ABSTRACT
Eighty healthy children, between the ages of 2 and 7 years, undergoing dental procedures were monitored with a pulse oximeter for changes in arterial oxygen saturation. The children were randomly allocated into 4 groups in this double-blind study. Three groups received rectal midazolam, and the other group a placebo (saline) as premedication 30 min prior to induction of anesthesia. Group A children received midazolam 0.25 mg/kg, Group B 0.35 mg/kg and Group C 0.45 mg/kg. The results from this trial show no statistical significant difference between the treatment groups as to the effect on either systolic or diastolic blood pressure, respiration, or pulse rates at either pre- or post-sedation levels. However, the oxygen saturation levels for groups B and C differed significantly from those of the placebo groups 30 minutes after premedication (P = 0.0259).

Panoramic dental radiography does not replace conventional techniques for viewing the maxillary sinuses but is a useful adjunct. Unsuspected antral diseases, from innocuous mucosal cysts to insidious squamous carcinoma, may be detected during routine use of this procedure.

Standardized panoramic radiographs were used to determine and compare the prevalences of focal osteosclerosis (including condensing osteitis) and apical periodontal pathoses in a sequential presenting sample of 600 European and 600 Cape Coloured dental outpatients. Most cases of focal osteosclerosis were found in edentulous zones or associated with carious or inadequately restored teeth; however, some were subjacent to apparently sound teeth. Focal osteosclerosis of definite dental origin was just as common in participants aged 25 years and older as in younger individuals. While focal osteosclerosis occurred predominantly in the mandible, apical periodontal pathoses were distributed more evenly between both jaws.
