Trial summary

Treatment of smoker patients with AgP is considered a challenge to periodontists. To date, only one controlled clinical study (De Genaro Modanese et al., 2016) evaluated the effect of full mouth ultrasonic debridment (FMUD) on smokers with aggressive periodontitis. Read more about this study

About this study

Official title: Influence of Smoking on Clinical, Microbiological and Immunologic Parameters in Patients With Aggressive Periodontitis Treated With Non-surgical Mechanical Therapy Associated With Systemic Antibiotic Therapy.

Treatment of smoker patients with AgP is considered a challenge to periodontists. To date, only one controlled clinical study (De Genaro Modanese et al., 2016) evaluated the effect of full mouth ultrasonic debridment (FMUD) on smokers with aggressive periodontitis. Its results showed significant improvements in clinical parameters (plaque index PI, bleeding on probing- BoP and probing depth-PD), and immunologic (reductions in interleukin 6- IL-6, tumor necrosis factor- α TNF-α levels), although the results were more favorable for non-smoking patients. Antimicrobials associated to mechanical therapy has been extensively studied (Hafajee et al., 2003, Heitz-Mayfield, 2006). The association of Amoxicillin and Metronidazole have had good clinical and microbiological results in randomized clinical trials in the treatment of AgP (Casarin et al., 2012, Sgolastra et al., 2012, Keestra et al., 2015).

Thus, this study investigates clinical, microbiological and immunological influence of smoking in the periodontal debridement associated to Amoxiciclin and Metronidazole of young individuals with pronounced periodontal destruction, compared with non-smokers individuals.

What participants receive

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

  • full mouth ultrassonic debridement associated to Amoxicilin 500 + Metronidazole 400 mgDrug

    The patients were treated by a single-session of periodontal debridement under local anaesthesia during 45 minutes, using an ultrasonic instrument#, using subgengival tips* and irrigation with sterile saline solution, by the same operator (MGC, Paulista University, São Paulo, Brazil). After the debridement, all patients was prescribed with Amoxicillin 500 mg and Metronidazole 400 mg, every 8 hours, for 10 days (Casarin et al., 2012). Subjects were extensively informed about the intake of the prescribed medication. Subjects were clinically and microbiologically monitored at baseline (before therapy) and at 3 and 6 months post-therapy. During the monitored sessions, oral hygiene was evaluated and home care instructions were re-emphasized. Additionally, all subjects were recalled monthly for oral hygiene instructions.

What is being measured

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

  1. Clinical attachment level (CAL) changes at 6 months

    Indicates the distance between the base of the gingival pocket and the cemento-enamel junction, detected with a periodontal probe of 15 mm.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing full mouth ultrassonic debridement associated to Amoxicilin 500 + Metronidazole 400 mg in people with Periodontal Diseases and Aggressive Periodontitis, run by University of Campinas, Brazil 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 4 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 12 Aug 2019. 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. 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?

Results are not available in the source record.

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?

Clinical attachment level (CAL) changes at 6 months (time frame: 6 months). 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 12 Aug 2019.
