Author(s): Juman Mohammed Taqi Al-Talqani* and Aseel Haidar MJ Al-Haidar


Objective: To assess the relationship between the enamel defects and the intelligence quotient among a group of children.

Subjects and Methods: A cross sectional study was carried out in Al-Najaf city, Iraq by which a total of (1122) primary school student aged from 8-10 years old were included. All the students were examined for the presence of the enamel defects in the permanent teeth. Their intelligence quotient was determined using Raven’s colored progressive matrices. Statistical analysis was done using SPSS version 21.

Results: The results of the current study showed that the prevalence of the developmental enamel defects among the total sample (22.37%) was more prevalent among the intellectually impaired subjects (24.64%). However, the results were statistically not significant.

Conclusion: This study concluded that a relationship was found between the enamel defects and the level of the intelligent quotient, by which it was highly prevalent among the intellectually impaired children.
