Background : Although they are not life threatening, dental caries and periodontal disease are the most predominant and widely spread oral diseases throughout the world.

Another most common dental problem seen in children is dental trauma.

The aims of the study included the investigation of the prevalence and severity of dental caries, gingivitis and dental plaque in relation to gender, furthermore, the prevalence and severity of the traumatized anterior teeth were assessed.

Materials and Methods : This oral health survey was conducted among primary school children aged 9 years old in AlDiwaniyah city in Iraq.

The total sample composed of 600 child (320 males and 280 females) selected randomly from different school in Al-Diwaniyah city.

Diagnosis of dental caries was according to the criteria described by WHO (1987).

Plaque index of Silness and Loe (1964) was used for plaque assessment, gingival index of Loe and Silness (1963) was followed for recording gingival health condition.

Diagnosis and recording of traumatic dental injuries was according to Garcia-Godoy's classification (1981).

Results : Results showed that the prevalence of dental caries was 85% for 9 year-old school children.

Regarding primary and permanent dentition, dental caries was higher among females compared to males with statistically significant difference (P<0.05) for primary dentition, on the other hand, males showed higher values of filled surfaces compared to females with statistically significant difference (P<0.05) for primary dentition and highly significant difference (P<0.01) for permanent dentition.

Finding of this study revealed that 100% of the children had gingival inflammation.

Furthermore, the values of plaque and gingival indices were higher among males compared to females with statistically highly significant differences (P<0.01).

The prevalence of children with traumatized anterior teeth was 10.5% of the total sample.

Males were more affected than females, the difference was statistically significant (P<0.05).

Simple enamel fracture was the most common type of injury among traumatized teeth among children.

The maxillary central incisors were the most commonly injured teeth.
