Purpose:
Children with special healthcare needs (SHCN) often experience poorer oral health due to limitations in self-care, behavioral challenges, medical conditions, and reduced access to specialized dental services. This study aimed to assess and compare oral health behaviors, risk factors, and caries experience between children with SHCN and healthy controls, and to identify predictors of poor oral health outcomes.
Method:
In this cross-sectional study, 300 children (150 SHCN, 150 controls) underwent clinical examinations. Caries experience was assessed using the decayed, missing, and filled teeth (dmft/DMFT) indices, while oral hygiene status was evaluated with the Plaque Index and Gingival Index. Occlusal characteristics, dental trauma, and oral habits were also recorded. Behavioral assessment was performed using the Frankl Behavior Rating Scale (FBRS).
Results:
Children with SHCN demonstrated higher resistance to toothbrushing (42.7% vs. 6.7%, p = 0.001), more frequent swallowing of toothpaste (32.0% vs. 0%, p = 0.001), and a greater prevalence of habits such as mouth breathing (30.7% vs. 8.7%, p = 0.001). Interestingly, the control group showed significantly higher mean dmft scores (5.07 ± 3.56) compared to SHCN children (2.64 ± 4.22, p = 0.001). Regression analysis identified group (B = 2.44, p < 0.001) and age (B = - 0.125, p = 0.002) as significant predictors, explaining 12.2% of the variance. SHCN children exhibited distinct behavioral risk factors, while younger age was associated with higher caries experience.
Conclusion:
Children with SHCN exhibited significantly poorer oral health behaviors, including resistance to brushing, swallowing toothpaste, and abnormal oral habits, compared to controls. Interestingly, despite these behavioral disadvantages, caries experience was higher in the control group, underscoring the multifactorial and complex nature of caries development. Group type and age emerged as significant predictors of dmft.

Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
