oligodontia
Very Low FrequencySpecialised Technical / Medical
Definition
Meaning
A dental condition characterized by the congenital absence of six or more permanent teeth.
Often part of a broader genetic syndrome or developmental disorder affecting ectodermal structures, it can involve both primary and permanent dentition and has implications for oral function and facial development.
Linguistics
Semantic Notes
The term is specific to dentistry and medical genetics. 'Hypodontia' refers to the absence of fewer than six teeth and is a more common term; 'oligodontia' indicates a more severe form. 'Anodontia' is the total absence of teeth.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning, spelling, or usage. The condition is defined identically in both dental communities.
Connotations
Purely clinical, with no regional connotative differences.
Frequency
Extremely rare in general discourse in both varieties. Used exclusively in specialist dental, orthodontic, and genetic literature and practice.

Examples
By Part of Speech
adjective
British English
- The oligodontia case was complex.
- An oligodontia phenotype was identified.
American English
- The oligodontia patient needed implants.
- An oligodontia condition can be syndromic.
Examples
By CEFR Level
- Oligodontia is a rare condition where many teeth are missing from birth.
- Children with oligodontia may need special dental care.
- The genetic study aimed to identify novel mutations responsible for familial, nonsyndromic oligodontia.
- Prosthetic rehabilitation for patients with oligodontia often involves a combination of implants and fixed bridges.
Learning
Memory Aids
Mnemonic
Think: OLIGO (meaning 'few' in Greek, like 'oligarchy' is rule by the few) + DONTIA (relating to teeth, like 'orthodontist'). So, 'few teeth'.
Conceptual Metaphor
DEFICIENCY AS ABSENCE (framing a developmental condition as a lack or shortage of a standard component).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct cognate 'олигодонтия' exists and is used identically in Russian medical terminology, so no trap.
Common Mistakes
- Misspelling as 'oligodentia' (incorrect root). Confusing it with the more general 'hypodontia' or the total absence 'anodontia'.

FAQ
Frequently Asked Questions
No, it is completely different. Oligodontia is the congenital (from birth) absence of teeth, not decay in existing teeth.
Yes, treatment is possible and focuses on functional and aesthetic rehabilitation, often using dental implants, bridges, or dentures, ideally as part of a long-term treatment plan from adolescence.
No, it is a rare condition, much rarer than hypodontia (absence of 1-5 teeth).
It can affect both dentitions, but it is primarily defined and diagnosed based on the absence of permanent (adult) teeth.
