ABSTRACT
COVID-19 pandemic had several consequences including reduced access to public health care service that led to significant delays in screenings, diagnosis, and treatments. Peripheral giant cell granuloma (PGCG) is a benign exophytic lesion of reactive nature, affecting gingiva and alveolar ridge. Recent studies report its highest prevalence in 5th-6th decade of age, occurring mainly in mandible with an average size of 1.3-1.7 cm. We aimed to show the impact of pandemic on diagnosis delay in a patient with peripheral giant cell granuloma that reached unusual dimensions. ACaucasian 61-year-old male referred to our observation for the presence of an exophytic lesion on edentulous alveolar crest of the mandible. He was an edentulous patient, that developed a lesion of unusual dimensions of 7x4.5x3.5 cm. The soft consistency, slow exophytic growth and bluish-red color suggested an inflammatory hyperplastic nature of the lesion. An excisional biopsy was performed in association with curettage of underlying periosteum. Histological examination revealed presence of spindle-shaped mononuclear cells and multiple multinucleated giant cells in a well vascularized stromal tissue. No calcifications were found. Clinical and histological features suggested the diagnosis of PGCG. This case is clinical evidence of the delays induced by the COVID-19 emergency, which negatively affected all health care and suggests that the PGCG, albeit benign in nature, may have an uncontrolled and non-self-limiting growth, making its surgical removing and healing process more complicated.

ABSTRACT
Objective: Studies have shown that gingival crevices may be a significant route for SARS-CoV-2 entry. However, the role of oral health in the acquisition and severity of COVID-19 is not known. Design: A retrospective analysis was performed using electronic health record data from a large urban academic medical center between 12/1/2019 and 8/24/2020. A total of 387 COVID-19 positive cases were identified and matched 1:1 by age, sex, and race to 387 controls without COVID-19 diagnoses. Demographics, number of missing teeth and alveolar crestal height were determined from radiographs and medical/dental charts. In a subgroup of 107 cases and controls, we also examined the rate of change in alveolar crestal height. A conditional logistic regression model was utilized to assess association between alveolar crestal height and missing teeth with COVID-19 status and with hospitalization status among COVID-19 cases. Results: Increased alveolar bone loss, OR = 4.302 (2.510 - 7.376), fewer missing teeth, OR = 0.897 (0.835-0.965) and lack of smoking history distinguished COVID-19 cases from controls. After adjusting for time between examinations, cases with COVID-19 had greater alveolar bone loss compared to controls (0.641 ± 0.613 mm vs 0.260 ± 0.631 mm, p < 0.01.) Among cases with COVID-19, increased number of missing teeth OR = 2.1871 (1.146- 4.174) was significantly associated with hospitalization. Conclusions: Alveolar bone loss and missing teeth are positively associated with the acquisition and severity of COVID-19 disease, respectively.
