ABSTRACT: Gingival bleeding is the first clinical sign of periodontal disease. This clinical sign indicates the beginning of the destructive process involving the supporting tissues around the tooth or some serious systemic problems. There are various causes for gingival bleeding. The main factor responsible for gingival bleeding is the formation and accumulation of plaque due to improper oral hygiene. There are various systemic factors (Diabetes, hypertension, blood disorders, hormonal imbalances & nutritional deficiencies) and other local factors responsible for gingival bleeding. The examination of bleeding of gums is done by using a periodontal probe. The evaluation of the gingival health is assessed by calculating the number of bleeding sites which is recorded using the gingival bleeding index score. This condition can be controlled by following proper oral hygiene measures, regular dental check-ups and treating the root cause of the bleeding (both systemic and local factors).
