Timely teething is one of the most important indicators of the harmonious development of the dentoalveolar system, which is determined by the correct (physiological) position of the teeth in the dentition, ensuring the optimal shape and function of the temporomandibular joint, the work of the chewing muscles, the height of the lower part of the face, and aesthetics of a smile. Retention of individual teeth is often the reason for the formation of anomalies in the dentition, their closure, functional and aesthetic disorders. An urgent problem in modern dentistry is the problem associated with the development of third molars. According to the results of the analysis of 3000 orthopantomograms of the jaws of patients 7–25 years old with dentoalveolar anomalies, the spatial arrangement of the primordial of the third molars relative to the buttresses of the upper and lower jaws was studied. It was found that the buttresses on the upper jaw are vertical and do not interfere with the correct eruption of the third molars. The buttresses located near the primordial of the third molars on the lower jaw contribute to the retention of the third molars due to the change in inclination during the formation stage.

Genetical Control

The normal mouse has three molars in each jaw. Of these, the third is by far the smallest. Indeed, it is not constant, and its absence in wild mice from widely separated localities has been reported by various authors (Barrett-Hamilton, 1910; Searle, 1958; Deol, 1958; Harland, 1958; Herold & Zimmermann, 1960; Berry, unpublished). Absence of third molars occurs in varying frequencies in most mouse populations which have been adequately sampled, and usually the upper rather than the lower third molars are more strongly affected. Absence ofthird molars (predominantly in the lower jaw) occurs frequently (about 18 per cent.) in the CBA/Gr inbred strain of mice (Grüneberg, 1951) and less commonly (about 3 per cent.) in the A/Gr strain (Searle, 1954a), but it is virtually absent from the C57BL/Gr strain of mice. These inter-strain differences are evidence that the condition is, to some extent at least, under genetical control

The aim was to determine the morphometric parameters of the maxillofacial area of Omsk young men of 18-20 years of age according to the teleroentgenography of the head (in a lateral projection), taking into account the indicators of cephalometry and anthropometry, to identify regional constitutional features of quantitative values.Material and methods. A cephalometric and somatometric examination of 26 Omsk Slavic young men of 18-20 years of age without concomitant pathology was performed, supplemented by an X-ray examination of the head (to obtain teleroentgenograms in a lateral projection). The analysis of teleroentgenograms was carried out in the online service Mave Cloud.Results. According to the results of anthropometry, the longitudinal and transverse dimensions of the young men's heads, the zygomatic diameter and the full height of the face were assessed; the indicators of body growth, body weight, chest circumference and transverse chest diameter were determined. These indicators were used to calculate the indices. The value of the facial index was 81.86 (79.31; 88.88), the value of the head index was 76.65 (74.27; 79.47), the Rees-Eisenck index corresponded to 97.58 (94.62; 107.48), the Rohrer index was 13.34 (12.07; 15.48), the Pinier index was 11.1 (-10; 22), the Quetelet II index was 23.33 (22.03; 27.71). When analyzing teleroentgenograms, it was revealed that the values of some parameters in Omsk young men of 18-20 years of age differ from the values of the «norm». Thus, the indicators of the lower jaw length (Go-Gn), the ratio of the body of the lower jaw length to the length of the anterior base of the skull (Go-Me/S-N), the length of the posterior base of the skull (S-Ar), the height of the branch of the lower jaw (Ar-Go), the ratio of the heights of the face (S-Go/N-Me), the angle between the axis of the lower incisor and the plane of the lower jaw (IM IMPA) have greater values than the «norm»; and the figures of the angles sum according to Bjork (∠SUM Bjork), mandibular angle (∠Ar-Go-Me), maxillary angle (∠N-Go-Ar), upper jaw inclination angle (∠NSL-NL), lower jaw inclination angle (∠NSL-ML), intermaxillary angle (∠NL-ML), the angle between the lower jaw plane and the Frankfurt horizontal (∠FMA), have values less than the «norm». The values of the saddle angle (∠N-S-Ar) differed in young men with euryprosopic and leptoprosopic facial forms. The quantitative values of the lower jaw angle (ArGo-Me) and the upper jaw angle (N-Go-Ar) differed only in the representatives of the dolichocephalic and mesocephalic forms of the head.Conclusion. Quantitative values of cephalometric and somatometric parameters in Omsk young men of 18-20 years of age have distinctive features. Individual parameters of the maxillofacial area (according to teleroentgenograms) differ in persons with dolichocephalic and mesocephalic forms of the head and in the representatives of euryprosopic and leptoprosopic forms of the face.

Sucking the thumb is considered an inborn reflex. However, after the age of four (in case of emotional instability and anxiety) this reflex becomes a bad habit. This vicious habit is one of the most important etiological factors which determine the Angle Class II/1 malocclusion. The research relied on the analysis of the photos of schoolchildren aged 6 to 14 who admitted the persistence of this bad habit and also had Angle Class II/1 malocclusions. We analysed the photos of the face and of the exobuccal and endobuccal profiles. We have chosen two cases from the researched group to highlight the clinical aspects of Angle Class II/1 malocclusions. The patients maintained the bad habit of sucking the thumb which, accompanied by other etiological factors, led to a skeletal disequilibrium. Thus, many modifications may appear such as: upper jaw prognathism and lower jaw retrognathism with a sagittal inocclusion as well as changes of the physiognomy specific to Angle Class II/1 malocclusions. In the case of Angle Class II/1 malocclusions, the coexistence of hereditary and functional pathologic factors generally leads to skeletal and neuro-muscular modifications with aesthetic repercussions.

Abstract Lepisosteids or gars constitute a very special neopterygian group, with seven living species in two genera: Lepisosteus and Atractosteus. They live in freshwaters from the eastern part of North America and Central America. A new lepisosteid, Oniichthys falipoui gen. nov., sp. nov., is described on the basis of two well preserved specimens. Although the type locality is unknown, information provided by the fossil collector, the type of preservation of the specimen, and the nature of the attached matrix indicate, with confidence, that it comes from the Kem Kem beds of southern Morocco (fig. 1). The Kem Kem beds are rich fossiliferous horizons, exposed along the face of an escarpment extending from the north of Erfoud town to the Kem Kem area. The age of these outcrops is still debatable being considered as ?Albian in age [Forey and Grande, 1998] or regarded as Cenomanian, due to their elasmobranch assemblage [Sereno et al., 1996]. Oniichthys falipoui shows several derived characters of gars such as an elongated ethmoid region, an upper jaw formed by a chain of tooth-bearing bones, a joint between the quadrate and the lower jaw lying far forward, in front of the orbit and a large splint-like quadratojugal overlying the horizontal branch of the preopercle. O. falipoui shares with the primitive gar, Obaichthys decoratus, from the ?Albian Santana Formation of Brazil, the presence of toothed maxillaries, although in the Moroccan taxon, the maxillaries are anteriorly fused with infraorbitals. This structure confirms that, at least, some of the "infraorbital chain" bones bear maxillary teeth, fused to them during ontogeny. Discussion of characters leads to regard O. falipoui as more derived than Obaichthys, and to place it as the sister-group of Lepisosteus-Atractosteus.

Oligodontia is a rare congential disorder of dental anomalies that can occur either as an isolated finding or as part of a syndrome. It is defined as agenesis of six or more teeth excluding the third molars. It is commonly seen in permanent than in deciduous dentition. Patients suffering from oligodontia may present with complex problem such as dental and facial disfigurement. Management of those cases generally requires multidisciplinary approach to restore esthetic and function. This paper reports a rare case of oligodontia in an 18 year old adult female patient who has been missing eight permanent teeth excluding the third molars, clinically and radiographically.

Fractures are one of the most common components in multiple and associated injuries. Fractures of the lower jaw are observed in 76%, of the upper jaw in 24%, a fracture of the zygomatic-orbital complex in 12%. The actual problem of modern traumatology is the violation of reparative osteogenesis with injuries combined with facial trauma. The duration of the consolidation of fractures is determined by the degree of microcirculation disorders in the fracture zone, changes in cellular and coagulation hemostasis and mineral metabolism. In this connection, increasing the effectiveness of treatment of fractures of the bones of the face on the basis of early diagnosis of vascular and hemostasiological changes is of great importance for practical health care.

The article discusses the important problem of the presence and location of the primordia of third molars and the possibility of their eruption without affecting the dentition. The problem is relevant and is being studied by domestic and foreign specialists from different angles with the use of various diagnostic techniques. This article is based on the analysis of the most accessible and most frequently used X-ray diagnostic method – the panoramic X-ray.The aim was to study the prediction of eruption of the lower third molars depending on their position relative to the “stress axis”.84 panoramic images of the patients aged 12‒25 years were analyzed. To study the OPTG, the method of Fishchev et al. (2012), which determines the position of the lower third molars relative to the “stress axis”, and Demirjian’s modified method (1973), which determines the stage of their formation, were used. The data were processed statistically.The results are presented in tables and diagrams, as well as in correlations. Their interpretation is discussed. These data allowed us to draw conclusions about a significant change only in the angle of inclination and the stages of formation of the roots of the third molars of the lower jaw, about the absence of changes in the gonial angle and the position of the studied teeth with age. At the same time, it was found that the location of the coronal part of the third molars below the “stress axis” does not worsen the prediction of their eruption.
