About this study

The aim of this prospective interventional study is to verify the efficacy of smoking cessation on clinical and microbiological outcomes of non-surgical periodontal therapy of chronic periodontitis patients. Smokers willing to quit received periodontal treatment and concurrent smoking cessation therapy. Periodontal maintenance was performed every 3 months. A single calibrated examiner, blinded to smoking status, assessed periodontal clinical outcomes and applied a structured questionnaire in order to collect demographic and behavioural information. Further, expired carbon monoxide concentration were measured with a monoximeter. A pooled subgingival plaque sample was collected from the deepest periodontal pocket from each participant. The presence and quantification of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola were determined using (RT-PCR).

Read the detailed description

Smokers willing to quit, with 10 teeth or more, and with periodontitis (30% or more of their teeth with proximal attachment loss ≥ 5 mm) were enrolled in the study. All subjects received periodontal treatment and concurrent smoking cessation therapy. Smoking cessation therapy was performed by a team comprising physicians, nurses, a psychologist and dentists, and consisted of four 1-h counselling lectures, psychologist-assisted cognitive behavioral therapy, nicotine replacement therapy and medication (bupropion or varenicline). Smoking cessation motivation was reinforced by dentists at the maintenance sessions, by means of motivational interviewing techniques. Periodontal therapy consisted in full-mouth supra and subgingival scaling and root planing (with curettes and ultrasonic scaler); oral hygiene instruction and motivation and removal of intra-oral plaque retentive factors. Further, periodontal maintenance was performed every 3 months.

A single calibrated examiner, blinded to smoking status, assessed periodontal clinical outcomes (recession, pocket depth, clinical attachment level, plaque index and bleeding on probing). A structured questionnaire was applied in order to collect demographic and behavioral information. Expired carbon monoxide concentration was measured with a monoximeter, in order to validate smoking status. A pooled subgingival plaque sample was collected from the deepest periodontal pocket from each participant. The presence and quantification of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola were determined using real time - PCR (RT-PCR).

Questions about this trial

What is this clinical trial studying?

A study testing Smoking cessation counseling, Non-surgical periodontal therapy and Nicotine replacement therapy in people with Periodontitis, run by Claudio Mendes Pannuti.

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 3 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 6 Nov 2018. 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: baseline - 12 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 NCT02744417, which also lists 1 linked publication.

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 6 Nov 2018.
