The Effect of Immersion Time in Three Kinds of Carbonated Beverages on Orthodontic Elastic Latex’s Tensile Strength (In Vitro)

Abstract

<p class="AbstractContent"><strong>Objective</strong>: To study the effects of immersion time in three kinds of carbonated beverages on orthodontic elastic latex’s tensile strength</p><p class="AbstractContent"><strong>Methods</strong>: Subjects consist of 32 specimens orthodontic elastic latex ¼" and 4.5 oz of power, divided into 8 groups (IA, IB, IC, ID, IIA, IIB, IIC, and IID). Each group are immersed in artificial saliva (pH7) and stored in incubator (37 °C) for 24hrs for group I and 48hrs for group II. Each treatment groups will be immersed in three different carbonated beverages for 90s per day. Elastics being measured its tensile strength for group I at 24th hour, and 48th hour for group II using tension gauge. The data was tested with two way anova and post hoc Tukey.</p><p class="AbstractContent"><strong>Results:</strong> The result shows immersion time decreases elastic latex’s tensile strength (<em>p</em> < 0.05), and carbonated beverages affect elastic latex’s tensile strength (<em>p</em> < 0.05).</p><p class="AbstractContent"><strong>Conclusion:</strong> (1) There is a difference of orthodontic elastic latex tensile strength in the immersion in carbonated beverages for 24 and 48 hours, (2) there is a difference of elastic latex tensile strength orthodontic in the immersion in three kinds of carbonated beverages, and (3) there is interaction between immersion time in carbonated beverages and carbonated beverage brands</p>
