Image registration plays an important role in the diagnosis of dental pathologies such as dental caries, alveolar bone loss and periapical lesions etc. This paper presents a new wavelet based algorithm for registering noisy and poor contrast dental x-rays. Proposed algorithm has two stages. First stage is a preprocessing stage, removes the noise from the x-ray images. Gaussian filter has been u...

oromandibular dystonia (omd) is a rare focal neurological disorder that affects mouth, face, and jaws. this comprehensive literature review aimed to summarize the current evidence for etiology, diagnosis, and management of omd and assess the possibility of dental origin of the disease and dental treatment plans for these patients. different online databases namely pubmed, google scholar, and sc...

The development of veterinary dentistry has substantially improved the ability to diagnose canine and feline dental abnormalities. Consequently, examinations previously performed only on humans are now available for small animals, thus improving the diagnostic quality. This has increased the need for technical qualification of veterinary professionals and increased technological investments. Th...

INTRODUCTION Aspiration or ingestion of foreign bodies may occur during dental procedures. Diagnosis and management of these accidents is sometimes challenging. The authors present a small series of clinical cases. CASE 1 Adolescent observed due to suspected accidental bracket ingestion, not visible on x-ray, removed by upper digestive endoscopy. CASE 2 Adolescent observed after accidental ...

The Gastro-Esophageal reflux disease (GERD) is a condition resulting from the anatomical and/or functional failure of the containment mechanisms of gastric contents, having as one of its main consequences in the oral cavity dental erosion. The aim of this work is to carry out a showdown between publications that have rated the relationship GERD and dental erosion. Systematic review of the liter...

ABSTRACT Objective: This study aimed to conduct a literature review on self-perception of oral aesthetics in individuals undergoing cosmetic dental treatment and its impact quality life. Methods: 834 articles were found, these, 31 selected accessed from the scientific productions indexed PubMed, LILACS SciELO electronic databases. To rescue sample, following descriptors used Portuguese: estétic...

PURPOSE To determine the MR compatibility of common dental retainer wires at 7 Tesla in terms of potential RF heating and magnetic susceptibility effects. METHODS Electromagnetic simulations and experimental results were compared for dental retainer wires placed in tissue-mimicking phantoms. Simulations were then performed for a human model with wire in place. Finally, image quality was asses...

This paper presents a Dental Based Security System (DBSS), proves to be an equivalent alternative to the Thumb Impression Based Security System (TIBSS) for identifying the persons. The Enhanced Human Identification System using Dental Biometrics (EHISDB) enable content-based retrieval of antemortem (AM) images from the database by comparing the similarity of teeth to postmortem (PM) images. Dur...

This paper presents an analysis on the contrast enhancement function combined with sharpening filter applied on digital Intra-oral dental radiographs images. Intra-oral dental radiograph is a common medium used in dentistry to examine gum related diseases. Due to the fact that radiograph images usually are noisy and low in contrast, research related to image enhancement is an active research ar...
