AI Article Synopsis
- The study aimed to analyze the prevalence of taurodontism and learning disabilities among Klinefelter syndrome patients.
- Analysis included questionnaires and dental radiographs, finding taurodontism in 75% and learning disabilities in 83% of participants, which are significantly higher rates than in the general population.
- The findings suggest that if a male patient has taurodontism and a learning disability, there's an 84% likelihood he may have Klinefelter syndrome, highlighting the crucial role dentists play in identifying genetic disorders.
Article Abstract
Purpose: The purpose of this descriptive clinical study was to determine the prevalence rates of taurodontism and learning disabilities in a sample of patients with Klinefelter syndrome.
Methods: Questionnaires and dental radiographs of Klinefelter syndrome patients were obtained and analyzed using previously published methods. Prevalence rates were determined for taurodontism and learning disabilities in the sample population and compared to the general population. Statistical analyses included a Fisher's exact 2-sided test to compare the prevalence rates to that found in the general population and subsequent determination of the positive predictive value.
Results: Taurodontism was found in 75% of the 24 participants. Eighty-three percent of the participants reported having a learning disability. These rates are significantly higher than the general population, as reported in the literature.
Conclusions: The positive predictive value for Klinefelter syndrome, given a male patient with taurodontism and a learning disability, is 84%. In this case, the dentist should recommend karyotyping to the patient, parent, or physician. This demonstrates how important it is for dentists to understand and assist physicians in the diagnosis of genetic disorders.

Objectives: Artificial intelligence (AI) techniques like convolutional neural network (CNN) are a promising breakthrough that can help clinicians analyze medical imaging, diagnose taurodontism, and make therapeutic decisions. The purpose of the study is to develop and evaluate the function of CNN-based AI model to diagnose teeth with taurodontism in panoramic radiography.
Methods: 434 anonymized, mixed-sized panoramic radiography images over the age of 13 years were used to develop automatic taurodont tooth segmentation models using a Pytorch implemented U-Net model.

Dental findings of a child with Wolf-Hirschhorn syndrome.

Department of Child Dental Health, Bristol Dental Hospital, Lower Maudlin Street, Bristol, BS1 2LY, UK.
The case presented is that of a 5-year-old female with Wolf-Hirschhorn syndrome. Dental findings were severe hypodontia, late dental development, taurodontism of the primary molars, microdontia, and spacing. Hypodontia has previously been reported and therefore this case adds to the evidence that hypodontia may be a common feature of this syndrome.
