The Authors evaluate the most common techniques to close the bite in patients with no overjet, then they suggest a method (anterior cross-bite elastics) that can obviate some of the disadvantages experienced using those techniques.
When mixed dentition therapy is indicated, the Authors suggest the banding of second deciduous molars to avoid the risk of demineralization of first permanent molars. The method suggested is supported by few clinical cases, shown in the figures, where heavy forces are exerted against the second deciduous molar.

To compare the short term effects of a short (Buserelin, 1800 micrograms/day as nasal spray) and a long acting (Triptorelin Depot, 3.75 mg/every 4 weeks i.m.) LHRH agonist, LH and FSH (LHRH test and 2 hours spontaneous rhythm during the morning and during the evening), estradiol and pelvic ultrasonography were evaluated in 12 children (1 boy, mean age 8.24 +/- 1.39 years, mean bone age 9.39 +/- 1.76 years) with early puberty before and after 1 and 2 months of treatment. Informed consent was obtained in all the cases. 6 patients started with Buserelin and 6 with Triptorelin. The therapeutic regimen was crossed over after 2 months of treatment and 2 more months of treatment withdrawal. The results indicate that while in both groups FSH values decreased significantly already from the last month of treatment, patients treated with Triptorelin showed a later LH decrease (significant only after 2 months of treatment). A decrease of pelvic structures volume was however evident only in patients treated with Triptorelin. After 2 months of treatment estradiol levels lowered (but not significantly) in both group. In conclusion despite a later LH decrement, patients treated with the long acting analogue showed however a more evident reduction of pelvic organs volume.
