Availability of complete periodontal clinical records, including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), plaque index (PI), and gingival index (GI).
Who cannot join
- Poor-quality or nondiagnostic panoramic radiographs. Teeth with extensive caries or restorations that interfere with taurodontism assessment.

About this study
Official title: Evaluation of the Relationship Between Taurodontism and Periodontal Status: A Cross-Sectional Study
This retrospective cross-sectional observational study aims to evaluate the relationship between taurodontism and periodontal status. Clinical periodontal parameters and panoramic radiographs of systemically healthy adults will be retrospectively reviewed. Participants will be classified according to the presence or absence of taurodontism, and periodontal status will be assessed using clinical and radiographic findings. The study aims to determine whether taurodontism is associated with periodontal disease and periodontal health.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Taurodontism Group | Participants with at least one permanent molar diagnosed with taurodontism on panoramic radiographs according to the Shifman and Chanannel criteria. | |
| Control Group | Participants without radiographic evidence of taurodontism, matched to the taurodontism group and evaluated using the same clinical and radiographic periodontal parameters. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Periodontal status/ Probing Depth (PD)
Probing depth (PD) will be measured in millimeters at six sites per tooth using a periodontal probe and compared between participants with and without taurodontism.
Measured: Baseline
Periodontal Status/ Clinical Attachment Level (CAL)
Clinical attachment level (CAL) will be measured in millimeters at six sites per tooth and compared between participants with and without taurodontism.
Measured: Baseline
Periodontal Status/ Bleeding on Probing (BOP)
Bleeding on probing will be recorded as the presence or absence of bleeding after periodontal probing and compared between participants with and without taurodontism.
Measured: Baseline
Periodontal status/ Plaque Index (PI)
Plaque Index (PI) will be assessed to evaluate oral hygiene status and compared between participants with and without taurodontism.
Measured: Baseline
Periodontal Status/ Gingival Index (GI)
Gingival Index (GI) will be used to evaluate gingival inflammation and compared between participants with and without taurodontism.
Measured: Baseline
Secondary outcomes (1)
Oral Health-Related Quality of Life (OHIP-14)
Oral health-related quality of life will be assessed using the Oral Health Impact Profile-14 (OHIP-14) questionnaire.
Measured: Baseline

Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). 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?
This study is still under way. Results are not available in the source record yet.
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?
Periodontal status/ Probing Depth (PD) (time frame: Baseline). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 14 Jul 2026.
