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.
