This book was released on 2011-10 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many studies have been done on the shear bond strength of brackets adhered to acid-etched enamel and so far, there is no study on shear bond strength of brackets adhere to laser-etched enamel in Iraq. So, this study is an attempt to compare the shear bond strength of brackets adhered to laser-etched enamel with that of brackets adhered to acid-etched enamel. The application of laser irradiation to etch dental enamel for direct bonding of orthodontic appliance has been studied. CO2 (Carbon Dioxide) laser are capable of producing surface irregularities in human enamel which resemble those resulting from etching of enamel with ortho-phosphoric acid. Whether laser conditioning improves the retention of composite resins to the same degree as conventional acid-etching techniques has been the subject of several investigations.

This book was released on 2012 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was carried out to evaluate and compare the shear bond strengths between the orthodontic bracket and acid etched enamel, enamel treated with self-etch primer and laser irradiated enamel and to analyze the interface of the enamel bracket bond.It will help students, teachers and othodontia practitioners as it deals with the most contemporarily used bonding techniques. The results indicate that the shear bond strength of all the three groups was clinically acceptable with no significant difference between them but more adhesive was left on enamel treated with acid and laser as compared to self-etch primer treated enamel.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to compare the shear bond strength of orthodontic brackets to enamel in four bonding protocols: SEP without prior pumicing (None), Pre-etch and SEP without prior pumicing (Pre-etch), control: SEP with prior pumicing (Pumice), and Pre-etch and SEP with prior pumicing (Both). 80 extracted bovine incisors were randomly divided into 4 groups of 20, and brackets were bonded under the different experimental conditions. Debonding force was measured with an Instron universal testing machine. A two-way ANOVA comparing the four groups indicated that there was a significant difference in debonding force (P = 0.001). The SEP without prior pumicing group (17.69 " 7.18 MPa) was statistically different from the SEP group with prior pumicing (25.82 " 6.84 MPa). There was no statistical difference found among the other groups. Differences in the Adhesive Remnant Index (ARI) were analyzed by chi-square. ARI scores differed significantly (P =0.0048).

This book was released on 2011-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-etching primers are the latest addition to the armamentarium of an orthodontist. Their main advantage is that they reduce the number of steps required in the bonding of orthodontic brackets. However, their low ph was a cause of concern. This book describes a study undertaken to see the effects of ph of self-etchant on shear bond strength of orthodontic brackets. These shear bond strengths were also compared to those obtained with a conventional 3-step bonding system. It was found that self-etching primers not only reduce the chair time in an orthodontist's clinic but also reduce the amount of enamel lost during etching. The bond strength achieved was less than that of the conventional bonding system but was acceptable for orthodontic purposes. Thus self-etching primers are an important and useful invention for simplifying the most critical step in orthodontic clinic- bonding.

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.
