Periodontitis and systemic parameters in chronic kidney disease: Systematic review and meta-analysis.

OBJECTIVE: To perform a systematic review with meta-analysis to assess recent scientific evidence on the association between periodontitis and systemic parameters/conditions in individuals with chronic kidney disease (CKD). MATERIALS AND METHODS: The search for studies was performed in MedLine/PubMed, Scopus, Web of Science, and BIREME databases. Reference lists of selected articles were also searched. Studies with different epidemiological designs evaluating the influence of exposure to periodontitis on serum markers and mortality in individuals with CKD were eligible for inclusion. Three independent reviewers performed the article selection and data extraction. The assessment of methodological quality used the adapted Newcastle Ottawa Scale. Random effects meta-analysis was performed to calculate association measurements and 95% confidence intervals. RESULTS: In total, 3053 records were identified in the database search, with only 25 studies meeting the eligibility criteria and, of these, 10 studies contributed data for meta-analysis. Using a random-effects model, periodontitis was associated with hypoalbuminemia (PRunadjusted = 2.47; 95%CI:1.43-4.26), with high levels of C-reactive protein (PRunadjusted = 1.35; 95%CI%:1.12-1.64), death from cardiovascular disease (RRunadjusted = 2.29; 95%CI:1.67-3.15) and death from all causes (RRunadjusted = 1.73; 95%CI:1.32-2.27). CONCLUSIONS: The findings of this review validated a positive association between periodontitis and serum markers and mortality data in individuals with CKD.

Association between periodontitis and severe asthma in adults: A case-control study.

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.

Comparison of caries lesion detection methods in epidemiological surveys: CAST, ICDAS and DMF.

BACKGROUND: Although dental caries is a globally widespread disease, there is no consensus regarding the method that should be used for their detection. In recent decades, a variety of new methods have been proposed for measuring caries in a population. Three caries detection methods, the decayed, missing and filled (DMF) index, the International Caries Detection and Assessment System (ICDAS) and the Caries Assessment Spectrum and Treatment (CAST), were compared to provide information to guide future method choices. METHODS: This was a descriptive, cross-sectional study in which three methods were used to measure caries in students, staff and their dependents at UNEB (State University of Bahia), Salvador, Brazil. We compared the mean application time of each method and the frequencies obtained by each method using the following indicators: the most severe caries lesion per individual; the mean number of missing, filled and decayed teeth; and the disease extent. RESULTS: The mean time taken to apply the DMF was 3.8 min; for ICDAS, it took 8.9 min, and for CAST, 4.7 min. When calculating the indicator the most severe caries lesion per individual, the prevalence rates were as follows: 28.1% for DMF, 84.0% for ICDAS and 75.0% for CAST. The mean numbers of decayed, missing and filled teeth were 6.0 according to the DMF, 6.2 according to ICDAS and 5.9 according to CAST. When the disease extension indicator was used, the following percentages of teeth were affected by caries: DMF 22.12%, ICDAS 49.11% and CAST 33.2%. CONCLUSIONS: The DMF underestimated the occurrence of caries lesions in individuals but was the fastest method to apply. ICDAS obtained detailed information regarding lesion severity, but it was a time-consuming method and difficult to analyse. CAST described disease distributions very well and identified lesion severities and preventive and curative needs in the examined group, and the time required to apply CAST was similar to that of the DMF.

The knowledge and use of population-based methods for caries detection.

BACKGROUND: Since the 1980s, a wide variety of methods have been proposed to measure dental caries in the population, demonstrating a lack of consensus regarding the procedure that should be used for this purpose. The current study investigated the methods that are known and used by public oral health researchers and professors as well as the reasons that lead to the choice of a particular method. METHOD: In the context of an interview, a questionnaire was administered to public oral health researchers and professors who used caries indices and worked in Salvador and Feira de Santana, Bahia, Brazil from 2005 to 2015. A quantitative and descriptive approach was applied that adopted the multiple correspondence analysis (MCA) technique to assess the associations among responses. RESULTS: The decayed, missing, and filled index (DMF) was the only measurement known by all respondents, and although 45 of the 47 professors/researchers were dissatisfied with this index, only six had used other methods. This index was chosen because of its comparability and ease of application. The MCA revealed response associations among older, male participants who graduated from the Federal University of Bahia (UFBA) and who continued to use this index because of its comparability and because it is the index recommended by the World Health Organization (WHO) and the Brazilian Ministry of Health (MS). Another group was also observed that consisted of younger females who graduated from the State University of Feira de Santana (UEFS) or another university and who used the DMF because it is well-known, simple, and easy to apply. CONCLUSIONS: The DMF index was the most known and used method. Many respondents demonstrated a desire for change and were critical of the DMF; however, they did not know of and had not used newer methods for measuring dental caries. Greater importance should be placed on the problem of dental caries assessment in the population.

Effect of maternal periodontitis and low birth weight--a case control study.

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.

Public Dental Service Access Policies for People with Autism Spectrum Disorder (ASD) in Salvador, Bahia, Brazil: A Pre-Evaluation Study.

This study sought to carry out a systematic and preliminary evaluation of the policies on access to public dental services for people with ASD in a Brazilian city. The study, conducted between November/2019 and February/2020, was developed through document analysis, the design of the theoretical logical model of the policies, and seven semi-structured interviews with key informants. The sample was intentionally selected. We also considered the answers to 108 questionnaires from a pilot study on the access of people with ASD to dental services applied to caregivers, dentists, and non-dental professionals. No refusals were recorded. The availability study showed that the policies' objectives were not being achieved in terms of care network organization: there were no institutional flows, personal contacts were used between professionals to guarantee access to secondary attention, there was no specific training for the dentists about ASD, and the oral health care network was unknown to non-dentist professionals and caregivers. Most people with ASD have visited the dentist at least once in their lives, but a large percentage of those within this study did not do so in the last year. This study identified difficulties in implementing policies and suggested possible strategies for overcoming them as dimensions and subdimensions for evaluation.

Oral health-care practices and dental assistance management strategies for people with autism spectrum disorder: An integrative literature review.

ABSTRACT: Autism spectrum disorder requires a careful approach from professionals and a favorable clinical environment for dental care and assistance. This article aims To perform a literature review about oral health among people with autism spectrum disorder and dental management strategies for this group. An integrative literature review was carried out in three databases, associating the descriptors: (autism or autism spectrum disorder) with (oral health or oral diseases) and (dental care or dental services). After identification and screening steps, 32 articles were included in the study. The most prevalent subjects were oral health conditions, parents' understanding and practical attitudes about oral health, treatment and management strategies, and the use of technology. The principal barriers to dental care were the scarcity of specialized professionals, unpreparedness in the referral system, poor accessibility of the clinics, and lack of specific care protocols. The world literature on the subject is scarce, and there is still a need for investment and scientific production due to the incidence of autism in the world population and the maintenance of difficulties and barriers in offering quality health care to this group.

The effect of antireaction medications on the association between periodontitis and leprosy reactions: An important methodological issue in periodontal medicine.

BACKGROUND: The treatment of leprosy reactions (LRs) involves thalidomide, corticosteroids, and other immunomodulatory medications. This study evaluated the effect of these treatments on the association between periodontitis and LRs, as well as factors associated with LRs. METHODS: This case-control study was conducted on 283 individuals followed at a leprosy outpatient clinic in Brazil. The case group was comprised of 158 individuals presenting type 1 or type 2 LRs, and the control group of 125 leprosy individuals without reactions. A complete oral examination was performed to diagnose periodontitis, the independent variable. Antireaction medication used was collected from medical records, and participants were classified according to the use of prednisone and/or thalidomide, time of use, or non-use of medication. Socioeconomic-demographic, clinical, and lifestyle covariables were collected by interview. Unconditional logistic regression analysis by subgroups evaluated the effect of antireaction medication on the association between periodontitis and LRs, estimating the odds ratio with a 95% confidence interval (OR; 95% CI). RESULTS: A relationship between periodontitis and LRs was observed only in the subgroup using the association prednisone and thalidomide: ORadjusted = 0.32; 95% CI = 0.11-0.95. Conversely, more severe periodontal clinical parameters were observed in cases versus controls. Several socioeconomic, health conditions, and lifestyle factors were associated with the presence of LRs. CONCLUSIONS: Although periodontal disease indicators were worse among the cases, the findings showed a negative relationship between periodontitis and LRs in individuals receiving associated prednisone and thalidomide. These medications appear to influence the inflammatory cascade between diseases, modifying and masking the manifestations of periodontitis.

Excessive weight in pregnant women increases the chance of diagnosing periodontitis combined with tooth loss.

BACKGROUND: Excess weight (EW), especially in women of childbearing age, those who are pregnant, as well as postpartum, is a problem worldwide. Fat accumulation deregulates the inflammatory response, contributing to the development of health problems, such as periodontitis. This study investigated the association between EW and periodontitis during pregnancy. METHODS: A cross-sectional, multicenter study involved 1745 postpartum women in Brazil. Socioeconomic-demographic data, gestational history, lifestyle behavior, and general and oral health conditions were obtained. Pre-pregnancy body mass index (BMI) was collected from medical records with EW being the exposure. Both tooth loss and clinical attachment level (CAL) were evaluated, and the presence of periodontitis was the outcome. Logistic regression, odds ratio (OR) and 95% confidence interval (95% CI), and quantile regression, beta coefficient and 95% CI, estimated the association between EW (BMI) and periodontitis and its combined effect with tooth loss ≥3, as dichotomous and continuous variables (CAL and tooth loss), with 5% significance level. RESULTS: The EW was 27.7% prevalent and periodontitis was 11.7%. There was a positive association between EW and periodontitis: ORadjusted:1.39; 95% CI:1.01;1.92 and between EW and periodontitis combined with tooth loss ≥3: ORadjusted:1.73; 95% CI:1.36;2.20. The adjusted association between EW and periodontitis as continuous variables was also positive, showing that for each unit of increased BMI, there was an elevation in the mean CAL (p = 0.04) and tooth loss (p < 0.01), with statistical significance. CONCLUSIONS: There was a moderate association between EW and periodontitis during pregnancy, with an even greater association of pregnant women with EW presenting periodontitis combined with tooth loss.

Mothers' high glycemic levels and the association between periodontitis and low birth weight.

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: A total of 732 women took part in this case-control study; 172 were mothers of children with LBW <2,500 g, and 560 were mothers of children with BW ≥2,500 g. 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 7 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 to 2.31; using the Gomes-Filho et al. criteria the ORadjusted was 1.91; 95% CI, 1.06 to 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.

Association between occupational exposure to domestic solid waste and dental caries: a cross-sectional study.

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.

Chronology and sequence of deciduous teeth eruption in children with microcephaly associated to the Zika virus.

INTRODUCTION: Deciduous teeth eruption is connected to children's growth and development. In Brazil, with the increase in the occurrence of children born with microcephaly associated to exposure to Zika virus, studies about orofacial alterations were necessary. OBJECTIVE: Describe the chronology and sequence of deciduous teeth in children with microcephaly due to the fetal exposure to Zika virus. METHODOLOGY: A cross-sectional study involving 74 children of a neuropediatric reference unit in Salvador, Bahia, in 2017 was conducted. Through use of secondary data, interviews with mothers and children's exam, the population was characterized, the chronology and sequence of deciduous teeth eruption was registered, and the analysis of the variables was proceeded. RESULTS: The first eruption happened between 4 and 17 months of age and 52.70% had a delay in the eruption of incisors. The average eruption time for the maxilla varies from 17.92 (16.56-19.28; 95% CI) to 20.43 (19.35-21.51; 95% CI) months, and the jaw from 11.57 (6.85-18.99; 95% CI) to 20.20 (19.09-21.31; 95% CI) months. In 77.94% of population, the eruption of the first teeth was in the lower arch and in 33.82%, molars and/or canines erupted before the incisors. CONCLUSIONS: There were alteration in the chronology and sequence of deciduous teeth eruption.

Health-Related quality of life of oral health workers in primary health care in Salvador, Brazil / Qualidade de vida relacionada à saúde de trabalhadores de saúde bucal da atenção primária à saúde em Salvador, Brasil / Calidad de vida relacionada con la salud de trabajadores de salud bucal de la atención primaria de salud en Salvador, Brasil

This study aimed to identify and determine the level of factors associated with the health-related quality of life (HRQoL) of oral health professionals working in Primary Health Care (PHC) in Brazil. A cross-sectional survey was carried out among 96 dentists and 65 dental assistants working in the Family Health Strategy (FHS) in six municipalities in the metropolitan area of Salvador (BA), Brazil. The HRQoL was evaluated using the 36-item Short Form Health Survey Questionnaire (SF-36). Higher mean scores in the SF-36 physical component summary were associated with younger age, post-graduate education in public health, and frequent leisure time. The mental component summary was associated with frequent leisure time, > 40 weekly working hours, suitable dental offices, satisfaction with colleagues, and satisfaction with working in PHC. The HRQoL level of oral health professionals working in primary health care in PHC in Brazil was comparable to those found in the available literature and associated with several modifiable factors. Incidentally, a literature search found few studies using the SF-36 to assess the HRQoL of oral health workers, and those found were produced outside the main scientific centers.

O objetivo deste estudo foi identificar e determinar o nível de fatores associados à qualidade de vida relacionada à saúde (QVRS) de profissionais de saúde bucal que atuam na Atenção Primária à Saúde (APS) no Brasil. Foi realizado um estudo de corte transversal com 96 cirurgiões-dentistas e 65 auxiliares em saúde bucal que atuam na Estratégia Saúde da Família (ESF) em seis municípios da região metropolitana de Salvador (BA), Brasil. A QVRS foi avaliada usando o 36-item Short Form Health Survey Questionnaire (SF-36). Escores médios mais altos no resumo do componente físico do SF-36 foram associadas a idade mais jovem, pós-graduação em saúde pública e tempo de lazer frequente. O resumo do componente mental foi associado a tempo de lazer frequente, > 40 horas semanais de trabalho, consultórios odontológicos adequados, satisfação com os colegas e satisfação em trabalhar na APS. O nível de QVRS dos profissionais de saúde bucal que atuam na APS no Brasil foi comparável aos encontrados na literatura disponível e associado a vários fatores modificáveis. Incidentalmente, uma pesquisa bibliográfica encontrou poucos estudos que utilizam o SF-36 para avaliar a QVRS de trabalhadores da saúde bucal; e os encontrados foram produzidos fora dos principais centros científicos.

Las puntuaciones medias más altas en el resumen del componente físico del SF-36 se asociaron con una edad más joven, títulos de posgrado en salud pública y tiempo libre frecuente. El resumen del componente mental se asoció con tiempo libre frecuente, > 40 horas de trabajo por semana, consultorios dentales adecuados, satisfacción con los colegas y satisfacción con el trabajo en la Atención Primaria de Salud. El nivel de CVRS de los profesionales de la salud bucal que actúan en la Atención Primaria de Salud en Brasil fue comparable a los encontrados en la literatura disponible y se asoció a varios factores modificables. Una búsqueda bibliográfica encontró pocos estudios que utilizan el SF-36 para evaluar la CVRS de los trabajadores de la salud bucal; y los encontrados estaban fuera de los principales centros científicos.

Oral health status of pregnant and puerperal women in the municipality of Feira de Santana, at three different times between 2005 and 2015. / Condição bucal de gestantes e puérperas no município de Feira de Santana, em três diferentes períodos entre os anos de 2005 e 2015.

OBJECTIVE: to evaluate the oral health condition of pregnant/postpartum women attending public services in the city of Feira de Santana, BA, Brazil, at three different times between 2005 and 2015. METHODS: this is a study socioeconomic and demographic characteristics, health condition and health care, lifestyle and oral health status of 1,245 participants obtained from a database of three previous investigations: I Intervention Study (2005-2007); II Case-Control Study (2010-2011); III Case-Control Study (2012-2015). RESULTS: comparing the three periods, the frequency of gingivitis (24.41% versus 8.90% versus 5.77%; p<0.01) and periodontitis (44.64% vs 9.16% vs 11.55%; p<0.01) was found to decrease; the worst dental conditions regarding the number of teeth present, healthy and extracted and the DMFT index were found in period III compared to period II. CONCLUSION: an improvement was seen in the participants' periodontal condition over time, which coincides with the implementation of policies pertaining to women's health, oral health and income redistribution in this city.

Risk factors for caries-free time: longitudinal study in early childhood.

OBJECTIVE: To estimate time in days from the beginning of follow-up up to the development of dental caries in children under 30 months and to assess risk factors potentially affecting the development of the disease. METHODS: The study population of the cohort study were children attending public, private, and charitable day care centers in Salvador, Northeastern Brazil, followed up for fourteen months. We used the multivariate Cox regression to estimate risk and Kaplan-Meier method to estimate the caries-free time. RESULTS: Of the 495 children studied, 112 developed caries (22.6%). Mean caries-free time was 248.6 (SD = 96.2) days. The comparasion of curves by age group (> 24 months) and children attending public day care showed more caries in a shorter period (p < 0.00). The following variables were important risk factors for increased rate of caries: district of origin (HR = 1.88, 95%CI 1.27-2.77), category of day care (HR = 3.88, 95%CI 2.04-7.38), age (HR = 1.77, 95%CI 1.15-2.74), bottle-feeding before sleep time after the age of 12 months (HR = 1.62, 95%CI 1.04-2.51), presence of active white spots (HR = 2.70, 95%CI 1.07-6.80), and living in non-masonry house (HR = 1.68, 95%CI 1.02-2.76). The highest hazard ratio (HR = 4.60, 95%CI 2.80-7.42) was found for previous caries experience. CONCLUSIONS: Social variables were considered as of high risk for the development of dental caries.

Maternal risk behavior and caries incidence in children with sickle cell disease.

The aim of this study was to analyze the incidence of caries, in relation to maternal risk behaviors and clinical conditions representing different levels of sickle cell disease severity. A total of 295 children aged 6 to 60 months participated in this cohort conducted from August 2007 to December 2008. They were diagnosed and monitored by the referral service of the state. Interviews were made with families to identify sociodemographic variables, and an oral exam was performed to determine dental caries. The SRQ (Self Report Questionnaire) scale was used to diagnose the presence of common mental disorders, and the CAGE (Cut down, Annoyed, Guilty and Eye opener) was applied to determine abusive use of alcohol. The absolute and relative frequencies of the variables of interest were analyzed by Chi-square and Mann-Whitney, with a 5% significance level. The incidence variables were analyzed according to the logistic regression model, with a confidence interval of 95%. Caries incidence (1.98; SD = 4.68) was higher in the HbSS genotype. There was a statistically significant association between caries incidence and both abusive use of alcohol (32.43%, RR = 1.99; 1.05-3.78; 95%CI) and common mental disorders (8.77% RR = 0.37; 0.15-0.93; 95%CI). There was also an association between caries incidence and maternal risk behavior, indicating that the care network should be expanded to include patients with sickle cell disease.

Diferentes critérios de definição da periodontite em puérperas jovens e sua associação com o baixo peso ao nascer / Different criteria for periodontitis definition in young mothers and its association with low birth weight

Objetivo: comparar três critérios de definição da periodontite na associação da doença periodontal com o baixo peso ao nascer (BPN) em uma população de puérperas jovens de Salvador, BA. Metodologia: aplicaram-se três diferentes critérios de definição da periodontite a uma amostra de 202 mães de bebês com peso ≥ 2.500g (controles) e de 97 mães de bebês com BPN (casos) pertencentes a uma base de dados de um estudo caso-controle prévio. Para a análise da associação entre periodontite e BPN, construíram-se modelos para os três critérios. A regressão logística não-condicional foi realizada para estimar a Odds Ratio (OR) baseada em Intervalos de Confiança a 95%. Resultados: a idade média das mães foi de 26,29 anos. A maioria declarou-se negra/ parda (92.64%), não fumante (94,65%) e possuir renda de até um salário-mínimo (61,20%). A ocorrência da periodontite variou de 22,41% a 94,31%, segundo o critério usado. Estimando-se a OR ajustada, a periodontite definida pelo critério 1 [ORajust. = 0,94, IC (95%)= 0,56­1,56], critério 2 [ORajust=1,18, IC(95%)= 0,65-2,13] e critério 3 [ORajust= 0,87, IC(95%)=0,37-3,22] não esteve associada com o BPN. Conclusão: flexibilizar o critério de definição interferiu na magnitude das medidas de ocorrência, mas não influenciou a análise de associação entre a periodontite e o BPN.

Objective: to compare three criteria for periodontitis definition and its association with Low Birth Weight (LBW) in a population of young mothers, in the city of Salvador ­ BA. Methods: Three different definitions for periodontitis were applied to sample of 202 mothers of newborns (NB) weighing ≥2.500g (controls) and 97 mothers of NB with LBW (cases) belonging to database from a previous case-control study. For the analysis of the association between periodontitis and LBW, were created models for three criteria. An unconditional logistic regression was used to estimate the odds ratio (OR) with 95% confidence interval. Results: the average age of mothers was 26,29 years. Most respondents identified themselves as black or brown (92.64%), 94,65% nonsmokers (94,65%) and have income up to 1 minimum wage (61.20%). The occurrence of periodontitis varied between 22,41% to 94,31% according to the criteria. When estimating adjusted OR, the periodontitis defined by criterion 1 [ORajus=0,94, IC(95%)=0,56­1,56], criterion 2 [ORajus=1,18, IC(95%)= 0,65-2,13] and criterion 3 [ORajus=0,87, IC(95%)=0,37-3,22] did not demonstrate association with LBW. Conclusion: to flex periodontitis' criteria modified the magnitude of measures of occurrence but did not influence the association analysis between periodontitis and the BPN.

Periodontal health and oral mucosal lesions as related to occupational exposure to acid mists.

OBJECTIVES: The association between exposure to acid mists and periodontal changes and oral mucosal lesions was measured using data from an Oral Health Promotion Program in a large metal plant. The role of sociodemographic factors, lifestyle, and oral health behavior in relation to these outcomes was also examined. METHODS: This is a cross-sectional study of 665 active male workers who volunteered to participate in the oral health program. A job exposure matrix was constructed with industrial hygienist scores and job titles to estimate years of exposure to acid mists. Oral health outcomes were identified during standardized dental examinations. Unconditional logistic regression models were utilized in the analysis. RESULTS: Duration of exposure to acid mists exposure was positively associated with oral mucosal lesions among workers without lip sealing. Only age, low salaries and oral hygiene-related variables were associated with periodontal changes, and estimates varied according to lip sealing. CONCLUSIONS: Results suggest that long-term occupational exposure to acid mists is associated with oral mucosal lesions, and that absence of lip sealing may increase the intensity of exposure.

Association between clinical manifestations of sickle cell anemia in children and the occurrence of dental caries: a cross-sectional study / Associação entre manifestações clínicas da anemia falciforme em crianças e a ocorrência de cárie dentária: um estudo de corte transversal

Objective: The aim of this study was to determine the association between clinical manifestations of sickle cell anemia (including hospitalization and pain crisis) and dental caries in children in Bahia. Material and Methods: The study design was crosssectional, and the population included children aged from 6 to 96 months from August 2007 to July 2008 (N = 686). Interviews were performed to identify the sociodemographic profiles of the participants, and oral examinations were conducted by three examiners who were previously trained and calibrated to identify the presence of dental caries according to World Health Organization (WHO) criteria. Logistic regression analysis was performed for confirmatory analysis and estimation of confidence intervals (CIs). Results: The results showed that pain crises and hospitalizations were positively associated with caries (crude odds ratio (OR) = 2.11 and adjusted OR = 1.24; crude OR = 2.50 and adjusted OR = 1.46, respectively), but these associations were not statistically significant. Conclusion: The severity of the sickle cell condition alone was not sufficient to aggravate the prevalence of caries; thus, there are no major differences in caries prevalence between children with and without sickle cell disease.

O objetivo deste estudo foi determinar a associação entre as manifestações clínicas da anemia falciforme (incluindo hospitalização e crise de dor) e cárie dentária em crianças na Bahia. Material e Métodos: O desenho do estudo foi transversal e a população incluiu crianças de 6 a 96 meses de agosto de 2007 a julho de 2008 (N = 686). Foram realizadas entrevistas para identificar os perfis sociodemográficos dos participantes, e os exames bucais foram realizados por três examinadores previamente treinados e calibrados para identificar a presença de cárie dentária de acordo com os critérios da Organização Mundial da Saúde (OMS). A análise de regressão logística foi realizada para análise confirmatória e estimativa de intervalos de confiança (IC). Resultados: Os resultados mostraram que as crises de dor e hospitalizações foram positivamente associadas à cárie (razão de chances bruta (OR) = 2,11 e OR ajustado = 1,24; OR bruto = 2,50 e OR ajustado = 1,46, respectivamente), mas essas associações não foram estatisticamente significantes. Conclusão: A gravidade da doença falciforme isoladamente não foi suficiente para agravar a prevalência de cárie; assim, não há grandes diferenças na prevalência de cárie entre crianças com e sem doença falciforme.(AU)

Métodos para detectar a doença cárie em populações: uma revisão da literatura / Methods to detect caries disease in populations: a review of the literature

Introdução: métodos para mensurar a cárie são essenciais na produção do conhecimento sobre a doença, na observação da sua distribuição nos diferentes lugares e populações, na investigação dos fatores de risco, bem como no adequado planejamento em saúde bucal. Objetivo: realizar uma revisão de literatura no intuito de atualizar o conhecimento científico produzido sobre este tema nos últimos dez anos de forma a contribuir para a escolha do melhor método para mensurar cárie em populações. Metodologia: pesquisou-se nas bases de dados SciELO e PubMed os descritores, cárie dentária, índice CPO, inquérito epidemiológico de cárie. O critério de seleção dos artigos foi a proposição de um novo método para mensurar cárie. Resultados: foram selecionados 12 estudos que utilizaram diferentes métodos, foram descritas as vantagens e ou desvantagens de cada um deles. Conclusão: a existência na literatura de tantos novos métodos demonstra que não existe um consenso a respeito de qual é o melhor para mensurar a cárie, dificultando a comparação dos resultados entre as populações

Introduction: methods for measuring caries are essential for the detection of caries in epidemiological surveys in population groups. These methods are important in the production of knowledge about the disease, in the investigation of risk factors, as well as in oral health planning. Objective: to carry out a literature review to update the knowledge on the subject with articles produced in the last 10 years. Methodology: the descriptors, DMF index, caries dental; caries health surveys were searched in the SciELO and PubMed databases The criterion of selection of the articles was the proposition of a new method to measure caries. Results: we selected 12 studies and described the advantages and disadvantages of each one. Conclusion: the existence in the literature of so many new methods demonstrates that there is no consensus on the best way to measure caries, making it difficult to compare results among populations
