Taurodontism, a condition affecting tooth development, is more common than previously thought in individuals without oro-facial disorders. Dentists should be aware of its prevalence and measurements.

Area of Science:

  • Oral and Maxillofacial Radiology
  • Dental Anatomy
  • Endodontics
  • Orthodontics
  • Restorative Dentistry

Background:

  • Taurodontism was historically viewed as solely indicative of oro-facial disorders.
  • Recent studies reveal a moderate-to-high prevalence of taurodontism in individuals without apparent oro-facial anomalies.
  • This higher-than-expected prevalence has been observed in diverse ethnic groups, including Brazilian, Middle Eastern, and East Asian communities.

Purpose of the Study:

  • To highlight the increased prevalence of taurodontism in seemingly healthy populations.
  • To inform dental specialists about the clinical significance of this finding.
  • To emphasize the importance of radiologist awareness regarding taurodontism measurements.
Keywords:

Main Methods:

  • Analysis of case series reporting taurodontism prevalence.
  • Review of panoramic radiographs from various ethnic communities.
  • Focus on individuals without diagnosed oro-facial disorders.

Main Results:

  • Taurodontism exhibits a moderately high-to-high prevalence in individuals without oro-facial disorders.
  • The phenomenon is documented across Brazilian, Middle Eastern, and East Asian populations.
  • The observed prevalence necessitates a re-evaluation of taurodontism's diagnostic implications.

Conclusions:

  • The higher prevalence of taurodontism in normal individuals is clinically relevant for endodontists, orthodontists, and restorative dentists.
  • Oral and maxillofacial radiologists must be knowledgeable about taurodontism and its measurements.
  • Radiologist awareness aids in providing better guidance to clinical dental colleagues regarding this dental anomaly.
