Abstract
Many people sometimes experience pain when they inhale breath across the cingula, or sensitivity and/or pain when they eat ice cream, for example. In some cases, however, this can become seriously unpleasant. In those cases, one can speak of dentine hypersensitivity. In Europe, an average of 27% of the population suffers from this. Dentine hypersensitivity is characterised by a short, sharp pain reaction after a warm or cold sensation. The external sensation causes an accelerated or converse flow of fluid in the dentinal tubules that excites the extremities of the nerve cells, which results in the sensation pain. For the external sensation, it is necessary that the cingula are exposed and the dentinal tubules are open. Dentine hypersensitivity is diagnosed after other possibilities have been eliminated.
