Fractal dimension analysis in digital periapical radiographs: A diagnostic indicator of osteoporosis in post-menopausal women

Image enhancement of digital periapical radiographs according to diagnostic tasks

PURPOSE This study was performed to investigate the effect of image enhancement of periapical radiographs according to the diagnostic task. MATERIALS AND METHODS Eighty digital intraoral radiographs were obtained from patients and classified into four groups according to the diagnostic tasks of dental caries, periodontal diseases, periapical lesions, and endodontic files. All images were enha...

Evaluation of panoramic Radiographs as a Screening Tool of Osteoporosis in Post Menopausal Women: A Cross Sectional Study.

BACKGROUND Indian women, especially those from low-income groups consume diets that are deficient of calcium, proteins and micronutrients. Hence, they are prone to suffer from osteoporotic hip fractures at a much earlier age than western women. To detect early signs of osteoporosis, it is ideal to perform Bone Mineral Density testing of all post-menopausal women who are at risk. AIM (i) To as...

Hypomethylation of Alu Elements in Post-Menopausal Women with Osteoporosis

A decrease in genomic methylation commonly occurs in aging cells; however, whether this epigenetic modification leads to age-related phenotypes has not been evaluated. Alu elements are the major interspersed repetitive DNA elements in humans that lose DNA methylation in aging individuals. Alu demethylation in blood cells starts at approximately 40 years of age, and the degree of Alu hypomethyla...

Estimation of fractal dimension in radiographs.

In the last decade, the fractal dimension has become a popular parameter to characterize image textures. Also in radiographs, various procedures have been used to estimate the fractal dimension. However, certain characteristics of the radiographic process, e.g., noise and blurring, interfere with the straightforward application of these estimation methods. In this study, the influence of quantu...
