There is little material in the literature that compares biological width measurements in periapical and bite-wings radiographs with clinical measurements. The purpose of this study was to compare measurements of biological width taken by three different methods which are frequently used for planning periodontal surgery -periapical radiograph, bite-wing radiograph and transperiodontal probing -with the trans-surgical measurements. Thirty-four sites from twenty-one subjects were analyzed. The intra-class correlation coefficients between measurements obtained trans-surgically (gold standard) and those obtained by transperiodontal probing, periapical radiography and bite-wing radiography were determined. Average measurements were compared using the Wilcoxon test at a significance level of 0.05. Also, the frequency distribution of differences between test measurements and the gold standard was calculated. The results showed that transperiodontal probing (mean 2.05 mm) was the most accurate measurement, as compared to the gold standard (mean 1.97 mm), with no statistically significant difference observed. On the other hand, periapical and bite-wing radiographic mean values (1.56 mm and 1.72 mm, respectively) were smaller than the gold standard, with statistically significant differences (p < 0.05). It was concluded that transperiodontal probing was the most accurate measurement, as compared to the gold standard, followed by that obtained with the bite-wing radiograph. The clinical relevance of these results could be that planning for crown lengthening surgery should, preferably, include transperiodontal probing.
A medida da amplitude do movimento é um importante parâmetro utilizado na avaliação e no acompanhamento fisioterápico. Portanto, a confiabilidade destas medidas e dos instrumentos utilizados para esta finalidade deve ser avaliada. Objetivo: Avaliar e comparar a confiabilidade intra-examinador e interexaminador da medida de amplitude do movimento (ADM) de dorsiflexão ativa do tornozelo utilizando um goniômetro universal e um inclinômetro digital. Métodos: Dois estudantes avaliaram a amplitude de dorsiflexão de 28 voluntários com idade entre 18 e 30 anos utilizando um inclinômetro digital e um goniômetro universal. Resultados: Os resultados demonstram média e desvio padrão da amplitude do movimento de 18,1±3,1 e 18,6±3,8 graus para as medidas obtidas pelo goniômetro e inclinômetro, respectivamente. O coeficiente de correlação intraclasse (CCI) encontrado para a condição na mesma sessão para as medidas obtidas com o inclinômetro foi de 0.91 e 0.83, para os examinadores A e B, respectivamente. Já o CCI obtido pelo goniômetro foi de 0.91 e 0.97 para os examinadores A e B, respectivamente. Os resultados da confiabilidade entre as sessões de teste demonstraram confiabilidade moderada para as medidas de goniometria e alta confiabilidade para a inclinometria. Já a confiabilidade interexaminador foi moderada para as medidas obtidas pelo goniômetro e alta para as medidas obtidas pelo inclinômetro. Conclusão: Os resultados do presente estudo demonstraram uma maior confiabilidade para as medidas de amplitude de movimento obtidas pelo inclinômetro digital quando comparado com o goniômetro universal, principalmente quando a confiabilidade interexaminador foi avaliada.
