ABSTRACT
Objectives:
To investigate the relationship between calcitonin gene-related peptide(CGRP) in rat dental pulp and tooth movement.Methods:
The first maxillary molars in 36 SD rats were moved mesially by orthodontic force,18 were examined 3,7 and 14 day after application of the appliance whereas another 18 rats were observed 7,14 and 28 days after removal of the appliance respectively.6 control rats were without treatment.Then,CGRP immunoreactivity was demonstrated by indirect immunoflurescence on frozen sections of dental pulp samples.Results:
3,7 and 14 days after application of orthodontic force, the CGRP containing nurve fiber counts in each pulp were 17.57?4.42,24.04?3.55 and 21?4.11 respectively,those in the control pulps were 8.03?4.49. 7,14 and 28 days after removal of the appliance, the counts were 19.23?5.23,18.23?5.08 and 8.12?5.01 respectively.Conclusions:
CGRP immunoreactive nerve fibres may take an active part in tissue responses in pulp tissues during experiment tooth movement.
