ABSTRACT

Objective:

To evaluate the physiological roles of bmp3,bmp4 and bmp7 during the formation of permanent tooth roots in dog.

Methods:

The expression of bmp3,bmp4 and bmp7 mRNA at different stages of the development of permanent tooth roots was examined by in situ hybridization in 3 dogs aged 12-18 weeks.

Results:

bmp3 was found in dental sac surrounding the germs at the early stage of tooth root development, and in cementoblasts and periodontal cells at the later stage. bmp4 was found in odontoblasts, dental papilla and osteoblasts. bmp7 positive signals was found only in epithelial cells of root sheath around cervical circulus at early stage, then located in cementoblasts and odontoblasts at later stage.

Conclusion:

The spatiotemporal expressions of bmp3,bmp4 and bmp7 are widely diverse, indicating that they participate in the regulation of tooth root development.
