Comparison of Salivary TIMP‐1 Levels in Periodontally Involved and Healthy Controls and the Response to Nonsurgical Periodontal Therapy

International Journal of Chronic Diseases, Volume 2014, Issue 1, 2014., 2014
Background. Periodontal disease is a chronic inflammatory condition affecting the supporting structures of the dentition. Periodontal destruction is an outcome of the imbalance between matrix metalloproteinases and tissue inhibitors of matrix metalloproteinases (TIMPs). We wanted to prove the hypothesis that salivary TIPM‐1 level will vary in different
