Actual (reported)Periodontal disease is a chronic condition affecting the teeth and surrounding support structures, characterized by tooth loss and alveolar bone loss. Sanative therapy (ST) is the gold standard non-surgical treatment for periodontal disease and involves mechanically removing the subgingival bacteria from the periodontal pockets. Regular periodontal maintenance appointments are needed to maintain periodontal health after ST. Moreover, the periodontal health of individuals not requiring ST is also dependent on regular hygiene appointments. Due to Ontario's March 2020 COVID-19-related clinic closure for approximately 3 months along with a reduced numbers of appointments available due to guidelines of professional bodies and public health beyond this period of time, many appointments were considerably delayed or cancelled. The effects of this disruption to periodontal health in male and female patients who have undergone ST and continue with maintenance appointments or who attend for regular hygiene appointments have not yet been investigated.
