Periodontal Phenotype
The clinically observable morphological characteristics of the periodontium, encompassing gingival tissue thickness, keratinised tissue width, and alveolar bone thickness.
Full Definition
Periodontal phenotype (formerly termed 'biotype') is the combined assessment of gingival tissue thickness, width of keratinised gingiva, and underlying bone architecture. The 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases formally replaced the term 'gingival biotype' with 'periodontal phenotype' to reflect the broader morphological concept. In research manuscripts, editors must apply this updated terminology and flag use of the outdated 'biotype'. Periodontal phenotype influences treatment planning, surgical outcomes, and implant site assessment, making accurate terminology essential in clinical studies.
Usage
Usage note: 'Gingival biotype' is now considered outdated; editors should replace it with 'periodontal phenotype' in manuscripts targeting contemporary periodontal journals.
In Context
- "Participants were stratified by periodontal phenotype prior to randomisation to account for differences in tissue architecture." — Implant soft tissue augmentation RCT
- "The term 'biotype' should be replaced throughout the manuscript with 'periodontal phenotype' in accordance with the 2017 World Workshop classification." — Peer review copy-editing note
