentistry because it has the same colour as dental enamel, is easy to use in an oral cavity and offers good biocompatibility. Based on the size of filler, composite resin is divided into types, one of which is a composite resin nanohybrid. An important mechanical property of restorative material is microhardness. The mechanical properties of restorative material is highly affected by both polymerisation and heating process. There are many methods to improve composite resin’s microhardness, including preheating and heat treatment. Purpose: The purpose of this study was to evaluate different effects of preheating and heat treatment on the microhardness of nanohybrid composite resin. Methods: This study is an experimental laboratory research with post-test-only group design. Samples were divided into six groups: preheating groups at temperatures of 37oC and 60oC, heat treatment groups at temperatures of 120oC and 170oC, a negative control group and a positive control group. Afterwards, the resulting data were analysed using one-way ANOVA. Results: The result based on the one-way ANOVA test indicated that there was a difference in microhardness in each group with a significance of 0.000 (p<0.005) between preheating and heat treatment. Conclusion: The conclusion of this study was the best microhardness of composite resin nanohybrid is the heat treatment group at temperature 170oC.

Warna gigi adalah salah satu masalah estetika di masyarakat. Kondisi ini dipengaruhi oleh faktor ekstrinsik dan intrinsik. Karbamid peroksida 35% adalah bahan yang disetujui oleh American Dental Association (ADA) sebagai pemutih gigi yang aman dan efektif. Strawberry (Fragaria x annanassea) adalah bahan alami yang mengandung asam elegat sehingga dapat digunakan sebagai pemutih gigi. Tujuan penelitian ini adalah untuk mengetahui perubahan warna gigi setelah perendaman jus F. x annanassea 100% dan karbamid peroksida 35%. Metode penelitian ini merupakan eksperimental murni laboratoris. Sampel yang digunakan sebanyak 24 gigi premolar pascapencabutan yang telah didiskolorasi menggunakan teh. Spesimen dibagi menjadi 2 kelompok, kelompok pertama dilakukan perendaman jus buah F. x annanassea 100% dan kelompok kedua dilakukan perendaman dengan karbamid peroksida 35%, masing-masing selama 30, 60 dan 90 menit. Kemudian warna gigi setelah direndam diukur dengan spektrofotometer dan shade guide untuk menentukan perubahan warna sebelum dan sesudah perlakuan. Data dianalisis menggunakan Two Way Anova dan Kruskal-Wallis. Hasil penelitian ini menunjukkan bahwa perendaman jus F. x annanassea 100% dapat membuat gigi menjadi lebih cerah, dengan tingkat kecerahan yang hampir sama dengan menggunakan karbamid peroksida 35%. Kesimpulan penelitian ini adalah jus buah F. x annanassea dapat digunakan sebagai bahan alternatif untuk memutihkan gigi.
