Summary

[edit]
Description
English: Diagram showing mesio-impacted mandibular third molar tooth, with associated dental caries and pericoronitis. Captions are (A) Mesio-impacted, partially erupted mandibular third molar; (B) Dental caries and periodontal defects o both the third and second molars, caused by food packing and poor access to oral hygiene; (C) Inflamed operculum covering partially erupted lower third molar, with accumulation of food debris and bacteria underneath; (D) The upper third molar has over-erupted due lack of opposing tooth contact, and may start to traumatically occlude into the operculum over the lower third molar.

This biology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Lower mandibular third molar impaction pericoronitis diagram.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
This biology image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
