A Latin American perspective of periodontology.

Periodontal diseases occur worldwide, and Latin American populations are significantly affected by different manifestations of periodontal disease. The interest in periodontics and periodontal therapy first developed in the early 1930s in the southernmost countries of Latin America, and spread, as the years went by, throughout the region. Today, periodontal research is vibrant in Latin America. The aim of this volume of Periodontology 2000 was to present an overview of the periodontal research currently being performed in different countries of Latin America. The epidemiology of periodontal diseases in adults, children and adolescents, and the pathogenesis of such diseases (including microbiological characteristics and risk factors), are discussed. The role of systemic antibiotic therapy and the effect of smoking are discussed in relation to the progression and the treatment of periodontitis. In addition, the benefit of lasers in periodontal therapy is evaluated. Latin American research groups have been active in exploring new venues of regenerative periodontal treatment, addressing the role of cementum proteins, growth factors and oral mesenchymal stem cells in tissue engineering. Finally, basic research to study cancerization is reported.
