This critical summary of a systematic review published in 2010 was prepared under the auspices of the American Dental Association Center for Evidence-Based Dentistry.
The original review authors were looking at the relationship between oral health-related quality of life (OHQOL) and temporomandibular disorders (TMDs).
The critical summary noted that the review question could have been more clearly defined and more methodological details could have been provided in several areas. Because of variability between the studies a numerical estimate of the impact of TMDs on OHQOL was not conducted so a narrative summary was provided.
While the original review authors noted that TMDs had a negative impact on OHQOL the summariser notes that the quality of evidence supporting this is difficult assess owing to methodological weakness in the review.
