Personalized Approach

This study proves the necessity of using new minimum intervention tooth-preserving technologies and their implementation methods in hard dental tissue pathology treatment, in particular, wedge-shaped defects within enamel. Personalized approach to choosing the treatment method for this type of pathology is updated. The study prioritizes the pathogenetic mechanisms of this process, taking into account morphofunctional changes in enamel. Changes in architectonics of tooth enamel and its elemental composition are studied and discussed. A method of delivering the medication directly into the lesion is suggested. The objective of this study was to develop a precision device for targeted delivery of medication and creation of isolated reservoirs in the wedge-shaped lesion. Materials: slices of teeth removed due to orthodontic indications. Methods: experimental, analytical, statistical, sociological, electron microscopy. The scientific basis and principles of the research concept are based on the data on microstructural transformations, changes in the elemental composition of the tooth with a wedge-shaped defect. It is proved that oxygenation increases in a wedge-shaped lesion while the amount of fluorine and carbon compounds decreases, leading to the presence of such non-specific microelements as sulfur. The results obtained are the basis for the application of a targeted and personalized algorithm for treating this pathology, using additive technologies and 3D printing

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.

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.

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.
