Taurodontism and Periodontal Status
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.

Treatment and study plan
Primary outcomes
-
Periodontal status/ Probing Depth (PD)
Time frame: Baseline
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.
-
Periodontal Status/ Clinical Attachment Level (CAL)
Time frame: Baseline
Clinical attachment level (CAL) will be measured in millimeters at six sites per tooth and compared between participants with and without taurodontism.
-
Periodontal Status/ Bleeding on Probing (BOP)
Time frame: Baseline
Bleeding on probing will be recorded as the presence or absence of bleeding after periodontal probing and compared between participants with and without taurodontism.
-
Periodontal status/ Plaque Index (PI)
Time frame: Baseline
Plaque Index (PI) will be assessed to evaluate oral hygiene status and compared between participants with and without taurodontism.
-
Periodontal Status/ Gingival Index (GI)
Time frame: Baseline
Gingival Index (GI) will be used to evaluate gingival inflammation and compared between participants with and without taurodontism.
Secondary outcomes
-
Oral Health-Related Quality of Life (OHIP-14)
Time frame: Baseline
Oral health-related quality of life will be assessed using the Oral Health Impact Profile-14 (OHIP-14) questionnaire.
