Abstract:
The aim of the PAROBRAIN study was to examine the association of periodontal health with microstructural white matter integrity and cerebral small vessel disease (CSVD) in the Hamburg City Health Study, a large population‐based cohort with dental examination and brain magnetic resonance imaging (MRI). Materials and Methods Periodontal health was determined by measuring clinical attachment loss (CAL) and plaque index. Additionally, the decayed/missing/filled teeth (DMFT) index was quantified. 3D‐FLAIR and 3D‐T1‐weighted images were used for white matter hyperintensity (WMH) segmentation. Diffusion‐weighted MRI was used to quantify peak width of skeletonized mean diffusivity (PSMD). Results Data from 2030 participants were included in the analysis. Median age was 65 years, with 43% female participants. After adjusting for age and sex, an increase in WMH load was significantly associated with more CAL, higher plaque index and higher DMFT index. PSMD was significantly associated with the plaque index and DMFT. Additional adjustment for education and cardiovascular risk factors revealed a significant association of PSMD with plaque index ( p 〈 .001) and DMFT ( p 〈 .01), whereas effects of WMH load were attenuated ( p 〉 .05). Conclusions These findings suggest an adverse effect of periodontal health on CSVD and white matter integrity. Further research is necessary to examine whether early treatment of periodontal disease can prevent microstructural brain damage.
