SUB GINGIVAL COMPLEX MICROBIAL BIOFILMS AND THEIR ERADICATION
Aim of study: The study was conducted to discuss and explain the ability to use a new methods for removal and even prevention of sub gingival biofilm. Biofilm is a three dimensional structure microbial community that first noted in the oral cavity as plaque on the crown of teeth which is called later supra gingival plaque to play a role in caries development . Un eliminated supra gingival plaque grow sub gingivaly to form more protected biofilm found in the gingival sulcus that is responsible for the conversion of physiological gingival sulcus (0-3 mm) to pathological pocket > 3mm which play a role in the pathogenesis of different periodontal infections. Sub-gingival microbiota include mainly anaerobic proteolytic gram negative rods, these microorganisms considered as late colonizer which required the early colonizer to adhere primarily producing specific receptors, reducing the oxidation reduction potential (Eh ), cooperate metabolically within the biofilm. The study was based on a review submitted by: Cortés, et.al. (2011) titled “ Biofilm formation, control and novel strategies for eradication. The study took place during the period (Oct. 2022 - Feb. 2023) The challenges which faces oral microbiologist were characterizing the composition of sub gingival bacterial biofilm since most of them are un cultivable hence new molecular technique were facilitate these difficulties which in turn open horizons for eradication of these resistant microbial biofilm bacterial cells for novel treatment strategies and to prevent recurrence of periodontal infections.
