Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to evaluate the shear-peel bond strengths of orthodontic attachments bonded to enamel surfaces under varying conditions. A light-cured composite adhesive was compared to a cyanoacrylate adhesive and a composite hybrid adhesive. The shear-peel bond strengths in this study are stated as 24 hours vs. 6 months and were as follows: Transbond(tm) XT/dry (10.57 +- 2.83 MPa vs 12.23 +- 3.14 MPa), Assure(tm)/dry (6.93 +- 2.2 MPa vs 8.18 +- 1.39 MPa), Smartbond(R)/dry (3.91 +- 1.17 MPa vs 4.11 +- 1.96 MPa), Transbond(tm) XT/moist (0.14 +- 0.31 MPa vs 0 +- 0 MPa), Assure(tm)/moist (6.03 +- 1.77 MPa vs 6.86 +- 2.81 MPa), and Smartbond(R)/moist (3.22 +- 0.52 MPa vs 2.4 +- 0.96 MPa). There was a statistically significant difference (p 0.05) between (1) the different adhesives (2) the dry and moist conditions of Transbond(tm) XT. There was no statistically significant difference (p 0.05) between (1) the dry and moist conditions of Assure(tm) and Smartbond(R) (2) the 24 hour and 6 month time frame for all adhesives.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Light cured composite resin can be time consuming for bonding orthodontic brackets. A new Blue light diode laser may reduce curing times for composite resins. Hypothesis: The laser will achieve similar bond strengths in half the time and at greater distances as the LED. Methods: 90 extracted premolars will be bonded and cured using Laser and LED curing units at varying times, another 120 extracted premolars will be bonded and cured at varying distances. An Instron machine will be used to test shear bond strength. Results: The laser was not able to achieve similar bond strengths as the LED curing light in half of the curing time. At 5 seconds, the laser had 35% lower bond strengths but was still in the clinically acceptable range. The laser achieved similar bond strengths when the curing tip was at greater distances as when it was close to the bracket-adhesive-tooth interface.

This book was released on 2013 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the effect of light curing sources on shear bond strength and degree of conversion of orthodontic resin composite adhesive as function of type of curing unit and total energy, as well as evaluated the correlation between shear bond strength and degree of conversion. Curing units included in the study were plasma arc (PA), light emitting diode (LED) and quartz tungsten halogen (QTH) with 5k, 10k, or 15k mJ/cm2 of total energy delivered to the orthodontic adhesive by each unit type. Based on an analysis of variance (a =.05), there was no significant effect of type of curing source on shear bond strength; however, there was a significant effect of total energy, with shear bond strength increasing as energy increased across curing units. For degree of conversion there was a significant effect of curing unit with PA producing higher degree of conversion than LED or QTH, which were not significantly different from each other. There was also a significant effect of total energy on degree of conversion with a significant increase between 5k to 10k mJ/cm2. There was a positive moderate overall correlation between shear bond strength and degree of conversion. Results of this study suggest that the PA curing unit is more efficient at polymerization (degree of conversion) of orthodontic resin composite adhesive. However, there is no difference in shear bond strength produced when using PA, LED or QTH curing sources for orthodontic bracket bonding procedures when equal total energy is delivered to the adhesive.

This book was released on 2010 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose : The effect of L.E.D. Pro Seal on Shear-Peel Bond Strength of Orthodontic Brackets (SPBS) was evaluated. Assure and its effects on SPBS will be evaluated. Materials and Methods: One hundred extracted premolars were randomly assigned to one of four groups. Transbond XT Primer with APC II brackets was the control. Comparisons were made to Pro Seal and Assure as primers. After therrnocycling brackets were debonded with an Instron. Data analyzed with one-way ANOVA and Tukey-Kramer. Results: The SPBS of the control group was higher than all other groups. No significant difference was found between all other groups. Pro Seal group had lowest SPBS. Adding Assure did not significantly increase SPBS. Conclusion: The bond strength of the groups with L.E.D. Pro Seal were significantly lower than the control, they were within the clinical range. The addition of Assure did increase SPBS, but not significantly, and may be an unnecessary step.

Available in PDF, EPUB and Kindle. Book excerpt: The evolution of orthodontic materials in the past 5 decades has been a unique progress curve characterized by periods of intense activity with many developments followed by long quiescent intervals. An example of the delay in adopting the advances in dentistry might well be illustrated by the acid-etching technique, which was introduced in the mid 1950s1 and became universally accepted in the 1960s. It took more than a decade for this practice to become standard procedure in orthodontics on a large scale. Infact, orthodontic bonding has advanced more in last 10 years than previous 25. In the past decade, we have witnessed unprecedented progress in bonding to enamel with various materials techniques and auxiliaries involving glass ionomer bonding, self-etching primers, and new, powerful light-curing sources, along with self-ligating brackets and a different treatment concept, the Invisalign technique.
