Initially, the most common hypothesis was that periodontal infections were caused by a nonspecific overgrowth of bacteria.^40–42 Regardless of the specific types of microorganisms present, the most important factor was the increased amount of bacterial load in the periodontal tissues. Based on this hypothesis, the host would have a defined threshold, and periodontal disease would develop if that threshold became surpassed by increased amounts of bacteria, bacterial byproducts, and virulence factors.⁴³ This theory supports the notion that the most effective method to prevent and arrest disease progression is by the mechanical removal of plaque.
