摘要：The data of bone mineralization range in dogs during the deciduous teeth change are presented in the article. Densitometry is a progressive and minimally invasive methods using in modern dentistry to determine bone mineral density. Five mongrel dogs at the age of 3 months were x-ray tested during the period of occlusion shifts per every 10 days for 3 months. It is found that a significant increase in bone density is registered in experimental animals during teething. It is established that the relative mineral density varies by 26.1% in the front teeth region, by 24.8% in canines' region and by 38.6% in the region between the second and third premolars in dogs. The average increase of the lower jaw bone mineral density has averaged about 26% due to permanent occlusion forming processes and skeletal growth in dogs.
