[en] Positive contrast radiography of both shoulder joints with different concentrations of Uropolin (containing 1.6 g sodium amidotrizoate and 10.4 g meglumine amidotrizoate in 20 ml ampules; Polfa, Poland) has been performed in six dogs, divided into 3 groups. The first group was injected with 20% Uropolin, the second - with 30% Uropolin and the third - with 30% Uropolin and 0.2 ml 0.1% adrenaline hydrochloride. Shoulder radiographs were performed 2, 5 and 10 min after the injection of the contrast medium in mediolateral and craniocaudal views. The quality of radiographs was assessed visually using a four score system for five independent parameters in both views. The results showed a better quality of mediolateral radiographs 5 minutes after injection of 30% Uropolin (average score 12.5) compared to 20% Uropolin (average score 8.5), at p<0.05. The addition of 0.1% adrenaline hydrochloride to 30% Uropolin resulted in a better quality of arthrographs up to 10 minutes following the administration (average score 10 compared to 8.5 in the group with independent application, p<0.01)

[en] The main radiological features were vizualization of the cervical and the thoracic parts of the oesophagus, extension of the shadow of the dilated part to the heart, but without overlapping, position of the shadow of the dolated part mostly to the lift in ventrodorsal view. All those features were confirmed in a contrast radiological study

[en] The experiments were performed on 7 dogs aged between 2 and 4 years weighing 12-16 kg in the period October 1998- January 2000. After anaesthesia, the following dental procedures were accomplished; performance of a dental avulsion, endodontic treatment, apical dentotomy, tooth replantation and fixation with an orthodontic splint, figure-of-eight wire ligature and photopolymer. The treatment was effective in 71.4% of experimental replantations of incisors and the replanted teeth persisted for more than 8-9 months. The radiological survey showed that the regeneration began as early as the first post replantation days. In the period between days 30-45, a bone bridging was observed and the regeneration was complete by the end of the second month

[en] The treated bone defects were compared clinically and radiologically. After a 3-month period of survey, the best results were obtained in the group treated with partially demineralized bone matrix, enzymatically processed and lyophilized dura mater and mucoperiosteal flap. The placement of titanium screw dental implants did not impair the guided bone regeneration, that was confirmed by their good osteointegration
