The folds or pillars of tissue and muscle in the sides of the pharynx that demarcate the region of the tonsils. The areas can be seen at the back of the throat.
Fibrin
An insoluble protein formed during the clotting process that traps and enmeshes the red blood corpuscles to stop the flow of blood. A deficiency is found in haemophiliacs.
Fillings
Materials placed in the teeth to replace lost tooth substance. Various materials are used as fillings. Amalgam: [see amalgam] Composite: [see composite] Glass ionomer: [see glass ionomer] Cements: [see dental cements]
Fissure
A fold, groove or trough in the enamel of the tooth. This area is vulnerable to decay as it is difficult to clean. Sealants are used to prevent the area becoming decayed.
Fistula
A permanent hole or opening in tissue through which fluid can drain. The most common type of fistula can occur during the extraction of an upper molar where the roots are very close to the sinuses. If the lining of the sinus is breached an opening (fistula) connecting the mouth to the nasal airways can occur. If this is not treated, the tissues can heal and leave an opening through which food can leak into the nasal area.
