Description
Summary:The gingival recession was assessed in 380 adult individuals aged more than 20 years and comprised both subjects being treated and looking for treatment at Bauru Dental School. Clinical evaluation was conducted by a single examiner in all teeth and involved analysis of four dental aspects (mesial, buccal, distal and lingual). The gingival recession was regarded as present whenever more than 1mm of root surface was exposed, and its vertical width was measured in millimeters from the cementoenamel junction to the gingival margin. The recessions were further scored following the criteria suggested by Miller in 1985. Gingival recession was observed in at least one dental surface in about 89% of the individuals analyzed. The prevalence, extension and severity of this clinical aspect increased with age. Class I recessions were the most frequent, yet there was a gradual increase of Class III and IV recessions as older subjects were evaluated. The mandibular teeth displayed more surfaces with gingival recession than the maxillary teeth and the mandibular incisors were the most affected teeth. Such high prevalence of gingival recession in adult patients demonstrates that dental professionals should provide attention to the clinical relevance of such alterations, as well as to the diagnosis of the etiologic factors.<br>Recessão gengival foi relatada em 380 indivíduos adultos com mais de 20 anos de idade, pacientes em tratamento ou indivíduos que procuravam atendimento odontológico na Faculdade de Odontologia de Bauru. Durante avaliação clínica, realizada por apenas um examinador, em todos os dentes, quatro superfícies foram consideradas (mesial, vestibular, distal e lingual). Recessão gengival foi considerada presente quando mais de 1mm de raiz estivesse exposta e sua amplitude vertical foi medida em milímetros da junção cemento-esmalte a margem gengival. As recessões foram ainda classificadas segundo os parâmetros da classificação proposta por Miller, em 1985. Recessão gengival foi encontrada em pelo menos uma superfície dentária em aproximadamente 89% dos indivíduos avaliados. A prevalência, extensão e severidade desta condição clínica aumentaram com o avanço da idade. As recessões classe I foram as mais freqüentes, mas houve um aumento gradual das recessões classe III e IV à medida que indivíduos mais idosos foram avaliados. Os dentes inferiores tiveram mais superfícies com recessão do que os superiores, e os mais freqüentemente envolvidos foram os incisivos inferiores. Diante da elevada prevalência de recessão gengival em adultos, os cirurgiões-dentistas devem estar atentos à importância clínica destas alterações e ao diagnóstico de seus fatores causais.
