An optimized EBRSA-Bi LSTM model for highly undersampled rapid CT image reconstruction.

COVID-19 has spread all over the world, causing serious panic around the globe. Chest computed tomography (CT) images are integral in confirming COVID positive patients. Several investigations were conducted to improve or maintain the image reconstruction quality for the sample image reconstruction.

Does Age Have a Role in Color and Whiteness Variations After Dehydration and Rehydration in Maxillary Anterior Teeth? An In Vivo Study.

Objective: To determine the influence of in vivo dehydration and rehydration on color and whiteness variations in maxillary anterior teeth of younger, middle-aged, and older individuals.

Methods And Materials: The spectrophotometric shade of maxillary anterior teeth from younger (20 to 30 years, n=20), middle-aged (50 to 60 years, n=20) and older (65 to 80 years, n=20) participants were assessed at baseline and every 10 minutes for 30 minutes after rubber dam isolation (dehydration). The teeth were then allowed to rehydrate, and shade values were assessed every 10 minutes for 30 minutes, after 24 hours, and after 48 hours.

Sensitivity and Specificity of Magnetic Resonance Imaging in Prediction of Cervical Lymph Node Metastasis in Oral Squamous Cell Carcinomas.

Background: The inaccuracies in clinical examination have been well-documented while advanced imaging modalities including computed tomography (CT) and magnetic resonance imaging (MRI) have been shown to have superior diagnostic accuracy in detecting occult and nodal metastasis. The aim of the present study was to identify as well as evaluate the inaccuracies in clinical examination and of clinical diagnostic criteria in known cases of oral squamous cell carcinomas (OSCCs) with the help of MRI.

Methodology: A total of 24 patients attending as outpatients were included in the study while clinically diagnosed and histopathologically proven cases of OSCC were examined clinically and then, subjected to advanced imaging with the help of MRI.

Calcifying Epithelial Odontogenic Cyst of Maxilla: A Clinical and Histological Rarity with Literature Review.

A cyst is defined as a pathological cavity which may or may not have an epithelial lining and which has a fluid, semi-fluid, or gaseous contents and is not formed by the accumulation of pus. The calcifying epithelial odontogenic cyst (CEOC) was first reported by Gorlin et al. in 1962.
