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 evaluated the shear bond strength of zirconia bonded to dentin specimens using a self etch dual cure resin cement after various surface treatments of zirconia. Twenty zirconia rods (3 9 2.5 mm) were prepared from zirconia blocks and assigned into 5 groups for the following surface treatments. (1) Group I: Control (C) no treatment (2) Group II: airborne-particle abrasion (APA),(3) Group III: hydrofluoric acid etching (HF), (4) Group IV: hydrofluoric acid etching followed by silanation (HF/S), and (5) Group V: application of zirconia primer(Z). Dentin Specimens were prepared from extracted molars stored in 0.5% chloramine-T. Zirconia rods were bonded to dentin using resin cement (Multilink Speed),then light polymerized. The specimens tested for failure were tested using the notched shear bond test method in a universal loading apparatus. One way ANOVA followed by Tukey HSD for cell means were used to analyze the data(=0.05). The highest values were obtained with group V (Z) (8.66 MPa) followed by group II (APA) (6.71 MPa), and group IV (HF/S) (4.41 MPa). The least values were obtained for group III (HF) (3.88 MPa) with no significant difference (P value 0.53) between group.
One of the goals of endodontic treatment is the complete debridement of the root canal system. Mechanical cleaning can greatly reduce the number of microorganisms but not completely eliminating them. Therefore, there is a need for an irrigant to enhance debridement. Sodium hypochlorite is still the most widely used irrigation solution in endodontics. However, many new irrigants have been introduced, MTAD is one of them. It is a mixture of tetracycline isomer, an acid and a detergent. MTAD is capable of removing the smear layer without causing excessive erosion and it has an antibacterial action against E. faecalis. With the more interest in resin-based obturation materials, it has been important to study the effect of the used irrigants on the adhesion of those materials to dentine. As MTAD is not a single component it is wise to study its effect on the adhesion of a self-etch resin-based sealer (Epiphany SE) to dentine.
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.
