An observational study in Periodontitis and Bruxism, sponsored by Mustafa Kemal University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-29.
Sponsored by Mustafa Kemal University · Observational
This prospective observational cohort study evaluated changes in the trabecular bone structure around teeth after nonsurgical periodontal treatment in patients with periodontitis, with and without bruxism. Fractal dimension was measured on standardized periapical radiographs taken at baseline and six months after treatment. Clinical periodontal measurements were also recorded at both time points. The main objective was to determine whether changes in fractal dimension after periodontal treatment differed between patients with and without bruxism.
1,231 studies on the registry are indexed under Periodontitis; 295 are open to participants now.
This study's enrollment of 65 is below the median of 90 across 372 observational studies indexed under Periodontitis.

Adults with Stage II-III, Grade B periodontitis who presented to the Department of Periodontology, Faculty of Dentistry, Hatay Mustafa Kemal University and met the predefined eligibility criteria were enrolled. Participants were classified according to the presence or absence of probable bruxism and were prospectively followed for six months after nonsurgical periodontal treatment.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Patients with Stage II-III, Grade B periodontitis who met the predefined study criteria for bruxism and were followed for six months after nonsurgical periodontal treatment.
Other: Bruxism Status
Patients with Stage II-III, Grade B periodontitis who did not meet the predefined study criteria for bruxism and were followed for six months after nonsurgical periodontal treatment.
Participants were classified according to the presence or absence of probable bruxism based on self-reported information and clinical examination findings using predefined study criteria. Sleep and awake bruxism were not assessed separately, and no instrument-based assessment was performed. Bruxism status was observed and was not assigned by the investigators.
Change in Alveolar Trabecular Bone Fractal Dimension
Fractal dimension was calculated from standardized periapical radiographs of the mandibular first molar region using the box-counting method in ImageJ. The change in fractal dimension from baseline to six months after nonsurgical periodontal treatment was evaluated and compared between patients with and without bruxism.
Time frame: Baseline to 6 months
Change in Plaque Index
Plaque index was recorded at baseline and six months after nonsurgical periodontal treatment, and the change over time was evaluated.
Time frame: Baseline to 6 months
Change in Gingival Index
Gingival index was recorded at baseline and six months after nonsurgical periodontal treatment, and the change over time was evaluated.
Time frame: Baseline to 6 months
Change in Bleeding on Probing
Bleeding on probing was recorded as a percentage at baseline and six months after nonsurgical periodontal treatment, and the change over time was evaluated.
Time frame: Baseline to 6 months
Change in Probing Pocket Depth
Probing pocket depth was measured in millimeters at baseline and six months after nonsurgical periodontal treatment, and the change over time was evaluated.
Time frame: Baseline to 6 months
Change in Clinical Attachment Level
Clinical attachment level was measured in millimeters at baseline and six months after nonsurgical periodontal treatment, and the change over time was evaluated.
Time frame: Baseline to 6 months

Ran from May 2025 to primary completion in Apr 2026, 11 months.
Of 85 non-industry observational studies under Periodontitis, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 30. This study's 11 months is below that.
Counting every sponsor, half of 86 studies reached it within 13 months; a quarter within 7 and three quarters within 30.
