Introdução: A maioria dos europeus idosos terá mais dentes naturais, e por isso haverá um aumento de vários problemas orais, entre os quais a exposição da dentina cervical. A dentina é o maior componente estrutural do dente humano. Objetivo: Rever o “estado da arte” relativamente à evolução ao longo do tempo do compartimento mais dinâmico, a dentina intratubular. Método: Realizou-se uma revisão narrativa da literatura, durante o período compreendido entre 2009-2019, nos motores de busca “dentin“, “ aging” , “ intratubular dentin”, “sclerotic dentin” e ” dentin permeability”. Desenvolvimento: A estrutura dentinária é submetida a alterações fisiológicas e histológicas com o passar do tempo, nestas incluem-se: aumento da espessura, diminuição da densidade dos Odontoblastos, aumento da mineralização no compartimento intratubular e obliteração dos túbulos dentinários. Conclusões: O impacto das alterações da dentina intratubular, não é um assunto completamente esclarecido, mas assume na literatura uma importância crescente, com implicações clínicas importantes.
Introduction: Most older Europeans will have more natural teeth, and so there will be an increase in several oral problems, among which cervical dentine exposure. Dentin is the largest structural component of the human tooth. Objective: To review the "state of the art" regarding the evolution over time of the most dynamic compartment, the intratubular dentine. Method: A literature review was performed during the period 2009-2019 on the "dentin", "aging", "intratubular dentin", "sclerotic dentin" and "dentin permeability" search engines. Development: The dentin structure undergoes physiological and histological changes with the passage of time. These include: thickening, decrease in Odontoblast density, increased intratubular compartment mineralization and obliteration of dentinal tubules. Conclusions: The impact of intratubular dentin changes is not a fully understood subject, but it is increasingly important in the literature with important clinical implications.
