Area of Science:

  • Oral Medicine
  • Behavioral Science

Background:

  • Bruxism, the involuntary grinding or clenching of teeth, is a multifactorial condition.
  • The relationship between smoking habits and bruxism symptoms requires further elucidation.

Purpose of the Study:

  • To investigate the association between smoking status and the experience of bruxism symptoms.
  • To differentiate the link between smoking and bruxism from general stress experiences.

Main Methods:

  • A comparative study design was employed.
  • Participants included 18 smokers and 165 nonsmokers.
  • Symptom experience was assessed using two specific items related to bruxism.

Main Results:

  • Smokers demonstrated a significantly higher likelihood of reporting bruxism symptoms.
  • The odds of experiencing bruxism symptoms were approximately three times greater in smokers.
  • This increased likelihood was not observed for general stressful experiences, indicating specificity.

Conclusions:

  • Smoking appears to be a notable risk factor for experiencing bruxism symptoms.
  • The findings suggest a specific link between smoking and bruxism, independent of overall stress levels.
  • Further research is warranted to explore the underlying mechanisms connecting smoking and bruxism.
