Summary
Visible third molars are associated with increased periodontal probing depths, especially in second molars. This finding suggests a larger biofilm-gingival interface in individuals with visible third molars.
Area of Science:
- Periodontology
- Oral Health Research
Background:
- Third molars, or wisdom teeth, can impact oral health.
- Assessing the periodontal status of adjacent teeth is crucial.
Purpose of the Study:
- To evaluate the link between visible third molars and the periodontal health of anterior teeth.
- To analyze periodontal probing data from existing studies.
Main Methods:
- Systematic review and meta-analysis of 4 studies.
- Inclusion of periodontal probing data from 6 sites per tooth.
- Forest plot analysis to compare probing depths based on third molar visibility.
Main Results:
- A correlation was found between visible third molars and increased periodontal probing depths.
- This effect was most pronounced in the first and second molars.
- Visible third molars contribute to a larger biofilm-gingival interface.
Conclusions:
- Individuals with visible third molars tend to exhibit greater periodontal probing depths.
- Second molars are particularly affected.
- A larger biofilm-gingival interface is associated with the presence of visible third molars.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
