Background : The aim of this study was to investigate the existence of associations between bruxism and psychic and occlusal factors. Methods : Participants in this study (n=85) were recruited from the Section of Odontostomatology, Department of Neuroscience, University of Pisa, Italy. They were split into two groups, bruxers (n=34) and non‐bruxers (n=51), on the basis of the presence of both clinical and anamnestical indicators of bruxism. All participants were administered two self‐reported validated questionnaires to evaluate mood (MOODS‐SR) and panic‐agoraphobic (PAS‐SR) spectra. A number of occlusal variables (deep‐bite, cross‐bite, open‐bite, mediotrusive and laterotrusive interferences, slide RCP‐ICP, laterotrusive guides, canine and molar classes) were also recorded. Results : With regards to occlusal factors, the only association was revealed between bruxism mediotrusive interferences (p<0.05). As for psychiatric investigation, significant differences between bruxers and controls emerged for the presence of both depressive (p<0.01) and manic symptoms (p<0.01) in MOODS‐SR, and for stress sensitivity (p<0.01), anxious expectation (p<0.05), and reassurance sensitivity symptoms (p<0.05) in PAS‐SR. In particular, both mood (p<0.01) and panic‐agoraphobic (p<0.05) spectra symptoms seem to differentiate bruxers from controls in males, while in females strong differences emerged for stress sensitivity symptoms (p<0.05). Conclusions : It can be confirmed that certain psychic traits are present in bruxers, while occlusal factors are not useful parameters to discern bruxers from non‐bruxers.
