EndodonticsThe untrue statement about gutta-percha is that it is indicated in fine canals. Actually: 1) Gutta-percha IS compatible with post preparation, 2) It is NOT ideal for fine canals - silver points or paste fillers work better in very narrow canals, 3) Major composition includes gutta-percha (20%), zinc oxide (66%), waxes and resins, NOT zinc oxide eugenol, 4) It DOES shrink slightly after obturation due to cooling. Fine, calcified canals are difficult to obturate with gutta-percha cones due to size limitations, making other materials more suitable for such cases.

EndodonticsFormocresol is a commonly used fixative and disinfectant in endodontic treatment. It is known to produce tissue fixation by causing coagulative necrosis. This is the process by which the proteins within the tissue are coagulated or precipitated, leading to the death of cells due to dehydration and denaturation. The necrotic tissue is then replaced by a fibrous connective tissue, which is essential for the healing process in the periapical region following root canal treatment.
