sIgA, peroxidase and collagenase in saliva of smokers aggressive periodontal patients.

Background: Tobacco smoking is strongly associated with destructive periodontal disease, alveolar bone loss and poor response to periodontal therapy. The aim of this study was to investigate the effect of smoking on antimicrobials and destructive proteins in the saliva of patients with generalized aggressive periodontal disease.

Material And Methods: The study group consisted of 55 adult subjects.

Cytological analysis of the periodontal pocket in patients with aggressive periodontitis and chronic periodontitis.

Background: Oral exfoliative cytology includes the study and interpretation of the features cells exfoliated from the oral mucosa. The aim of this study was to analyze cytological changes in the periodontal pocket of patients with different clinical stages of aggressive periodontitis (AP) and chronic periodontitis (CP).

Materials And Methods: Patients aged 24-54 years, of whom 41 were diagnosed with AP, 40 with CP, sub-classified as mild, moderate and severe periodontitis, and 40 healthy individuals who were the control group.

Histopathologic and histomorphometric studies and determination of IL-8 in patients with periodontal disease.

Background: Periodontitis is an inflammatory disease characterized by connective tissue breakdown and alveolar bone resorption.

Objective: The aim of this study was to make a quantitative evaluation of the gingival tissue components in biopsies from patients with different clinical states of periodontal disease and to determine the relationship between the presence of interleukin-8 and the tissue destruction.

Materials And Methods: The study group consisted of 33 biopsies from adult subjects.

Changes in saliva protein composition in patients with periodontal disease.

Periodontitis is a chronic inflammatory disease characterized by tissue destruction which is usually diagnosed through clinical and radiographic signs. The detection of changes in the chemical composition of saliva could be used to reflect gingivo-periodontal alterations. The aim of this study was to identify salivary parameters that could identify different stages of the periodontal disease.

Biochemical markers of the periodontal ligament.

For many years the diagnosis of Periodontal Disease has been based on clinical and radiographic methods. Other more recent methods have the objective of studying the inflammatory response of the host. That way, immunologic and biological methods determine the free mediators in the periodontal infection.

Salivary characteristics of diabetic children.

Salivary components may suffer variations that can be detected by chemical determinations. The aim of this work was to determine physical and biochemical characteristics of the saliva of a group of diabetic children compared to those of a control group. Relation to oral health indices was also determined.
