ABSTRACT
ABSTRACT The low prevalence of gingival recessions observed in orthodontic clinical practice may be assigned to the fact that in studies in which dehiscences and bone fenestrations are described as frequent, they were diagnosed based on 1) dry skull studies; 2) areas with periosteal reflection together with flap; and 3) imaging techniques with low sensitivity to detect these defects, which have a delicate structure and function. In areas of pseudo-dehiscences and fenestrations, the periosteum and the alveolar cortical bone are very thin; also, they either have been removed during preparation of the dry specimens in the areas for analysis, or, alternatively, have not been investigated using an ideal imaging method.
RESUMO
RESUMO A ausência de prevalência elevada das recessões gengivais relacionadas à prática clínica ortodôntica se explica, provavelmente, porque, nos trabalhos em que as deiscências e fenestrações ósseas são descritas como frequentes, essas foram diagnosticadas a partir de 1) estudos em crânios secos; 2) áreas com rebatimento periosteal junto com o retalho; e 3) uso de métodos imagiológicos que falham em sensibilidade para captá-las, pela sua delicadeza estrutural e funcional. Nessas áreas de pseudodeiscências e fenestrações, existe periósteo e cortical óssea alveolar muito fina, que foram eliminados nos procedimentos de preparação dos espécimes secos, nas áreas para a análise ou, então, não se aplicou um método imagiológico ideal.
