“…Teleradiographic study was performed in 292 people belonging to the age group of the first adulthood period (21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35), with physiological occlusion of the permanent teeth. The main indicator of the growth type for the gnathic face part was the lower jaw angle as measured between the tangent lines to the branch and the body of the lower jaw.…”

a b s t r a c t -The results of the study and the comparison of the head lateral teleroentgenogram, involving 292 persons (both sexes) in their first adulthood period, featuring physiological occlusion of permanent teeth, helped identify the occurrence of different growth types of the facial area of the head (vertical, neutral, horizontal). The analysis of lateral teleroentgenograms included evaluation of the mandible angle size, the total Bjork angle, the ration between the posterior and the anterior face height, the Ricketts face angle, the angle between the occlusal and mandibular planes, and the angle shaped by the skull base plane and the mandibular plane. The obtained measurements allow stating that most people with physiological occlusion reveal the neutral type of the facial part growth (61.99 ± 2.84%), while the horizontal and the vertical types of growth were observed in 30.48 ± 2.69% and 7. 53 ± 1.55% of the total number of the participants, respectively.

One of the criteria for assessing the maxillofacial area status is the jaw growth. The type of the jaw growth is recommended to be evaluated based on the data obtained through the head teleroentgenogram examination in the lateral projection [4,11,17,25, 28,30,34].

“…Treating mesial occlusion and deep occlusion at the vertical growth type is preferable than treating distal occlusion. The horizontal type of jaw growth makes the treatment of deep and mesial occlusion complicated yet is viewed as favorable in case of treating distal occlusion [2,6,8,10,16,20,22,29,33,35,38,41].…”

Biometric examinations of jaw stone models and tomography images of 310 people (both genders) in their first adulthood stage with permanent teeth physiological occlusion were used to study the morphometric parameters of dental types and dental arches gnathic types in each patient. Odontometric procedure included evaluation of the crowns mesial-distal width involving the calculation of the arithmetic mean, the maximum and the minimum values, in order to estimate the deviations from the mean value (fluctuation). The outcomes suggest that there was no statistically significant difference between the odontometric parameters obtained from men and women. The significant variability in the frontal teeth size in women, compared with men, indicates that the size is only slightly dependent on gender, while is determined by the dental system type. In measurements done without taking into account the dental type, it can be hard to determine sexual dimorphism due to the fluctuating nature of the odontometric indices.

BACKGROUND: The development of modern technologies for the surgical treatment of urological diseases poses new questions for urologists. One of them is to evaluate the effect of transurethral enucleation of benign prostatic hyperplasia on the erectile function of patients. AIM: The aim of the study was to assess the state of erectile function in patients before and after transurethral enucleation of benign prostatic hyperplasia using Doppler ultrasound of the vessels of the penis. MATERIALS AND METHODS: The study included 102 patients with benign prostatic hyperplasia aged 50 to 80 years (average 65 years) with complaints of erectile dysfunction and urinary disorders. All patients underwent transurethral enucleation of benign prostatic hyperplasia: 55 patients with the laser method (HoLEP, group 1) and 47 patients with the bipolar method (TUEB, group 2). The severity of ED was assessed using the IIEF-5 questionnaire (International Index of Erectile Function). To assess the state of blood flow in the penis, ultrasound dopplerography of the vessels of the penis was performed using a vasoactive erection stimulator. The studies were carried out before surgery and 24 weeks after it. RESULTS: The results of ultrasound dopplerography of the vessels of the penis before surgery revealed the arteriogenic type of ED in 18 (17.6%) patients, the venous type in 45 (44.2%) patients, the mixed arteriovenogenic type in 22 (21.6%) patients. In 17 (16.7%) patients ED was regarded as psychogenic. 24 weeks after the operation in patients of both the 1st and 2nd groups, according to the data of the IIEF-5 questionnaire, positive dynamics of the severity of erectile function was noted, regardless of the type of ED. For patients with vasculogenic types of ED, similar trends were noted regardless of the type of surgery. Thus, in patients with arteriogenic and arteriovenogenic ED a significant increase in the maximum systolic blood flow velocity (Vmax) in the cavernous arteries was recorded, while the values of the resistance index (RI) did not change significantly. At the same time, the Vmax values in these patients were initially low before the operation, and after the operation did not reach the reference values. In patients with venogenic ED, there was no significant improvement in penile blood flow, as evidenced by the absence of significant differences in Vmax and RI values. At the same time, the RI in these patients before the operation was reduced, and the Vmax values were in the range of normal values. CONCLUSIONS: The erectile function of patients after transurethral enucleation of benign prostatic hyperplasia improves regardless of the type of operation and the type of erectile dysfunction. Ultrasound dopplerography of the vessels of the penis is a minimally invasive and highly informative diagnostic method that makes it possible to detect circulatory disorders in the penis and assess its state in dynamics during treatment.
