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 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).

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: AIM: 1. To determine in vitro bond strength of metal and ceramic orthodontic brackets when using etch and separate primer, or self-etching primer (SEP) 2. To assess remaining adhesive following removal of orthodontic bracket METHOD: 180 previously extracted teeth were randomly allocated to one of six test groups. Each was subjected to either separate etch and primer or SEP and then bonded with an orthodontic bracket. These were metal (3M Unitek Victory), metal reinforced ceramic (3M Unitek Clarity) and poly-crystalline ceramic (3M Unitek Transcend). Samples were stored at 37 degrees C for 24 hours. Each bracket was debonded using shear force applied by the Instron Universal testing machine. Samples were examined under x10 light microscopy and allocated an Adhesive Remnant Index (ARI) score. RESULTS: Variation in shear bond strength (SBS) was seen across all groups. Lowest SBS was recorded with Victory series brackets bonded with SEP (7.08 MPa) and the highest was with Clarity series brackets bonded with separate etch and primer (15.96 MPa). Pooled data showed significantly higher SBS with separate etch and primer than SEP (T=2.83, p

Available in PDF, EPUB and Kindle. Book excerpt: Purpose: To evaluate the in vitro shear bond strength (SBS) of orthodontic attachments using 2 self-etching primers (SEP): iBOND and G-Bond. Methods: 180 molars were randomly divided into 12 groups. Teeth were bonded with a stainless steel button using Transbond XT composite. The bonding agents were iBOND, G-Bond, Transbond Plus SEP and Transbond XT primer (control). SBS's immediately, 24hours and 3months were measured with their Adhesive Remnant Index (ARI). Results: Transbond XT primer (11.22MPa) had a significantly higher immediate SBS than Transbond Plus SEP (5.32MPa), iBOND (6.69MPa) and G-Bond (8.30MPa). 24 hours, Transbond XT primer (16.65MPa) and Transbond Plus SEP (13.20MPa) had a significant increase in their SBS. No difference was observed at 3 months. ARI were significantly different between the groups at all time points. Conclusions: iBOND and G-Bond yielded sufficient SBS's over the three time points that may be sufficient to withstand occlusal and light archwire forces.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the current study was to develop a bonding method that can achieve clinically acceptable bond strength values while leaving a minimum amount of adhesive on the tooth surface during the debonding process. One hundred teeth were randomly assigned into groups. Five different enamel surface preparation protocols were tested (N = 20, each): Conventional acid etch, standard SEP, SEP applied with a light brush stroke (altered SEP 1), SEP applied directly to the composite of pre-coated bracket (altered SEP 2), and Primer Only groups. Brackets were debonded using an Instron universal testing machine (Instron, Canton, MA) in shear mode and the mean shear bond strength values were calculated. In addition, enamel surfaces were examined under light microscope to determine the location of failure using ARI. The Primer Only group had significantly lower mean shear strength (0.14 MPa, P0.05) than the conventional acid etch (13.81 MPa), standard SEP (12.10 MPa), altered SEP 1 (10.80 MPa), and altered SEP 2 (11.48 MPa) groups. The conventional acid etch, standard SEP, altered SEP 1 and altered SEP 2 groups were not significantly different from each other (p0.05). With respect to ARI values, there was a significant difference among these four groups. 85% of samples in the altered SEP 2 group had 10% or less composite resin left on their surfaces. This group had also a mean shear bond strength value of 11.43 MPa, significantly above the minimal strength needed for orthodontic attachment bonding, and the lowest ARI values overall. Therefore, application of SEP directly to the composite resin of the pre-coated brackets may be an ideal bonding method by providing adequate bond strength and leaving a minimum amount of composite resin on the tooth surface during debonding. It should be kept in mind that future in-vivo studies would be needed to confirm the findings obtained from the current in-vitro study.
