Dental health of elderly confederate veterans: evidence from the Texas State Cemetery

Analysis of the skeletal remains of 50 Confederate veterans provided a unique opportunity to explore the dental health of a geriatric sample. These men, who died between 1907-1932, had an average age at death of 76.7 years. Ninety percent were institutionalized at the Confederate Home for Men (Austin, TX) prior to their deaths. This elderly sample was assessed in terms of caries, antemortem tooth loss (AMTL), abscesses, and linear enamel hypoplasias. On a per tooth basis, the AMTL rate was 57.2%. Of 39 dentate men, 33 (84.6%) had dental caries, and 24.4% (121 of 496) of teeth were carious. Ten (25.0%) of the dentate men had hypoplastic teeth. At least one abscess was seen in 14 (28%) of 50 individuals. Results from this geriatric institutionalized sample are compared to contemporaneous historical samples. Disparities in dental health among these groups may be due to differences in average age at death, and these comparisons allow a better understanding of dental changes that occur with age. The sample is also compared to modern elderly samples: modern groups have higher caries rates, possibly because they retained more teeth. This finding may be due in part to diets in the United States becoming increasingly cariogenic over time. In addition, dental care has moved from the reactive practices seen in the nineteenth and early twentieth centuries (such as tooth extractions) to modern proactive solutions dedicated to preserving and restoring teeth (such as tooth brushing, fluoride treatments, and dental fillings).     

Dental paleopathology and agricultural intensification in south Asia: new evidence from Bronze Age Harappa.

Patterns of dental disease among Bronze Age people of the Indus Valley Civilization are currently based on early and incomplete reports by non-specialists. This deficiency precludes accurate diachronic analysis of dental disease and its relationship with increasing agriculturalism in the Indian subcontinent. The objective of this paper is to document prevalence of dental disease at Harappa (2500-2000 B.C.), Punjab Province, Pakistan, comparatively evaluate the Harappan dental pathology profile, and use these data to assess theories regarding the dental health consequences of increasingly intensive agricultural dependence. Pathological conditions of the dentition included in the study are abscesses, ante-mortem tooth loss (AMTL), calculus, caries, hypoplasia, hypercementosis, pulp chamber exposure, and alveolar resorption. The Harappan dentition exhibits a dental pathology profile typical of a population whose subsistence base is agriculture. Dental caries at Harappa are present in 6.8% (n = 751) of the teeth and 43.6% (n = 39) of the more completely preserved dental specimens. The use of a caries correction factor is recommended to permit an estimate of caries induced AMTL in calculating the caries prevalence. All dental lesions are present at higher rates in this Harappan study sample than were reported in previous investigations, and important differences in prevalence of dental disease occur between the genders. Prevalence of dental disease increases in the greater Indus Valley as subsistence becomes more intensive and as food preparation and storage technology becomes more efficient.     

Continuity or discontinuity of the life-style in central Italy during the Roman Imperial Age-Early Middle Ages transition: diet, health, and behavior

Dento-alveolar pathologies and alterations (dental wear, caries, abscesses, ante mortem tooth loss (AMTL), calculus, hypoplastic defects, and chipping) and skeletal markers of health (cribra orbitalia and periostitis) were analyzed in two skeletal samples from the necropolises of Quadrella (I-IV c. AD) and Vicenne-Campochiaro (VII c. AD) in the Molise region of central Italy. The aim was to determine if the Roman Imperial Age-Early Middle Ages transition characterized by political, socioeconomic, and cultural transformations affected the biology of these populations, particularly their alimentation and health status. The frequencies of caries and AMTL, similar in the two samples, suggest a high consumption of carbohydrates. The higher levels of heavy wear, calculus, and interproximal chipping in the Vicenne population indicate a greater use of fibrous foods (both meat and others), in line with the dietary model of Germanic peoples. Health conditions do not appear to have been good in either period, as shown by the high frequencies of linear hypoplasia and the presence of cribra orbitalia and periostitis. The diet of the individuals buried with horses of the Vicenne population did not differ from that of the rest of the population, whereas there were evident differences in the use of the teeth for nonmasticatory activities among these individuals. Therefore, from the point of view of alimentation and health status, the profound socioeconomic and cultural transformations during the Late Antiquity-Early Middle Ages transition do not seem to have been translated into a true discontinuity of the two Molisan populations.     

Pattern of tooth loss in an elderly population from Ibadan, Nigeria

Objectives: To determine tooth loss, edentulousness, causes of tooth loss and pattern of tooth loss in the elderly in South East Local Government area (SELGA) in Ibadan. Background data: SELGA is one of the largest in Oyo State, Nigeria and has a population of 225 800. Design: A cross‐sectional survey. Methodology: A total of 690 elderly individuals who were 65 years and above living in various wards in SELGA were interviewed by two interviewers and examined by two trained and calibrated examiners whilst two record clerks recorded all the findings of the examination. Result: Forty‐eight per cent of the subjects in the study had not lost any teeth. The mean tooth loss was 4.5 ± 7.6. Percentage edentulousness was 1.3% and this was higher in males than in females. This difference was not statistically significant (χ² = 0.07 p = 0.7). The total number of teeth lost was 3102, 14% of the total number of teeth examined. The study showed that caries was not a major cause of tooth loss. Only 22 (0.7%) teeth were lost as a result of caries, 19 (0.6%) were lost because of trauma and periodontal disease contributed to loss of 3061 (98.7%) teeth. Mandibular teeth exhibited a higher rate of retention than maxillary teeth. The percentage of elderly individuals with tooth loss increased with age. Conclusion: The study highlights the high life expectancy of a tooth among the elderly in SELGA. Despite the different cause of tooth loss in this area, in comparison with developed countries, the pattern of tooth retention appeared similar.

本文对新疆吐鲁番市加依墓地青铜—早期铁器时代居民的牙齿磨耗、口腔疾病和骨质隆起等特征进行了观察与研究,结果显示,加依墓地居民的牙齿磨耗较重,但前后部牙齿的磨耗程度差异不大,臼齿偏斜式磨耗现象显著,龋齿罹患率偏低。生前脱落、牙结石等口腔疾病在该人群中普遍流行,部分个体的下颌存在发育显著的骨质隆起现象。本文还通过臼齿磨耗方向指数(Wear Orientation)对加依墓地居民的偏斜式磨耗进行了量化研究,并参考相关民族学调查、考古发现以及现代医学研究成果对加依墓地居民复杂的牙齿磨耗形态和口腔疾病的成因进行了初步探讨。推测加依墓地居民的食物结构应以肉类为主,谷类亦占有一定地位;此外可能是受到恶劣生活环境及特殊谷物加工技术的影响,日常食物较为坚硬。     

The usefulness of caries frequency,depth, and location in determining cariogenicity and past subsistence: A test on early and later agriculturalists from the Peruvian coast

Dental markers have been used to unravel particularities of paleodiet, subsistence, social structure, and health. This article aims to compare oral pathology among four pre‐Columbian groups with different degrees of agricultural and socio‐cultural development but comparable ecological conditions who lived on the coastal desert of Peru. Three of these groups are assigned to distinct phases of the Formative Period (2500–1 BC), a time critical for our understanding of the development of agriculture and social complexity. The fourth group corresponds to the Late Intermediate Period (1000–1470 AD), when agriculture had its apogee and society was highly stratified. In this study we test whether there is an increase (1) in the frequency of carious lesions and (2) in caries depth, and (3) if there is a shift from occlusal to extra‐occlusal caries locations with the development of agriculture. Therefore, we analyze the frequencies of carious lesions and antemortem tooth loss (AMTL), the caries distributions by age, sex, and type of tooth, as well as the tissues affected by, and the location of the carious lesions. Since there are no significant differences in the frequencies of carious lesions and AMTL between the groups, we reject hypothesis 1. In contrast, caries depth does increase, and caries location changes from occlusal to extra‐occlusal sites with agricultural development. However, we can only corroborate hypothesis 2 and 3 when taking into consideration dental wear. Thus, we recommend that caries depth and locations should be used with evaluations of dental wear to reconstruct subsistence in ancient populations.

Stomatological studies of the slavic cemetery at the Spandau Burgwall, Berlin.]

The dentition of a medieval population from the former Spandau Burgwall in Berlin was investigated with regard to caries and other abnormities of the teeth, the palate and the jaws. The caries frequency amounts to 7.9%, while 63.6% of the individuals had a caries dentition. The diminuation of the caries frequency from the juveniles to the 40--60 years old individuals depends on the high rate of loss of tooth during life. Probably, all teeth which have been lost during life can be evaluated as decayed teeth. X-ray pictures have shown that three sets of teeth have hypercementotic alterations at the roots, eight permanent dentitions have cysts and apical parodontitis. Supernumerary cuspids at the toothcrowns are to be seen as a tuberculum paramolare and a tuberculum intermedium. A second upper molar has a reduced crown with only two cuspids and shows the tendency of reduction to a bicuspid. Toothrotation and other deviations of teeth from their position in the row are frequent in this material. Four deciduous dentitions of children were investigated, too. Three carious teeth were found among 45 available teeth, two deciduous molars and one first upper molar show a Carabelli's tubercle, the other first molar has a fovea carabelli.     

A new correction procedure for calibrating dental caries frequency

The incisors and canines and the premolars and molars show differential resistance to cariogenic factors. The anterior teeth have a lower caries frequency than the posterior teeth. However, these tooth classes are lost differentially in postmortem stages due to their anatomical structures. This differential postmortem tooth loss distorts proportions between the anterior and posterior tooth classes. The disproportionality can affect the calculation of total caries prevalence. In this paper, we propose a new calibration procedure which removes this disproportionality and call it the proportional correction factor. For this procedure, the caries rates of anterior and posterior teeth are corrected by multiplying the anterior teeth by three-eighths and the posterior teeth by five-eighths. These fractions are derived from the human dental formula which contains three anterior and five posterior teeth by side. The correction factor is more effective if the proportion of anterior to the posterior teeth is extremely distorted. When this procedure is used with the caries correction factor, it provides a useful way to approach to an almost true caries prevalence.

Paleodontologic study of skeletal findings at Takht-i Suleiman, West Iran

Within this paleodontological study 26 Achemenid and 8 Islamic skeletons from the excavations at Tahkt-i Suleiman (Western Iran) were investigated. The diagnosis of age and sex was done repeatedly according to various methods. The adult Achemenids reached an average age of 54.4 years (n = 16; SD = +/- 9.9 y), while the Islamic adult individuals reached a lifespan of 36.9 (n = 8; SD = +/- 11.0 y). The skeletons of the Achemenid children had an average of 6.8 years (n = 9; SD = +/- 3.3 y). In the specific dental investigations the teeth of all skeletons were checked for missing teeth or dental diseases or alterations of the jaws. For the whole series intravital loss of 19.3% of the teeth was found. 21.6% of the teeth were lost postmortally. The intravital loss of single teeth was 21.9% in the Achemenid teeth, disregarding the wisdom tooth and Dentes decidui; the respective value was 12% in the Islamic skeletons. The investigation for caries yielded a morbidity of 50% in the Achemenid skeletons, and 57% in the Islamic teeth. The frequency of caries was 6.2% in Achemenids and 9% in Islamic individuals. In the Dentes decidui the frequency of caries was found to be 3.6%. Dental tartar was present in 44.8% of the teeth, 42% of Achemenid teeth and 58% of Islamic teeth being affected. 33% of all teeth showed garlands of dental tartar. Signs of parodontolysis were investigated considering the health of the individual and the preservation of the skeleton. All adult teeth showed age-dependent parodontolysis, the means of which were quantified.     

Dental caries and antemortem tooth loss in the Northern Peten area,Mexico: a biocultural perspective on social status differences among the Classic Maya

Dental caries and antemortem tooth loss (AMTL) are investigated in a Classic Maya sample obtained from the sites of Calakmul, Dzibanché, and Kohunlich (Mexico). This study aims at assessing the effect that sex and social status had on the prevalence of oral pathologies. The lack of a direct relationship between caries, AMTL, and age-at-death led us to interpret the results in terms of the biological, socioeconomic, and behavioral conditions prevailing in these ancient Maya settlements. Benefits related to sex and social status are evident in the frequency of carious lesions, which appear less frequently in elite males than in low-status individuals of both sexes and in elite females. Individuals from problematic mortuary contexts and isolated bone assemblages, who could not be ascribed to any status group, showed the highest rates of caries. Sex discrimination in dietary preferences appears in the elite sample, while the homogeneity encountered between sexes in the low-status segment suggests a more uniform access to resources. Tooth loss clearly distinguishes elite individuals from commoners, regardless of sex, with the former bearing a much higher rate of loss. In individuals from the undefined mortuary assemblages and sacrificial contexts, it was even more pronounced than in the other groups, although its interpretation is problematic due to a lack of associated funerary data. The overall evidence from oral pathologies is interpreted to be the result of deficient oral hygiene coupled with a softer and more refined diet in the high-status population, particularly males. Whereas elite males' subsistence was apparently based more on animal proteins and relatively soft and refined foods, a diet relying on carbohydrates may account for the observed rate of oral pathologies in elite females and commoners.     

Periodontal disease in the Mycenean (1450–1150 BC) population of Aghia Triada, W. Peloponnese, Greece

This study investigates the incidence of periodontitis in a Mycenaean population unearthed at the cemetery of Aghia Triada (West Peloponnese, Greece) during the 1989–1997 field season. The material consists of 172 dry skulls. Demographic parameters of sex and age were difficult to be assigned due to the bad state of preservation of the skeletal material. The ratio was 50 males, 48 females, 65 unidentified and 9 children, and we estimated an average age of 38 years. In this work we used traditional and modern methods to determine the incidence of periodontitis in the archeological human dental bone. We also recorded other dental diseases, such as ante mortem tooth loss, caries and attrition. The results showed that periodontitis has affected 35% of the jaws. A notable percentage of the individuals — 24% — lost three or more teeth during their lifetime and a total 53% of the population had extracted teeth before death. This paper points out that the ancient jaws present a high proportion of ante-mortem tooth loss, attrition and deep caries, whereas the frequency of periodontitis does not seem to differ from that of other prehistoric samples.     

Severe wear and tooth loss in wild ring-tailed lemurs (Lemur catta): a function of feeding ecology, dental structure, and individual life history

The ring-tailed lemurs at Beza Mahafaly Special Reserve, Madagascar, exhibit a high frequency of severe wear and antemortem tooth loss. As part of a long-term study, we collected dental data on 83 living adult ring-tailed lemurs during 2003 and 2004. Among these individuals, 192 teeth were scored as absent. The most frequently missing tooth position is M1 (24%). As M1 is the first tooth to erupt, its high frequency of absence (primarily a result of wear) is not remarkable. However, the remaining pattern of tooth loss does not correlate with the sequence of eruption. We suggest that this pattern is a function of 1) feeding ecology, as hard, tough tamarind fruit is a key fallback food of ring-tailed lemurs living in gallery forests; 2) food processing, as tamarind fruit is primarily processed in the P3-M1 region of the mouth; and 3) tooth structure, as ring-tailed lemurs possess thin dental enamel. The incongruity between thin enamel and use of a hard, tough fallback food suggests that ring-tailed lemurs living in riverine gallery forests may rely on resources not used in the past. When comparing dental health in the same individuals (n=50) between 2003 and 2004, we found that individual tooth loss can show a rapid increase over the span of one year, increasing by as much as 20%. Despite this rapid loss, individuals are able to survive, sometimes benefiting from unintentional assistance from conspecifics, from which partially processed tamarind fruit is obtained. Although less frequent in this population, these longitudinal data also illustrate that ring-tailed lemurs lose teeth due to damage and disease, similar to other nonhuman primates. The relationship between tooth loss, feeding ecology, dental structure, and individual life history in this population has implications for interpreting behavior based on tooth loss in the hominid fossil record.     

Incidence of caries and abscesses in archeological Eskimo skeletal samples from point hope and Kodiak Island,Alaska

The incidence of caries and abscesses in 246 archeologically derived skeletal specimens from the Ipiutak and Tigara levels at Point Hope, Alaska, and 79 specimens excavated from Jones Point, Kodiak Island, Alaska were investigated. All three collections span long periods of time. Only pre-white contact specimens were used. Each specimens was sexed and aged in five year groupings, using standard techniques. Caries and abscesses were recorded by type and degree of severity and correlated with age, sex, and site of origin. All samples displayed very low caries rates and few abscesses per tooth and per individual (both observed frequencies, and frequencies corrected for postmortem loss of teeth). DMF scores were tabulated using both observed and corrected frequencies. Very heavy occlusal wear in all three samples could account for the majority of abscesses and pulp exposures, while the low caries rates are attributable to traditional diets totally devoid of refined sugars, starches, and food additives.     

The reasons for tooth loss in geriatric patients attending two surgical clinics in Jerusalem,Israel.

Abstract Objectives Numerous studies around the world have been conducted in order to understand the reasons for tooth extractions in various age groups. Most studies have dealt with the general adult population but little attention has been paid to the elderly population. In Israel, as in most of the western countries, the elderly population is growing rapidly and thus demands for its dental needs are also increasing. In order to meet the dental requirements of the geriatric population, data on the main reasons of tooth mortality have been collected. Design Retrospective analysis of reasons for extraction divided into three categories: caries, periodontal disease and “other’’. Subjects The files of 302 consecutive elderly patients aged 65-95 years attending for extraction. The cause for tooth extraction was gathered from the written diagnosis described by the operator as well as from radiographs. Setting Two surgical clinics in Jerusalem serving low income residents. Results Results indicated that 30% of the extractions were due to caries, 65% were due to periodontal disease and only 6.4% related to “other’’ reasons. In both, males and females, periodontal disease was the major cause for tooth loss yet, females exhibited more extractions due to caries than males (35%vs 23% respectively). A relatively high incidence of tooth loss was documented for the 85+ age group. Of the teeth that were extracted, incisors and molars were equally the most frequent (29%) followed by premolars (26%) and canines (17%). Premolars were the teeth most frequently extracted out of the teeth removed due to caries (32%) whereas incisors were the most frequently removed within the group of teeth extracted due to periodontal disease (31%). Conclusions The results of this study point to the importance of prevention and treatment of dental diseases, particularly periodontal disease, in adults aged 0 years and above in order to prevent tooth loss in their later years.     

Tooth wear and dental pathology at the advent of agriculture: new evidence from the Levant

Differences in patterns of diet and subsistence through the analysis of dental pathology and tooth wear were studied in skeletal populations of Natufian hunter-gatherers (10,500-8300 BC) and Neolithic populations (8300-5500 BC, noncalibrated) from the southern Levant. 1,160 Natufians and 804 Neolithic teeth were examined for rate of attrition, caries, antemortem tooth loss, calculus, periapical lesions, and periodontal processes. While the Natufian people manifest a higher rate of dental attrition and periodontal disease (36.4% vs. 19%), Neolithic people show a higher rate of calculus. Both populations manifested low and similar rates of caries (6.4% in the Natufian vs. 6.7% in the Neolithic), periapical lesions (not over 1.5%), and antemortem tooth loss (3.7% vs. 4.5%, respectively). Molar wear pattern in the Neolithic is different than in the Natufian. The current study shows that the dental picture obtained from the two populations is multifactorial in nature, and not exclusively of dietary origin, i.e., the higher rate and unique pattern of attrition seen in the Natufian could result from a greater consumption of fibrous plants, the use of pestles and mortars (which introduce large quantities of stone-dust to the food), and/or the use of teeth as a "third hand." The two major conclusions of this study are: 1) The transition from hunting and gathering to a food-producing economy in the Levant did not promote changes in dental health, as previously believed. This generally indicates that the Natufians and Neolithic people of the Levant may have differed in their ecosystem management (i.e., gathering vs. growing grains), but not in the type of food consumed. 2) Changes in food-preparation techniques and nondietary usage of the teeth explain much of the variation in tooth condition in populations before and after the agricultural revolution.     

Relative contribution of caries and periodontal disease in adult tooth loss among patients reporting to the Institute of Dental Sciences,Belgaum, India

Objectives: To examine the reasons for tooth loss in an adult population. Methods: Patients who reported to the department of prosthodontics in Institute of Dental Sciences, Belgaum, located in the north‐western part of the state of Karnataka, in the southern region of India over a period of 2 months, with at least one missing tooth (excluding third molars) constituted the sample size. There were a total of 365 patients (185 females and 180 males) within the age group of 16–84 years (mean age 51.06 ± 16.47 years) who fulfilled this criterion. Socio‐demographic profile was recorded along with a clinical examination for assessing the number and pattern of tooth loss. The reasons for tooth loss were recorded according to the history reported by the patient. Results: In the present study of 365 patients, 58.9% of the patients were completely edentulous, 41% were partially dentate, of which 20.8% had lost their teeth from caries, 11% from periodontal disease and 9.3% from a combination of reasons. More females had lost their teeth because of dental caries whereas more males had lost their teeth because of periodontal disease, this being statistically significant. (χ² = 16.53, p = 0.001). Highly significant results were obtained for age and reasons for tooth loss. (χ² = 150.39, p < 0.001). Irrespective of the socio‐economic status, dental caries was the most common cause for tooth loss in partially dentate patients though it was not statistically significant (χ² = 13.62, p = 0.325). Mandibular first molars were the teeth most frequently lost due to dental caries. The maxillary left central incisor was most frequently lost due to periodontal disease, followed by the maxillary right central incisor. Conclusions: Since both dental caries and periodontal disease contributed to tooth loss at different ages, risk indicators need to be identified.     

广西敢造遗址史前居民口腔的健康状况

广西扶绥敢造遗址是华南新石器时代一处典型的河岸贝丘遗址,其人骨测年结果的上限为8488 BC,下限为6492 BC。本文对敢造遗址2014年出土的108例个体的999枚恒齿进行观察统计,结果显示居民的饮食结构应是以肉食为主并辅以富含淀粉的块茎类植物。该遗址居民的龋齿率高于部分农业人群,但远低于同为华南渔猎—采集经济的鲤鱼墩、甑皮岩和顶蛳山遗址,其原因应与食用块茎类植物的多寡有关。较高的牙结石罹患率(89.86%)可能与鱼类、贝类等高蛋白饮食有关。相比农业、游牧或狩猎人群,该遗址居民偏重的牙齿磨耗可能与食用含沙量较大的螺类、贝类等有关;肉类食物的食用导致该遗址居民上颌前部牙齿磨耗重于后部牙齿,而“上颌前部牙齿舌侧过度磨耗”现象的出现则与食用块茎类植物有关。     

湖北郧县青龙泉新石器时代居民牙齿磨耗及健康状况

位于湖北省郧县境内的青龙泉遗址出土有仰韶、屈家岭和石家河等不同文化类型遗存, 被认为是中国新石器时代南、北文化交流的过渡地带。有关学者通过考古发现和同位素测试分析认为, 生活在青龙泉遗址的新石器时代居民已经具有发达的农业、家畜饲养业和渔猎,稻粟农业和肉类对居民的食物构成都有贡献, 但并不确定农业或渔猎是否占主导地位。本文通过对87例个体1075枚青龙泉新石器时代居民牙齿的磨耗、龋齿病、牙齿生前脱落、颌骨粗壮程度的观察、分析和对比, 试图从另一个侧面提供当时居民食物构成和经济模式的信息。本研究发现, 相比于其他中国新石器时代人类, 青龙泉居民的牙齿磨耗程度总体偏轻、臼齿磨耗角度多呈倾斜状、龋齿病出现率高、与生活状态相关的牙齿生前脱落出现率低、颌骨粗壮程度不明显。这些发现提示居民的食物较精细,加工程度高, 富含碳水化合物。基于本文发现, 作者认为农业经济在距今5000年左右的长江中游地区已经比较发达, 在居民食物构成中居主导地位,居民可能已经具有较高的食物制作加工技术。

Oral health status in elders from South Brazil: a population-based study

doi: 10.1111/j.1741‐2358.2011.00617.x Oral health status in elders from South Brazil: a population‐based study Objective: To assess the oral health status of community‐dwelling adults aged 60 years and older from southern Brazil and to determine demographics, socioeconomic, behavioural and dental risk indicators. Materials and methods: This cross‐sectional study used a multistage, probability sampling method to draw a representative sample of the metropolitan area of Porto Alegre, Brazil. A subsample of 217 subjects was included in this analysis. Oral mucosal lesions, dental caries, tooth loss and periodontal status (full‐mouth, six sites per tooth exam) were assessed by calibrated examiners. Results: Prevalence of edentulism was 39.5%, and mean tooth loss was 20.2 (SE = 0.6). Older individuals [Odds Ratio (OR) = 2.2], women (OR = 2.3), white people (OR = 5.9), individuals of lower socioeconomic status (OR = 5.6) and smokers (OR = 3.5) had higher likelihood of being edentulous. Approximately 36% of dentate individuals had caries and/or restoration affecting, in average, 5.0 teeth. Periodontitis affected 79% of subjects, and it was associated with older age (OR = 4.0), men (OR = 3.4) and large amounts of supragingival plaque (OR = 3.0). Conclusion: Poor oral health was observed in this elderly population from South Brazil. Sociodemographic disparities accounted for most of the burden of disease and treatment needs.
