| Summary: | Aims and Objectives: To evaluate and compare the shear bond
strength of stainless steel brackets and ceramic brackets at
24h after etching the enamel with acidulated phosphate fluoride
gel (1.23% APF) at different proportions (40%,30%,20%)
incorporated in conventional etchant (37% phosphoric acid).
Materials and Methods: Eighty premolars (maxillary and
mandibular first and second premolars) extracted for orthodontic
purpose has been selected for the study and samples were
divided into 4 groups containing 10 teeth each. Comprised of
teeth etched Group 1 with 40% of APF gel etchant is Group 2
teeth etched with 30% of APF gel in Group 3 teeth etched with
20% of APF gel etchant and Group 4 teeth were etched with
conventional etchant (37% phosphoric acid).
Results: The experimental group of Acidulated Phosphate
Fluoride (APF) at different proportion (40%, 30%, 20%) incorporated with etchant application for 40s on the enamel surface
at 24h indicated that group 4 showed the higher bond strength
of all other remaining groups and the groups 1, 2 and 3
showed satisfactory bond strength. The statistical evaluation
also revealed that the bond strength of control group (37%
phosphoric acid) was greater than those of experimental
groups.
Conclusion: The present study results shows that the ceramic
brackets have higher bond strength than stainless steel brackets
(material wise). |
