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.

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 2009 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: In an attempt to save chair time during bonding, self-etching primers are used along with metal brackets that are precoated with adhesive material. Fluoride releasing sealants has also been used commonly to prevent decalcification during orthodontic treatment. The purpose of this study was to compare the shear bond strength (SBS) of APC precoated brackets bonded with two different self-etching primers: Transbond Plus self-etch primer (TPSEP) and Reliance self-etch primer. This study also evaluated the effect of combining TPSEP or the Reliance SEP with LED Pro Seal, a fluoride releasing sealant for the enamel surface. Each of the self-etching primers (SEPs) and the combination of SEP combined LED Pro Seal were evaluated for shear bond strength after 24 hours of storage and thermocycling with 1 week of storage, in order to simulate some of the temperature changes in the oral cavity.^Materials and Methods: One hundred and twelve teeth were randomly divided into eight groups as follows: Group 1: Transbond Plus self-etch primer (TPSEP), Group 2: Reliance self-etch primer (Reliance), Group 3: TPSEP and LED Pro Seal, Group 4: Reliance and LED Pro Seal, Group 5: TPSEP with thermocycling, Group 6: Reliance with thermocycling, Group 7: TPSEP and LED Pro Seal with thermocycling, Group 8: Reliance and LED Pro Seal with thermocycling. An occlusogingival load was applied to the brackets producing a shear force at the bracket-tooth interface utilizing a Universal Testing Machine. Results: Significant differences in shear bond strengths among the groups containing the TPSEP or Reliance SEP, were detected by two-way ANOVA (p = 0.018). The results of the Newman-Keul's test that compared the test groups at 24 hours show that the shear bond strength of Reliance SEP (3.98 MPa " 1.30) was not statistically different from TPSEP (4.25 MPa " 1.16).^When each of the SEP is combined with the Pro Seal, a statistical difference in shear bond strength is detected between TPSEP (6.01 MPa " 3.05) and Reliance SEP (3.76 MPa " 1.52). Reliance SEP used alone vs. Reliance SEP combined with Pro Seal did not show any statistical difference in shear bond strength. However, when TPSEP was compared to TPSEP combined with Pro Seal, it showed a statistical difference in shear bond strength. Nonetheless, a two-way ANOVA did not detect any statistically significant interaction between the SEPs and the Pro Seal (p = 0.058). None of the groups showed statistically significant differences in shear bond strength when compared at the one week group. Conclusion: The newly introduced Reliance SEP provides similar shear bond strengths to Transbond Plus SEP. Reliance SEP with LED Pro Seal and Transbond Plus SEP with LED Pro Seal both provide adequate shear bond strengths.^Both SEPs used alone or with LED Pro Seal maintained its bond strength after thermocycling. LED Pro Seal is demonstrated to have good bond strength to enamel and can withstand the oral environment.

This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To compare the mean bond strengths and mode of bond failure, in vitro, of five bonding systems (MIP 1, Plastic Conditioner 2, Assure 2, Scotchbond 3, and Transbond XT 1), when bonding an orthodontic bracket to an artificially-aged composite resin restoration, with and without mechanical surface preparation with a diamond bur. Methods: Class V buccal composite resin restorations were prepared in 240 upper right central incisor dentoform teeth. The restorations were artificially age d for 35 days, bonded with metal brackets, stored in distilled water at 37°C for 30 days, thermocycled for 500 cycles, and subsequently debonded with an Instron universal testing machine. Results: The mean bond strengths for Transbond, MIP, Plastic Conditioner, Assure, and Scotchbond groups were 12.1, 12.3, 13.3, 17.2, and 17.7 MPa respectively. The mean bond strengths for Transbond+Diamond, MIP+Diamond, Plastic Conditioner+Diamond, Assure+Diamond, and Scotchbond+Diamond groups were 18.5, 16.4, 19.1, 19.5, and 20.7 MPa respectively. ANOVA revealed a statistically significant diffe rence (P d"0.05) among the groups. Conclusions: Mechanically roughening the surface of a composite resin restoration with a diamond bur, provided significantly greater bond strengths, regardless of the bonding resin used. However, Assure and Scotchbond, without diamond bur preparation, provided similar bond strengths to Transbond, MIP and Plastic Conditioner, with diamond bur preparation. 1. 3M Unitek, Monrovia CA 2.
