What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether the calcification stages of the lower second molar can reliably indicate skeletal maturity in Egyptian adolescents aged 9 to 18. Researchers will compare dental X-rays with cervical vertebrae maturation index from lateral cephalometric X-rays in 212 participants. The goal is to see if dental development can serve as a practical tool for assessing bone age without additional radiation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could provide a simpler way to assess bone age using dental X-rays, reducing the need for hand-wrist radiographs.
What could go wrong
This is an observational study, not a treatment trial. Results may only apply to the Egyptian population and need validation in other groups.
