Assessment of current adhesives in class I cavity: Nondestructive imaging using optical coherence tomography and microtensile bond strength

Effects of different etching modes on the nanoleakage of universal adhesives: A systematic review and meta‐analysis

“…Scotchbond Universal was the most commonly assessed (10 studies) . Seven studies evaluated All‐Bond Universal, and five tested G‐Bond Plus . Table describes all of the evaluated universal adhesives, their pH, composition, and frequency of assessment.…”

“…Table demonstrates that eight studies presented nanoleakage as a percentage of metallic silver particle deposition or free spaces at the adhesive‐tooth interface, and two studies, as presented in Table , used a classification system devised by Saboia et al Three studies described nanoleakage in a nonquantitative manner (Table ) …”

“…Generally, researchers have used field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), or scanning electron microscopy (SEM) to assess nanoleakage. One study used confocal laser scanning microscopy (CLSM) …”

“…All included studies in the systematic review scored between a medium and low risk of bias (Table ). Of the 13 studies included, 9 demonstrated a low risk of bias,,, 4 of them had a medium risk of bias, and none of them had a high risk of bias according to the parameters considered in the analysis. The studies scored particularly poorly in terms of sample size calculations and blinding of the examiner.…”

Evaluation of Ultrasonic Bonding Strength with Optoacoustic Methods

“…However, there are few studies that relate the optical measurement to evaluation of the bonding strength. The bonded area detected by the optical coherence tomography [24] had a correlation with the bonding strength. Furthermore, nondestructive evaluations are of technical interest, as well as fundamental interest, in the measurement of interfacial strength between dissimilar materials such as metal/polymer dissimilar joints [25] and fiber reinforced composites [26][27][28].…”
