Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective applicants who conform with inclusion and exclusion criteria will be accepted into the study and sign a consent form.

Visit 1: After initial screening a case report form (CRF) will be filled, including information regarding general health, medication, demographic, oral and dental information. Participants will be clinically examined and the following data will be collected prior to surgery: microbial collection, Plaque score (PS) , probing pocket depth (PPD), bleeding on probing (BOP) at selected non-surgical and surgical teeth. Surgery will be performed followed by discharge with a bottle of chlorhexidine mouthwash and written instructions on its usage. Visit 2: Ten days after surgery sutures will be removed and collected for microbial examination. Microbial collection will be performed at non-surgical and surgical sites. Adverse events will be recorded and participants will be discharged from the study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Microbial identification: periodontal samples will be collected by the GeneFiX™ Saliva DNA Microbiome Collection Device (Isohelix). DNA Extraction - the MagMAX Microbiome Ultra Nucleic Acid Isolation Kits (Termo Fisher). DNA yields and purity - measuring absorbance at 260 nm, A260/A280 and A260/A230 ratios with the Nano-drop 2000 spectrophotometer (Nanodrop products, Wilmigton,USA). Microbiome sequencing - target V4 region of 16s rRNA gene will be sequenced on the Ion Torrent S5 instrument (Thermofisher) and analysis will be performed with the ERGO 2.0 platform ( iGenbio). The investigators will perform comparisons of alpha and beta diversity before and after intervention, as well as differential abundance of the taxa.
