Sumario:BACKGROUND: The objective of this study was to investigate the impact of the COVID-19 pandemic on the prevalence and persistence of white spot lesions (WSLs) among patients treated with traditional braces. METHODS: A group of 434 consecutively finished cases who had pretreatment and post-treatment digital photographs taken were included in this study. Each set of photographs was evaluated by two investigators to determine prepandemic and postlockdown WSLs, in addition to changes in oral hygiene (OH) and other risk factors. RESULTS: There was a statistically significant difference in the development of WSLs pre–COVID-19 lockdown (PRL) versus post–COVID-19 lockdown (POL) (P < 0.001). The overall prevalence for the development of WSLs increased to 52.8% POL. For patients with good pretreatment OH, the risk of developing WSLs POL (42.0%) was two times greater than the rate in PRL (20.1%). For patients whose OH worsened during treatment, 81.2% of POL patients developed WSL compared with 69.6% of PRL patients. The incidence of WSLs was statistically greater in the maxillary anterior region POL than PRL, whereas the incidence in the mandibular anterior region did not reach statistical significance. The distribution of WSLs was greater POL for each tooth irrespective of the arch. CONCLUSIONS: Because of the COVID-19 pandemic, the prevalence of visible WSLs increased from 29.5% to 52.8%. Patients whose hygiene worsened during orthodontic treatment are at an increased risk of developing WSLs.
