“…Comparing the data to those of reported in other studies involving Brazilian patients with periodontal disease, the frequency of pathogens was lower in the present study (7, 8, 9, 13, 15, 26). However, differences in methodology and distinct population characteristics (ethnic diversity) in the different regions investigated should be stressed.…”

“…In Brazil, few studies have been conducted to investigate the periodontal microbiota and most of these have been carried out in the state of São Paulo (southeastern Brazil) (7, 8, 13, 14, 15, 26). Comparing the data to those of reported in other studies involving Brazilian patients with periodontal disease, the frequency of pathogens was lower in the present study (7, 8, 9, 13, 15, 26).…”

“…In Brazil, few studies have been conducted to investigate the periodontal microbiota, most of these being conducted in the State of São Paulo (7, 8, 9, 13, 14, 15, 26). In these investigations, the bacteria P. gingivalis had its prevalence ranging from 17.8% to 90%, T. forsythia 33.3% to 100%, A. actinomycetemcomitans 23% to 90% and T. denticola was only investigated by Avila-Campos and Velásquez-Meléndez (7) with 60% of positive samples.…”

The aim of the present study was to evaluate the presence of the periodontal pathogens that form the red complex (Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola) and Aggregatibacter actinomycetemcomitans in patients with chronic periodontitis. The sample consisted of 29 patients with a clinical and radiographic diagnosis of chronic periodontitis based on the criteria of the American Academy of Periodontology (3). Samples for microbiological analysis were collected from the four sites of greatest probing depth in each patient, totaling 116 samples. These samples were processed using conventional polymerase chain reaction, which achieved the following positive results: 46.6% for P. gingivalis, 41.4% for T. forsythia, 33.6% for T. denticola and 27.6% for A. actinomycetemcomitans. P. gingivalis and T. forsythia were more prevalent (p < 0.05) in periodontal pockets ≥ 8 mm. The combinations T. forsythia + P. gingivalis (23.2%) and T. forsythia + P. gingivalis + T. denticola (20.0%) were more frequent in sites with a probing depth ≥ 8 mm. Associations with the simultaneous presence of A. actinomycetemcomitans + P. gingivalis, A. actinomycetemcomitans + T. forsythia, P. gingivalis + T. forsythia and T. forsythia + T. denticola were statistically significant (p < 0.05). It was concluded that the red complex pathogens are related to chronic periodontitis, presenting a higher occurrence in deep periodontal pockets. Moreover, the simultaneous presence of these bacteria in deep sites suggests a symbiotic relationship between these virulent species, favoring, in this way, a further progression of periodontal disease.

“…Brazil is the leading Latin American country in research on periodontal microbiology, and A. actinomycetemcomitans in severe periodontal disease has been a particularly important topic of study (Table ). The prevalence of A. actinomycetemcomitans in aggressive periodontitis was found to range between 67% and 80%, with the majority of isolates belonging to biotype X .…”

“…Specifically, black-pigmented bacteria of the Porphyromonas and Prevotella species were detected in subjects with periodontitis (58%), gingivitis (37%) and healthy periodontium (15%) (42). 'Orange complex' pathogens, such as Fusobacterium species (201), and other groups of bacteria, such as Staphylococcus aureus (and even yeasts) may also contribute to chronic periodontitis (27,117). Dental implants can harbor relatively unique bacteria, but may also share the microbiota of periodontitis (71,167).…”

This review article describes the microbiota associated with periodontal disease in Latin America. This vast territory includes 22 nations, which show great ethnic diversity, with large groups of White people, Black people, Mestizo people and Native people. Widespread poverty and limited access to education and health-care services, including periodontal care, are prominent predisposing factors for destructive periodontal disease in Latin America. Black people and Mestizo people seem to have particularly severe periodontal disease and are frequently colonized by the major periodontal pathogens Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. The 'red complex' bacterial pathogens and A. actinomycetemcomitans predominate in chronic and aggressive periodontitis, but gram-negative enteric rods and herpesviruses can also play important periodontopathic roles in Latin America. The key to minimizing the risk of periodontal disease is control of the pathogens, and new low-cost periodontal treatments deserve serious consideration in Latin America.
