Abstract: Introduction: Orthodontics, a dental specialty focused on correcting dental anomalies and malocclusions, frequently relies on materials such as orthophosphoric acid (H₃PO₄) for enamel etching during bracket bonding procedures. However, this acid may induce changes in salivary pH, potentially altering the oral microbiota and increasing the prevalence of mucosal lesions. Methods: A clinical and epidemiological study was conducted on 30 patients aged between 10 and 25 years, all undergoing fixed multibracket orthodontic therapy. Salivary pH variations were measured before and after the application of orthophosphoric acid to assess its impact. Results: The findings revealed a significant decrease in salivary pH following acid application, indicating a more acidic environment capable of affecting the oral flora. Discussion: These results highlight the influence of orthophosphoric acid on the oral ecosystem, emphasizing the need for preventive strategies to minimize adverse effects on the mucosa.
