To investigate serum, placental levels of active-matrix metalloproteinase-8 (aMMP-8), myeloperoxidase (MPO) in preterm-birth with/without pre-eclampsia and term counterparts in relation with clinical periodontal parameters. Clinical periodontal measurements were recorded. Serum and placenta samples were collected during 173 full-term (FT), pre-term (PT) or pre-term complicated by pre-eclampsia (PTPE) deliveries. aMMP-8 levels were measured by IFMA. MPO levels in the serum and placenta samples were determined by ELISA. Data were tested using non-parametric tests. PTBE group exhibited higher full-mouth probing depth and clinical attachment loss values than the other two groups (p < 0.05). Percentages of sites with plaque and bleeding on probing were lower in the PTBE group than in the other groups (p < 0.05). Serum aMMP-8 and MPO concentrations were higher in PTPE group than in the other groups (p < 0.05). Placenta aMMP-8 level was higher in the control group than in the PTPE group (p < 0.05). There was no significant difference between the groups in the placenta MPO levels (p > 0.05). Within the limits of this cross-sectional study, it may be suggested that serum aMMP-8 and MPO concentrations together with placenta aMMP-8 levels may be associated with and reflect adverse pregnancy outcomes. Clinical periodontal findings did not reveal significant associations with these proteolytic and oxidative biomarkers.
