The case of a patient with concomitant regional odontodysplasia, hydrocephalus, and mental retardation is presented. Tooth eruption was retarded, probably because of the presence of a cementum-like substance on the enamel surface as well as the presence of discontinuous odontogenic epithelium that surrounded the affected teeth. Neural damage during intrauterine life is suggested as a likely cause of the dental abnormalities. This hypothesis is supported by the fact that both primary and permanent teeth in the area were affected. It is further supported by the finding of dysplastic dentin.
本文介绍了一例伴有局部牙发育异常、脑积水和智力发育迟缓的患者病例。牙齿萌出延迟，可能是由于釉质表面存在类牙骨质物质以及围绕患牙的不连续牙源性上皮的存在。子宫内生活期间的神经损伤被认为是牙齿异常的可能原因。这一假设得到该区域乳牙和恒牙均受影响这一事实的支持。发育异常的牙本质的发现进一步支持了这一假设。
