• Objective: To compare the effect of planning interventions on self-reported changes in parents supervised oral health-related behaviors (OHRBs) and associated clinical oral health parameters for primary school-age children.

  Method and materials: In total, 110 parent–child pairs (children aged 3 to 8 years) were randomly assigned to either of the two groups. In the “action planning” group, parent participants of the pair were asked to make an “action plan” using the “how, when, where” format for their child OHRBs. In the “implementation intention” group, parents were asked to form an “if-then plan” to improve OHRBs for their child. Self-reported changes on target OHRBs, change in plaque scores, change in plaque stagnation areas, and change in caries status of tooth surfaces were observed at 2, 8, and 12 weeks.

  Results: Overall OHRBs scores changed significantly from baseline to 12 weeks for both interventions. The scores were significantly better with “if-then” planning than “action planning” (z = 4, P < .001) at 12 weeks. Plaque scores also changed significantly from baseline to 12 weeks for both interventions, and improved significantly more with “if-then” planning (16.20 ± 5.24) than “action planning” (50.66 ± 11.24) at 12 weeks. The number of plaque stagnation areas also changed significantly from baseline to 12 weeks for both interventions, and improved significantly more with “if-then” planning at 12 weeks (12.80 ± 5.33) than “action planning” (42.76 ± 10.34) (t = −11.55, P < .001). There was significant change in the caries status of sound tooth surfaces with “action planning” at 12 weeks (z = 116.50, P = .023). There were no new caries lesions reported with “if-then” planning at 12 weeks.

  Conclusion: The study observed significant improvement in OHRBs and associated oral health parameters with planning interventions, preferring “if-then” planning over “action planning.” It also elicited significant barriers to behaviors in action.
