About this study

Official title: Effectiveness of Two Non-surgical Periodontal Treatment Protocols: Randomized Controlled Clinical Trial

Periodontitis is a form of gum disease that affects many people in the world. Its traditional protocol of treatment includes oral hygiene instruction and dental scaling to remove debris, dental plaque and tartar in 4 weekly sections. There is an additional time-reduced option also usually cheaper. In this last one, all above described procedures are performed within 24 hours. However, up to now comparative effectiveness between these both types of treatment is not well understood. For, example it is not clear if patients treated in the shorter-time experienced more pain. Therefore, the present study used several parameters to clarify whether beneficial differences between these therapeutic protocols exist or not. In addition, aspects that could help clinicians' and patient's decisions such as experience of pain and anxiety related to dental treatment were also investigated. After receiving verbal and written explanations and signed the informed consent form 150 individuals (n=15/group) having the most common type of periodontitis in adults were randomly allocated to be treated in 4 weekly sections or within 24 hours. Oral hygiene instructions and dental debridement were performed alone or in conjunction with antimicrobial agents: a mouth rinse containing chlorhexidine or systemic azithromycin antibiotic tablets. The parameters measured at baseline, 3, 6 and 9 months after treatment were: indicators of inflammation, amount of oral debris and malodor; quantification of bacteria in plaque samples collected with paper points from teeth and tongue; amount of produced saliva and self-reported questionnaires to collect information about oral condition, daily activities, pain and anxiety related to dental treatment.

What is being measured

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

  1. Improvements in pocket depth and clinical attachment level measurements

    Primary outcomes of effectiveness were improvements of the following clinical parameters: periodontal pocket depth (mm) and clinical attachment level (mm) from baseline to 6 months.

    Measured: Changes in pocket depth and clinical attachment level measurements from baseline to 6 months

Secondary outcomes (4)
  1. Improvements in plaque index and gingival index

    Improvements in plaque index (scores) and gingival index (scores) when baseline data was compared to 3 months data.

    Measured: Changes from baseline to 3 months

  2. Maintenance of pocket depth and clinical attachment level measurements

    Pocket depth (mm) and clinical attachment level (mm) values observed at 6 were compared to those observed at 9 months.

    Measured: Changes in pocket depth and clinical attachment level from 6 months to 9 months

  3. Changes in total bacterial load and levels of selected pathogens

    Reductions in total bacterial load and levels of selected pathogens were determined by real time PCR (polymerase chain reaction) in samples from periodontal pockets and dorsal tongue. Values between baseline and 3 months were compared.

    Measured: 3 months

  4. Changes in volume of gingival crevicular fluid and levels of pro-inflammatory cytokines

    Possible reductions in gingival crevicular fluid volume and in concentrations of tumor necrosis factor alfa (TNFα) and interleukin 1 beta (IL-1β) were measured by comparing values between baseline and 3 months.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing FMS full-mouth scaling, QS quadrant scaling and FMS chlorhexidine rinse in people with Periodontitis, run by University of Taubate at 1 site in Brazil.

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 13 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 13 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

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

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Improvements in pocket depth and clinical attachment level measurements (time frame: Changes in pocket depth and clinical attachment level measurements from baseline to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02215460, which also lists 3 linked publications.

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 13 Aug 2014.
