This book was released on 2010 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: INTRODUCTION: The objective of this study was to determine the effect of phosphoric acid etching prior to application of self-etching primer on orthodontic bonding in terms of shear bond strength and the adhesive remnant on the enamel surface at debonding. METHODS: Fifty-one extracted human premolars were pumiced, rinsed, dried, and then subjected to three different treatments: Group 1: no phosphoric acid etching + Transbond Plus SEP; Group 2: 15-second etching with 37% phosphoric acid + rinsed + dried + Transbond Plus SEP; Group 3: 30-second etching with 37% phosphoric acid + rinsed + dried + Transbond Plus SEP. Precoated metal brackets (3M Unitek, APC Plus, Victory brackets) were then bonded following the manufacturer's recommendation. An Instron Universal Testing Machine was used to test shear bond strength (SBS) at a crosshead speed of 0.5 mm/min. Adhesive remnant index (ARI) was assigned to all specimens under a 16 times magnification using a light microscope. RESULTS: One-way repeated measured analysis of variance test (ANOVA) revealed no significant differences in shear bond strength among all three groups. Kruskal Wallis test revealed that there was a significant difference in ARI score between Group 1 when compared to Groups 2 and 3. Two-way analysis of variance was used to examine any statistical difference in frequency of enamel fracture craters among the three groups. CONCLUSION: There was no statistical difference in shear bond strength between the three groups. Most specimens demonstrated adequate shear bond strength (>/= 6 MPa) for routine clinical application. Etching enamel with phosphoric acid prior to the use of Transbond Plus SEP resulted in more adhesive remaining on the enamel surface. The removal of this excess surface cement may lead to increased enamel loss during post debonding clean up.

Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively reviews bonding to enamel, dentin and cementum and analyses relevant adhesion mechanisms. It is addressed to both the dental researcher and the clinician. Emphasis is placed on the characterization of material interfaces with dental tissues in situ. The volume also stresses the importance of appropriate experimental protocol design in facilitating clinically-relevant research methods, clarifies the mechanisms of adhesion of polymeric materials to hard dental tissues and furnishes a handy reference for routine clinical procedures in restorative and prosthetic dentistry as well as orthodontics. The book introduces important aspects of the chemistry of dental materials and their adaptation to dental hard tissues. It also analyses interfacial phenomena occurring during application of materials, including mechanical properties, and structural-compositional alterations. The text presents the current instrumental approaches in studying related issues and a summary of the current status of theories concerning bonding to dental tissues. This work, in its scope and scientific content, provides an in-depth view of the way in which aesthetic dentistry is currently being practiced.

Download or read book Effects of Etching Duration on the Surface Roughness Surface Loss Flexural Strength and Shear Bond Strength to a Resin Cement of E max Cad Glass Ceramic written by Hanan Al-Johani and published by . This book was released on 2017 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: EFFECTS OF ETCHING DURATION ON THE SURFACE ROUGHNESS, SURFACE LOSS, FLEXURAL STRENGTH OF E. MAX CAD GLASS CERAMIC AND SHEAR BOND STRENGTH TO A RESIN CEMENT Background: Long-term retention of ceramic restorations is dependent on the bond strength of the luting resin to both the tooth and porcelain substrates. In order to achieve successful bonding, the surface of the porcelain substrate must be modified to increase the surface roughness, and this can be achieved chemically by hydrofluoric (HF) acid etching. However, prolonged HF acid etching has shown to have a weakening effect on the evaluated lithium disilicate glass-ceramics. Therefore, it is essential to quantify the required etching duration of HF acid to minimize the possible deleterious effects on ceramic strength while maximizing the bond strength to tooth structure. Objectives: To evaluate the effects of HF acid etching duration on the surface roughness, surface loss, flexural strength, and shear bond strength of IPS e.max CAD (Ivoclar Vivadent) lithium disilicate-based glass ceramic to a resin cement. Hypothesis: The differences in HF acid etching durations will not have a significant effect on the surface roughness, surface loss, flexural strength, or shear bond strength of IPS e.max CAD to a resin cement. Methods: 168 specimens were prepared from IPS e.max CAD blocks. All specimens were polished and sonically cleaned in distilled water. Specimens were fired in the vacuum pump furnace according to the manufacturer's instructions. Specimens were then divided into 4 groups, according to etching durations, then further divided into 3 subgroups, according to the properties tested. Group A was not etched (control), Groups B, C and D were etched with 5-percent HF acid (IPS Ceramic Etching gel, Ivoclar Vivadent) for 20 s, 60 s and 90 s respectively. The morphologies of both etched and non-etched surfaces in specimens of subgroup 1 of each etching group (n = 16/group) were observed under scanning electron microscopy (SEM). In addition, non-contact surface profilometry (Proscan 2000) was used to calculate the surface loss and to examine the surface roughness of the etched ceramic surfaces and roughness values (Ra, Rq) were documented for each group. Furthermore, etched specimens of subgroup 2 (n = 16/group) were silanated (Monobond Plus, Ivoclar Vivadent) and cemented with a resin cement (Multilink Automix, Ivoclar Vivadent). The shear bond strength (SBS) was measured using a universal mechanical testing machine. For each etching group, subgroup 3 specimens (n = 10/group) were loaded to failure in a three-point bending test to measure their flexural strength values using a universal mechanical testing machine. Data for surface roughness, surface loss, and flexural strength were analyzed using one-way analysis of variance (ANOVA), to identify the significant effects of different HF acid etching durations. Data for shear bond strength test were analyzed using two-way ANOVA to test the effects of etching duration, storage for 24 hours/thermocycling, and their interaction. All pair-wise comparisons from ANOVA analysis were made using Fisher's Protected Least Significant Differences to control the overall significance level at 5 percent. Results: Difference in HF etching durations did not have a significant effect on surface roughness values Ra or Rq (p = 0.3408; p = 0.3245) respectively, but had a significant effect on surface loss (p = 0.0006). SBS values were not significantly different between experimental groups (p = 0.4650); however, SBS values after 24-h storage were significantly higher than that found after thermocycling (p = 0.0166) among different etching durations. Finally, different HF etching durations did not have a significant effect on flexural strength values (p = 0.1260). Conclusion: Within the limitations of this study, different HF etching durations did not have a significant effect on surface roughness, flexural strength, or shear bond strength of IPS e.max CAD. However, the different etching durations significantly affected the surface loss of the lithium disilicate glass ceramics.

This book was released on 2008-04-15 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aesthetic dentistry has become increasingly important to dentists and their patients. This book is designed as a springboard to assist clinicians in developing the aesthetic potential of restorative procedures. The book marries evidence-based principles with handy hints and tips the author has distilled from years of clinical experience. This combination of scientific principles with ‘real world’ practice will boost the confidence of budding aesthetic practitioners and clinical dental students. The book focuses on the principles of aesthetic work across the dentist's repertoire, rather than concentrating on one particular technique. For this reason, it will add value to the range of daily restorative work in the dental surgery.
