More than two-fifths of the examined patients have a mandatory need for orthodontic treatment if the DAI scores are the main screening tool. Orv Hetil. 2018; 159(9): 352-356.

The advantages and limits of echography in the performance of percutaneous nephrostomy and nephrostolithotomy are described, based on our own cases.

The authors elaborated a new device permitting to perform internal urethrotomy for urethral stricture in an anterograde way, even in cases where optical retrograde urethrotomy could not be applied. The new device is similar to a bladder biopsy forceps with a diameter of Ch 5. Its cutting knife is movable. It can be used with Sachse's urethrotome, inserting it in its guide channel with closed knife and passing it through the stricture. By opening the knife, anterograde urethrotomy can be performed. Out of 145 urethrotomies, this method was utilized in only 3 cases.

Introduction: The incidence of congenital hypodontia is increasing in daily practice. Early diagnosis of this dental disorder and the associated skeletal malocclusions is crucial for successful and stable final rehabilitation. Aim: Comparison of cephalometric findings of patients with hypodontia of 1–4 teeth with the measurement results of the control group without teeth agenesis. Material and method: We evaluated the lateral X-ray of 41 patients with 1–4 teeth agenesis selected from patients referred for orthodontic treatment to the Orthodontic Department of the University of Medicine and Pharmacy from Târgu Mureş within a two-year period. The results were compared with the values of the age and sex matched control group. Results: Bilateral upper incisor and lower bicuspid were missing in most of the hypodontia cases. When looking at the NSGn angle predicting the growth direction of the mandible, statistically significant differences were found between the male (p = 0.012), the front (p = 0.010) and the hypodontia group (p = 0.024) and the control group. Regarding the ANB angle, which shows the sagittal position of the maxilla to the mandible, statistically significant differences were found between the subgroups (women, men, anterior or posterior hypodontia) and the control group. Conclusion: Larger number of skeletal class 3 and vertical hypodivergent tendency were observed in the hypodontia group. Orv Hetil. 2019; 160(6): 214–219.
