Summary
Root structure showed no glucose leakage, but filled root canals did, regardless of filling material. This indicates that root canal fillings, not the root structure itself, are susceptible to leakage.
Area of Science:
- Endodontics
- Dental Materials Science
- Biomaterials
Background:
- Root canal sealants are crucial for preventing microleakage.
- Assessing leakage through root structure versus coronal root fillings is essential for endodontic success.
Purpose of the Study:
- To evaluate glucose penetration and fluid transport through coronal root structure.
- To compare this with leakage along coronal root fillings using different materials.
Main Methods:
- 50 single-rooted teeth were divided into root structure, Resilon + Epiphany, and gutta-percha + AH26 groups.
- Glucose penetration was assessed over 4 weeks; fluid transport was measured subsequently.
- Statistical analysis included Kruskal-Wallis and Mann-Whitney tests.
Main Results:
- No glucose penetration or fluid transport was observed through the root structure.
- Significant glucose leakage occurred through filled root canals for both Resilon and gutta-percha groups.
- No significant difference in leakage was found between Resilon + Epiphany and gutta-percha + AH26 fillings.
Conclusions:
- The coronal root structure is impermeable to glucose and fluids under tested conditions.
- Filled root canals are prone to leakage, irrespective of the filling material used (Resilon or gutta-percha).
- Further research may focus on improving the sealing ability of root canal filling materials.

02:34Water and Mineral Acquisition
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.
01:23Transcellular Transport of Solutes
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is primarily seen in epithelial and endothelial cells aided by membrane transport proteins such as channels and transporters. The tight junctions between these cells confine the membrane proteins to the two sides of the cell. The epithelial cells have distinct apical and basolateral domains. In contrast, the endothelial cells show the luminal...
01:46The Apoplast and Symplast
Plant growth depends on its ability to take up water and dissolved minerals from the soil. The root system of every plant is equipped with the necessary tissues to facilitate the entry of water and solutes. The plant tissues involved in the transport of water and minerals have two major compartments - the apoplast and the symplast. The apoplast includes everything outside the plasma membrane of living cells and consists of cell walls, extracellular spaces, xylem, phloem, and tracheids. The...
02:03Xylem and Transpiration-driven Transport of Resources
The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that transport xylem sap are dead upon maturity, and the movement of xylem sap is a passive process.
02:12Short-distance Transport of Resources
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.
01:26Glucose Absorption Into the Small Intestine
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and 'exit' via the...
