A 2008 review of animal research found that low-dose BPA maternal exposure can cause long-term consequences for the neurobehavioral development in mice. [58] A 2008 review of studies concluded that BPA altered long-term potentiation in the hippocampus and even nanomolar (10 −9 mol) dosage could induce significant effects on memory processes. [59]
Tooth discoloration is common following root canal treatment; however, the exact causes for this are not completely understood. [46] Failure to completely clean out the necrotic soft tissue of the pulp system may cause staining, and certain root canal materials (e.g. gutta percha and root canal sealer cements) can also cause staining.

Palaquium gutta. Gutta-percha is a tree of the genus Palaquium in the family Sapotaceae, which is primarily used to create a high-quality latex of the same name. The material is rigid, naturally biologically inert, resilient, electrically nonconductive, and thermoplastic, most commonly sourced from Palaquium gutta; it is a polymer of isoprene which forms a rubber-like elastomer.
Failure of root canal treatment is directly related to the lack of seal on the coronal 1/3 and apical 1/3 portion. A. Coronal 1/3 The problem is with the Obtura backfill that is used in the warm gutta percha technique. Under the surgical microscope, there is an obvious gap between the heated and cooled gutta percha and the dentinal wall.
In general, the safety and effectiveness of alternative medicines have not been scientifically proven [1] and remain largely unknown. [2] Beyond adverse effects from the herb itself, "adulteration, inappropriate formulation , or lack of understanding of plant and drug interactions have led to adverse reactions that are sometimes life ...
After the endodontic procedure has been completed, and the root canal(s) is/are filled with the inert gutta percha root canal filling material, some gutta percha is removed from the canal space. Gutta percha can be removed mechanically (use of Gates Glidden), [9] thermally (use of System B Tip), [10] and chemically (use of chemical solvents ...
The company claims to have helped more than four million people lose weight and it’s tagline is “Go Lose Weight, Go Look Great, Go Love Life.” It all adds up to the “GOLO” diet, created ...
Similar to gutta-percha, there are master cones in all ISO sizes and accessory cones in different sizes and taper available. The major difference between the polycaprolactone-based root canal filling material (Resilon and Real Seal) and gutta-percha is that the PCL-based material is biodegradable, [11] whereas gutta-percha is not. There is a ...
