Root surface biomodification has been used to treat gingival recession and periodontitis. For example, to improve treatment efficacy of gingival recessions (GR), chemical preparation of the exposed root surface is advocated. The principle for this procedure is to remove the smear layer from the root surfaces, which leads to exposition of surface collagen fibers and improved healing. The aim of present article is to evaluate the importance of root surface biomodification after scaling and root planing (SRP) and a comparative review of various root conditioning agents. The review was written during the search for English-language literature in the Google Scholar and PubMed databases. 104 literary sources were identified during the literature review. After excluding publications that did not meet the inclusion search criteria, the total number of included articles has become 55. The instrumented root surface is always covered by a smear layer, containing remnants of dental calculus, contaminated root cementum, bacterial endotoxin and subgingival plaque after the scaling and root planning procedure. The root conditioning agents, described in this study, were found to be effective in the removal of the smear layer, able to produce uncovering and widening the dentin tubules, and unmasking the dentin collagen matrix. Within the limits of this study, the most frequently used conditioning agents are tetracycline, EDTA, and citric acid; among them Tetracycline HCL is the most reliable agent. [ABSTRACT FROM AUTHOR]

Periodontitis and gingivitis are complex infectious diseases, which led to damage of the tooth supporting apparatus. In general, various periodontal diseases represent a vast problem in modern dentistry with a prevalence of 20-80% in the world population.

The final goal of periodontal treatment is to achieve functional and anatomical tissue regeneration. Numerous techniques have illustrated favorable effects on anatomical and functional periodontal regeneration, but long-term results are highly variable. In addition, techniques for closure of class I-II recessions have results up to 100% with high predictability, in contrast to Miller class III-IV recessions, according to the literature. This systematic review aims to define the different techniques for closure of Miller class III-IV recessions and to identify their characteristics in different clinical situations. A study of publications in the electronic databases PubMed, Google Scholar and eLIBRARY was performed through a literature review. Articles concerning various techniques for closure of class III-IV recessions were included. A total of 100 articles were reviewed during the revision process. After analyzing the literature according to the inclusion criteria, the final number of articles had become 46. The features of the various techniques as well as long-term surgical outcomes were reviewed. Many techniques should be further investigated, due to insufficient clinical data and a few number of cases. [ABSTRACT FROM AUTHOR]

Light-curing composite restorative materials are widely used by dentists of various specialties in the esthetic restoration because of their optimal mechanical properties and predictable desired aesthetics. However, their use requires special attention to the safety of the components used. In recent decades, polymer composites have been developed with the objective of reducing cytotoxicity and shrinkage during polymerization and improving aesthetics. The biocompatibility of all polymeric materials is an issue that requires special focus on the chemical composition of biopolymers, which consist of an organic resin matrix and ceramic reinforcing filler particles bonded with a silane. The special priority in biocompatibility studies has focused mainly on the organic resin polymer matrix. And among the components of composite resins, the polymer matrix is the only unstable one, mainly because of the unbound monomers that can be released and remain as free monomers during the polymerization step. The aim of this study was to evaluate the effectiveness of preheating composite restorative materials on composite conversion and their cytotoxic properties. The use of composite restorative materials preheating in dental practice allows dentists to reduce the cytotoxicity of composite materials and improve their degree of conversion, since there is a direct relationship between increasing the conversion of the material and reducing its cytotoxicity. Preheating has a positive effect on composite, resulting in reducing their cytotoxic properties and optimizing the biocompatibility of the polymer matrix with hard tissues. The conversion of the material is improved, since there is a direct correlation between the increase in the conversion of the material and the reduction of its cytotoxicity. [ABSTRACT FROM AUTHOR]

Tooth restoration involves the use of various types of materials. In modern reality, light-curing composite materials are used for this purpose. Also, polymer cements of various types of polymerization are used to fix indirect structures in highly aesthetic areas. All dental composites are polymerized according to the free radical type. The formation of free radicals and curing occur as a result of a thermal, chemical, or photochemical reaction. Polymerization of composites never occurs at 100%; upon contact with air, the surface of the material interacts with oxygen, which leads to the termination (inhibition) of the polymerization reaction. To prevent the formation of an oxy-geninhibited layer (OIL) on the surface of the composite, chemically inert, oxygen-impermeable protective glycerol gels are used. To evaluate the feasibility and effectiveness of glycerol in preventing the oxygen-inhibited layer formation and to determine the relationship between the group of the composite and its qualitative composition during the formation of an oxygen-inhibited layer during polymerization. This study was carried out using an Infralum FT-801 IR Fourier spectrometer in KBr tablets. 135 samples of 12 various composite materials were studied; each was subjected to IR spectrometry, cured in glycerol or without glycerol. 15 specimens of Enamel plus UE composite material underwent pre-polymerization heat in a special oven (Micerium; Avegno, Italy) to 55°C before one heating cycle. The obtained results allowed us to conclude that the type of composite material does not significantly affect the process of oxygen inhibited layer formation. Regardless of the composite material group, under aerobic conditions, an incomplete conversion occurs, and an oxygen inhibited layer is formed. Anaerobic conditions do the conversion completely, which leads to the absence of oil, which was confirmed by infrared spectroscopy data. [ABSTRACT FROM AUTHOR]

The use of ultra-short (US) implants is a conservative, and more affordable method for rehabilitation of edentulous zones in severely atrophic jaws. US implants eliminate the necessity of augmentation procedures. With that in mind, a systematic review was established to assess the applications of US implants, and their reliability as an alternative of conventional implants. In this systematic review, an electronic search for English literature was carried out on the 22nd of July 2022 and ended on the 27th of July 2022, in the databases of PubMed, Google scholar, Scopus, and ResearchGate, for studies in which US implants were used. A total of 151 articles were identified by keywords. Ultimately, after applying the inclusion and exclusion criteria, 28 fulltext articles were included and analyzed in our systematic review. Chief question in this article was: When is the use of ultra-short implants more favourable, and how viable are they? Twenty-eight studies comprising 1221 implants were selected for the systematic review. US implants were mainly used in atrophic alveolar ridges, to avoid bone augmentation procedures. US implants showed a survival rate of 97.1% among all authors. US implants showed a mean periimplant bone loss of 0.38 mm over a mean period of 42 months. Placement of US implants in oneor two-stage technique had no influence on any variables. The placement of US dental implants has presented a viable option in the rehabilitation of patients with atrophic alveolar ridge, with the aim of avoiding bone augmentation procedures. However, the long-term effectiveness of US dental implants remains to be further investigated. [ABSTRACT FROM AUTHOR]

Three-dimensional digital technologies and artificial intelligence (AI) are one of the most recent and relevant advancements in the field of dentistry, including in orthodontics. These systems have enabled clinicians to increase the accuracy of diagnosis and treatment planning, to improve patient care along with reducing treatment planning time. The present study aims to explore possible applications of the artificial intelligence (AI) to examine the upper airway and to assess the reliability of the automatic evaluation of cone-beam computed tomography (CBCT). Thirty CBCTs, with the field of view 15*15, were uploaded to the Diagnocat (LLC Diagnocat, Moscow, Russia) account, and the radiologic orthodontic report of each was generated as the basis of automatic evaluation. The same CBCTs were manually evaluated by independent evaluator. 3D color visualization of upper airway, total and minimum volume, UPW, LPW, PASmin and A/N ratio were assessed. The data were collected to allow statistical analysis with Microsoft Excel software. A total of 60 reports were created for 30 CBCTs. Reliability the correspondence between the two methods was 93.3%. A positive correlation between the minimum sagittal linear dimension (MSLD) on 2-dimensional reconstructed lateral cephalograms and minimum cross-sectional area (MCSA) on the CBCTs and a negative correlation between A/N ratio and total area airway were established. The AI system can be helpful as an initial evaluation of upper airway screening CBCTs, giving appropriate credibility reports and suggesting additional diagnostic methods for more accurate evaluation if needed. The AI technology can also help improve the accuracy of diagnoses for orthodontic treatment, therefore, helping orthodontists work more efficiently. However, the AI has shortcomings in assessing adenoid hypertrophy (AH). In conclusion, the fields of artificial intelligence in orthodontic diagnostics can be useful for upper airway screening and also have great priorities. Research in the field of upper airway diagnostics using artificial intelligence requires further studies. [ABSTRACT FROM AUTHOR]

The goal of this study was the need to update the chlorhexidine adhesive protocol in the treatment of devital teeth in the presence of TIMP1 and TIMP2 in fragments of removed teeth previously endodontically treated and removed according to indications using PCR. The study was conducted on 38 human molars removed according to indications, which were divided into 2 groups: 1 group of the studied samples - 22 removed devital molars and 2 group - the control group - these are 16 third molars removed according to orthodontic indications. The removed teeth of each group were fragmented using a diamond-coated disk and air-water cooling. According to the results it was found that MMP 2 and MMP 9 are contained not only in vital, but also in devital teeth. The use of a chlorhexidine adhesive Protocol is relevant in both clinical cases but depending on the type of MMP and the state of the pulp the concentration of chlorhexidine is selected.
