Verification of accuracy of an algorithmic image-based dental pulp vitality test

Medical Imaging 2020: Computer-Aided Diagnosis, 2020
Background: Endodontic maladies incur significant costs to the military and are difficult to diagnose. Early identification and treatment of endodontic conditions are critical. Our research focused on designing a novel, vitality-based photoplethysmography imaging (PPGI) system capable of determining the pulse frequency within the dental pulp, allowing ...

Evaluation of Accuracy, Reliability, and Repeatability of Five Dental Pulp Tests

Journal of Endodontics, 2011
The aim of this study was to compare the clinical accuracy, reliability, and repeatability of laser Doppler flowmetry (LDF), an electric pulp test (EPT), and various thermal pulp sensibility tests.Pulp tests were done on 121 teeth in 20 subjects by using LDF, EPT, and thermal pulp testing (CO(2), Endo Frost [EF], Ice) during 2 or 3 test sessions with ...

Predictive Values of Thermal and Electrical Dental Pulp Tests: A Clinical Study

Journal of Endodontics, 2013
For a diagnostic test to be useful, it is necessary to determine the probability that the test will provide the correct diagnosis. Therefore, it is necessary to calculate the predictive value of diagnostics. The aim of the present study was to identify the sensitivity, specificity, positive and negative predictive values, accuracy, and reproducibility ...

Does dental fluorosis affect electric pulp test response and/or optimum probe placement site?

Australian Endodontic Journal, 2021
AbstractThe placement site of electric pulp tester (EPT) probe on the tooth affects the threshold values obtained. The aim of this study was to determine and compare threshold levels and appropriate placement sites for EPT probe on fluorotic and normal teeth.

Diagnostic Accuracy of 5 Dental Pulp Tests: A Systematic Review and Meta-analysis

Journal of Endodontics, 2018
The aim of this systematic review was to investigate and compare the diagnostic accuracy including sensitivity, specificity, adjusted accuracy, adjusted positive predictive value (PPV), and adjusted negative predictive value (NPV) of cold pulp testing (CPT), heat pulp testing (HPT), electric pulp testing (EPT), laser Doppler flowmetry (LDF), and pulse ...

Testing of analgesics by electrical stimulation of the dental pulp in healthy volunteers

Agents and Actions, 1972
A modified method of electrical stimulation of the dental pulp suitable for testing non-narcotic analgesic substances in healthy volunteers is described. This technique makes it possible to demonstrate dose-response relationships with acetylsalicylic acid and to make accurate comparisons of different substances under double-blind conditions.

An investigation of language used by children to describe discomfort during dental pulp‐testing

International Journal of Paediatric Dentistry, 2000
Aim. Studies of the descriptions of pain by children have neglected their linguistic development, therefore estimates of dental pain in children may not be accurate. This study sought (1) to identify words chosen by children to describe dental pain and (2) to establish the effect of linguistic development on that description. Sample.

In situ testing of CO₂ laser on dental pulp function: Effects on microcirculation

Lasers in Surgery and Medicine, 1991
AbstractThe effect of CO2 laser irradiation on pulpal microcirculation was studied in cat canines. The enamel surfaces of 4 teeth were exposed with energy densities of 304‐1440J/cm2, using either a handpiece or a microslad, with a focal spot of 0.21mm and 0.33mm respectively.

Dental pulp neurophysiology: part 2. Current diagnostic tests to assess pulp vitality.

Journal (Canadian Dental Association), 2009
In this second part of our 2-part review, we discuss recent research about pulp tests that determine the vitality of the tooth and clinically accepted pulp testers. A pain response to hot, cold or an electric pulp tester indicates the vitality of only a tooth's pulpal sensory supply; the response does not give any idea about the state of the pulp ...
