Study summary

This study will assess clinical and microbiological efficacy of probiotics and antibiotics in patients of chronic periodontitis as an adjunctive to scaling and root planing (SRP) in reducing bacterial count and in improving clinical periodontal parameters over the period of 12 weeks.Also the comparison between these adjunctives will be made for clinical assessment clinical periodontal parameters will be taken .these parameters plaque index (PI), gingival index (GI), clinical attachment loss (CAL) and pocket probing depth (PPD) for microbiological assessment plaque sample will be taken, DNA will be extracted and then sample will be processed through quantitative polymerase chain reaction (qPCR) for quantitative analysis of bacterial count of porphyromonas gingivalis.

Read the detailed description

In this clinical trial total 60 participants of clinically diagnosed chronic periodontitis will be recruited after taking a written consent for their approval. Participants will be divided into 3 groups A, B and C through the process of randomization using a method of opaque sealed envelopes. A research assistant will be hired for the purpose of randomization and allocation concealment. All participants will be asked to pick an opaque envelope containing the details of treatment products. After randomization plaque sample will be obtained from the depth of periodontal pockets and all the clinical periodontal parameters will be recorded in every participant. Then all the participants will undergo SRP. After SRP group A will be given antibiotics Amoxicillin 500 milligrams (mg) for 3 times a day (TDS) and Metronidazole 400 milligrams (mg) for twice a day (BD) for 5 days. Group B will be given probiotics lactobacillus reuteri 1.2 billion colony forming unit (CFU) sachets twice daily for swallowing with water for 12 weeks. Group C will be given lactobacillus sachets of same amount and participant will be asked to mix it with little amount of water and apply it on teeth with the toothbrush twice daily after brushing with standard tooth paste for 12 weeks. Patients will be recalled at the interval of 3, 6, 9 and 12 weeks for the recording of clinical periodontal parameters. After completion of trial plaque sample will be taken again from every participant and will be processed through qPCR to check bacterial count of porphyromonas gingivalis before and after treatment. Whereas comparison between clinical periodontal parameters will be made at the interval of 0, 3, 6, 9, 12 weeks.

What researchers measure

Primary outcomes

  1. Change in periodontal pocket depth (PPD)

    It is the distance from tip of free gingival margin to the base of pocket

    Time frame: Baseline, 3, 6, 9 and 12 weeks

  2. Change in clinical attachment level (CAL)

    It is the distance from cementoenamel junction to the base of the pocket around the tooth

    Time frame: Baseline, 3, 6, 9 and 12 weeks

  3. Change in bacterial load of Porphyromonas gingivalis

    Bacterial count or the quantity of porphyromonas gingivalis in the sample

    Time frame: Baseline and 12 weeks after completion of trial

Secondary outcomes

  1. Change in the Plaque index (PI)

    How much surface of tooth is covered by the plaque will be recorded.

    Time frame: Baseline, 3, 6, 9 and 12 weeks

  2. Change in Gingival index (GI)

    Gingival color texture and inflammation will be recorded.

    Time frame: Baseline, 3, 6, 9 and 12 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in Sep 2018, 10 months.

Of 88 non-industry interventional studies with no phase under Chronic Periodontitis, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 24. This study's 10 months is below that.

Counting every sponsor, half of 89 studies reached it within 15 months; a quarter within 10 and three quarters within 24.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 12, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
