Comparative Evaluation of Shear Bond Strength of Flowable Composite Bonded to Teeth Enamel with Laser Surface Treatment

The aim of this study is to assess the shear security quality of two intra oral clay fix frameworks on metal substrate and fired substrate and to contrast among gatherings with evaluate a superior earthenware fix framework after corrosive scratching and laser surface treatment. Therefore, 40 Nickel chromium and 40 feldspathic ceramic specimens were fabricated and divided into two main groups which were further subdivided into four subgroups based on the repair systems used and surface treatments, which had ten specimens each. Hydrofluoric acid and Erbium-doped Yttrium aluminum garnet laser were used as surface treatments and two intra oral repair systems used were Bisco and Angelus. Bonded specimens were stored in distilled water for 24 hours before being thermocycled at 5°C to 55°C for 300 cycles with a 30-second dwell time. The specimens were stored for an additional 7 days before being subjected to shear force in a universal testing machine with a 10KN load cell at a crosshead speed of 0.5 mm/min. The bond strength values obtained were recorded in MPa and analyzed using independent t test. The outcomes indicate that the shear bond strength values obtained were highly significant for Bisco when compared to Angelus for both the metal and ceramic substrates. Similarly, after acid etching and laser surface treatment, Bisco proved to be better. At the end, Bisco repair system had significantly higher shear bond strength values when compared to Angelus. Hence it is the preferred choice for intraoral repair of fractured metal ceramic restorations. Er: YAG laser surface treatment is the recommended surface treatment for intraoral repair.

ABSTRACT Aim To evaluate and compare shear bond strength (SBS) and debonding characters of the Transbond XT (BisGMA-based composite), Esthet-X flow (flowable composite), Filtek Z-350 (flowable composite). Materials and methods A total of 90 human premolars were divided into group I, Transbond XT (n = 30); group II, Esthet-X flow (n = 30) and group III, Filtek Z-350 (n = 30), the preadjusted edgewise stainless steel premolar brackets were bonded to evaluate the shear bond and debonding properties. Results The results of the statistical analysis comparing the three groups indicated no statistically significant differences between the groups. In general, the SBS with groups I and III exhibited similar bond strength with 11.58 ± 1.3 MPa and 11.07 ± 1.0 MPa respectively. Groups III exhibited least bond strength of 10.7 ± 2 MPa. In modified adhesive remnant index (ARI) the majority of bond failures occurred at enamel-adhesive interface or cohesive type failure in all the three groups. Groups II and III showed increased frequency of score 2, 4 and 5 compared to group I which showed increased frequency of score 0 and 1. Conclusion When considering the SBS and ARI scores obtained, flowable composites can be effectively applied to orthodontic bracket bonding.
