EndodonticsA permanent tooth with apical one-third root fracture would most likely remain vital and functional. Apical third fractures have favorable prognosis because: 1) Good blood supply is maintained to the coronal fragment through the periodontal ligament, 2) The fracture is away from the oral environment, reducing contamination risk, 3) Pulp often remains vital due to minimal disruption of apical blood supply, 4) Healing usually occurs with fibrous union between fragments, 5) Function is typically maintained. Root resorption and ankylosis are less common with apical third fractures compared to cervical fractures.

Endodontics
1) The upper first premolar usually has two canals: This statement is true. While the presence of two canals in the upper first premolar is not guaranteed, it is quite common to find two canals in this tooth.
2) Root canal instruments are best sterilized by a chemical method: This statement is false. The best method for sterilizing root canal instruments is heat sterilization using an autoclave. Chemical methods can be used for surface disinfection but are not adequate for sterilization.
3) All root canals must be enlarged to at least a size 25 file: This statement is true. Enlarging the root canals to a size 25 or larger is a part of the cleaning and shaping process in root canal therapy to ensure thorough debridement and preparation for filling.

Physiology
The glomerular filtration barrier is composed of the glomerular capillary endothelium, the basement membrane, and the podocytes (Bowman's visceral epithelium). These three layers work together to filter blood and form the glomerular filtrate, which then enters the renal tubules.
