Dental Crown Dimensions and Third Molar Agenesis in German Orthodontic Patients

A German study of 314 orthodontic patients (156 males, 158 females) investigates the association between third molar agenesis and mesiodistal crown dimensions. The dataset includes 89 patients with third molar agenesis and 225 controls, with measurements taken for each fully erupted permanent tooth. The research was authored by Gloria Guht and last updated in May 2026.

Use Cases

• Compare mesiodistal crown widths between patients with and without third molar agenesis based on the study's group comparisons.
• Analyze gender-specific differences in tooth dimensions based on the significant findings reported for males and females.
• Investigate correlations between the number of missing third molars and crown size reductions based on the reported negative moderate correlations.
• Study the distribution of third molar agenesis across genders based on the chi-square test and odds ratio analysis.

Strengths

• Includes 314 patient records with gender balance (156 males, 158 females).
• Contains a defined control group of 225 patients with a full complement of 32 teeth.
• Reports specific statistical results, including p-values, odds ratios, and correlation coefficients.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to a single-country (Germany) sample.
