  • Laron syndrome was first described by Dr. Laron. Administration of exogenous growth hormone failed to stimulate insulin-like growth factor-I(IGF-I) production which was related to postnatal growth, because these patients lacked receptors in the liver for this hormone. The diagnosis of this syndrome is based on the typical features of GH resistance such as normal or elevated serum GH, low serum IGF-I, and impaired IGF-I response to hGH. Laron syndrome patients showed characteristically severe postnatal growth failure and markedly reduced adult height. This report describes the oral and maxillofacial manifestations of children associated with Laron syndrome. Children with Laron syndrome have several dental and skeletal irregularities. Relatively little is known of the direct effect of Laron syndrome on dental development. Further research should be needed.

  • Dental injuries with crown fracture occur frequently, especially in young patient Reattachment of the crown fragment has been shown to yield good esthetic results in that original tooth anatomy is restored with a material that abrades at a rate indntical to that of the adjacent tooth substance and at the same time permits continual monitoring of pulpal status through the fragment. Case 1 was complicated crown fracture with pin-point bleed ing, that was treated by direct pulp capping with calcium hydroxide and fragment reattachment. Case 2 was in trusive luxation with complicated crown fracture and was treated by pulp treatment and fragment reattachment. Case 3 was uncomplicated crown fracture, and fracture line involved slightly biologic width and treated by reattachment of the crown fragment.
