Non-surgical periodontal therapy with adjunctive chlorhexidine use in adults with down syndrome: a prospective case series.

Background: Subjects with Down syndrome (DS) experience a high prevalence of periodontal disease, and the management of this disease in subjects with DS is a challenge for oral health care providers. The purpose of this case series was to follow the periodontal healing response changes over a 12-month period after non-surgical mechanical periodontal therapy with the adjunctive use of chlorhexidine and monthly recalls in adults with DS who presented initially with chronic periodontitis.

Methods: Twenty-one subjects with DS (14 males and seven females; 25.3 +/- 5.5 years of age) with reported mild-to-moderate learning disabilities and chronic periodontitis were recruited and treated by non-surgical mechanical periodontal therapy (followed by monthly recalls) and the adjunctive use of chlorhexidine gel for toothbrushing and chlorhexidine mouthwash twice daily. Clinical data were recorded.

Results: After 12 months of non-surgical mechanical periodontal therapy, the mean percentage of sites with plaque decreased from 84.1% to 23.6%, and the mean number of sites with bleeding on probing decreased from 82.1% to 29.5%. Mean probing depth decreased from 3.2 to 1.8 mm, with a mean clinical attachment level gain of 0.6 mm.

Conclusions: Satisfactory healing responses were achieved following non-surgical mechanical periodontal therapy with the adjunctive use of chlorhexidine and monthly recalls in adults with DS with chronic periodontitis and mild-to-moderate learning disabilities. Such a treatment regimen seems appropriate and beneficial for adults with DS and chronic periodontitis.
