Insights
Preschool children with cerebral palsy (CP) show poorer gingival health, increased tooth wear, and more oral mucosal lesions compared to peers without CP. However, caries experience and dental trauma were similar between groups.
Area of Science:
- Pediatric Dentistry
- Child Health
- Neurology
Background:
- Cerebral palsy (CP) affects motor function and can impact overall health, including oral health.
- Limited research exists on the specific oral health status of preschool children with CP.
Purpose of the Study:
- To compare the oral health status of preschool children with and without cerebral palsy (CP).
- To identify specific oral health differences in children with CP.
Main Methods:
- A case-control study involving 72 preschool children with CP and a matched control group from Hong Kong.
- Assessment of dental caries, gingival health, tooth wear, enamel defects, malocclusion, dental trauma, and oral mucosal health.
Main Results:
- Children with CP exhibited significantly worse gingival health (higher plaque and gingival index scores).
- Increased prevalence of tooth wear into dentine, anterior open-bite malocclusion, and oral mucosal lesions were observed in children with CP.
- No significant differences were found in caries experience, enamel defects, or dental trauma between the groups.
Conclusions:
- Significant oral health disparities exist between preschool children with and without CP.
- Children with CP are at higher risk for poor gingival health, tooth wear, malocclusion, and oral mucosal lesions.
Abstract:
International Journal of Paediatric Dentistry 2010; 20: 330-335 Objectives. To assess and compare the oral health status of preschool children with and without cerebral palsy (CP). Methods. Preschool children with CP (72) were recruited from 23 Special Child Care Centers in Hong Kong. An age (+/-3 months) and gender matched sample of preschool children from mainstream preschools were recruited as the control group. Dental caries status, gingival health status, tooth wear, developmental defect of enamel, malocclusion, dental trauma and oral mucosal health were assessed and compared between the two groups. Results. Significant differences in gingival health status were found between children with and without CP (mean plaque index scores, P = 0.001 and mean gingival index scores, P < 0.05). Tooth wear involving dentine was more prevalent among CP children (P < 0.001), as were evidence of anterior open-bite (P < 0.001) and oral mucosal lesions (P < 0.05). Children with and without CP had similar caries experiences (P > 0.05), prevalence of enamel defects (P > 0.05) and dental trauma (P > 0.05). Conclusions. Differences of oral health status exist among preschool children with and without CP. Preschool children fare worse in terms of gingival health, tooth wear, oral mucosal health and malocclusion.
