Perio Terminology Glossary
A plain-English glossary of recurring periodontology terms that helps early learners read articles, charts, and evaluations with less friction.
Use the glossary to remove friction, not replace deeper study
Glossaries are most useful when they help you keep moving through a topic without getting stuck on every unfamiliar word. The goal is not to memorize every definition in isolation, but to make the larger concepts easier to absorb.
Core terms that appear repeatedly in perio study
A small number of recurring terms do a lot of the work in early periodontology learning. If you understand these well, articles about charting, disease progression, recession, and evaluation become far easier to follow.
- Gingiva: the soft tissue commonly referred to as the gums
- Periodontal ligament: the connective tissue structure that helps anchor the tooth
- Cementum: the root surface layer that supports attachment
- Alveolar bone: the bone that surrounds and supports the teeth
- Probing depth: the measured depth of the sulcus or pocket at a site
- Recession: apical movement of the gingival margin that exposes more root surface
- Clinical attachment loss: a measure that helps describe lost periodontal support over time
- Bleeding on probing: a finding that can point toward inflammatory activity
Keep linking vocabulary back to charting and evaluation
Terminology becomes easier to remember when you keep seeing where it belongs. Ask yourself whether a term describes tissue anatomy, an inflammatory finding, a measurement, or a treatment-related concept. That makes the glossary part of your reasoning process rather than a detached list.
Educational note
This glossary is meant to support learning and revision. Definitions are intentionally concise so they stay useful during study sessions.
