Supragingival Microbiota Alterations in Individuals With Sleep Bruxism: A Pilot Study.

ABSTRACT:

Background

Sleep bruxism (SB) is an oral behaviour associated to jaw clenching or grinding of the teeth. Its aetiology is most likely multifactorial; however, recent studies suggested that SB is associated with activation of the sympathetic nervous system. Dysbiosis of the oral microbiota is linked to oral and systemic diseases. The relationship between supragingival microbiota and SB remains unexplored.

Objective

This study aimed to investigate the association between SB and the composition of the supragingival microbiota.

Methods

Nineteen metabolically and orally healthy subjects were recruited. After SB diagnosis, supragingival microbiota samples were collected. Microbial DNA was extracted and subjected to 16S rRNA gene sequencing. Amplicon sequence variant (ASV) a
