Abstract Recent evidence points to the influence of periodontal inflammatory processes on the occurrence of low birth weight. Although many studies employed robust investigation methods, there is still no general agreement on the relationship between maternal periodontitis and low birth weight. The search for studies was conducted until April 2019. The studies included cohort and case-control studies that estimated the association between periodontitis and low birth weight, with no restriction on language or date of publication. Analysis of the heterogeneity of studies, subgroup analyses and meta-analyses with a random effects model were performed. Summary association measurements were estimated using the crude and adjusted Odds Ratio, with respective 95% confidence intervals. Visual inspection of graphs was used to assess publication bias. A total of 21 articles were identified, all of which were selected for the meta-analysis. The final model indicates that periodontitis in pregnant women was associated with low birth weight (ORgross=2.13; CI95%=1.60-2.83; I2=80.0% and ORadjusted=2.64; CI95%=2.04-3.42; I2=17.4%). Pregnant women with periodontitis may be more than twice as likely to have low birth weight babies.

Abstract In the last five decades, considerable progress has been made towards understanding the etiology and pathogenesis of periodontal diseases and their interactions with the host. The impact of an individual periodontal condition on systemic homeostasis became more evident because of this knowledge and prompted advances in studies that associate periodontitis with systemic diseases and conditions. The term Periodontal Medicine describes how periodontal infection/inflammation can affect extraoral health. This review presents the current scientific evidence on the most investigated associations between periodontitis and systemic diseases and conditions, such as cardiovascular diseases, diabetes, preterm birth and low birth weight, and pneumonia. Additionally, other associations between periodontitis and chronic inflammatory bowel disease, colorectal cancer, and Alzheimer’s disease that were recently published and are still poorly studied were described. Thus, the aim of this review was to answer the following question: What is the future of Periodontal Medicine? Epidemiological evidence and the evidence of biological plausibility between periodontitis and general health reinforce the rationale that the study of Periodontal Medicine should continue to advance, along with improvements in the epidemiological method, highlighting the statistical power of the studies, the method for data analysis, the case definition of periodontitis, and the type of periodontal therapy to be applied in intervention studies.

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.

RESUMO Objetivo Determinar a associação entre a presença de patógenos periodontais e o baixo peso ao nascer. Métodos Trata-se de estudo observacional e caso controle. Participaram mães de bebês com peso <2.500g (Grupo A) e de recém-nascidos com peso ≥2.500g (Grupo B) nascidos no Hospital da Mulher, em Feira de Santana, (BA). Dados demográficos, história gestacional e aspectos relacionados à saúde geral e bucal foram obtidos por meio de questionário semiestruturado, aplicado no período pós-parto. Após exame periodontal completo, as amostras de biofilme foram coletadas em seis locais na boca. As participantes foram também categorizadas quanto à presença ou ausência de periodontite. As diferenças entre os grupos foram obtidas pelo teste do χ 2 de Pearson, odds ratio e os intervalos de confiança pelo teste de Mantel-Haenszel. Resultados Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia e Prevotella intermedia foram detectados por reação em cadeia de polimerase. Avaliaram-se 303 mulheres pós-parto, sendo 224 (73,9%) do Grupo B. Diferenças estatisticamente significativas entre os grupos foram observadas quanto à idade, ao índice de massa corporal e a história de partos prévios com bebês de baixo peso ao nascer. O Grupo A apresentou maior frequência de periodontite (33,34%) do que o Grupo B (16,22%). P. gingivalis e P. intermedia foram detectados com maior frequência em mulheres com periodontite (74,19% e 88,70%, respectivamente). Conclusão Nessa população, não houve associação entre a presença de patógenos periodontais maternos e a ocorrência de bebês com baixo peso ao nascer.

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 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.

ResumoO objetivo deste estudo foi avaliar os níveis de satisfação dos usuários adultos do município de Lauro de Freitas, no Estado da Bahia, em relação aos serviços de saúde bucal oferecidos pela Estratégia de Saúde da Família (ESF). É um estudo descritivo, quantitativo, com a aplicação de dois instrumentos validados: o Questionário de Avaliação da Satisfação dos Usuários com os Serviços Públicos de Saúde Bucal (QASSaB) e parte do Questionário do Projeto SBBrasil 2010. A amostra foi de 418, com erro amostral de 5%. Foi feita a distribuição de frequência das variáveis quantitativas e de medidas de tendência central e de dispersão, por meio do programa estatístico SPSS. Os resultados mostraram que a maior parte dos entrevistados era do sexo feminino (78,2%), da raça/cor preta (47,0%) e solteira (46,1%). Em relação à morbidade bucal referida, a maioria reportou a necessidade de tratamento odontológico (91,4%). Dor de dente nos últimos seis meses foi relatada por 52,5%. Em relação às dimensões ambiente físico, aceitabilidade, eficiência, equidade, relações humanas e qualidade técnico-científica dos equipamentos, observou-se um bom grau de satisfação. Concluiu-se que, apesar de ainda persistirem muitos desafios para a melhoria da qualidade da atenção em saúde bucal na ESF, a satisfação dos usuários adultos foi alta.

The objective of this study was to evaluate the levels of satisfaction of the adult users of the municipality of Lauro de Freitas, state of Bahia, Brazil in relation to the oral-health services offered by the Family Health Strategy - ESF. This quantitative, descriptive study applied two validation instruments, the User-Satisfaction-Evaluation Questionnaire in conjunction with the Public Oral-Health Service and one part of the questionnaire from theSB Brasil2010Project. The sample size was 418 individuals, with a sampling-error rate of 5%. The quantitative variables and measurement of central tendencies and dispersion were distributed using the SPSS statistics program. The results demonstrated that most of those interviewed were women (78.2%), African descent (47.0%), and single (46.1%). In terms of the aforementioned oral morbidity, the majority reported the need for odontological treatment (91.4%). 52.5% reported toothache in the previous six months. A high degree of satisfaction was observed in relation to the dimensions of the physical environment, acceptability, efficiency, equality, human relations, and the technical-scientific quality of the equipment. In conclusion, despite the many challenges that persist to improving the quality of the oral-health services of the ESF, the level of satisfaction of adult users was high.

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.

OBJETIVO: Identificar os fatores associados à pneumonia nosocomial em hospital público de Feira de Santana, Bahia. MÉTODOS: Este estudo caso-controle foi realizado em 211 indivíduos adultos (46 casos e 165 controles), com idade média de 41 anos, atendidos na Clínica Médica, Clínica Cirúrgica ou na Unidade de Terapia Intensiva Adulta do Hospital Geral Clériston Andrade, em Feira de Santana. Os casos foram constituídos por indivíduos que desenvolveram infecção do trato respiratório (pneumonia nosocomial) após admissão hospitalar. Os controles foram formados por não portadores de pneumonia nosocomial. Informações socioeconómicas, história médica, estilo de vida e hábitos de higiene bucal foram obtidos por meio de entrevistas. Os prontuários foram checados para registro da condição de saúde do indivíduo e diagnóstico de pneumonia. Exame clínico bucal foi realizado por cirurgião-dentista treinado. Na análise bivariada, foi estimado o odds ratio (OR) como medida de associação e seus respectivos intervalos de confiança de 95% (IC 95%) com uso do método de Mantel-Haenzel. RESULTADOS: A frequência de pneumonia nosocomial na amostra foi de 21,8%. A ocorrência de hipertensão e o tempo de internamento foram maiores nos casos do que nos controles (p < 0,05). A falta de uso de fio dental e de enxaguatório bucal foram maiores no grupo controle (p = 0,01). CONCLUSÃO: Os achados apontam a hipertensão, tempo de internamento > 5 dias e ausência do fio dental e enxaguatório bucal como fatores possivelmente associados à pneumonia nosocomial, apontando-os como alvos efetivos de prevenção

OBJECTIVE: To identify factors associated with nosocomial pneumonia in individuals admitted to apublic hospital in Feira de Santana, Bahia. METHODS: This case control study was carried out in 211 adult individuals (46 cases and 165 controls), of a mean age of 41 years, treated at clinical wards, surgical wards or the adult intensive care unit of Cleriston Andrade General Hospital in Feira de Santana. The cases comprised individuals who developed respiratory tract infections (nosocomial pneumonia) after hospital admission. The controls consisted of patients without nosocomial pneumonia. Information on socioeconomic status, medical history, lifestyle and oral hygiene habits was obtained through interviews. The medical records were checked to verify subjects' health status and the diagnosis opneumonia. A clinical oral examination was performed by a trained dental surgeon. Odds ratio (OR) was estimated in the bivariate analysis as an association measurement, along with the respective 95% confidence interval through the Mantel-Haenszel method. RESULTS: The frequency of nosocomial pneumonia in the sample was 21.8%. The occurrence of hypertension was higher and hospital stay duration was longer in the cases than in controls (p ≤ 0.05). Lack of dental floss and mouthwash use were higher in the controls (p = 0.01). CONCLUSION: The findings indicate that arterial hypertension, length of hospital stay of five days and lack of dental floss and mouthwash use are factors likely associated with nosocomial pneumonia, suggesting that these factors should be targeted for effective prevention.

OBJETIVO: Proteína C-Reativa (PCR) é um marcador de inflamação presente no plasma cujos níveis podem se elevar devido a um processo inflamatório, ocasionando um maior risco a eventos cardiovasculares, como o Infarto Agudo do Miocárdio. A doença periodontal promove uma resposta imuno-inflamatória do hospedeiro, contribuindo com níveis mais elevados de PCR, esclarecendo sua associação com a doença cardiovascular. Objetivou-se neste estudo verificar o efeito da terapia periodontal nos níveis desse marcador inflamatório. METODOLOGIA: A amostra constou de 62 pacientes, de ambos os sexos, com faixa etária entre 30 e 60 anos, encaminhados para tratamento odontológico na Fundação Bahiana para Desenvolvimento das Ciências, e distribuídos entre dois grupos: com e sem periodontite. Os descritores clínicos empregados consistiram de Índice de Sangramento, Recessão Gengival, Profundidade de Sondagem e Nível de Inserção Clínica. Para a análise da PCR foi coletado sangue periférico dos indivíduos e encaminhados a um mesmo laboratório de análises clínicas. RESULTADOS: O grupo com periodontite foi tratado e os resultados mostraram que houve diferença estatisticamente significante entre os níveis de PCR antes e após o tratamento periodontal (P<0,05). CONCLUSÃO: De acordo com os achados finais, pode-se concluir que a terapia periodontal não cirúrgica apresentou uma tendência de redução dos níveis séricos da PCR.

PURPOSE: C-reactive protein (CRP) is a marker of inflammation that is naturally present in the plasma at levels that may rise due to inflammatory processes, associated with a greater risk of cardiovascular events such as acute myocardial infarction. Periodontal disease is responsible for a host immune-inflammatory response, contributing towards clarifying its association with cardiovascular disease. The aim of this study was to investigate the effect of periodontal therapy on the levels of this inflammatory marker. METHODS: The sample consisted of 62 patients of both genders, between the ages of 30 to 60 years, who were referred to dental treatment at the Bahia Foundation for the Development of Sciences, and they were divided into two groups: with and without periodontitis. The clinical descriptors used were the bleeding index, gingival recession, probing depth and clinical attachment level. For CRP analysis, peripheral blood was collected from these individuals and sent to a single clinical analysis laboratory. RESULTS: The group with periodontitis was treated and the results showed that there was a statistically significant difference between the CRP levels before and after periodontal treatment (P<0.05). CONCLUSION: From the final findings, it may be concluded that non-surgical periodontal therapy showed a tendency to reduce the CRP serum levels.

Para estimar a prevalência e os fatores associados à periodontite em uma área rural do Estado da Bahia foi realizado um estudo transversal com 172 indivíduos, de 20 a 60 anos de idade residentes no povoado de Matinha dos Pretos, Feira de Santana (BA). Durante visitas domiciliares, um exame clínico periodontal completo foi realizado para cada indivíduo, que também respondeu a um questionário a respeito de fatores sociodemográficos, econômicos e relacionados à saúde. Foram avaliados índice de placa, índice de sangramento à sondagem, profundidade de sondagem, medidas de recessão ou hiperplasia e calculada a perda de inserção clínica. Utilizou-se análise de regressão logística multivariada para avaliar a contribuição relativa desses fatores para a periodontite. A prevalência da doença periodontal foi de 24,42%. Ser homem (OR = 1,58; 1,00 - 2,53), ter 30 anos ou mais de idade (OR = 2,80; 1,00 - 7,39), residir em casas com mais de uma pessoa por cômodo (OR = 1,53; 0,96 - 2,45), fumar ou ser ex-fumante de cigarro ou cachimbo (OR = 1,49; 0,92 - 2,39), ter índice de placa maior do que 65% (OR = 2,97; 2,72 - 7,39) e mais de quatro dentes ausentes (OR = 1,51; 0,82 - 2,78) estiveram associados positivamente com a presença de doença. Concluiu-se que fatores socioeconômicos e biológicos, especialmente a higiene bucal inadequada e idade elevada, estão associados positivamente com a presença de periodontite na população rural de um povoado no Estado da Bahia, Brasil.

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.

OBJETIVO: Estudos recentes têm apresentado evidências de que a doença periodontal em gestantes pode ser um dos determinantes do baixo peso ao nascer. Realizou-se estudo para verificar a existência de associação entre doença periodontal materna e baixo peso ao nascer. MÉTODOS: Estudo do tipo caso-controle com 302 mulheres, sendo 102 mães de nascidos vivos de baixo peso (grupo caso) e 200 mães de nascidos vivos com peso normal (grupo controle). A existência de associação entre doença periodontal e baixo peso ao nascer foi avaliada mediante modelo multivariado de regressão logística, considerando outros fatores de risco para o baixo peso. RESULTADOS: Ambos os grupos de mães eram comparáveis no que se refere a idade, altura, peso pré-gestacional, tabagismo, alcoolismo, doenças prévias, estado civil, situação socioeconômica, número de escovações e uso de fio dental, número de refeições diárias, e visitas ao dentista. A doença periodontal foi diagnosticada em 57,8% das mães do grupo caso e 39,0% do grupo controle. A análise de regressão logística indicou associação positiva entre doença periodontal e baixo peso ao nascer (ORbruto=2,15; IC 95%: 1,32-3,48), especialmente entre as mães com escolaridade menor ou igual a quatro anos (ORajustada=3,98; IC 95%: 1,58-10,10). CONCLUSÕES: A doença periodontal é um possível fator de risco para o baixo peso ao nascer.

OBJECTIVE: Recent studies have presented evidence that periodontal disease in pregnant women may be a determining factor for low birth weight. The present investigation was carried out to verify whether or not there is an association between maternal periodontal disease and low birth weight. METHODS: This was a case-control study on 302 women, of whom 102 were the mothers of live newborns of low weight (case group) and 200 were the mothers of live newborns of normal birth weight (control group). The existence of an association between periodontal disease and low birth weight was evaluated by means of a multivariate logistic regression model that considered other risk factors for low weight. RESULTS: The two groups were comparable with regard to age, height, pre-gestational weight, smoking, alcohol use, previous diseases, marital status, socioeconomic status, frequency of tooth-brushing and use of dental floss, number of meals per day and visits to the dentist. Periodontal disease was diagnosed in 57.8% of the mothers in the case group and 39.0% in the control group. Logistic regression analysis indicated a positive association between periodontal disease and low birth weight (unadjusted OR=2.15; 95% CI: 1.32-3.48), especially among the mothers with schooling of less than or equal to four years (ORadjusted=3.98; 95% CI: 1.58-10.10). CONCLUSIONS: Periodontal disease is a possible risk factor for low birth weight.
