CREATION OF CARIES DETECTION SYSTEM

The usage of modern technological solutions in dentistry is gaining increasingly popularity. Every year the systems are becoming more and more perfect. Of course, it will take more than one year to get the best ones and most reliable results, but you can be sure that it will completely change the way people think about receiving quality dental treatment. Identifying the problem, treatment and its quality directly depends on the human factor from both sides. This applies both to the doctor’s qualifications and his own experience, and to the patient. At the same time, doctors very often have to deal with non-standard and unique cases, complications, which in the future are accompanied by the involvement of a whole team of specialists. From the patient’s side – from X-ray to computed tomography – has a very high probability of receiving completely different diagnoses from specialists of the same sector. That is, in essence, his health depends on how accurately dentists will be able to interpret the results of examinations and formulate a treatment plan. In order to minimize the influence of the human factor, the use of artificial intelligence, which does not have the ability to miss nuances, feel fatigue and be distracted, is quite necessary.Caries, also known as tooth decay or cavities, are one of the most common oral health problems. They are caused by the buildup of plaque and bacteria on the teeth, which can lead to erosion of the enamel and dentin. Dental x-rays, also known as radiographs, are commonly used to detect caries in the early stages. However, interpreting radiographs can be challenging and prone to human error. AI-based caries detection systems can assist with the interpretation of radiographs by identifying patterns in the images that are indicative of caries. One example of an AI-based caries detection system is a machine learning algorithm will be trained to recognize patterns in radiographs that are indicative of caries. The algorithm can analyze the x-ray images and flag any areas of the tooth that have a high probability of being carious. This can help dentists identify the problem in its early stages, when it is still reversible, and provide appropriate treatment. AI-based caries detection systems can also be used to improve patient diagnosis and treatment by identifying high-risk patients, providing more accurate diagnosis, and developing personalized treatment plans.

СРАВНИТЕЛЬНАЯ ХАРАКТЕРИСТИКА ПЛОТНОСТИ ОКОЛОПУЛЬПАРНОГО ДЕНТИНА В ПОСТОЯННЫХ ИНТАКТНЫХ ЗУБАХ У ЗДОРОВЫХ ДЕТЕЙ И У ДЕТЕЙ С НЕСОВЕРШЕННЫМ ОСТЕОГЕНЕЗОМ

The article presents the results of studying the degree of mineralization of the peripulpal dentin in healthy children and in children with osteogenesis imperfecta according to the data of cone beam computed tomography. In teeth with malformations of heavy tissue tissues, in particular with imperfect osteogenesis, pathological changes are noted in the special enamel and dentin involved in teeth and root canals. The study of the observed characteristics of the distribution of peripulpal dentin in dangerous intact teeth and teeth with malformations of hard dental tissues is of great interest.
 Subject. Of the study is the degree of mineralization of the peripulpal dentin in permanent intact teeth in healthy children and in children with osteogenesis imperfecta. 
 Objectives. The degree of mineralization of periculpar dentin in children with osteogenesis imperfecta and in healthy peers in permanent intact teeth according to cone-beam computed tomography.
 Methodology. The study was performed at the Department of Pediatric Dentistry and at the Department of Radiation Diagnostics of the Moscow State Medical University named after A.I. Evdokimov in the Department of X-ray and Radiation Diagnostics of the CCCHLPHIS Clinic of the Moscow State Medical University named after A.I. Evdokimov. The study involved 22 patients aged 7 to 14 years.
 Results. In the group of children with imperfect osteogenesis in permanent molars with completed root formation, obliteration of the tooth cavity and wide root canals are noted. In the group of healthy children with permanent intact molars, no expansion of the tooth cavity and root canals was noted, no signs of root canal obliteration were detected. The average density of dentin in permanent molars in the group of healthy children is significantly higher than in children suffering from osteogenesis imperfecta.
 Conclusions. Cone-beam computed tomography is an objective method of visualizing the teeth of both jaws, which allows with minimal radiation load and high accuracy to determine the density of periculpar dentin in permanent teeth in children in one study. Pronounced violations of the mineralization of hard tissues of teeth in children with osteogenesis imperfecta and require further study as the child grows up at the stages of dental rehabilitation.

Early Childhood Caries and Sleep Disorders

Obstructive sleep-disordered breathing (oSDB) comprises a set of breathing disturbances when the individual is asleep due to partial or complete upper airway obstruction. Modifying or risk factors are the anatomy, the size and shape of the airway, muscle tone, central nervous system responses to hypoxia, etc. In children, this is associated with poor school performance and reduced memory and learning abilities. In addition, increased levels of blood and lung pressure and cardiac alterations have been reported in children with sleep disturbances. On the other hand, Early Childhood Caries (ECC) is defined as the presence of one or more decayed primary teeth (cavities) of children under the age of 5. This study aimed to establish the possible relationship between sleep disorders and ECC by means of validated surveys and determined whether the results obtained coincide with the available literature. Our results found that up to 24.5% of children with a high risk of caries present regular nasal congestion, while this finding is only present among 6% of children with a low risk of caries (p = 0.041). The dmft index remains significantly linked to this occasional congestion, but the association depends on the patient's level of risk (p = 0.008); increasing with a high increasing risk of caries. As a conclusion, the risk of early childhood caries could correlate to a specific sleep change such as occasional snoring.

Study on New Dental Materials Containing Quinoxaline-Based Photoinitiators in Terms of Exothermicity of the Photopolymerization Process.

Modern dentistry places great demands on the dental composites used for filling tooth cavities or treating cavitated tooth decay. The aim of the work was to modify the properties of composites by changing the initiators and co-initiators. This was achieved by using initiators based on a quinoxaline skeleton and co-initiators that are derivatives of acetic acid, which is an advantage of these photoinitiating systems due to the elimination of aromatic amines from the photocurable composition. The composites also differed in dental fillers. The effect of the compounds on the exothermicity of the photopolymerization process, the surface morphology of the obtained materials and the maximum compressive strength were determined. The photoinitiating capacity of the two-component systems was tested by the microcalorimetric method using the multifunctional monomer TMPTA, typical for dental filler compositions. The new photoinitiating systems show particularly good efficiency of free radical polymerization initiation, which occurs by the photoinduced intermolecular electron transfer (PET) mechanism. The comparison of the tested systems with camphorquinone, a photoinitiator traditionally used in dentistry, made it possible to observe a decrease in temperature during photopolymerization without a significant decrease in the polymerization rate or increase in photocuring time, as well as a better homogeneity of the surface of the obtained polymeric materials. This indicates that dye-acetic acid derivative systems may be useful in dental applications.

THE SEALING CAPACITY AND HEAT TRANSFER CHARACTERISTICS OF A STRAIGHT-THROUGH LABYRINTH SEAL WITH DIFFERENT GEOMETRIC PARAMETERS

The sealing capacity and heat transfer characteristics of the straight-through labyrinth seal with different geometric parameters are analyzed in this paper through numerical investigation. The geometric parameters studied include the gap width varying from 2 mm to 6 mm, the tooth tip thickness varying from 1 mm to 3 mm, and the front inclination angle varying from 75° to 100°. For each case, the Reynolds number is varied from 10,000 to 40,000. According to the results, the sealing performance is mainly influenced by the gap width, and less affected by the tooth tip thickness and the front inclination angle. As the gap width is increased, the discharge coefficient is increased by about 40%. With the tip thickness or the front inclination angle increased, the discharge coefficient is increased by less than 5%. For the heat transfer of the end wall, the gap width has significant effects, while the effects of the other two parameters are mainly in the first tooth cavity. For the stator, the increased flow rate at the tooth tip results in enhanced local heat transfer. For the rotor, the heat transfer is determined by the vortex intensity in the tooth cavity. The presence of small secondary vortices weakens the local heat transfer.

History of dental inlay

An inlay is a special filling that fits exactly into the tooth cavity, a filling cast from precious metal-gold or porcelain. Inlays have a relatively short history. This is one chapter of the Encyclopedia of the History of Dentistry.

Survival rate of the Hall technique compared with resin composite restoration in multi-surface cavities in primary teeth: a 1-year randomized clinical trial.

Hall technique (HT) has been indicated for teeth with dentinal caries lesion; however, extensive cavities, with more than two surfaces still seem challenging for restorative treatment in pediatric dentistry, resulting in a higher failure rate and an increased need for retreatment. To compare the survival rate of the Hall technique preformed metal crown (HT) with resin composite restoration (RC) for multi-surface cavitated caries lesions in primary molars. In this multicenter two-arm randomized clinical trial, children between 4 and 9 years of age with at least one primary molar with cavitated caries lesion involving more than two surfaces, including one buccal or palatal/lingual surface, were selected from 17 Brazilian cities. A total of 364 teeth were allocated into two groups: (1) teeth treated with selective caries removal and RC and (2) treated with the HT. The survival rate was assessed at 6 and 12 months after the interventions. Survival analysis was performed with the Kaplan‒Meier method. Cox regression was used to determine the influence of explanatory variables on the survival rate (α=5%). After 12 months, 292 teeth were re-evaluated. A total of 358 teeth were re-evaluated at least once during the study and included in the survival analysis. The HT (87.8%) resulted in a higher survival rate than RC restoration (75.7%) (p=0.004). HT has a higher survival rate than RC as a treatment for multi-surface cavitated caries lesions in primary teeth. ClinicalTrials.gov: NCT02782390.

Apically extruded debris, canal transportation, and shaping ability of nickel-titanium instruments on contracted endodontic cavities in molar teeth.

Apically extruded debris, canal transportation and shaping ability were compared between contracted endodontic cavities (CECs) and traditional endodontic cavities (TECs) after instrumentation with XP-endo Shaper (XPS), ProTaper Gold (PTG), ProTaper for hand-use (HPT) and Hero Shaper. The CECs or TECs groups were sub-divided into 24 groups according to root canal morphology and nickel-titanium (Ni-Ti) instruments. The weight of apically extruded debris was calculated using the Myers and Montgomery model. Pre- and postoperative images of teeth were scanned using micro-CT and the three-dimensional models were constructed and compared. Under CECs or TECs, XPS and PTG produced less apical debris and formed less canal transportation than HPT and Hero Shaper (P < 0.05). XPS group under CECs extruded less apical debris than that under TCEs for round canals with curvature of 20°-35° (P < 0.05). The centering ratios of four tested instruments were higher under TECs than those under CECs (P < 0.05). The HPT and Hero Shaper had more transportation under CECs than that under TCEs (P < 0.05). No statistical difference was found regarding shaping ability among all the groups. Under CECs, XPS preserves the original root canal anatomy, meanwhile it produces less apical debris than the other instruments.

Pulpal calcifications in orthodontically moved teeth: Scoping review.

The application of forces during orthodontic treatment can induce pulpal calcifications, characterized by the deposition of mineralized tissue in the pulp cavity space, there may be repercussions on dental procedures, especially endodontic treatment. The objective of this article is to map the scientific evidence and any gaps in knowledge regarding the relationship between orthodontics and dental pulp calcifications. The study comprised a scoping review whose guiding question was: "What is the scientific evidence of the association between pulpal calcifications and orthodontic treatment?" Two independent reviewers searched the PubMed, Scopus, and Web of Science databases and the grey literature. Original articles and observational and clinical trials, which addressed the repercussions on the pulp cavity of teeth submitted to orthodontic treatment, were included. There was no language restriction or limitation of the year of publication until October 2022. After critical reading and applying the eligibility criteria, 11 studies were included in this scoping review: six observational and five experimental studies. A statistically significant association of orthodontic treatment with changes in pulp cavity volume and increased incidence of pulp stones was observed among the studies findings. The orthodontic force can promote changes in the dental pulp that may cause direct implications in other dental treatments, especially endodontic treatment. Key words:Dental pulp calcifications, pulp node, pulp obliteration, orthodontic treatment, orthodontics.

Nonuniform Clearance Effects on Pressure Distribution and Leakage Flow in the Straight-through Labyrinth Seals

Straight-through labyrinth seal is a simple and reliable noncontact seal structure widely used in aeroengines. During the actual operation of aeroengines, the labyrinth seal clearance might experience a nonuniform variation in the flow direction due to asymmetric structure and uneven temperature. In order to characterize the degree of nonuniformity, the nonuniformity coefficient is defined in current paper. The effect of nonuniform causes (rotor deformation or stator deformation), nonuniform type (convergent clearance or divergent clearance), and nonuniformity coefficient (nonuniformity degree) is carefully studied by numerical simulation. Comparative analysis has shown that there is no obvious difference in flow coefficient (less than 0.8% in current studies) between two nonuniform causes. As for nonuniform type, the nonuniformity impact of divergent type on the flow coefficient is more significant than that of convergent type, as a result of stronger axial inertia. Pressure distributions of teeth cavities indicate that the total pressure drop of the divergent type is more obvious than that of the convergent type when the pressure ratio is the same. With the same dimensionless minimum tip clearance, clearance nonuniformity would result in the increase of leakage flow of the straight-through labyrinth, particularly for the condition with small pressure ratio, large circumferential Mach number, and small dimensionless minimum tip clearance. When the nonuniformity coefficient is within the range of -0.1 to 0.1, the variation curves of nonuniformity impact factor versus the nonuniformity coefficient almost coincide (the maximum deviation is no more than 1.2%) under different operation conditions (Reynolds number, pressure ratio, circumferential Mach number, and dimensionless minimum tip clearance). Current work proves it that the effect of seal clearance nonuniformity on the leakage flow requires special attention for the refined design of aeroengines.

Survival Rate of Atraumatic Restorative Treatment Restorations in Primary Posterior Teeth in Children with High Risk of Caries in the Republic of Kosovo-1-Year Follow-up.

Atraumatic restorative treatment (ART) may be beneficial for disadvantaged populations with no or limited access to dental services. This study aimed to evaluate the survival rate of single-surface ART restorations in primary posterior teeth in children with high caries risk. This study was conducted in six rural areas of the Republic of Kosovo, and 100 children aged 3 to 8 years participated in the study. Information was obtained from each parent/guardian regarding their children, such as sociodemographic characteristics, general health, dental history, dietary habits, oral hygiene, and fluoride exposure. The reduced Cariogram was used to estimate the risk of caries in the participants based on the seven factors specified in the program, and all the provided information were collected and entered in a computer program of the Cariogram. A pediatric dentist, accompanied by two assistants, performed 100 ART restorations in school settings using high-viscosity glass-ionomer cement (Fuji IX) following the nine steps of the ART procedure. The restorations were evaluated at 3, 6, 9, and 12 months using the ART restoration criteria. Percentages, mean value, standard deviation, mean interquartile range, and difference test between arithmetic mean values were used to analyze the research results. Review of the average of reduced Cariogram showed that the majority of children, 72%, were at high risk of developing caries, with only 28% having a good chance of avoiding caries in the future. A total of 77% of the children in the study had never visited dentists before due to poor economic conditions and the lack of dentists in the area. The success rates of ART restorations performed in single-surface cavities in primary teeth were very encouraging, with more than 97% success rates after a 1-year follow-up period. Our results demonstrate that ART is efficient, affordable, and practical for the treatment of single-surface cavities in primary posterior teeth. Owing to its low price and atraumatic nature, ART can potentially help disadvantaged children in Kosovo access dental care.

Human behavior is a set of behaviors that humans have that are influenced by customs, value, ethics, attitudes, emotion, power, persuasion, and/or genetics. Oral hygiene is a form of dental hygiene. Toddler often suffer from oral and dental problems such as tooth decay or cavities. Hence, parental behavior towards the oral hygiene of toddler is urgently needed. This study aims to determine the factors that significantly influence maternal behavior on oral hygiene in toddler and to obtain a model of maternal behavior using Bayesian logistic regression method. Bayesian method estimation is solved using Markov Chain Monte Carlo (MCMC) simulation. The results of this study indicate that the variables of knowledge and income have a significant impact on maternal behavior in maintaining oral hygiene in toddler.

Effect of radiant emittance of an LED curing light on the cuspal deflection of a simulated tooth cavity in bulk-fill composite restoration: A novel simulation method.

In this study, a novel method for simulating human teeth was developed, with which the effect of radiant emittance of an LED curing light on the cuspal deflection was investigated. A mesio-occluso-distal (MOD) cavity was replicated using a heat-pressed ceramic and lost wax technique, and the cuspal compliance and cuspal deflection of the replicated ceramic teeth and extracted human teeth were evaluated. The replicated ceramic teeth were restored using a nano bulk-fill composite and photopolymerized using three different protocols. Data were analyzed with t-test and one-way ANOVA (α=0.05). The cuspal compliance and cuspal deflection of the replicated ceramic teeth and extracted human teeth were similar. Cuspal deflections did not differ significantly among the tested photopolymerization protocols. Thus, the replicated ceramic teeth were an effective simulation of human teeth. During bulk-fill composite restoration of the MOD cavity, cuspal deflection was not affected by changing the radiant emittance of the LED light.

Evaluation of fracture resistance in class II tooth cavity using different techniques.

It is of interest to evaluate the fracture resistance of endodontically and non-endodontically treated teeth with class II cavity using different techniques and materials. Endodontic access cavities were prepared with the diamond fissure bur following the MOD cavity preparations,. The root canals preparation was done followed by obturation using the single cone obturation technique. Later all the samples were embedded in acrylic resin blocks and divided into 8 groups; Group 1: -Intact teeth (Control), Group 2: - MOD (unfilled), Group 3: - MOD restored with composite resin (3M FILTEK P-60 packable), Group 4: - MOD restored with Cention N (Ivoclar Vivadent), Group 5: - 10 mm fiber-post with composite resin, Group 6: - 5mm fiber post with composite resin, Group 7: - Ribbond on the occlusal and composite resin, and Group 8: - Horizontal fiber post with composite resin. Later all samples were subjected for fracture resistance testing using Universal Testing Machine. The mean fracture resistance of Control (513.2 N), Unfilled (60.2N), composite resin (221 N), cention N (88.9 N), 10 mm fiber post (271.4 N), 5 mm fiber post (245 N), Ribbond (456.4N), and horizontal fiber post (338.1N) was found. The fracture resistance values are statistically significant between each group. Best fracture resistance was found to be of intact teeth followed by ribbond on the occlusal surface after endodontic treatment and least fracture resistance of MOD unfilled. Thus, ribbond method is good for the occlusal of teeth compared to other materials for fracture resistance.

Learning Clinical Skills Using Haptic vs. Phantom Head Dental Chair Simulators in Removal of Artificial Caries: Cluster-Randomized Trials with Two Cohorts' Cavity Preparation.

Dental task trainer simulators using haptics (virtual touch) offers a cost-effective method of teaching certain clinical skills. The purpose of this study is to evaluate students' performance in removing artificial caries after training with either a haptic dental chair simulator with virtual reality or a traditional dental chair simulator with a mannequin head. Cluster Randomized Controlled Trials in two cohorts, both Year 1 dental students. Students taught using traditional dental chair simulators were compared with students taught using haptic-based simulators on their ability to cut a cavity in a plastic tooth following training. Across both cohorts, there was no difference in the quality of cavity cut, though students' technique differed across the two simulator groups in some respects. No difference was seen across both cohorts in the quality of cavity cut for a simple preparation, though students in the haptic condition performed less well in the more demanding task. Moreover, students in the haptic group were also less likely to be perceived to be 'holding the instrument appropriately'. These findings suggest further investigation is needed into the differences in handling of instruments and level of clinical task difficulty between the simulators.

Safe, supportive neighborhoods: Are they associated with childhood oral health?

There has been limited examination of how community-level supports may influence oral health metrics among children. The purpose of our study is to examine the association between two types of community-level positive childhood experiences and oral healthcare and oral health outcomes among children ages 6 to 17 years of age. This study uses a cross-sectional data set from the 2018-2019 National Survey of Children's Health. Two oral health metrics were used: preventive dental care, measured as one or more preventive dental visits in the past 12 months, and tooth decay, measured as tooth decay or cavities in the last 12 months. To quantify living in safe, stable, equitable environments, questions on residing in a safe and supportive neighborhood were used. Descriptive statistics and bivariate analyses were used to calculate frequencies, proportions, and unadjusted associations for each variable (n=40,290). Multivariable logistic regression models were used. In an adjusted analysis, children who lived in a supportive neighborhood had a higher likelihood of receiving a preventive dental visit than children who did not live in a supportive neighborhood (aOR 1.41; 95% CI 1.21-1.65). Children who lived in a safe neighborhood were less likely to have tooth decay than children who did not live in a safe neighborhood (aOR 0.75; 95% CI 0.65-0.86). The findings from this study highlight the role of social structures in tightening the safety net for oral healthcare in children.

Adjunctive therapies for in vitro carious lesions: Antimicrobial activity, activation of dentin metalloproteinases and effects on dental pulp cells

BackgroundAdjunctive therapies used before dental restorative procedures may encourage carious tissue removal. Beyond promising antimicrobial properties, treatments could positively modulate the dentin-pulp complex while not interfering with restoration survival. Herein, we evaluated a set of substances and their effects on carious lesions and the underlying dentin or pulp cells. MethodsArtificial caries lesions were developed in bovine teeth cavities immersed in Streptococcus mutans and Lactobacillus casei co-cultures. The cavities were treated according to the following groups: Phosphate Buffer Saline (PBS), Chlorhexidine (CHX), Papacárie® (Papain gel), Ozone (O3), and antimicrobial Photodynamic Therapy (aPDT). After treatments, samples were cultivated to count isolated microbial colonies. The zymography assay evaluated the activity of dentin metalloproteinases (MMP-2 and MMP-9). Cell viability was indirectly assessed on human dental pulp cells after 24, 72, or 120 h, whereas the odontodifferentiation potential was evaluated after ten days of cell culture. ResultsCHX and aPDT led to around 1 log bacterial load reduction. PBS, CHX, and aPDT showed the eventual expression of MMP-2 and MMP-9. Cell viability was reduced (< 30%) after 120 h for all groups compared to the control. CHX, O3, and aPDT induced greater odontodifferentiation (≈ 20% higher) than PBS and papain gel. ConclusionAdjunctive therapies presented little or no biological significance in reducing bacterial load in artificial carious lesions. Although the activation of endogenous metalloproteinases may represent a possible concern for adhesive restorations, some of these treatments may have a positive role in dental pulp tissue repair.

Photochemically Driven Polymeric Biocompatible and Antimicrobial Thiol-Acrylate Nanocomposite Suitable for Dental Restoration.

The development a photochemically driven polymeric composite for dental restorative materials to restore tooth cavities with antibacterial, biocompatibility, and outstanding mechanical properties is an urgent need for clinical application in stomatology. Herein, a series of polyurethane acrylate (PUA) prepolymers and antibacterial polyurethane acrylate quaternary ammonium salts (PUAQASs) were synthesized, and their mechanical and biological properties were explored. The unique secondary mercaptan with a long shelf life and low odor was used to reduce oxygen inhibition and increase cross-linking density; meanwhile, modified photocurable nano zirconia (nano ZrO2) enhances mechanical properties of the nanocomposites and possesses preeminent dispersion in the matrix. The results show that minimal inhibitory concentrations (MICs) of PUAQASs are 200 and 800 μg/mL for Staphylococcus aureus and Escherichia coli, respectively. The addition of secondary thiols significantly increases the photopolymerization rate and monomer conversion. The highest hardness and modulus reach 1.8 and 8.7 GPa compared to 1.8 and 8.3 GPa for commercial resin. The lap shear stress on the pig bone is 912 MPa, and that on commercial resin is 921 MPa. Most importantly, the photochemically driven polymeric composite has excellent biocompatibility and significantly better antimicrobial properties than commonly used commercial resins.

DENTAL STATUS OF BRONZE AGE POPULATION FROM THE AREA OF MODERN POLTAVA REGION (ACCORDING TO THE ANTHROPOLOGICAL MATERIALS)

In modern medical science, and in particular in dentistry, regarding pathology, the following question is actual invariably: Have there always been manifestations of diseases as we see them today? At the same time, research on dental diseases in ancient people remains also a reliable source of knowledge about the causes of oral cavity pathology in the modern population.&#x0D; Therefore, it is important to study deviations from the norms of development and peculiarities of skeleton of populations in various periods.&#x0D; The purpose of the study. To investigate the condition of hard oral tissues in the Bronze Age population from the area of modern Poltava region by skeletal remains.&#x0D; Object and methods of research. For the analysis the bone remains of 47 representatives (4 children's, 20 women's and 23 men's skeletons) of population of the Bronze Age (middle of the 3rd millennium – the 2nd millennium BC), from the area of modern Poltava region (main group), from the mound located in the vicinity of the village Hittsi of the Lubenskyi district, discovered by the archeological expedition in 2021 were selected.&#x0D; Anthropological series of individuals living in the Bronze Age on the territory of modern Poltava region described earlier were taken as a control group for comparison.&#x0D; The materials were discovered during the archaeological excavations carried out in 1998-2012, where a total of 102 skeletons were examined (30 children's skeletons, women's skeletons among examined are 20, and male ones are 52.)&#x0D; The study of the material was carried out by the method of skeletal tissue analysis of ancient people, developed by the authors of this publication on the basis of the Laboratory of Medical and Historical Anthropology of the Municipal Establishment "Center of Protection and Research of Archaeological Monuments" of Poltava Regional Council and the Children's Department of Therapeutic Dentistry with prevention of dental diseases of Poltava State Medical University. The method provides maximum preservation of bone and teeth tissues.&#x0D; Research results. Differences in the dental status of the main group correspond to the results of the paleopathological analysis of the collective anthropological series of the Bronze Age control group from the area of Poltava region (where there were found 4 tooth cavities per 102 persons and in another 22 persons dental mineralized deposits were observed) which reflect a specific consequence of the negative impact of social factors and environment in places of residence. However, the difference was determined in the form of coverage of the chewing organs with teeth mineralized deposits. Discrepancy in the number of encounters of mineralized deposits in the teeth of the studied groups is probably explained by the difference in food consumption and possible differences in types of lifestyles, the possible tendency of the male population to long transitions.&#x0D; Conclusion. The general somatic status of the control group of the studied people corresponds to the state of health of the Bronze Age population of the main group from the area of Poltava.&#x0D; So, another 47 people of the Bronze Age showed the same dynamics of the development of dental pathology with previously studied skeletons of representatives of this time from the area of the modern Poltava region.
