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.

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.

Summary

This study looks at whether a rare tooth condition called taurodontism, where teeth have enlarged pulp chambers, is linked to gum disease. Researchers will review dental records and X-rays from healthy adults to compare gum health between those with and without taurodontism. The goal is to understand if this tooth shape is a risk factor for periodontal problems.

Who can take part

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

Who is studied

The study population consists of systemically healthy adults aged 18-65 years who attended the Faculty of Dentistry at Recep Tayyip Erdoğan University between January 2019 and May 2026. Participants have diagnostic-quality panoramic radiographs, complete periodontal clinical records, and at least 20 natural teeth with no missing premolars or molars. Eligible participants are classified into taurodontism and control groups based on radiographic findings.

Inclusion Criteria: Adults aged 18 to 65 years. Systemically healthy individuals. Availability of a diagnostic-quality panoramic radiograph. Presence of at least 20 natural teeth. No missing premolar or molar teeth.
