cementum
This term refers specifically to the mineralized tissue that anchors the tooth root to the periodontal ligament. It is a highly technical anatomical term used almost exclusively in dentistry and histology, carrying a neutral, clinical connotation.
As a mass noun representing a biological substance, it is treated as uncountable. It does not have a plural form in standard medical usage; instead, practitioners refer to the substance itself or use phrases like layers of cementum to describe quantity or thickness.
