## 4 Discussion  
There is a consensus in the scientific community regarding the increase in the prevalence of dental erosion as a result of the frequent intake of acidic foods and beverages such as juices and soft drinks [15; 16; 17]. In recent investigations, a high prevalence of lesions that affect enamel and dentin can be observed with percentages that vary between 30 and 90%, while lesions that affect the pulp are scarce. Thus, the initiation and progression of enamel demineralization caused by the consumption of acidic beverages is a multifactorial process that depends on the pH and acid content of the beverage, as well as intraoral pH changes [39; 54; 55]. In most articles, closed questionnaires on dietary habits were used in order to collect data from patients [33; 48]. This methodology allows us to assess the risk of dental erosion based on dietary and behavioral factors, preventing the patient from forgetting or not mentioning certain aspects because they are not considered dangerous when in fact they are likely to cause dental erosion [56]. Some studies reviewed [40; 48] show that the correlation between the consumption of solid foods and acidic liquids and dental erosion was confirmed, making it necessary to focus on the prevention of the disease, especially on the modification of their consumption. [PERSON] et al. [42] investigated the frequency of intake of different drinks, and noticed a positive association between the prevalence of dental erosion and the consumption of soft drinks, isotonic drinks and fruit juices, concluding that the participants with a high consumption of said drinks presented more serious dental erosion compared to those with a lower intake [57]. In contrast, [PERSON] [37], [PERSON] [41], [PERSON] [46], and [PERSON] [51], concluded that there was no relationship between erosion and social class, or erosion and oral hygiene practices. In the same vein, [PERSON] [44], states that there is no association between race or ethnicity and dental erosion. When analyzing dairy products and tea in the present work, authors such as [PERSON] [32], and [PERSON], [PERSON] [44], observed a low prevalence of dental erosion in patients who consume these beverages, which indicates the protective nature of dairy drinks (milk, shakes and yogurts) and tea against the development of erosive lesions. [PERSON], [PERSON] [45], studied the frequency of consumption of acidic fresh fruits and observed a positive correlation between the consumption of apples, oranges, bananas and grapes and the development of erosive lesions. [PERSON], [PERSON] [43], found that certain dietary factors such as canned juices, raw mango, gooseberry, tamarind, honey, buttermilk, and other beverages showed a significant correlation with dental erosion. Most studies are carried out on adolescents because they are mature enough to perceive any change in taste between different drinks using a simple scoring method. They have a greater understanding of the questionnaires and offer greater collaboration than younger children. It should be highlighted that [PERSON] [40], affirms that at an older age, the erosive prevalence increases. Therefore, it must be diagnosed in order to provide the appropriate preventive measures. Thus, and as stated by [PERSON] [28], [PERSON] [39], and [PERSON] [31], educational programs for the community are necessary in order to implement early preventive measures [58]. [PERSON] et al. [39], advocate the use of fortified beverages (calcium-modified mixed fruit juices) that could be a good source of calcium for any population not able to consume milk and dairy products due to allergies or lactose intolerance. These fortified food products are called \"functional foods\" and are believed to address the traditional division between the pharmaceutical and food sectors. Further research is needed to critically assess the safety of such food products, especially with regard to oral health.
