Effect of sodium fluoride mouthwash On tensile strength and percentage Elongation of elastomeric chains at Different intervals after activation: An in-vitro and in-vivo study

Abstract

Introduction: Elastomeric chains became widely known among orthodontists due to their ease of use, reduced chair-side time, low cost, and high flexibility. Elastomeric chains can be used to close spaces in extraction sites as well as to close generalized spacing. Because of their widespread use in orthodontics, it is critical for orthodontists to understand their tensile qualities when they are under stress. If their dimensions change quickly, such as within 24 hours of use, their efficiency in the retraction system will suffer. Patients undergoing fixed mechanotherapy are usually prescribed mouthwashes, in addition to tooth brushing and other interdental aids. Hence, the orthodontist must understand how fluoride-containing mouthwash affects the tensile properties of the elastomeric chains.

Hence, this study was conducted with the aim to determine the effect of 0.05 percent Sodium Fluoride mouthwash on the tensile strength and percentage elongation of elastomeric chains both in-vitro (i.e., exposed to air) and in-vivo (i.e., intraorally, in the mouth).
