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.

Detailed description

The study was a split-mouth randomized clinical trial. Four colors (pink, blue, black, and grey) and transparent elastomeric power chains from 3 different companies (American Orthodontic, SIA, and Matt) were evaluated. A total of 96 participants were recruited, and 192 elastomeric power chains were stretched between the canine bracket hook and the molar band hook throughout the study period. The delivered force of elastomeric power chains was assessed and compared among each other using a calibrated Dentarum force gauge over 6-week intervals (baseline, 24 hours, first week, second week, third week, fourth week, fifth week, and sixth week). To further investigate factors influencing force decay (FD), data on tooth movement, mastication side, beverage consumption, brushing frequency, oral hygiene status, and khat chewing were collected using a structured questionnaire to assess their potential impact.
