Biocorrosion as Na Etiological Factor of Non-Carious Lesions: A Literature Review

Abstract

Aim: The present study aimed to carry out a literature review about biocorrosion as an etiological factor of non-carious lesions and dentin hypersensitivity. Method: The bibliographic search was performed in the PubMed and Virtual Health Library (VHL)databases, selecting articles published from 2015 to 2020, available in full text, in Portuguese and English, and related to the proposed theme. Results: In the studies included, it was observed that substances with low pH, high titratable acidity, some lifestyles, and occupational habits are factors that can directly interfere with dental demineralization. As a consequence of this process, non-carious lesions and dental hypersensitivity have increased their incidence. Conclusion: The main sources of acids that attack dental structure are food and beverages and endogenous acids of gastric content. Thus, it must be considered themultifactorial character of this process and the association with other etiological factors, such as tension and friction in the development of non-carious lesions, aiming to restore oral health to the patient.

Addition of substances to reduce the erosive potential of acidic beverages to tooth enamel: A scoping review

“…In addition, the individual's biological factors, such as saliva composition, dental anatomy, occlusion pattern and the relationship of the teeth with the soft tissues of the mouth, are important factors for the patient to develop erosive lesions. 5,7,8 The pH also corroborates this process since the dental enamel can be dissolved at a pH below 5.5 and the dentin at a pH below 6.5. 9 Still, it is important not to judge the erosive potential of beverages and foods only by their pH, for there is no "critical pH" related to erosion.…”

“…Extrinsic causes are related to the form and frequency of consumption of foods and beverages with a high acid content and some drugs. In addition, the individual's biological factors, such as saliva composition, dental anatomy, occlusion pattern and the relationship of the teeth with the soft tissues of the mouth, are important factors for the patient to develop erosive lesions 5,7,8 . The pH also corroborates this process since the dental enamel can be dissolved at a pH below 5.5 and the dentin at a pH below 6.5 9 .…”

“…Non‐carious lesions can be classified according to their aetiology into attrition, abfraction, abrasion and erosion, most of which result from a combination of factors 3 . Acids mainly cause dental erosion without the involvement of microorganisms 4,5 . Depending on the acid source, the erosion can be distinguished into extrinsic, usually caused by acid foods and beverages, and intrinsic, caused by endogenous acid.…”

“…3 Acids mainly cause dental erosion without the involvement of microorganisms. 4,5 Depending on the acid source, the erosion can be distinguished into extrinsic, usually caused by acid foods and beverages, and intrinsic, caused by endogenous acid. Intrinsic erosion by endogenous acids is caused by contact of the acidic gastric fluid with the oral cavity, for example, in patients with gastrointestinal reflux disease and patients suffering from bulimia due to frequency of vomiting or alcohol abuse.…”
