Abstract

This study aims to investigate the impact of a tooth-brushing guidance system on the enchancement of the dental plaque removal in preschool children. In this study, we selected a group of 124 healthy children in which their aged were between 3 and 5 years old following by treatment at the Pediatric Dentistry Center at Jinzhou Stomatological Hospital (JinZhou, Liaoning Province, China). We then followed up to check and identify the Turesky modification of the Quigley-Hein plaque index (TMQHPI). Study group was randomly assigned to an experimental group in which they received constantly guidance on intelligent tooth-brushing and a control group which was used by manual brushing techniques. The total numbers in each group were 62 participants that were gone under the clinical investigation for seven days. The plaque index of both groups were assessed by using a plaque display instrument and a periodontal probe for up day 28. It was shown that the experimental group had a lower average TMQHPI value (0.98 ± 0.15) in comparison with control group (1.41 ± 0.17), and this difference was statistically significant (p < 0.05). The experimental group had a significantly lower TMQHPI value (0.89 ± 0.13) on the tongue/palatal side of the anterior teeth area in comparison with control group (1.41 ± 0.17) (p < 0.05). We observed that experimental group showed significantly lower TMQHPI value (1.16 ± 0.12) on the tongue/palatal side of the posterior dental region in comparison with control group (1.70 ± 0.13) (p < 0.05). It was confirmed a significant difference in the average plaque clearance rate between the experimental and control groups (p < 0.05). Our study clearly indicates that a developed method of toothbrush guide effectively improved the removal rate of plaque compared with manual tooth-brush, specifically in hard-to-reach areas like the tongue and palate.
