Ibero-Panamerican Federation of Periodontology Delphi study on the trends of periodontology and periodontics by the year 2030. A Latin American consensus.

BACKGROUND AND OBJECTIVE: As elsewhere in the world, the prevalence of periodontitis in stages I-II is high in the Latin American population, this scenario emphasizes the need for identification of urgent needs for allocating adequate resources to provide diagnosis, prevention, and treatment of these diseases. The aim of this Delphi study was to predict the trends in periodontology/periodontics in the Latin American region by the year 2030. METHODS: A steering committee and an advisory group of experts in periodontology/periodontics were selected from 16 countries. An open questionnaire of 60 questions was validated and used following the Delphi methodology. RESULTS: Two hundred and twenty-five experts from Latin America answered the two rounds of the questionnaire. Moderate to strong consensus was reached on 45 questions (75%). The prediction was that the prevalence of gingivitis and periodontitis in stages I and II will be maintained, the importance of the link with systemic diseases will increase, and the impact of prevention and periodontal treatment will also increase, mainly in the private sector. There was a strong consensus that plastic and regenerative surgical procedures will increase, as well as the demand for training in the specialty of periodontology. CONCLUSIONS: The present study has provided relevant and useful information on predictions in periodontology/periodontics in Latin America, with important level of consensus among experts. It has been predicted that periodontitis will still be a highly prevalent disease, and its links with other medical conditions should demand more attention by health authorities to develop adequate prevention and management policies and strategies.

Delphi Project on the trends in Implant Dentistry in the COVID-19 era: Perspectives from Latin America.

AIM: To establish trends in Implant Dentistry in Latin America in the COVID-19 pandemic. MATERIAL AND METHODS: A steering committee and an advisory group of experts in Implant Dentistry were selected among eighteen countries. An open-ended questionnaire by Delphi methodology was validated including 64 questions, divided in 7 topics, concerning the various trends in dental implantology. The survey was conducted in two rounds, which provided the participants in the second round with the results of the first. The questionnaires were completed on August 2020, and the online meeting conference was held on September 2020. The final prediction was developed through consensus by a selected group of experts. RESULTS: A total of 197 experts from Latin America answered the first and second questionnaire. In the first round, the established threshold for consensus (65%) was achieved in 30 questions (46.87%). In the second round, performed on average 45 days later, this level was achieved in 47 questions (73.43%). Consensus was completely reached on the item "Diagnostic" (100%), the field with the lowest consensus was "Demand for treatment with dental implants" (37.5%). CONCLUSIONS: The present study in Latin America has provided relevant and useful information on the predictions in the education and practice of Implant Dentistry in the COVID-19 era. The consensus points toward a great confidence of clinicians in the biosecurity protocols used to minimize the risk of SARS-CoV-2 transmission. It is foreseen as an important change in education, with introduction of virtual reality and other simulation technologies in implant training.

Cambio dimensional, de un hidrocoloide irreversible después de la desinfección de las impresiones con dos marcas comerciales de un glutaraldehido al 2 e hipoclorito de sodio al 0.525 / Dimensional change of irreversible hydrocoloids after impression desinfection with two commercial marks of a glutaldehyde to the 2 per cent and sodium hypochlorite to the 0.525 per cent

El propósito de este estudio fue evaluar los cambios dimensionales ocurridos en modelos de yeso, obtenidos de impresiones con Hidrocoloide irreversible (Kromopan) después de un proceso de desinfección con dos marcas comerciales de glutaraldehído al 2 e hipoclorito de sodio al 0.525 por un tiempo de 10 minutos en inmersión. Se utilizó un grupo control y tres de estudio. Las impresiones se lavaron con agua potable por 10 segundos después de la toma de impresión del modelo maestro y las impresiones de los grupos de estudio fueron llevadas al desinfectante correspondiente por 10 minutos que fueron lavadas nuevamente por 10 segundos. Posteriormente se realizaron los vaciados con yeso tipo III Quik Stone de la casa Whip Mix, con eyuda de un vibrador. Los cambios dimensionales se evaluaron en sentido transversal (A-B), antero posterior (A-C), diagonal (A-D), y de profundidad (E-F) con un calibrador digital de 0.01mm y un micrómetro de profundidad de 0.1mm de precesión (mitutoyo) por una persona con experiencia en esta área. Los resultados se evaluaron mediante el análisis de varianza de una sola vía (ANOVA), se realizó una comparación entre los promedios de los grupos de Glutaraldehido al 2 y el grupo control, según el método de "Boferroni" se demostró que no había cambios dimensionales significativos al utilizar Glutaraldehido al 2 en las impresiones dentales, comparandolas con el grupo control. Al igual que no existen diferencias significativas entre el Vides "y el Microcide GL", en cuanto a cambios dimensionales en el hodrocoloide irreversilble (Kromopan), a diferencia con el Hipoclorito de Sodio que se comparó con el grupo control por medio del test student que evidenció que hay cambios dimensionales significativos.
