The aim of this literature review is to present the main advantages of pre-prosthetic preparation of the masticatory system with occlusal appliances. The possibilities for attaining muscle relaxation at the achieved centric condyle position in the temporomandibular joints are discussed. The advantages, in terms of hard dental tissue protection, the diagnostic value and the psychoprophylactic effect, are considered. The wide-ranging benefits of the use of occlusal appliances in bruxism- and bruxomania-related craniomandibular dysfunctions are indisputable and represent a current scientific interest.

Definitions of terms masticatory system and vocal organs are used as introduction to analysis of their relations. Articulation involves masticatory and respiratory systems the primary functions of which are different from generation of sounds and particularly speech. However, proper and consistent action of these systems is indispensable for generation of understandable words. The paper presents basic properties of structure and functions of masticatory system at various levels of its development. Particular attention was concentrated on all elements of mascicatory system (lips, dental arches, tongue, palate, and muscles of temporomandibular joints) on shaping mechanisms of speech.

Introduction. A lack of appropriate adhesiveness is one of the biggest problems in the restorative dentistry today and the main cause of the microleakage between restorations and hard dental tissue. The aim of this study was to assess the adhesiveness of two different glass ionomer cement restorations class V on the hard dental tissue using the SEM analysis and dye penetration test. Material and methods. The study included 80 extracted teeth for orthodontic reasons (premolars and molars) in both genders and different age. On the vestibular and oral side of the teeth, adhesive preparations class V were done (size 3?2?2 mm). On the vestibular preparation, GC Fuji II was applicated and GC Fuji II LC-improved on the oral side. The quality of the adhesiveness between restorations and hard dental tissue was evaluated using the SEM analysis and dye penetration test (0.5% basic fuxsin). Linear penetration of the dye was observed using 10 times magnification. Results. The results showed that microleakage was presented with both materials but a ratio was less with Fuji II LC compared with Fuji II. Also, the microleakage was less on the occlusal parts of the restorations than on the gingival, with both materials. Microleakage was noticed in 93.44% teeth with Fuji II GJC restorations with index of microleakage of 148 on all edges. Fuji II LC GJC restorations showed microleakage in 68.4% teeth with index of microleakage 75 on all edges. The SEM analysis showed that both glass ionomer materials had better adhesiveness to the enamel than to the dentin. The average gap length between Fuji II LC and dentin was 9 ?m and Fuji II 17 ?m, respectively. Conclusion. Better adhesiveness to the hard dental tissue was achieved with materials of the newer generations, resin modificated glas ionomer cements.

Computerized tomography (CT) and magnetic resonance (MR) imaging of the temporomandibular joint are often not a routine part of a dental patient's pain and clinical evaluation. As a result, the most poorly understood region within the masticatory system is the temporomandibular joint foundation. Unfortunately, patient care and occlusal management are often compromised because of a lack of insight into the relationship between the anatomy of the temporomandibular joints and the occlusion. This chapter's four distinct sections review the key concepts about the temporomandibular joint foundation anatomical structures, detail structurally intact and structurally altered temporomandibular joint anatomy, clarify how structurally altered temporomandibular joints influence occlusal function, and classify the stages of temporomandibular joint structural degeneration. The concept of joint-based malocclusion is explored with numerous temporomandibular joint foundation anomalous software renderings, and sample CT and MR images, which together illustrate in detail how soft tissue and bony abnormalities in a structurally altered temporomandibular joint can create distortions in the occlusion. Lastly, the chapter addresses the specific requirements a clinician must technically master to perform a comprehensive CT or MR examination.

Abstract Background Mandibular deviations are common clinical complaints. The orthodontic or orthognathic treatment of mandibular deviations is tricky because a comprehensive diagnosis, especially a functional one, is difficult to make. A inaccurate diagnosis may lead to a compromised and unstable treatment outcome. Case presentation This article describes the diagnosis and treatment of a woman with a mandibular deviation and facial skeletal asymmetry. By eliminating the disharmony of the arch form with elastics and bite turbos, her esthetic and functional outcomes improved. Cone-beam CT (CBCT) and Joint Space Index (JSI) analyses served as the diagnostic approaches and outcome evaluation methods before and after treatment. Conclusions A condyle position displacement could be an indication of functional deviation. JSI analysis is a quantitative and convenient choice to compare condyle relative positions.

Salthill Quarry, Clitheroe, Lancashire (Mississippian, early Visean, Chadian) is a Site of Special Scientific Interest on the basis of its diverse fauna of invertebrates preserved in a Waulsortian mud mound setting. Important new specimens are described from the limestones and thin mudstones of the Hodder Mudstone Formation, on the southern margin of the quarry. A rare echinoid, archaeocidarid? gen. et sp. indet., is incomplete, but unusually retains the original curvature of the test. A columnal of Bystrowicrinus (col.) westheadi Donovan was derived from a radicular runner and has a dense cluster of radice scars on one side only. The columnal had a wedge-like section, thus suggesting a curvature of the stem. A cluster of solitary rugose corals on the base of a limestone bed includes at least two geniculated specimens in life position, the calice raised above the base of the bed. This is more likely to be due to burial in situ than a current accumulation. Ostiocavichnus Bohatý et al. is not an ichnotaxon, but a palaeopathology identified as a swollen crinoid pluricolumnal; broadly analogous structures are identified in fossil decapod crustaceans.

Aim. The purpose of this study was to evaluate the efficacy of Er:YAG laser used for treating hard dental tissue in patients with epidermolysis bullosa (EB).Methods. We report two cases of EB in which an Er:YAG laser was used for conservative treatments. In the first case, the Er:YAG laser (2,940 μm, 265 mJ, 25 Hz) was used to treat caries on a deciduous maxillary canine in an 8-year-old male patient affected by dystrophic EB. In the second case, we treated a 26-year-old female patient, affected by junctional EB, with generalized enamel hypoplasia, and an Er:YAG laser (2,940 μm, 265 mJ, 25 Hz) was used to remove the damaged enamel on maxillary incisors.Results. The use of the Er:YAG laser, with the appropriate energy, was effective in the selective removal of carious tissue and enamel hypoplasia. During dental treatment with the Er:YAG laser, patients required only a few interruptions due to the absence of pain, vibration, and noise.Conclusions. Laser treatment of hard dental tissues is a valuable choice for patients affected by EB since it is less invasive compared to conventional treatment, resulting in improved patient compliance.
