Tooth sensitivity arises during or after an in-office bleaching was performed is usually overcome by using desensitizing agent with or without fluor. So far, desensitizing method applied only reduces tooth sensitivity but it had not overcome demineralization problem yet. This study was aimed to determine the influence of an applicationprocess and fluoride containing desensitizing agent in tooth mineral lossEight teeth were divided into four parts. Six specimens were smoothened using agate mortar. One mg of powder was inserted into the sample holder and mounted ongoniometer heads to examine mineral content before treatment using X-Ray Diffraction (XRD). Twenty-four specimens were classified into four groups. In group I, 0,1 ml desensitizing agent without fluoride (CPP-ACP) was applied for 30 minutes after an in-office bleaching using 40% Hydrogen Peroxide was performed, while in group II, CPP-ACP was applied before and after an in-office bleaching was performed. In group III 0,1 ml fluoride containing desensitizing agent (CPP-ACFP) was applied for 30 minutes after in-office bleaching using 40% Hydrogen Peroxide was performed, while in group IV fluoride containing desensitizing agent was applied before and after an in-office bleaching was performed. Finally, all of the specimens were measured in their after-treatment mineral contain. Mann Whitney test showed that the lowest mineral lost was detected in group IV (4500). Fluoride containing desensitizing agent applied before and after an in-office bleaching effectively reduced mineral loss.

Abstract

Matrix system used bis-GMA was reported hazardously. An alternative monomer such as 1,6-hexanediol dimethacrylate(HDDMA) was under research. The aim of this study was to evaluate residual monomer content of HDDMA basedmatrix compositions on FRCs (fiber-reinforced composites). Three monomers based on bis-GMA (Sigma-Aldrich,USA),methylmethacrylate (MMA, ProSciTech, Australia), HDDMA (Esstech, USA) were used and also camphorquinone (CQ,Esstech, USA), N,N-cyanoethyl methylaniline (CEMA, Esstech, USA), E-glass fibers (StickTech, Finland). The matrixratios (weight %) were 78.4% bis-GMA+19.6% MMA+1.0% CQ+1.0% CEMA (control-group), 78.4% HDDMA+19.6% MMA+1.0% CQ+1.0% CEMA (EXP-1group), and 49.0% HDDMA+49.0% MMA+1.0% CQ+1.0% CEMA(EXP-2group). Samples with fibers embedded in matrix were light-cured then powdered. Powder of 150mg was dilutedin acetonitrile to 10ml. The solution was filtered then injected into HPLC (20µL). Residual monomer content wasevaluated by mobile phase of acetonitrile and water of 7:3, flow rate 1mL/minute. The size of column was C185µ,125mm length, 4mm diameter. UV detection used 275nm. Data were analyzed by ANOVA. The result showed theaverage of residual monomer content (in %) was: 0.02125±0.00018 (control-group), 0.01660±0.00016 (EXP-1group),0.01676±0.00033 (EXP-2group). The ANOVA showed significant difference of monomer content among the groups(p<0.05). The LSD showed significant difference between EXP-1 and control-groups; also between EXP-2 and controlgroups (p<0.05). There was no significant difference between EXP-1 and EXP-2 groups (p>0.05). In conclusion, a resinmatrix system based on HDDMA–MMA (EXP-1 and EXP-2 groups) revealed significant difference of residualmonomer content to bis-GMA–MMA (control-group) system. The HDDMA-MMA matrix system had less residualmonomer content than bis-GMA-MMA.

Abstract

Nickel-chromium alloy is a preferred material for fixed partial denture due to its low cost as well as good physical and mechanical properties. Tooth brushing using toothpaste produces abrasion on restoration, especially in a long period. This study aimed to observe the effect of toothbrushing duration on the wear of nickel-chromium alloy. Twenty four specimens of nickel-chromium alloy (Metal 4all, Ivoclar, USA) in 30X15X1mm3 dimension were treated using tooth brushing simulation machine (wear test machine, pin on plate unidirectional movement type) and toothpaste (modification of Balsam formula). The brushing durations were 30.9, 77.25, 123.6, and 154.5 hoursas the simulation of 2, 5, 8, and 10 years tooth brushing. Surface roughness and weight difference as abrasion indicator were measured and analyzed using one-way ANOVA followed by LSD test. Tooth brushing duration of 2, 5, 8, and 10 years increased nickel-chromium alloy surface roughness (Ra) by 0.16, 0.39, 0.43, and 0.56µm with weight loss of 8%, 15%, 23%, and 32 %, respectively. These differences were statistically significant (p <0.05). The result of LSD test showed a significant effect (p <0.05) between groups of toothbrushing duration. The increase of surface roughness affects the increase of wear volume of nickel-chromium alloy indicated by R = 0.11 for brushing duration of 2, 5, 8, and 10 years. The conclusion of this study was 10 years tooth brushing promoted wear on nickelchromium alloy, whichwas indicated by the increase in surface roughness and weight loss.

Abstract

Dental ceramics are widely used and studied in dentistry because they are durable, aesthetically appealing and provide excellent biocompatibility. All glass-ceramic surfaces must be etched using hydrofluoric acid (HF) to increase surface roughness determined by roughness average (Ra) before cementation to a tooth surface. This research aimed to analyze the effect of hydrofluoric acid surface treatment concentration on the surface roughness of lithium disilicate glass ceramic. A total of fifteen discs of lithium disilicate glass ceramic were prepared (10mm in diameter and 1mm in thickness). Specimens were divided into 3 groups (n=5). Group A (control) was no treatment, group B was etched by 5% HF for 2 min, and group C was etched by 9.5% HF for 2 min. The etched surfaces were observed by Scanning Electron Microscope (SEM). The measurement of the Ra of the lithium disilicate glass ceramic was determined with surface roughness tester machine. The results showed that the means of Ra (μm) were 0.096±0.009μm, 0.608±0.054μm, and 0.892±0.101μm in group A, B, and C, respectively. The one-way ANOVA showed there was an effect of hydrofluoric acid surface treatment concentration on the surface roughness of the lithium disilicate glass ceramic. The post hoc test showed there was a difference of Ra (μm) among the experimental study groups (p<0.05). In conclusion, the concentration of hydrofluoric acid influences Ra of lithium disilicate glass ceramic.

Abstract

Retainer dibutuhkan untuk membantu menstabilkan posisi gigi geligi selama proses reorganisasi jaringan periodontal berlangsung. Retainer FRC ortodonsi dikembangkan sebagai alternatif material estetika serta aman bagi pasien alergi terhadap nikel. E-glass fiber lebih sering digunakan sebagai retainer ortodonsi. Penelitian ini bertujuan untuk mengkaji pengaruh komposisi glass fiber non dental dan penambahan silane terhadap kekuatan geser FRC sebagai retainer ortodonsi. Subjek penelitian terdiri dari 9 kelompok perlakuan dengan 3 jenis glass fiber yang berbeda yaitu glass fiber non dental A (LT, Cina), B (CMAX, Cina) dan C (HJ, Cina). Masing-masing glass fiber diberi perlakuan yang bervariasi yaitu tanpa penambahan silane, penambahan silane 1x dan 2x. Subjek penelitian direndam dalam akuades dan disimpan pada suhu 37ºC selama 24 jam sebelum dilakukan uji kekuatan geser dengan menggunakan alat Universal Testing Machine. Hasil penelitian dianalisis variansi dua jalur dan post hoc Tukey untuk mengetahui perbedaan statistik masing-masing kelompok. Hasil penelitian menunjukkan bahwa glass fiber non dental A dengan penambahan 2x silane memiliki rerata kekuatan geser tertinggi (12,72±2,02 MPa) sedangkan glass fiber non dental B tanpa penambahan silane memiliki rerata kekuatan geser terendah (6,96±1,69 MPa). Terdapat perbedaan bermakna antara komposisi fiber maupun penambahan silane terhadap kekuatan geser FRC (p<0,05). Tidak terdapat perbedaan bermakna pada letak kegagalan FRC (p>0,05). Berdasarkan hasil penelitian dapat disimpulkan bahwa komposisi SiO2 dan Al2O3 yang tinggi pada glass fiber non dental serta penambahan silane dapat meningkatkan kekuatan geser FRC. The Effect of Non Dental Glass Fiber Composition and Silane Addition on The Shear Bond Strength of Fiber Reinforced Composite as An Orthodontic Retainer. Retainers are required to stabilize the position of the teeth to permit reorganization of periodontal tissue. FRC orthodontic retainer was developed as an alternative material aesthetic and safe for nickel allergic patients. E-glass fiber is commonly used as an orthodontic retainer. The purpose of this study was to assess the effect of non dental glass fiber composition and silanes addition on the shear bond strength of the FRC as an orthodontic retainer. This study consisted of 9 treatment groups with three different types of non dental glass fiber, namely non dental glass fiber A (LT, China), B (CMAX, China) and C (HJ, China). Each glass fiber was given a variation treatment, without silanes, one time and two times of silanes addition. All the samples were stored in distilled water at 37ºC for 24 hours and subsequently tested for shear strength by using Universal Testing Machine.The groups were submitted to two way ANOVA analysis of variance with Tukey post test to verify the statictical difference between groups. The results showed that a non dental glass fiber A with two times of silanes addition has the highest shear bond strength (12,72±2,02 MPa), meanwhile a non dental glass fiber B without silane addition has the lowest shear bond strength (6,96±1,69 MPa). There were significant differences between the composition of glass fiber and the addition of silane toward the shear bond strength of FRC (p<0,05). No significant differences in debonded locations of FRC (p>0,05). Based on the results of this study concluded that the composition of the high SiO2 and Al2O3 in the non dental glass fiber  and the silanes addition can increase the shear bond strength FRC.
