There was a significantly higher risk of compromised or impaired endocervical margin in the conization specimen resulting from LLETZ-cone compared to SWETZ (RR = 1.72, 95% CI: 1.14-2.6), with an ARR of 26.4% (95% CI: 8.1-44.8) for patients who underwent SWETZ.
In addition, the changes in the internal micro-structure of the specimens resulted from variations in the stress condition, were found to affect the ultrasonic velocity measurements.
The significantly lower tensile strength of dentin restored with PanaviaF, Variolink II, and Single-Bond + RelyX specimens resulted from adhesive failure on the dentin side of the interface.
On the other hand, a study by Pazos et al. [ 37] on CP-Ti showed that the fatigue behavior of a blasted surface and of an as-machined surface is similar even though fatigue crack nucleation, on grit blasted specimens, resulted from stress raisers notches which were created by the alumina particles.
While the analysis of cryopreservation effects in small specimens frequently benefits from spatial uniformity in temperature and in ICA concentration, higher complexity is introduced to the analysis of large-size specimens, resulting from significant temperature and concentration gradients.
The second-largest marine collection in New Zealand is the NIWA Invertebrate Collection, Wellington, which holds specimens resulting from more than half a century of collecting in the New Zealand region, the southwestern Pacific, and the Ross Sea.
Bleached specimens, resulting from symbiosis disruption, and maintained bleached over several years (at 17°C in dark conditions) were also sampled.
This study showed a lower proportion of compromised or damaged endocervical surgical margin in specimens resulting from SWETZ in relation to LLETZ-cone.
Most biological specimens resulting from such inventories are stored in private collections, museums, or herbaria that are not easily accessible to the general public.
To calculate the sample size, the study considered data from the preliminary study, mentioned above, which showed compromised margin in 4% of the specimens resulting from SWETZ, and in 20% from LLETZ-cone [ 14].
