Plain English summary of protocol

Background and study aims
Chronic periodontitis is a disease which attacks the tissues surrounding the teeth and has a very high prevalence in adults. As periodontitis progresses, the bones and teeth can be damaged, which can lead to tooth loss if left untreated. Any periodontal pockets that have formed require deep cleaning called scaling and root planing in order to enable healing. In some severe cases, the deep cleaning is combined with other treatment options in able to improve the therapy outcome. Photoactivated disinfection is a treatment method that is associated with the use of a light source and a photosensitizer to disinfect the area and clear bacteria. The aim of this study is to investigate photoactivated disinfection as a complementary treatment to conventional periodontal treatment such as deep cleaning.

Who can participate?
Adults aged over 35 with periodontitis

What does the study involve?
All participants will receive the same treatment - standard periodontal treatment (deep cleaning) on both sides of the mouth. Each participant will have one side of their mouth randomly allocated to receive photoactivated disinfection.

What are the possible benefits and risks of participating?
The possible benefit of participating is that photoactivated disinfection may improve the success of regular gum treatment. The possible risk is that the dye used in the treatment may result in transient staining of the oral mucosa.

Where is the study run from?
University Clinical of Dentistry, Medical University of Vienna, Austria

When is the study starting and how long is it expected to run for?
October 2014 to June 2016

Who is funding the study?
Medical University of Vienna (Austria)

Health condition(s) or problem(s) studiedChronic periodontitis
InterventionParticipants were randomised into a split-mouth design, with allocation of the side to be treated (left or right) performed by drawing lots before the initial periodontal examination.
Clinical and microbiological parameters were evaluated in the initial examination. Subsequently, supra and subgingival debridement was performed using ultrasonic instruments, universal curettes and Gracey curettes. One side of each study participant’s upper and lower jaws was treated with photoactivated disinfection during the two final cleaning sessions. The contralateral side remained untreated and served as a control. Adjuvant treatment was carried out at six locations around all teeth (mesiobuccal, buccal, distobuccal, mesiolingual, lingual and distolingual), and protective eyewear was provided to all participants. The photosensitizer, a 0.01% tolonium chloride solution, was applied to the pocket and after 60 seconds the area was irradiated with light for 60 seconds per location according to the manufacturer. The pockets were than irrigated with physiological saline solution. Clinical and microbiological parameters were repeated 12 weeks after initial treatment.

Primary outcome measureBleeding on probing, assessed during probing with a calibrated standard probe at the initial examination (baseline) and 12 weeks after the last treatment (re-evaluation)
Secondary outcome measures1. Oral hygiene, assessed using The Approximal-Plaque-Index (API) and the Papillary Bleeding Index (PBI) at the initial examination (baseline), at debridement and 12 weeks after the last treatment (re-evaluation)
2. Clinical attachment level, measured to the nearest millimeter using a calibrated standard probe at baseline and re-evaluation
3. Periodontal pocket depth, measured to the nearest millimeter using a calibrated standard probe at baseline and re-evaluation
