The aim of this paper was the evaluation of three teeth extracted from the cleft of primary and secondary palate and from its surrounding. Investigations concerning surfaces of sagittal cuts of teeth observed in light microscope and in scanning microscope (type Jeol-JSM-35-CF) were made after it was covered by gold in vacuum. Morphological abnormalities of enamel and dentine were observed only in tooth extracted from the cleft. No abnormalities were observed in teeth extracted from the surrounding, of the cleft. Structural and substructural abnormalities of the tooth extracted from the cleft were probably connected with environmental changes during appropriate stages of its development.


Celem pracy był opis histologiczny trzech zębów usuniętych z rozszczepu podniebienia pierwotnego i wtórnego oraz z jego otoczenia. Badania dotyczyły powierzchni po strzałkowym cięciu zęba. Oceniono je w mikroskopie świetlnym i skaningowym (typ Jeol-JSM-35-CF) po pokryciu ich warstwą złota. Nieprawidłowości morfologiczne szkliwa i zębiny stwierdzono tylko w zębie usuniętym z rozszczepu. Nie wykazano nieprawidłowości histologicznych w zębie usuniętym z otoczenia rozszczepu. Nieprawidłowości anatomiczne i histologiczne zęba usuniętego z rozszczepu były prawdopodobnie związane ze zmianami środowiskowymi podczas odpowiednich stadiów jego rozwoju.
