ABSTRACT
Objective:
To study the ultrastructural changes of the junctional epithelial after dental preparation.Methods:
Junctional epithelium (JE) of left premaxillary teeth was detached by diamond bur in 8 rabbits (group 1) and by surgical knife in another 8 rabbits (group 2). JE of the right teeth without treatment was used as the controls. 4 animals in each group were sacrificed 1 and 2 weeks after operation respectively.Samples were prepared for transmission electron microscope observation.Results:
In the two tested groups reattachment was observed 2 weeks after operation,degeneration of mitochondria in JE cells and destruction of basement membrane were observed. No significant difference was observed between group 1 and group 2.Conclusion:
Dental preparation may result in ultrastructural changes of JE cells.
