The effect of ovariohysterectomy on the parameters of densitometry of the bone tissue of the lower jaw bodies

This article discusses the influence of ovariohystreectomy (OGEC) on the bone mineral density of the lower jaw bodies in puppies. Bone density was studied in the areas of incisors, canines and the third molar. Surgical intervention was performed on animals under general and local anesthesia in compliance with the rules of asepsis and antiseptics. Operative access was performed along the white line of the abdomen. The results of the studies showed that the increase in bone mineral density of the lower jaw branch bodies in ovariohysterectomized dogs 3 months after surgery was higher than in unsterilized bitches. For example, on average, the increase in the area of incisors on both sides was on average 6.1 % higher, canines by 3.25 %, the third molar by 7.25%. At one year of age, there was also an increase in bone mineral density on average in the incisor area by 12.4 % and the third molar by 4.85 %, but in the canine area there was a decrease of 0.1 %. Consequently, X-ray osteodensitometry clearly showed that ovariohysterectomy performed in puppies during puberty led to the filling of the mineral component of the bone tissue of the lower jaw bodies in growing animals.
