The primary objective of this study was to evaluate whether an interdental hygiene intervention in early pregnancy could reduce obstetrical complications. Exploratory analyses focused on potential biological pathways linking oral inflammation and obstetrical outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>A two\u2010arm randomised controlled trial (RCT) with cluster allocation (1:1) was conducted in six antenatal clinics in Senegal among nulliparous women at 12\u2009weeks. Participants received either a daily calibrated interdental brushing intervention (Intervention) or usual oral hygiene (Control). Follow\u2010up visits were scheduled at 5 and 8\u2009months. The primary endpoint was a composite of preterm birth, low birth weight, small for gestational age or pre\u2010eclampsia, analysed exploratorily under the intention\u2010to\u2010treat principle.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 323 women were randomised (162 intervention, 161 control).

Exploratory analyses suggested that interdental bleeding and C\u2010reactive protein (CRP) could act as mediators, accounting for ~60% of the effect, with the remaining ~40% representing a direct effect.
