In the article has been presented an analysis of susceptibility of selected dental materials, made in the CAD/CAM technology. The morphology and structural properties of selected dental materials and their composites were determined by using XRPD (X-ray powder diffraction) techniques, as well as the IR (infrared) spectroscopy. Moreover, an adhesion as well as development of biofilm by oral microorganisms has been studied. It has been shown that a degree of the biofilm development on the tested dental materials depended on microorganism genus and species. Streptococcus mutans has demonstrated the best adhesion to the tested materials in comparison with Candida albicans and Lactobacillus rhamnosus. However, the sintered materials such as IPS e.max® and the polished IPS e.max® have showed the best “anti-adhesive properties” in relation to S. mutans and L. rhamnosus that have not formed the biofilm on the polished IPS e.max® sample. Furthermore, S. mutans have not formed the biofilm on both surfaces. On the contrary to S. mutans and L. rhamnosus, C. albicans has demonstrated the adhesive properties in relation to the above-mentioned surfaces. Moreover, in contrast to S. mutans and C. albicans, L. rhamnosus has not formed the biofilm on the polished IPS Empress material.
istic wear of the incisal and occlusal surfaces of the teeth, cervical lesions as well as periodontal damage and atrophy [3]. These pathological changes can be very extensive. The systemic and external symptoms of masticatory system disorders (MSD) also include headache, neck and back pain, earache, tinnitus and hearing disorders, hypertrophy of the masseter and temporal muscles (a so-called "square-shaped face"), soreness in the region of the attachment points of the masseter and temporal muscles and an increase in tension and pain in the muscles of the shoulder girdle.The symptom of temporomandibular disorder (TMD) that usually make patients seek medical help is pain, which can take the form of severe headaches, often confused with migraine headaches, and/or facial pain. In general, TMD patients are adults, but TMD can occur also in childhood [8,10]. It is generally the result of the coexistence of at least few of the factors that preThe masticatory system (MS) is the morphofunctional complex of mutually interacting tissues and organs of the mouth and facial part of the skull, forming a functional unit controlled by the central nervous system involved in the act of chewing, initial digestion, swallowing, the formation of sounds, breathing and participating in the expression of emotions. The individual components of this system interact with each other, creating a biological morphological-functional complex [1]. Dental articulation, the joints and chewing muscles are elements of the MS that are closely related both anatomically and topographically [2]. As a result of parafunctional activity, excessive and prolonged muscle tension can occur around the temporomandibular joint (TMJ), the suboccipital muscles, the cervical spine and, frequently, the shoulder girdle muscles. In addition, an overload of the TMJ is observed. The oral cavity of patients with an overloaded TMJ usually shows character- AbstractThe purpose of this work is to present a new, still experimental method of treating temporomandibular disorders (TMD) by injecting botulinum toxin Type A (TBX-A), using its effects not as a toxin but as a medication. The mechanism of TBX-A, indications and contraindications for its use, as well as possible side effects, are discussed. Temporomandibular disorders are of concern to approximately 70-80% of the population. The effect of botulinum toxin depends on blocking the release of acetylcholine from a presynaptic neuromuscular synapse and, in the autonomous system, blocking its release from post-ganglionic cholinergic neurons. In cases of long-term TMJ disorders, muscle activity increases and spastic contractions may even appear. TBX-A offers an opportunity for a normal social and family life for many patients suffering from masticatory system disorders (MSD), who have been isolated from the environment by pain. The study is based on a review of the literature and the authors' own experiences during several attempts to treat patients by this method. TBX-A is a safe medicine when the injection is performed by a w...
The purpose of study was to analyze the participants’ opinions concerning the effectiveness of 6 denture adhesives (DA).The study group included 60 participants. Criteria for selecting the patients were as follows: reduced retention and stabilization of maxillary complete dentures and xerostomia. These features were evaluated on basis of clinical examination and standard sialometry tests (u-SFR). Retention of maxillary dentures was scored by modified Kapur index before application of DA. All participants were divided randomly into 6 groups regarding the use of the 6 DA during a 6-month period. After this time, participants completed an HRQL questionnaire.DA noticeably improved retention and stabilization of maxillary complete dentures. DA in the glue form had the best retention effectiveness in participants with xerostomia. These materials are difficult to clean from the denture base. The data are presented in tables and figures.The results of the study collected positive influence of adhesives on retention of dentures in xerostomia patients. The cleaning dentures and denture bearing tissues was difficult.DA help in the use of prostheses, but it is also necessary for the treatment of the causes and symptoms of xerostomia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
