Effects of the COVID-19 pandemic on orthodontic care in Finland

OBJECTIVES: To investigate the measures that were taken to limit the risk of COVID-19 contagion, how the risk of adverse effects on patient treatment outcomes was mitigated in orthodontic practices in Finland during the COVID-19 pandemic, and how these measures affected the course of orthodontic treatment. MATERIALS AND METHODS: = 361). An additional inquiry was sent to the chief dental officers of 15 health centers. RESULTS: A total of 99 clinically active members (39.8%) responded to the questionnaire. Of them, 97.0% had made changes in their practices, e.g. using additional protective gear such as visors (82.8%), incorporating preoperative mouthwashes (70.7%), and limiting the use of turbines (68.7%) and ultrasonics (47.5%). Two in three respondents reported temporary lockdowns (mean 1.9 months, range 0.3-5.0 months), during which some occlusions slightly regressed (30.2%) and some relapsed to a previous stage of treatment (9.5%). During this study, 59.6% of respondents reported that some treatments were still behind schedule. One in three respondents had used teleorthodontics because of the pandemic. CONCLUSIONS: Preventive measures and changes in treatment procedures were implemented according to the local COVID-19 situation. Some treatments were prolonged, e.g. because of lockdowns or patient's fear of contracting COVID-19 whilst receiving treatment. New methods like teleorthodontics were introduced for coping with the increased workload.
