- Use of saliva for hormone examinations
- Salivary monitoring of steroid hormone levels has many advantages over the more conventional serum analysis. Non-invasive, simple, safe, stress free and painless allows for multiple collections outside of hospital settings. To see if saliva is valid substitute for serum in assay of testosterone we determined the concentrations of total testosterone in serum and salivary testosterone. Testosterone is androgen, involved in musculoskeletal development, general health and libido. With respect to circadian and seasonal fluctuations of testosterone the sampling was carried out at a standardized time of the day (between 9.00-11.00 a.m) all during November. Saliva and blood samples were collected from 44 boys volunteers ageing 11-19 years and assayed using a highly specific RIA-DSL 4100 assay. (by adapting a commercially available serum testosterone kit - Garanger D.A et al. 1999 for saliva). On average salivary testosterone levels were 1.2 % of plasma levels. We found a highly significant correlations between testosterone in serum and salivary testosterone in the examined group (R=0,73). This high sero-salivary testosterone correlations makes saliva a useful diagnostic tool. Concentration of testosterone in saliva reflect free testosterone circulating in the blood, not bound with proteins marking of which supplies more reliable clinical information than total plasma concentration.

- Uticaj kružnog mišića usana na položaj sekutića
- It is a known fact that forces of small magnitude derived from the soft tissue are closely related with skeleton morphology. Orbicular muscles of mouth have an important impact on the position of frontal teeth. The goal of our research was as follows: 1. To examine electromyographic activity of the orbicular muscles of mouth in patients with neutral occlusion (class I) and distal occlusion joined with incisor retrusion (class 11/2 malocclusion) in the position of physiologic rest and central occlusion during maximal voluntary contraction 2. To examine possible correlation between electromyographic activity of the orbicular muscles of mouth and incisor position in the mentioned groups of patients. Action potentials of the orbicular muscle of mouth were registered at different positions of mandibule. We used intramuscular coaxial electrodes positioned according to Greenfield scheme. The measurement was done on both sides, summed up with ten muscle levels, in 100 patients aged 8 to 12, and one control group with 30 patients with neutral occlusion (class I) and another control group of 70 patients with class 11/2 malocclusion. Results are given in micro volts as average cumulative voltage of action potential amplitudes, which were used to determine changes in the orbicular muscle activity. After statistical analysis of the results, the conclusion is that bioelectric activity of the examined muscles at all measured positions was less significant in patients with distal occlusion, except for lower lip in class 11/2, where this activity was significantly higher. The conclusion is that confirmed changes in action potential of the orbicular muscles of mouth in patients with distal occlusion imply cause -and-effect relationship between muscle function and occlusion. Significantly higher activity of lower lip in malocclusion classll/2 can be considered responsible for angled position of upper incisors. .

- Učestalost ortodontskih nepravilnosti kod učenika II razreda u Knjaževcu
- The aim of this investigation was to determinate the frequency malocclusion the students II Class primary school from Knjazevac. There were analyzed 195 students both sexes of the II Class primary schools from Knjazevac. The results have shown that there has been increase of different orthodontics anomalies. 32 persons only were without orthodontics anomalies. There are 42,56% persons with Class I malocclusion; 34,36% with Class II/1; 31,79% Class II/2 and 2,56% with Class III malocclusion. 44,10% of persons have crowding in the upper jaw; 30,25% have crowding in the lower jaw; 6,15% have protrusion of upper frontal teeth; 2,56% persons have open bite; 27,17% persons have deep bite. .

- Variability of M3 crown formation
- The study aim was to determine the time interval of the first, X-ray detectable M3 sign, as well as the crown formation. Simultaneously, the symmetry of their development in both jaws and bilaterally was monitored. We analyzed 696 orthopantomographic radiographs of children from Niš, 7-16 years old, applying the scheme by Morress. Dental follicles were found in 72.58% of 7-12 years old children, most often in the age from 8 to 10 years. A high percentage (87.10%) of asymmetric development in the jaws was registered, while the asymmetry of the left and the right side was much rarer (30%) and more frequent in the mandible (22%). In 54.63%, the mandible took precedence regarding the M3 development. Crown formation was registered in the age of 9 to 16, most frequently of 12 years (22%). Asymmetric development appeared in 68.5% of the examined population, with the advantage in the maxilla (52.7%). The maxilla had a slight advantage in bilateral asymmetries (18.5% : 15.7%). .

- Variations in crown shapes of maxillary central incisors
- There are 3 types of crown shapes of the maxillary central incisors: type I-rectangular, type II-triangular and type III-oval. 250 study models of orthodontic patients of both sexes (125 males and 125 females) on the Dental Clinic in Nis were tested, with an attempt to determine the existence of variations in the crown shapes of maxillary central incisors. Gingival and incisal width and the crown height were measured by a digital nonius, as well as the proximal sides angle slope (Ø) according to Goose. Slightly more than a half of the examinees (52.40%) have a rectangular shape of the central incizor crown and a third (34%) has a triangular shape. Fewest examinees have an oval crown shape (13.60%). Similar distribution of crown shapes is found according to the examinees sex: a rectangular shape in 52% of boys and 52.80% of girls, a triangular shape in 36.80% of boys and 31.20% of girls and an oval shape in 11.20% of boys and 16% of girls. (Ø) angle is 7.56° in the total examinee sample, which coincides with the European population values. (Ø) angle is 6.95°in the triangular shape (6.51°in females and 7.39°in males); it is 8.20° in the oval shape (8.55° in females and 7.93° in males).

- Variations in cusps number of the lower M1 and M2
- The aim was to investigate the existence of Stomatology in Niš cusps of the lower M1 and M2. Investigation was done on the working models of 400 orthodontik patients (164 males and 236 females), of Clinik of Dentistry in Niš. Results show that the lower molars M1 at the molars group are least subject to reduction so, the largest number of patients in gender group (75,61% boys and 66,95% girls) has a presence in all five basic cusps type M1 5. Type M1 4, where there is complete absence of HLD-hipokonulids has 21,35% of boys and 32,63% of girls. The presence of six cusps was found at 3,05% of boys and 0,42% of girls. Type M2 4 dominates in both sexes (86,59 of boys and 91,1% of girls), while type M2 5 was found in a much smaller percentage (13,41% of boys and 8,9% of girls). It is found the complete absence of a distovestibular cusp-hipoconulids.

- Weight-height relations of the elite athletes in different sports disciplines
- Previous research has shown that for the achievement of top results certain factors such as body height, body mass and proportions of body parts are relevant. Besides the body composition the greatest influence comes from the training process which should be optimally dosed according to the abilities of each athlete. Training process must be accompanied by the corresponding optimal hygiene-diet regime of the athletes. We are of the opinion that optimal body mass of each athlete is com posed of body mass that helps him achieve top results. Thus conceived definition of the optimal body mass is actually the aim of this research. The aim of the re search is to define the aberration in respect to body mass of the elite athletes from the ideal body mass calculated by the formula of Lorenco, De Mole and relative body mass. We have especially aimed at the definition of weight - height relations of elite athletes in different sports disciplines. This re search was conducted on the sample of elite athletes participants of the World and European Champion ships and the Olympic Games obtained from the Internet. We have included 1381 athletes (footballers, volley ball players, waterpolo players, basketball players which be long to the group of team sports). As far as individual sports are concerned, we have included: walkers, swimmers, and gymnasts. The results of this re search show that the biggest aberrations of the body mass from the ideal one calculated according to Lorenc are found in waterpolo players 9,8 and basket ball players 8,6 kg while in other sports disciplines this difference is some - what smaller, namely in volleyball players it is 4,0 kg, swimmers 2,7 kg, footballers 2,7 kg. Walkers have on average smaller weight 5,0 kg while the measured body mass of gymnasts is identical to the ideal calculated body mass according to Lorenc. Some - what smaller abberations were found according to De Mole. .

- Тhe effects of skill-based exercises and a small-sided games program on the motor skills of elementary school students
- The purpose of this experimental study was to determine the effects of a skill-based exercise program on the motor skills of a group of elementary school students. The study was conducted on 90 participants, with an average age of 13, randomly divided into two groups: an experimental [n = 39 (19 girls and 20 boys)] and a control group [n = 51 (24 girls and 27 boys)]. The motor skills were tested at the initial and final measurements. Motor skills were evaluated by 3 flexibility tests, 4 force and strength tests, 4 speed, acceleration and agility tests, and 1 test for assessing cardiorespiratory fitness. After conducting the 16-week program of skill-based exercises and small-sided games related to volleyball, all the parameters of motor skills statistically significantly increased in the experimental group (except for speed among the boys). In the experimental period, the control group did not notice any significant changes in the parameters of the motor skills. The results of this study showed that there were no significant differences in the impact of the two programs on motor skills at the multivariate level but that at the univariate level it was noted that the experimental group of participants following the experimental program had better results compared to the control group of participants in terms of speed and agility tests, for both genders, as well as force and strength among the girls, and cardiorespiratory fitness among the boys. The obtained results indicate that the program of skill-based exercises and small-sided games related to volleyball is suitable for the development of the flexibility, force and strength, and agility of elementary school students.
