Lockdown impact on lifestyle and its association with oral parafunctional habits and bruxism in a Spanish adolescent population.

AIM
to analyse the possible association between decreased physical and social activity and an increase in the use of mobile devices, internet and social networks with increased anxiety and the appearance of oral parafunctions and bruxism.


DESIGN
213 adolescents attended private clinics at two different times: before lockdown (T0) and after completion of total lockdown (T1). In T0 and T1 a clinical examination was carried out to assess dental wear (IA) and only in T1 were they given the self-report questionnaire which focuses on the periods before and during lockdown (self-reported bruxism, state-anxiety, mobile phone and internet, social network use, physical and social activity and questions on parafunctions).


RESULTS
There was a decrease in physical activity at T0-T1 and an increase in social media use, internet, state-anxiety, clinical and self-reported bruxism at T0-T1. There was a positive correlation between increased self-reported bruxism, increased social media use, mobile device use and state-anxiety.


CONCLUSIONS
There has been a change in adolescent lifestyle during lockdown with an increase in the appearance of oral parafunctions and bruxism. In particular, the increase in the use of social networks at night and also in anxiety levels during lockdown are predictors of the increase in self-reported bruxism.
