Purpose: To compare the effectiveness of two varieties of special needs toothbrushes in terms of dental plaque removal and bacterial contamination vs a conventional toothbrush in patients with Down syndrome.
Materials and Methods: This single-blinded, two-group, randomised clinical trial included 16 patients diagnosed with Down syndrome (age 6–15 years) from various special needs centers located in the Jazan Province of Saudi Arabia. The patients were randomly allocated to two groups based on the type of special needs toothbrush provided (Collis Curve or superfine nano). The plaque and bleeding indices of the patients in both groups were measured at baseline (T0) and both groups were initially given a conventional toothbrush to use for four weeks. After this period, the plaque and bleeding indices were re-evaluated (T1). The patients were instructed to use the special needs toothbrush for 4 weeks, after which the periodontal indices were re-evaluated (T2). Microbial contamination on the bristles of the special needs brushes was evaluated at T2.
Results: No notable changes in the mean plaque and bleeding indices were observed between the two groups at each visit; however, statistically significant reductions were noted between visits in both groups (p < 0.05). The CFU scores in cultures from the Collis Curve toothbrush bristles (1411.5 ± 541.1) were higher than those obtained from the superfine nano-toothbrush bristles (1118.3 ± 423.9), but without statistically significant differences.
Conclusion: The findings indicate that the use of special needs toothbrushes can statistically significantly improve the gingival health status in individuals with Down syndrome in terms of both resolution of periodontal inflammation and reduction of plaque accumulation.
