A Study to Assess and Correlate Osteoporosis and Periodontitis in Selected Population of Maharashtra.

Background: Osteoporosis is a systemic bone disorder characterized by decreased bone mass and increased risk for fracture. It has been proposed as a possible risk factor for periodontal disease progression. Recent literature has shown periodontitis to be a risk indicator for osteoporosis, suggesting a possible two way relationship.

ABO blood groups and Rhesus factor: an exploring link to periodontal diseases.

Background: The presence or absence of blood group antigens has been associated with various diseases, with antigens also acting as receptors for infectious agents. Scanty literature is available in assessing the relative liability of blood group phenotypes to periodontal diseases. This research was conducted to determine the association of the ABO blood group and Rhesus (Rh) factor to periodontal diseases to assess whether they could be the predictors of periodontal diseases.
