ABSTRACT
INTRODUCTION: The global COVID-19 pandemic has caused changes in the daily life of people, with a particularly relevant impact upon certain groups of individuals that have difficulties in facing stress. A study is made of the impact of the pandemic upon patients with burning mouth syndrome (BMS). MATERIAL AND METHODS: A total of 40 patients with BMS diagnosed in the Unit of Oral Medicine (University of Murcia, Spain) were included. In all cases the study comprised a standardized clinical interview by the same professional and an exploration of the oral cavity. The first visit took place before the pandemic and consisted of the evaluation of anxiety (Hospital and Anxiety Depression Scale [HADS]), the Pain Catastrophizing Scale (PCS), pain intensity (visual analog scale [VAS]) and sleep quality (Pittsburg Sleep Quality Index [PSQI]), while the second visit took place one and a half months after the start of lockdown due to the pandemic in Spain. RESULTS: The study sample consisted of 36 women (90%) and four men (10%) aged between 39 and s86 years. Statistically significant differences were recorded between the two visits in terms of anxiety (p < 0.001), sleep quality (p < 0.001) and pain intensity (p < 0.001). CONCLUSIONS: The appearance of the COVID-19 pandemic has triggered worsening of anxiety, sleep quality and pain intensity in patients with BMS.
