Despite apparent conflicting data, the majority of studies
report that periodontal treatment is safe for pregnant women
and improve periodontal status [3, 90, 92, 94]. The pregnant
woman is a particular patient. In order to decrease the
impact of periodontal disease on preterm birth incidence,
the early diagnosis promotion of periodontal disease for
young women especially for those presenting major risk
factors should be recommended. The preventive oral care
is the best way to prevent oral diseases and their consequences
on pregnancy [96]. In case of periodontal disease
diagnosis done during pregnancy, a frequent monitoring
of the patient should be positive for the control of the
disease and the decrease of preterm birth risk. For severe
or aggressive periodontitis, metronidazole or amoxicillin
could be used in addition to mechanical treatments. Studies
have been performed on the effect of antibiotic on rate of
preterm birth concerning bacterial vaginosis. The majority
of them demonstrates no deleterious effect of antibiotic
use on pregnancy outcome especially for metronidazole
