About this study

Official title: Effect of Antibiotic and Probiotic Therapies in the Adjuvant Treatment of Chronic Periodontitis: Randomized Controlled Clinical Trial.

Currently, with the increase of bacterial resistance to antibiotics associated with its side effects, it is necessary to find other adjuncts to combat the disease that are an alternative to the use of antibiotics. The use of probiotics has been proposed in the literature as an adjunct therapy for the treatment of periodontal diseases, however, few controlled and randomized clinical studies have been performed. The objective of this double-blind randomized controlled trial will be to evaluate the response of clinical and microbiological periodontal parameters to the comparison of two different adjuvant therapies (antibiotic and probiotic) for the treatment of stages II and III grade B periodontitis.

Currently, with the increase of bacterial resistance to antibiotics associated with its side effects, it is necessary to find other adjuncts to combat the disease that are an alternative to the use of antibiotics. The use of probiotics has been proposed in the literature as an adjunct therapy for the treatment of periodontal diseases, however, few controlled and randomized clinical studies have been performed. The objective of this double-blind randomized controlled trial will be to evaluate the response of clinical and immunological periodontal parameters to the comparison of two different adjuvant therapies (antibiotic and probiotic) for the treatment of stages II and III grade B periodontitis. Patients will be randomized into 3 groups: Group 1 (n=15): periodontal debridement, Group 2 (n=15): periodontal debridement associated with antibiotic (Metronidazole 400 mg + Amoxicillin 500mg) and Group 3 (n=15): periodontal debridement associated with probiotic (Lactobacillus reuteri). Clinical (plaque index, gingival index, probing depth, gingival recession, relative clinical attachment level and periodontal inflamed surface area (PISA) index) and immunological data obtained before and after periodontal therapy (baseline, 30 and 90) will be consolidated and made available on average ± standard deviation and normality tested using the Shapiro-Wilk test. For statistical analysis, the software BioEstat 5.0 (Belém, PA, Brazil) will be used, with p-value < 0,05.

What participants receive

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

  • Placebo Oral TabletDrug

    Also called Periodontal debridement

    Non-surgical periodontal treatment will be performed by means of periodontal debridement in a single session.

  • Amoxicillin 500 MgDrug

    Also called Metronidazole Oral

    Non-surgical periodontal treatment will be performed by means of periodontal debridement in a single session after the therapy will be administered the antibiotic (Metronidazole 400mg + Amoxicillin 500mg) every 8 hours for 7 days

  • Lactobacillus reuteri Oral DropsDrug

    Also called Prodentis

    Non-surgical periodontal treatment will be performed by means of periodontal debridement in a single session after the therapy will be administered the probiotic (Lactobacillus reuteri oral drops ) twice a day for 21 days.

What is being measured

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

  1. Probing Depth change

    The change in the probing depth will be measure in millimeters before and after the treatment.

    Measured: Baseline, 30 and 90 days

Secondary outcomes (6)
  1. Plaque Index

    Number of teeth affected before and after periodontal treatment.

    Measured: Baseline, 30 and 90 days

  2. Gingival Index

    Number of teeth affected before and after the treatment.

    Measured: Baseline, 30 and 90 days

  3. Gingival Recession

    Evaluated in milimeters before and after the treatment.

    Measured: Baseline, 30 and 90 days

  4. Clinical Attachment Level

    Evaluated in milimeters before and after the treatment.

    Measured: Baseline, 30 and 90 days

  5. Periodontal Inflamed Surface Area (PISA)

    Is calculated from data collected on probing the periodontal pocket and are placed in a table which gives the value of the periodontal inflamed surface area.

    Measured: Baseline, 30 and 90 days

  6. Microbiological Parameters

    crevicular fluid samples will be analyzed by PCR (real time PCR) for detection and quantification of: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Lactobacillus reuteri.

    Measured: Baseline, 30 and 90 days

Questions about this trial

What is this clinical trial studying?

A study testing Amoxicillin 500 Mg and Lactobacillus reuteri Oral Drops in people with Chronic Periodontitis Complex, run by Universidade Estadual Paulista Júlio de Mesquita Filho 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 5 inclusion and 6 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 17 Nov 2020. 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?

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?

Probing Depth change (time frame: Baseline, 30 and 90 days). 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 17 Nov 2020.
