Comparative Study on the Periodontal Parameters Used in Diagnosing Periodontitis in Puerperae and Periodontitis' Relationship with the Birth of Preterm Infants: A Case-Control Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:156. [PMID: 38397649 PMCID: PMC10887772 DOI: 10.3390/ijerph21020156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 01/24/2024] [Accepted: 01/29/2024] [Indexed: 02/25/2024]
Abstract
To compare different criteria for the diagnosis of periodontitis and to evaluate the association of this condition with prematurity, this case-control study was conducted on 283 mothers of infants, divided into two groups based on gestational age (cases: <37 weeks, controls: ≥37 weeks), with 71 cases and 212 controls. The periodontal evaluation included probing depth (PD), clinical attachment level (CAL), plaque index, and bleeding on probing (BOP). Participants were classified regarding periodontitis per 14 criteria based on different periodontal parameters. The criterion selected as the gold standard was the presence of at least four teeth with one or more sites with a PD ≥ 4 mm, CAL ≥ 3 mm, and BOP at the same site. The prevalence of periodontal disease ranged from 8.1% to 55.1%. Moreover, compared to the gold standard, the sensitivities of the other criteria were 100%, while specificity ranged from 50.4% to 96.4%. Periodontitis, defined by six of the selected criteria, was associated with prematurity after multivariate adjustment, with OR ranging from 1.85 to 2.69 and 95% CI from 1.01 to 5.56; one of them was the gold standard mentioned above. Measurements using the clinical parameters of PD, CAL, and bleeding at the same site (criteria 5, 6, 7, 8), CPI (criterion 10), and at least four teeth with a PD ≥ 4 mm and CAL ≥ 3 mm (criterion 11) to define periodontitis showed a statistically significant association (p < 0.05). Given this study's limitations, we can conclude that the diagnostic criteria for a periodontitis definition using a PD ≥ 4 mm and CAL ≥ 3 mm in two or more teeth, with BOP at the same site, seem stronger when detecting an association between periodontitis and prematurity.

Association between hearing loss and cognitive decline in the elderly: A systematic review with meta-analysis study. PLoS One 2023; 18:e0288099. [PMID: 37943811 PMCID: PMC10635537 DOI: 10.1371/journal.pone.0288099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 06/19/2023] [Indexed: 11/12/2023] Open
Abstract
OBJECTIVE Hearing loss has been pointed out as a potential predictor for cognitive decline. This study conducted a systematic review to evaluate the scientific evidence on the association between hearing loss in the elderly and cognitive decline, as well as whether race/color influences this relationship. METHOD The search for studies was performed in the following electronic databases: MedLine/PubMed Web of Science, Scopus and Virtual Health Library, and MedRkiv up to August 2022. Studies with epidemiological designs that assess the association between hearing loss and cognitive decline in the elderly were eligible for inclusion. Three independent reviewers performed the selection, data extraction and evaluation of the quality of the studies using the Newcastle-Ottawa Scale. A meta-analysis using a random effects model estimated the global association measurements (Beta coefficient: β) and their 95% confidence intervals (95%CI), and the Higgins and Thompson indicator (I2) was also estimated to assess statistical heterogeneity among the studies. RESULTS 5,207 records were identified in the database surveys, of which only 18 were eligible studies, totaling 19,551 individuals. Hearing loss was associated with cognitive decline in the elderly, with statistical significance: β = -0.13; 95%CI = -0.23 to -0.04; I2 = 98.70%). For black individuals, the magnitude of the association increased: β = -0.64; 95%CI = -3.36 to 2.07; I2 = 95.65%, but it was not statistically significant. CONCLUSION The findings of this systematic review showed the existence of a significant relationship between hearing loss and cognitive decline in the elderly, as well as signaling that among black individuals the magnitude of the association can be increased.

Periodontitis severity relationship with metabolic syndrome: A systematic review with meta-analysis. Oral Dis 2023; 29:2512-2520. [PMID: 36346175 DOI: 10.1111/odi.14428] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 10/31/2022] [Accepted: 11/03/2022] [Indexed: 11/10/2022]
Abstract
The objective of this study was to investigate the association between periodontitis severity and metabolic syndrome (MetS) through systematic review, registered in PROSPERO: CRD42021232120. Selected articles were independently chosen by three reviewers from six databases, including using article reference lists, up until March 2022. Eligible studies were observational, without language limitation, and in subjects aged at least 18 years. The methodological quality of selected studies was assessed using the Newcastle-Ottawa Scale. Random effects models calculated summary measurements (odds ratio-OR, 95% confidence interval, 95%CI). The I2 test evaluated the statistical heterogeneity of the data. Sensitivity, subgroup, and meta-regression analyses were performed. For the reliability of evidence, the Grading of Recommendations, Assessment, Development, and Evaluations tool was used. A total of 2133 records were identified, and 14 studies were included comprising 24,567 participants. The summary odds ratio showed a positive association between individuals with moderate (ORadjusted = 1.26; 95%CI = 2.10-5.37; I2 = 45.85%), and severe periodontitis (ORadjusted = 1.50; 95%CI:1.28-1.71; I2 = 56.46%), and MetS. Subgroup and meta-regression analyses showed that study effect size was influenced by year of publication, study design, and MetS diagnostic criteria, contributing to inter-study variability. The findings showed that moderate and severe levels of periodontitis are associated with MetS, suggesting a possible dose-response effect.

Periodontitis in individuals with few remaining teeth and a high gingival bleeding index increases the probability of dyslipidemia. J Periodontol 2023; 94:1243-1253. [PMID: 37310101 DOI: 10.1002/jper.23-0091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 04/11/2023] [Accepted: 04/12/2023] [Indexed: 06/14/2023]
Abstract
BACKGROUND Dyslipidemia, a silent multifactorial condition, is characterized by changes in blood lipid levels, affecting all socioeconomic strata, increasing the risk for atherosclerotic diseases. This study investigated whether there is an association between dyslipidemia and the combined exposure of periodontitis plus the number of remaining teeth, gingival bleeding, or caries. METHODS A two-center cross-sectional study was conducted involving 1270 individuals, with a minimum age of 18 years. Socioeconomic and demographic data, health conditions, lifestyle parameters, and anthropometric, biochemical, and oral clinical examinations were performed. The exposures considered were the presence of periodontitis, dental caries, number of remaining teeth, and gingival bleeding. The outcome was dyslipidemia as defined by the Brazilian Guidelines on Dyslipidemia and Prevention of Atherosclerosis. The combined associations between periodontitis plus other oral health conditions and dyslipidemia were estimated using confounder-adjusted prevalence ratios (PRsingle , PRmultiple , for single and multiple covariable adjustments) with 95% confidence intervals (95% CIs), in a Poisson regression model with robust variance. RESULTS The occurrence of dyslipidemia was 70.1% and periodontitis was 84.1%. A positive association between periodontitis and dyslipidemia existed: PRsingle = 1.13; 95% CI: 1.01-1.26. Combined exposure of periodontitis plus <11 remaining teeth (PRmultiple = 1.23; 95% CI: 1.05-1.43), as well as combined exposure of periodontitis plus ≥10% gingival bleeding and <11 remaining teeth (PRmultiple = 1.22; 95% CI: 1.03-1.44), represented greater probabilities of 23% and 22% of individuals having a diagnosis of dyslipidemia. CONCLUSION Periodontitis combined with fewer than 11 teeth doubled the likelihood of being diagnosed with dyslipidemia.

Abstract
BACKGROUND Mental disorders represent a major public health challenge worldwide, affecting 80% of people living in low- and middle-income countries. Depression, a mental disorder, is a chronic disease of long duration that causes changes in the brain, resulting from a combination of genetic, physiologic, environmental, and behavioral factors. The aim of this study was to investigate possible factors associated with depression in Brazilian adults. METHODS A population-based, cross-sectional study was carried out using the public domain database of the 2019 National Health Survey, conducted in Brazil. Depression was considered the dependent variable, and through hierarchical analysis, predictor variables were investigated such as, at the distal level-socioeconomic variables, at the intermediate level-variables related to lifestyle behavior, health condition, and history, and at the proximal level-demographic variables. Logistic regression analysis was used to obtain the adjusted Odds Ratio and the respective 95% confidence interval to identify possible factors associated with depression. RESULTS The study included 88,531 participant records with 10.27% diagnosed with depression. The adjusted association measurements, after selecting the independent variables in the hierarchical analysis, showed the following factors associated with depression with differing magnitudes: age, brown and white race/skin color, female sex, poor, very poor, or regular self-reported health condition, diagnosis of cardiovascular disease, work-related musculoskeletal disorder, history of smoking habit, and macroeconomic region. CONCLUSIONS An effective strategy for preventing and managing depression in Brazilian adults must include the control of health status and lifestyle behavior factors, with actions and programs to reduce people's exposure to these factors, understanding that socioeconomic-demographic differences of each population can potentially reduce the disease burden.

Abstract
INTRODUCTION Neuropsychiatric diseases, particularly dementias, has become more prominent with a great impact on the quality of life of the elderly population. OBJECTIVE To verify the rate of increase in mortality due to Alzheimer's disease in the Federal District, Brazil from 2010 to 2018. METHOD An ecological study was conducted, with a time series, about the evolution of the mortality coefficient in the Federal District, Brazil carried out at the Federal District State Department of Health. Mortality rates were defined as the dependent variable and years evaluated as the independent variable-from 2010 to 2018. For temporal trend analysis, the Prais-Winsten linear regression model was used and the increment rate with the respective 95% confidence interval was estimated. RESULTS From 2010 to 2018, 1665 deaths which had Alzheimer's disease as the underlying cause were recorded in the Mortality Information System. The results showed an overall mortality rate of 6.55 deaths per 100,000 inhabitants, with a higher predominance in females, non-Black people, and those aged 80 years or older. There was an increase in the annual trend of the overall mortality coefficient in both sexes. CONCLUSION The findings demonstrated a significant increase in the temporal evolution of mortality due to Alzheimer's disease in the Federal District, Brazil. It was recommended to conduct original studies to evaluate the factors that can cause the disease in order to collaborate in the process of formulating policies in the area of public health and improvements in clinical practice.

Abstract
The aim of the study was to evaluate the association between salivary anti-Porphyromonas gingivalis IgA antibodies and the leprosy reaction. The levels of salivary anti - P. gingivalis IgA antibodies, together with salivary flow and pH were measured in individuals diagnosed with leprosy and associated with the development of the leprosy reaction. Saliva was collected from 202 individuals diagnosed with leprosy at a reference leprosy treatment center, 106 cases with the leprosy reaction and 96 controls without the leprosy reaction. Anti - P. gingivalis IgA was evaluated by indirect immunoenzyme assay. Non-conditional logistic regression analysis was employed to estimate the association between antibody levels and the leprosy reaction. There was a positive statistically significant association between the levels of anti - P. gingivalis IgA and the presence of the leprosy reaction, controlling for confounders: age, sex, level of education and alcoholic beverage consumption: ORajusted: 2.55; IC 95%: 1.34-4.87. Individuals with leprosy who had high levels of salivary anti - P. gingivalis IgA had approximately twice as many chances of developing the leprosy reaction. The findings suggest a possible relationship between salivary anti - P. gingivalis IgA antibodies and the leprosy reaction.

Abstract
OBJECTIVE Evaluate the association of genetic variants of the interferon gamma inducible protein 16 (IFI16) and absent in melanoma 2 (AIM2) genes with periodontitis. METHODS The study involved 117 individuals with periodontitis and 389 without periodontitis, all Brazilians, miscegenated. Individuals with periodontitis presented at least 4 teeth with ≥ 1 site with probing depth ≥ 4 mm; clinical attachment level ≥ 3 mm on the same site and bleeding upon stimulus. Genotyping was performed using the Infinium Multi-Ethnic AMR/AFR-8 Bead Chip focused on Hispanic and African American populations with approximately 2 million markers of the human genome. Multivariate logistic regression was performed to identify associations in additive, dominant and recessive models adjusted for covariates age, obesity, mouth breathing, flossing, asthma, and ancestry. RESULTS In IFI16, the rs75985579-A is positively associated with periodontitis in the additive (Odds Ratio adjusted (ORadjusted) 2.65, 95% confidence interval (CI):1.25-5.60, p value: 0.007) and dominant models (ORadjusted 2.56, 95%CI:1.13-5.81, p value: 0.017). In AIM2, the rs76457189-G, is associated negatively with periodontitis in two genetic models evaluated, additive (ORadjusted 0.21, 95%CI:0.05-0.94, p value: 0.022) and dominant (ORadjusted 0.21, 95%CI:0.05-0.94, p value: 0.022). CONCLUSIONS These results have shown that variants in the IFI16 and AIM2 genes are associated with periodontitis. Individuals with at least one A (adenine) allele of the rs75985579 (IFI16) are more than twice as likely to have periodontitis, while individuals with the G (guanine) allele of rs76457189 (AIM2) are less likely to be diagnosed with periodontitis, providing a negative association with periodontitis.

Abstract
Cocaine use is an increasingly frequent event, especially in young people, and can cause irreversible consequences, such as suicide. To evaluate the factors associated with cocaine use in the moments preceding to suicide. This is a population-based, cross-sectional, and analytical study conducted in the Brazilian Federal District by researchers from the Department of Health and the Civil Police Institute of Criminalistics. All people who died due to suicide in 2018 were included in the survey. Cocaine use was considered the dependent variable, and robust Poisson regression was performed to estimate the crude and adjusted prevalence ratios and their respective population confidence intervals. In 2018, 12,157 deaths were recorded, of which suicide accounted for 1.56% of all deaths. It was observed that being between 25 and 44 years old, male, and under the influence of alcohol or cannabis, had a strong positive association with cocaine consumption among suicide victims. Males, people with black skin, with lower level of education, with employment, and who were under the effect of the use of cannabis and/or alcohol in the previous hours of death had a higher propensity to consume cocaine immediately before suicide, with a moderate to strong magnitude of prevalence ratio. The findings of this research indicated the need for monitoring, by health services, of people most vulnerable to suicide through the consumption of psychoactive substances.

Abstract
OBJECTIVE To investigate the association between the severity of periodontitis (exposure) and dyslipidemia (outcome). METHODS This was a cross-sectional study of users of public health services. Periodontitis was defined using the Center for Disease Prevention and Control and the American Academy of Periodontology criteria. Lipid evaluation used data on systemic biomarkers. Dyslipidemia diagnosis was based on the Guidelines of total cardiovascular risk of the World Health Organization. Weight, height, waist circumference, and blood pressure were measured, and socioeconomic-demographic, lifestyle behavior factors, general and oral health conditions of the participants were collected. Hierarchical and logistic regression analyzes were used to determine the association between the exposures and the outcome. Odds Ratios, unadjusted and adjusted, and 95% confidence intervals were estimated. RESULTS Of 1,011 individuals examined, 75.17% had dyslipidemia, and 84.17% had periodontitis, 0.2% with mild, 48.56% moderate, and 35.41% severe disease. The association between periodontitis and dyslipidemia was maintained through hierarchical analysis and in the multiple regression modeling, showing that the occurrences of dyslipidemia in the group with periodontitis, and its moderate and severe levels, were, respectively, 14%, 30%, and 16% higher compared with those without periodontitis. CONCLUSIONS The results showed a positive association between moderate and severe periodontitis and dyslipidemia.

Abstract
OBJECTIVE To investigated the effect of oropharyngeal colostrum immunotherapy in reducing the time required for very low birth weight preterm newborns (VLBW-PTNB: < 1,500g and < 37 weeks) to achieve full enteral nutrition. METHODS Literature search was conducted using four databases, including gray literature, with additional manual search of the references of selected articles. Eligibility criteria consisted of randomized clinical trials, without restriction regarding the date or language of the publication. Two independent reviewers performed the article selection and data extraction. The random-effects meta-analysis used a non-standard technique to assess the mean difference in days to achieve full enteral nutrition, carried out by the Stata 15 statistic program. RESULTS The systematic review comprised 10 studies, and five were selected for meta-analysis, with a population of 764 VLBW-PTNB and gestational age of birth between 25 and 32 weeks. The studies were conducted between 2011 and 2018 in North America, Asia and Africa, with only one conducted in South America. Altogether, they reported the number of days it took 708 VLBW-PTNB to achieve full enteral nutrition, with newborns treated with immunotherapy showing a shorter time in only three studies. Meta-analysis showed a mean difference of -4.26 days, (95% CI -7.44; -1.08d), with high heterogeneity (I2 = 83.1%). CONCLUSION The use of oropharyngeal colostrum immunotherapy can reduce the time for VLBW-PTNB to achieve full nutrition when compared to those who used a placebo or received routine care.

Abstract
BACKGROUND Maternal hyperglycemia, periodontitis, and adverse gestational outcomes are important health problems. The present study investigated the hypothesis that periodontitis and the glycemic level of mothers may have opposing influences on birth weight (BW). This study evaluated the effect of high glycemic levels, albeit within the normal range, on the association between periodontitis and low birth weight (LBW). METHODS 732 women took part in this case-control study; 172 were mothers of children with LBW <2,500g, and 560 were mothers of children with BW ≥2,500g. The BW of newborns was obtained from medical records, and information on socioeconomic-demographic, lifestyle behavior were obtained through interviews. Glycated hemoglobin (HbA1c) levels were evaluated, and full-mouth periodontal examination was carried out within seven days postpartum. Hierarchical and logistic regression analysis evaluated the effect of glycemic levels on the association between periodontitis and LBW by subgroups, estimating Odds Ratios (OR) with 95% confidence intervals (95%CI). RESULTS In the group with HbA1c levels <5.6%, a statistically significant relationship existed between periodontitis and LBW. Using the Centre for Disease Control/American Academy of Periodontics criteria, the ORadjusted was 1.55; 95%CI: 1.04-2.31; using the Gomes-Filho et al. criteria the ORadjusted was 1.91; 95%CI: 1.06-3.45. In the group with higher HbA1c levels but still within the normal range (≥5.6% and <6.5%), the findings showed no association between periodontitis and LBW. CONCLUSION Higher maternal glycemic levels within the normal range, inferior to those indicative of gestational diabetes, diabetes mellitus, or hyperglycemia, and periodontitis have opposing effects on BW, altering the association magnitude.

Abstract
Leprosy reactions are immune processes that cause neural damage in individuals with leprosy. As periodontitis is an infectious disease related to its development, specific antibodies to periodontal pathogens must be evaluated to better understand the humoral mechanisms underlying this relationship. Therefore, the objective of this study was to standardize an immunoassay to measure IgA specific to P. gingivalis antigens in the saliva of individuals with leprosy. An ELISA checkerboard titration was performed. A validation test involving 53 individuals with leprosy, 24 with and 19 without periodontitis, was conducted and a ROC curve constructed to calculate sensitivity and specificity. The coefficient of the optical densities was 2.21 and 2.66 for P. gingivalis crude extract and the recombinant protein HmuY, respectively. Sensitivity and specificity for the P. gingivalis crude extract were 66.7% and 73.7%, respectively, and for HmuY, were 62.5% and 52.6%, respectively. Specific recognition of P. gingivalis occurred predominantly in individuals with periodontitis, which validates the use of this test for studying periodontitis in individuals with leprosy.

[PMID: 34164791 PMCID: PMC8221742 DOI: 10.1007/s11356-021-14890-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 06/09/2021] [Indexed: 06/13/2023]
Abstract
Studies have shown that domestic waste collectors are exposed to toxicants including infectious pathogens, which may be linked to their oral health conditions. This cross-sectional study evaluated the dental caries and its associated factors among domestic waste collectors. A total of 301 adult men who worked for a waste collection corporation were included; 171 men worked in direct contact with domestic solid waste and 130 did not. Sociodemographic data, working, and medical history were assessed. The decayed, missing, and filled permanent teeth (DMFT) index was examined. Logistic regression analysis was used to identify factors associated with dental status with a significance level of 5%. The overall mean DMFT score was 8.36±5.64. The mean DMFT, missing teeth (MT), and filled teeth (FT) were significantly higher in workers who did not have any direct contact with waste (p≤0.04). In the logistic analysis, DMFT ≥8 was only associated with older age (OR=8.41 [95% confidence interval (95%CI), 5.01-14.12], p<0.001). Decayed teeth (DT) ≥2 was associated with no previous oral hygiene instruction (OR=2.70 [1.50-4.81], p=0.001) and no daily dental flossing (OR=4.26 [1.92-9.43], p<0.001). MT ≥9 was associated with lower education level (OR=3.33 [1.57-7.10], p= 0.002). FT≥3 had a negative association with low income (OR= 0.42 [0.25-0.70], p<0.001) and no daily flossing (OR=0.42 [0.23-0.76], p=0.004). In conclusion, occupational exposure to domestic solid waste was not associated with poor dental status. Instead, age, education, income level, and oral hygiene were associated with dental health status. Missing teeth constituted the major component of the DMFT index. Therefore, prevention and oral rehabilitation programs are necessary to improve dental health.

Validation of a search strategy for randomized clinical trials related to periodontitis. ACTA ACUST UNITED AC 2021; 79:43. [PMID: 33812387 PMCID: PMC8019511 DOI: 10.1186/s13690-021-00560-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Accepted: 03/09/2021] [Indexed: 11/13/2022]
Abstract
Background Systematic reviews, considered the gold standard for the assessment of scientific evidence, may present conflicting findings for the same clinical issue, and such dissent may be justified by the forms of elaboration of the electronic search strategy. This paper aims to validate a search strategy to identify randomized clinical trials related to periodontitis. A gold standard reference set was developed to validate the identified clinical trials using the relative recall method. The choice of periodontitis is due to the fact that this disease has a high prevalence among chronic non-communicable diseases, is considered the second most common oral disease in the world, is associated with several health problems, such as cardiovascular diseases and diabetes, and, principally, has not been investigated sufficiently to prevent possible damages resulting from it. Methods A validation study was developed in MEDLINE/PubMed. In Stage 1, a methodological filter recommended by the Cochrane Collaboration to identify randomized clinical trials was applied. Stage 2 identified articles related only to periodontitis (gold standard reference set) from among the articles retrieved using the eligibility criteria. In Stage 3, a search statement for the retrieval of periodontitis-related articles was elaborated by experts. Stage 4 defined the proposed search strategy comprising of the combination of the search statement developed with the aforementioned methodological filter and subsequent application in MEDLINE/PubMed. The obtained data were analyzed using the set of articles identified in Stage 2, as the gold standard reference set. The following performance values were calculated - sensitivity, specificity, accuracy, and number needed to read - with their respective 95% confidence interval (95%CI). Results The search strategy under evaluation compared to the gold-standard showed a sensitivity of 93.2% (95%CI, 83.8–97.3), specificity of 99.9% (95%CI 99.8–99.9), and a precision of 77.5% (95%CI, 66.48–85.63). In addition, the number needed to read was 1.3. Conclusion According to the proposed methodological approach, the search strategy under evaluation performed well in the identification of randomized clinical trials related to periodontitis.

Associated factors to abusive alcoholic beverage consumption in suicide victims. Drug Alcohol Depend 2021; 221:108613. [PMID: 33662671 DOI: 10.1016/j.drugalcdep.2021.108613] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Revised: 01/25/2021] [Accepted: 01/26/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Suicide is a worldwide phenomenon, as well as a challenge for public health, and alcoholic beverage abuse is one of the most important risk factors. However, the association between possible factors related to alcoholic beverage consumption in suicide victims has rarely been investigated. OBJECTIVE To evaluate the factors associated with abusive alcoholic beverage consumption among people who died from suicide in the Brazilian Federal District (BFD). METHOD A population-based and cross-sectional study with suicide victims in the BFD between 2016 and 2017. Information was collected about sociodemographic characteristics, autopsy appraisal, and drug use. A trained team evaluated all cases to define factors associated with abusive alcoholic beverage consumption. This outcome was measured using the Blood Alcohol Concentration. Poisson regression analysis was applied to calculate the Prevalence Ratios and respective populational confidence intervals. RESULTS The findings of the present study were collected from a database containing information related to 278 suicide victims. Being male and having cocaine identified in the toxicological test were the factors that showed a strong association with abusive alcohol beverage consumption in suicide victims. Other factors showed a slight association (PR < 1.5): having an education level with greater than 8 years of study, being black, having a professional occupation or being retired or pensioner, and having the presence of cannabis in the toxicological test. CONCLUSION Socioeconomic-demographic and behavioral factors proved to be positively associated with abusive alcoholic beverage consumption among suicide victims, suggesting the need for effective public health policy measures to combat this health problem.

An accuracy study of the clinical diagnosis of periodontitis in pregnant women. J Periodontol 2020; 92:1243-1251. [PMID: 33252149 DOI: 10.1002/jper.20-0441] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Revised: 10/12/2020] [Accepted: 10/27/2020] [Indexed: 01/23/2023]
Abstract
BACKGROUND There exists a diverse range of criteria used in epidemiological studies for the diagnosis of periodontitis. The results from these studies should be evaluated with consideration to the diagnostic criteria used, and this may account for differences between studies especially in some population groups such as pregnant females. The objective is to evaluate the diagnostic criteria used in a variety of epidemiologic studies of periodontitis in pregnant females. METHODS An accuracy study with cross-sectional design was performed out from a database of 671 pregnant females, using six different sets of criteria for the diagnosis of periodontitis. Women were classified for periodontitis, as follows: Center for Disease Control and Prevention/American Academy of Periodontology (CDC/AAP, 2012 criterion), the gold standard, Gomes-Filho et al.(2018) criterion, Albandar et al.(2007) criterion, Bassani et al.(2007) criterion, López et al.(2002) criterion, and Nesse et al.(2008) criterion. For comparison amongst the gold standard and the other criteria, sensitivity, specificity, predictive values, and likelihood ratio were determined. RESULTS The frequency of periodontitis ranged from 25.0% to 90.2%. The Bassani et al. (2007) criterion was found to be more sensitive among the studies, and thus more suitable for diagnostic screening studies. Gomes-Filho et al.(2018), Albandar et al. (2007), López et al. (2002), and Nesse et al. (2008) criteria were considered more specific, which makes them more useful for studies of periodontitis with the aim of using diagnosis for confirmation of disease. CONCLUSIONS A variation in the occurrence of periodontitis was observed. The criterion must be chosen according to the research aims and population characteristics.

Abstract
OBJECTIVE This study investigated the association between periodontitis severity (exposure) and metabolic syndrome (MetS - outcome), using two criteria for diagnosis of the outcome, since this relationship remains unexplored. MATERIALS AND METHODS A case-control study was conducted with 870 individuals: 408 with first MetS diagnosis (cases) and 462 without MetS (controls). Participants' general information was obtained using a questionnaire and laboratory data was collected from medical records. Periodontitis severity criteria followed the Center for Disease Control and Prevention: none, mild, moderate, and severe. Odds ratios (OR) and 95% confidence intervals (95% CI) were determined by logistic regression analysis. RESULTS Findings showed a positive association between moderate and severe periodontitis and MetS: ORadjusted = 1.64 (95% CI: 1.01 to 2.68) and ORadjusted = 1.94 (95% CI: 1.19 to 3.16), respectively, after adjustment for age, sex, schooling level, smoking habit, and cardiovascular disease. The adjusted measurements showed that among individuals with moderate or severe periodontitis, the probability of having MetS was around two times greater than among those without periodontitis, and that the chance was greater among participants with severe periodontitis than those with moderate periodontitis. CONCLUSION An association between the severity of periodontal status and MetS was found, suggesting a possible relationship between the two diseases. CLINICAL RELEVANCE MetS influences the etiology of cardiovascular diseases, one of the leading causes of mortality worldwide. The findings suggest that the greater the severity of periodontitis, the greater is the association magnitude with MetS. The health professional needs to recognize that the importance of periodontal disease may play in MetS.

Abstract
Objective To determine the association between the presence of periodontal pathogens and low birthweight. Methods This observational and case-control study consisted of mothers of infants weighing <2,500g (Group A), and mothers of newborns weighing ≥2,500g (Group B), born at Hospital da Mulher in Feira de Santana (BA), Brazil. A semi-structured questionnaire covering demographic data, gestational history and aspects related to general and oral health was employed postpartum. Following a complete periodontal examination, biofilm samples were collected at six sites in the mouth. The participants were further categorized in terms of presence or absence of periodontitis. Differences between the groups were determined using Pearson’s χ 2 test, odds ratio, and confidence intervals were obtained using the Mantel-Haenszel test. Results Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia and Prevotella intermedia were detected by polymerase chain reaction. A total of 303 postpartum women were evaluated, 224 (73.9%) in Group B. Statistically significant differences between the groups were found for age, body mass index and history of previous low birthweight babies. Group A had a higher frequency of periodontitis (33.34%) than Group B (16.22%). P. gingivalis and P. intermedia were detected more frequently among women with periodontitis (74.19% and 88.70%, respectively). Conclusion In this population, there was no association between the presence of maternal periodontal pathogens and the occurrence of low birthweight infants.

Abstract
Objective: Dental caries and hyperglycaemia share common risk factors. The aim of this study was to identify factors associated with dental caries in women in the immediate postpartum period. It also verified whether women with hyperglycaemia presented more dental caries than those with normal glycaemia.Material and Methods: This cross-sectional study was performed on 297 women recruited from a teaching hospital in Brazil (from October 2011 to November 2012). Dental caries and oral biofilm were evaluated by oral examination. The blood glucose was accessed by Haemoglobin A1c test. Information on socioeconomic characteristics, harmful habits and oral health habits was also gathered.Results: More than half (66%) of the women had carious lesions. Univariate analysis showed no association between hyperglycaemia and dental caries (p = .39). The hierarchical logistic regression model showed that the following variables were associated with dental caries: maternal education level ≤8 years (ORadjusted = 2.40 [CI 1.19-4.82]), previous children (ORadjusted = 1.81 [CI 1.08-3.03), use of dental floss (ORadjusted = .48 [CI 0.27-0.86]), and visible plaque index ≥30% (ORadjusted = 1.83 [CI 1.05-3.20]).Conclusions: These findings call attention to the need to implement effective public policies directed at avoiding tooth decay in pregnancy and in the postpartum period.

Novel synthetic peptide derived from Porphyromonas gingivalis Lys-gingipain detects IgG-mediated host response in periodontitis. Anaerobe 2020; 61:102140. [PMID: 31838319 DOI: 10.1016/j.anaerobe.2019.102140] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 11/25/2019] [Accepted: 12/06/2019] [Indexed: 01/16/2023]
Abstract
Porphyromonas gingivalis is a keystone pathogen in periodontitis. Analysis of the immunogenicity of its virulence factors may provide insight into the host response to this infection. The Kgp12 (IEDB Epitope ID 763561), an epitope of Lys-gingipain (Kgp) virulence factor from P. gingivalis ATCC 33277, elicits an immunoglobulin G (IgG) immunoreactivity with low cross-reactivity and, therefore, more specificity. The aim of the present study was to determine in silico the localization of Kgp12 within the protein and to evaluate the IgG host response to this novel Kgp peptide through its capacity to differentiate individuals with different periodontal status. Sera of 71 volunteers were tested by indirect ELISA to detect the IgG immunoreactivity specific to Kgp12, as well as to the protein HmuY and to the sonicated total extract of P. gingivalis ATCC33277, both used as gold standard. The participants had no systemic disease and were classified according to periodontal clinical parameters to comparison, firstly, into periodontitis (P) and without periodontitis (WP) groups and, secondly, into periodontitis (P), gingivitis (G) and clinically health (CH) ones. All the antigens tested, Kgp12 (p = 0.02), HmuY (p = 0.00) and P. gingivalis extract (p = 0.03), could differentiate P from WP groups considering IgG serum levels. P group also had higher IgG levels specific to Kgp12 (p = 0.03), HmuY (p < 0.01) and P. gingivalis extract (p = 0.01) when compared to G group. We conclude that the Kgp12 synthetic peptide was useful to detect the IgG-mediated host response signaling that it is a promising epitope to analyze the immunogenicity of P. gingivalis.

Abstract
OBJECTIVE To conduct a systematic review and meta-analysis to evaluate the recent scientific literature addressing the association between periodontitis and asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. MATERIALS AND METHODS The search for studies was carried out using MEDLINE/PubMed, EMBASE, Lilacs, Web of Science, Scopus, and SciELO databases, including the gray literature (ProQuest). Reference lists of selected articles were also searched. Studies having varying epidemiological designs assessing the association between periodontitis and respiratory diseases in human subjects were eligible for inclusion. Three independent reviewers performed the selection of articles and data extraction. Fixed and random effects meta-analysis were performed for the calculation of the association measurements (Odds Ratio-OR) and 95% confidence intervals (95% CI). RESULTS A total of 3,234 records were identified in the database search, with only 13 studies meeting the eligibility criteria and 10 studies contributed data for meta-analysis. Using a random effects models periodontitis was associated with asthma: ORadjusted: 3.54 (95% CI: 2.47-5.07), I2 = 0%; with COPD: OR adjusted: 1.78 (95% CI: 1.04-3.05), I2 = 37.9%; and with pneumonia: OR adjusted: 3.21 (95% CI: 1.997-5.17), I2 = 0%. CONCLUSIONS The main findings of this systematic review validated an association between periodontitis and asthma, COPD and pneumonia.

Abstract
Serum hepcidin levels may increase in response to infection and inflammation. The present study investigated the effect of nonsurgical periodontal therapy (NSPT) on levels of serum hepcidin, inflammatory markers, and iron markers. An interventional study was conducted on 67 patients (age 30-65 years) without other diseases, except for chronic periodontitis (CP). Patients were allocated to either CP or control groups. The CP group received supragingival and subgingival scaling and root planing procedures, whereas the control group received supragingival scaling. Probing depth (PD), bleeding on probing, clinical attachment level (CAL), visible plaque index (VPI), serum hepcidin and interleukin-6 (IL-6) levels, high-sensitivity C-reactive protein (hs-CRP), hematological markers, and iron markers were measured at baseline and at 90 days after NSPT. The CP group had statistically significant lower mean values for mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) (p ≤ 0.05). The control group had statistically significant reductions in hemoglobin, hematocrit, MCV, and MCH (p ≤ 0.05). Serum hepcidin, IL-6, and erythrocyte sedimentation rate (ESR) levels were significantly decreased in both groups after NSPT. Periodontal markers were more markedly reduced in the CP group compared with the control group (p ≤ 0.05). These findings suggest that NSPT may reduce the serum levels of IL-6, hepcidin, and periodontal parameters.

Abstract
OBJECTIVE To investigate the association between maternal anemia and low/insufficient birth weight. DESIGN A prospective cohort study of pregnant women who underwent prenatal care at the healthcare units in a municipality of northeast Brazil together with their newborn infants was carried out. The pregnant women were classified as having anemia when the hemoglobin level was below 11 g/dl. Infants who were born full term weighing less than 2500 grams were classified as low birth weight, and those weighing between 2500 and 2999 grams were classified as insufficient weight. The occurrence of maternal anemia and its association with birth weight was verified using crude and adjusted Relative Risk (RR) estimates with their corresponding 95% confidence intervals (95%CIs). RESULTS The final sample was comprised of 622 women. Maternal anemia was considered a risk factor for low/insufficient birth weight, after adjusting the effect measurement for maternal age, family income, urinary infection, parity, alcoholic beverage consumption during pregnancy and gestational body mass index: RRadjusted = 1.38 [95% CI: 1.07 to 1.77]. CONCLUSIONS Maternal anemia was associated with low/insufficient birth weight, representing a risk factor for the gestational outcomes studied.

Abstract
This study aimed to investigate the factors associated with oral diseases in individuals with HIV/AIDS. A cross sectional study was carried out which included 312 individuals registered in the Specialized Care Services for HIV/AIDS in three municipalities of the State of Bahia: Feira de Santana, Santo Antonio de Jesus and Juazeiro, Brazil. Socioeconomic-demographic characteristics related to life style and to dental caries, periodontitis and intra-oral mucosal lesions were investigated in patients with HIV/AIDS infection. Prevalence Ratio with 95% Confidence Interval and significance level of 5% were employed for the statistical analysis. The majority of the individuals evaluated were male with a mean age (± standard deviation) of 41.5 ± 11.3 years, and a mean time of HIV infection diagnosis (± standard deviation) of 5.2 ± 4.4 years. The presence of dental caries was observed in 78.7% of the sample, periodontitis in 25.4% and 36.2% showed intra-oral lesions. Oral health status showed a statistically significant association with the following variables: gender, age, schooling level, current occupation, family income, past and current smoking, antiretroviral use time, latest viral burden dosage, latest CD4-positive T lymphocyte count, use of complete/partial dental prosthesis, need for dental prosthesis, and use of dental floss. With the exception of those factors directly related to HIV/AIDS i.e., antiretroviral use time, latest viral burden dosage and latest CD4-positive T lymphocyte count, the factors associated with oral diseases in this population were the same as those associated with oral diseases in the non-HIV/AIDS population.

Abstract
OBJECTIVE To evaluate the association between periodontitis and severe asthma, with participants in treatment for severe asthma, controlled by therapy. METHODS A case-control investigation was performed to compare 130 adults with severe asthma with 130 without asthma. Individuals with periodontitis were those with ≥4 teeth with ≥1 site with probing depth ≥4 mm, clinical attachment level ≥3 mm, and bleeding upon probing at the same site. Severe asthma diagnosis was based on Global Initiative for Asthma criteria. RESULTS Association between exposure to periodontitis and severe asthma was found: ORcrude = 2.98 (95% CI: 1.74-5.11). When confounders were considered, the association between exposure to periodontitis and severe asthma was maintained: ORadjusted = 3.01-3.25. Individuals with periodontitis had about a threefold increased risk of severe asthma than those without periodontitis. Frequency of periodontitis in participants with severe asthma was greater than that of those without asthma (46.6% vs 22.3%, p ≤ .05). CONCLUSIONS Association between periodontitis and severe asthma was observed. Further investigation is required to determine the direction of this relationship. It may be causal, but it may also be a consequence of the immunopathological process that characterizes asthma, or else, consequence of the medication used for treatment.

Abstract
BACKGROUND Metabolic syndrome (MetS) is a major factor for the occurrence of cardiovascular events. Causal factors for MetS are not well defined or yet unidentified. Preliminary investigations suggest that infections and inflammation may be involved in the etiology of this syndrome. This study aims to estimate the association between the severity of periodontitis (exposure) and MetS (outcome). METHODS A cross-sectional study was conducted with 419 participants recruited from the Diabetes and Hypertensive Treatment Center, Feira de Santana, Bahia, Brazil. After administration of a questionnaire, general and oral clinical examination and laboratory tests were performed. Diagnosis of periodontitis and MetS was performed according to various criteria. The analysis of the effect of periodontitis on MetS used logistic regression analysis with adjustment for confounders. RESULTS The prevalence of periodontitis was found to be between 34.61% and 55.37%, depending on the classification definitions used, and the prevalence of MetS ranged from 60.86% to 67.06%. In the group with periodontitis, 14.08% had severe and 41.29% had moderate levels of periodontitis. There was an association between severe periodontitis and MetS after adjustment for sex, age, household density, alcoholic beverage consumption, smoking habit, and cardiovascular disease (odds ratio ORadjusted_6 = 2.11, 95% confidence interval = 1.01 to 4.40, P = 0.05). CONCLUSIONS The results suggest that periodontitis is associated with MetS, and that MetS prevalence is related to severe periodontitis.

Abstract
INTRODUCTION Since the 1990s, evidence has been raised that there is an association between maternal periodontal disease and undesirable gestational events, for example low birth weight; this issue is controversial. OBJECTIVE To evaluate whether there is an association between maternal periodontitis and low birth weight (LBW). METHODS A case-control study was carried out on 951 mothers that had been cared for by the Brazilian Unified Health System in Petrolina-PE and Juazeiro-BA, Brazil. The case group (n = 269) consisted of mothers of newborns with birth weight <2500 g and a control group (n = 682) of mothers of newborns with birth weight ≥2500 g. An interview was realized, using a questionnaire as well as a full mouth examination to diagnose the periodontal condition. Women who had at least four teeth with probing depth ≥4 mm and clinical attachment loss ≥3 mm, with bleeding on probing at the same site, were diagnosed with periodontitis. The birth weight was obtained through the hospital book record. The main association was evaluated using the multivariate regression model, considering confounders. RESULTS The frequency of periodontitis was 16.4% (case group) and 17.4% (control group). Periodontitis did not show an association with LBW (ORcrude = 0.92; 95% CI = 0.63-1.35), even after adjustment for the following confounders: maternal age, pre-gestational body mass index, number of pre-natal consultations, number of pregnancies, maternal schooling level, smoking habit during pregnancy and hypertension (ORadjusted = 1.00; 95% CI = 0.61-1.68). CONCLUSION The findings of this study showed no association between maternal periodontal disease and low birth weight, even after appropriate adjustments for confounding factors.

Abstract
OBJECTIVE This study aimed to evaluate the occurrence of chromosomal abnormalities, through micronuclei, and apoptosis by the sum of karyorrhexis, pyknosis and condensed chromatin in individuals with chronic periodontitis, gingivitis associated with biofilm and no periodontal disease. MATERIALS AND METHODS This study included 72 individuals divided into three groups: gingivitis (n = 21), periodontitis (n = 24) and control (n = 27). Information on sociodemographic characteristics, health and lifestyle was obtained. Full mouth clinical examination was performed to define the periodontal condition. Exfoliated cells from gingival mucosa were collected for computation of micronuclei and nuclear changes indicative of apoptosis. The differences in the occurrence of endpoints (micronucleus, karyorrhexis, pyknosis and condensed chromatin) were evaluated using the conditional test to compare proportions in a rare events situation. RESULTS There was no statistically significant difference in the occurrence of micronucleus (p > 0.1) between gingivitis, periodontitis and control groups. The occurrence of apoptosis was significantly higher among individuals with periodontitis compared to individuals with gingivitis (p < 0.05) and controls (p < 0.025). CONCLUSIONS The findings showed that the inflammatory process generated by gingivitis and periodontitis is not related to a higher occurrence of chromosomal damage. However, the higher occurrence of apoptosis in individuals with periodontitis points to genotoxic effects induced by periodontal infection.

Abstract
BACKGROUND The effect of periodontal infection on systemic diseases and conditions has been the subject of numerous studies worldwide. It is considered that periodontitis may influence the hyperinflammatory response in patients with severe asthma as a result of immuno-inflammatory changes. This study aims to evaluate the influence of periodontitis on severe asthma in adults. METHODS A case-control study was carried out, comprising 220 adult individuals: 113 diagnosed with asthma (case group) and 107 without asthma diagnosis (control group). The diagnosis of periodontitis was established after a full clinical examination using probing depth, clinical attachment level, and bleeding on probing. The diagnosis of severe asthma was based on the criteria recommended by the Global Initiative of Asthma (2012). Descriptive analyses of the variables were performed, followed by bivariate analyses, using the χ(2) test. Association measurements (odds ratio [OR]), with and without adjustment for potential confounders, were obtained. A significance level of 5% was used. RESULTS The ORunadjusted for the main association was 4.38 (95% confidence interval [CI] = 2.47 to 7.75). In the logistic regression model, after adjusting for age, education level, osteoporosis, smoking habit, and body mass index, the ORadjusted was 4.82 (95% CI = 2.66 to 8.76), which was statistically significant. Individuals with periodontal infection showed, approximately, five times more likelihood to have bronchial inflammation than those without such periodontal tissue infection. CONCLUSION The findings demonstrate the influence of periodontitis on severe asthma, given that the frequency of periodontitis is higher in individuals with severe asthma than in those without a diagnosis of bronchial inflammation.

Abstract
UNLABELLED This study investigated whether osteoporosis/osteopenia has an influence on the progression of periodontitis in postmenopausal women. The findings highlight that postmenopausal women with osteoporosis/osteopenia had a greater chance of presenting periodontitis than those with normal bone mineral density, particularly among nonusers of osteoporosis medications and women with a greater number of remaining teeth, showing that osteoporosis/osteopenia has had an influence on the progression of periodontitis. INTRODUCTION This study investigated whether osteoporosis/osteopenia has an influence on the progression of periodontitis in postmenopausal women and explored the effects of use of osteoporosis medication and tooth loss on this association. METHODS This case-control study involved 521 postmenopausal women, with minimum age of 50 years, in Feira de Santana, Bahia, Brazil. Sociodemographic characteristics, health conditions/medications, and lifestyle habits were recorded. A complete periodontal examination was performed and periodontitis was diagnosed. Bone mineral density was evaluated through lumbar spine and femoral bone densitometry, obtained using dual-energy X-ray absorptiometry. Logistic regression was used to calculate the strength of association between the occurrences of osteoporosis/osteopenia and periodontitis. RESULTS Women with osteoporosis/osteopenia were twice as likely to present periodontitis, as were those with normal bone mineral density, even after adjusting for smoking, age, family income, and last visit to dentist (odds ratios (OR)adjusted=2.24, 95% CI [1.24-4.06], p=0.008). Among nonusers of osteoporosis medication (ORadjusted=2.51, 95% CI [1.33-4.73], p=0.004) and women with at least 10 remaining teeth (ORadjusted=2.50 95% CI [1.18-5.27], p=0.02), the odds ratio was higher and statistically significant. CONCLUSIONS These findings highlight that postmenopausal women with osteoporosis/osteopenia had a greater chance of presenting periodontitis than those with normal bone mineral density, particularly among nonusers of osteoporosis medications and women with a greater number of remaining teeth.

Abstract
UNLABELLED The influence of oral infections, especially periodontal disease, on systemic diseases has been extensively discussed in the literature. Because periodontal disease is a persistent infection, it promotes an inflammatory response. C-reactive protein is a marker for inflammatory reactions that is frequently studied, since elevated levels of this protein are related to coronary events. OBJECTIVE The aim of this study was to investigate the effect of periodontal therapy on reducing the serum levels of C-reactive protein, by means of a systematic review of the literature and meta-analysis. MATERIAL AND METHODS A systematic review of the English-language literature was conducted in the PUBMED-MEDLINE database, using the key words "periodontal disease", "C-reactive protein", "periodontal therapy" and "periodontal treatment", in accordance with the terms for Medical Subject Headings (MeSH), to evaluate the effect of periodontal therapy on C-reactive protein levels. A qualitative analysis of studies of randomized clinical trial design was performed using CONSORT, with subsequent meta-analysis. RESULTS The literature search initially retrieved 46 potentially relevant studies available in the databases. From these, in accordance with the inclusion criteria, only 11 were selected, of which only 4 fulfilled the criteria of randomized clinical trial design. According to CONSORT, the studies evaluated generally presented good quality with regard to the criteria analyzed. Through meta-analysis, the reduction in mean levels of C-reactive protein (-0.231; p=0.000) after introducing periodontal treatment was estimated. The result was statistically significant, without evidence of heterogeneity between the studies (p=0.311). CONCLUSIONS The findings indicated that non-surgical periodontal treatment had a positive effect with regard to reduction of the serum levels of C-reactive protein.

Abstract
BACKGROUND This study aims to analyze the relationship between chronic periodontitis and C-reactive protein (CRP) by considering associated variables in individuals with or without cardiovascular disease. METHODS A sample of 359 individuals of both sexes (aged ≥40 years) was assessed. Among these individuals, 144 subjects were admitted to the hospital because of a first occurrence of acute myocardial infarction; 80 subjects were in the hospital for reasons other than acute myocardial infarction; and 135 subjects were living in the community. A questionnaire was applied to obtain demographic and lifestyle characteristics. Complete clinical periodontal examinations and anthropometric assessments were performed. CRP levels, plasma glucose levels, lipid profiles, and blood tests were performed to investigate any conditions that might have suggested infection and/or inflammation. CRP evaluations were performed using nephelometry. Individuals were considered to have periodontal disease if they simultaneously presented at least four teeth with one or more sites with probing depth ≥4 mm, clinical attachment loss ≥3 mm, and bleeding on probing. Procedures for descriptive analyses and logistic regression were used. RESULTS In the chronic periodontitis group, mean CRP levels were higher than those in the group without chronic periodontitis (2.6 ± 2.6 mg/L versus 1.78 ± 2.7 mg/L, respectively). The final model showed that individuals with chronic periodontitis were more likely to have high CRP levels (adjusted odds ratio: 2.26; 95% confidence interval: 1.30 to 3.93) considering the effects of age, schooling level, sex, smoking, high-density lipoprotein cholesterol, and diabetes. CONCLUSION In this study, chronic periodontitis is associated with elevated plasma CRP levels, even after controlling for several potential confounders.

Abstract
OBJECTIVES The aim of this study was to evaluate the genotoxic effects of X-rays on epithelial gingival cells during panoramic dental radiography using a differentiated protocol for the micronucleus test. METHODS 40 healthy individuals who underwent this procedure for diagnostic purposes on request from their dentists agreed to participate in this study. All of them answered a questionnaire before the examination. Epithelial gingival cells were obtained from the keratinized mucosa of the upper dental arcade by gentle scraping with a cervical brush immediately before exposure and 10 days later. Cytological preparations were stained according to the Feulgen-Rossenbeck reaction, counterstained with fast green 1% for 1 min and analysed under a light microscope. Micronuclei, nuclear projections (broken eggs) and degenerative nuclear alterations (pyknosis, karyolysis, karyorrhexis and condensed chromatin) were scored. RESULTS The frequency of micronuclei was significantly higher after exposure (P < 0.05), as were the frequencies of nuclear alterations indicative of apoptosis (P < 0.001). CONCLUSIONS These results indicate that X-ray radiation emitted during panoramic dental radiography induces a genotoxic effect on epithelial gingival cells that increases the frequency of chromosomal damage and nuclear alterations indicative of apoptosis.

Abstract
OBJECTIVES Radiographic evaluation of periodontal conditions is a difficult process because of the many limitations inherent to this complementary examination and the lack of image specificity for different types of bone defects. The objectives of this study are to utilize digitized imaging resources to describe the radiographic features of different types of periodontal bone defects produced artificially in dry mandibles. METHODS 14 dry mandibles were utilized, in which periodontal bone defects were produced. Digital photographs and conventional radiographs of each site were obtained in a standardized manner, before and after producing these defects. The radiographs were then digitized, displayed on the screen and evaluated by three examiners. RESULTS Most of the bone defects presented distinct imaging characteristics that allowed them to be identified, with the exception of one-, two- and three-wall infrabony defects. The defects that were most easily interpreted were horizontal and vertical defects and the most difficult were defects in the radicular septum. CONCLUSIONS Despite the importance of imaging diagnoses in reaching clinical decisions regarding treatment, such diagnoses for different types of periodontal bone defects are extremely difficult to make. In the present study, the utilization of digital tools for interpreting digitized radiographic images facilitated the process.

Abstract
To estimate the prevalence and related aspects of periodontitis in a rural area of the State of Bahia, Brazil, this cross-sectional study was carried out in the village of Matinha dos Pretos, Feira de Santana County, Bahia, among 172 subjects ranging from 20 to 60 years of age. During household visits, a full-mouth periodontal exam was performed on each subject, who also answered a questionnaire about socio-demographic, economic and health-related issues. The factors assessed were plaque index, bleeding on probing index, probing depth, gingival recession or hyperplasia measurements. Clinical attachment loss was also calculated. The multivariate logistic regression method was used to evaluate the relative contribution of these factors to the periodontitis condition. The prevalence of periodontitis was 24.4%. The following factors were all positively associated with the presence of periodontitis: being male (OR = 1.58; 1.00 - 2.53), being 30 years of age or older (OR = 2.80; 1.00 - 7.39), living in a house where there was more than one person per room (OR = 1.53; 0.96 - 2.45), being a cigarette or pipe smoker or ex-smoker (OR = 1.49; 0.92 - 2.39), having a plaque index of over 65% (OR = 2.97; 2.72 - 7.39) and more than four missing teeth (OR = 1.51; 0.82 - 2.78). The authors concluded that socioeconomic and biological factors, especially poor oral hygiene and older age, are positively associated with periodontitis in the rural population of a small village in the county of Feira de Santana, State of Bahia, Brazil.

Abstract
BACKGROUND Limited information is available regarding the attached keratinized tissue, probing depth, and sociodemographic characteristics of primary teeth. This study was carried out to evaluate the relationship among age, gender, race, gingival width, and probing depth in each primary tooth type. METHODS The study population consisted of 300 children, aged 4 to 6 years, with clinically healthy gingiva, who were enrolled in an oral health program. Gingival width and probing depth were measured with a standard Williams periodontal probe in the middle of the keratinized gingiva and at six gingival sites (mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual, and disto-lingual), respectively. Schiller's solution was used to establish the limits of keratinized gingiva. RESULTS The gingival width (mean +/- SD) on the buccal surfaces decreased from anterior to posterior positions in both arches; in the lower lingual surfaces, the inverse was observed. The gingival width (mean +/- SD) ranged from 2.95 +/- 0.15 mm to 6.16 +/- 0.20 mm and the probing depth from 1.03 +/- 0.91 mm to 2.08 +/- 0.07 mm. There was a tendency toward increased probing depth as age increased from 4 to 6 years. There was also an increase in the probing depth from anterior to posterior teeth. CONCLUSIONS In the majority of observations, it was concluded that there was a relationship among age, gingival width, and probing depth, but generally not among race and gender and these measurements, respectively. Furthermore, there is no relation between gender and gingival width and race and probing depth.

Abstract
The genotoxic effects of X-ray emitted during dental panoramic radiography were evaluated in exfoliated cells from oral epithelium through a differentiated protocol of the micronucleus test. Thirty-one healthy individuals agreed to participate in this study and were submitted to this procedure for diagnosis purpose after being requested by the dentist. All of them answered a questionnaire before the examination. Cells were obtained from both sides of the cheek by gentle scrapping with a cervical brush, immediately before the exposure and after 10 days. Cytological preparations were stained according to Feulgen-Rossenbeck reaction and analyzed under light and laser scanning confocal microscopies. Micronuclei, nuclear projections (buds and broken eggs) and degenerative nuclear alterations (condensed chromatin, karyolysis and karyorrhexis) were scored. The frequencies of micronuclei, karyolysis and pycnosis were similar before and after exposure (P > 0.90), whereas the condensation of the chromatin and the karyorrhexis increased significantly after exposure (P < 0.0001). In contrast, both bud and broken egg frequencies were significantly higher before the examination (P < 0.005), suggesting that these structures are associated to the normal epithelium differentiation. The results suggest that the X-ray exposure during panoramic dental radiography induces a cytotoxic effect by increasing apoptosis. We also believe that the score of other nuclear alterations in addition to the micronucleus improves the sensitivity of genotoxic effects detection.
