The main reason ameloglyphics (enamel rod end patterns) are not recommended in forensic odontology is due to the inherent biological variability of enamel structure. The course and arrangement of enamel rods change at different levels of the enamel, making the patterns inconsistent and unreliable for unique individual identification.

Oral MedicineOral PrEP with regimens containing Tenofovir disoproxil fumarate (TDF) requires confirmation of adequate renal function, specifically a creatinine clearance of at least 60 mL/min, because TDF can affect kidney function in some individuals. While an HIV test is essential to confirm the person is negative for HIV before starting PrEP, the specific renal function check relates to the drug's safety profile.
