Abstract

Adverse pregnancy outcomes are associated with poor oral health and low oral health literacy among
expectant mothers. However, little is known about the effectiveness of Oral Health Education (OHE)
interventions particularly developed for pregnant women. The aim of the systematic review was to
examine the effectiveness of OHE on the knowledge, attitude, and performance towards oral health among
pregnant women and their oral health/hygiene status. The electronic search was performed across:
MEDLINE via PubMed, EMBASE via OVID, Cochrane Central Register of Controlled Trials, PubMed
Central, Google Scholar, ClinicalTrials.gov, and ISRCTN. Randomized controlled trials and quasi studies
were included with Inclusion criteria of participants being pregnant, any trimester. The education
intervention was mostly compared with no intervention or a different mode of intervention. All the
included studies addressed at least one of the primary objectives and/or a combination of a primary and the
secondary objective. A total of 1977 papers were initially identified, of which 11 studies were included.
The primary outcomes of interest were knowledge (11/11), change in attitude (3/11), change in
performance (9/11), and the secondary outcome was oral health status/hygiene (6/11). Upon intervention, a
significant improvement in knowledge (91%, 10/11), attitude (100%, 3/3), performance (100%, 9/9), and
oral health/hygiene status (100%, 6/6) was found across the studies. Nevertheless, improvement was also
observed with no intervention group across a few studies, but less than the intervention group. However,
owing to the design faults and limited use of health behaviour theories across included studies only low
confidence can be placed on the current evidence.

Key words: Education intervention, oral health education, pregnant women
