Evaluation of oral health conditions among children with special health care needs using clinical records

Background: Oral health is a vital component of overall well-being, yet children with special health care needs (CSHCN) are disproportionately affected by dental diseases due to physical, cognitive, behavioral, and systemic factors. Methods: A retrospective cross-sectional analysis was conducted on clinical records of 500 CSHCN aged 2-17 years, collected from pediatric dental clinics and special care centers in Nanjing, China. Lifestyle, nutrition, oral health, and socio-demographic data were extracted. Caries experience (dmft/DMFT), gingival condition, plaque accumulation, malocclusion, and dental hygiene were assessed. Chi-square tests and one-way ANOVA explored associations between clinical diagnosis and oral health outcomes. Multiple logistic regression identified factors independently associated with dental caries. Results: = 0.001) as factors significantly associated with dental caries. Age was also associated with increased caries risk, while sex, BMI, residence, and diagnosis category were not. Conclusion: Special needs children have increased rates of dental cavities, gingivitis, plaque accumulation, and malocclusion, as well as poor oral hygiene and limited preventive care. Dental caries risk is associated with oral hygiene practices, sugar intake, and fluoride use, suggesting the need for targeted preventive measures, caregiver education, and improved CSHCN-specific dental services.
