The objective of the research was to substantiate the effective method of treating minor dentition defects in the lateral and frontal areas considering anatomic features, functionality and aesthetic appearance of the prosthesis.          Materials and methods. A new approach to the problem of treating minor dentition defects with the use of zirconium oxide ceramic resin-bonded prostheses was proposed. The method of its manufacturing was described and the indications to the application were clearly explained. The comparative analysis with similar prostheses was conducted and the advantages of the proposed prosthesis were proved. Ceramic resin-bonded prosthesis allowed us to restore the dentition integrity in the presence of small bounded edentulous spaces in the lateral region and to provide high aesthetic qualities and bio-inertness of the prosthesis with maximum approximation to the physiological characteristics of natural teeth.     Results. Thirty-eight patients with small bounded edentulous space in the lateral region were treated with the use of zirconium oxide resin-bonded prosthesis for 18 months. The obtained results of prosthetic treatment indicated that the proposed prosthesis provided an opportunity to restore the aesthetic appearance and integrity of the dentition, to prevent the occurrence of the deformations and to ensure the functionality of the dento-facial system.          Conclusions. The framework made of zirconium oxide allowed us to significantly reduce the depth of hard dental tissue preparation resulting in a great aesthetic appearance thereby providing an opportunity to significantly expand the indications for use. The remote results of treatment indicated the absence of marginal coloration at the margin of indirect restoration and hard dental tissues, namely the marginal ridge, ensuring good aesthetics and functional integrity of the restorative construction.

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.

Summary The laser coagulation at the apical part of the root canal after vital extirpation is a proper method of preventing complications such as pain, bleeding, remaining vital pulp. The aim of the present survey is to register the thermal changes that occur on the tooth surfaces during laser treatment of the root canal after vital extirpation. An in vitro study of 30 extracted teeth has been conducted. The teeth have been prepared with ProTaper nickel-titanium machine tools and wiped dry. During the course of laser treatment of root canals with a diode laser DenLase temperatures, changes of the surface of the hard dental tissues have been recorded with infrared camera FLIR T330. The captured thermal images have been processed with software product Flir Reporter Pro 9. In conclusion, temperature changes in hard dental tissues at diode laser treatment of the root canal are biocompatible.

Clinical and instrumental diagnostics, including electromyographic (EMG) and axiographic (EA) study of 24 patients to improve the efficiency of planning and predicting the results of their dental treatment was carried out. Correlation links were studied both within EMG and EA studies, and between them. There were no significant correlations between the parameters of EMG and EA of the methods of investigation. Therefore, for full dental rehabilitation ofpatients with tooth wear in the diagnosis and monitoring of the stages and results of treatment, it is necessary to carry out both methods, since they do not exclude each other, but supplement

Relevance. Skeletal malocclusion stands at the head of all oral diseases and is encountered in 32-35% of children and adolescents in Russia [7;12;15]. The number of malocclusions has increase due to various reasons, one of which is early extraction of deciduous carious teeth resulting in impaired vertical dimension and occlusion of teeth [1;14]. Diagnosis with due regard to caries resistance degree and planning of respective operative and orthodontic treatment are indispensable in children with skeletal malocclusion. Purpose – to increase effectiveness of functional treatment of malocclusion in children with various degree of caries resistance.Materials and methods. There were examined 108 patients aged between 6 and 16 with Class I malocclusion according to Angle, abnormal arch-to-arch relationship and tooth position and various degree of caries resistance. 4 groups were formed: high, sufficient mean, decreased mean and low caries resistance of dental enamel. Intensity of carious process was detected in all patients before and after orthodontic treatment. The effectiveness of reminerlization administered by removable orthodontic appliances was evaluated by electrometrical testing of hard dental tissue. Surface EMG was used to assess normalization of tone of maxillofacial muscles in children by average amplitude of biopotentials of superficial masseter and temporalis muscles.Results. Сhanges in caries intensity in children after treatment with removable orthodontic aligners indicate the necessity for remineralization of hard dental tissues during orthodontic treatment and it is confirmed by decrease of electroconductivity of enamel in children with sufficient mean, decreased mean and low degree of dental enamel caries resistance. Increase of biopotential mean amplitude during «total mastication» for masseter and temporal muscles confirms effectiveness of preformed elastic positioner along with myodynamic exercises.Conclusions. The conducted study proves the necessity of comprehensive approach with procedures  increasing the degree of caries resistance of hard dental tissues during orthodontic treatment of skeletal malocclusion in children.

New Research

Currently, the development of the use of biomaterials and their application in medicine is causing rapid changes in the fields of regenerative dentistry. Each year, new research studies allow for the discovery of additional possibilities of dental tissue restoration. The structure and functions of teeth are complex. They consist of several diverse tissues that need to act together to ensure the tooth’s function and durability. The integrity of a tooth’s enamel, dentin, cementum, and pulp tissue allows for successful mastication. Biomaterials that are needed in dentistry must withstand excessive loading forces, be biocompatible with the hosts’ tissues, and stable in the oral cavity environment. Moreover, each tooth’s tissue, as well as aesthetic qualities in most cases, should closely resemble the natural dental tissues. This is why tissue regeneration in dentistry is such a challenge. This scientific research focuses on paediatric dentistry, its classification of caries, and the use of biomaterials in rebuilding hard dental tissues. There are several methods described in the study, including classical conservative methods such as caries infiltration or stainless-steel crowns. Several clinical cases are present, allowing a reader to better understand the described methods. Although the biomaterials mentioned in this work are artificial, there is currently ongoing research regarding clinical stem cell applications, which have a high potential for becoming one of the most common techniques of lost dental-tissue regeneration in the near future. The current state of stem cell development is mentioned, as well as the various methods of its possible application in dentistry.

Definition Of

Since the early days of gene therapy, both the scientific community and the public have perceived the ethical challenges intrinsic to this discipline. First, the technology exploited by gene therapy is still experimental and burdened by important safety issues. Second, in several instances gene therapy aims at stably modifying the genetic characteristics of individuals. Third, the same modifications could in principle be applied also to embryos, foetuses or germ cells. Finally, while gene therapy applications are generally accepted for therapeutic purposes, the same gene transfer technologies could also be exploited to improve the aesthetic appearance, or the physical and intellectual performance of people. The definition of suitable guidelines for a controlled, ethically accepted translation of gene therapy to the clinics remains a major challenge for the near future.
