The need for orthopedic dental services for the elderly population of Kazakhstan

<b>Objective</b>: To determine the orthopedic dental status of the elderly population of Kazakhstan using clinical and diagnostic determinants.<br /> <b>Methods:</b> The dental status of 708 patients from three institutions in Almaty, Kazakhstan, was recorded using WHO dental questionnaires. The patients were divided into groups according to their age and sex, and modern statistical methods were used to process the data. Through the construction of tables and graphs, calculation of relative values, and assessment of the reliability of the differences in the data, we determined if there were any differences between the groups.<br /> <b>Results: </b>The study revealed that most patients who needed orthopedic dental care were 60 years of age and older. The older the age of patients with registered diagnoses of partial and complete adentia, the greater the need for removable prosthetics. The most common type of orthopedic treatment required for these patients was removable dentures. Analysis of the quantitative relationship between the need for orthopedic dental care and patients’ gender revealed the following patterns: the critical value of Chi-square at the significance level p≤0.0001 was 23.95, the exact Fisher criterion was 0.0000 (p=0.0000), and the calculated Cramer’s V criterion and the conjugacy coefficient showed the relationship between the variables were at the levels of 0.17 and 0.18, respectively.<br /> <b>Conclusions:</b> Owing to the aging population in Kazakhstan, and indeed the world, the problem of medical adaptation and social rehabilitation of older age groups is pertinent, and our findings argue that the introduction of geriatric dental services in Kazakhstan is warranted.

Social status and oral health in early medieval Switzerland: The case of the Baar-Früebergstrasse site (Canton Zug, Switzerland)

Grave goods do not always reflect the socioeconomic status of the buried people when they were living, so the interpretation of these archeological items may be biased. This paper examines the oral pathologies of individuals (n = 36) from the early medieval cemetery at Baar-Früebergstrasse (Switzerland) and explores the relationship between these pathologies and grave status. The analysis focused on dental parameters such as tooth wear, caries, and periodontitis, among others. Only lower teeth were analyzed. While the general dental status between individuals buried in wealthy and standard graves appear to be very alike, some interesting patterns emerged. Tooth-wear values were similar among sexes and grave goods categories, suggesting a common diet. The incidence of caries was generally low in the studied individuals and grave status does not appear to have a significant influence on this. In addition, alveolar bone status showed significantly different values for the two social groups. These results suggest that no clear dietary differences can be assumed for individuals found in wealthy and standard graves at Baar, given the very similar nature of their oral conditions. However, the limited sample size of the wealthy group necessitates caution in generalizing these results. Further research with larger sample sizes can provide a more comprehensive understanding of oral health disparities associated with socioeconomic factors in the Early Middle Ages.

Legacy lessons from the COVID-19 era to improve trial participation and retention: Views from trial participants, PPIE contributors and trial staff across the NIHR portfolio.

The Covid-19 pandemic had a profound effect on the delivery of healthcare research. Covid-19 research was prioritised and many non-essential trials were paused. This study explores the engagement experiences of trial participants', PPIE contributors' and trial staff during the Covid-19 pandemic and towards recovery and restoring a diverse and balanced UK clinical trials portfolio. Interviews and focus groups were undertaken with PPIE contributors, trial participants and trial staff members from NIHR research trials across the UK (November 2020-June 2021) across portfolio specialities: Cancer, Oral and Dental Health, Musculoskeletal Disorders, Cardiovascular Disease, Neurological Disorders, Primary Care, and Conditions associated with susceptibility to Covid-19 (Diabetes, Stroke, Respiratory Disorders). Topic guides were developed for each participant group and interviews were conducted over Zoom. The transcripts were analysed using codebook thematic analysis in NVivo (V.12). 106 participants comprising, 45 PPIE contributors, 27 trial participants and 34 trial staff members were recruited. Three themes to engagement with trials during Covid-19 were developed. 1) Ensuring continued contact. Continued and tailored communication, having a trial point of contact and regular updates all enhanced trial engagement and retention. Patients' unfamiliarity with materials being sent electronically reduced engagement and trust. 2) A balanced move to remote consultations. Remote follow-up and monitoring were convenient and allowed for wider recruitment across the UK. Participants were more likely to discuss personal subjects in their own homes. Remote visits lacked a personal touch, some concerns over missed diagnoses or being unable to appreciate the situation, technical abilities or equipment failures were seen as barriers, especially for disadvantaged or older people. 3) The importance of feeling fully informed. Factors that supported attendance were knowledge about trial conduct adherence to Covid-19 regulations, social distancing, clear signage at the site and opportunities to ask questions. Barriers included not knowing what to expect and not feeling safe with rules and regulations. Our findings highlight a number of ways to future proof trial delivery against future pandemics or disruptions such as offering online options to participate in research, ensuring consistent communication between participants and the research team, making sure participants feel fully informed and the continued reassurance of safety in the clinical setting.

The Use of Eye-Tracking Technology in Dento-Maxillofacial Esthetics: A Systematic Review.

The use of eye-tracking technology in dental esthetics has gained popularity over the past decade because of its ability to assess observers' visual preferences in an objective manner. The goal of this study was to provide a comprehensive review of eye-tracking studies in dentistry, which could provide a reference for the rational and effective application of eye-tracking technology by dentists in the future. A comprehensive search of articles on eye tracking, published from January 1946 to June 2023, was conducted across several databases using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The major criterion for inclusion was that the study evaluated the use of eye-tracking technology in the field of dentistry. Two independent reviewers screened the eligible studies. A total of 67 articles were identified, 41 of which met our inclusion criteria. The most common application of eye tracking was the assessment of perceptions of changes in specific dental conditions among different classes of observers. Overall differences between groups (different classes of observers, different types of conditions) among different areas or regions of interest were analyzed. This systematic review demonstrated the utility of eye-tracking technology as a quantifiable objective assessment and emerging research tool for evaluating outcomes in several domains of dentistry.

Evaluating the Impact of Teledentistry on Patient Outcomes, Diagnostic Accuracy, and Satisfaction in a Prospective Observational Analysis.

Background Teledentistry, defined as the use of telecommunication technologies for dental care, has emerged as a transformative approach to oral health services. This prospective observational analysis aims to comprehensively assess the impact of teledentistry on patient outcomes and satisfaction, addressing key aspects such as diagnostic accuracy, longitudinal treatment outcomes, and economic and logistical considerations. Methods The study involved 242 participants selected from diverse dental clinics offering teledentistry services. Participants could choose between traditional in-person visits and teledentistry consultations. The teledentistry interventions included remote consultations, diagnostic evaluations, and treatment planning facilitated through virtual communication tools. Baseline assessments captured initial dental conditions, and follow-up assessments were conducted at three, six, and 12 months. Outcome measures included diagnostic accuracy, patient satisfaction, changes in dental conditions over time, and economic and logistical feedback. Results Descriptive statistics revealed baseline characteristics, with participants evenly distributed between in-person and teledentistry groups. However, the overall satisfaction with diagnoses was significantly lower in the teledentistry group as compared to the in-person group (p < 0.001). Longitudinal assessments demonstrated comparable changes in dental conditions between the two groups. Economic feedback highlighted a cost-saving advantage for teledentistry users, with 80% reporting reduced expenses. Conclusion This study highlights the transformative potential of teledentistry in expanding access to oral health services, reducing costs, and providing comparable treatment outcomes to traditional in-person care. Future efforts should focus on enhancing the teledentistry experience, addressing patient satisfaction concerns, and refining the delivery of remote dental care to maximize its benefits for both patients and healthcare systems.

РАСПРОСТРАНЕННОСТЬ КАРИЕСА ЗУБОВ И ЗАБОЛЕВАНИЙ ПАРОДОНТА У ДЕТЕЙ С НАРУШЕНИЕМ СЛУХА (ОБЗОР ЛИТЕРАТУРЫ)

Subject. Deafness, hearing loss are one of the most common sensory pathologies in children. It negatively affects the formation of personality and quality of life. Children with hearing and speech impairments require special medical supervision. It is necessary to develop programs to prevent major dental diseases for deaf children. This requires a comprehensive assessment of the dental status, taking into account age, the severity of the main pathology, and socio-psychological factors that contribute to the development of the formation characteristics of the child’s body.&#x0D; Purpose. To analyze the prevalence and intensity of dental caries and periodontal diseases in children with hearing impairment according to various literature data.&#x0D; Methodology. An analysis of publications was carried out using scientific search library databases: PubMed Central, Google, Medline, eLibrary. The selection of materials was based on using keywords. The search included full-text articles. 36 sources were analyzed.&#x0D; Results. Analysis of the prevalence of dental diseases in children with hearing impairment has not been sufficiently published in Russian-language literary sources.&#x0D; According to various literature data, there is a high prevalence of caries and periodontal diseases in children with hearing impairment. Some authors compared these indicators with a group of healthy children. Children with hearing and speech impairments have higher rates of prevalence and intensity of caries and periodontal diseases.&#x0D; Conclusions. The high prevalence of dental diseases in children with hearing impairment is an additional medical and social problem. For this category of the population, it is of great importance for the development of prevention programs.

ПРЕДОПЕРАЦИОННАЯ ДИАГНОСТИКА У ПАЦИЕНТОВ С ЗАБОЛЕВАНИЯМИ СЕРДЕЧНО-СОСУДИСТОЙ СИСТЕМЫ ПЕРЕД ОПЕРАЦИЕЙ ДЕНТАЛЬНОЙ ИМПЛАНТАЦИИ (ОБЗОР ЛИТЕРАТУРЫ)

The subject of the study. Dental implantation for patients with cardiovascular diseases is an urgent and important area, but requires special attention from doctors and patients. Cardiovascular diseases can be a risk factor for implant rejection due to the fact that they often have a direct effect on blood flow to tissues. A review of literature sources in the period from 2017 to 2023 showed that there is no common point of view in the scientific community regarding the implementation of implantation in patients with hypertension and coronary heart disease. &#x0D; Objectives. To study the specifics of preoperative diagnosis in patients with cardiovascular diseases before dental implantation surgery, reflected in the scientific literature. &#x0D; Methodology. Currently, the article analyzes sources from databases: Pub Med, Cyberleninka, eLibrary, ResearchGate, CohraneOral Health. The search for scientific literature on the problem under consideration was carried out using keywords. The key criteria for reviewing the scientific publications available in the databases were the availability of indications for dental implantation in the studied individuals.&#x0D; Results. An analysis of the scientific literature on the use of dental implantation in patients with diseases of the cardiovascular system did not reveal a single point of view. The authors agree that patients with cardiac pathology need to hold a consultation with a cardiologist, an anesthesiologist, and a surgeon before elective surgery in order to make a joint decision. At that time, there are different points of view regarding the criteria for assessing the risk and scope of preoperative diagnosis of patients with cardiovascular diseases, there is no systematization and classification of complications, as well as criteria for evaluating the complications of dental implantation surgery in cardiac patients. &#x0D; Conclusions. It seems advisable to identify criteria that determine the general condition and dental status of patients with diseases of the cardiovascular system, which will allow assessing the possibility of using dental implants for them.

Assessment of Nutritional Status and Correlation of Factors With Body Mass Index of Cancer Patients: A Cross-Sectional Study.

Decreased diet intake and malnourishment have profound implications on cancer patients' quality of life and survival. Malnutrition increases the risk of postoperative complications, increases hospital length stays, reduces patient's tolerance to radiation and chemotherapy treatment, and results in poor response to treatment. In the present study, we intended to assess the nutritional status of cancer patients and find the correlation of body mass index with anthropometric and blood parameters. The study was prospective and cross-sectional, and 104 patients with newly diagnosed solid tumors were included. Patient demographics, symptoms, and anthropometric and blood parameters were collected. The correlation was estimated with Pearson's correlation coefficient. A p-value of less than 0.05 was considered significant. The association between stages of the disease, dental status, type of diet, and BMI was p=0.701, 0.216, and 0.422, respectively, and was not statistically significant. The anthropometric parameters mid upper arm circumference (MUAC cm), mid arm circumference (MAC cm), and triceps skinfold thickness (TSF mm) correlated with body mass index (BMI kg/m2) and had statistically significant p values of 0.0001, 0.0001, and 0.033, respectively. The correlation was assessed between hemoglobin, red cell distribution width, neutrophil-to-lymphocyte ratio, and serum albumin levels with BMI, but except for albumin (p=0.05), no other blood parameter correlated. Nutritional assessment is vital in recognizing patients at risk of treatment-associated complications and poor responders to treatment. In this study, BMI correlated with anthropometric parameters MUAC, MAMC, and TSF. Baseline dietary assessments of patients will help focus on the nutritional build-up of patients before starting treatment.

A Proof of Concept: Optimized Jawbone-Reduction Model for Mandibular Fracture Surgery.

Previous research on computer-assisted jawbone reduction for mandibular fracture surgery has only focused on the relationship between fractured sections disregarding proper dental occlusion with the maxilla. To overcome malocclusion caused by overlooking dental articulation, this study aims to provide a model for jawbone reduction based on dental occlusion. After dental landmarks and fracture sectional features are extracted, the maxilla and two mandible segments are aligned first using the extracted dental landmarks. A swarm-based optimization is subsequently performed by simultaneously observing the fracture section fitting and the dental occlusion condition. The proposed method was evaluated using jawbone data of 12 subjects with simulated and real mandibular fractures. Results showed that the optimized model achieved both accurate jawbone reduction and desired dental occlusion, which may not be possible by existing methods.

Prevalence and correlation with sex, age, and dental status of bone apposition at the mandibular angle and radiographic alterations of the temporomandibular joints: a retrospective observational study in an adult Swiss population

BackgroundThe purpose of this study was to determine the prevalence of radiographic changes in the mandibular angle (bone apposition) and osseous alterations in the temporomandibular joints (TMJs) in the adult population of Switzerland. In addition, the study intended to investigate possible correlations between the two sites of contour bone changes (mandibular angle and TMJ) and to analyze various patient-related factors, including sex, age, dental status, and medical history.MethodsPanoramic radiographs of 600 patients distributed into six age groups (283 females, 317 males, aged 20 to 79 years) were included to evaluate radiographic changes. The bone in the mandibular angle region and the shape of the condylar heads were examined for contour changes (bone apposition at the jaw angles and osseous changes of the TMJs). General estimating equations, binormal tests, and chi-squared tests were used for statistical analysis.ResultsApproximately half of the mandibular angles (47.8%) showed bone apposition, mostly bilateral. TMJ alterations were less common (27%), often unilateral, with flattening being the most frequent finding. No significant correlation was found between the two sites. Bone apposition at the mandibular angle showed a significant male predominance, whereas TMJ changes did not differ by sex. Alterations in both sites increased with age, and were not related to dental status or analgesic use.ConclusionsBone apposition at the mandibular angle should be interpreted as part of the natural functional adaptation of the bone associated with aging. Assuming that parafunctional habits may influence the development and progression of alterations in the mandibular angle or TMJs, the presence of radiographic changes in these areas should prompt dental clinicians to investigate further in this direction.Trial registrationThe study was approved by the Swiss Association of Research Ethics Committees (swissethics), BASEC reference number: 2020–00963 (25.05.2020).

The relationship of one-sided chewing with status Dental and oral hygiene in the community Age 30-40 years Lingkungan Simae Baranti Sub-district, Sidrap Regency

Chewing food with one side of the mouth will cause thick and strong muscles only on that side. The facial muscles on the right and left sides will become asymmetrical. Chewing one side is one of the bad habits that can affect the hygiene status of teeth and mouth. Dental and oral hygiene can be measured by an index with good, medium, bad criteria. The measurement used is with OHI-S (oral hygiene index simplified).. This study aims to determine whether there is a one-sided chewing relationship with dental and oral hygiene status in people aged 30-40 years, Simae Environment, Baranti District, Sidrap Regency. This type of research is descriptive correlative with a cross sectional approach. Sampling was carried out using purposive sampling techniques and obtained 44 respondents. The results of the correlative descriptive test showed that there was a relationship between one-sided chewing and OHI-S status in people aged 30-40 years, Simae Environment, Baranti District, Sidrap Regency, namely chewing using one side by 72.7% of medium criteria.

Occurrence of Depression and its Association with Oral Health in Elderly People Living in Old Age Homes of Mathura.

Depression can affect oral health as a result of neglecting oral hygiene procedures which leads to an increased risk of dental caries and periodontal disease. To determine relationship between oral health and depression among elder people residing in old age homes of Mathura city. The study was conducted among 500 subjects aged ≥60 years where dental condition, number of missing teeth, removable denture wearing, teeth mobility, periodontal condition, pocket depth, loss of attachment, and depression according to the Patient Health Questionnaire-9 scale were assessed. Regression analysis showed a positive relationship of the PHQ-9 value with DMFT and MT. Among people aged 60 years and over, severity of depression increased with higher number of MT and DT.

The Role of Teleconsultations in Remote Oral Radiology Interpretation.

Teleconsultations have gained prominence as a viable method for delivering medical services remotely. In oral radiology, the ability to interpret radiographic images accurately is crucial for diagnosing and treating various dental conditions. The use of teleconsultations in this domain holds promise for extending specialized care to patients who are geographically distant from dental healthcare facilities. A total of 50 patients' oral radiographic images were collected for analysis in this study. These images were obtained from diverse geographical locations, showcasing the applicability of teleconsultations. Two groups of dental professionals, one conducting in-person evaluations and the other performing remote interpretations through teleconsultations, participated in the study. The radiographic findings were assessed for concurrence between the two groups. Statistical analysis included the calculation of P values to determine the level of agreement between the in-person and teleconsultation interpretations. The results of this study revealed a substantial level of agreement between in-person and teleconsultation interpretations of oral radiographic images. The calculated P values indicated a statistically significant concordance between the two evaluation methods (P < .05). This suggests that teleconsultations can be a reliable approach for oral radiology interpretation, offering comparable results to traditional in-person evaluations. In conclusion, teleconsultations have demonstrated their potential as an effective means of interpreting oral radiographic images remotely.

Does information about MIH on dental homepages in Germany offer high quality? A systematic search and analysis

PurposeThe internet is increasingly used to seek health information. A dental condition of increasing concern and public interest is molar incisor hypomineralisation (MIH), why we evaluated the information quality of German dentists ‘websites on the topic of MIH.MethodsA systematic search was performed by two independent investigators using three search engines. The information content of websites on MIH and technical, functional aspects, overall quality, and risk of bias were assessed using validated instruments (LIDA, DISCERN). Practice-related characteristics (practice type, specialization, setting, number and mean age of dentists) were recorded, and associations of these characteristics with websites’ overall quality were explored using multivariable linear regression modelling.Results70 sites were included. 52% were multipractices in urban areas (49%). The most common age group was middle-aged individuals (41–50 years). The average number of dentists/practice was 2.5. The majority met more than 50% of the DISCERN and LIDA criteria (90%, 91%). The MIH definition was frequently used (67%), MIH symptoms were described (64%), and 58% mentioned therapies. The prevalence of MIH was mentioned less frequently (48%). MIH example photographs were rarely shown (14%). In multivariable analysis, most practice-related factors were not significant for overall site quality. Only chain practices had slightly higher quality in this regard (2.2; 95% CI of 0.3–4.1).ConclusionsMIH is mentioned on a large proportion of dentists’ websites. Overall technical, functional, and generic quality was high. Risk of bias is limited. While most websites provided a basic definition of MIH and its symptoms, important information for patients was missing.

Self-assessment of dental health status, behaviours and oral health risk factors among adolescents from public schools in Maputo City-Mozambique

Self-assessment of dental health status may have an impact on the oral health behaviour of adolescents which could impact their oral health. Oral health has been linked to various medical health conditions, thus eliminating oral health diseases can improve general health. The present study aimed to assess the association between behaviours and risk factors (oral hygiene habits, sugar intake, urban/rural status) and negative self-perception of dental health status among adolescents attending public schools in Maputo City.Method An analytic cross-sectional study, conducted in three Primary public schools from urban and peri-urban areas in Maputo City selected by convenience due to their geographic location was included. The size of the sample was 236 12-year-olds. Data was collected using a self-completion questionnaire designed by the World Health Organization (WHO). Chi-square tests or Fishers’ Exact tests were used for associations. A simple and multiple logistic regression was used to determine the strength of these associations using backward elimination (p < 0.05). Results: The sample consisted of 221 adolescents, with 114 (51.6%) residing in urban areas and 107 (48.4%) in peri-urban areas. More than half of the participants (111 individuals) reported having a negative perception of their dental health. In the urban location, a higher percentage of participants had a “negative” perception of dental health (57.9%, n = 66), while in the peri-urban location, more participants perceived their dental health as “positive” (57.9%, n = 62). Participants residing in an urban setting were 82% more likely to have a negative perception of dental health (AOR = 1.82 [95% C.I.: 1.05 to 3.14]). Those who had experienced dental pain tended to report a higher proportion of negative dental perception (57.2%, n = 91), with 2.7 times more likely to report a negative perception of dental health (AOR = 2.72 [95% C.I.: 1.46 to 5.08]). The majority (n = 139; 63.2%) claimed to clean their teeth twice a day.Conclusion There was a higher negative perception of dental health in urban areas. The need to strengthen oral health promotion in urban schools is high since schools play such a significant role in oral health promotion.

Evaluation of oral health status in the population above 50: evidence from the ardakan cohort study on aging (ACSA)

BackgroundThe global population is undergoing rapid aging, and older individuals are more susceptible to various health issues, including oral health problems. Despite the increasing attention given to healthy aging, oral health has often been overlooked in discussions related to health problems. This study aims to assess the oral health status of middle-aged and older adults in Iran.MethodsThis cross-sectional study analyzed data from 4970 men and women aged 50 years and above, who participated in the Ardakan Cohort Study on Aging (ACSA) between 2020 and 2022. Trained personnel administered a questionnaire and conducted oral health examinations to determine the oral health status and oral hygiene behaviors of the participants.ResultsThe mean value (SD) of the total Decayed, Missing, and Filled Teeth (DMFT) index was 21.3 (10.7). Approximately 46% of all participants were completely edentulous (without natural teeth). Moreover, 58.5% of the total sample wore dentures, and the mean age (SD) when they started using dentures was 48.5 (20.7) years. About 71% of participants with natural teeth reported brushing their teeth at least once a day, while about 63% of denture wearers cleaned their dentures daily. In the sample, 28% of individuals had visited a dentist in the last year. The prevalence of difficulty in biting and chewing food among the participants was 48.2% and 44.6%, respectively. Additionally, nearly 68% of all samples reported experiencing at least one difficulty in daily functioning due to oral/dental conditions. The study identified cutoff points of seven (sensitivity = 56.8 and specificity = 77.5) and 10 (sensitivity = 72.1 and specificity = 71.1) missing teeth, indicating the presence of at least one problem in daily functioning due to oral/dental conditions in middle-aged and older adults, respectively.ConclusionThe study reveals a high prevalence of edentulism and denture use among participants aged 50 years and above. The majority of samples reported difficulties in daily functioning due to oral and dental conditions, especially in biting and chewing food. These findings highlight the importance of proactive measures to address oral health issues in middle-aged and older adults, thereby enhancing their overall health and well-being.

СПЕКТР МИКРОФЛОРЫ ПАРОДОНТАЛЬНОГО КАРМАНА У ПАЦИЕНТОВ С ХРОНИЧЕСКИМ ПАРОДОНТИТОМ СРЕДНЕЙ СТЕПЕНИ ТЯЖЕСТИ

The purpose of the study. To evaluate the quantitative composition of the microflora of the periodontal pocket in patients with chronic generalized periodontitis of moderate severity. Materials and methods. The study group included 39 patients, of which: 41% (16/39) were men, 59% (23/39) were women, with chronic generalized periodontitis of moderate severity at the age of 48.9±2.3 years. To determine the dental status, clinical research methods were used (questioning, examination), determination of the Green-Vermillion Oral Hygiene Index (OHI-S), (PMA) modified by Parma, the Mulleman-Cowell bleeding index, the degree of pathological tooth mobility was determined using the Miller scale (Miller) modified by Flesar, the complex periodontal index (CPI), identified furcation defects according to the classification of Lindhe J. (1983).Quantitative assessment of the periodontal pockets microflora was performed. Reagent kits “RIBO-prep” (Next-Bio LLC, Russia), DENTOSKRIN® (NPF Litech LLC, Russia) were used to isolate RNA/DNA from clinical material and subsequent analysis by polymerase chain reaction. Spectrum of identifiable bacteria: Porphyromonas endodontalis, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia, Tannerella forsythia.The results of the study and their discussion. Fusobacterium nucleatum was found in 84.6% (33) of patients in periodontal pockets, 30.8% (12) – Treponema denticola, 28.2% (11) – Prevotella intermedia, 17.9% (7) – Porphyromonas gingivalis and Porhyromonas endodontalis. Aggregatibacter actinomycetemcomitans was isolated only in 5.1% (2) of individuals, Tannerella forsythia – in 2.6% (1). Combinations of 4 microorganisms were detected in 20.5% (8), from 3 - in 12.8% (5), from 2 - 15.4% (6). In 12.8% (5) of the examined patients were not isolated from any of the studied periodontal pathogens. When checking correlations between the level of hygiene and the number of pathogenic microorganisms detected, a moderate direct relationship was established between the value of the OHI-S index and the amount of Fusobacterium nucleatum r=0.36 (p&lt;0.05) and Prevotella intermedia r=0.30 (p&lt;0.05), as well as a moderate direct relationship between the value of the PMA index and the amount of Porphyromonas gingivalis r=0.33 (p&lt;0.05), Porphyromonas endodontalis r=0.31 (p&lt;0.05), Prevotella intermedia r=0.30.Conclusion. In patients with chronic periodontitis of moderate severity, a microbial biofilm is formed on the surface of the periodontium, represented by anaerobic bacteria. In periodontal pockets, the amount of Fusobacterium nucleatum and Prevotella intermedia increases with the deterioration of the hygienic condition of the oral cavty. With the development of inflammation in the gum tissues, periodontal pathogens Porphyromonas gingivalis and Porphyromonas endodontalis are more often detected, having more aggressive invasive and toxic properties in relation to periodontal tissues.

Prevalence of Tooth Resorptive Lesions in 120 Feline Dental Patients in Israel.

Tooth resorption (TR) is a common dental condition seen in domestic cats, with a reported prevalence of 29-37.5% in clinically healthy cats and 60.8-67% in cats presenting for dental problems. Radiological and medical records of 120 cats that underwent dental treatment at a private veterinary clinic in Israel between October 2015 and February 2023 were reviewed. Records in which full-mouth radiographs had been obtained were included in the study. Radiographs were screened for TR according to the AVDC classification. Teeth affected by TR were identified in 79/120 (66%) cats. The mean age of cats with TR and non-TR was 8.3 and 6.2 years, respectively. The median age of the TR and non-TR cat populations was 8 and 7 years, respectively. A correlation was found between the number of teeth affected per cat and the age in TR cats. Cats 10 years of age and older, had a TR prevalence of 83.3%. The teeth most commonly affected by TR (82.3%) were the mandibular fourth premolar teeth (308,408).

Background Characteristics and Cognitive Factors as Determinants of Oral Health in Pregnant Women, Tehran, Iran: A Cross-Sectional Study.

Objectives: Pregnancy can lead to oral health issues, yet many women remain unaware of the potential negative impact on their pregnancy. This study aimed to assess the dental and periodontal health of pregnant women in Tehran, Iran, and identify its associated factors. Materials and Methods: A cross-sectional study was conducted with 221 pregnant women attending 12 randomly selected public health centers in Tehran, Iran. A self-administered questionnaire gathered data on background characteristics, oral health knowledge, and self-reported health. Periodontal status, oral hygiene, and dental health were assessed using bleeding on probing (BOP), simplified oral health (OHI-S), and decayed-missing-filled teeth (DMFT) indices. Statistical analysis included simple and multiple linear regression (P<0.05). Results: The participants' ages ranged from 18 to 42 years (mean: 27.9 years, SD: 5.5). On average, participants scored 4.1 out of 11 (SD: 1.7) for general oral health knowledge and 1.62 out of 4 (SD: 0.9) for knowledge about oral health during pregnancy. The mean DMFT was 8.28 (SD: 5.7), with 65.6% of women having fair oral hygiene according to the OHI-S. Participants reporting poor general health had more debris (B: 0.276, P=0.043), while those with higher general oral health knowledge had fewer missing teeth (B: -0.183, P=0.048). Conclusion: Despite partial free oral health care provided to pregnant women in Iran, the dental and periodontal conditions of the participants were unsatisfactory. Implementing motivational educational programs within the primary health care system could be instrumental in improving the oral health of pregnant mothers.
