Comparison Between aPDT and Systemic Doxycycline on Non-surgical Periodontal Therapy in Type 2 Diabetics

July 15, 2014 updated by: Arthur Belem Novaes Jr, University of Sao Paulo

Effect of a PDT Protocol With Multiple Applications as an Adjuvant on the Non Surgical Treatment of Periodontal Disease in Patients With Type 2 Diabetes. A Clinical and Laboratorial Study in Humans

The objective of this study is to evaluate Photodynamic Therapy (PDT) as adjunct on non surgical periodontal therapy in patients with type 2 diabetes. A total of 40 individuals will be selected and divided in two groups. On the treatment stage, the control group (Group C) will receive standard non surgical periodontal treatment. The Test Group (Group T) will be treated with PDT as an adjunct to non surgical periodontal treatment. The treatment will be repeated 4 times in two weeks, followed by dental prophylaxis every 15 days until accomplish 3 months. The follow-up will be done for 6 months. The clinical parameters measured will be: plaque index, pocket depth, bleeding on probing, relative clinical insertion level and suppuration. In addition, the evaluation of crevicular fluid volume and the levels of IL-1, TNF-α, subgingival microbiota by the hybridization DNA-DNA Checkerboard technique. The investigators expect to find identical or better results for the test group.

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.

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.

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.

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
Measure Description
Time Frame
Clinical Attachment Level
Time Frame: 0, 1 month, 3 months and 6 months
There will be analyzed the changes in clinical attachment level at the proposed experimental times. Clinical attatchment level is known as a proper outcome to evaluate periodontal disease progression or regression. It is measured as the distace between the deepet point fo the periodontal pocket and a stabilshed point, on the case of this study, the tooth occlusal surface.
0, 1 month, 3 months and 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
Measure Description
Time Frame
Microbial Load
Time Frame: 0, 3 months and 6 months
There will be mesaured the changes of microbial load at the proposed experimental times. Microbial load at deep pocket seems to change regarding periodontal treatment and it is expected a reduction after treatment. measuring on various experimental times it will be possible to evaluate treatment stability on reducing periodontopathogens.
0, 3 months and 6 months

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.
