Seasonality, incidence, and sex distribution of cleft lip and palate births in Trent Region, 1973-1982.
The birth dates of 930 children born in the Trent Region 1973-1982 with a diagnosis corresponding to cleft palate, or cleft lip with or without cleft palate, was obtained from Hospital Activity Analysis. These data were analyzed to look at the incidence of clefting, sex distribution, and seasonal variation. The results obtained show a significant peak incidence of cleft palate births in August and September, with a low incidence in March to May. Cleft lip, with or without cleft palate, shows a different seasonal trend, with peak occurrence in December and January and a low frequency in May and June. These seasonal trends may act as a pointer to the environmental factors active in the multifactorial etiology of cleft lip and cleft palate.

Localisation of misplaced maxillary canines: orthopantomograph and P.A. skull views compared.
A comparison of the radiographs of 59 subjects who had misplaced maxillary canines has been undertaken. The purpose of this study was to see if the position of the canine as seen on a P.A. skull radiograph is comparable with the position of the canine on an orthopantomogram. The results of the study show that there are similarities in the position of the canines as seen on the two radiographs. Where there is a variation between the two films, there is a tendency for the canine angulation to be increased on the orthopantomogram. The misplaced canine also appears further away from the midline on the orthopantomogram.
