Article endobj The definition of dental caries has expanded to a more complex discussion of the caries process that represents a continuum of tooth demineralization/remineralization. Digital radiographic sensors are an objective and reproducible technique; however, its sensitivity for detection of early and recurrent caries is suboptimal, , with reported sensitivity being as low as 0.30. , Caries detection can be affected by a variety of factors during acquisition or interpretation, such as variation in image capture, detector placement, status of the detector, focus to object distance, kilovolt or milliampere used for capture of the radiograph, ambient lighting for interpretation, or the experience of the clinician. 4 0 obj Syst.

Article Scientific Reports (Sci Rep) Use the green screen, along with Zoom, when you need a virtual background in your video. Some of the inclusion and exclusion criteria used in the systematic review may have limited the evidence supporting the use of radiography, especially for the diagnosis of proximal surface caries. Bitewing radiographs show an increased density of the bone under the pontic (green arrows). Dental radiographs are part of the dental record therefore, they are: Legislature sends laws to the state board of dental examiners who write laws to rules & regulation. Kaye, E. et al.

At least 2 major groups of bacteria, namely, the streptococci species (chiefly Streptococcus mutans ) and the Iactobacilli species (chiefly Lactobacillus fermentum , Lactobacillus casei/paracasei , and Lactobacillus salivarius ), can produce organic acids during metabolism of fermentable carbohydrates and are known as acidogenic. Uprichard KK, Potter BJ, Russell CM, Schafer TE, Adair S, Weller RN. 2 ) and are used in clinical practice to evaluate interproximal caries; crestal bone height in the interproximal region; calculus; and periodontal disease. The line pair resolution of digital dental radiographs is about 20 line pairs per millimeter. 2003-2023 Chegg Inc. All rights reserved. At the time the article was created Henry Knipe had no recorded disclosures. Today, dental caries is accepted as an imbalance in the biofilm-induced cyclic process of demineralization and remineralization of tooth structure, by the acidic by-products resulting in a pH maximal drop followed by the return of the pH to initial pH modulated by saliva. Using the " E" speed film can reduce the radiation exposure to the patient by: Steam autoclave, chemical vapor, & dry heat.

Although considerable attention has been placed on a few bacterial species as the cause of dental caries (eg, S mutans , Lactobacillus ), there is general agreement today that the dental biofilm exists as a complex ecosystem that can shift from a neutral pH to a more acidic ecosystem. 5, CD003879.

IEEE Trans. Because radiographs are a 2-dimensional representation of a 3-dimensional tooth structure, it is not always possible to determine caries extension to the pulp chamber or pulp horn because of anatomic variations and presence of radiopaque restorations in the crowns. Lee, H. & Song, J. Which of the following anatomical structures would appear radiopaque on a processed . stream Dentin is located deep to the enamel and cementum and is isoattenuating relative to the cementum and hypoattenuating relative to the enamel. A drain must be sufficiently opaque to x-rays to be easily seen in any part of the body. All radiographic images are not created equal. Darkroom infection control guidelines may include: Films should be handled as little as possible, preferably the edges, handle processed films with clean hands, and after all films are I'n processor wash & dry hands. stream Appropriate kilovolt and milliampere as well as standardized exposure time are essential for optimally exposed radiographs.
