and carbonated drinks. These acids may also come from acidic medications such as ascorbic acid (vitamin C) or acetylsalicylic acid (Aspirin(r)) [2; 4; 6; 7; 8; 9; 16]. As a third source, unknown acids may come from idiopathic sources. In these cases, the clinical exploration, anamnesis, and complementary tests do not allow the etiology of the lesions to be clarified [4; 13]. For decades, dental erosion has remained a condition of minor interest for public and private clinicians, and for the scientific community [17]. However, during the past decade, a significant increase in the prevalence of erosion has been registered, especially among children and adolescents, which has led to a larger interest in the study and investigation of this condition by different sanitary disciplines, especially dentistry [1]. The World Health Organization (WHO) is the authority which addresses and coordinates all sanitary action that takes place in the United Nations [18]. It is its responsibility to schedule and coordinate every investigation on health, and to set the norms that must be followed by the public health institutions worldwide. In 2008, the WHO presented an Action Plan for the Global Strategy for the Prevention and Control of Noncommunicable Diseases with the objective of promoting actions to reduce the main risk factors of non-transmissible diseases such as dental erosion. In 2003, five years before the launch of the previously mentioned strategic plan [19], the WHO considered the promotion of oral health and analyzed the risk factors of dental diseases in its World Oral Health Report. Educating the population was established as the main strategy for the prevention and control of these diseases. Different strategies were proposed [20]:  
* Nutritional counseling covering both general aspects of health and nutrition and specific aspects about oral health. * Information about the benefits of reducing the intake of carbonated sweetened drinks since it is an important risk factor in the development of dental erosion. * Advising about the benefits of reducing the intake, the amount and the frequency of acidic and carbonated drinks, since it is the main risk factor in the development of dental erosion. At present, the world is facing important challenges related to nutrition, either by its deficit which causes hunger or nutritional deficiencies, or by its excess, causing overweight and obesity. The globalization of the markets and the economic development have led to rapid changes in diets and lifestyles, increasing the prevalence of chronic diseases such as obesity, diabetes, cardiovascular diseases, cancer and osteoporosis, and oral diseases such as caries, periodontal disease and dental erosion [20; 21]. The WHO created the International Statistical Classification of Diseases and Related Health Problems (ICD) in 1998 to enable the classification of diseases in order to keep a systematic recording system, allowing the interpretation and comparation of data about mortality and morbidity from different countries or regions and during different periods of time. The term \"dental erosion\" appeared for the first time in this classification in 2010, twelve years after its coining [22]. It is important to highlight that in the past decade, an upward trend in the number of studies about dental erosion has been observed, as shown in Figure 1. The figure represents the number of articles published about this topic from 1945 to the present. During the first decades, until around 1960, very few studies were conducted--less than 30 per year. During the 1990s, an increase in scientific production can be observed, with an average of 50-70 articles published per year. As previously stated, it was during the twenty-first century, as the prevalence of dental erosion was increasing, that researchers were motivated to increase the number of publications, reaching up to 250 per year in recent years.
