Patients suffering from acid reflux due to endogenous causes are often affected by gastroesophageal reflux disease which, in the oral environment, causes lingual and palatal enamel erosion. As enamel does not have the intrinsic ability to repair itself, the application of alloplastic materials, such as toothpastes is suggestable. The aim of this “in vitro” study was to compare the effectiveness of two different toothpastes in preventing erosion due to gastroesophageal reflux disease. Six tooth elements from bovine jaws were prepared using a high-speed diamond bur and water irrigation. Acid attack simulation was carried out using a 15% HCl hydrochloric acid solution. After that, two different toothpastes with or without fluoride, were brushed at the sample surface using an electric toothbrush at standard position and force. SEM and profilometer analysis were performed. Statistically significant difference was found in average tooth surface roughness after using toothpaste with or without fluoride after the acid attack, as the former offered a greater remineralization. No difference was found in long-term prevention. Fluoridated toothpastes offer a greater degree of remineralization at a first acid attack, however, there is no difference in long-term prevention independently from the toothpaste type.
