Multiple supernumerary teeth (MST) in non-syndromic patients are linked to specific positions, eruption issues, and complications. MST also increases the risk of adjacent tooth displacement and requires combined orthodontic and extraction treatments.
Area of Science:
- Dental Anomalies
- Oral Surgery
- Developmental Biology
Background:
- Supernumerary teeth (ST) are common developmental anomalies.
- Factors influencing single supernumerary teeth (SST) versus multiple supernumerary teeth (MST) require further investigation.
Purpose of the Study:
- Identify factors associated with single supernumerary teeth (SST) and multiple supernumerary teeth (MST).
- Analyze these factors in a non-syndromic Brazilian population.
Main Methods:
- Cross-sectional study of 305 non-syndromic patients with ST over 10 years.
- Collected data on patient demographics, ST morphology, location, position, eruption, complications, and treatment.
- Utilized Mann-Whitney, chi-squared, and logistic regression analyses.
Main Results:
- 460 ST identified in 305 patients; 62.2% had SST, 37.8% had MST.
- MST showed strong associations with specific position, eruption, orientation, clinical complications, morphology, and treatment characteristics (p < 0.001).
- Male predominance (68.2%) and mean age of 9.3 years observed.
Conclusions:
- Tuberculate and supplemental ST, palatal positioning, and eruption status are significantly linked to MST.
- MST increases the risk of adjacent tooth displacement and necessitates combined orthodontic treatment and extraction.

Teeth
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...

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
