Is there a genetic difference in dental trauma of monozygotic and dizygotic twin children?

AUTHOR(S): Esra Oz and Zuhal Kırzıoglu
ABSTRACT:Aims: It was aimed to investigate the prevalence of dental injuries in twins, and to determine whether there was any differences according to monozygotic and dizygotic twin status.
Material and Methods: Patients were classified as dizygotic and monozygotic twins and the dental trauma history of the patients was questioned. The cause, location of the trauma and the traumatized teeth were recorded. The trauma types were determined by the Andreasen Classification.
Results: The study group consisted of 220 twin patients aged 2–17 years. Of the 110 twin pairs, 86 were dizygotic and 24 were monozygotic twins. Twenty patients in the study group experienced a history of dental trauma (9%). Males were exposed to more dental trauma than females (p<0.05). The dental trauma occurred mostly due to falling (65%) in the street (40%). The number of patients with only one tooth affected was higher. Dizygotic twins experienced more dental injuries than monozygotic twins but the relationship was not statistically significant (p>0.05). 87.5% monozygotic pairs and 82.6% dizygotic pairs were concordant.
Conclusion: Monozygotic and dizygotic twins do not constitute a differentiation in terms of exposure to dental trauma. Environmental factors seem to play a significant role in determining etiological risk factors.
