What's new about molecular diagnostics and periodontal disease?

Culture techniques have been traditionally used to identify periodontal disease bacterial species in subgingival samples. But several problems were frecquent. The vast majority of species are anaerobe, so special techniques have to be employed, and are laborious and require long periods of time. They involve to mantain alive cells from samples, so many of them can die during transport to laboratory.

PCR based molecular diagnostics allows to detect any bacterial species within hours, and this technique does not require alive cells, so its sensitivity is much better, and prevalence of bacteria more real.
