Complete Loss of Natural Teeth and Loneliness: A Fixed-Effect Analysis

Psychosocial properties of oral health have been reported. The present study aimed to investigate the causal effect of complete loss of natural teeth on loneliness by using fixed-effects analysis to control for confounding factors, including unmeasured time-invariant factors. Data from older adults participating in at least 2 consecutive waves of the English Longitudinal Study of Ageing in waves 3 (2006/2007), 5 (2010/2011), and 7 (2014/2015) were analyzed (N = 18,682 observations from 7,298 individuals). The association between complete loss of natural teeth and loneliness score (ranging from 3 to 9) was examined using fixed-effect linear regression analysis adjusting for time-varying confounders, including sociodemographic and health characteristics. The prevalence of complete tooth loss was 12.7%, 12.8%, and 10.6% in waves 3, 5, and 7, respectively. Individuals who transitioned to complete tooth loss during any 2 consecutive waves had an increase in loneliness score by 0.27 (95% confidence interval [CI] 0.03, 0.52), which was greater than those who maintained natural teeth (−0.03; 95% CI −0.05, −0.01). Fixed-effects analysis adjusting for time-varying confounders revealed a significant association between complete loss of natural teeth and an increase in loneliness score by 0.31 (95% CI 0.17, 0.46). Complete loss of natural teeth among older adults in England was associated with loneliness, even after accounting for measured time-varying and (un)measured time-invariant confounders. Retaining natural teeth may reduce the risk of loneliness.

Amelogenin-Inspired Autoadaptive Peptide in a Caries Microenvironment Facilitates Long-Term Protection of the Dentin-Pulp Complex.

Dental caries, one of the most prevalent infectious diseases, is the primary contributor to the early loss of natural teeth and is a significant public health issue. Known as the tooth's bioactive core, the dentin-pulp complex (DPCX) comprises tightly connected hard and soft tissues that not only serve as a biological barrier for the inner tooth tissue but also produce reparative dentin following mild disruptions. While efforts to preserve DPCX are numerous, most strategies focus on temporary antibacterial measures, inflammation reduction, or tissue regeneration, lacking a comprehensive, long-lasting solution. In this study, TVH-19, an autoadaptive peptide mimicking the pH- and ion-responsive capacity of amelogenin, was designed to exert multifaceted preservation of DPCX, providing a comprehensive strategy for preserving vital pulp. Leveraging its unique amphiphilicity-related cell penetration and ion/pH-responsive self-assembly properties, TVH-19 outperforms conventional pulp preservation materials by being capable of rapid cell penetration, minimizing diffused side effects, providing environment-responsive self-assembly/disassembly for balanced long-term antibacterial and cell protection, and facilitating the formation of lysosomal-escaping intracellular aggregates for the continuous activation of PDGFRα+ dental pulp stem cells.

Relationship between the number of lost teeth and the occurrence of depressive symptoms in middle-aged adults: a cross-sectional study

BackgroundMany recent studies suggest the existence of a relationship between oral health and the occurrence of depressive symptoms. The aim of this study was to assess the relationship between the number of lost teeth and the occurrence of depressive symptoms in middle-aged adults.MethodsAn analysis was performed on the data obtained from the PONS project (POlish-Norwegian Study), conducted in the Świętokrzyskie Province in Poland in 2010–2011. The research material included the cross-sectional data of 11,901 individuals aged 40–64 years (7967 women). Depressive symptoms, used as outcome variables, were assessed with a questionnaire. The participants provided the responses to questions concerning the occurrence of eight symptoms over the last 12 months. The answers were scored as 1 point or 0 points. The participants were divided into three tercile groups based on their total scores: no or mild (0–2 points), moderate (3–5 points), and severe depressive symptoms (6–8 points). The self-reported number of lost teeth was analysed according to the following categories: 0–4, 5–8, 9–27, and a complete lack of natural teeth. Multivariable logistic regression analysis for depressive symptoms was used in relation to the number of lost teeth. The following covariates were included in the adjusted model: age, sex, place of residence, education, marital status, BMI, diabetes status, stressful life events in the last year, use of antidepressants, smoking, and sugar and sweet consumption.ResultsThe likelihood of both moderate (OR = 1.189; 95%CI: 1.028–1.376; p < .020) and severe (OR = 1.846; 95%CI: 1.488–2.290; p < .001) depressive symptoms showed the strongest relationship with a total lack of natural teeth. A loss of more than 8 natural teeth was also significantly associated (OR = 1.315; 95%CI: 1.075–1.609; p < .008) with the occurrence of severe depressive symptoms.ConclusionsThe loss of natural teeth was positively related to the occurrence of depressive symptoms in middle-aged adults. Thus, there is an urgent need to intensify stomatological prophylaxis, education and treatment for middle-aged individuals.

New measure of functional tooth loss for successful Oral ageing: a cross-sectional study

BackgroundThis cross-sectional study evaluated the impacts of functional tooth loss on oral health-related quality of life (OHRQoL) among elderly people compared with the impacts of several common indicators of oral health. Additionally, the cut-off of functional tooth loss needed for a better OHRQoL was investigated to establish a new measure for successful oral ageing.MethodsData from people aged 65–74 were extracted from the Fourth National Oral Health Survey in Sichuan, China. Functional tooth loss was defined as both natural tooth loss and nonfunctional teeth, such as third molars, residual roots, and removable dentures. The cut-offs of tooth loss were first identified as 12, based on the previous definition of functional dentition (≥20 natural teeth except the third molars), and 14, 16, or 18 for further investigation. OHRQoL was evaluated by the standardized Geriatric Oral Health Assessment Index (sGOHAI) score. Logistic regression was performed to estimate the impacts on OHRQoL. Additionally, subgroup analyses were conducted using the stratified chi-square test to explore the effect of functional tooth loss at each position.ResultsThe mean GOHAI score of the 744 participants was 48.25 ± 7.62. Elderly people who had lost ≤12 functional teeth had greater odds of reporting a higher sGOHAI score than those who had lost more functional teeth (odds ratio (OR) 1.49, 95% confidence interval (CI) 1.05–2.11). No significant difference in the sGOHAI score was detected between people who had lost 13–16 functional teeth and those who had lost ≤12 functional teeth (0.61, 0.35–1.07). The loss of second premolars and first and second molars had great impacts on the sGOHAI score when ≤12 or ≤ 16 functional teeth had been lost.ConclusionsCompared with natural tooth loss, functional dentition and occluding pairs, functional tooth loss can be a better indicator of OHRQoL in the elderly population. Sixteen remaining functional teeth seem to be sufficient to maintain good OHRQoL and successful oral ageing despite that number being previously acknowledged as ≥20 teeth.

Biomedical and Psychosocial determinants of Alzheimer’s disease among elderly living in India

AbstractBackgroundAgeing not only affects physical health but also contributes in decline of mental health of older people. Memory or cognitive ability is an important factor in health and well‐being of older adults. In India, cognition ability among older adults adversely affects many activities of daily living including quality of life. The neurological disease such as Alzheimer (or Dementia) has risen among Indian people age 60 years or above, due to various biomedical risk factors including disease mechanisms. This research has done to understand the psychosocial and biomedical predictors of Alzheimer’s’ disease among older people (60 years or above).MethodThis study has used the data from Longitudinal Ageing Study in India (LASI). LASI is a nationally representative survey on various socioeconomic and health aspects of older adults living in India. LASI (Wave‐1) was done with a sample of 31,902 older people (age 60 years or above). Logistic regression modeling was used to understand the predictors of Alzheimer’s disease among elderly, while multivariate decomposition analysis was used in order to understand the contributing factors of Alzheimer’s illness among poor and non‐poor elderly.ResultAround 3% of elderly (60 years or above) had any neurological illness, while around 1.2% of elderly had Alzheimer’s (or Dementia). The prevalence of Alzheimer’s (or Dementia) was relatively higher among poor elderly, as compared to non‐poor. The prevalence of Alzheimer’s (or Dementia) was found higher among female elderly as compared to males. This study has found Education (years of schooling), activity of daily living (ADL), living arrangements, depression, MPCE quintile, access to health care, pension, self‐rated health and loss of natural teeth, as the predictors of Alzheimer’s’ (or Dementia) disease among elderly living in India.ConclusionAlzheimer’s (or Dementia) disease is a concern among India elderly as it affects overall quality of life. However, focusing on preventable factors (such as health financing, counselling) may help in decreasing the effect of this disease at some extent. Therefore, policy makers in India should consider on all possible risk factors of Alzheimer’s (or Dementia) for well‐being of elderly (especially poor or living alone).

The Relationship between Tooth Loss and Quality of Life Based on OHIP-14

Introduction: The loss of natural teeth, whether replaced with dentures or not, can affect quality of life, particularly oral health-related quality of life. The loss of one or more teeth causes functional impairment that has a very negative impact on quality of life. Severe tooth loss greatly affects a person's quality of life and affects their survival. Methods: This study used a descriptive approach with a cross-sectional design. The 97 samples in this study were taken by accidental sampling method. The research instrument used in this study was the OHIP-14 questionnaire. The research data were then processed and analyzed with the Pearson correlation test. Results: Pearson correlation analysis obtained p (&lt;0.05) which indicates that there is a significant relationship between tooth loss and quality of life related to the oral cavity. Conclusion: Tooth loss is associated with quality of life related to the oral cavity. Therefore, promotive and preventive efforts for oral health need to be improved for better health.

Comparison of Masticatory Efficiency and Patient Satisfaction of Injection-Molded Conventional Complete Dentures and Biofunctional Prosthetic System Dentures: A Parallel Randomized Clinical Trial.

Introduction Complete loss of natural teeth severely compromises the masticatory efficiency of geriatric patients and directly affects their general health. Biofunctional prosthetic system (BPS) has been developed as an alternate method of denture fabrication to match the higher expectations of patients. Studies comparing BPS dentures with injection-molded conventional complete dentures (IM-CCD) are lacking. Our study aimed to compare the masticatory efficiency and patient satisfaction of BPS dentures with IM-CCD. Methods This trial was designed as a randomized, prospective, single-center, double-blindedstudy with two parallel arms (BPS group and IM-CCD group) having an equal allocation (1:1). Completely edentulous patients aged 45-80 who visited our outpatient department between January and August 2018 were screened and enrolled according to our inclusion and exclusion criteria. Random sequence generation was done using an online randomization program. Allocation concealment was done using sequentially labeled opaque envelopes. The participants and the outcome assessors were blinded. A single operator performed all the clinical procedures in both groups under the guidance of the instructor. The age and gender of the patients were recorded for demographic data at baseline. Primary outcomes were assessed six weeks after denture insertion. The number of denture adjustments required during the first six weeks after denture delivery was recorded as the secondary outcome. Masticatory efficiency was evaluated by the volumetric single-sieve method. An abbreviated version of the Oral Health Impact Profile questionnaire for edentulous patients (OHIP-EDENT) was used for patient satisfaction scores. The total OHIP-EDENT score was calculated by adding all the responses to the 19 questions (ranging from 0 to 38). Individual domain scores were calculated by adding the response to all the questions in that domain. All the data obtained were tested for normality using the Kolmogorov-Smirnov test. Data were analyzed using either unpaired Student's T-test or Mann-Whitney U test for normal and non-normal data, respectively. The gender characteristics of the sample were compared usingChi-Square test. Results Two patients in the IM-CCD group and one patient in the BPS group were lost to follow-up. Hence only the secondary outcome data were analyzed for these patients. Primary outcome data of patients who were lost to follow-up were excluded from the analysis. No significant differences (p>0.05) were found between the two groups for age and gender characteristics of the samples. Masticatory efficiency for both peanut and carrot was found to be significantly higher (p<0.05) in the BPS group than in the IM-CCD group. No significant differences (p>0.05) in the mean scores were observed between the two groups for total OHIP-EDENT scores or the individual domain scores. No significant differences (p>0.05) were observed between the groups for the number of denture adjustments done. Conclusion Within the limitations of the trial, it can be concluded that the BPS dentures significantly improved the masticatory efficiency for both hard (carrots) and soft (peanuts) foods compared to the IM-CCD. However, there was no difference between the masticatory-related complaints domain scores between the two dentures. No significant differences were found between BPS dentures and IM-CCD with respect to overall patient satisfaction scores or post-insertion denture adjustments.

АДГЕЗИВНЫЕ СРЕДСТВА ДЛЯ ФИКСАЦИИ ЗУБНЫХ ПРОТЕЗОВ

The loss of natural teeth and, especially, the complete loss of teeth, is an urgent problem of domestic and foreign dentistry, in the solution of which a significant place is given to prosthetics with full removable plate dentures. To improve the fixation and stabilization of complete removable plate dentures, dentists often consider it appropriate to use adhesive agents, the use of which also gives the patient psychological confidence, ensuring the success of orthopedic dental treatment. The purpose of the literature analysis is to summarize and analyze the literature data for the period 2012-2023 on modern adhesive means for fixing complete removable plate prostheses, their composition, main characteristics and properties. The analysis of scientific articles allows us to come to the conclusion that it is advisable for dentists-orthopedists to recommend adhesive agents to their patients and assist them in selecting a fixing agent taking into account individual characteristics, which will improve the quality and effectiveness of dental treatment.

Association between symptoms of severe periodontitis and post-bronchodilator lung function: results from the China pulmonary health study

BackgroundThe association between periodontitis and post-bronchodilator lung function is unclear. We aimed to determine the associations between symptoms of severe periodontitis (SSP) and post-bronchodilator lung function in the Chinese population.MethodsA cross-sectional study (China Pulmonary Health study) was conducted from 2012 to 2015 in a large Chinese nationally representative sample of 49,202 participants aged 20–89 years. Data on demographic characteristics and periodontal symptoms of participants were collected by questionnaire. Participants who had at least one of the two severe symptoms (tooth mobility and natural tooth loss) in the past year were defined to have SSP, which was set as one variable for analyses. Post-bronchodilator lung function data including forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) were collected by spirometry.ResultsThe values of post-FEV1, post-FVC and post-FEV1/FVC of the participants with SSP were all significantly lower than the participants without SSP (all p < 0.001). SSP were significantly associated with post-FEV1/FVC < 0.7 (p < 0.001). In the multiple regression analyses, SSP were still negatively associated with post-FEV1(b = -0.04, 95%CI (-0.05 -0.03), p < 0.001), post-FEV1/FVC (b = -0.45, 95%CI (-0.63, -0.28), p < 0.001) and significantly associated with post-FEV1/FVC < 0.7 (OR = 1.08, 95%CI 1.01—1.16, p = 0.03) after full adjustment for potential confounders.ConclusionsOur data suggest that SSP were negatively associated with post-bronchodilator lung function in the Chinese population. Longitudinal cohort studies are needed to confirm these associations in the future.

Effects of acrylic dentures on oral mucosa and salivary antimicrobial peptide content in denture wearers

Relevance. Aging of the body leads to the development of an imbalance in the secretory immunity of the oral mucosa, with the loss of natural teeth leading to an even more rapid decline in the host’s oral defense reactions. However, studies on salivary antimicrobial peptides in denture users and their potential role in protecting against the development of inflammation are still scarce at this time.Purpose. To evaluate the effects of full removable acrylic dentures on the oral mucosa and analyze the content of antimicrobial peptides in the saliva of wearers of such dentures.Materials and methods. Sixty-seven (21 men and 46 women) elderly patients (61 to 74 years old) with complete tooth loss were examined and divided into 3 study groups. In the 1st control group the patients did not use any dentures. Patients in groups 2 and 3 were made full removable acrylic dentures for the upper and lower jaws, and in group 2 from the first day of the adaptation period was used domestic denture fixation cream ASEPTA PARODONTAL. Assessment of the denture bed on the hard palate was performed visually using the Schiller – Pisarev test. Microbiological examination for Candida albicans was performed by PCR-diagnostics. The content of antimicrobial peptides in saliva was assessed using ELISA kits by Hycult Biotech.Results. The use of the adhesive cream was found to improve the condition of the palatal mucosa by 25% on the 15th day and by 50% on the 30th day of the adaptation period. Candida albicans was detected in oral material in more than 55% of patients in all groups during their initial examination. In the group of patients using denture fixation cream, a significant decrease in Candida albicans carriage was noted, while an increase in Candida albicans detection of up to 70% was noted in those not using the cream. There was also an increase in the level of cathelicidin LL-37 in the saliva of patients without the use of the cream and with a marked increase in inflammation. One month after dentures in patients without cream use the content of alpha-defensins (HNP 1-3) was significantly lower than that of the group with cream and the control group.Conclusion. On the basis of the carried out clinical and laboratory study, the domestic ACEPTA adhesive cream should be recommended for optimization of the adaptation period to removable acrylic dentures as well as for their permanent use.

Functional Dentition, Chronic Periodontal Disease and Frailty in Older Adults—A Narrative Review

The likelihood of experiencing the impact of chronic disease rises with age, and cumulative functional deficits over time increase the risk of frailty in older adults. The exact causes of frailty are not clear, and research is needed to identify appropriate intervention measures to reduce risk of developing frailty in old age. To review the evidence on the relationship between frailty, dental status and chronic periodontitis and to determine if improvements in oral health of older adults can contribute to reversal of frailty. The oral cavity is the entry point to the gastro-intestinal tract, and natural teeth facilitate efficient mastication of food prior to swallowing and subsequent digestion. The loss of natural teeth, which is gradual and cumulative over the life course, is associated with diminished nutritional intake, especially in older adults. Furthermore, chronic periodontitis has been postulated as a risk factor for frailty. The evidence supporting a strong relationship between oral health status and frailty is not clearcut. Cross sectional studies suggest an association with missing teeth and chronic periodontal inflammation. However, there are very few longitudinal studies and accordingly, it is not currently possible to claim a causal relationship. As yet, there is no evidence to suggest that improvements in oral health contribute to reversal of frailty. Longitudinal studies with robust designs are required to better inform the relationship across functional dentition, chronic periodontitis and frailty in older adults.

Changes in the oral microbioty with losing teeth

BACKGROUND: The influence of the presence/absence of teeth and periodontium preserved at their existence as a balance factor in the oral cavity including the local immunity of the mucous membranes is practically not reported in the literature.&#x0D; AIM: The study aimed to examine the microbial community of the oral cavity at the loss of natural teeth.&#x0D; MATERIAL AND METHODS: Forty-five individuals aged 6174 years were under observation and divided into three study groups. The control group had partial loss of natural teeth. Group 2 had partial loss of teeth on both jaws and suffered from severe chronic generalized periodontitis. Group 3 had partial tooth loss on both jaws and suffered from chronic periapical inflammatory processes (chronic granulomatous periodontitis) in the absence of acute, chronic, or exacerbation of the chronic inflammatory process in periodontal tissues. In this study group, all upper and lower jaw teeth were extracted for oral sanitation before orthodontic treatment. The microbiota was assessed before surgical sanitation of the oral cavity (before tooth extraction) and 3035 days after the last tooth extraction, i.e., at complete tooth loss on the upper and lower jaws.&#x0D; RESULTS: On initial examination, the detection frequency of five red complex periodontopathogens (Prevotella intermedia, Bacteroides forsythus, Treponema denticola, Actinobacillus actinomycetemcomitans, and Porphyromonas gingivalis) ranged from 27% to 53%, which was significantly higher than that of the control group (13%27%). In 1 month after complete tooth extraction, the detection of these microorganisms in the experimental groups (with periodontitis and periodontitis) reliably decreased (P. intermedia, 20%; B. forsythus, 20%; T. denticola, 20%; A. actinomycetemcomitans, 20%; P. gingivalis, 33%), which was not significantly different from that of the control group.&#x0D; CONCLUSION: Complete extraction of teeth did not affect the presence of Staphylococcus spp. and Streptococcus spp. in the saliva of patients with periodontal diseases but led to a significant reduction in the presence of periodontopathogens and Candida sp. in the saliva of older people.

Changes in mucosal immunity of oral cavity upon tooth loss in patients with periodontal diseases

Partial or complete loss of teeth occurs in elderly and senile people, caused, mainly, by chronic generalized periodontitis. At the same time, the impact of presence or absence of persisting teeth and periodontium, is practically not covered in the literature as a factor of balance in the oral cavity, including local immunity of the mucous membranes. Our work concerned the changes in local immunity of the oral cavity occuring with the loss of natural teeth. We have observed 45 elderly people who were divided into 3 study groups, i.e., without inflammatory periodontal pathology (1), with periodontitis (2) and with chronic periapical inflammatory processes in the absence of periodontal inflammation (3). In order to sanitize oral cavity before the upcoming dental prosthetics, the patients of study groups 2 and 3 underwent extraction of all teeth in the upper and lower jaws. Indices of local immunity of the oral cavity in the salivary fluid of patients were assessed before surgical sanitation of the oral cavity (before the teeth extraction) and 30-35 days after removal of the last tooth. We have measured the salivary levels of secretory immunoglobulin A (sIgA) as well as pro-inflammatory cytokines, i.e., interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor- (TNF), and anti-inflammatory cytokines, e.g., receptor antagonist of interleukin-1 (RAIL), interleukin-4 (IL-4), interleukin-10 (IL-10)), as well as contents of antimicrobial peptides in saliva (catelicidin LL-37 and alphadefensins 1-3 (HNP1-3). We have found that the development of inflammation in severe inflammatory periodontal diseases, in particular, chronic generalized periodontitis requiring tooth extraction for oral cavity sanitation is characterized by functional insufficiency of secretory immunity of the oral mucosa associated with decreased secretion of secretory immunoglobulin A and antimicrobial peptides of neutrophilic origin, as well as a shift in the salivary cytokine balance towards increased production of pro-inflammatory cytokines. Removal of teeth, as the main source of inflammation and the basis for maintenance of dysbiotic microbiome biofilm leads to elimination of inflammation and the restoration of immune balance in the oral cavity.

SOCIAL DETERMINANTS OF ORAL HEALTH AMONG OLDER ADULTS: RURALITY MATTERS

Abstract Oral health is often viewed as a predictor of emotional well-being. Older age and any tobacco use are among the strongest predictors of poor oral health. We sought to examine the roles of age, tobacco use, and dental health in relation to emotional well-being. Moreover, we identified unique predictors of oral health. Data were provided by 197,786 adults completing the 2020 BRFSS (mean age = 54.3 yrs; 46% men; 80% white; 15% rural; 41% had ever regularly used tobacco). Although 53.6% reported no loss of natural teeth, 29.5% reported losing between 1 and 5 teeth and 17% reported having lost 6 or more natural teeth. Hierarchical linear regression analyses revealed that younger adults, smokers, urban-dwellers, and those with more tooth loss experienced more poor mental health days, F (4, 359016) = 4307.6, p &amp;lt; .001, R^2= .05. Tooth loss uniquely contributed to the variance explained, above and beyond the other predictors (Step 2: F (1, 359016) = 3722.01, p, .001). We also conducted a multinomial logistic regression to test whether age, tobacco use, and rurality could differentiate among levels of tooth loss. These equations were significant, with odds ratios showing that rurality was the strongest predictor of tooth loss. Our results suggest that rurality is a strong predictor of oral health, even beyond the influence of age and tobacco use. Future interventions used to improve the oral health of people, including older adults, must consider the greater needs present to rural-dwelling Americans

Oral symptoms and oral hygiene behaviours among patients with type 2 diabetes at a hospital in Japan: A cross-sectional study.

Effective daily oral hygiene behaviour will prevent periodontal disease. This study aimed to examine the oral symptoms, oral hygiene behaviours and factors contributing to oral hygiene behaviours among patients with type 2 diabetes in a hospital in Japan. A cross-sectional survey was conducted with 198 patients with type 2 diabetes. Oral symptoms were assessed using a dichotomous scale based on clinical guidelines. Oral hygiene behaviours were assessed based on the frequency of daily tooth brushing and the use of interdental cleaning aids. Chi-square tests and logistic regression analyses were also performed. Overall, 71.2% of the participants had oral symptoms. Of the participants, 80.3% performed twice daily tooth brushing and 61.1% did not perform interdental cleaning on a daily basis. Logistic regression analysis revealed that tooth brushing behaviour was negatively associated with male patients (odds ratio [OR]=0.45, 95% confidence interval [CI]: 0.25-0.80), difficulty with mastication (OR=0.63, CI: 0.43-0.92) and tooth loss (OR=0.68, CI: 0.46-1.00) and positively associated with periodontal disease (OR=1.73, CI: 1.10-2.72). There were no significant variables related to the use of interdental cleaning aids. Patients need to learn about the necessity for regular oral hygiene behaviours and the appropriate way. In particular, support for male patients, those who have difficulty with mastication, those who have experienced natural tooth loss, and those who have not been diagnosed with periodontal disease are needed.

Estudio de los factores que afectan la salud oral en una muestra de las encuestas NHANES en los Estados Unidos

Oral health problems include dental caries, gum diseases, loss of natural teeth, and other mucosal diseases. The present research aimed to study the factors affecting periodon-tal health in the residents of the United States of America. This study examined if there were significant differences in the health of teeth and gums with respect to last visit to the dentist, intake of fluoride drops or tablets, gender, and educational level. 493The Study of Factors Affecting Oral Health in a Sample from Nhanes Survey in the United StatesParneet Sihota,Helda Pinzon- PerezVol. 38 (2) 2022 - 491-504Barranquilla (Col.) Materials &amp; Methods: The study analyzed secondary data from the National Health and Nutrition Examination Survey 2017-18. This study examined a population of 9,254 resi-dents aged 1 and older. The Chi-Square Test of Independence was used to test significance among the variables of last visit to the dentist, received fluoride drops or tablets, gender, and educational level. Results: The study found no statistically significant differences in health of teeth and gums with respect to intake of fluoride drops or tablets, gender, and educational level. However, the study did find a statistically significant difference in the health of teeth and gums with regard to the last visit to the dentist among residents of the US. Individuals who have visi-ted the dentist in the last six months have rated their health of teeth and gums as excellent as compared to those who did not visit the dentist in the last six months.Conclusions: Future studies should review other factors affecting oral health such as high sugar intake, diabetes, chronic diseases, and genetics. Emphasis should be given to the identification of inequities associated with periodontal health among various cultural and ethnic groups in the United States of America.

PRESERVATION OF RESIDUAL ALVEOLAR RIDGE USING TOOTH SUPPORTED OVERDENTURE PROSTHESIS- A CASE REPORT

Loss of alveolar bone is a great entity to be worried about after loss of natural teeth. Overdenture is a treatment modality in means of alveolar bone preservation retention and stability of prosthesis by preserving the roots of the remaining teeth thereby increase the patients perception, acceptance and quality of life. It is the most commonly treatment modality for elderly patient with two or more teeth remaining in the either arch. The use of copings and precision attachments on the remaining teeth enhances the retention of the denture. Dentists have a responsibility to prevent tooth loss whenever possible and everything should be done to keep the patient away from an edentulous state. Preventive prosthodontics emphasizes upon the importance of procedures that can delay or rectify the future problems in prosthesis and the overdentures are the optimum method to achieve this requirement. In this present case report described the rehabilitation of a patient with few natural teeth present using tooth supported overdenture which restored the function and evades the social stigma, thereby improving the quality of life of the patient.

Comparative evaluation of the relationship of teeth color and soft tissue color of the face in individuals with natural dentition

Introduction The aim of this study is to make it easier for dentists to choose artificial tooth color in fully and partially edentulous patients by evaluating the relationship between the color of the soft tissues of the face and the color of the teeth. Methodology The CIEL*a*b* color values of the maxillary central teeth of the volunteers participating in the study were measured by spectrophotometer, and skin, lip and eye color were measured from facial images containing ceramic blocks to standardize the light and color values using Adobe Photoshop software. The Kolmogorov-Smirnow test and Spearman Rank Correlation test were used to evaluate the data. Results It was observed that there was a higher correlation between the L* values of the teeth and the L* and b* values of the skin.When the analysis between the color measurements taken from the lip photographs and the teeth was examined, it was seen that there was a statistically significant positive correlation between the L* values of the upper central teeth and the a* values of the lip. Conclusion The results showed that the CIEL*a*b* parameters of skin color and lip color can be used in the selection of tooth color in case of loss of natural teeth or discoloration of existing teeth

Role of Bone Grafts in Implant Surgery: A Review

Introduction of dental implants and more concern in patients about esthetics after loss of natural teeth increases the demand of bone grafts. Various types of bone grafts as allografts, xenografts and autografts are used all with their own pros and cons. Bone grafts are more likely to succeed when the conditions at the recipient site are favourable and certain requirements are fulfilled. This review explores the use of various bone grafts in implant dentistry.
