Overview of the Interleukin-1 Genetic Test as a Risk Factor for Guiding Effective and Efficient Prevention and Treatment of Periodontitis

2. Chronic Periodontitis is highly prevalent in the adult population and is found in approximately 47% of adults in the U.S. (Eke et al., 2012). Chronic periodontitis is the most common form of periodontitis throughout the world. It should be noted that there are some uncommon forms of periodontitis, grouped together under the name “Aggressive Periodontitis” that are characterized by severe destruction at an early age (childhood in some forms, prior to age 35 in others) and are mostly attributable to major deficiencies in host protective mechanisms, such as neutrophil defects. This overview only concerns Chronic Periodontitis, the common form observed in adults throughout the world.
