Introduction</title><p>Dental caries is a disease with both high prevalence and severity in adult worldwide populations. Dental caries affects over half of the population in industrialized countries and since it is a cumulative process, the number of affected individuals increases with ageing [<xref rid="B1" ref-type="bibr">1</xref>–<xref rid="B4" ref-type="bibr">4</xref>]. Several studies show that dental caries in adult populations affects 5 to 10 teeth per individual, being the most significant cause of tooth loss among adults [<xref rid="B5" ref-type="bibr">5</xref>–<xref rid="B8" ref-type="bibr">8</xref>]. The damage caused by caries leads to a decrease in quality of life of affected individuals and high economic costs for both individuals and society, which turns this disease into an important public health problem [<xref rid="B5" ref-type="bibr">5</xref>–<xref rid="B8" ref-type="bibr">8</xref>].</p><p>According to the World Health Organization (WHO), chronic diseases associated to poor oral health are increasing in developing countries. More specifically, higher levels of edentulousness, caries and periodontal diseases are mentioned [<xref rid="B3" ref-type="bibr">3</xref>]. </p><p>WHO recommends epidemiological studies on population aged 35–44 and 65–74 due to the importance of these age groups in describing and analysing the cumulative damage of caries on people's oral health over the years [<xref rid="B9" ref-type="bibr">9</xref>, <xref rid="B10" ref-type="bibr">10</xref>].</p><p>Assessing oral health status in these population groups is important to gather relevant information for planning dental care services and also to generate evidence on final outcomes from dental care delivered to people during their entire life cycle [<xref rid="B8" ref-type="bibr">8</xref>, <xref rid="B11" ref-type="bibr">11</xref>, <xref rid="B12" ref-type="bibr">12</xref>]. </p><p>In Chile, before the First Chilean National Dental Examination, no previous study included examination by dentists to measure prevalence of caries or tooth loss in adults. Therefore, the resources that are needed to treat affected people remain unknown. Data collected in this study may be useful to build a more complete profile of oral health conditions of the adult population of South America and be a complement to the analysis of global trends of the disease.</p><p>The objective of this study is to determine the prevalence of caries and tooth loss among Chilean adult population aged 35–44 and 65–74 years old, using data from the First Chilean National Dental Examination Survey and to identify risk factors associated with tooth loss.</p></sec><sec id="sec2"><title>2. Material and Methods</title><sec id="sec2.1"><title>2.1. Sampling and Sample Sizes</title><p>The study population was gathered through the First Chilean National Dental Examination Survey and comprised noninstitutionalized adults aged 35–44 and seniors aged 65–74 years. All individuals lived in one of the 15 administrative regions of Chile, which in turn, constituted a cluster random sample based on region (in this study, the sample only considered urban population). The random sample included 1553 individuals, 1088 adults and 465 seniors, corresponding to age distribution of the Chilean population.</p><p>Sampling was based on data from the National Institute of Statistics (NIS). PThe population corresponds to the official 2008 estimates from the 2002 national census, distributed according to age, gender, and region of residency. Sample size calculation was performed estimating a prevalence of 80% who suffer dental caries; the sample size necessary to achieve a 95% (confidence interval: 95%) precision rate, with a 0.02 per cent range of error, was calculated to be 1553 adults (sample size with a statistical weight).</p><p>Adults selected to participate in this study were chosen using a multistaged probabilistic sample model that involved all 15 administrative regions in Chile. A sample with statistical weight was used to generate unbiased total variance estimations. Sample statistical weights were adjusted in order to obtain a certain number of individuals according to the referent base population of Chile, considering the differences by gender, age, region location, and city size class. In the first stage, the samples of all fifteen regions (primary sampling units) were obtained from data registered in the NIS. From the same source, we obtained the sample of each regions capital city (second stage). The third stage consisted of the municipalities in order to select the specific houses (fourth stage). All the adults in the sample were proper candidates for examination. In case of refusal to participate, replacements came from the next household belonging to the sex and age group that accepted to participate until completing the number of individuals defined for each specific commune.</p><p>More than 40% of the total Chilean population resides in the Metropolitan Region, this region includes the national capital city (Santiago) and 32 municipalities more.

The study protocol was previously explained to all patients, and informed consents were signed for each individual prior to entering the study. At the end of the clinical examinations, participants who were diagnosed with pathological conditions were provided with a written report of their condition and were advised to seek oral health care.</p></sec><sec id="sec2.2"><title>2.2.

Discussion</title><p>The sample used in this study is representative of the population between 35–44 and 65–74 years old in Chile. This is the first study including these years of age groups at the national level. According to WHO recommendations for collecting epidemiological data, the most important comparable years of age groups are represented by 35–44 and 65–74 years old individuals [<xref rid="B9" ref-type="bibr">9</xref>].</p><p>In Chile, as in most countries in the world, population is aging. The Chilean population has experienced a process of demographic transition, with an important decrease in fecundity rate and mortality rate in all ages. Life expectancy has raised from 58 years old in the 1960–65 period to 78.12 years old in 2012. Chile is challenged to improve and maintain oral health in adult and senior populations. </p><p>In Chile, oral health policies are hardly focused on populations up to 20 years old. Therefore, the oral health care services for adults are scarce [<xref rid="B13" ref-type="bibr">13</xref>].</p><p>According to WHO recommendations, oral health surveillance for monitoring adults oral health conditions must be done in the 35 to 44-year-olds. In this group, we can evaluate the effects of dental caries, periodontal diseases, and in general, the effects of oral health care services [<xref rid="B9" ref-type="bibr">9</xref>]. On the other hand, 65 to 74-year-olds is an important age group for seniors' oral health monitoring, since population's aging and the increase in life expectancy. The results of this study can be used for oral health care planning and for evaluation of final results of the dental services and care of the elder population [<xref rid="B9" ref-type="bibr">9</xref>]. From this point of view, the data collected is highly relevant for the design, implementation, and evaluation of oral health public policies tending to diminish the inequities in health. </p><p>In spite of the importance of epidemiological studies in adults and seniors, only a very reduced number of articles about the dental situation of these years of age groups in national sample from Latin America has been published. These studies show a very high prevalence of caries, affecting 65.3–100% of the mentioned population [<xref rid="B14" ref-type="bibr">14</xref>–<xref rid="B16" ref-type="bibr">16</xref>].</p><p> The DMFT index values observed in our study (15.06 in 35–44-year-old and 21.57 in 65–74-year-old groups) are higher than those found in more developed countries. For example, in New Zealand, the mean DMFT in 35–44-year-old was 10.0 (95% CI 9.2–10.8) and 24,2 (95% IC: 23,5–24,9) in 65–74-year-old adults [<xref rid="B18" ref-type="bibr">17</xref>]. In the second National Survey of Oral Health in China (2002), the mean DMFT in 35–44-year-old adults was 2.1 (DS: 2.8) and 12.4 (SD 17.4) in the 65–74-year-old group [<xref rid="B18" ref-type="bibr">17</xref>]. In Spain, the national surveys in the 35–44-year old group made in 1984, 1993, 2000, and 2005 showed a DMFT of 11.6, 10.9, 8.4, and 9.6, respectively, whereas for 65–74-year-old adults, the 3 national surveys in 1993, 2000 and 2005 showed a mean DMFT of 21.16, 18.10, and 16.8, which shows a decrease in the caries experience [<xref rid="B19" ref-type="bibr">18</xref>]. </p><p>Only two South American countries have carried out surveys with national samples with oral exam in adults: Colombia (1999) with a DMFT of 15.00 in the 35–44-year-old group and 19.6 in the “older than 55” group [<xref rid="B14" ref-type="bibr">14</xref>] and Brazil with a mean DMFT of 20.1 for 35–44-year-olds and 27.3 for the 65–74-year-old group in 2003 and a 16.3 and 27.0 DMFT for the 35–44 and the 65–74 adults, respectively, in 2010 [<xref rid="B16" ref-type="bibr">16</xref>]. In Chile, according to our study, we can see a mean DMFT of 15.06 and of 21.57 for the 35–44 and the 65–74 adults, respectively. </p><p>Our findings in terms of caries prevalence are lower than previous studies carried out during the 90s in Chile. Gamonal (1996) found almost 100% of caries experience in low and middle-low socioeconomic level adult populations [<xref rid="B20" ref-type="bibr">19</xref>]. We found statistically significant differences between males and female in both years of age groups. Unfortunately, separate figures from previous studies for both men and women are not available for comparisons. This reduction in the damage level of the population's oral health possibly is related to the implementation of a water fluoridation programme in Chile in the mid-1990s and the enhanced conditions in the quality of life in the Chilean population throughout the last years.</p><p>The level of edentulism is a good indicator of populations' oral health because the main cause may not only be a carious process, but also many other reasons. In several developed countries, we can see a decrease in the prevalence of edentulism in the new adult cohorts. In the USA, among the young adults group, in the NHANES III 1988–1994, the prevalence of edentulism was 10.8%, and in 1999–2002 it diminished to 7.7%. The level of edentulism of the present study can be seen as an unfavourable situation compared to other countries like Canada, United States, Lithuania, and China [<xref rid="B18" ref-type="bibr">17</xref>, <xref rid="B21" ref-type="bibr">20</xref>, <xref rid="B22" ref-type="bibr">21</xref>]. </p><p>Moreira et al. [<xref rid="B23" ref-type="bibr">22</xref>] in a systematic literature review from 1986 to 2004 concerning the most prevalent oral problems experienced by elderly Brazilians reported a high percentage of edentulism, with a prevalence between 5.2 and 84%, with the major reported numbers with a prevalence over 60%. Tooth loss has been shown to be associated with oral health impact profile, worse physical functioning, and low perception in quality of life [<xref rid="B24" ref-type="bibr">23</xref>, <xref rid="B25" ref-type="bibr">24</xref>]. </p><p>The condition of diabetes, depression, and obesity was declared by the patients during the questionnaire applications, and these conditions were not clinically evaluated. Among the reasons for the increase observed in tooth loss in individuals that declared depression, we found a relation to less personal care, alterations in immune response, and the frequent consumption of medication that affects salivary flow. Depression is also found more frequently in low socioeconomical status individuals [<xref rid="B26" ref-type="bibr">25</xref>].</p><p>In conclusion, adult population in Chile showed a high prevalence of dental caries and tooth loss, as age, education level, personal and familiar incomes and depression are being the main risk factors. This situation constitutes a great challenge for the health profession considering the increasing of life expectancy of the population.</p><p>These observations in caries prevalence in the adult population in Chile suggest that it may be necessary to develop and implement oral health policies taking into account geographical and socioeconomical differences in populations. Because of the lack of epidemiological studies in adults in the South American countries, the data collected in this study may be useful to build a more complete profile of oral health conditions, as well as being a complement to the analysis of the global trends of the disease.</p></sec></body><back><ref-list><ref id="B1"><label>1</label><element-citation publication-type="journal"><person-group
