			SUMMARY
			
				
				Introduction/Aim. Various psychological factors that arose 
				during the COVID-19 pandemic could contribute to the development 
				of chronic emotional stress which is the biggest contributor to 
				the development of temporomandibular disorders (TMDs). This 
				research aimed to evaluate the corellation between TMD and 
				COVID-19 pandemic among students.
				
				Methods. The authors conducted the study at the Faculty of 
				Medicine in Niš, using an anonymous online survey, during two 
				different periods, in 2022 at the peak of the pandemic and in 
				2023 after the WHO declared the end of the pandemic.The 
				questionnaire consisted of questions that evaluate the influence 
				of COVID-19 on patients’ life as well as the questions from the 
				Fonseca questionnaire. 
				
				Results. The sample consisted of 363 (2022) and 212 (2023) 
				examinees. Statistical significance was determined using the χ2 
				test. Students with TMDs were more prevalent in 2023 than in 
				2022 (83% vs 76%). TMDs were significantly more present among 
				the female examinees (p < 0.001). Significance was not 
				determined among examinees based on the study group, vaccination 
				status, or based on whether they or their loved ones were 
				affected by COVID-19.
				
				Conclusion. Evidence of significantlly high number of TMDs was 
				found among students. It could be linked to COVID-19 pandemic 
				due to a large number of stresogenic factors that affect the 
				students.
