U.S., July 24 -- ClinicalTrials.gov registry received information related to the study (NCT07721428) titled 'Salivary Angiotensin-Converting Enzyme and Periodontal Disease in Cardiovascular Disease' on July 07.

Brief Summary: The goal of this observational study is to learn whether the renin-angiotensin system, measured by angiotensin-converting enzyme (ACE) and angiotensin-converting enzyme 2 (ACE2) in saliva and blood, is associated with periodontal disease severity in adults undergoing cardiovascular evaluation.

The main questions it aims to answer are:

* Are salivary and blood ACE and ACE2 levels different according to periodontal disease severity?

* Do salivary ACE and ACE2 levels reflect the corresponding blood levels?

* Are ACE ...
