[Evaluation of the diagnostic efficacy of intra oral digital radiography with and without zoom option software in the detection of occlusal dentinal caries: an in vitro study]

The purpose of this study was to evaluate the diagnostic precision of zoom option of Cygnus Ritter CCD intraoral digital sensor compared to original digital radiography in the detection of occlusal dentinal caries. Eighty-six extracted premolars with no apparent clinical caries were selected. Two methods were used for radiography; namely, digital radiography using a Cygnus Ritter CCD sensor and then zoom option was applied to the original radiographs. Four maxillofacial radiologists observed the original digital and the same radiographs with zoom option to detect occlusal dentinal caries subsequently recording it in a five-grade scale. Microscopic sections evaluated by a pathologist were used as the gold standard for caries detection. The data were analyzed with a proportion test and processed with SPSS maxillofacial 14 soft ware. Statistical analysis showed a sensitivity of 52.2% [71] [CI: 95%] for zoom option in the detection of occlusal dentinal caries [P<0.05]. The specificity was shown as 68.8% [143] [P>0.05]. The ppv was calculated as 52.2% [179] [P<0/.05] and npv as 68.8% [236] [P<0.05] and the accuracy was 62.2% [214] [P<0.05]. The zoom option of Cygnus Ritter CCD sensor showed a significantly higher diagnostic sensitivity, ppv, npv and accuracy compared to original digital radiographs, but the zoom option of that sensor did not show a significantly higher diagnostic specificity compared to original digital radiographs

Cyclopia with polydactyly and congenital heart disease in one of discordant twins: acase report

Cyclopia is a rare congenital abnormality consisting of fused orbits and a single eye and is the most extreme form of alobar holoprosencephaly. It is an uncommon congenital anomaly resulting from arrest of the development of the anterior end of the neural plate. It is always associated with abnormalities of the brain. In one study, cyclopia was reported in one discordant twin only[1]. In this report, we describe a case of cyclopia that was associated with ploydactyly and congenital heart disease in a female infant who was one of discordant twins
