The Effect of EDTA with and without Ultrasonics on Removal of the Smear Layer

Journal of Endodontics, 2009
This study evaluated in vitro effectiveness of 17% EDTA with and without ultrasonics on smear layer removal. One hundred and five extracted premolars randomly divided into seven groups were instrumented with different final irrigating protocols: group A (Sal3US), saline for 3 minutes with ultrasonics; groups B (Na3) and C (Na3US), 1% sodium ...

ARE THE PERCEPTUAL EFFECTS OF SPECTRAL SMEARING INFLUENCED BY SPEAKER GENDER?

Journal of Basic and Clinical Physiology and Pharmacology, 2004
The purpose of this study was to determine whether the effect of loss of spectral detail on speech perception is influenced by the gender of the speaker. Spectral smearing was carried out by multiplying the speech signal by a series of low-passed white noise samples, causing tonal components in the signal to be replaced by noise. Smearing bandwidths of

Time Interval Effect on Repeat Cervical Smear Results

Acta Cytologica, 1997
Second cervical smears obtained at short time intervals often exhibit a lesser degree of abnormality than the first smear. We studied the effect of time interval between smears on diagnoses in two large, distinctive cohorts.Patients with two or more satisfactory smears with at least one smear or a cervical biopsy showing atypical squamous cells of ...

An empirical correction for the MWR brightness temperature smear effect

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The Microwave Radiometer (MWR), on board of the SAC-D/Aquarius satellite, is a Dicke radiometer, operating at 23.8 and 36.5 GHz that was developed by Argentine Space Agency, CoNAE. Since the first earth surface T B images, there has been an anomalous effect when observing strong contrast radiometric scenes, such as land/water crossings. This effect is

The effect of smear layer removal on marginal contraction gaps

Journal of Oral Rehabilitation, 1994
SummaryThe presence of the smear layer prevents direct contact between dentine and a dentine adhesive. The use of agents to remove the smear layer theoretically should improve the bonding of composite resins to dentine. This study examined the effect of smear layer removal on the effectiveness of a dentine bonding agent in reducing marginal contraction

Effect of the smear layer on a pulp proximity-indicating instrument

Odontology, 2011
The purpose of the study was to determine the effect of removing or modifying the smear layer on the indication provided by the Prepometer pulp proximity-indicating instrument. Third molars were prepared to produce flat surfaces in the coronal dentine, and control Prepometer LED readings were made.

Effect of Ultrasonic Activation of Irrigants on Smear Layer Removal

Journal of Endodontics, 2015
The objective of this study was to evaluate the efficacy of passive ultrasonic irrigation (PUI) with 17% EDTA and 1% NaOCl solutions on smear layer removal.Root canal preparations of 32 human teeth were performed with the ProTaper system. Next, they were longitudinally fractured to permit quantitation of smear layer creation from the cervical, middle ...

Condensate-smearing effect in inelastic scattering on Bose liquids

Physical Review B, 1992
It is argued that the response function of a liquid of interacting particles containing a condensate fraction has a nonvanishing width at the quasielastic peak, unlike the otherwise expected \ensuremath{\delta}-function peak for a noninteracting system.

The Cytobrush effect on Pap smear adequacy.

Family practice research journal, 1991
One hundred twenty-four Papanicolaou smears were studied to compare the yield of endocervical cells obtained with the Cytobrush/Ayre spatula method to that of the cotton-tipped applicator/Ayre spatula method. Forty-nine of the 62 Pap smears (79%) obtained with the combination Cytobrush/Ayre spatula method contained endocervical cells, compared to 22 of

[The effect of smear layer on apical microleakage].

Shanghai kou qiang yi xue = Shanghai journal of stomatology, 2015
To evaluate the effect of smear layer on apical microleakage in extracted root-filled teeth by SEM and glucose penetration model.51 straight single-rooted human teeth were randomly divided into 5 groups, instrumented and irrigated differently by groups.
