Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

The present randomized controlled clinical trial was conducted to evaluate the effects of Lactobacillus reuteri-containing probiotic suspension as an adjunct to scaling and root planing (SRP).

Material and Methods: Twenty sites from twelve chronic periodontitis patients were recruited and monitored clinically and microbiologically at baseline, three, and six months after therapy for plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment level (CAL) and microbiologically or Porphyromonas gingivalis (P. gingivalis) load. Patients meeting the inclusion criteria were scheduled within one week for two sessions of SRP performed using ultrasonic scalers and hand instrumentation. After SRP, oral hygiene measures were reassured and then sites were randomly allocated to one of the two groups 10 sites each. group I (SRP only) and group II (SRP + probiotic). Group II received SRP and sub-gingival delivery of 1ml of probiotic L. reuteri suspension at baseline (immediately after SRP), one, two and four weeks using blunt syringe. Periodontal dressing was applied after placement of the drug.

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.

Ages Eligible for Study

31 years to 51 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients with good systemic health.
  2. Patients with moderate chronic periodontitis with attachment level ranging from 3-4 mm.
  3. Optimal compliance as evidenced by no missed treatment appointments and positive attitude towards oral hygiene.
  4. No gingival recession.

Exclusion Criteria:

  1. Patients with history of antibiotic, anti-inflammatory drugs or periodontal therapy in the preceding 6 months.
  2. Patients with risk factors (e.g. - smoking, uncontrolled diabetes, uncontrolled hypertension, pregnant or any other systemic disease which can alter the course of periodontal therapy).
  3. Patients who are allergic to lactate products.

Active Comparator: Probiotic group

patients received SRP and by using blunt syringe, subgingival delivery of 1ml of probiotic suspension was applied to these sites at baseline (immediately after SRP), one, two and four weeks. Periodontal dressing was applied after placement of the drug.

After placement of the drug, patients were instructed to keep away from chewing hard or sticky food, brushing near the treated areas, or using any interdental aids for 24 hours.

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
Change in Probing pocket depth
Time Frame: Baseline. 3 months. 6 months
Individual acrylic stents were prepared to serve as the constant points to align the probe consistently and to reduce errors associated with probe placement. Probing pocket depth was assessed using a manual probe (UNC-15). The distance from the free gingival margin to the bottom of the pocket was recorded at six sites for each examined tooth. The probe was inserted in line with the long axis of the tooth and walked circumferentially around each surface of each tooth to detect and record the area of the deepest probe penetration. The mean probing pocket depth was obtained by summing the scores for the six sites and dividing it by six.
Baseline. 3 months. 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
Change in Plaque index
Time Frame: Baseline, 3 and 6 months
This index distinguishes clearly between the severity and the location of soft debris aggregates.
Baseline, 3 and 6 months
Change in Bleeding on probing
Time Frame: Baseline, 3 and 6 months
Bleeding on probing was performed through gentle probing of the orifice of the gingival crevice. If bleeding occurs within 10 seconds, the number of positive sites is recorded and then expressed as a percentage of the number of sites examined.
Baseline, 3 and 6 months
Change in Clinical attachment level
Time Frame: Baseline, 3 and 6 months
The distance from cementoenamel junction to the bottom of the pocket was measured in the same way as described for probing
Baseline, 3 and 6 months
