Assaf M, Abu Libdeh K. Patterns of Tooth Extraction at a Student Dental Clinic in Palestine. Cureus 2023; 15:e46614. [PMID: 37841978 PMCID: PMC10569797 DOI: 10.7759/cureus.46614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 10/05/2023] [Indexed: 10/17/2023] Open
Abstract
INTRODUCTION While the ideal approach in dentistry is to preserve teeth and restore their functionality within the oral cavity, there are circumstances where tooth extraction becomes a necessary and routine dental procedure. In cases where preserving the tooth is not feasible due to unavoidable reasons, extraction may be the preferred choice to ensure the attainment of stable oral health. So, the present study aims to elaborate on the trends in extraction in student dental clinics in Palestine. MATERIALS AND METHODS The present study is a cross-sectional study. Informed consent was obtained from the participants before enrolling in the study. Patients from all the departments undergoing extraction procedures were included in the present study. Patient information such as age, sex, and main reason for tooth extraction was collected. A dental record was noted for the number of teeth extracted, the type of the teeth, and the condition of the teeth extracted. All the data collected was entered in the spreadsheet, and frequency was calculated for each variable. RESULTS The present study showed that third molars were the most extracted teeth, and dental caries was the primary cause of extraction. In the "clearance cases," lower canines were the most commonly extracted teeth. In the "non-clearance cases," lower incisors and lower first molars were the most commonly extracted teeth. Conclusion: The present study gives an overview of tooth extraction patterns in student dental clinics in Palestine. Further studies are required to evaluate and compare the prevalence and causes of tooth loss in different settings.

The Link between Stroke Risk and Orodental Status-A Comprehensive Review. J Clin Med 2022; 11:jcm11195854. [PMID: 36233721 PMCID: PMC9572898 DOI: 10.3390/jcm11195854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 09/21/2022] [Accepted: 09/29/2022] [Indexed: 11/17/2022] Open
Abstract
One of the primary causes of disability and mortality in the adult population worldwide is stroke. A person's general health is significantly impacted by their oral and dental health. People who have poor oral health are more susceptible to conditions such as stroke. Stroke risk has long been linked to oral and dental conditions. The risk of stroke and its cost impact on the healthcare systems appear to be significantly reduced as a result of the decline in the incidence and prevalence of oral and dental illnesses. Hypothetically, better management of oral hygiene and dental health lead to reduced stroke risk. To the authors' best knowledge, for the first time, the potential link between dental health and stroke were cross-examined. The most typical stroke symptoms, oral and dental illnesses linked to stroke, and the role of oral healthcare professionals in stroke prevention are revealed. The potential mediating processes and subsequent long-term cognitive and functional neurological outcomes are based on the available literature. It must be noted that periodontal diseases and tooth loss are two common oral health measures. Lack of knowledge on the effects of poor oral health on systemic health together with limited access to primary medical or dental care are considered to be partially responsible for the elevated risk of stroke. Concrete evidence confirming the associations between oral inflammatory conditions and stroke in large cohort prospective studies, stratifying association between oral disease severity and stroke risk and disease effects on stroke survival will be desirable. In terms of clinical pathology, a predictive model of stroke as a function of oral health status, and biomarkers of systemic inflammation could be useful for both cardiologists and dentists.

Tan LF, Chan YH, Merchant RA. Association between dentition and frailty and cognitive function in community-dwelling older adults. BMC Geriatr 2022; 22:614. [PMID: 35879659 PMCID: PMC9310464 DOI: 10.1186/s12877-022-03305-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 07/11/2022] [Indexed: 11/10/2022] Open
Abstract
Objectives To evaluate dentition status amongst community-dwelling older adults and its association with frailty and cognitive impairment. Methodology One thousand forty-seven community-dwelling older adults aged ≥65 years were surveyed in an epidemiologic population-based cohort study in Singapore between April 2015 and August 2016. Data on demographics, dentition status, chronic diseases, activities and instrumental activities on daily-living, cognition (age- and education-specific MMSE cut-offs), frailty (FRAIL scale), perceived health and functional status were collected. Multiple logistic regression was performed to examine the association between dentition, frailty and cognition. Results Mean age of participants was 71.2 ± 5.5 years. The prevalence of denture use was 70.7% and edentulism 7.9%. Compared to edentulousness, having teeth was associated with lower odds of cognitive impairment and higher odds of being robust or pre-frail. Denture-wearers compared with edentulous persons were less likely to be male, had higher education level and more likely be robust or pre-frail. Conclusion and implications There were significant associations between dentition status, frailty and cognition in our study where those with remining teeth and / or dentures had better overall outcomes. As oral health, frailty and cognitive impairments are all modifiable risk factors for healthy ageing, countries should consider population level screening for oral health, frailty and cognitive impairment.

Improvements in Dental Health and Dentists' Workload in Norway, 1992 to 2015. Int Dent J 2021; 72:399-406. [PMID: 34479721 PMCID: PMC9275092 DOI: 10.1016/j.identj.2021.07.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 07/20/2021] [Accepted: 07/23/2021] [Indexed: 01/03/2023] Open
Abstract
OBJECTIVES There has been a marked improvement in dental health in Norway during the last few decades. What effect has this had on provision of dental services, and how has private dental practitioners' assessment of their workload changed? METHODS The data were from 2 large surveys of private dental practitioners carried out in 1992 (n = 1056) and 2015 (n = 1237). An analysis of nonresponders showed that they were evenly distributed according to their age, gender, and the region in which their practice was located. Thus, the samples were representative of private dental practitioners. For 1 representative week in practice, the practitioners were asked to report the number of visits and the number of patients who received 1 or more of the following items of treatment: filling, crown, bridge, denture, root filling, extraction, and periodontal treatment. As a measure of patient supply, the responses from the following questions were used: "Based on an overall assessment of economy, workload, and other personal factors, is the number of regular patients adequate? If not, do you wish to have more patients or fewer patients?" RESULTS From 1992 to 2015, the annual number of visits per practitioner decreased by 23%. The number of patients per practitioner who received fillings, crowns, bridges, dentures, root fillings, or extractions decreased by 50% or more. The decrease was largest for practitioners younger than 35 years and for men. The proportion of practitioners who reported a deficit of patients increased from 20% to 37%. CONCLUSIONS Many dentists will have too few patients and a fall in income in the years to come is expected.

Abstract
Given the association between periodontal disease (PdD) and Alzheimer’s disease (AD), we examined correlations between states’ age-adjusted AD mortality rates, AD prevalence, subjective cognitive decline (SCD) prevalence, and oral health data. Data sources include the Centers for Disease Control and Prevention, scientific literature, and oral health rankings formulated by WalletHub.com and Toothbrush.org. Pearson (r) or Spearman (rs) correlation coefficients were generated and evaluated. AD mortality rates correlate with dental visits (r = − 0.50, p = 0.0003), partial (r = 0.39, p = 0.005) or total (r = 0.44, p = 0.001) edentulism, WalletHub.com (rs = 0.30, p = 0.03) and Toothbrush.org (rs = 0.35, p = 0.01) rankings. AD prevalence correlates with dental visits (r = − 0.30, p = 0.03), partial (r = 0.55, p = 0.00003) or total (r = 0.46, p = 0.0009) edentulism, prevalence of any (r = 0.38, p = 0.006) or severe-stage (r = 0.46, p = 0.0009) PdD, and WalletHub.com (rs = 0.38, p = 0.006) rankings. SCD prevalence in adults aged ≥ 45 years correlates with dental visits (r = − 0.69, p < 0.00001), partial (r = 0.33, p = 0.02) or total (r = 0.37, p = 0.008) edentulism, prevalence of any (r = 0.53, p = 0.0001) or severe-stage (r = 0.57, p = 0.00002) PdD, WalletHub.com (rs = 0.53, p = 0.00008) and Toothbrush.org (rs = 0.60, p < 0.00001) rankings. State metrics indicative of compromised oral health correlate with AD mortality rates, AD prevalence and SCD prevalence.

Association of Tooth Loss with New-Onset Parkinson's Disease: A Nationwide Population-Based Cohort Study. PARKINSONS DISEASE 2020; 2020:4760512. [PMID: 32765825 PMCID: PMC7374233 DOI: 10.1155/2020/4760512] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 06/10/2020] [Accepted: 06/19/2020] [Indexed: 01/10/2023]
Abstract
Introduction Tooth loss is associated with poor oral hygiene. During insufficient oral sanitation, focal infection and inflammation can occur and these reactions may induce systemic inflammation. Systemic inflammatory reaction may be related to the degeneration of dopamine neurons in the substantia nigra. We hypothesized that tooth loss is related to increased risk of new-onset Parkinson's disease. Methods Between 2003 and 2006, we included 153,165 participants from the national health insurance system-health screening cohort in Korea. The incidence of new-onset Parkinson's disease was defined as International Classification of Diseases-10 code “G20,” accompanying the prescription records for any anti-Parkinson's disease medication. Results Approximately 19.9% of the included participants had periodontal disease. After a median duration of 10.4 years, 1,227 (0.8%) cases of new-onset Parkinson's disease were noted. The number of tooth loss was positively related to an increased risk of new-onset Parkinson's disease. Contrastingly, the frequency of tooth brushings and dental clinic visits for any causes as well as competent dental care were negatively related to the development of new-onset Parkinson's disease. In multivariable analysis, the number of tooth loss (≥15) was positively related to new-onset Parkinson's disease development (hazard ratio: 1.38, 95% confidence interval (1.03–1.85), p=0.029, p for trend = 0.043) after adjusting variables. Conclusion Our study demonstrated that the number of tooth loss was positively correlated with a higher risk of new-onset Parkinson's disease development in a longitudinal study setting. Increased number of tooth loss may be an important risk indicator of new-onset Parkinson's disease.

Reasons for Tooth Extractions and Related Risk Factors in Adult Patients: A Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17072575. [PMID: 32283707 PMCID: PMC7178127 DOI: 10.3390/ijerph17072575] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 04/02/2020] [Accepted: 04/07/2020] [Indexed: 11/21/2022]
Abstract
Background: The aim of this study was to evaluate oral status, the reasons for tooth extractions and related risk factors in adult patients attending a hospital dental practice. Methods: 120 consecutive patients ranging from 23 to 91 years in age (mean age of 63.3 ± 15.8) having a total of 554 teeth extracted were included. Surveys about general health status were conducted and potential risk factors such as smoking, diabetes and age were investigated. Results: a total of 1795 teeth were missing after extraction procedures and the mean number of remaining teeth after the extraction process was 16.8 ± 9.1 per patient. Caries (52.2%) was the most common reason for extraction along with periodontal disease (35.7%). Males were more prone to extractions, with 394 of the teeth extracted out of the total of 554 (71.1%). Male sex (β = 2.89; 95% CI 1.26, 4.53; p = 0.001) and smoking habit (β = 2.95; 95% CI 1.12, 4.79; p = 0.002) were related to a higher number of teeth extracted. Age (β = −0.24; 95% CI −0.31, −0.16; p < 0.001) and diabetes (β = −4.47; 95% CI −7.61, −1.33; p = 0.006) were related to a higher number of missing teeth at evaluation time. Moreover, periodontal disease was more common as a reason of extraction among diabetic patients than among non-diabetic ones (p = 0.04). Conclusions: caries and periodontal disease were the most common causes of extraction in a relatively old study population: further screening strategies might be required for the early interception of caries and periodontal disease.

Abstract
OBJECTIVES The delivery of oral health services, diagnostics and treatment underwent significant changes in the 20th century thanks to achievements by pioneers in dentistry. The Golden Age of Dentistry in Vienna, Austria, was marked by renowned dentists like Bernhard Gottlieb in the 1930s. Data records from the outpatient department of this period have been found and served as a source from which to draw comparisons between those days and the present. To date, data supporting an overall perception of advances in dentistry during the last century in tooth preservation and patients' demands have been lacking. The aim of this study was to evaluate changes in treatments and patient characteristics between the interwar period and the present and to assess how treatments for dental emergencies developed. METHODS Patients' records were extracted from books handwritten from January to May 1933 and compared with electronically generated data from the same period in 2013. In total, patient data from 10 111 individuals (3878 in 1933 and 6233 in 2013) were analysed. Comparisons were undertaken for gender, age, place of residence, diagnosis and therapy. RESULTS Various statistically significant demographic and treatment differences were found between 1933 and 2013. Patients' mean ages in 2013 and 1933 were 42 and 31 years, respectively. In 2013, there were significantly more women than in 1933 (3378 vs 1936), with 54% women in 2013 and 50% women in 1933. In 2013, there were significantly fewer tooth extractions as dental emergency treatment than in 1933 (2% vs 34%). CONCLUSIONS Treatment in the outpatient department is much more conservative in the 21st century. The characteristics of patients visiting the outpatient department have changed over the generations, and treatment needs should be evaluated accordingly.

Abstract
We evaluated the association between oral health and mortality. The study population comprised 76,188 subjects aged 16–89 years at recruitment. The mean follow-up time was 3.4 ± 2.4 years. Subjects with a personal medical history of cancer or cardiovascular disease and death by casualty were excluded from the analysis. A full-mouth clinical examination was performed in order to assess dental plaque, dental calculus and gingival inflammation. The number of teeth and functional masticatory units <5 were recorded. Causes of death were ascertained from death certificates. Mortality risk was evaluated using Cox regression model with propensity score calibrated for each oral exposure. All-cause mortality risk were raised with dental plaque, gingival inflammation, >10 missing teeth and functional masticatory units <5. All-cancer mortality was positively associated with dental plaque and gingival inflammation. Non-cardiovascular and non-cancer mortality were also positively associated with high dental plaque (HR = 3.30, [95% CI: 1.76–6.17]), high gingival inflammation (HR = 2.86, [95% CI: 1.71–4.79]), >10 missing teeth (HR = 2.31, [95% CI: 1.40–3.82]) and functional masticatory units <5 (HR = 2.40 [95% CI 1.55–3.73]). Moreover, when ≥3 oral diseases were cumulated in the model, the risk increased for all-cause mortality (HR = 3.39, [95% CI: 2.51–5.42]), all-cancer mortality (HR = 3.59, [95% CI: 1.23–10.05]) and non-cardiovascular and non-cancer mortality (HR = 4.71, [95% CI: 1.74–12.7]). The present study indicates a postive linear association between oral health and mortality.

Abstract
OBJECTIVES To date there is little evidence of minimum intervention in relation to treatment patterns, particularly for initial carious lesions. The objective of this study was to investigate treatment provided to patients with a main diagnosis of coronal caries in relation to the severity of the caries lesion. METHODS A random sample of Australian dentists was surveyed by mailed questionnaires in 2009-2010 (response rate 67%). Data on services, patient characteristics and main diagnosis were collected from a service log. RESULTS Models of service rates adjusted for age, sex, insurance status and reason for visit showed that compared to the reference category of gross caries lesions, there were higher rates [rate ratio, 95% CI] of restorative services for initial [1.63, 1.31-2.03] and cavitated [1.69, 1.39-2.05] lesions, higher rates of prophylaxis for initial [3.77, 2.09-6.79] and cavitated [3.88, 2.29-6.58] lesions, lower rates of endodontic services for initial [0.07, 0.02-0.30] and cavitated [0.11, 0.04-0.30] lesions, and lower rates of extraction for initial [0.15, 0.06-0.34] and cavitated [0.15, 0.07-0.31] lesions. CONCLUSIONS Treatment of coronal caries was characterized by high rates of restorative services, but gross lesions had lower restorative rates and higher rates of endodontic and extraction services. There was little differentiation in treatment of coronal caries between initial and cavitated lesions, suggesting scope for increased management of initial carious lesions by the adoption of more minimum intervention approaches.

Abstract
BACKGROUND Tooth loss is associated with increased cardiovascular disease (CVD) mortality risk. This association may however be due to residual confounding. We aimed to assess whether tooth loss is associated with specific CVD mortality endpoints in a national population sample adjusting for potential confounders. METHODS AND RESULTS We used a prospective cohort design and data from the Scottish Health Survey. We combined data from surveys in 1995, 1998, 2003 and linked this to mortality records. Dental status was classified through self-reports as natural teeth only, natural teeth and dentures, and no natural teeth (edentate). Cox proportional hazards models were used to estimate risk of CVD mortality by dental status adjusting for potential confounders. The sample consisted of 12871 participants. They were followed for 8.0 (SD: 3.3) years. During 103173 person-years, there were 1480 cases of all-cause mortality, 498 of CVD, and 515 of cancer. After adjusting for demographic, socio-economic, behavioural and health status, edentate subjects had significantly higher risk of all-cause (HR, 1.30; 95% CI, 1.12,1.50) and CVD mortality (HR, 1.49; 95% CI, 1.16,1.92) compared to subjects with natural teeth only. Dental status was not significantly associated with cancer mortality in fully adjusted analysis. Further analysis for CVD mortality showed that in the fully adjusted model, edentate subjects had 2.97 (95% CI, 1.46, 6.05) times higher risk for stroke-related mortality. CONCLUSIONS In a national population sample of Scottish adults, being edentate was an independent predictor of total CVD mortality, although this was mainly driven by fatal stroke events.

Abstract
OBJECTIVE To examine if number of remaining teeth was associated with development of cardiovascular morbidity and mortality over 5-12 years. METHODS Prospective observational study among 1474 men and 1458 women born 1922, 1932, 1942 or 1952 from The Danish MONICA follow up study (MONItoring trends in and determinants of CArdiovascular disease) in 1987-88 and 1993-94. Subjects were followed in Danish registers for fatal and non-fatal cardiovascular disease, coronary heart disease or stroke. RESULTS Tooth loss was strongly associated with incidence of stroke, and to a lesser extent, incidence of cardiovascular disease and coronary heart disease, during averagely 7.5 years of follow-up. Compared to those with most teeth remaining, the edentulous suffered >3-fold increased Hazard (HR) of developing stroke (HR=3.25; 95% CI: 1.48-7.14), whereas the risk of developing any cardiovascular disease was increased by 50% (HR=1.50; 95% CI: 1.02-2.19). Risk for coronary heart disease was increased by 31%, but was not significant, after the adjustment for education, age, smoking, diabetes, alcohol intake, systolic blood pressure and body mass index (HR= 1.31; 95% CI: 0.74-2.31). Associations were similar for men and women. CONCLUSION These findings may have implications for future prevention of cardiovascular disease in general, and of stroke in particular, because tooth loss may serve as a simple, and early means to identify high-risk individuals.

Abstract
BACKGROUND Indigenous Australians have been reported in a range of studies to have worse health than non-Indigenous Australians. Among health care card holders, a financially disadvantaged group eligible for public-funded dental care, oral health may also be worse among Indigenous persons. The aims of this study were to examine the oral health of Indigenous compared to non-Indigenous adult public dental patients in terms of caries experience and periodontal status, controlling for age and gender of patient, type of care and geographic location. METHODS Patients were sampled randomly by state/territory dental services in 2001-2002. Dentists recorded oral health status at the initial visit of a course of care using written instructions. The samples were weighted in proportion to the numbers of public-funded dental patients for each state/territory. RESULTS Multivariate logistic regression showed that the presence of periodontal pockets of 6+ mm was higher (P < 0.05) among Indigenous compared to non-Indigenous patients (OR = 2.24, 1.34-3.76), after controlling for age and gender of patients, type of care and geographic location. Multivariate negative binomial regression analysis (RR: rate ratio) controlling for age and gender of patients, type of care and geographic location indicated that Indigenous patients had higher numbers of decayed teeth (RR = 1.42) and missing teeth (RR = 1.44) but lower numbers of filled teeth (RR = 0.51) compared to non-Indigenous patients (P < 0.05). There was no significant difference in the DMFT index, indicating similar cumulative past and present experience of dental caries for Indigenous and non-Indigenous patients. CONCLUSIONS Indigenous adult public dental patients had worse oral health status than non-Indigenous patients, with a higher percentage of Indigenous patients having periodontal pockets 6+ mm, and Indigenous patients having more decayed and missing teeth. Indigenous patients lack both timely and appropriate preventive and treatment services.

Abstract
BACKGROUND There has been no nationwide study in Japan on reasons for extraction of permanent teeth. This survey was aimed to determine the reasons for extraction of permanent teeth in Japan. METHODS Five thousand, one hudred and thirty-one dentists were selected by systematic selection from the 2004 membership directory of the Japan Dental Association. The dentists selected were asked to record the reason for each extraction of permanent teeth during a period of one week from February 1 through 7, 2005. Reasons for tooth extraction were assigned to five groups: caries, fracture of teeth weakened by caries or endodontics, periodontal diseases, orthodontics, and other reasons. RESULTS A total of 2,001 dentists (response rate of 39.1%) returned the questionnaires, and information on 9,115 extracted teeth from 7,499 patients was obtained. The results showed that caries and its sequela (totally 43.3%, 32.7% and 10.6%, respectively) and periodontal disease (41.8%) were the main reasons for teeth extraction. Extraction due to caries or fracture was commonly observed in all age groups over 15 years of age, whereas periodontal disease was predominant in the groups over 45 years of age. CONCLUSIONS Most of the permanent teeth were extracted due to caries and its sequela and periodontal disease. Prevention and care for dental caries for all age groups and periodontal disease for over middle age groups are required.

Abstract
OBJECTIVE To investigate gender differences in tooth loss among Chilean adolescents and its association with selected socio-economic indicators and oral-health-related behaviors. MATERIAL AND METHODS Data on 9,163 Chilean adolescents obtained using multistage random cluster procedures. Clinical recordings included information on missing teeth and the participants provided information on socio-demographic factors and oral-related behaviors. Two eruption-time-adjusted logistic regression analyses were used to investigate the associations between gender, tooth loss and socio-economic position/oral-health-related behaviors. RESULTS The association between gender and tooth loss remained after adjusting for age, eruption times in both the socio-economic position regression model and the oral-health-related behaviors model. Tooth loss followed social gradients for the variables paternal income and achieved parental education, with students reporting a paternal income < 100,000 US dollars (OR = 2.0), and having a father (OR = 1.8) and a mother (OR = 2.0) who achieved only primary school education being more likely to experience tooth loss. The adjusted regression model for behavioral indicators revealed that students who reported brushing their teeth once a day (OR = 1.6) were more likely to have experienced tooth loss than those who reported more frequent toothbrushing. Students who visited a dentist rarely (OR = 0.8) or never (OR = 0.5) were less likely to have lost first molars and/or incisors. CONCLUSIONS The results demonstrate that gender differences in tooth loss among young Chileans are related to socio-economic position; and selected oral-health-related behaviors after adjusting for eruption time variation.

Abstract
OBJECTIVES To investigate reasons for tooth extraction and its association with age and gender in Kuwait. SUBJECTS AND METHODS A record of all tooth extractions performed in 21 general dental practice centers during a 1-month period was logged on specially designed study forms. The patient's age and gender, number of teeth extracted, and the reason(s) for the extraction were recorded. RESULTS A total of 2,783 teeth were extracted in 1,604 patients (1.73 +/- 0.07 teeth per patient). Caries and periodontal disease were responsible for 43.7 and 37.4% of extractions, respectively. Caries was the principal cause for extraction in patients < or =40 years old (60.7%), while periodontal disease was the main cause of extractions in patients > or =40 years of age (63.0%). Extractions for caries and orthodontic reasons were more common in females, while extractions for periodontal disease were more prevalent in males. Molars and maxillary premolars were more commonly extracted due to caries, while mandibular premolars, and maxillary and mandibular anterior teeth (canines and incisors) were more commonly extracted due to periodontal disease. CONCLUSIONS The data show that caries is the principal cause for extractions in younger patients, while periodontal disease accounts for the majority of tooth extractions in patients older than 40 years. Furthermore, this study indicates that more teeth per patient are lost to periodontal disease than for any other reason.

Abstract
AIM To determine the current causes and pattern of tooth loss in Ile-Ife Nigeria. DESIGN A retrospective review of records of dental extraction patients. SETTING The dental hospitals of the Obafemi Awolowo University Teaching Hospital situated in South Western Nigeria. PARTICIPANTS All patients that had dental extractions between January 1996 and December 2002. METHOD Patients' case records were analysed for demographics, reason(s) for dental extraction, tooth/teeth extracted, method of extraction and complication(s). MAIN OUTCOME MEASURE Reasons for tooth extraction and the pattern of tooth loss. RESULTS 6348 (12.3%) of hospital attendees aged 4-102 years (mean 35 +/- 16.8 years) had extraction of 8338 teeth. A statistically significant female preponderance was observed. Dental caries was the leading cause of tooth loss (56.4%) followed by periodontal disease (24.6%). This shows a reversal of a trend reported in a previous study in the same location. Over half (69.2%) of the extracted teeth were molars (mostly mandibular). Only 4.1% extractions were trans alveolar. 3.9% were complicated by dry socket. CONCLUSION 12.3% of the hospital attendees had undergone dental extraction. Despite previous warnings of a steady rise in dental caries, it has become the leading cause of tooth loss in our hospital. The urgent need to institute standardised preventive measures was highlighted.

Abstract
OBJECTIVE To develop and test a scale for measuring expectancy of retaining teeth for life and to compare the estimates when using a global item with those obtained with a multi-item scale of measurement. MATERIAL AND METHODS The design of the study was cross-sectional selected and random sample surveys using a self-administered questionnaire or interview. There were two groups of patients and a national sample aged 16-79 years (n=1274); response rate 64%. The main results pertain to dentate subjects in a global group (n=615) and in a scale group (n=609). The outcome measure was expectancy of retaining natural teeth for life. Results. When using the global item, 92% (95% CL 89.8, 94.1) of the respondents believed they would definitely or possibly retain their natural teeth for life, significantly higher than the 81% (95% CL 77.6, 84.0) obtained with the 4-item conditional scale. Cronbach's alpha was 0.89 for the 4-item scale and the test-retest reliability moderate (kappa = 0.51; 0.77 for +/-1). The adults' belief in retaining teeth for life was significantly associated with having a live-in partner (p = 0.009) when the global question was the dependent variable; and sex (p = 0.000) and education (p = 0.004) when the 4-item scale was the dependent variable. Explained variance was 3.8% and 4.5%, respectively. Conclusions. The internal reliability of the 4-item scale was high. A significantly lower proportion of people reported belief in retaining natural teeth for life when employing the 4-item conditional scale than when the unconditional global question was used.

Abstract
AIM The purpose of this study was to assess the long-term influence of gingival inflammation on tooth loss. MATERIAL AND METHODS The data originated from a 26-year longitudinal study of Norwegian males, who practiced adequate daily oral home care and received "state-of-the-art" dental care. The initial examination in 1969 included 565 individuals aged between 16 and 34 years. Subsequent examinations took place in 1971, 1973, 1975, 1981, 1988 and 1995. Thus, the study covers the age range of 16-59 years. The teeth were divided into three tooth groups (I-III) reflecting the history of inflammation of the surrounding gingiva (gingival index (GI) scores) over 26 years: (I) teeth with surrounding gingival units scoring a minimum of one site with GI=0 and a maximum of three sites with GI=1, (II) teeth with surrounding gingival units scoring a minimum of one site with GI=1 and a maximum of three sites with GI=2 over the observation periods and (III) teeth with surrounding gingival units always scoring a minimum of GI=2 (bleeding on probing) at all sites over the observation period. RESULTS At baseline (1969), out of possible 15,820 teeth (565 x 28), 15,383 teeth were present. Four hundred and thirty-seven teeth had already been missing for unknown reasons. By 1995, 13,159 teeth were reexamined, i.e. over the 26-year observation period only 126 (0.95%) teeth were lost. Only 16 (0.28%) of 5793 teeth belonging to GI-Severity Group I were lost. In the GI-Severity Group II, however, 78 (2.28%) out of 3348 teeth were lost, and 13 (11.21%) of 103 teeth with GI-Severity Group III were lost. Teeth with GI-Severity Group III yielded an odds ratio for tooth loss that was 46 times higher than that of teeth with GI-Severity Group I, and five times higher than that of teeth with GI-Severity Group II over 26 years. Furthermore, teeth with the GI-Severity Group II had a nine times higher risk for tooth loss than teeth with the GI-Severity Group I. The GI-Severity Group I retained 99.5% of the teeth after a tooth age of 51 years. The GI-Severity Group II retained 93.8% of the teeth after a tooth age of 50 years. However, in the GI-Severity Group III, 63.4% of the teeth were retained for a tooth age of 47 years. CONCLUSIONS Teeth surrounded with inflammation-free gingival tissues were maintained for a tooth age of 51 years, while teeth consistently surrounded with inflamed gingivae yielded a 46-times higher risk to be lost. Only two-thirds of such teeth were maintained throughout the 26-year observation period. This documents the role of gingival inflammation as a risk factor for future tooth loss.

Abstract
OBJECTIVE To describe oral health in the Anangu Pitjantjatjaraku lands in South Australia and to compare with earlier surveys and national data. DESIGN Descriptive. SETTING Data were collected at the time of dental care service provision, according to World Health Organization protocols, at the request of the Nganampa Health Council on optical mark reader forms. PARTICIPANTS There were 356 Anangu adults and 317 children surveyed. RESULTS The mean number of teeth affected by dental caries in the deciduous dentition in young children, aged 5-6 years, was double (mean 3.20) that of the overall Australian child population aged 5-6 years (mean 1.44). In contrast to the decline in deciduous caries in Australian children generally, Anangu children aged 5-9 years had a 42% increase in the mean number of teeth affected since 1987. Adults experienced low levels of dental caries, but severe periodontal disease was more prevalent among diabetics (79%) compared with-non-diabetics (13.8%). Tooth loss was found more frequently among adults with diabetes (mean 5.51) than non-diabetics (mean 1.53). CONCLUSIONS Oral health promotion strategies, in association with general health strategies, need to be developed to improve oral health in this remote Aboriginal population.

Abstract
The aim of this study is to document reasons for tooth loss in disadvantaged Jordanians who seek free dental care at the University Hospital/Dental Clinics. A 4-year (1998-2001) prospective study was undertaken involving 2200 randomly selected patients from this subpopulation. Of their 3069 lost teeth, 46.9% were lost due to caries and its sequel; 18% were lost because of periodontal disease; 8% were lost for a combination of caries and periodontal disease; 19.4% for pre-prosthetic reasons; 4% for orthodontic reasons; 2.8% for eruption problems and 0.7% due to trauma. Logistic regression analysis for reasons of tooth loss in this sector revealed that caries and its sequel was the predominant cause of tooth loss in patients <or=40 years of age whereas periodontal extractions were predominant for the above 40-year-old group. In addition, the most frequently extracted teeth, due to caries, were lower first and second molars while lower incisors were most commonly extracted for periodontal disease. Premolars were extracted for orthodontic reasons, upper incisors for trauma, third molars for eruption problems and canines for pre-prosthetic reasons. In conclusion, dental caries was the main reason for removal of teeth in adults attending the University of Jordan free dental casualty clinic. Therefore, in order to reduce the rate of dental extractions in this sector of the Jordanian population, efforts should focus on prevention and treatment of caries. Efforts should also be made to change the values and beliefs of this sector towards the importance of natural dentition.

Abstract
The aim of the study was to examine the oral health and treatment needs of chronically hospitalized psychiatric patients in Israel. Ten percent of the patients hospitalized for more than 2 years in the 18 psychiatric institutions in Israel were selected at random. The dental status (DMF-T index) was calculated, demographic and medical data were retrieved from the files. Of the 431 patients examined (250 men, 181 women, average age 54 years) 312 patients had only partial natural dentition. The average DMF-T score was 26.74 (out of 32), one of the highest in the literature. The caries component accounted for 2.3% of the DMF-T, the missing teeth component 72% and the restored teeth component 5%. There was an adverse correlation between age and caries and between duration of hospitalization and number of teeth. The average number of carious and missing teeth was higher than in the healthy population. No all-edentulous patients had dentures. These findings confirm the urgent need for an intervention program to improve dental health care in high-risk, difficult-to-treat, psychiatric chronic inpatients.

Abstract
BACKGROUND, AIMS Over the past 10 years several studies have been published pointing towards a relationship between periodontal disease and various systemic disorders or diseases. The purpose of this retrospective study was to investigate the occurrence of self-reported systemic disorders in patients referred to a specialist clinic for periodontal treatment and to explore possible relationships between general health and periodontal disease severity in this population. MATERIAL AND METHODS Data were collected from the dental records and the health questionnaires of 1006 subjects. Stepwise multiple linear regression analyses were adopted to calculate correlations between systemic disorders as independent variables and number of remaining teeth and the relative frequency of periodontal pockets of 5 mm or more, respectively, as the dependent variable. RESULTS The number of remaining teeth was significantly and positively correlated to the presence of cardiovascular disease, diabetes and rheumatoid disease after adjustment for age, sex and smoking. The relative frequency of diseased sites, however, was not significantly correlated to any one of the investigated systemic health disorders. CONCLUSION No significant associations between investigated systemic disorders and periodontal disease severity were found if the relative frequency of deep periodontal pockets was used as the clinical parameter for periodontal disease severity. However, cardiovascular disease, diabetes and rheumatoid disease were found to be significantly correlated to number of lost teeth, which may represent one aspect of periodontal health. This result held true in nonsmokers only.

Abstract
BACKGROUND Many studies have reported the association between poor oral health and coronary heart disease or stroke, but few of them evaluated peripheral arterial disease (PAD). Hence, in this study we examined the associations between oral health and PAD. METHODS AND RESULTS In the prospective study of 45,136 eligible male health professionals free of cardiovascular diseases at baseline, we identified 342 cases of PAD during a 12-year follow-up period. We evaluated the association between different measures of oral diseases and the occurrence of PAD. Baseline number of teeth was not related to the risk of PAD, but cumulative incident tooth loss was significantly associated with elevated risk of subsequent occurrence of PAD. The relative risk for history of periodontal disease was 1.41 (95% CI, 1.12 to 1.77) and for any tooth loss during the follow-up period was 1.39 (95% CI, 1.07 to 1.82), controlling for traditional risk factors of cardiovascular disease. Among men with a history of periodontal diseases, the relative risk of tooth loss increased to 1.88 (95% CI, 1.27 to 2.77), whereas no association was found between tooth loss and PAD among those without periodontal diseases (RR, 0.92; 95% CI, 0.61 to 1.38). We further explored the potential induction period of tooth loss and found that tooth loss in the previous 2 to 6 years was most strongly associated with PAD. CONCLUSIONS We found that incident tooth loss was significantly associated with PAD, especially among men with periodontal diseases. The results support a potential oral infection-inflammation pathway.

Abstract
OBJECTIVES Very few studies have reported tooth loss incidence over a period of 10 years or more, and fewer have reported tooth loss occurrence in subjects aged 80 and older, so that the long-term pattern of tooth loss in the very old is largely unknown. This study assessed 13-15-year tooth loss incidence among a cohort of Iowans, aged 65 and older at baseline. METHODS Oral examinations were conducted on 520 subjects beginning in 1983, and periodically until 1988, with another round of examinations conducted on surviving members of the initial cohort during 1996-98. RESULTS Of the 73 remaining subjects, 45 subjects lost a total of 153 teeth during the period (mean=2.1 teeth lost), with a maximum of 17 teeth lost. Molars were the most commonly lost teeth, while canines and maxillary incisors were the least commonly lost. Bivariate analyses found that tooth loss was associated with untreated decay at baseline and level of periodontal attachment loss at earlier examinations. Logistic regression identified only greater severity of attachment loss as a significant risk factor for tooth loss (Adjusted odds ratio=2.4, P=0.006). The impact of tooth loss on subjects' lives was assessed using OHIP and other questions. The occurrence of tooth loss over the study period had little impact, but the number of remaining teeth significantly impacted subjects' ability to eat or chew food, swallow, or their willingness to smile. CONCLUSIONS These results suggest that tooth loss continues in the very old, that periodontal attachment loss is associated with tooth loss in this age group, and that loss of teeth over one's lifetime does affect certain quality-of-life measures.

Abstract
A total of 85 Finnish alcohol-dependent subjects and 53 controls were studied with panoramic radiography. The aim was to study the possible associations between prolonged alcohol consumption and dental health. The mean number of teeth, caries lesions, endodontic treatments, periapical lesions, marginal bone loss, and periodontal infrabony pockets was studied. The subjects met the diagnostic criteria of alcohol dependence as set out in DSM-IV and ICD-10. The control group comprised social drinking volunteers with an AUDIT score < or =8. For the final results the subjects were divided into groups on the basis of sex and age. The social backgrounds of the subjects were similar, except for employment and smoking. The results show significantly fewer teeth and more caries in the alcoholic group. There was a tendency for the alcoholics <45 years of age to have more endodontically treated teeth than the controls, but no difference in the number of periapical lesions in endodontically treated teeth was found. Horizontal bone loss and the presence of calculus were more frequent in alcoholic men than in alcoholic women. Significantly more horizontal bone loss was observed in the group of alcoholic nonsmokers than in nonalcoholic nonsmokers. In the nonsmoking groups alcoholics had significantly more periodontal destruction than the nonsmoking controls. We conclude that radiological dental health among individuals dependent on alcohol is weakened by more caries, more horizontal bone loss, and more numerous vertical infrabony pockets than social drinkers.

Abstract
AIMS Although Scotland has the highest proportion of edentulous adults in the UK, the frequency of edentulousness has fallen by 21% during the last 20 years. This study, carried out in 1999, was designed to establish whether the reasons for tooth loss have also changed since 1984 when they were last determined. METHODS The Scottish Dental Practice Board provided the names of every fourth dentist on its list among which 425 general dental practitioners were identified. They were asked to record permanent tooth extractions for 1 week, specifying the age, sex and dental attendance of patients who underwent extractions and the reasons for these extractions. 352 dentists took part: a response rate of 82.8%. RESULTS The study confirmed that there has been a reduction in the number of extractions between 1984 and 1999: there were 25% fewer teeth extracted per patient and 30% fewer per dentist per week. From 0-20 years of age, orthodontics has replaced caries as the commonest reason for extraction and in all age groups over 20 years, caries has become the commonest reason in contrast to 1984 when periodontal disease was the principal reason in patients over 40 years old. CONCLUSIONS Caries and its sequelae remain the most important cause of tooth loss throughout adult life in Scotland and, therefore, caries prevention and maintenance of restorations are of great importance at all ages.

Abstract
OBJECTIVES To compare reasons for extraction in 1997 and 1986, and to consider regional variations for the 1997 data. METHODS Random samples of general dental practitioners (GDPs) completed questionnaires for all extractions for 4 weeks in 1986 and in 1997. Reasons for extraction by region were compared for the 1997 data. RESULTS 220 and 562 GDPs participated in 1986 and 1997, respectively, averaging 24 extractions in 1986 and 20 in 1997. 'Caries' remained the commonest reason for < or =50-year-olds (excluding 'ortho'), but peaked a decade later than in 1986. One-third of 'perio' extractions in both studies were for 51-60-year-olds, but in 1997 there were fewer such extractions for < or =40-year-olds and more for >70-year-olds than in 1986. In 1997 'caries' and 'perio' extractions remained equally common for patients >50 years, but there were far more extractions for both reasons for >80-year-olds. Patients < or =30 years in S. England and in the Midlands/E. Anglia had more 'ortho' than 'caries' extractions, whereas 'caries' predominated in N. England and in Wales. 'Caries' exceeded 'perio' for patients >40 years in Wales, whereas in the three English regions the two reasons were equally frequent. CONCLUSIONS Comparisons of results of two studies conducted a decade apart indicate that there have been some changes in reasons for extraction. Overall, mean number of extractions per dentist has declined, and it appears that the trend is for extractions due to the common dental diseases to be carried out later in life. The 1997 data also suggest that young patients in Wales and N. England are relatively disadvantaged, having more caries and less orthodontic treatment than those in other parts of England.

Abstract
AIMS/OBJECTIVES The aim of this study was to investigate the association of extractions by the diagnoses of caries, pulpal/periapical infection and periodontal disease, controlling for visit type, insurance and age. DESIGN Cross-sectional analysis of the 1993-94 wave of a longitudinal study. SETTING Private general dental practice. PARTICIPANTS A random sample of Australian registered dentists, (response rate = 74%). METHODS Practitioners completed service logs over one to two typical clinical days. MAIN OUTCOME MEASURE Percentage of patients receiving extractions. RESULTS Overall, 7.05% of patients received extractions, with the highest percentages occurring for persons with caries (7.90%), periodontal disease (17.45%) and pulpal/periapical infection (17.54%). Odds of extraction were higher at emergency visits for insured and uninsured patients compared to non-emergency visits by insured patients, while odds of extraction (Logistic regression: OR = Odds ratio; 95% CI) were higher for 18-44 year-olds with caries (OR = 1.44; 1.09-1.89), for 18-44 (OR = 1.84; 1.34-2.54) and 45+ year-olds (OR = 1.83; 1.27-2.63) with pulpal/periapical infection, and for 45+ year-olds (OR = 6.82; 4.68-9.95) with periodontal disease. CONCLUSIONS There were different age-specific causes of extraction, controlling for visit type and insurance. Effect sizes were highest for pulpal/periapical infection and periodontal disease, but caries remained a major cause of tooth loss due to the higher prevalence of this condition.

Abstract
AIM To identify the reasons for tooth extraction in Recife, Brazil and to test whether they differ by socio-economic groups and levels of caries experience. DESIGN Cross-sectional survey. SETTING Ten health centres of the public health system and ten health centres of insurance companies. PARTICIPANTS Patients attending health centres. METHODS Ten dentists from each selected centre and two patients from each selected dentist were randomly selected from; the list of all health centres in Recife, all dentists carrying out dental extractions at each selected centre and all patients who had an appointment with the selected dentists respectively. Participants were examined by both the researcher (AC) and dentists. OUTCOME MEASURE Reasons for tooth extraction. RESULTS Of the 404 teeth extracted, 70.3 per cent were because of caries and its sequelae; 15.1 per cent because of periodontal disease; 6.4 per cent for pre-prosthetic reasons; 3.7 per cent wisdom teeth, 2.5 per cent for orthodontic reasons and 1 per cent for trauma and patient's request. A trend was observed for patients with less than secondary school education and lower salaries to have more tooth extraction due to caries, but the differences were not of statistical significance.

Abstract
OBJECTIVES The objectives of this investigation were to study determinants of apical periodontitis among Lithuanians who were 35 to 44 years old and to study possible associations between apical periodontitis, relevant general diseases, and perceived general health. STUDY DESIGN Information was collected from a randomly selected sample, consisting of 147 individuals from Vilnius, Lithuania. Aspects of oral and general health, health-related habits and attitudes, and social parameters were used as independent variables, with various aspects of apical periodontitis as the dependent variable. Associations were tested by regression analysis. RESULTS Apical periodontitis was highly prevalent in this Lithuanian population. Oral health-related variables showed the strongest association with apical periodontitis. Decayed and filled teeth scores were found to be strongly associated with periapical disease, and sound teeth were strongly associated with periapical health. In addition, behavioral variables were found to be important disease determinants. CONCLUSIONS Apical periodontitis appeared to be an oral health problem closely related to dental caries. No association could be detected between general diseases and apical periodontitis, but an association between perceived general health and apical periodontitis was demonstrated.

Abstract
This investigation was carried out to determine the reasons for extraction of permanent teeth in Jordan. A random sample of 200 Jordanian Dentists (1:10) were asked to record reasons for the extraction of permanent teeth during a two week period. Of the 139 dentists responding, only 97 dentists extracted teeth during the study period. A total of 934 teeth were extracted from 582 patients, of these 33.4 per cent were extracted for periodontal disease, and 27.6 per cent because of caries and its sequelae. The study suggests caries and its consequences affected tooth loss throughout life while the rate of tooth loss due to periodontal disease increases with age.

Abstract
OBJECTIVE To determine the reasons for clinically defined need for tooth extractions were examined. DESIGN Descriptive survey; interview and clinical data. SETTING The City of North York, Canada. SUBJECTS 1,531 dentate adults aged 65 and over, 69% being nursing home residents. MEASUREMENTS Age, sex, type of residence and dental attendance pattern. OUTCOME MEASURE Normative need for tooth extraction. RESULTS One or more extractions were required by 38% of nursing home residents and 21% of independently-living subjects. The mean number of teeth indicated for extraction were 1.4 and 0.6, respectively. Among nursing home residents, caries was more often the reason for extraction for almost all tooth types, but for independently-living subjects periodontal reasons were more common. Overall, a significantly higher proportion of nursing home residents needed extractions due to both caries and periodontal reasons (25% and 16%) compared to subjects who lived independently (10% and 11%). For nursing home residents in all age groups, more subjects required caries-related extractions, but for independently-living subjects about equal proportions required extractions due to caries and periodontal diseases. Although the percentage of subjects requiring extraction due to caries varied significantly by age and residence type, the percentage needing extractions due to periodontal diseases showed slight variation and remained under 20%. CONCLUSION This study indicates that among high risk groups of older adults caries continues to be the major reason for tooth extraction. However, problems with sampling limit the external validity of these results.

Abstract
The occurrence of missing teeth is a vexing and growing problem in epidemiological studies of dental disease. The number of units of measurement (i.e., teeth/tooth sites) varies between persons and may affect summary statistics in descriptive studies as well as in analytical studies. The purpose of the present study was to develop a general model to adjust summary statistics for missing teeth. The proposed method was applied to alveolar bone loss in current smokers, former smokers, and non-smokers, from 45 to 64 years of age (n = 812). Alveolar bone loss was measured on bitewing radiographs. The adjustment method was based on the assumption that the probability of losing a tooth was an increasing function of alveolar bone loss. The main finding of the present study was that mean alveolar bone loss increased after adjustment for the number of missing teeth. This increase was larger for current smokers than for non-smokers, indicating that the effects of smoking were slightly underestimated when missing sites were ignored. Further research is required for the model to be applied to other data, estimating different types of dental disease with various degrees of disease prevalence and various numbers of missing teeth, and for validating the adjustment method by means of longitudinal data.

Abstract
The aim of this study was to compare changes in periodontal status in a Swedish population over a period of 20 years. Cross-sectional studies were carried out in Jönköping County in 1973, 1983, and 1993. Individuals were randomly selected from the following age groups: 20, 30, 40, 50, 60, and 70 years. A total of 600 individuals were examined in 1973, 597 in 1983, and 584 in 1993. The number of dentate individuals was 537 in 1973, 550 in 1983, and 552 in 1993. Based on clinical data and full mouth intra-oral radiographs, all individuals were classified into 5 groups according to the severity of the periodontal disease experience. Individuals were classified as having a healthy periodontium (group 1), gingivitis without signs of alveolar bone loss (group 2), moderate alveolar bone loss not exceeding 1/3 of the normal alveolar bone height (group 3), severe alveolar bone loss ranging between 1/3 and 2/3 of the normal alveolar bone height (group 4), or alveolar bone loss exceeding 2/3 of the normal bone height and angular bony defects and/or furcation defects (group 5). During these 20 years, the number of individuals in groups 1 and 2 increased from 49% in 1973 to 60% in 1993. In addition, there was a decrease in the number of individuals in group 3, the group with moderate periodontal bone loss. Groups 4 and 5 comprised 13% of the population and showed no change in general between 1983 and 1993. The individuals comprising these groups in 1993, however, had more teeth than those who comprised these groups in 1983; on the average, the individuals in disease group 4 had 4 more teeth and those in disease group 5, 2 more teeth per subject. In 1973, these 2 groups were considerably smaller, probably because of wider indications for tooth extractions and fewer possibilities for periodontal care which meant that many of these individuals had become edentulous and were not placed in a group. Individuals in groups 3, 4, and 5 were subdivided according to the number of surfaces (%) with gingivitis and periodontal pockets (> or =4 mm). In 1993, 20%, 42%. and 67% of the individuals in groups 3, 4, and 5 respectively were classified as diseased and in need of periodontal therapy with >20% bleeding sites and >10% sites with periodontal pockets > or =4 mm. In conclusion, an increase in the number of individuals with no marginal bone loss and a decrease in the number of individuals with moderate alveolar bone loss can be seen. The prevalence of individuals in the severe periodontal disease groups (4, 5) was unchanged during the last 10 years; however, the number of teeth per subject increased.

Abstract
Numerous epidemiological studies have shown that caries is the main reason for tooth loss. More recent epidemiological data seem to show an increasing trend of tooth loss due to periodontal reasons rather than caries. In considering the issue of periodontal disease and tooth loss the following observations were made. The presence of initial attachment loss, bone height and the habit of smoking significantly increase the risk of tooth mortality. There is a strong correlation between smoking, the severity of periodontal disease and tooth mortality. Cross-sectional population surveys of tooth loss reported lower anterior teeth to be the most frequently extracted due to periodontal reasons, followed by upper anteriors and upper second molars. However, in long term maintenance studies, molars were lost most frequently. Periodontal reasons for tooth loss were mainly mobility followed by furcation involvement. Periodontal surgery did not significantly enhance tooth retention in high risk groups. Ethnic differences observed were not significant and would need further investigations to address variables such as cultural differences, health habits, diet and socio-economic status. In conclusion, periodontal tooth mortality was found to be associated with the loss of periodontal attachment and risk groups with advanced periodontitis contributing to major tooth loss in a minority of the population.

Abstract
This study describes the incidence of tooth loss over a 10-year period in a population of rural Chinese, initially aged between 20 and 80 years. Among the 587 persons who participated in a baseline examination in 1984, 440 persons were available for a follow-up study in 1994. A total of 31 persons, mainly aged 50+ years at baseline, had become completely edentulous. Between 45% and 96% of the persons lost at least one tooth, and the average number of teeth lost ranged between 1.0 and 7.2. The distribution of the number of teeth lost was skew, indicating that a minor group of subjects had a substantially higher risk of tooth loss than the majority. Logistic regression analysis identified six significant predictors of tooth loss among those who remained dentate: age, a high number of teeth with dentinal caries lesions, a high number of teeth with caries lesions of any type, presence of teeth with attachment loss > or = 7 mm, presence of mobile teeth, and a low percentage of sites with subgingival calculus deposits. At the subject level, caries variables and periodontal disease variables seemed equally important predictors of the incidence of tooth loss over 10 years, but at the tooth level caries was a predominant cause of tooth loss in all age groups.

Abstract
OBJECTIVES To investigate the primary reasons for the extraction of permanent teeth in adults and to validate the dentists' reasons for extraction. METHODS Twenty-one dentists in the Greater Manchester area took part in the study. These dentists provided extracted teeth stored in 10% buffered formal saline together with details of the patient's age, sex, dental attendance pattern and the reason for extraction. In order to validate the reasons for extraction, teeth were examined for the presence or absence of coronal and root caries. A subgroup of 80 teeth, half of which were extracted primarily for caries and half for periodontal reasons were selected, stained and attachment loss measured at six sites per tooth to validate periodontal reasons for extraction. RESULTS Three hundred and eighty-nine teeth were collected of which 37% were extracted primarily due to caries and 29% due to periodontal disease. Caries was the main reason for extraction in patients under 50 years, whereas periodontal disease was the commonest reason in the over-50 age group. Irregular attenders had more extractions for caries than regular attenders but attendance pattern did not affect the proportion of teeth extracted for periodontal reasons. The mean greatest loss of attachment on teeth extracted for periodontal reasons was 12 mm compared with 6.5 mm for caries. CONCLUSION In this group of patients caries was the most common reason for extraction of teeth but periodontal disease became a more important reason for extraction after 50 years of age. The study validated the dentists' given reason for extraction.

Abstract
The retention of natural teeth among the elderly is increasing and, in recent studies, dental caries has been identified as the main reason for teeth being extracted. The 5-year incidence of tooth loss and dental caries and the most crucial dental factors for tooth extraction were studied in a random sample of 60-, 70- and 80-year-old inhabitants of Gothenburg. Of the 208 persons examined at baseline, 148 (71%) participated in the follow-up examination: 69, 51 and 28 respectively in the different age groups. In all, 110 teeth had been extracted during the period in 40% of the participants. Only 9 persons had lost three or more teeth. The mean numbers of remaining teeth were 22. 18 and 15 respectively in the 60-, 70- and 80-year age groups and the mean numbers of teeth lost during the 5-year period increased with age from 0.4 in the 60-year-olds to 0.8 and 1.4 in the 70- and 80-year-olds (P < 0.05). The major reason for tooth extraction was dental caries and it was found in 60% of all cases and at a higher rate of 77% in the oldest age group. Fifty-one per cent had developed new coronal carious lesions and 61% had new root carious lesions, while 27% had not developed caries during the period. The mean 5-year increment in decayed and filled coronal surfaces increased with age from 2.3 in the 60-year-olds to 3.7 and 5.3 in the 70- and 80-year-olds (N.S.I. The increment in decayed and filled root surfaces was higher in women than men, 3.4 compared with 1.8 (N.S.), which also increased with age from 1.4 in the 60-year-olds to 2.4 and 5.5 in the 70- and 80-year-olds (P < 0.0001). It was concluded from this study that few teeth had been lost during the 5-year period but that dental caries still appeared to be a serious problem among some very elderly people.

Abstract
In a study of tooth extractions in general dental practices in Ontario, Canada, 165 dental practitioners provided information on 6134 patients attending during a reference week. Of these, 11.6 per cent of patients had one or more permanent teeth extracted. Periodontal disease was given as the reason for 35.9 per cent of these extractions and caries for 28.9 per cent. Analysis by tooth type showed that third molars were the most common tooth type extracted. However, there were differences in the types of teeth extracted by age. Posterior teeth were most frequently lost by the younger age groups and anterior teeth by older subjects. There were also differences in the reasons for the loss of different tooth types. A comparison of these results with those of a similar study in Scotland suggests that age and tooth type does not account for the excess of extractions due to periodontal disease in this Canadian population. Differences in practice patterns and attitudes towards the retention of teeth may be contributing factors.

Abstract
1. The interpretation of epidemiological data of periodontal disease is difficult, due to inconsistencies in the methodology used. It is not possible, therefore, to accurately assess if the prevalence of the periodontal diseases shows a world-wide decline. As long as the disease is assessed through accumulated clinical attachment loss, retention of the natural dentition in older ages entails increased prevalence in these cohorts. Contemporary epidemiological studies should ideally employ full-mouth examination of the periodontal tissues. Partial recording estimates are generally biased, especially when the prevalence of the disease is low. 2. Early-onset periodontitis is infrequent in all populations. Adult periodontitis is rather prevalent; however, advanced disease affects limited subfractions of the population (probably less than 10 to 15%). Although prevalence figures vary with race and geographic region, in most cases, the progression pattern of the disease seems compatible with the retention of a functional dentition throughout life. 3. Of a plethora of behavioral and environmental risk markers identified by multi-variate analysis, smoking and presence of certain subgingival microorganisms have been proven to be true risk factors. The same holds true for diabetes mellitus, a systemic condition that confers a risk for periodontal disease which is independent of the effect of other significant factors. 4. In certain cases, periodontal infections appear to have a systemic impact on the host. Most recent data indicate that periodontal disease may confer risk for coronary heart disease and pre-term low birth weight.

Abstract
The purpose of the study is to collect information on the reasons given by dentists, randomly selected from the Italian Dental and Maxillo-Facial Association's, for extracting permanent teeth in Italy. From the 164 dentists responding, 1056 teeth in 839 patients were extracted during two weeks of working activity. More than two-thirds of the teeth were extracted for dental caries (34.4%) and periodontal disease (33.1%). The mean number of teeth extracted per patient showed a significant increasing trend with increasing age, being 1.09 in those from 16 to 39 yr, 1.25 in the 40-59-yr-old group, to 1.54 in those over 59 yr of age (F = 21.44; P < 0.0001). The third molar was the most frequently extracted tooth and 41.3% were removed due to impaction reasons, in particular from the mandible. The first and second molars and the premolars were extracted most often because of caries; more than half of the incisors and the canines were extracted for periodontal reasons; the majority of the teeth removed for prosthetic reasons, 57.1%, were incisors and canines, especially in the mandible; of the teeth extracted for orthodontic reasons, 47.4% were first and second premolars. The prevalence of subjects with at least one tooth extracted for dental caries and for orthodontic reasons were respectively significantly higher in the irregular than the regular attenders (chi-square = 46.55; P < 0.0001), and in the regular than the irregular dental attenders (chi-square = 63.12; P < 0.0001). Dental practitioners should promote targeted initiatives for prevention and treatment of diseases in order to reduce in particular the incidence of tooth extraction because of caries and periodontal disease.

Abstract
While substantial proportions of the population of Ontario, Canada continue to have teeth extracted, little is known about the reasons for this loss. In this survey of Ontario general dental practitioners, 128 dentists provided information on 6143 patients they saw during a reference week. Approximately one-in-seven of these patients had or were going to have one or more extractions as part of their current course of treatment. The mean number of extractions for patients having at least one tooth taken out was 2.3 (SD = 2.5). Emergency patients were more likely than regular patients to have at least one extraction but, on average, had fewer teeth taken out. Orthodontic considerations were the main reason for tooth loss in childhood, caries continued to be an important cause of tooth loss at all ages and periodontal disease accounted for more teeth lost after 40 years of age than caries. This study differs from almost all others in finding that, overall, more permanent teeth were extracted because of periodontal disease than because of caries. The former accounted for 35.9% of teeth lost and the latter for 28.9%. While this may be due to methodological differences between this and other studies, it is consistent with epidemiological data on periodontal disease in the Ontario population and data showing that Ontarians receive little in the way of periodontal care.
