Resumo
Foram analisados 100 dentes primeiros molares e 100 dentes segundos molares superiores, direitos e esquerdos, permanentes, extraídos de humanos, com o objetivo de explorar a região anatômica da furca, mais especificamente realizar medidas das distâncias das aberturas das furcas vestibular, mesial, e distal até à junção esmalte-cemento, e das distâncias das referidas aberturas até às faces radiculares pertinentes: vestibular, mesial, distal e lingual. Utilizou-se para mensuração um microcomputador 486 DX-66Mhz, no qual estava instalado um software analisador de imagens Mocha-Jandel Scientific SigmaScan Pro, version 2.0. Em relação às distâncias das aberturas das furcas até à junção esmalte-cemento foi observado que as distâncias médias para a furca vestibular foram de 3,50mm e 3,03mm; para a furca mesial de 4,44mm e 4,69mm; para a furca distal de 4,26mm e 3,73mm, respectivamente para os primeiros e segundos molares superiores. Em relação às distâncias das aberturas das furcas até às faces radiculares pertinentes foi observado que as distâncias médias da furca vestibular até à face mesial da raiz mesio-vestibular foram de 3,78mm e 3,72mm; da furca vestibular até a face distal da raiz disto-vestibular 3,62 e 3,64mm; da furca mesial até à face vestibular da raiz mesio-vestibular 7,33mm e 6,89mm; da furca mesial até a face lingual da raiz lingual de 4,13mm e 4,33mm; da furca distal até à face vestibular da raiz disto-vestibular de 5,61mm e 5,09mm; da furca distal até a face lingual da raiz lingual de 4,73mm e 4,65mm, respectivamente para os primeiros e segundos molares superiores.
Two hundred teeth were analysed, out of which 100 were first molars and 100 were second molars, extracted from humans, aiming the examination of the furcal anatomical region, more specifically the measurement of the distances from the buccal, mesial and distal furcal openings.to the cement-enamel junction, and the distances from the quoted openings to the bucal, mesial, distal and lingual root faces. It was made use of a 486 DX-66Mhz personal computer, in which a Mocha-Jandel Scientific SigmaScan Pro image software, version 2.0, was installed. In relation to the distances from the furcal openings to the cement-enamel junction, it was observed that the average distances for the bucal furcal were 3.50 mm and 3.03mm, for the mesial furcal , 4.44mm and 4.69mm; for the distal furcal, 4.26mm and 3.73mm, for the first and second maxillary molars, respectively. In relation to the distances from the furcal openings to the radicular faces , it was observed that the average distances from the bucal furcal to the mesial face of mesio-vestibular root were 3.78 mm and 3.72mm; from the bucal furcal to the (face distal da raiz disto-vestibular), 3.62mm and 3.64mm; from the mesial furcal to the buccal face of the mesio-vestibular root, 7.33mm and 6.89 mm; from the mesial furcal to the lingual face of the lingual root, 4.13mm and 4.33mm; from the distal furcal to the bucal face of the disto-vestibular root, 5.61mm and 5.09mm; from the distal furcal to the lingual face of the lingual root, 4.73mm and 4.65mm, for the first and second maxillary molars , respectively. Keywords: Molar; Molar - Radicular Faces; Molar - Average Distances; Radicular Furcal.
