Photodynamic Therapy During Supportive Periodontal Therapy

January 27, 2016 updated by: Goh Xian Jun Edwin, National University, Singapore

Effects of Photodynamic Therapy on Clinical and Immunological Parameters in a Group of Periodontal Patients Undergoing Supportive Periodontal Therapy

27 subjects on SPT, each with at least two residual pockets ≥5mm, were recruited for this randomised, split-mouth controlled trial, providing a total of 72 sites. At baseline, probing pocket depth (PPD), recession, clinical attachment level (CAL), plaque and bleeding on probing (BOP) of all sites were examined. Gingival crevicular fluid (GCF) were collected to determine level of cytokines IL-1β, -6, -8, TNF-α and MMP-8 via ELISA. Control sites received subgingival instrumentation and rubber cup polishing with pumice. In addition test sites received a single application of PDT using Fotosan® and photosensitizer consisting of toludine blue O solution. The subjects were recalled three and six months later and re-examined. Site level analysis was performed.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
27

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
  • Phase 4

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Photodynamic therapy protocol
In addition to scaling and root debridement, test sites received PDT according to manufacturer's instructions.
Device: Fotosan 630, CMS Dental, Copenhagen, Denmark
The PDT system consists of a hand-held rechargeable light-emitting diode (LED) light source (Fotosan® 630 device, CMS Dental, Copenhagen, Denmark) and 0.1 mg/mL toluidine blue photosensitiser. The LED light source has a wavelength between 620 to 640 nm and peak of 630 nm and a power density between 2000 to 4000 mW/cm2.
Other: SRP
Scaling and root debridement of the residual pockets were performed using ultrasonic device and hand curettes until root surfaces felt hard and smooth. The sites were then polished using rubber cup and prophylaxis paste.
Other: Scaling and root planing
Scaling and root debridement of the residual pockets were performed using ultrasonic device and hand curettes until root surfaces felt hard and smooth. The sites were then polished using rubber cup and prophylaxis paste.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Difference in percentage change in probing pocket depth
Time Frame: 6 months
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Bleeding on probing
Time Frame: 6 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2013

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
