Boon of MTA Apexification in Young Permanent Posterior Teeth

open access: yesCase Reports in Dentistry, 2014
Single visit apexification using mineral trioxide aggregate (MTA) is a new boon in effective management of nonvital tooth with an open apex which has steadily gained popularity with clinicians; also it shortens the treatment period and improves patient ...

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

open access: yes, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Effect of nonvital tooth bleaching on resin/enamel shear bond strength.

open access: yesThe journal of adhesive dentistry, 2003
This study evaluated the effect of nonvital tooth bleaching on shear bond strength (SBS) of the composite resin/bovine enamel interface at different periods of time after bleaching.Three hundred twenty teeth were randomly divided into four groups according to bleaching agent: SPH: sodium perborate and 30% hydrogen peroxide; SPW: sodium perborate and ...

Six-month follow-up of the effect of nonvital bleaching on IL-1b and RANK-L: A randomized clinical trial

open access: yes, 2019
Objectives: It has been reported that bleaching generates an increase in the activity of osteoclasts in vitro. We quantified the RANK-L and IL-1b biomarkers in a double-blind, randomized clinical trial evaluating the in vivo effect of hydrogen peroxide ...

Reduction of gear pair transmission error with tooth profile modification [PDF]

open access: yes, 2008
The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...
