In this study texture differentiation associated to bone regeneration properties, around loaded oral implants immersed to Platelets Rich Plasma (PRP), was investigated in panoramic radiographs. The bone-to-implant contact region was analyzed in a follow up clinical sample of 30 digitized panoramic radiographs, 15 corresponding to implant loading (Class I) and 15 after an 8 month period (Class II)...
Intraoral radiographs have been taken to diagnose periapical lesions. Subsequent endodontic treatment needs to be evaluated quantitatively, that is often difficult due to various imaging factors as well as subjective visual interpretation. Therefore, we sought to establish an image analysis based quantitative model to evaluate endodontic treatments (40 effective and 43 noneffective cases). To normalize...
We propose a dental classification system to effectively classify molar teeth from premolar teeth in dental bitewing radiographs. Our system includes a novel image enhancement method that combines homomorphic filtering to reduce the uneven exposure problem, and both adaptive contrast stretching and adaptive morphological transformations to accentuate the texture of gums and pulps. We also propose...
Recent disasters have emphasized the significance of automated dental identification systems. Statistics show that 20% of the 9/11 victims, identified in the first year, were manually identified using dental records. Moreover, 75% of Tsunami victims in Thailand were similarly identified using dental records, compared to 0.5% identified using DNA. This paper addresses the first important problem of...
