Project Overview

The MIOH program demonstrated a positive impact on the oral health status and practices of women during pregnancy. To build on this, this two-phase study aimed to assess the long term effectiveness of the MIOH program in reducing early childhood caries among children whose mothers received this intervention.

Aims & Objectives

The broad aim of this study was to assess the effectiveness of the MIOH program in improving the oral health outcomes of children after birth. It involved following up pregnant women and their children that were involved in the multicentre trial. The specific aims are to determine the impact of the MIOH program on:

  1. Knowledge of mothers regarding oral health care for children.
  2. Oral health behaviours among children (dentist visits/oral hygiene/eating/feeding habits)
  3. Oral health status and prevalence of dental decay among children
