Findings

Population Adults with primary burning mouth syndrome (pBMS) and healthy controls

4 findings

Primary burning mouth syndrome (pBMS)Healthy controlsRegional grey matter volume (voxel-wise SDM-PSI meta-analysis)
Decreased GMV: left medial superior frontal gyrus (mPFC), MNI -8, 58, -2
SDM-Z -3.341
GRADE not reported

Primary burning mouth syndrome (pBMS)Healthy controlsRegional grey matter volume (voxel-wise SDM-PSI meta-analysis)
Jackknife sensitivity analysis of left mSFG reduction
Reduced GMV in the left mSFG remained significant in 2 of 4 leave-one-out combinations (remained when Sinding et al. or Lee et al. omitted; not when Khan et al. or Tan et al. omitted)

Overlap with other reviews

Reviews that include the same primary studies are not independent evidence. Shared counts match studies by PMID, DOI or NCT, and otherwise by author and year (a probable match). Only the non-Cochrane dental reviews have study lists, so overlap with Cochrane reviews is not counted yet.

Review question

ElementPlanned (methods)Found (results)
PopulationPatients diagnosed with primary burning mouth syndrome (ICHD criteria)pBMS patients (n=59 structural; n=35 functional) from 4 VBM studies
InterventionNeuroimaging: voxel-based grey matter analyses (T1-weighted) and resting-state functional connectivity (BOLD fMRI)pBMS neuroimaging: 4 VBM studies; 2 resting-state fMRI studies (same participants as 2 of the VBM studies)
ComparisonHealthy controls or comparable reference groupHealthy controls (n=63 structural; n=36 functional)
OutcomesRegional grey matter volume differences (peak coordinates); resting-state functional connectivityDecreased GMV in left medial superior frontal gyrus (mPFC); exploratory increased mPFC-left amygdala functional connectivity
