[Dental changes induced by radiotherapy: a study of subjects with retinoblastoma. I].
The authors examine the dental and skeletal alterations consequent to the use of radiotherapy as the elective method of treating retinoblastoma, an endobulbar neuroectodermal tumour typical of early infancy. The authors revise the basic concepts of radiobiology and the modifications induced by radiation in developing tissues with reference to both alterations at a microscopic (histological) level and those at a macroscopic level, namely of a morphological and structural nature. In the first part of the study the authors examine the damage to dental structures relating to both developing tissues and damage to mature tissue. The second part of the paper analyses radiation damage on cartilage and bone tissues in the process of formation and the authors present their documentation in the form of iconographic and radiographic material together with an esthetic face analysis performed using Ricketts' [correction of Rickettz's] method in three cases referred to their attention.
