Introduction: Violation of oral fluid mineralization processes, which is determined by the mineralization potential of saliva, is associated with changes in the physicochemical parameters of the oral fluid, particularly its viscosity. The aim of our study was to study mineralization potential and types of microstallation of oral fluid as one of the factors of influence on the cariesogenic situation in the oral cavity of patients with physiological or pathological tooth abrasion. Materials and methods: During the examination of patients’ oral cavity, a comprehensive assessment of tooth hard tissues was performed in order to of study activity and prevalence of the processes occurring in them. Results: Assessing the physico-chemical parameters of oral fluid in patients of the first experimental group, we obtained the following results: the viscosity of saliva in subgroups was 2,17 ± 0,87 for subgroup #1, 1,78 ± 0,57 for subgroup #2, and 2,15 ± 0,86 for #3 subgroups, which did not have a significant difference between the indices within the group. During the research, the number of independent structures of oral fluid in subgroups 1-3 was 1.67 ± 0.86, 1.67 ± 0.77 and 1.57 ± 0.85. Conclusions: Thus, we have established that the mineralizing function of saliva changes when the cariesogenic situation in the oral cavity arises,. This leads to destabilization of the crystalline structure of the oral fluid and indicates the relationship between its structural and mineralizing properties.

Abstract Scelidosaurus harrisonii is an early (Late Sinemurian) armoured ornithischian dinosaur whose remains have, to date, only been recovered from a restricted location on the south coast of Dorset (Charmouth), England. This dinosaur has been known since 1859, but only on the basis of a partial description found in two articles published in the early 1860s by Richard Owen. The original material, discovered in 1858, comprised the majority of the skull and its associated postcranial skeleton, and represents the first ever, more or less complete dinosaur discovered. In addition to the original material, a number of further discoveries have been made at Charmouth; these latter supplement the information that can be gleaned from the original specimen. This article describes the skull of Scelidosaurus. The external surface of individual skull bones in ontogenetically relatively mature individuals displays exostoses, a patina of fibrous or granular-textured bone that anchored an external shielding of keratinous scales. There is a small, edentulous rostral beak, behind which is found a row of five heterodont premaxillary teeth. There is a minimum of 22 maxillary teeth and 27 dentary teeth in jaws of the largest well-preserved individuals known to date. Both dentitions (upper and lower) are bowed medially and are sinuous longitudinally. Maxillary and dentary crowns are tilted lingually on their roots, trapezoidal in outline and have crenellate (coarsely denticulate) margins. Adjacent crowns of teeth have mesiodistally (anteroposteriorly) expanded bases that overlap slightly and are consequently arranged en echelon. The dentitions are flanked by deep cheek pouches. Tooth abrasion is usually discontinuous along the dentition. In one individual nearly all teeth seem to be fully emerged and there is little evidence of abrasion. There is no physical evidence of a predentary, but the presence of this (typically ornithischian) element may be inferred from the structure of the symphyseal region of the dentary. The external narial and antorbital fenestrae are comparatively small, whereas the orbit and temporal fenestrae are large and open. A sclerotic ring was undoubtedly present and supported the eyeball, but it is too poorly preserved to allow it to be reconstructed with accuracy. A prominent supraorbital brow ridge overhangs the orbit. There are three osteoderms: palpebral, middle supraorbital and posterior supraorbital, sutured to the dorsal margin of the orbit. The occiput provides an area for attachment of a pair of curved, keratin-sheathed, osteodermal horns. Epistyloid bones project from the ventrolateral region of the braincase; their distal ends flank the anterolateral region of the neck. Rugose facets on either side of the basioccipital are suggested to have provided attachment sites for the epistyloid bones. Internally, the skull has a deeply vaulted snout and the nasal chambers are roofed by what are here named epivomer bones that appear to have been sutured to the dorsolateral edges of the vomers. Unusually, among dinosaurs generally, an epipterygoid is preserved attached to the dorsolateral surface of the pterygoid; there is no obvious point of articulation for the epipterygoid against the lateral wall of the braincase. A deep pit on the posterior surface of the quadrate of an immature specimen is suggestive of the existence of a remnant of cranial pneumatism. This pit becomes occluded in larger, more mature specimens.

ABSTRACT Abrasion is damage to dental tissue due to foreign objects, such as toothbrushes and toothpastes that contain abrasive ingredients. Abrasion caused by brushing teeth in a horizontal direction and with excessive emphasis. This study aims to obtain an overview of the relationship between the characteristics and habits of brushing teeth with the incidence of dental abrasion in employees of the Al-Ikhlas Masjid Cilandak Foundation in Jakarta. This research is a descriptive study with a cross sectional design. The research sample used total sampling totaling 32 employees of Masjid Al-Ikhlas Foundation. Data collection through direct interviews and observations by filling out checklist sheets and dental abnormalities (tooth abrasion) cards. Data analysis was conducted in univariate and bivariate. The results of univariate analysis showed that the incidence of tooth abrasion was mostly in the high category (53.1%), employee age> 38 years (56.3%), female sex (56.3%), tooth brushing frequency <3 times (62, 5%), and the tooth brushing technique is mostly good (56.3%). The results of bivariate analysis, variables that were significantly associated with dental abrasion events were the frequency of tooth brushing (p = 0.035 and OR = 7,000), and tooth brushing techniques (p = 0.029 and OR = 7.333).

In the article the analysis of the changes in the dentoalveolar system occurring with increased abrasion of the teeth is carried out, the features of these changes and the compensatory capabilities of the dentoalveolar system with pathological abrasion are considered. It was concluded that the observed rearrangements on the part of many structures of the maxillofacial region (jaw bones, temporomandibular joint, teeth, muscles) should be established during diagnosis and treatment should be planned taking into account the morphological and functional changes that have arisen on the part of all elements of the dentition, which will help improve the effectiveness of treatment.

Tooth Abrasion

The high prevalence of non-carious manifestations in patients with celiac disease is described by numerous authors, who are considered as a diagnostic key to atypical forms of celiac disease. The manifestations closely associated with celiac disease include: defects in tooth enamel, pathological tooth abrasion, as a violation of the mineralization of dental crowns, and morphofunctional defects in the hard tissues of the teeth.Materials and methods. We examined 45 patients aged 23 to 36 years with a diagnosis of celiac disease, established on the basis of the results of clinical anamnestic, genetic, instrumental studies, morphological study of a biopsy specimen of the intestinal mucosa.Result. Examination of the dentition of the patients showed that 100% of the examined had pathological abrasion of tooth enamel. Crowded teeth were found in 32 patients. Partial symmetric congenital adentia was diagnosed in 5 patients.Conclusion. The revealed dentoalveolar anomalies can be attributed to oral manifestations of celiac disease, which is a diagnostic criterion for suspected disease.

Wear Tests

This review focuses on the wear mechanisms of natural and restorative dental materials, presenting a comprehensive description and analysis of the works published in the last two decades on the wear at the interface of occlusal surfaces. Different groups of tribological pairs were considered: tooth-tooth, tooth-restorative material (tooth-ceramic, tooth-resin-based-materials, and tooth-metal), and restorative-restorative materials. The lack of standardization of the wear tests impairs the direct comparison of the obtained results. However, it was possible to infer about the main wear mechanisms observed on the different classes of dental materials. Concerning ceramics, their toughness and surface finishing determines the wear of antagonist tooth. Abrasion revealed to be the main wear mechanisms at occlusal interface. In the case of resin-based composites, the cohesion of the organic matrix and the nature, shape, and amount of filler particles greatly influences the dental wear. The protruding and detachment of the filler particles are the main causes of abrasion of antagonist enamel. Metallic materials induce lower wear on antagonist enamel than the other classes of materials, because of their low hardness and high ductility. Most of the studies revealed plastic deformation and adhesive wear as the main wear mechanisms. Overall, more research in this area is needed for a better understanding of the mechanisms involved at the occlusal surfaces wear. This would be essential for the development of more suitable restoration materials.
