The submitted rewiew presents a relationship between gastroesophageal reflux disease ( GERD) and oral health. The main affection in the mouth is a dental erosion. Dental erosion is defined as the progressive loss of hard dental tissues caused by a chemical process not involving bacterial action. Important by loss of tooth surface is also salivary production and buffering capacity. We modified the Eccles-Jenkins tooth wear index with fillings and prosthetics restorationes.

        Key words: gastroesophageal reflex disease (GERD) - dental erosion - normál and stimulated salivary flow rate - buffering capacity
