Abstract：AIM: To observe the distribution of MSX1 during permanent tooth root development of dog and evaluate the effect of regulation on tooth root patterning. METHODS: During permanent tooth root formation of dog MSX1 mRNA was detected by in situ hybridization. RESULTS: During tooth root patterning, expression of MSX1 was found not only in dental papilla of the apical area, dental sac and odontoblasts, but also in dental attachment apparatus such as cementoblast, periodontal supporting tissues and alveolar bone. CONCLUSION: MSX1, as a key transcription factors during tooth development, is likely to participate in regulating the formation of tooth roots.
