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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers at Inonu University are studying three proteins, TBC1D15, Rab7, and Fis1, that help cells recycle damaged mitochondria. They will collect gum fluid from 72 adults with healthy gums, gingivitis, or periodontitis and measure the levels of these proteins. The goal is to see whether protein levels change as gum disease gets worse, which could hint at a role for mitochondrial health in the disease.

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 protein levels track with gum disease severity, this could point to new ways to detect or treat gum disease earlier.
What could go wrong
This small observational study measures proteins at one point in time, so it cannot prove that mitochondrial problems cause gum disease. The findings may not lead to a treatment.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adults aged 18 to 65 years attending the periodontology clinic were enrolled and classified into 3 groups based on clinical periodontal parameters and smoking status according to the 2017 World Workshop classification: periodontal health, gingivitis, and periodontitis (Stage III Grade B). Exclusion criteria included any systemic disease, regular medication use, pregnancy or lactation, periodontal treatment within the past 6 months, antibiotic use within the past 6 months, and presence of prosthetic restorations on the teeth to be sampled. A total of 72 participants (24 per group; 36 males, 36 females) were included.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Inclusion criteria for the Healthy Control group: * presence of ≥ 20 teeth in the mouth-probing pocket depth (PPD) ≤ 3 mm * the percentage of bleeding sites for the whole mouth \< 10%, on radiographic examination * a distance of ≤ 3 mm between the cemento-enamel junction and the alveolar bone crest in 95% of all teeth. Inclusion criteria for the Gingivitis group: * presence of ≥ 20 teeth in the mouth * PPD ≤ 3 mm, -% of bleeding sites for the whole mouth ≥ 10%, * on radiographic examination, a distance of ≤ 3 mm between the cemento-enamel junction and the alveolar bone crest in 95% of all teeth. Inclusion criteria for the Stage 3 Periodontitis group: * presence of ≥ 15 teeth in the mouth * more than 30% of teeth affected by periodontal disease * affected teeth exhibiting probing depths of 6 mm or more * clinical attachment loss (CAL) of ≥ 5 mm, * vertical bone loss of 3 mm or more * class 2 or 3 furcation involvement * radiographic evidence of alveolar bone loss extending to the middle third and beyond (33%) in the relevant teeth Exclusion Criteria: * presence of any systemic disease * regular use of any medication * pregnancy or lactation * periodontal treatment within the last 6 months * antibiotic use within the last 6 months * the presence of prosthetic restorations on the teeth to be sampled
