Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Summary

Detecting secondary caries around dental restorations is crucial. Quantitative light-induced fluorescence (QLF) and Fluorescence Enamel Imaging (PCDS) show promise for composite resins, but methods are questionable for amalgam restorations.

Area of Science:

Dental operative dentistry
Caries detection technologies
Restorative dentistry

Background:

Secondary caries is a primary cause for replacing dental restorations.
Advanced diagnostic tools can improve the accuracy of secondary caries detection.
This study assesses new methods for identifying secondary caries around amalgam and composite restorations.

Purpose of the Study:

To evaluate the performance of visual criteria (International Caries Detection and Assessment System - ICDAS) and optical devices for detecting secondary caries.
To compare these methods around amalgam and resin composite restorations in permanent teeth.

Main Methods:

180 extracted teeth with Class I amalgam (n=90) and resin composite (n=90) restorations were analyzed.
Examiners used ICDAS visual criteria, laser fluorescence (LF), light-emitting diode (MID), quantitative light-induced fluorescence (QLF), and Fluorescence Enamel Imaging (PCDS).
Confocal laser scanning microscopy served as the gold standard for diagnosis.

Main Results:

All tested methods demonstrated high reproducibility, except for MID around amalgam restorations.
QLF and PCDS exhibited the highest sensitivity for detecting secondary caries in both groups.
Other methods showed superior specificity (p < 0.05).

Conclusions:

The MID device was not effective for secondary caries detection around either restoration type.
ICDAS, LF, QLF, and PCDS showed potential for detecting secondary caries around resin composite restorations.
The effectiveness of all evaluated methods for secondary caries detection around amalgam restorations remains questionable.
