A surface assessment was performed at 10 kV (Zeiss Supra 50 VP, Zeiss, Oberkochen, Germany). Photos were taken at 1000x and 10,000x magnification. Images were taken from a standardized area (300 μm to “right” and “above” from the discs’ central point) Assessment of dentin tubules obturation was performed using the Olley score with values from one to five indicating the degree of occlusion (1 – occluded, 2 – partially unoccluded, 3 – equally occluded/unoccluded, 4 – partially occluded, 5 – unoccluded) [34 (link)].
Supra 50vp
The Supra 50VP is a field emission scanning electron microscope (FE-SEM) developed by Zeiss. It provides high-resolution imaging and analysis capabilities for a wide range of applications. The Supra 50VP utilizes a Schottky field emission electron gun to generate a high-brightness electron beam, enabling detailed observation and characterization of samples at the nanoscale level.

Characterizing Dentin Tubule Obturation via EDX Analysis
On this behalf, the samples were newly embedded in resin and vapor-coated with coal powder which allowed for a better discrimination by backscatter analysis. Photos of the intersections were made at 10 kV (Zeiss Supra 50 VP) and at a magnification of 10.000x. Element analysis was performed from the tubular plugs and – as a control - from intertubule dentin areas.
Imaging was performed by a single operator (BS) who was unaware of the pre-treatment of the specimen. Likewise, the person analyzing the respective images (PS) was blinded to the group allocation.
Characterization of Microcapsule Morphology and Composition
Thermogravimetric analysis (TGA, TA Instruments TAQ50, TA Instruments, New Castle, DE, USA) was used to determine MMI-2/PA content within microcapsules [10 (link)]. The amount of encapsulated solution is taken as the mass loss during the TGA run. Capsule specimens were heated at a rate of 5 °C min−1 to 100 °C and held for 30 min to stimulate water loss. This was followed by heating to 180 °C for 30 min and 200 °C for 60 min, which bracketed the boiling point of PA (b.p. 196 °C).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
