RESUMEN
Abstract: Periodontal diseases are considered a worldwide public health problem, owing to their high prevalence in developed and developing countries. Periodontitis may lead to tooth loss, which can impact oral health-related quality of life. Gingivitis and periodontitis have been extensively studied regarding their etiopathogenesis, epidemiology, prevention and treatment outcomes. However, most of these aspects are studied and discussed globally, which may hamper a clear interpretation of the findings and the design of effective plans of action for specific regions or populations. For example, in Latin America, epidemiological data about the distribution of periodontal diseases is still scarce, mainly when it comes to nationwide representative samples. This Consensus aimed to address the following topics related to periodontal diseases in Latin America: a) The impact of the global burden of periodontal diseases on health: a global reality; b) Periodontal diseases in Latin America; c) Strategies for the prevention of periodontal diseases in Latin America; d) Problems associated with diagnosis of periodontal conditions and possible solutions for Latin America; e) Treatment of Periodontitis. This consensus will help to increase awareness about diagnosis, prevention and treatment of periodontal diseases, in the context of Latin American countries.

Abstract Horizontal bone loss after tooth extraction is a common finding that demands bone reconstruction in various cases. The aim of this study was to assess the horizontal alveolar status in partially and completely edentulous patients using cone-beam computed tomography (CBCT). In total, 1516 CBCT scans of 1404 adult patients were analyzed. Assessment of the images was performed in accordance with the previously published horizontal alveolar change (HAC) classification, which categorizes horizontal bone defects into four classes: HAC 1, HAC 2, HAC 3 and HAC 4 (from the least severe to the most severe condition). Analysis of 1048 scans from partially edentulous patients presented a distribution of 63.55%, 22.14%, 13.36% and 0.95% in HAC 1, HAC 2, HAC 3 and HAC 4, respectively. Analysis of 468 scans from completely edentulous patient images presented a distribution of 19.87%, 28.63%, 41.67% and 9.83% in HAC 1, HAC 2, HAC 3 and HAC 4, respectively. Based on these results, as in HAC 4, no cancellous bone was found between the cortical buccal and lingual/palatal bone plates, it seems reasonable to state that the absence of cancellous bone is higher in completely edentulous patients than in partially edentulous patients. Therefore, the absence of cancellous bone seems to be higher in completely edentulous than in partially edentulous patients.
