Area of Science:

  • Dentistry
  • Genetics
  • Oral pathology

Background:

  • Down syndrome is a genetic disorder associated with various health conditions.
  • Dental anomalies, including taurodontism, are frequently observed in individuals with Down syndrome.
  • Understanding the prevalence and characteristics of taurodontism in this population is crucial for dental care.

Purpose of the Study:

  • To diagnose taurodontic teeth in individuals with Down syndrome.
  • To determine the grade of taurodontism, sex distribution, and specific tooth involvement.
  • To analyze the frequency of different taurodontism forms.

Main Methods:

  • Analysis of 43 pantograms from subjects with Down syndrome.
  • Diagnosis and classification of taurodontism based on established criteria.
  • Assessment of sex distribution and individual tooth prevalence.

Main Results:

  • Taurodontic teeth were present in 55.8% of subjects (32.6% females, 23.2% males).
  • Second molars were most commonly affected (53.2%), followed by first molars (40%) and third molars (6.5%).
  • Mesotaurodontism was the most frequent form (72.5%), followed by hypotaurodontism (9.7%) and pyramidal teeth (17.7%). Hypertaurodontism was not observed.

Conclusions:

  • Taurodontism is highly prevalent in individuals with Down syndrome.
  • The prevalence and specific forms of taurodontism vary within this population.
  • Findings highlight the need for routine dental screening for taurodontism in Down syndrome patients.
