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

Tooth size discrepancy of the permanent dentition in class II div. 1 malocclusion with crowding or spacing

A proper relationship of the total mesiodistal width of the maxillary dentition to that of the mandibular dentition will favor an optimal post treatment occlusion, the purpose of this study is to compare the mesiodistal crown dimension and tooth size discrepancy in subject with class II div.1 malocclusion with spacing or crowding in the upper and lower arches. Sixty pairs of dental casts were obtained [30 crowding, 30 spacing] were measured and analyzed, the results indicates males generally have greater mesiodistal crown dimension than females in both crowding and spacing groups, and there was a significant difference between both groups with greater mesiodistal width for the crowding group, and non significance difference regarding tooth size analysis [Bolton ratio]
