OBJECTIVES To evaluate the microtensile bond strength of total-etch or self-etch adhesives to caries-affected versus normal dentine, and to correlate these bond strengths with DIAGNOdent laser fluorescence and Knoop microhardness (KH) measurements of the substrates. METHODS Extracted carious human molars were ground to expose flat surfaces where the caries lesion was surrounded by normal dent...

An in vivo study was conducted to verify the ability of laser fluorescence (LF) to assess the activity status of occlusal caries in primary teeth, using different air-drying times. Occlusal sites (707) were examined using LF (DIAGNOdent) after air-drying for 3 s and 15 s, and the difference between readings (DIF15 s-3 s) was calculated. For concurrent validation of LF, visual criteria-Nyvad (NY...

The aim was to appraise the evidence on performance of various means for detection incipient caries in vivo. Five databases published and unpublished research were searched studies from January 2000 October 2019. Search terms included “early caries” “caries detection.” Inclusion criteria involved diagnostic test accuracy early permanent primary teeth. A risk-of-bias assessment performed using Q...

Objective The aim of this study was to evaluate the ability of PTR-LUM (The Canary System, CS), laser fluorescence (DIAGNOdent, DD), LED fluorescence (Spectra), and visual inspection (ICDAS II) to detect natural decay around bonded amalgam restorations in vitro. Methods Seventeen extracted human molars and premolars, consisting of visually healthy (n=5) and natural cavitated (n=12) teeth were...

The detection of dental decay has conventionally been dependent upon direct visual assessment of the dried tooth surface under good illumination, tactile assessment of open dental caries using a probe to help clean debris within fissures, clinical experience and the use of dental radiography. Studies have shown considerable variation berween clinicians in the detection of dental caries. Recent ...

BACKGROUND AND OBJECTIVES Few studies have been published that evaluate the usefulness of different caries- diagnostic modalities in general dental practice. The goal of this study was to compare the results of screening for coronal dental caries in a general dental practice using clinical observations, radiographs, laser fluorescence (DIAGNOdent™) (LF), and optical coherence tomography (OCT). ...

Modern knowledge about the essence of the caries process – which takes place in stages and within continuous reversible processes – brought about the emergence of a new conception concerning the its diagnostics [5]. The possibility for nonoperative preventive treatment requires the application of new higher criteria concerning the methods aimed at the verifiable ascertaining of the earliest cha...
