Background: The aim of the present study was to determine
radiographically the prevalence of developmental abnormalities
of size and form of teeth in patients attending the Dental Faculty
of Near East University of Cyprus and to evaluate the relationship
between gender differences and these anomalies. There are no
previously reported dental records and epidemiologic data available
for this population.
Methods: A retrospective study based on the panoramic radiographs
of 4672 patients aged 16 to 82 attended from January 2007 to
February 2010 was performed in this population. Radiographs were
studied in detail for the presence of possible dental anomalies with 9
examiners. International classification for diseases (ICD) codes was
used for the selection and coding of dental anomalies. Differences
in incidence rates of each dental anomaly by gender and age were
analyzed by using the Pearson chi-square test (P≤0.05).
Results: The more common anomalies were microdontia (% 18,7),
taurodontism (% 17,1), and dens invaginatus (% 12,5). Macrodontia,
were detected in a few radiographs (% 3,5). When the dental
developmental anomalies where examined according to gender with
the Pearson Chi-square test (p≤0.05); it was found that there was no
statistically significant differences between female and male patients
regarding abnormalities of size and form.
Conclusions: Although larger samples are required to effectively
determine the complete description of abnormalities of size and form
of teeth, no dental anomalies were found to occur more commonly
in this ethnic group, compared with previously published data, which
may be considered to be specific to this population according to this
preliminary study.
