Revisiting the future of root canal obturation

Endodontology, 2022
The techniques for root canal obturation have undergone several changes in the last 10 years. While warm vertical compaction had been the major method of filling the canal, which included the use of core carriers made of structurally stable gutta-percha,

A comparative evaluation of five obturation techniques in the management of simulated internal resorptive cavities: An ex vivo study

Journal of Pharmacy and Bioallied Sciences, 2019
Background: Root resorption is the loss of dental hard tissues as a result of clastic activities. It might be broadly classified into external or internal resorption by the location of the resorption in relation to the root surface.

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...
