Aim of the study: investigate oral lesions associated with COVID-19 in Damascus.

Materials and Methods: A research form including some of the expected lesions to be seen in patients was distributed, and the form was distributed to a group of dentists with different specializations in Damascus Results: Oral manifestations within the research sample ranged from the absence of any oral symptoms at a rate of (0.0697%) to the appearance of a variety of oral lesions ranging between: ulcers (51.16%), halitosis (9.30%), recurrent herpetic lesions (6.97%) and erythematous lesions (5.81%).

Erosions (4.65%), vesicles (3.48%), gingivitis (3.48%), Xerostomia (3.48%), aphthous (1.16%), periodontitis (1.16%), fungi (1.16%) and geographic tongue (1.16%).

The lesions were divided between primary lesions (67.5%) and recurrent lesions (32.5%).

Conclusion: Oral ulcers are the most common oral manifestations in COVID-19 patients, distributed in equal percentage between males and females in the third and fourth decades of life.

They are unilateral and regular painful ulcers and most commonly affect the buccal mucosa.

Other oral manifestations varied between herpetic, erythematous and fungal lesions, in addition to Xerostomia, halitosis, geographic tongue, gingivitis and periodontits in varying degrees.
