Glass Ionomer Modified with Bacterial Cellulose Nanocrystals. An In Vitro Analysis Assessing Shear Bond Strength and Microleakage Scores in Deciduous Dentition

The aim of this study was to evaluate the shear bond strength (SBS) and microleakage of bacterial cellulose nanocrystals (BCNCs) incorporated into conventional glass ionomer cement (CGIC) when bonded to deciduous dentin. Sixty primary first and second molars with class I cavitated dentinal lesions were preserved and randomly allocated into two groups based on the technique used for caries removal. Group 1 utilized the conventional approach for caries removal, while Group 2 used Carie Care™ for caries removal. Each of these groups was further divided into two subgroups based on the type of restoration received. Microleakage and failure mode assessments were performed using a stereomicroscope, while SBS testing was conducted using a universal testing machine. The SBS and microleakage scores were analyzed using one-way analysis of variance (ANOVA) and Tukey post hoc test with a significance level of p=0.05. Specimens from Group 1A (conventional approach+CGIC) presented the highest scores of marginal leakage, while Group 1B (conventional approach+BCNCs-modified CGIC) demonstrated the lowest values of microleakage. Additionally, samples from Group 2B (Carie Care™+BCNCs-modified CGIC) revealed the highest bond integrity scores. The incorporation of BCNCs into CGIC had a positive impact on both shear bond strength and marginal leakage when bonded to the dentin substrate. This modification improved the performance of the glass ionomer cement, enhancing its applicability in dental restorations.

Adhesive restorations in primary dentition: A retrospective analysis of survival rate and associated factors.

Several clinical and individual factors may play a role in the survival rate of dental restorations, such as characteristics related to the child's age and oral hygiene, and factors associated with the tooth, such as the type of material and number of surfaces to be restored. To analyse the survival rate of adhesive restorations on primary teeth and factors associated with restoration survival. The study included dental records of children aged 3-12 years having received adhesive restorations on primary teeth at a Brazilian dental school between 2009 and 2019. A Kaplan-Meier survival curve was used to plot survival rates using the log-rank test. A multivariate Cox regression model was run to identify individual and dental factors associated with restoration failure. The sample comprised 269 restored teeth in 111 children. Survival curves were similar for all materials (p = .20) and types of isolation (p = .05). The annual failure rate was 3.60% for glass ionomer cement, 1.23% for resin-modified glass ionomer cement and 0.40% for composite resin. The following variables were associated with more failures: Class II restoration compared with Class I (HR = 1.96; 95%CI: 1.28-2.99, p < .001), proportion of decayed teeth (HR = 11.89; 95%CI: 2.80-50.57, p < .001) and child's age (HR = 1.17; 95%CI: 1.06-1.29, p < .001). The different materials and types of isolation had similar survival rates. Children with more decayed teeth have an increased risk of restoration failure.

Comparing Military and Civilian Dentists' Treatment Planning Decisions: A Pilot Study.

Clinical decision-making varies among dentists. However, the literature is limited and narrow in scope regarding the variation between public and private sector dentists. Because both types of dentists' decisions can directly influence military dental readiness, it is important to understand the potential differences in diagnosis, treatment planning, and the delivery of care. The purpose of this pilot study was to compare treatment planning recommendations between civilian and military providers. Patient-level data from the 2018 Recruit Surveillance, a stratified, cross-sectional study of 1,208 randomly selected U.S. Air Force recruits, were used to evaluate treatment planning outcomes for the 2 provider groups (2 civilians; seven military providers). Treatment planning outcomes included type of noninvasive, operative, and oral surgery treatment recommended, temporomandibular disorder referrals, and orthodontic referrals. Patient demographic variables included age, gender, education, race/ethnicity, and military component ("status"). Data were examined both at the tooth level and patient level for statistical significance. Multivariate analyses were performed with statistically significant variables included in each final model for patient-level data. Data were analyzed with logistic regression and Poisson regression (alpha = 0.05). Bivariate logistic regression analyses were performed for tooth-level data. Significant differences were found between military and civilian dentists' treatment planning decisions (P < .05) for both patient-level and tooth-level data. Adjusted for significant bivariate predictors of patient demographics at the patient level, civilian dentists were more likely to refer patients for orthodontic treatment, prescribe remineralization for sound tooth surfaces, incipient caries, and carious teeth, and prescribe direct restorations for teeth with 3 to 5 carious surfaces instead of single crowns compared to military dentists. Additionally, civilian dentists were less likely to prescribe sealants for sound tooth surfaces or carious teeth. No statistically significant difference in treatment planning outcomes was observed between civilian and military dentists for sealants for incipient caries, single crowns, or extraction of third molars. At the tooth level, civilian dentists were more likely to prescribe remineralization for sound tooth surfaces, remineralization instead of sealants for carious surfaces, and extraction of third molars. No statistically significant differences were noted between civilian and military providers for recommending sealant or remineralization for teeth with incipient caries or prescribing a single crown versus placing a direct restoration on posterior teeth with 3 to 5 carious surfaces. Significant differences in treatment planning outcomes between civilian and military providers exist. Civilian providers are more likely to refer patients for orthodontic treatment and prescribe remineralization, direct restorations instead of single crowns, and third molar extractions, while military providers are more likely to prescribe sealants for sound tooth surfaces or carious teeth. Therefore, comparisons of treatment planning outcomes between civilian and military providers warrant further research.

Evolution of the Guided Direct Composite Resin Technique in Restorative Dentistry: A Systematic Review.

This systematic review aims to understand the limitations and benefits of the guided direct restorative technique, to optimize the final outcomes, considering the evolution from analog to digital, including planning, the diversification of guides, and the different resins employed. A search was conducted in the electronic databases PubMed, Cochrane, and through manual searches, initiated in May 2023 and updated in April 2024. The following search strategy was used: ((injectable composite resin) OR (direct pressed composite)) OR (3D-guided), utilizing the PICO framework. Initially, 739 articles were retrieved. After applying inclusion and exclusion criteria, 33 studies were considered suitable for data extraction, including 12 in vitro studies and 21 case reports or technique descriptions. The articles focused on comparisons of techniques, flowable, heated, and conventional resins, as well as various technique reports with variations in guides, materials, and planning, potentially aiding clinicians in more effective and safer execution of this restorative technique. The utilization of digital workflows presents greater solutions to the challenges of the guided direct restorative technique. Understanding the properties of the resins used is crucial for the results and should be chosen according to the patient's needs. A guided direct restorative procedure can deliver previously planned dental treatment based on individualized planning. This method ensures greater reproducibility in aesthetics and occlusion, resulting in superior quality work for the patient.

Reallocation of the magnificent catshark Proscyllium magnificum Last & Vongpanich, 2004 to the genus Ctenacis Compagno, 1973 (Carcharhiniformes: Proscylliidae).

The magnificent catshark Proscyllium magnificum was described in 2004 based off five specimens collected in the Andaman Sea off Myanmar. It was originally allocated to the genus Proscyllium, but recent molecular analyses suggested it was more closely related to the harlequin catshark Ctenacis fehlmanni from the western Indian Ocean. This study incorporated meristics and external and internal morphology, together with molecular data to reclassify the magnificent catshark as Ctenacis magnificum and provides revised diagnoses for the genera Ctenacis and Proscyllium. Ctenacis consists of two allopatric Indian Ocean species, while Proscyllium is monotypic genus confined to the northwest Pacific. The revised Ctenacis can be distinguished from Proscyllium in having a broader and longer head (head length 21%-23% vs. 16%-18% of total length), distance between pectoral and pelvic bases shorter than head length (vs. greater than head length), more teeth (upper jaw with 80-86 vs. 46-62 tooth files), and a complex colour pattern of dark reddish-brown blotches and saddles (vs. colour pattern of small black spots). A revised key to the genera of proscylliids and species of Ctenacis is provided.

Nonlinear Finite Element Analysis of Bone–Implant Contact in Three Short Dental Implant Models with Varying Osseointegration Percentages

Objectives: Dental implants have become a cornerstone of restorative dentistry, providing a long-lasting method for tooth replacement. The degree of osseointegration has a significant effect on biomechanical stability at the bone–implant contact (BIC), determining the continued efficacy of these implants. However, the exact consequences of changing osseointegration levels on different implant designs, especially in bones with variable densities, are not well known. Methods: This study used 3D finite element analysis (FEA) to look at the biomechanical performance of three short dental implants: BioMet 3iT3, Straumann® Standard Plus Short-Regular Neck (SPS-RN), and Straumann® Standard Plus Short-Wide Neck (SPS-WN). This paper tested the implants at four stages of osseointegration: 25%, 50%, 75%, and 100% in both high-density (bone type III) and low-density (bone type IV) cancellous bone. It also created and examined realistic CAD models under static occlusal loading conditions to assess stress distribution and major strains at the bone–implant contact. Results: The study discovered that as osseointegration increases, von Mises stress and principal strains go down significantly for all implant types. The SPS-WN implant had the lowest strain values, especially for bone with low density. These reductions demonstrate increased mechanical stability as the bone–implant interface becomes more capable of dispersing mechanical stresses, minimizing the potential for localized deformation and bone resorption. Conclusions: The results highlight the importance of achieving optimum osseointegration to reduce mechanical stress and increase the lifespan of dental implants. The SPS-WN type implant performed better in biomechanical tests than the others, especially when bone conditions were not ideal. This makes it a great choice for clinical applications that need long-term implant success.

A New Era of Tooth Preparation and Gingitage Retraction Technique: A Case Report

The demand for procedures intended to improve dental aesthetics has increased recently. Preserving the teeth and surrounding soft structures to the greatest extent possible is preferred in this situation by both patients and dentists. When using fixed prostheses, maintaining the stability and health of soft tissues is a constant struggle. Bone tissue health and soft tissue health are directly correlated. The long-term efficacy of prosthetic therapy thus depends on preserving tissue health and being free of mucositis. This case report describes the successful application of the gingitage technique in a patient requiring aesthetic enhancement of the gingival margins surrounding dental restorations. The patient presented with uneven gingival contours and mild inflammation around subgingival margins of existing restorations, compromising both function and aesthetics. Results demonstrated significant improvements in gingival health, a more balanced gingival margin, and an enhanced aesthetic outcome. Follow-up assessments revealed stable gingival contours and an overall increase in patient satisfaction. This case report underscores the effectiveness of the gingitage technique as a minimally invasive solution for enhancing soft tissue aesthetics and supporting the longevity of dental restorations.

Effect of ionizing radiation on the shear bond strength of two different adhesive systems in primary teeth. in-vitro study

BackgroundRadiotherapy is a treatment modality used for head and neck cancer patients. It has a negative influence on bonding strength of adhesives. Little information is available about the effect of radiotherapy on bonding strength of adhesives in primary teeth. Therefore, this in vitro study aimed to detect the best adhesive system and ideal time to apply restorations in primary irradiated teeth regarding adhesive shear bond strength.MethodsDentin samples from primary teeth were randomly assigned to four groups based on restoration application time and radiation exposure, (G1: control, G2: preradiation, G3: 24 h postradiation, and G4: 6 months postradiation) with 20 samples per group. These groups were further divided into 2 subgroups according to the adhesive system used, with 10 samples per subgroup. (1) 3M™ Single Bond Universal Adhesive (SB), (2) 3M AdperSingle Bond 2 (AS). Samples were exposed to gamma radiation from a cobalt-60 machine. One shot of 60 Gy of radiation was delivered. Then samples were subjected to a shear bond strength test. The load was applied until failure and the maximum load was recorded. Numerical data are presented as mean and standard deviation values, then distributed according to Shapiro–Wilk test or Levene's test and analyzed via two-way ANOVA. The significance level was set at p < 0.05 for all tests. Statistical analysis was performed with R statistical analysis software version 4.4.1 for Windows (Team RC, R: A language and environment for statistical computing. R foundation for statistical computing, 2023).ResultsCompared with the AS subgroup, the SB subgroup presented significantly greater values (p < 0.001). For SB, there was no significant difference among the G1 and G4 groups (p > 0.001). However, there was a significant difference between G1, G2, and G3 (p < 0.001, P = 0.025, P = 0.265 ns respectively), and G3 presented the lowest values. For AS, there was no significant difference between groups G1 and G4 (p = < 0.001). Compared with the other groups, G3 presented a significant difference (p = 0.265 ns) and the lowest results.ConclusionRestorations performed 24 h after radiation had lower bond strength than those performed six months after radiation. Regardless of the adhesive system used, SB performed better than AS in terms of the shear bond strength.

Evaluation of optical and mechanical properties of crown materials produced by 3D printing.

The various advantages of crown materials produced using three-dimensional (3D) printers have increased their use in restorative and prosthetic dentistry in recent years. Accordingly, their optical and mechanical properties have become more important. To evaluate the mechanical, surface and optical properties of crown materials produced with 3D printing and computer-aided design (CAD)/computer-aided manufacturing (CAM), which has recently been used frequently in the clinic. The 3-point bending test was used to evaluate the mechanical properties of 2 different crown materials produced with 3D printing (Permanent Crown and VarseoSmile Crown Plus) and a crown material produced using CAD/CAM (Vita Enamic). After the initial color and surface roughness measurements were made, the specimens were immersed in 4 different solutions. The most translucent material was VarseoSmile Crown Plus (p < 0.05). In all specimens, coffee caused the most discoloration (p < 0.05). The effects of the solutions on the roughness were mostly observed in Permanent Crown specimens (p < 0.05). Vita Enamic showed the highest statistically significant values in terms of flexural strength (p < 0.05). The stereolithographic technique among the materials produced by 3D printing can be recommended for use in restorations due to its higher flexural strength.

Beyond Traditional Fillings: Why Bulk-Fill Composites Are Changing the Game

This review examines the impact of bulk-fill composites in restorative dentistry, highlighting their advantages over traditional resin-based materials. Conventional composites often require multiple incremental placements, increasing technique sensitivity and the risk of restoration failure. Bulk-fill composites allow for placement in single layers of 4-6mm, reducing chairside time and procedural complexity. The review discusses innovations in formulation, including enhanced translucency and modifications in photoinitiators that support effective polymerization. Key properties such as microhardness, degree of conversion, depth of cure, and polymerization shrinkage are evaluated, showing that high-viscosity bulk fills can achieve hardness comparable to conventional composites. Various commercially available products are assessed for their clinical performance. The review ultimately emphasizes the growing acceptance of bulk-fill composites as reliable alternatives, advocating for continued research to enhance clinician confidence in their application and effectiveness in deep cavity restorations. Keywords: Bulk fill composites, posterior composites, incremental composite placement, tooth colored restoratives, polymerisation shrinkage, degree of conversion, depth of cure

Projeto de extensão: resgatando sorrisos

The article addresses restorative and aesthetic dentistry, highlighting the importance of adhesion of materials to mineralized dental tissues. The philosophy of minimally invasive restorative treatment is based on principles of prevention and maximum preservation, with minimal intervention in dental structures. Dental aesthetics are subjective, influenced by several factors, and despite advances in aesthetic materials, the need for clinical evaluations on the behavior of composite resin restorations is increasing. In the Brazilian context, where the provision of government dental treatment is limited, perceived need becomes an important predictor of the use of dental services. There is a significant demand for restorative dentistry procedures, often performed by undergraduate and postgraduate students. The article highlights the creation of an Orthodontics Extension Project to deal with repressed demand, although new activities are necessary. It is concluded that initiatives such as extension projects are essential to mitigate the lack of care for the population and prepare academics for clinical practices in restorative dentistry.

Rehabilitation of a Severe Anterior Ridge Defect with a Fixed-Removable Prosthesis

Significant anterior ridge abnormalities might be difficult to restore with prosthesis. To attain good speech and aesthetics necessitate not only the restoration of the missing teeth but also the closure of the problematic region. One recommended treatment option for individuals with substantial ridge abnormalities is the Andrews bridge which is a fixed-removable prosthesis. The prosthesis correctly replaces the missing teeth and corrects the ridge defect area and restore speech and appearance. A 35-year-old female patient reported with the principal complaint of spacing in her lower front teeth and difficulty in phonetics and poor appearance. On clinical examination spacing was seen in the maxillary central incisors along with pro-clination and 31,32,33,41,42,43 teeth were missing and the edentulous defect area was coming under Seibert's Class III category. Rehabilitation of such defect with an Andrews bridge described in this case report, which used natural teeth as abutments for its permanent component and a detachable superstructure.

The search for an aesthetic standard is increasingly frequent and restoring a harmonious smile represents a real challenge for restorative dentistry. Composite resins are aesthetic and adhesive materials that have received special attention for ensuring predictable and lasting results with minimal tooth sacrifice. The technique of making direct veneers is simple, but requires discretion and attention from its indication to the final stages of its execution. The procedure has high success rates and predictable results with desirable longevity for anterior teeth. The objective of this study was to present a clinical case of diastema closure with direct composite resin veneers on anterior teeth and maxillary first premolars, with the aid of diagnostic wax-up for better accuracy of work on anterior teeth. It is concluded that the application of the direct restorative technique allowed a fast, low, cost and less invasive treatment. Providing a satisfactory result, raising self-esteem and allowing a restoration of the patient's facial aesthetics.

Survival and Complication Rates of Polymer-Infiltrated Ceramic-Network Single- Tooth Restorations with an Observation Period of up to Three Years.

This study evaluated the clinical performance of a polymer-infiltrated ceramic-network (PICN) material for up to 3 years. Patients (N=286) received 581 indirect restorations as crowns (417), overlays (131), and inlays/veneers (33) fabricated using the PICN (VITA Enamic) by CAD/CAM procedures using intraoral scanning (Cerec Omnicam) and milling systems (Cerec MC XL). The restorations were evaluated annually and in case of complications. Data were analyzed using Kaplan-Meier estimate. Complications were classified as biological or technical failures. Until final recall (mean observation period: 18.3 months) with a dropout rate of 4.8%, 3 biological and 10 technical complications were observed. The overall success rate of the placed restorations was 97.7%. Biological complications included pulpitis and pulp necrosis. Technical complications were debonding (n=7) and fracture (n=3). PICN materials can be used as an alternative to lithium-disilicate or zirconium dioxide for single tooth reconstructions, providing that early failures included debonding and fractures.

Validity and Reliability According to the Type of Examiners in the Process of Calibrating Dental Caries Experience Using the DMFT Index.

The process of examiner calibration is an essential step in all epidemiological research, as it aims to ensure uniform interpretation, understanding, and application of the instrument to be used. This ensures that the data collected will be valid and reliable. This study aimed to determine the differences in concordance in dental caries calibration across three dental specialties. The population consisted of 45 dentists, divided into three groups: 15 general dentists working in the public sector, 15 dentists specializing in Dental Public Health, and 15 dentists specializing in Restorative and Aesthetic Dentistry. The calibration process was carried out in three stages: theory, calibration using photographs, and calibration on natural teeth, performed by the gold standard. In the first validity process, a statistical difference was only found between the Kappa values of the inter-examiner calibration process using photographs. For the evaluation of teeth, in the second validity process, 33.33% (n = 15) of the participants achieved "almost perfect agreement." Finally, only 75.56% (n = 34) of the examiners were considered for the reliability report; of this group, 52.94% (n = 18) were in "almost perfect agreement," and 35.29% (n = 12) were in "substantial agreement." The validity and reliability of the dental caries experience calibration process did not present significant statistical differences between general dentists in the public sector, dentists specializing in Dental Public Health, and dentists specializing in Restorative and Aesthetic Dentistry.

Human biomonitoring of essential and toxic trace elements (heavy metals and metalloids) in urine of children, teenagers, and young adults from a Central European Cohort in the Czech Republic.

Exposure to toxic trace elements, which include metals and metalloids, can induce adverse health effects, including life-threatening diseases. Conversely, essential trace elements are vital for bodily functions, yet their excessive (or inadequate) intake may pose health risks. Therefore, identifying levels and determinants of exposure to trace elements is crucial for safeguarding human health. The present study analyzed urinary concentrations of 14 trace elements (arsenic, cadmium, cobalt, chromium, copper, mercury, manganese, molybdenum, nickel, lead, antimony, selenium, thallium, and zinc) and their exposure determinants in 711 individuals, spanningfrom children to young adults from a Central European population from the Czech Republic. Multivariate linear regression and non-parametric Kruskal-Wallis ANOVA were used to investigate exposure determinants. Estimates of 95th percentile concentrations and confidence intervals were carried out to establish reference values(RV95). The study also assessed the percentage of population exceeding health-based guidance values (GVs) to gauge health risks. Young adults showed elevated toxic element concentrations, whereas children exhibited higher concentrations of essential elements. Mercury concentrations were associated with both dental amalgam filling count and seafood intake; arsenic concentrations were associated with seafood, rice, and mushroom consumption. Mushroom consumption also influenced lead concentrations. Sex differences were found for cadmium, zinc, nickel, and cobalt. Between 17.9% and 25% of the participants exceeded recommended GV for arsenic, while 2.4% to 2.8% exceeded GV for cadmium. Only one participant exceeded the GV for mercury, and none exceeded GVs for chromium and thallium. Essential trace elements' GVs were surpassed by 38% to 68.5% participants for zinc, 1.3% to 1.8% for molybdenum, and 0.2% to 0.3% for selenium. The present study examines trace element exposure in a Central European population from the Czech Republic, unveiling elevated exposure levels of toxic elements in young adults and essential elements in children. It elucidates key determinants of trace element exposure, including dietary and lifestyle indicators as well as dental amalgam fillings. Additionally, the study establishes novel reference values and acomparison with established health-based human biomonitoring guidance values, which are crucial for public health decision-making. This comprehensive biomonitoring study provides essential data to inform public health policies and interventions.

Buonocore Memorial Lecture 2023: Longevity of Dental Restorations or Longevity of Teeth: What Matters?

This paper aims to raise a discussion from the perspective of maintaining long-term oral health, posing a critical question: What holds greater significance for maintaining oral health, the longevity of restorations or teeth? This question explores the aspects that truly matter in ensuring sustained oral health throughout an individual's life. Restoration longevity is well-researched, and evidence shows several risk factors influencing longevity. The dentist's decision-making factor may be of utmost importance, and further studies are needed to investigate its relevance. The critical risk factors for restoration longevity are active pathology (high caries risk), less prominent parafunction, and extensive defects such as endodontic treatment. However, tooth longevity and the main risk factors for tooth loss are not well-researched. The evidence shows dental caries, and its sequelae, are the principal reasons for tooth loss. Patient-related risk factors, especially those associated with lifestyle and health choices, play a major role in the longevity of restorations and, more importantly, tooth longevity. To provide personalized dental care with maximum patient benefit, clinicians should identify and record potential risk factors, promoting a healthy lifestyle to ensure tooth and dentition longevity. Moreover, the evidence suggests that decision-making frameworks based on minimal intervention principles offer the best standard for clinical practice, promoting a longstanding healthy oral environment.

Evaluation of Shear Bond Strength of Universal Adhesives to Dentin: in Vitro Study

Aim: Universal adhesives are widely used in restorative dentistry. The aim of this study was to evaluate the shear bond strength (SBS) of universal adhesives to dentin in different application modes. Materials and Methods: The study utilized seven universal adhesives and one total-etch adhesive. The sixty-four extracted intact human molars used in the study were embedded in acrylic blocks to the enamel-cement junction. The occlusal surface was removed to expose the dentin surface. After applying self-etch and total-etch adhesives to the dentin, flowable composite (Clearfil Majesty Flow, Kuraray) was placed in a transparent mold (2.38 mm diameter and 2 mm height) and polymerized. After thermal aging (1000 cycles), a SBS test has been carried out on a universal testing machine. The fracture types formed on the surface of the teeth were examined under a microscope. Data were analyzed by two-way analysis of variance (ANOVA) test (p&lt;0.05). Results: SBS values of universal adhesives on dentin showed statistically significant differences according to adhesive and application mode (p&lt;0.05). Total-etch application produced statistically higher SBS than self-etch application (p&lt;0.05). The two-step universal adhesive (G2 Bond Universal) had the highest SBS in both the self-etch and total-etch application modes (p&lt;0.05). When the bond surfaces of the universal adhesives were examined, fractures occurred most frequently in the adhesive type. Conclusion: The use of universal adhesives in the total-etch mode results in greater bond strength to dentin tissue. Universal adhesive type influences bond strength.

The rapid development of nanotechnology in medicine and dentistry has led to an exponential increase in the scope of research in this area. Aspects of nanotechnology that have already brought benefits include advanced drug delivery platforms, molecular imaging, and the development of treatment materials in dental practice. The aim of the research. To investigate the current possibilities of using nanotechnology in dentistry for diagnosis and treatment. Materials and methods of the research. The materials were used scientific publications by authors conducting their scientific and practical research in the field of dentistry and nanotechnology. The search was conducted in the scientometric databases PubMed, Scopus, Web of Science, Google Scholar using the terms “nanoparticles”, “oral cavity”, “nanomaterials”, “nanodentistry”, “diseases”, “biomaterials”, “treatment”, “diagnostics”. The research was conducted using such scientific methods as theoretical generalization and grouping, formalization, analysis, synthesis, and generalization of the results. The search resulted in the selection of publications for the period 2019-2024 that studied nanotechnology and its application in dental practice in diagnosis and treatment and will be discussed in this review. Results. The article shows a unique feature of nanotechnology, which is that the properties of a material at the nanoscale can differ from those at the macro level. This can be explained by two reasons: first, nanomaterials have a large surface area to volume ratio, which causes their high reactivity and, accordingly, affects their mechanical and electrical properties. Secondly, at the nanoscale, quantum effects dominate the material's behavior, giving rise to interesting observations of its electromagnetic and optical properties. Knowing the beneficial aspects of nanomedicine, scientists are trying to use nanotechnology to diagnose, treat and prevent dental diseases. Nanotechnology is used for sensitive medical procedures. They also demonstrate successful and useful applications for precise pain management, tooth restoration, and reduction of tooth hypersensitivity. Nanomaterials can plug open dentinal tubules, improving patient comfort and overall oral health. Orthodontic therapy has also been revolutionized by nanomaterials with shape memory properties, which enables faster and more efficient tooth movement. The development of revolutionary products and therapeutic alternatives is supported by ongoing research efforts, enabling the creation of dental implants, fillings and prostheses that closely mimic the characteristics of natural teeth. Nano-delivery systems are being developed to deliver drugs precisely into the oral cavity, providing optimal therapeutic outcomes with minimal side effects. This review highlights the multifaceted aspects of nanomedicine and how nanotechnology is proving to be useful in the diagnosis and treatment of dental diseases. The integration of nanotechnology into dentistry represents a groundbreaking evolution that goes beyond conventional oral care methods, allowing for the development of innovative diagnostic methods and improved oral health. Prospects for further research. Nanotechnology has revolutionized dentistry by changing the way oral care is conceptualized, delivered, and maintained. To develop effective methods for the diagnosis and treatment of dental diseases, it is necessary to continue research on the optimization of the mechanical properties and cytotoxicity of dental composite materials based on nanotechnology.
