Comments on
The Evidence
Validity: This was a case-control study with the control group similar to the addict group. The groups were treated the same and the examiner was blind to the subject’s answer’s to the questionnaire. However, the examiner was not blind to what group the subject belonged to. The sleep bruxism had to be evaluated by wear facets and self-reports of headache and stiffness in the morning. Perspective: The study did not look at the other factors associated with drug addicts. This includes the emotional stress, combination of drugs, prison time, and nutritional habits. The study was also not strictly focused on Heroin addicts and most subjects were male.
Applicability Patients with known drug addictions need to be evaluated and monitored for oral para-functional habits. Those with these habits need to be given treatment such as an oral appliance to help prevent tooth destruction and muscle soreness.
