Relating to or located at the apex, tip, or pointed end of something, especially the tip of a tooth, root, or leaf.
From Latin 'apex' (tip) with the '-al' suffix meaning 'of or pertaining to.' The term is widely used in anatomy, botany, and dentistry.
Dentists obsess over apical seals in root canals because if bacteria can sneak past the very tip (apex) of a tooth root, they can cause massive infections—making that tiny point of precision absolutely critical to your health.
