Antimicrobial Photodynamic Therapy as an Adjunct Treatment for Periodontal Disease in Down's Syndrome Patients

The aim of this study was to evaluate the effectiveness of antimicrobial photodynamic therapy as an adjuvant of scaling and root planning for treatment of periodontal disease in patients with Down's Syndrome. After scaling and root planning, half of patients received antimicrobial photodynamic therapy with methylene blue dye and laser and the sessions were repeated after 3, 7 and 14 days. The other half received only scaling and root planning.

About this study

Antimicrobial photodynamic therapy (aPDT) has been widely used in Periodontics to obtain reduction of periodontopathogenic bacteria with absence of systemic side effects and minimal bacterial resistance. Therefore, a good adjuvant alternative for periodontal disease treatment arises, especially for patients with Down syndrome (DS) who present greater severity and high prevalence of periodontal disease. Usually aPDT is used as an adjunct therapy to scaling and root planning.

Primary outcomes

  1. Periodontal disease (gingivitis and periodontitis) measured by a periodontal probe and classified according to severity

    Time frame: one year

    Severe periodontitis was defined by the presence of ≥ 2 interproximal sites in different teeth with clinical attachment level (CAL) ≥ 6mm and ≥1 interproximal site with periodontal probing depth (PPD) ≥5mm. Moderate periodontitis was defined by the presence of ≥ 2 interproximal sites in different teeth with CAL ≥ 4mm or ≥ 2 interproximal sites in different teeth with PPD ≥5mm. Mild periodontitis was defined as ≥ 2 interproximal sites in different teeth with ≥ 3 mm CAL and ≥ 2 interproximal sites in different teeth with ≥ 4 mm PPD or at least 1 site with PPD ≥ 5 mm (20,21). Gingivitis was determined as follows: Subjects were considered healthy if presented PPD ≤3mm/ Bleeding on probing (BOP) extent scores < 10% and with gingivitis if presented PPD ≤3mm/ BOP extent scores >10%. Prevalence of periodontal disease was the sum of gingivitis, mild, moderate and severe periodontitis.

Secondary outcomes

  1. Obesity measured by a tape and a scale

    Time frame: one day

    Obese if: body mass index - BMI ≥ 25 Kg/m2 (weight in kilograms, height in meters) Obese if: waist-to-hip ratio - WHR >0.85 for women. >0.9 for men. (measurement in centimeters) Obese if: waist circumference - > 80 cm for women and >94 cm for men.
