Prevalence of root stumps of primary teeth in paediatric patients

The purpose of this study is to find negligence of early dental treatment. This research fulfils by providing insight on parents' care towards the child. The aim of our study is to find the prevalence of root stumps of primary teeth in pediatric patients. The current study was a comparative, descriptive and retrospective study which was performed under a university setting where all the data of patients with root stumps of primary teeth were collected by reviewing patients records and analysed the data of 86000 patients between June 2019 to March 2020. The collected data were tabulated; statistical analysis was done by SPSS – IBM. The study showed that out of 2360 extractions, 35 (1.5%)was found to be root stumps of primary teeth. The root stumps were more prevalent among four years of age (42.86%) with female predilection (81.25%) and the higher incidence with maxillary 2nd molars (11.4%). The prevalence of tooth loss was found to be high in children as well as the adults so dental professionals should utilize the various measures and protocols available in preventive dentistry to minimise the effects of tooth loss.

Early-life course factors and oral health among young Norwegian adults.

Using a national sample of young Norwegian adults, we examined whether unpleasant experience with dental care during childhood is associated with tooth loss and oral health-related quality of life in adulthood after accounting for early- and later-life socio-behavioural circumstances and dental avoidance behaviour. 2433 individuals aged 25-35years participated in an electronic survey. Oral quality of life was measured using the oral impact of daily performance (OIDP) inventory. Generalized linear models and negative binomial regression models were used to estimate the association of early unpleasant experiences with dental care and tooth loss and OIDP scores. Incidence rate ratio (IRR) and 95% confidence intervals (CI) were used to estimate the relative differences in prevalence of tooth loss and OIDP scores. Adjusting for early-life characteristics only, the prevalence of tooth loss was 1.42 (IRR=1.42, 95% CI: 1.24-1.64) and 1.96 (IRR=1.96, 95% CI: 1.70-2.26) times higher among individuals who reported unpleasant experiences a few times or several times, than in individuals who did not report unpleasant experiences with dental care in childhood. Adjusting further for educational level, smoking and tooth brushing attenuated the relative differences (IRR=1.40, 95% CI: 1.22-1.62 and IRR=1.88, 95% CI: 1.62-2.17, respectively). Lastly, when adjusting for dental avoidance behaviour, the prevalence of tooth loss was 1.29 (IRR=1.29, 95% CI: 1.11-1.50) and 1.58 (IRR=1.58, 95% CI: 1.32-1.88) times higher among individuals who reported unpleasant experiences a few times or several times than in those who did not. Corresponding associations of early unpleasant experience with OIDP were (IRR=1.41 95% CI: 1.22-1.63) and (IRR=1.69, 95% CI: 1.42-2.01) when adjusting for early-life characteristics, and (IRR=1.39, 95% CI: 1.20-1.60) and (IRR=1.51, 95% CI: 1.27-1.80) when adjusting for education, smoking and tooth brushing. When adjusting for dental avoidance behaviour, the association of early unpleasant experience with OIDP became nonsignificant. Unpleasant dental care experiences during childhood are associated with poor oral health in adulthood, independent of later-life socio-behavioural characteristics including negative dental care seeking. This highlights the importance of tailoring regular contacts with dental healthcare services in childhood to build confidence in children and thus has implications for healthcare policy.

Influences of behaviour and attitude on education related inequality in tooth loss: findings from Norway and Sweden over 5 years of follow- up

Objectives Following community dwelling cohorts in Norway and Sweden from 65 to 70 years, this study aimed to answer the following questions; Is there cross country variation in educational inequality in tooth loss between the Norwegian and Swedish cohorts? Does oral health behaviours and attitudinal beliefs play a role in explaining educational inequality in tooth loss across time and cohorts? Material and Methods In 2007 and 2012 Statistics Norway administered mailed questionnaires to all individuals born in 1942 in three counties. The response rate was 58% (n = 4211) in 2007 and 54.5% (n = 3733) in 2012. In Sweden the same questionnaires were sent to the 1942 cohort in two counties. The final response rate in 2007 and 2012 were respectively, 73.1% (n = 6078) and 72.2% (n = 5697). Results In Norway, tooth loss prevalence was 21.8% in 2007 and 23.2% in 2012. Corresponding figures in Sweden were 25.9% and 27.3%. The prevalence of tooth loss was higher among lower than higher educated participants and the gradient was significantly weaker in Sweden than in Norway. Multiple variable analyses adjusting for oral behavioural and attitudinal variables attenuated education related gradients in both cohorts. Conclusion Education related inequality in tooth loss was stronger in the Norwegian than in the Swedish cohort across the survey years. Oral behaviours and attitudinal beliefs played a role in explaining the gradients across time. This illustrates a necessity to promote oral health enhancing behaviours and attitudinal beliefs, particularly so in lower educational groups.

School academic climate and oral health (tooth loss) in adolescents.

BackgroundPreventing tooth loss depends on oral health maintenance behaviors. This study hypothesized that adolescents with educational aspirations have greater motivation to invest in the future, including maintenance of oral health status.AimTo analyze the association between a school academic climate of educational aspirations and tooth loss (first permanent molars) among adolescents.MethodsA cross-sectional study was designed to include 2,500 adolescents (aged 14–19 years) enrolled in public high schools of Olinda located in Northeast Brazil. Multilevel Poisson regression random intercept models were conducted with tooth loss (first permanent molars) as the outcome. The primary cohort of interest was school academic climate, as measured by the proportion of students taking the national high school exams.ResultsTooth loss of the first permanent molars (assessed by clinical exam) was more prevalent in adolescents from more disadvantaged backgrounds (receiving family allowance, low maternal education). However, after controlling for a wide range of individual characteristics, adolescents enrolled in schools with lower academic climate had a higher prevalence of tooth loss (PR 1.42, 95%CI: 1.09,1.85).ConclusionThe school academic climate is associated with tooth loss, suggesting that educational aspirations are linked to adolescent oral health maintenance behaviors.

A STUDY ON ASSOCIATION 0F TOOTH LOSS & PERIODONTAL DISEASE IN PATIENTS SUFFERING FROM DIABETES FROM BIHAR REGION

Diabetes is one of the common diseases of modern times and one of the most common systemic disorder that is connected to periodontal disease. Periodontal diseases are bacterially induced chronic inflammatory diseases affecting the tissues surrounding and supporting the teeth. The lesion begins as gingivitis, an inflammation of the gingival tissues only, and may progress to periodontitis, where destruction of connective tissue attachment and alveolar bone can eventually lead to tooth loss. Hence based on above reported findings the present study was planned for study of prevalence of tooth Loss in Patients Suffering from Diabetes from Bihar Region.
 The present study was planned in Department of Dentistry, Anugrah Narayan Magadh Medical College and Hospital, Gaya, Bihar. Total 100 cases were enrolled in the present study. In the enrolled patients 50 cases were Diabetic and 50 were non-diabetic cases.
 The data generated from the present study concludes that periodontal disease increases in diabetes group than in control group. Thus, a diabetic patient should always see that he/she maintains his/her oral hygiene by following proper tooth brushing habits. Diabetics should take care to see that they get their teeth restored as early as possible, if decayed. They should follow the instructions given by the physician or the dietician for the intake of non-cariogenic diet. The prevention of periodontal breakdown in diabetic patients is mostly based on the education of the individual. Thus, patients should be informed about the importance of oral health for diabetics, and they should be taught that the main symptom of periodontal disease is gingival bleeding.

Understanding the association between self-reported poor oral health and exposure to adverse childhood experiences: a retrospective study

BackgroundAdverse childhood experiences, including physical, sexual or emotional abuse, can have detrimental impacts on child and adult health. However, little research has explored the impact that such early life experiences have on oral health. This study examines whether experiencing adverse childhood experiences before the age of 18 years is associated with self-reported poor dental health in later life.MethodsUsing stratified random probability sampling, a household survey (N = 5307; age range 18–69 years) was conducted in the South of England (Hertfordshire, Luton and Northamptonshire). Data were collected at participants’ homes using face-to-face interviews. Measures included exposure to nine adverse childhood experiences, and two dental outcomes: tooth loss (> 8 teeth lost due to dental caries or damage) and missing or filled teeth (direct or indirect restorations; > 12 missing or filled teeth).ResultsStrong associations were found between exposure to childhood adversity and poor dental health. The prevalence of tooth loss was significantly higher (8.3%) in those with 4+ adverse childhood experiences compared to those who had experienced none (5.0%; p < 0.05). A similar relationship was found for levels of missing or filled teeth (13.4%, 4+ adverse childhood experiences; 8.1%, none; p < 0.001). Exposure to 4+ adverse childhood experiences was associated with a higher level of tooth loss and restorations at any age, compared to individuals who had not experienced adversity. Demographically adjusted means for tooth loss increased with adverse childhood experience count in all age groups, rising from 1.0% (18–29 years) and 13.0% (60–69 years) in those with none, to 3.0% and 26.0%, respectively in those reporting 4+.ConclusionsExposure to childhood adversity could be an important predictive factor for poor dental health. As oral health is an important part of a child’s overall health status, approaches that seek to improve dental health across the life-course should start with safe and nurturing childhoods free from abuse and neglect. Given the growing role that dental professionals have in identifying violence and abuse, it seems appropriate to raise awareness in the field of dentistry of the potential for individuals to have suffered adverse childhood experiences, and the mechanisms linking childhood adversity to poor dental health.

Prevalence of Dental Caries and Missing teeth among the Women of Reproductive age

Dental caries is a common global health problem today. There is a sharp increase in the prevalence of tooth loss following dental caries globally. The prevalence of tooth loss and dental caries was observed to be higher in women than in men in many parts of the world. Changing hormonal levels plays a vital role in causing oral diseases and in turn oral diseases may affect fertilization among women in reproductive age. This study aimed to determine the prevalence of dental caries and missing teeth among women of reproductive age. A retrospective study was conducted using records of patients visited University dental hospital. A total of 312 consecutive case records of patient age ranging from 18-40 years were retrieved. Data on the number of “D” component and the number of ‘M’ component of Decayed, Missing and Filled teeth Index (DMFT) and Decayed, Missing and Filled surface Index (DMFS) were entered and subjected to statistical analysis. Descriptive statistics and chi-square association test was employed to find the association. The prevalence of dental caries and missing teeth was more in the age group 26-40years. Among the age group of 26-40 years, 42.31% of women had 0-5 decayed teeth, 37.82% of the women had 0-5 missing teeth, 25.64% of the women had 0-5 decayed surfaces, and 37.5% of the women had 0-5 missing surfaces. No significant association was present between reproductive age and decayed teeth, missing teeth surface (p>0.05), whereas a significant association of reproductive age with number of missing teeth and decayed teeth surface was observed (p

Tooth loss, prosthetic status, and prosthodontic treatment needs of an Indian fishing community

Background: The disadvantaged communities are often susceptible to poor oral health due to low incomes, lack of awareness, and low health-care utilization. Untreated dental diseases can lead to loss of teeth which may result in unmet prosthodontic needs. The present study assessed tooth loss, prosthetic status, and treatment needs of a fishing community in Mangalore, India. Materials and Methods: Oral examination of 400 individuals from a fishing community was done through a house-to-house cross-sectional survey using the World Health Organization oral health assessment form 1997. Data on demography, personal habits, and dental utilization were collected using a questionnaire. Results: The prevalence of tooth loss was 43%, and the mean number of missing teeth was 2.32 ± 5.21. More tooth loss was observed in older age groups and smokers. About 97% of the participants did not use any prosthesis, whereas it was needed in 23% in the maxillary arch and 33% in the mandibular arch. Prosthetic need was higher in older age groups. Majority of the participants had never visited a dentist before. Conclusions: Tooth loss was associated with age and smoking in this population. Utilization of oral health services was low, and prosthetic need was high. Targeted health promotion is recommended to prevent tooth loss and improve prosthetic status.

Association between central obesity and tooth loss in the non-obese people: Results from the continuous National Health and Nutrition Examination Survey (NHANES) 1999-2012.

This study was to investigate the association between central obesity and tooth loss in non-obese population. This national cross-sectional study included 19436 participants, aged 19-74years with body mass index(BMI) 18.5-29.9kg/m2 , from the National Health and Nutrition Examination Survey(NHANES) 1999-2012. Tooth loss was measured by the number of teeth missing. Central obesity was defined by a categorized 3-level waist circumference according to the WHO recommendation. A zero-inflated negative binomial model was used to investigate the association between tooth loss and central obesity. All models were adjusted for demographic, socioeconomic status, lifestyles, medical conditions and inflammatory biomarkers. For an overweight person with central obesity, the prevalence of tooth loss increased by 31% (Prevalence ratio [PR]: 1.31, 95% CI: 1.20-1.44) compared with a person with similar BMI but no central obesity, and increased by 40% (PR: 1.40, 95% CI: 1.26-1.56) if compared with a normal-weight person without central obesity. There was a clear stepwise association between tooth loss and central obesity. The results reveal that central obesity is significantly associated with tooth loss in the non-obese population, which suggests that non-obese individuals with central obesity may represent an important target population for oral health preventive strategies.

Changes in Older Adults' Oral Health and Disparities: 1999 to 2004 and 2011 to 2016.

To examine changes in tooth loss and untreated tooth decay among older low-income and higher-income US adults and whether disparities have persisted. Sequential cross-sectional study using nationally representative data. The 1999 to 2004 and 2011 to 2016 National Health and Nutrition Examination Survey. Noninstitutionalized US adults, aged 65 years and older (N = 3539 for 1999-2004, and N = 3514 for 2011-2016). Differences in prevalence of tooth loss (having 19 teeth or fewer, 8 teeth or fewer, and no teeth) and untreated decay and mean number of decayed and missing teeth (DMT) between low- and high-income adults 65 years and older in each survey and changes between surveys. Adjusted prevalence and count outcomes were estimated with logistic and negative binomial regression models, respectively. Models controlled for sociodemographic characteristics and smoking status. Reported findings are significant at P < .05. In 2011 to 2016, unadjusted prevalence of having 19 teeth or fewer, 8 teeth or fewer, no teeth, and untreated decay among low-income adults 65 years and older was 50.6%, 42.0%, 28.6%, and 28.6%, respectively. Multivariate analyses indicated that although most tooth loss measures improved between surveys for both income groups, tooth loss among low-income adults remained at almost twice that among higher-income adults. The disparity in untreated decay prevalence in 2011 to 2016, 15.2 percentage points (26.1% vs 10.9% for low vs high income) was twice that in 1999 to 2004, 8.5 percentage points (22.9% vs 14.4% for low vs high income). DMT decreased for both groups, with lower-income adults having about five more affected teeth in both surveys. Tooth loss is decreasing, but differential access to restorative care by income appears to have increased.

Prevalence, Causes and Pattern of Tooth Loss among Elderly People in Port Harcourt, Nigeria

Tooth loss constitutes a condition of public health interest and can be used as a measure of the oral health of a population. The study was undertaken to determine the prevalence, pattern and causes of tooth loss among the elderly in Port Harcourt, Nigeria. The study was an observational research design carried out using pensioners 60 years and above. Subjects were selected by systematic random sampling and data was collected by the use of questionnaire and clinical oral examination. Collected data was analyzed using SPSS version 20. No case of complete edentulousness was recorded in this study. The prevalence of tooth loss was 43.6%. Although the prevalence was higher in males than in females and older than younger age group, the difference was not significant. The mean tooth loss was 8.9±2.1. Tooth loss was higher in the maxillary anterior segment (14.2%) than the mandibular anterior segment (13.3%) and in the mandibular posterior segments (38.8%) than the maxillary posterior segments (33.7%). These differences were however not significant. Periodontal disease accounted for 50.3% (2435) of the tooth loss, dental caries and trauma accounted for 44.2% (2142) and 5.5% (264) of tooth loss respectively. The prevalence of tooth loss was high among the study population. Periodontal disease and dental caries were the main cause of tooth loss in this group. Therefore, there is need to educate and promote oral health among the populace geared towards improving oral hygiene and change in dietary pattern.

Comparative study of risk indicators associated with tooth loss among adult population in urban and rural areas of Muradnagar, Ghaziabad, Uttar Pradesh, India.

Background:Oral health objectives prescribed by World Health Organization for the year 2020 have expressed that there ought to be an expansion in the quantity of people with functional dentitions (at least 21 common teeth) at ages of 35–44 and 65–74 years.Aim:The aim of this study is to examine the prevalence of tooth loss and to evaluate and compare the risk indicators associated with tooth loss among adult population in urban and rural areas of Muradnagar, Ghaziabad.Materials and Methods:A cross-sectional study was led among 1200 adults aged 35–74 years in urban and rural areas of Muradnagar, India. Information was assembled by an interview followed by clinical examination (number of missing teeth). Demographic and socioeconomic factors and self-perceived oral health were the independent variables assessed. One-way analysis of variance, post-hoc test (Bonferroni), Chi-square test, Student's t-test, and logistic regression analysis were used for statistical analysis.Results:Low educational status, no dental check-ups, low frequency of brushing, older age, and smoking habit were independent risk factors for tooth loss. The odds of tooth loss in older adults and illiterates were higher; the odds for tooth loss among those who expressed their desire for replacement of missing teeth were 1.3 times lower than their counterparts.Conclusion:The experiences gained up showed that tooth loss was very pervasive in Muradnagar populace and the critical hazard indicators identified were age, education, socioeconomic status, and cigarette smoking.

Tooth Loss And Mobility In Aggressive Periodontitis Patients: A Retrospective Study

Introduction: Tooth loss has much negative implication in aesthetics and oral function of an individual. Aggressive periodontitis has been known to result in rapid tissue and bone destruction and if left untreated eventually tooth loss. Hence, this study was conducted to assess the prevalence of tooth loss and tooth mobility in a group of aggressive periodontitis patients. Materials and Methods: This was a retrospective data of aggressive periodontitis patients attending IIUM Dental Clinic that has been diagnosed in year 2014 up to June 2017. The data was extracted from patients’ case records systematically using data extraction forms representing all specific objectives. IBM SPSS-24 was used for data analysis. Results: The prevalence of aggressive periodontitis patients attending IIUM dental clinic within 4 years was 4.2%. Out of this 45.5% presented with tooth loss. Most of them had being diagnosed as generalized aggressive periodontitis and showed to have high mean plaque and bleeding score compared to aggressive periodontitis with no tooth loss. However it was statistically insignificant difference (p&lt;0.05). The tooth loss group also presented with more remaining teeth with mobility. Conclusion: Tooth loss was prevalence in aggressive periodontitis patients. Moreover, remaining teeth were also affected by some degree of mobility, which may affect the normal oral cavity functions and aesthetic. Further study with bigger sample size should be conducted to analyze the impact of the high tooth loss to the patients’ oral and general well-being.

Do Socioeconomic Conditions Explain Ethnic Inequalities in Tooth Loss among US Adults?

To assess whether there are ethnic differences in tooth loss among adult Americans aged <40 years and whether socioeconomic position attenuates these differences if they exist. Data were from the 2014 Behavioral Risk Factor Surveillance System, a health-related telephone cross-sectional survey of a nationally representative sample of US adults. Tooth loss (one tooth or more) was used as the outcome variable. Ethnicity was the main explanatory variable. Family income, education and health insurance were also used in the analysis. Logistic regression models for tooth loss were constructed adjusting for demographic (age, sex, and ethnicity), socioeconomic indicators (income and education), health insurance, dental visits, smoking and diabetes. A total of 76,273 participants were included in the analysis. The prevalence of tooth loss was highest among Blacks (33.7%). Hispanics and other ethnic groups had a higher prevalence of tooth loss than Whites, 29.1% (95%CI: 27.7-30.6), 22.0% (95%CI: 20.3-23.8), and 20.8% (95%CI: 20.2-21.4), respectively. Blacks had odds ratios (OR) 1.98 (95%CI: 1.81-2.16) for tooth loss compared with Whites. After adjusting for socioeconomic positions (SEP), the relationship attenuated but remained significant with OR 1.71 (95%CI: 1.55-1.90). Despite recent changes in the health care system in the United States, ethnic inequalities in tooth loss still exist. Income and education partially explained ethnic differences in tooth loss among Americans aged <40 years.

Aging of the normal occlusion.

The aim of this study was to evaluate the qualitative occlusal changes in individuals with normal occlusion during a period of 47 years. The sample comprised dental models of 20 subjects with normal occlusion (8 males; 12 females) taken at 13.2 years (T1) and 60.9 years of age (T2). The occlusal features were evaluated with the objective grading system (OGS) and with the six keys to normal occlusion (SKNO). The subjects also answered a questionnaire on the aesthetic and occlusal self-perception at T2. Comparisons from T1 to T2 were performed with paired t- and McNemar tests (P less than 0.05). OGS analysis showed a significant improvement in the marginal ridge levelling and tooth buccolingual inclination. There was a significant deterioration of the antero-posterior occlusal relationship from T1 to T2. Subjects without tooth loss showed a dental alignment worsening between time points. The marginal ridges, buccolingual inclination, and interproximal contacts improved. The SKNO analysis showed a significant deterioration of the maxillary second molars buccolingual inclination and an improvement of the maxillary second molar angulation. All patients were satisfied with their smiles, and 60 per cent of the subjects had no complaints. Dental crowding caused dissatisfaction in 35 per cent of the sample. A limitation of this study was the high prevalence of tooth loss in the sample from T1 to T2. Only 30 per cent of the subjects had no tooth loss in T2. The aging process slightly deteriorates some occlusal features of individuals with normal occlusion. However, most individuals were satisfied with their aesthetics and occlusal comfort at the sixth decade of life.

Tooth loss and associated factors in adolescents – impact of extractions for orthodontic reason.

Aim: To investigate tooth loss and its determinants in adolescents, considering the effect of extractions due to orthodontics reasons. Methods: This cross-sectional study was performed in students from public and private schools aged 15-19 years old from Passo Fundo, Brazil. The proportional randomly chosen sample included 736 adolescents. Clinical examinations and interviews were performed. Associations between prevalence of tooth loss and exposure variables studied were analysed by Poisson Regression with uni- and multivariate robust variance in two models. One model comprised students who had experienced tooth loss without orthodontic reasons and the other with all of the subjects presenting tooth loss. Results: Prevalence of tooth loss was 21.1% (mean of 0.42). Higher chances for tooth loss were found in the following features: non-whites (PR=1.72; CI95%:1.15-2.60), poorly schooling mothers (PR=2.2; CI95%:0.96-5.02), from public schools (PR=4.16; CI95%:0.98-17.59), smokers (PR=1.91; CI95%:1.15-3.17). Conclusion: Demographic, socioeconomic and behavioural conditions were strongly associated with tooth loss. These associations were more evident when extractions for orthodontic reasons were not included in the analytical models.

HUBUNGAN ANTARA KEHILANGAN GIGI DAN KESEHATAN GIGI DENGAN KUALITAS HIDUP LANSIA DI PUSKESMAS LUBUK BUAYA KECAMATAN KOTO TANGAH

Tooth loss is a problem of dental and oral health that is often found in every individual. The prevalence of tooth loss increases with increasing age in a person, especially in the elderly. Tooth loss causes a decrease in oral function, especially in the function of mastication and physical function in the elderly, which then affects the quality of life. To determine the relationship of tooth loss with quality of life related to oral health in the elderly at Puskesmas Lubuk Buaya Kecamatan Koto Tangah.. The research uses observational analytic with a cross sectional study approach to 105 elderly people (≥ 60 years). Data collection was carried out by means of general interviews with respondents followed by oral examinations and lastly an interview was conducted using the Oral Health Impact Profile-14 questionnaire (OHIP-14). Data analysis used in this study is Chi-square statistical test. The elderly population in Kecamatan Koto Tangah had an average of 5-10 tooth loss with the most distribution were posterior tooth loss. As many as 50.5% of elderly people in Kecamatan Koto Tangah had a good quality of life. The majority of respondents with anterior-posterior tooth loss showed poor quality of life. Chi-square test showed that there was a significant relationship between the number of tooth loss and quality of life related to oral health (p &lt;0.001; OR=16.127) and there was a significant relationship between the location of tooth loss and quality of life related to oral health (p &lt;0.001 ; OR=9,274).
