overbite of Iraqi teenagers [a national survey]

A national survey of the overbite in Iraqui teenagers provides us with a norm of overbite in our nation. More than seven thousand 13 year olds with no history of orthodontic treatment were examined from six governorates [Baghdad the capital, Ninevah, Basrah, Diyala, Anbar and Najaf]. An intra-oral clinical examination was used to assess their overbite. The mean overbite of the sample was 2.557 +/- 0.018mm being significantly higher in males than females. Deep bite [>5mm] was found in 8.7% of the sample being significantly more prevalent among males. Anterior open bite was found in 2.2% of the sample being significantly more prevalent among females

relation between mandibular morphology and lower arch crowding in skeletal class I Iraqi adults

This study is designed to evaluate the morphological feature of the mandible and to establish the effect of three crowded lower arch group [mild, moderate and severe] on the mandibular morphology and dento-facial complex structures for Iraqi young adult sample at 18-25 years of age with skeletal class I. The sample consists of 100 Iraqi adults [50 males and 50 females]. Lateral cephalometric radiographs and lower dental casts of 36 subjects [18 males and 18 females] with mild crowded mandibular dentition and other 33 subjects [18 males and 15 females] with moderate crowded mandibular dentition and other 31 subjects [14 males and 17 females] with severe crowded mandibular dentition were compared. The results showed that all linear measurements were significantly larger in males than in females in all crowded groups. Non-significant differences in all linear measurements were found between mild, moderate and severe crowded groups

overbite of Iraqi teenagers [a national survey]

More than seven thousand 13 year olds with no history of orthodontic treatment were examined from six governorates [Baghdad the capital, Ninevah, Basrah, Diyala, Anbar and Najaf]. An intra-oral clinical examination was used to assess their overbite. The mean overbite of sample was 2.557 +/- 0.018 mm being significantly higher in males than females. Deep bite [>/= 5mm] was found in 8.7% of the sample being significantly more prevalent among males. Anterior open bite was found in 2.2% of the sample being significantly more prevalent among females

Cleft lip and palate [cross sectional study part II]

Cleft lip and palate is defined as a common congenital deformity, although not fatal, unless associated with other serious congenital diseases. This study is done to record the distribution of the cleft types and if there is any association between different risk factors, in the period from January 2002 to March 2003. These are case series survey covering 50 patients with cleft lip and palate attending or refereed to specialized clinic. Detailed forms prepared for those patients were filled. Cleft lip and palate patients represent 56%, cleft palate was 24%, cleft lip 20%, and females were affected more than males. The third birth order child has the highest frequency and the highest percentage of babies was born in October. Cleft lip and palate shows a variation in the distribution and association between different risk factors

national Iraqi survey on anterior crossbite

About seven thousand 13 year olds with no history of orthodontic treatment were selected from six governorates [Baghdad the capital, Ninevah, Basrah, Diyala, Anbar and Najaf]. An intra-oral clinical examination was used to assess the presence of crossbites. Of the sample, 5.5% had anterior crossbite [4.4% had one to three inverted incisors and 1.1% had a mandibular overjet involving all four incisors]. This was non-significantly related to gender and residency
