Distribution and Prevalence of Various Developmental Dental Anomalies in Iraqi population : A Radiographic Study

Abstract

Aim: To determine the prevalence of dental anomalies in Iraqi population, and
investigate their possible association with gender and teeth.
Materials and methods: Panoramic radiographs of 800 patients out of 350 with
dental anomalies (200 females and 150 males) ,an age range of 18–30 years ( 300
: 18-25 years ; 50: 25-30 years ) were examined for anomalies in teeth number,
shape, size and position.Descriptive statistics was performed using SPSS. The
level of significance was set at 95% confidence level.
Results: Among the 800 radiographs examined, a total of 350 (43.8 %) had
developmental dental anomalies which includes 150 (42.9%) males and 200
(57.1%) females. Around 290 (82.9%) had at least one anomaly, 50 (14.2%) cases
with two anomalies and only 10 (2.9%) exhibited more than two anomalies. Both
males and females were equally affected. Of these 350 anomalies, 300 (85.7%)
occurred in the age group 18–25 years compared to 50 (14.3%) cases in 25–30
years range .
Conclusion: The high prevalence of Developmental Dental Anomalies suggests the
need to increase the understandingof their etiology and aid for better management,
intervention and prevention.
