Research output: Contribution to journalArticlepeer-review


The research objectives were to determine the prevalence of impacted teeth in orthodontic patients in Israel, examining the epidemiological and genetic linkage. Methods: Data was collected from the cohort of patients treated in Tel-Aviv University between 2010–2017. Forty-five patients treated for impacted teeth were randomly selected, compared to 45 control patients, paired by age and sex. Collected data included: week of birth, type of birth, medical history, dental anomalies, treatment referee, chief complaint, treatment modalities and treatment duration. Results: The periodic prevalence of impacted teeth was 11.9%. There was a statistical tendency in the week of birth and type of birth (earlier birth week and more caesarean sections in the study group). Statistical significance was found for systemic disease, chief complaint, referee for treatment and treatment duration. Dental anomalies for the patient or first-degree relatives found odds ratio for the presence of an impacted tooth up to 6 times higher. Conclusions: There is epidemiological data related to impacted teeth, such as preterm births and caesarean sections, with the need for further research.
