About this study
Official title: Tooth Loss Rate and Its Associated Factors in Adult Population: a Retrospective Cross-sectional Study With up to 50 Years of Follow-up.
This study will evaluate, in an adult population (n=448) previously diagnosed with gingivitis and/ or periodontitis, the tooth loss rate and its potential associated factors such as diabetes, smoking, bruxism, cardiovascular diseases, and also the effect of supportive periodontal therapy on these factors, with an up to 50 years of follow-up period.
Significant results of the present study will help in the future reduction of tooth loss among periodontally involved patients.

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Tooth loss rate (time frame: From 10 up to 50 years). 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 29 Aug 2024.
