About this study

Official title: Intra-oral Evaluation of Force Decay of Pigmented and Transparent Elastomeric Power Chains: A Randomized Clinical Trail.

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.

Read the 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.

Primary outcome

Evaluate the force decay of pigmented and transparent elastomeric power chains in a group of orthodontic patients
Time frame: Baseline and weekly for 6 weeks.
Measurement of the amount of force decay (in grams) for each elastomeric power chain sample at baseline and at 7 time intervals over 6 weeks using a digital force gauge.

1 secondary outcome

Correlation between force decay and associated variables (tooth movement, masticating side, beverage consumption, brushing frequency, oral hygiene, and khat chewing)
Time frame: At 6 weeks

Results and safety

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

Questions about this trial

What is this clinical trial studying?

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Yemen. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate the force decay of pigmented and transparent elastomeric power chains in a group of orthodontic patients (time frame: Baseline and weekly for 6 weeks.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07300371.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Dec 2025.
