Effects of oral deposits in the patient mouth

Deposits are organic and inorganic substances that cover the enamel, gum, cementum of the teeth, and appliances  in the mouth. Most of these deposits are unwanted, harmful and toxic substances or debris.
These deposits are, but not limited to :
      - Food debris .
      - Material alba.
      - Dental plaque.
      - Dental calculus.
      - Dental stain.

Dental stain :

   It is the most common dental procedure done in dental clinic. It involve the discoloration of the teeth due to intake of pigmented substances that can stain teeth. They are often the results of pigmentation of food or chemical agent's. Dental stain may lead to tissue irritation by creating a rough tooth surface, which contributes to plaque accumulation.
  Food debris and dental stainschool create a favourable environment for plaque accumulation.
Plaque is the local initiating factors since it initiates and causes gum inflammations when it accumulates on the teeth adjacent to the gum.Therefore if plaque must be present for calculus to form, controlling calculus deposition begins with plaque control. The primary destructive action of calculus is that it acts as a holding mechanism for plaque.The underlying calculus acts as a nidus for the accumulation of the surface plaque and keeps the plaque in direct contact with the tissues. Calculus may also act as a mechanical irritant to the gingivitis and periodontal tissues.
   However, it is important to know that these deposits, if allowed to remain in the mouth without constant removal,  can cause oral disease. Such as ; mouth odour;  dryness of the mouth ( xerostomia ).
Although,  the dangerous effects of oral deposits on the general body system is stated that dental plaque,  food debris, and material alba are the causes of dental caries and periodontal diseases   and their consequent systemic infections.

These systemic infections include :

    ( a). Septicaemia: This is the presence and multiplication of bacteria in the blood stream. There are different barriers in the mouth that prevent the entry of bacteria plaque into the blood stream.
These barrier systemic include physical and immunological barriers, but when the normal body system state of equilibrium is disturbed by hypoxia,  trauma, poor oral hygiene, periodontal diseases, abscess, e.t.c, bacteria propagate and cause infections.
   (  b). Endocarditis: This is the inflammation of the endocarditis ( the inner membrane of the heart ), particularly of the heart valves.
Endocarditis often occurso due to infection with bacteria, which maybe introduced into the blood stream. Poor oral health, tooth extraction,   or vigorous use of a toothbrush particularly when there is periodontal infection which promotes introduction of bacteria into the blood stream. Thus, the main predispose factors are bacteriaemia, Septicaemia and pyaemia.
   ( c). Cardiovascular diseases : These are diseases of the heart, blood vessels, and blood circulation. Periodontal infections are capable of predisposing individual to cardiovascular diseases. Oral bacteria such as Streptococcus sangius and ponlayromonas gingivitis induce platelet aggression,  which can lead to thrombosis formation. When an antibody reaction to periodontal bacteria is induce , it localized in the heart and triggers complement activation. This may results to heart failure.
  (  d). Low birth weight: Research studies have shown that expected mother's with very poor oral health are prone to have babies weighing less than 2.4kg at birth. This could be due to multiplication and migration of bacteria as a result of frequent hormonal changes that occur during pregnancy.
