This meta-analysis and systematic review aimed to assess the efficacy of gingival displacement with the aid of conventional cordless and cords techniques and evaluate the reliability of the estimation methods.
In gingival displacement, the cord
approach led to greater displacement in comparison with the cordless approach.
Assessing sulcular width with the aid of digital microscope images procured
from sectioned gypsum casts appears to be an adequate and versatile
experimental approach for estimating displacement.
This
meta-analysis and systematic review aimed to assess the efficacy of gingival
displacement with the aid of conventional cordless and cords techniques and
evaluate the reliability of the estimation methods.
The
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)
guidelines were followed and detected studies that were then submitted to the
Cochrane risk-of-bias assessment. Utilizing the Review Manager Software, an
evaluation of the gingival displacement was done.
Overall, 9 studies were chosen. The commonly noted risks of bias were: (i) blinding of outcome evaluation, (ii) absence of sample size calculation, and (iii) random sequence generation, and. Most studies demonstrated procuring a width of more than 0.2 mm. Expasyl paste was reported to be the most effective cordless material.
For measuring displacement, assessing the
sulcular width using a digital microscope image procured from a sectioned
gypsum cast is an adequate and versatile experimental approach while evaluating
sulcular width directly on the impression material is a limited methodology.
In
comparison with the cordless approach, the cord approach leads to more
displacement in gingival displacement.
