Effect of nonsurgical periodontal therapy on thyroid stimulating hormone in hypothyroid patients with periodontal diseases.

Background: The endocrine and the immune system demonstrate a mutual relationship under pathophysiologic conditions. Thyroid hormone plays an important role in the regulation of normal growth and development. Although there is proven bidirectional influence of systemic diseases on periodontium, there are fewer studies on the effect of periodontal therapy on the hormone levels.

Comparison of salivary calcium level in smokers and non-smokers with chronic periodontitis, aggressive periodontitis, and healthy controls.

Objective: The purpose of this study was to compare salivary calcium (Ca) level in smokers and non-smokers with chronic periodontitis, aggressive periodontitis, and healthy controls.

Materials And Methods: 56 subjects were included in the study and were grouped as follows: 12 subjects who were periodontally healthy (Group I), 12 subjects having chronic periodontitis who were non-smokers (Group II), 12 non-smokers having aggressive periodontitis (Group III), 12 smokers with chronic periodontitis (Group IV), and 8 smokers with aggressive periodontitis (Group V). Clinical measurements and non-stimulated whole saliva samples were obtained and analyzed for Ca levels by ion-selective electrolyte analyzer.
