[Structure of the dog periodontium during milk and permanent occlusion].

The state of dog parodont during milk and permanent occlusion was studied by morphological methods in 8 animals. It was established that the structure of parodont of milk and permanent teeth has features characteristic for each type of occlusion. One of the important distinctions of parodont structure during milk occlusion is the presence of osteoclasts especially in the sites of root resorption. Close attachment of roots of milk teeth to follicles of permanent teeth should be taken into consideration in orthodontic correction of milk tooth position.
