A review of oral-facial side effects of covid-19 vaccines

The purpose of this review is to collect the oral-facial complications caused by the covid-19 vaccines and to know the reasons for their occurrence.

An electronic search without date restrictions was performed in the MEDLINE databases through PUBMED and google scholar. Among the 50 studies after removing duplicates, 11 articles that met the inclusion criteria were reviewed and included in the study.

Studies have shown that the injection of Covid-19 vaccines may cause oral side effects such as lichen planus, erythema multiforme, Steven Johnson syndrome, mucositis, and Bell's palsy. Bell's palsy (6023 cases), skin and mucosa itching (39 cases), erythema multiforme (6 cases), lichen planus (6 cases), Steven Johnson syndrome (3 cases), mucositis (1 case), angular cheilitis (1 case) ), pemphigus vulgaris (1 case) and one case with unknown cause. Pfizer vaccine is the most complicated vaccine reported in this study.

Considering the high prevalence of covid-19 and the subsequent injection of covid-19 vaccines in order to prevent this disease, diagnosis and treatment of possible complications, especially oral and facial complications after vaccination, are of great importance.
