ALTERATIONES STRUCTURAL IN LE INCISORES DE RATTOS TRACTATE CON CORTISONA.—Un total de 400 mg de cortisona administrate a rattos in le curso de un periodo de 8 dies resultava in marcate effectos in le disveloppamento del incisores a base de un comparation con un gruppo de animales de controlo. Le alterationes observate esseva primarimente un disorganisation e abassate differentiation del odontoblastos, si ben como un formation excessive, intra le pulpa, de un osseoide tissu dur que esseva ric in inclusiones cellular e vascular. Iste tissu dur monstrava certe similitudes con le osso pulpal trovate in le dentes de scorbutic porcos de India.
