RESUMO
If root fractures remain undetected, pulp necrosis will occur in 25% of cases leading to eventual tooth loss. The purpose of this study was to evaluate the diagnostic accuracy of digital phosphor plates using pseudo-color enhancement for detection of horizontal root fractures in single-rooted teeth. Eighty-two human single-rooted teeth were evaluated [41 with no horizontal fracture and 41 with horizontal fractures]. Digital intraoral imaging plate system. [Digora[registered sign] Optime PSP System, Soredex] was used to obtain 16-bit gray scale images. Five 16-bit images were obtained from each specimen and saved [one original and four with pseudo-color enhancement]. Four observers evaluated the images twice with a 2- week interval. Accuracy, positive predictive value [PPV], negative predictive value [NPV], specificity and sensitivity for each observer and each image group were calculated. The diagnostic sensitivities were not significantly different among the five images [P absolute=0.125, P complete=0.170]. But, statistically significant differences were found in the diagnostic specificity [P absolute=0.019, P complete=0.016] among the five views. Cool and Summer views had higher diagnostic specificity than Bone, Copper and Original views [P=0.025]. Kappa and Weighted Kappa values showed statistically significant differences for intra- and inter-observer reliability in the five views [P=0.032]. Both Cool and Summer views were suitable for detection of horizontal root fractures and had statistically significant differences with the original view
RESUMO
Ellis - van Creveld syndrome [EVC] or chondroectodermal dysplasia, a rare autosomal recessive disorder, is a tetrad of chondrodysplasia, ectodermal dysplasia, polydactly, and congenital heart disease, that frequently presents with the single atrium defect. Chondrodystrophy of the tubular bones is the most common feature, while central nervous system [CNS] and urinary tract anomalies are very rare. The reported case is a 2800 gr female neonate with polydactyly of fingers, short limbs, deformed chest, single atrium and cystic kidney
