Brief Summary
This study aimed to evaluate the amount of force decay in pigmented and transparent elastomeric power chains. The principal investigator measured the amount of force decay at 7 intervals using a calibrated Dentaurum force gauge. This study also assessed the associated variables that accelerate the force loss, such as brushing frequency, beverage consumption,mastication, Khat chewing, oral , and tooth movement, . The study outcomes provide evidence-based guidance for selecting elastomeric power chains in routine orthodontic practice.
