Objective: The odontometric assessment of teeth has been considered as crucial for the identification of individuals due to its correlation with body stature. This investigation aims to collect odontometric data on the anatomical dimensions of both mandibular and maxillary anterior and posterior teeth, and to correlate these variables with stature and gender within the Iraqi subpopulation using cone-beam computed tomography analysis.
Methods: This prospective study involved 826 participants, comprising 370 females (44.8%) and 456 males (55.2%), categorized into two height groups: short and tall, based on average height thresholds. Odontometric data, including total tooth length, root length, crown length, and crown width measurements, were recorded via Cone-beam computed tomography. Additionally, physical stature was measured using standardized anthropometric techniques. Statistical analysis was performed using Student's t-test.
Results: Overall, the findings indicate a positive and statistically significant correlation between all odontometric measurements and stature for both genders, with p-values less than 0.05. Notably, maxillary canines exhibited the strongest correlation with stature, followed by maxillary first molars. In contrast, lower central incisors for males and lower second premolars for females showed the weakest correlation. The correlation for crown width was strongest for maxillary canines and mandibular first molars, while lateral incisors and maxillary second molars presented the weakest correlation. Comparing the dimensions of corresponding right and left side teeth revealed some variations, with a few patients displaying differences exceeding 0.45 mm. At the same time, differences were found to be statistically insignificant for the majority of other teeth, with maximum variations reaching only 0.08 mm between contralateral teeth. Furthermore, significant sexual dimorphism was also observed, with male teeth presenting significantly greater dimensions than female teeth, except in the lower central incisors.
Conclusions: The current clinical study highlights the presence of significant sexual dimorphism and confirms a positive and significant relationship between individual stature and tooth dimensions across both genders.
