Association between child's behaviour during first dental appointment and effectiveness of dental plaque removal by caregivers

Abstract

Objective: To evaluate the association between the behaviour of children aged 1 to 4 years during their dental appointment and the effectiveness of dental plaque removal by caregivers.

Methods: This longitudinal study with intervention had the participation of 146 children (mean age = 34.89 months), 75 of whom (51.4%) showed positive behaviour (+ and ++) and 71 (48.6%), negative behaviour (- and - -). The children were evaluated at the first dental appointment, according to the Frankl scale. They were subjected to an assessment of oral conditions, and their plaque level was recorded (Quigley-Hein Index modified by Turesky) using the Evince® device. Caregivers received oral hygiene guidance. The dental plaque assessment was performed before giving the oral hygiene guidance and 14 days later. The statistical analysis included a descriptive assessment and the Wilcoxon test (p < 0.05).

Results: Mean dental plaque levels dropped significantly from the first to the second assessment (p < 0.001). The sample was divided according to the child's behaviour, observing that only the group of children with positive behaviour showed significantly less dental plaque in the second assessment (p < 0.001).

Conclusion: The positive behaviour of children aged 1 to 4 years during the first dental appointments is associated with more effective dental plaque removal by caregivers.
