About this study

Official title: Photodynamic Therapy Associated With Full-mouth Ultrasonic Debridement in the Treatment of Severe Chronic Periodontitis: a Randomized-controlled Clinical Trial Running Title: Photodynamic Therapy Associated With Periodontal Debridement

Background: Photodynamic therapy (PDT) is a method of microbial reduction which can benefit periodontal treatment in areas of difficult access, such as deep pockets and furcations. The aim of this randomized controlled clinical trial was to evaluate the effects of PDT as an adjunct to full-mouth ultrasonic debridement in the treatment of severe chronic periodontitis.

Methods: Twenty-two patients with at least one pocket with probing depth (PD) ≥ 7 mm and one pocket with PD ≥ 5 mm and bleeding on probing (BOP) on each side of the mouth were included, characterizing a split mouth design. The control group underwent full-mouth ultrasonic debridement and test group received the same treatment associated with PDT. The following clinical parameters were evaluated: plaque index, gingival index, BOP, gingival recession (GR), PD, and clinical attachment level (CAL). All parameters were collected before, 1, 3 and 6 months after treatment.

Read the detailed description

The present study was a randomized, blinded, controlled clinical trial, which used a split-mouth design. Prior to commencement, the study design was approved by the Ethics Committee of Bahiana School of Medicine and Public Health (12/2008). All patients were informed individually about the nature of the proposed treatment, and informed consent forms were signed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Also called debridement using an ultrasonic scaler, Specific tips were used, 0.005% methylene blue dye, low power laser - AsGaAl

    At least two teeth (one with PD ≥ 7 mm and another with PS ≥ 5 mm) were randomly assigned (by coin toss) to one of the treatments: with (test group) or without PDT (control group). After random allocation, all patients received full-mouth ultrasonic debridement using an ultrasonic scaler for 1 hour. Specific tips were used. PDT was performed on only one side of the mouth and the initial step was subgingival irrigation with 0.005% methylene blue dye. To avoid contamination of the control sites with the dye, the methylene blue was applied only inside the periodontal pockets and a high-powered suction device controlled the flow. Two minutes after applying the photosensitizer, the low power laser - AsGaAl was applied for 90 seconds.

Study groupRoleWhat they receive
laser and methilene blueExperimentalAfter random allocation, all patients received full-mouth ultrasonic debridement using an ultrasonic scaler (Profi III Bios, Dabi Atlante, Ribeirão Preto, São Paulo, Brazil) for 1 hour. Specific tips were used (Perio sub, Dabi Atlante, Ribeirão Preto, São Paulo, Brazi). PDT was performed on only one side of the mouth and the initial step was subgingival irrigation with 0.005% methylene blue dye. To avoid contamination of the control sites with the dye, the methylene blue was applied only inside the periodontal pockets and a high-powered suction device controlled the flow. Two minutes after applying the photosensitizer, the low power laser - AsGaAl (Photon Laser III - PL7336, DMC, São Carlos -São Paulo, Brazil) was applied (660 nm, 100 mW, 9 J, 90 seconds per site, 320 J/cm2).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in clinical attachment level

    Photodynamic therapy associated with full-mouth ultrasonic debridement in the treatment of severe chronic periodontitis: a randomized-controlled clinical trial Running title: Photodynamic therapy associated with periodontal debridement

    Measured: 1,3, 6 months

  2. Photodynamic therapy and periodontitis chronic severe

    An improvement in BOP, PD and CAL was observed after treatment, in both groups, but without difference them.

    Measured: 1 and 3 months

Secondary outcomes (1)
  1. changes in clinical attachment level Running title: Photodynamic therapy associated with periodontal debridement Photodynamic th

    An improvement in BOP, PD and CAL was observed after treatment, in both groups, but without difference them. After 6 months, PD decreased from 5.11 ± 0.56 mm to 2.83 ± 0.47 mm in test group (p<0.05) and from 5.15 ± 0.46 mm to 2.83 ± 0.40 mm in control group (p<0.05). The CAL changed, after 6 months, from 5.49 ± 0.76 mm to 3.41 ± 0.84 mm in th test group (p<0.05) and from 5.53 ± 0.54 to 3.39 ± 0.51 mm in control group (p<0.05).

    Measured: 1,3, 6 months

Questions about this trial

What is this clinical trial studying?

A study testing photodynamic therapy and periodontal debridement in people with Chronic Periodontitis, run by Escola Bahiana de Medicina e Saude Publica.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in clinical attachment level (time frame: 1,3, 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2012.
