    Summary: This clinical guide, featuring a wealth of high-quality photographs, will help pediatric dentists, pediatric dentistry residents and general dental practitioners treating children, acquire a clear understanding of contemporary treatment protocols for primary and young permanent teeth while serving as a guide to integrate these procedures into their private or institutional practice. The background to the book is the emergence in recent years of important paradigm shifts in treatment concepts. It is now recognized that clinicians must distinguish between “caries management” and “carious lesion management” when treating children. Moreover, regenerative endodontic procedures have changed the way in which the immature permanent tooth is treated. The authors present the full range of current treatment techniques step-by-step, with all the necessary detailed photographic documentation and succinct supporting text. It will be an asset for dentists worldwide. -- Provided by publisher.

    The effect of frontal hypothalamic deafferentation on the release of LH and FSH was studied in ovariectomized rats. Frontal cuts were placed just in front of the arcuate nucleus, at the posterior border of the optic chiasma (RCS), at the level of the anterior commissure (POS) and in front of the optic chiasma (PCS). Animals with RCS and POS cuts showed vaginal smears with persistent cornification; the other groups had irregular cycles. The concentrations of LH and FSH in the serum increased after ovariectomy in deafferentated animals, but after 4 weeks the levels were lower than in the animals without hypothalamic lesions except for the PCS group. The more caudally that the cuts were located, the lower were the concentrations of hormones in the serum. The injection of repeated doses of oestradiol benzoate resulted in a decrease in serum gonadotrophin of both rats without hypothalamic lesions and RCS rats. Although a greater decrease was observed in the lesioned than in the intact rats, it is believed that such an effect does not indicate an increased sensitivity of deafferentated animals to this steroid. The stimulatory effect of progesterone on LH and FSH release was studied in ovariectomized rats primed with oestradiol benzoate. The responses were unchanged in PCS animals but failed to occur in POS and RCS rats. Measurement of the level of gonadotrophin-releasing hormone in frontal hypothalamic slices from RCS animals showed a decreased level behind the cut and an increased one in front of it, suggesting that perikarya located in front of the section were sending their axons to the mediobasal hypothalamus. It is believed that the blockade of the stimulatory effect on gonadotrophins by frontal hypothalamic deafferentation is due to the transection of these axons. Cuts placed immediately in front of the arcuate nucleus, however, permitted progesterone-induced gonadotrophin release because of incoming neurones containing gonadotrophin-releasing hormone, which end in structures immediately rostral to the cut. The results indicate that effects of both inhibitory and stimulatory ovarian steroid feedback are impaired by frontal hypothalamic deafferentation.
