The main prerequisite for a successful treatment of pulp disease in apex periodontium is knowledge of morphological characteristics of root canal system, especially one third of his apex. The aim of this work was to define the exact distance of the main and auxiliary openings from the top of medial and distal roots of the first lower permanent molars. Methods: as a research material it was used a hundred extracted first lower molars of the patients of both gender, divided into three age groups. The analysis of the one third of apex was done with the help of binocular magnifying glass and digital roentgenography analysis half of the samples, which were filed with capillary contrast. Results: The results obtained showed that the longest average distance of the main opening from the top of medial root was 0.84mm, and the shortest was 0.61mm; while for the distal root the longest average distance was 0.89mm, and the shortest was 0.62mm. Maximum distance of the auxiliary openings from the top of medial root in the first group was 3.5mm, and the maximum distance of the auxiliary openings from the top of distal root was 2, 5 mm. The results obtained with digital rentgenography showed that the longest average distance of the main opening from the top of medial root was the one noticed in the second age group (0.91mm) then the one from the first group (0,83), and the shortest one in the third age group (0,71mm); as for the distal root: the longest average distance of the main opening from the top of the root was noticed in the third age group (0,95mm) then in the first (0,90mm) and than shortest in the second age group (0,89mm). Conclusion: The distance of the main and auxiliary openings from the top of medial and distal root of the first lower molar varies in the range from 0 to 3,5mm and it depends on the tooth age. .

Therefore, we have to rethink the linguistics and identity changes arising from such changes. In a society that points more and more to the digital environment as an effective interactive space, the one which embodies individuals in an increasingly way with mobile technologies, it becomes necessary to discuss the inclusion of other layers of society and age groups in this digital environment. Hence, this paper aims to evaluate texts produced by the students that are part of the project GLADs 2013 and from that to investigate which are the specificities of this group in genre acquisition and digital universe. For this objective, the current research is based on the theoretical contributions of Scholes (2011), Burke (1945) and Jenkins (2009).Keywords: Writing. New media. Inclusion.

Introduction Knowledge of the complexity of the root canal system in lower first molars and particularly the apical part of the root affects significantly the realization and success of the endodontic procedure. Aim The aim of this paper was to determine the thickness of the primary and secondary dentine around the main foramen of the mesial and distal root of the lower first permanent molar in teeth of various ages. Material and Method Fifty extracted lower first molars of both male and female patients extracted for various reasons were used in the study. All teeth were allocated to three age groups: under 25 years old (15 teeth), between 26 and 50 (20 teeth) and over 51 years old (15 teeth). After access cavity preparation, canal orifices were enlarged and root canals were explored using hand K-files #10. Using a diamond disc, the root tip was then cut off in the area of the apical foramen. Dentine thickness was determined using a complex configuration comprising of several devices which were interconnected by software. These included a polarised microscope (Leica DMLSP), a digital camera (Leica DC300) and a scanner. Results The results showed that the greatest mean thickness of the primary dentine was in the mesial root of the first lower molar in the first age group (0.177 mm), followed by the third (0.145 mm) whilst the least mean thickness was observed in the second age group (0.141 mm). In the distal root, the mean thickness of the primary dentine was in the second (0.175 mm), then the first (0.138 mm) and finally the third group (0.100 mm). The mean thickness of the secondary dentine in the mesial root was observed in the second group (1.25 mm), followed by the third (1.11 mm) whilst the least mean thickness was found in the first age group (0.95 mm). The mean thickness of the secondary dentine in the distal root was observed in the second group (1.26 mm), then the third (1.18 mm) whilst the least mean thickness was found in the first age group (0.99 mm). Conclusion The obtained results suggested that the mean thickness of the primary dentine in the mesial and distal roots was comparable. For both mesial and distal roots, the greatest mean thickness of the secondary dentine was observed in the second age group.

This study aimed to identify the anaerobic capacity level of a sample of Omani children. The sample included 197 children between the ages of 9 to 13 years. The Running-based Anaerobic Sprint Test (RAST) was used. The sample was divided into five groups. The first group comprised the nine-year olds (19 children), the second group comprised the ten-year olds (22 children), the third group comprised the eleven-year olds (52 children), the fourth group comprised the 12-year olds (43 children), and the fifth comprised the 13-year olds (61 children). The results showed that the anaerobic capacity level improved during the stages of growth. The level of improvement achieved in 13-year old children was the highest compared to the other age-groups (P S 0.000). This improvement was not at a steady rate. It occurred through booms that coincided with growth which appears in practice through the evolution of not only the level of values on the amount of effort, but also in the level of some related motor skills. It showed a positive correlation between the values of the anaerobic capacity level, the time of running 100 meters and vertical jumping (p S 0.01). Accordingly, this phase can be considered one of those booms. Key words: anaerobic capacity, (Running-based Anaerobic Sprint Test (RAST), Omani children, the 100 meters running, vertical jumping.

Smoking is a significant risk factor of chronic noncommunicable diseases. Smoking prevalence is variable in different populations. A study of the prevalence of this risk factor allows to estimate its contribution to the development of cardiovascular pathology, to plan the necessary amount of medical care for people using tobacco, and to determine the effectiveness of prevention activities in the region. As a result of the study, smoking frequency in population of the Irkutsk region older 18years of age or over was established as 29.5%. The number of smokers increased with age, reaching maximum value of 38.6% in the group 30–39 years. Male smokers made maximum in the age group 30–39 years, women – in the age group of 18–19 years. The average age of smokers was 34 years, the one of nonsmokers – 43 years. The age difference was 9 years, and it was lower in the group of men than in the group of women (5 and 11 years, respectively). The number of the smoking men were 3 times larger, than women: 50.2% and 13.5%, respectively. Among persons with arterial hypertension, 22.1% were smoking with the maximum frequency of smoking in age groups from 20 to 49 years. These figures point to a considerable problem of smoking in the region.

<p>The Banded Iron Formation (BIF) in Bundelkhand craton (BuC) occurred as supracrustals associated with TTG’s, amphibolites, calcsilicate rocks, and quartzite within the east-west trending Bundelkhand tectonic zone (BTZ). The BIFs near Mauranipur do not show any prominent iron-rich and silica-rich layer band and are composed of garnet, amphibole, quartz, and magnetite. The volumetrically dominant monoclinic-amphiboles are grunerite in composition. X<sub>Mg</sub> of grunerite varies between 0.39-0.37. The garnets are Mn-rich, the X<sub>Spss</sub> of garnet ranges from 0.26-0.20, X<sub>Pyp</sub> and X<sub>Grs </sub>vary between 0.10-0.06 and 0.07-0.05, respectively. P-T pseudosection analysis indicates that by destabilizing iron-silicate hydroxide phases through a series of dehydration and decarbonation reactions, amphibole and garnet stabilized in BIF at temperature 400-450°C and pressure 0.1-0.2 GPa.</p><p>Massive type BIFs have monazite grains that vary from 10 to 50 µm in size, yield three distinct U-Th-Pb<sub>total</sub> age clusters. 10-20 µm sized monazite grains yield the oldest age, 3098±95 Ma. 2478±37 Ma average age is obtained from the second group, which is relatively larger and volumetrically predominant. The third age group of Monaiztes gives an age of 2088±110 Ma. ~3100 Ma monazite suggests the older supracrustal rocks of Bundelkhand craton, similar to those obtained from Singhbhum and the Dharwar craton. The 2478±37 Ma age is constrained as the timing of metamorphism and stabilization of BuC. The third age group, 2088±110 Ma probably associated with renewed hydrothermal activities, leading to rifting and emplacement of mafic dykes in BuC.</p>

Introduction. Dental caries has been one of the oldest but still one of the most common oral diseases in humans. Even though it has been almost eradicated in developed countries due to increased fluoride use, adoption of proper oral hygiene habits and systematic implementation of preventive programs, caries remained one of leading oral diseases in developing countries. Epidemiological data about the prevalence of caries is very important for prediction of need for dental care, number of dental care providers as well as financial aspect. The aim of this study was to determine dental status and indicate dental treatment need in adults of the municipality of Foca, Republika Srpska (Bosnia and Herzegovina). Material and Methods. The study included 244 randomly selected residents (131 males and 113 females) from the municipality of Foca which were divided into three age groups: 20-29, 30-39 and 40-49 years. Dental status and need for dental treatment were determined in accordance to the criteria and methodology of the World Health Organization. Results. Mean value of DMFT index was 12.7 for the first age group, 16.4 for the second and 20.5 for the third age group of respondents. Dominant components in the first group were restored and carious teeth while in the third age group number of extracted teeth dominated. Also, in the third age group of respondents need for one and two or more surfaces fillings was significantly lower (p<0.01), but need for removable dentures was significantly higher (p<0.01) as compared to other two groups. Conclusion. These results indicated high value of DMFT index in adult population of the municipality of Foca.

Objectives: Molar-Incisor Hypomineralization (MIH) is a condition of hypomineralized enamel of systemic origin affecting first permanent molars and frequently permanent incisors. It is considered a global problem and data from South-East Asian countries, including Malaysia are lacking. Hence the aim of this study were to investigate the distribution and severity of MIH in a group of children aged 7-12 year olds attending pediatric dental clinic at Faculty of Dentistry, Universiti Teknologi MARA (UiTM), Malaysia. Study design: Hundred and fifty four children age 7-12 year-old with mean age of 9.14 ±1.682 had their first permanent molars and permanent incisors were examined at Faculty of Dentistry, UiTM using European Academy of Paediatric Dentistry 2003 (EAPD) criteria for diagnosis of MIH. Children at least one first permanent molar affected were considered as having MIH. Data were recorded and statistically analysed using descriptive analysis and Chi square test. Results: Twenty six of the total examined children (n=154) had MIH (16.9%). There was no statistical difference between males and females in the prevalence of MIH. However, a statistical significant difference was found by age groups. The first permanent molars were more frequently affected (58%) as compared to permanent incisors. Mandibular molars were to have the highest rate of MIH (15.5%). The right and left sides were equally affected. Mild defects were the most frequent lesion type (96.6%). Conclusions: This study revealed that MIH is a common condition (16.9%). Molars were more frequently affected than incisors with mild defects were the most common lesion status. Further studies on this defect amongst Malaysian children are worthwhile.

Abstract. The aim of this study was to determine whether the classification of local Spanish breeds of dogs, based on morphological traits, matches or differs from the classification based on the dogs' breeding goals. A total of 15 biometric measurements and 10 functional indices were obtained in 1 365 dogs (709 females and 656 males). The dogs we measured belonged to 16 different breeds, 14 of which were officially recognized by the Spanish Royal Canine Society. Similar average values of morphometric traits and indices (P<0.001) were obtained in both sexes: the Ratonero Bodeguero Andaluz was the breed with the smallest format and the Pyrenean and Spanish Mastiff, the largest. In the case of the Fédération Cynologique Internationale (FCI) groups, significant differences (P<0.001) for morphometric traits were found, and in both sexes, the third group was the one with the smallest format and the second group, the largest. The differences obtained were more marked between all groups than within groups, and the morphological characteristics were similar, in accordance with the purpose for which the breeds were bred. Therefore, the existence of a morphologic pattern is accepted both in the breeds and the functional groups. Two as yet officially unrecognized breeds, the Orito and Paternino Hound, must be included in the fifth and the first FCI groups, respectively. When the Orito Hound is recognized, it will be added to the fifth FCI group and the word »hound« will be deleted from the name Paternino breed.
