Neither the occlusal nor the nociceptive trigeminal inhibition splint showed any significant influence on the examined muscles. Different scientific methods should be considered in clinical applications that require either direct influence on the muscles' bioelectrical activity or a quantitative measurement of the treatment quality.

On the basis of selected cases, evaluation of the usefulness of muscular exercises in rehabilitation of patients stricken by a dysfunction of the motor system of the chewing organ was accomplished. The assessment of the electric function of chewing muscles together with the registration of mandibular movements with the axiographic Zebris JMA apparatus was made, both before and after muscular therapy. The examination has shown that regardless of micro or macro-traumatic cause, the set of muscular exercises appropriately selected and dutifully carried out is able to restore full condition of the motor system of the bone-dental structure effectively.

The Purpose of the Paper. Qualitative and quantitative analysis of selected parameters of mandible movements, electronically registered in patients with temporomandibular joint dysfunction and healthy ones. Material. Function test of the mandible movements was conducted in 175 patients. Gender distribution was 143 women and 32 men, aged 9 to 84. Methods. The studied population, after accurate clinical examination, was divided into age groups with the range of five years. All the patients had Zebris JMA computerized facebow examination done, according to the generally accepted principles and procedures. Results. Mean values of mouth opening calculated to 45.6 mm in healthy group and 37.6 mm in TMJ dysfunction group. Mean length of condylar path amounted to 39 ± 7% of the maximum value of mouth opening in the group of healthy people, 44 ± 11% in the case of muscle-based disorders, and 35 ± 11% with joint-based. The mean value of the condylar path inclination oscillated in the range of 25° to 45°. Conclusions. The ratio of length of the condylar path to the size of mouth opening may be a significant value characterising the type and degree of intensification of the TMJ dysfunctions.

Photogrammetry is a science and technology which allows quantitative traits to be determined, i.e. the reproduction of object shapes, sizes and positions on the basis of their photographs. Images can be recorded in a wide range of wavelengths of electromagnetic radiation. The most common is the visible range, but near-and mediuminfrared, thermal infrared, microwaves and X-rays are also used. The importance of photogrammetry has increased with the development of computer software. Digital image processing and real-time measurement have allowed the automation of many complex manufacturing processes. Photogrammetry has been widely used in many areas, especially in geodesy and cartography. In medicine, this method is used for measuring the widely understood human body for the planning and monitoring of therapeutic treatment and its results. Digital images obtained from optical-electronic sensors combined with computer technology have the potential of objective measurement thanks to the remote nature of the data acquisition, with no contact with the measured object and with high accuracy. Photogrammetry also allows the adoption of common standards for archiving and processing patient data (Adv Clin Exp Med 2015, 24, 4, 737-741).

Introduction: A great number of hereditary diseases have been correctly diagnosed and treated recently as a result of the rapid progress and constant development of genetic research. Case report: This study presents the case of 24-year-old female patient suffering from MELAS syndrome, which is inherited in the maternal line -as are other mitochondrial diseases. This disorder was first described in 1984 by Steven G. Pavlakis et al. Our paper describes prosthetic procedures that were undertaken as treatment for the patient mentioned above, who had been referred from a hospital neurological clinic for consultation and possible treatment due to her refractory migraines. Regardless of the previously noted symptoms, the patient was examined for bruxism, and considering the positive outcome of the test, typical treatment, including a stabilization appliance was implemented. It gives significant improvement and lesser occurrence of neurological symptoms. Conclusions:The patient stays under the constant, periodic control of our department. Keywords: MELAS syndrome; occlusal splint; bruxism; doxepin; venlafaxine; surface electromyography.

Introduction: Nanotechnology has been established in dental specialities as a novel methodology for developing materials with enhanced physical properties and antimicrobial potential. In this review, we discuss the current progress, prospects, and potential future applications of functional nanoparticles contained in nanomaterials as useful strategies for refining their ability to resist occlusal forces, as well as oral biofilm management. We also provide an overview of the suggested antimicrobial mechanisms for these nanoparticles. The purpose of this study was to use an evidence-based approach to assess the possible applications of nanomaterials in various fields in contemporary and potential future dentistry. Methods:A comprehensive search of Medline (PubMed) and the ISI Web of Science database was carried out. Results: Nanomaterials have significant potential for decreasing bacterial biofilm accumulation, inhibiting the demineralization process, remineralizing dental tissues, and combating cariesrelated bacteria. However, their ability to withstand intraoral forces needs to be further improved. Conclusions:The results reviewed in this work present a bright outlook and open doors for future clinical studies that will allow admission of the therapeutic value of nanotechnology-based dental materials. Keywords: acrylic resins; graphene; nanocomposites; nanoparticles; silver. ABSTRAKT Wstęp: Nanotechnologia na dobre zagościła w poszczególnych specjalizacjach stomatologicznych jako nowatorska metodologicznie idea wdrażania materiałów o zarówno podwyższonych parametrach mechanicznych, jak i posiadających olbrzymi potencjał antymikrobiologiczny. Praca przedstawia obecny postęp, perspektywy, potencjalne przyszłe zastosowania oraz ograniczenia nanocząstek w aspekcie wytrzymałości określonych materiałów stomatologicznych oraz ich odporności na biofilm jamy ustnej. Celem niniejszego przeglądu piśmiennictwa była rzetelna analiza potencjalnych korzyści i zagrożeń wynikających z zastosowania nanocząsteczek w jamie ustnej w świetle medycyny opartej na dowodach, zarówno obecnie, jak i w niedalekiej przyszłości. Metody:Przeszukano bazy danych Medline (PubMed) i ISI Web of Science. Wyniki: Nanomateriały posiadają znaczący potencjał hamujący agregację płytki bakteryjnej, mogą przeciwdziałać procesom demineralizacji, remineralizować tkanki zębów oraz zwalczać określone typy drobnoustrojów. Jednakże ich zdolność do znoszenia dodatkowych obciążeń, a tym samym zwiększania wytrzymałości mechanicznej, nie znajduje potwierdzenia w obecnie dostępnym piśmiennictwie i wymaga dalszych badań. Również odległe skutki ich użycia, z potencjalną toksycznością włącz-nie, nakazują zachować dalece idącą ostrożność w stosowaniu.
