Delayed oral health care due to cost among US adults with diabetes, 2018-2019.

BACKGROUND: Although untreated periodontitis increases the risk of developing diabetic complications, people with diabetes are less likely to use dental services. The authors estimated the prevalence of reporting delayed needed oral health care due to cost and associated risk indicators by diabetes status. METHODS: The authors analyzed data for 43,291 adults who participated in the 2018 and 2019 Medical Expenditure Panel Surveys. The authors used t tests to compare crude estimates of delayed oral health care by diabetes status. Adjusted estimates were obtained from logistic regression models that controlled for sociodemographic, medical and dental insurance, health status, and geographic variables. Multivariable logistic regression models were run separately for adults with and without diabetes to identify factors that were associated with delayed oral health care. RESULTS: After controlling for covariates, the difference in delayed oral health care prevalence between adults with diabetes (18%) and without diabetes (16%) remained significant. Lack of medical insurance and fair or poor self-rated health status were the highest predictors of delayed oral health care among those with diabetes. CONCLUSIONS: Despite guidelines, factors other than biology and perceived need may impede access to oral health care for people with diabetes. PRACTICAL IMPLICATIONS: For uninsured adults, policies should prioritize enhancing access to regular ambulatory care and promoting awareness about the importance of preventing and treating dental conditions. In addition, addressing the medical and psychosocial aspects of diabetes in affected patients could affect positively their overall sense of well-being and self-rated health status, potentially encouraging greater use of oral health care services.

Prevalence and mean number of teeth with amalgam and nonamalgam restorations, United States, 2015 through 2018.

BACKGROUND: Amalgam has been used for more than 150 years as a safe and reliable restorative material. The authors described the occurrence of amalgam and nonamalgam restorations in the United States in primary and permanent teeth across age groups and according to sociodemographic characteristics. METHODS: The authors used clinical examination data from the National Health and Nutrition Examination Survey 2015-2018 for participants 2 years and older (n = 17,040). The authors estimated the prevalence and mean number of amalgam and nonamalgam restorations in primary and permanent teeth according to age groups (2-5 years, 6-11 years, 12-15 years, 16-19 years, 20-39 years, 40-59 years, 60-79 years, and ≥ 80 years), race and ethnicity, federal poverty guideline, education, and pregnancy status. RESULTS: The prevalence of amalgam restorations ranged from 4% through 69%. Overall, amalgam restorations were more prevalent in children and adolescents from racial and ethnic minority groups and families at lower poverty levels and with lower education. The mean number of teeth with nonamalgam restorations was higher than those with amalgam restorations in primary teeth of children aged 6 through 11 years, permanent teeth of those 12 through 15 years and 20 through 39 years, and women aged 20 through 49 years, regardless of pregnancy status. The mean number of amalgam restorations was higher than that for nonamalgam restorations in older age groups. CONCLUSIONS: Nonamalgam restorations were the most common in the primary teeth of children older than 5 years and in the permanent teeth of adults younger than 40 years. Amalgam restorations were more common in older adults. Amalgam and nonamalgam restorations were equally common in children younger than 5 years. PRACTICAL IMPLICATIONS: The study findings suggest a shift from amalgam to alternative restorative materials in the United States.

Dental health status, use, and insurance coverage among adults with chronic conditions: Implications for medical-dental integration in the United States.

BACKGROUND: The authors examined potential benefits and difficulties in integrating oral health care and medical care for adults with chronic conditions (CCs). METHODS: The authors used National Health and Nutrition Examination Survey 2009-2016 data to estimate crude (age- and sex-standardized) and model-adjusted estimates to examine the association between dental disease (severe tooth loss, untreated caries) and chronic disease (≥ 3 CCs, fair or poor health) and Medical Expenditure Panel Survey 2014-2016 data to estimate crude estimates of past-year medical and dental use and financial access according to CC status. Reported differences are significant at P < .05. RESULTS: National prevalences of reporting fair or poor health and 3 or more CCs were both approximately 15%. Standardized prevalence of dental disease was notably higher among adults reporting CCs than those not reporting. After controlling for covariates, the magnitude of the association was substantially lower, although the association remained significant. Adults with CCs were approximately 50% more likely to report having a past-year medical visit and no dental visit than those not reporting CCs. Among adults reporting CCs, prevalence of having no private dental insurance and low income was approximately 20% and 60% higher, respectively, than that among adults not reporting CCs. CONCLUSIONS: Adults with CCs had higher prevalence of dental disease, past-year medical visit and no dental visit, and limited financial access. PRACTICAL IMPLICATIONS: Medical visits may be the only opportunity to provide dental education and referrals to adults with CCs. Improved medical-dental integration could improve oral health care access and oral health among these adults who are at higher risk of dental disease.

Untreated caries among US working-aged adults and association with reporting need for oral health care.

BACKGROUND: National data indicate that working-aged adults (20-64 years) are more likely to report financial barriers to receiving needed oral health care relative to other age groups. The aim of this study was to examine the burden of untreated caries (UC) and its association with reporting an unmet oral health care need among working-aged adults. METHODS: The authors used National Health and Nutrition Examination Survey data from 2011 through 2016 for 10,286 dentate adults to examine the prevalence of mild to moderate (1-3 affected teeth) and severe (≥ 4 affected teeth) UC. The authors used multivariable logistic regression to identify factors that were associated with reporting an unmet oral health care need. RESULTS: Low-income adults had mild to moderate UC (26.2%) 2 times more frequently and severe UC (13.2%) 3 times more frequently than higher-income adults. After controlling for covariates, the variables most strongly associated with reporting an unmet oral health care need were UC, low income, fair or poor general health, smoking, and no private health insurance. The model-adjusted prevalence of reporting an unmet oral health care need among low-income adults with mild to moderate and severe UC were 35.7% and 45.1%, respectively. CONCLUSIONS: The burden of UC among low-income adults is high; prevalence was approximately 40% with approximately 3 affected teeth per person on average. Reporting an unmet oral health care need appears to be capturing primarily differences in UC, health, and financial access to oral health care. PRACTICAL IMPLICATIONS: Data on self-reported unmet oral health care need can have utility as a surveillance tool for monitoring UC and targeting resources to decrease UC among low-income adults.

The Impact of Dental Insurance and Medical Insurance on Dental Care Utilization During Pregnancy.

OBJECTIVE: To measure the association between dental and medical insurance with the receipt of dental cleaning during pregnancy. METHODS: We analyzed Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2012 to 2015 on 145,051 women with a recent live birth from 36 states. We used adjusted prevalence ratios [aPR] from multivariable regression to examine the association of dental and medical insurance with receipt of dental cleaning during pregnancy, controlling for selected covariates that influence dental care utilization. RESULTS: Seventy-seven percent (77%) of all women reported having dental insurance during pregnancy. Receipt of dental cleaning before pregnancy was strongly associated with dental cleaning during pregnancy. Among women without pre-pregnancy dental cleaning who had dental insurance, those with Medicaid medical insurance had a significantly higher prevalence of dental cleaning during pregnancy [aPR = 1.42, 95% CI (1.32 - 1.52)], compared to those private medical insurance. Among women without pre-pregnancy dental cleaning, those without dental insurance but with Medicaid medical insurance were about 70% less likely to have dental cleaning during pregnancy compared to those with dental and private medical insurance. CONCLUSIONS FOR PRACTICE: With or without dental insurance, pre-pregnancy dental cleaning was strongly associated with dental cleaning during pregnancy. Dental insurance was an important determinant of dental utilization. Medical insurance had an independent and positive effect. This effect varied by private versus Medicaid medical insurance. Programs which provide women with dental insurance both before and during pregnancy could improve the oral health of maternal and infant populations.

Public Health Aspects of Periodontitis: Recent Advances and Contributions by Dr. Robert J. Genco.

Purpose of review: This review provides an overview of the objectives, activities and accomplishments of the CDC-AAP collaboration on public health aspects of periodontitis focusing mostly on surveillance. Dr. Robert Genco was co-chair of this effort. Recent findings: This initiative developed new standard periodontitis case definitions for surveillance and implemented for the first time a full-mouth periodontal examination protocol for NHANES 2009 -2014. Measurements from this survey resulted in significantly greater estimate for the national prevalence of periodontitis in US adults and our understanding of population risk factors associations with periodontitis. Notably, this initiative also developed, and validated field-testing a battery of eight questions for multivariable modeling of self-report measures for predicting periodontitis in populations. Summary: This Initiative resulted in significant improvements of surveillance of periodontitis and produced unique findings with important implications for advancing our understanding of population aspects of periodontitis in US adults at the national, state, and local levels.

Prevalence of and Changes in Tooth Loss Among Adults Aged ≥50 Years with Selected Chronic Conditions - United States, 1999-2004 and 2011-2016.

Extensive tooth loss can lead to poor diet resulting in weight loss or obesity (1). It can also detract from physical appearance and impede speech, factors that can restrict social contact, inhibit intimacy, and lower self-esteem (1). Chronic medical conditions and oral conditions share common risk factors (2). Persons with chronic conditions are more likely to have untreated dental disease, which can result in tooth loss. Three measures of tooth loss during 1999-2004 and 2011-2016 were estimated by comparing data from the National Health and Nutrition Examination Survey (NHANES) for each period among adults aged ≥50 years with selected chronic conditions.* The three measures were 1) edentulism (having no teeth); 2) severe tooth loss (having eight or fewer teeth) (3); and 3) lacking functional dentition (having <20 teeth out of 28, which is considered a full set for the purpose of NHANES assessments) (4). During 2011-2016, prevalences of edentulism and severe tooth loss were ≥50% higher among adults with fair or poor general health, rheumatoid arthritis, asthma, diabetes, emphysema, heart disease, liver condition, or stroke than among those with those adults without the chronic condition. Lack of functional dentition was also more prevalent among adults with chronic conditions than among persons without these conditions. Tooth loss is preventable with self-care and routine dental visits (1). To encourage these behaviors, public health professionals can educate the public about the association between having a chronic condition and tooth loss, and primary care providers can educate their patients about the importance of healthy behaviors and screen and refer them for needed dental care.

Overview and quality assurance for the oral health component of the National Health and Nutrition Examination Survey (NHANES), 2011-2014.

BACKGROUND: Following implementation in 2009-2010 to the oral health component for the National Health and Nutrition Examination Survey (NHANES), a full-mouth periodontal examination was continued during 2011-2014. Additionally, a comprehensive dental caries assessment was re-introduced in 2011 after a 6-year absence from NHANES. This report provides oral health content information and results of dental examiner reliability statistics for key intraoral assessments conducted by dentists during 2011-2014. METHODS: During the 2011-2014 NHANES 17,463 persons age 1 and older representing the US civilian, non-institutionalized population received an oral health examination. From this group, 387 individuals underwent a repeat examination conducted by the survey reference examiner. A combination of examiner training and calibration, electronic data capture, and ongoing performance evaluation with statistical monitoring was used to ensure conformance with NHANES protocols and data comparability to prior data collection periods. RESULTS: During 2011-2014, the Kappa statistics for the tooth count assessment ranged from 0.96 to 1.00, for untreated dental caries Kappa scores were 0.93 to 1.00. The overall Kappa statistics for identifying combined moderate-severe periodontitis using the CDC/AAP case definition was 0.66 and 0.69 with percent agreement of 83 to 85% during 2011-2014. When evaluating inter-examiner agreement using information collected from 3 periodontal sites for comparability to the NHANES 2003-04 periodontal examination protocols, Kappa scores for combined moderate-severe periodontitis was 0.65 and 0.80 during 2011-2014. For total mean attachment loss and pocket depth across all 6 periodontal sites, the inter-class coefficients (ICCs) ranged from 0.80-0.90 and 0.79-0.86 respectively. Site-specific mean attachment loss ICCs were generally higher for the 4 interproximal measurements compared to the 2 mid-site probing measurements and this observation was similar in 2009-2010. CONCLUSION: During 2011-2014, results overall indicate a high level of data quality and substantial examiner reliability for tooth count and dentition; reliability for periodontal disease, across various assessments, was at least moderate. When comparing the 2011-2014 examiner performance to findings from 2003 to 2004, comparable concordance between the examiners and the reference examiner exists.

Use of Toothpaste and Toothbrushing Patterns Among Children and Adolescents - United States, 2013-2016.

Fluoride use is one of the main factors responsible for the decline in prevalence and severity of dental caries and cavities (tooth decay) in the United States (1). Brushing children's teeth is recommended when the first tooth erupts, as early as 6 months, and the first dental visit should occur no later than age 1 year (2-4). However, ingestion of too much fluoride while teeth are developing can result in visibly detectable changes in enamel structure such as discoloration and pitting (dental fluorosis) (1). Therefore, CDC recommends that children begin using fluoride toothpaste at age 2 years. Children aged <3 years should use a smear the size of a rice grain, and children aged >3 years should use no more than a pea-sized amount (0.25 g) until age 6 years, by which time the swallowing reflex has developed sufficiently to prevent inadvertent ingestion. Questions on toothbrushing practices and toothpaste use among children and adolescents were included in the questionnaire component of the National Health and Nutrition Examination Survey (NHANES) for the first time beginning in the 2013-2014 cycle. This study estimates patterns of toothbrushing and toothpaste use among children and adolescents by analyzing parents' or caregivers' responses to questions about when the child started to brush teeth, age the child started to use toothpaste, frequency of toothbrushing each day, and amount of toothpaste currently used or used at time of survey. Analysis of 2013-2016 data found that >38% of children aged 3-6 years used more toothpaste than that recommended by CDC and other professional organizations. In addition, nearly 80% of children aged 3-15 years started brushing later than recommended. Parents and caregivers can play a role in ensuring that children are brushing often enough and using the recommended amount of toothpaste.

Geospatial distribution of periodontists and US adults with severe periodontitis.

BACKGROUND: In this study, the authors report on the geospatial distributions of periodontists and adults with severe periodontitis in the United States. METHODS: The authors used geospatial analysis to describe the distribution of periodontists and adults, periodontists vis-à-vis estimated density of adults with severe periodontitis, and their ratios to adults with severe periodontitis. The authors identified locations of 5,415 practicing periodontists through the 2014 National Provider Identifier Registry, linked them with the weighted census number of adults, and estimated the number of adults within a series of circular distance zones. RESULTS: Approximately 60% of adults 30 through 79 years lived within 5 miles of a periodontist, 73% within 10 miles, 85% within 20 miles, and 97% within 50 miles. Proximity to a periodontist varied widely. In urban areas, 95% of adults resided within 10 miles of a periodontist and 100% within 20 miles. Only 24% of adults in rural areas lived within 10 miles of a periodontist. Most periodontists (96.1%) practiced in urban areas, clustering along the eastern and western coasts and in the Midwest, 3.1% in urban clusters elsewhere, and 0.8% in rural areas. Ratios of fewer than 8,000 adults with periodontitis to 1 or more periodontists within 10 miles were clustered mostly in the Northeast, central East Coast, Florida, West Coast, Arizona, and Midwest. CONCLUSIONS: In this study, the authors identified wide variations in geographic proximity to a practicing periodontist for adults with severe periodontitis. PRACTICAL IMPLICATIONS: Dental practitioners may provide preventive care and counseling for periodontitis and referrals for specialty care. Geographic proximity to specialized periodontal care may vary widely by locality.

Periodontitis in US Adults: National Health and Nutrition Examination Survey 2009-2014.

BACKGROUND: This report presents weighted average estimates of the prevalence of periodontitis in the adult US population during the 6 years 2009-2014 and highlights key findings of a national periodontitis surveillance project. METHODS: Estimates were derived for dentate adults 30 years or older from the civilian noninstitutionalized population whose periodontitis status was assessed by means of a full-mouth periodontal examination at 6 sites per tooth on all non-third molar teeth. Results are reported according to a standard format by applying the Centers for Disease Control and Prevention/American Academy of Periodontology periodontitis case definitions for surveillance, as well as various thresholds of clinical attachment loss and periodontal probing depth. RESULTS: An estimated 42% of dentate US adults 30 years or older had periodontitis, with 7.8% having severe periodontitis. Overall, 3.3% of all periodontally probed sites (9.1% of all teeth) had periodontal probing depth of 4 millimeters or greater, and 19.0% of sites (37.1% of teeth) had clinical attachment loss of 3 mm or greater. Severe periodontitis was most prevalent among adults 65 years or older, Mexican Americans, non-Hispanic blacks, and smokers. CONCLUSIONS: This nationally representative study shows that periodontitis is a highly prevalent oral disease among US adults. PRACTICAL IMPLICATIONS: Dental practitioners should be aware of the high prevalence of periodontitis in US adults and may provide preventive care and counselling for periodontitis. General dentists who encounter patients with periodontitis may refer these patients to see a periodontist for specialty care.

Periodontitis prevalence in adults ≥ 65 years of age, in the USA.

The older adult population is growing rapidly in the USA and it is expected that by 2040 the number of adults ≥ 65 years of age will have increased by about 50%. With the growth of this subpopulation, oral health status, and periodontal status in particular, becomes important in the quest to maintain an adequate quality of life. Poor oral health can have a major impact, leading to tooth loss, pain and discomfort, and may prevent older adults from chewing food properly, often leading to poor nutrition. Periodontitis is monitored in the USA at the national level as part of the Healthy People 2020 initiative. In this report, we provide estimates of the overall burden of periodontitis among adults ≥ 65 years of age and after stratification according to sociodemographic factors, modifiable risk factors (such as smoking status), the presence of other systemic conditions (such as diabetes) and access to dental care. We also estimated the burden of periodontitis within this age group at the state and local levels. Data from the National Health and Nutrition Examination Survey 2009/2010 and 2011/2012 cycles were analyzed. Periodontal measures from both survey cycles were based on a full-mouth periodontal examination. Nineteen per cent of adults in this subpopulation were edentulous. The mean age was 73 years, 7% were current smokers, 8% lived below the 100% Federal Poverty Level and < 40% had seen a dentist in the past year. Almost two-thirds (62.3%) had one or more sites with ≥ 5 mm of clinical attachment loss and almost half had at least one site with probing pocket depth of ≥ 4 mm. We estimated the lowest prevalence of periodontitis in Utah (62.3%) and New Hampshire (62.6%) and the highest in New Mexico, Hawaii, and the District of Columbia each with a prevalence of higher than 70%. Overall, periodontitis is highly prevalent in this subpopulation, with two-thirds of dentate older adults affected at any geographic level. These findings provide an opportunity to determine how the overall health-care management of older adults should consider the improvement of their oral health conditions. Many older adults do not have dental insurance and are also likely to have some chronic conditions, which can adversely affect their oral health.

Risk Indicators for Periodontitis in US Adults: NHANES 2009 to 2012.

BACKGROUND: Through the use of optimal surveillance measures and standard case definitions, it is now possible to more accurately determine population-average risk profiles for severe (SP) and non-severe periodontitis (NSP) in adults (aged 30 years and older) in the United States. METHODS: Data from the 2009 to 2012 National Health and Nutrition Examination Survey were used, which, for the first time, used the "gold standard" full-mouth periodontitis surveillance protocol to classify severity of periodontitis following suggested Centers for Disease Control/American Academy of Periodontology case definitions. Probabilities of periodontitis by: 1) sociodemographics, 2) behavioral factors, and 3) comorbid conditions were assessed using prevalence ratios (PRs) estimated by predicted marginal probability from multivariable generalized logistic regression models. Analyses were further stratified by sex for each classification of periodontitis. RESULTS: Likelihood of total periodontitis (TP) increased with age for overall and NSP relative to non-periodontitis. Compared with non-Hispanic whites, TP was more likely in Hispanics (adjusted [a]PR = 1.38; 95% confidence interval 95% CI: 1.26 to 1.52) and non-Hispanic blacks (aPR = 1.35; 95% CI: 1.22 to 1.50), whereas SP was most likely in non-Hispanic blacks (aPR = 1.82; 95% CI: 1.44 to 2.31). There was at least a 50% greater likelihood of TP in current smokers compared with non-smokers. In males, likelihood of TP in adults aged 65 years and older was greater (aPR = 2.07; 95% CI: 1.76 to 2.43) than adults aged 30 to 44 years. This probability was even greater in women (aPR = 3.15; 95% CI: 2.63 to 3.77). Likelihood of TP was higher in current smokers relative to non-smokers regardless of sex and periodontitis classification. TP was more likely in men with uncontrolled diabetes mellitus (DM) compared with adults without DM. CONCLUSIONS: Assessment of risk profiles for periodontitis in adults in the United States based on gold standard periodontal measures show important differences by severity of disease and sex. Cigarette smoking, specifically current smoking, remains an important modifiable risk for all levels of periodontitis severity. Higher likelihood of TP in older adults and in males with uncontrolled DM is noteworthy. These findings could improve identification of target populations for effective public health interventions to improve periodontal health of adults in the United States.

Dental caries and sealant prevalence in children and adolescents in the United States, 2011-2012.

Although dental caries has been declining in permanent teeth for many children since the 1960s, previous findings showed caries in primary teeth for preschool children increasing from 24% to 28% between 1988 and 2004. Disparities in caries continue to persist for some race and ethnic groups in the United States. Prevalence of dental sealants--applied to the tooth chewing surfaces to help prevent caries--has also varied among sociodemographic groups. This report describes U.S. youth dental caries and sealant prevalence by race and Hispanic origin for 2011-2012.

Dental caries and tooth loss in adults in the United States, 2011-2012.

KEY FINDINGS: Among adults aged 20-64, 91% had dental caries and 27% had untreated tooth decay. Untreated tooth decay was higher for Hispanic (36%) and non-Hispanic black (42%) adults compared with non-Hispanic white (22%) and non-Hispanic Asian (17%) adults aged 20-64. Adults aged 20-39 were twice as likely to have all their teeth (67%) compared with those aged 40-64 (34%). About one in five adults aged 65 and over had untreated tooth decay. Among adults aged 65 and over, complete tooth loss was lower for older Hispanic (15%) and non-Hispanic white (17%) adults compared with older non-Hispanic black adults (29%).

Update on Prevalence of Periodontitis in Adults in the United States: NHANES 2009 to 2012.

BACKGROUND: This report describes prevalence, severity, and extent of periodontitis in the US adult population using combined data from the 2009 to 2010 and 2011 to 2012 cycles of the National Health and Nutrition Examination Survey (NHANES). METHODS: Estimates were derived for dentate adults, aged ≥30 years, from the US civilian non-institutionalized population. Periodontitis was defined by combinations of clinical attachment loss (AL) and periodontal probing depth (PD) from six sites per tooth on all teeth, except third molars, using standard surveillance case definitions. For the first time in NHANES history, sufficient numbers of non-Hispanic Asians were sampled in 2011 to 2012 to provide reliable estimates of their periodontitis prevalence. RESULTS: In 2009 to 2012, 46% of US adults, representing 64.7 million people, had periodontitis, with 8.9% having severe periodontitis. Overall, 3.8% of all periodontal sites (10.6% of all teeth) had PD ≥4 mm, and 19.3% of sites (37.4% teeth) had AL ≥3 mm. Periodontitis prevalence was positively associated with increasing age and was higher among males. Periodontitis prevalence was highest in Hispanics (63.5%) and non-Hispanic blacks (59.1%), followed by non-Hispanic Asian Americans (50.0%), and lowest in non-Hispanic whites (40.8%). Prevalence varied two-fold between the lowest and highest levels of socioeconomic status, whether defined by poverty or education. CONCLUSIONS: This study confirms a high prevalence of periodontitis in US adults aged ≥30 years, with almost fifty-percent affected. The prevalence was greater in non-Hispanic Asians than non-Hispanic whites, although lower than other minorities. The distribution provides valuable information for population-based action to prevent or manage periodontitis in US adults.

Periodontitis among adults aged ≥30 years - United States, 2009-2010.

Periodontal disease, or gum disease, is a chronic infection of the hard and soft tissue supporting the teeth and is a leading cause of tooth loss in older adults. Tooth loss impairs dental function and quality of life in older adults. The chronic infections associated with periodontitis can increase the risk for aspiration pneumonia in older adults and has been implicated in the pathogenesis of chronic inflammation that impairs general health. The severity of periodontal disease can be categorized as mild, moderate, or severe on the basis of multiple measurements of periodontal pocket depth, attachment loss, and gingival inflammation around teeth.

Recording and surveillance systems for periodontal diseases.

This paper describes tools used to measure periodontal diseases and the integration of these tools into surveillance systems. Tools to measure periodontal diseases at the surveillance level have focussed on current manifestations of disease (e.g. gingival inflammation) or disease sequelae (e.g. periodontal pocket depth or loss of attachment). All tools reviewed in this paper were developed based on the state of the science of the pathophysiology of periodontal disease at the time of their design and the need to provide valid and reliable measurements of the presence and severity of periodontal diseases. Therefore, some of these tools are no longer valid. Others, such as loss of periodontal attachment, are the current de-facto tools but demand many resources to undertake periodical assessment of the periodontal health of populations. Less complex tools such as the Community Periodontal Index, have been used extensively to report periodontal status. Laboratory tests for detecting putative microorganisms or inflammatory agents present in periodontal diseases have been used at the clinical level, and at least one has been tested at the population level. Other approaches, such as self-report measures, are currently under validation. In this paper, we do not review indices designed to measure plaque or residual accumulation around the tooth, indices focussed only on gingival inflammation or radiographic approaches with limited applicability in surveillance systems. Finally, we review current case-definitions proposed for surveillance of periodontal disease severity.
