Periodontitis has been associated with adverse pregnancy outcomes. Results from intervention studies are few and controversial. The present study assessed the effects of non-surgical periodontal treatment in the occurrence of adverse pregnancy outcomes. Two hundred forty-six eligible women were randomly divided into two groups: periodontitis intervention (n = 122; undergoing non-surgical treatment during gestation) and periodontitis control (n = 124; not treated during gestation). Univariate analysis was performed and estimates of relative risk were reported. Data from 225 women were analyzed. No differences for preterm birth (p = 0.721), low birth weight (p = 0.198), and preterm low birth weight (p = 0.732) rates were observed. Relative risk estimates for preterm birth, low birth weight, and preterm low birth weight in the periodontitis intervention group were 0.915 (95% CI 0.561-1.493), 0.735 (95% CI 0.459-1.179), and 0.927 (0.601-1.431), respectively. Non-surgical periodontal treatment during the second semester of gestation did not reduce the risk for preterm birth, low birth weight, and preterm low birth weight.
Autopercepção da saúde bucal e impacto na qualidade de vida do idoso: uma abordagem quanti-qualitativa Self-perception of oral health and impact on quality of life among the elderly: a quantitative-qualitative approachResumo Este estudo, de abordagem quanti-qualitativa, objetivou aprofundar o entendimento das relações entre autopercepção, impacto na qualidade de vida e condições bucais de idosos. Exame clínico e entrevista gravada contendo questões objetivas e discursivas foram realizados com 45 idosos. Conduziu-se análise descritiva quantitativa das questões objetivas e referentes ao exame clíni-co e à análise de conteúdo das questões discursivas de abordagem qualitativa. Imagens fotográficas do estado bucal foram relacionadas a trechos das entrevistas. A análise quantitativa evidenciou: 4,8 dentes em média; CPOD (número de dentes cariados, perdidos e obturados) médio de 29,9; 57,7% eram desdentados, 60% acreditavam não necessitar tratamento, 75% sofriam impacto na qualidade de vida devido às condições bucais, apesar de 67% perceberem positivamente sua saúde bucal. Na análise qualitativa constatou-se subestimação de sintomas, falta de esperança e resignação frente às limitações impostas pelo precário estado clínico. Muitos encararam as limitações como conseqüência do envelhecimento e não como problema que mereça ser corrigido. O que mais incomodou foram as relações de dependência e a proximidade com a morte, minimizando outros problemas. A população idosa foi informada de que poderia modificar sua autopercepção, conscientizando-a que esta realidade pode ser modificada. Palavras-chave Autopercepção, Saúde bucal, Qualidade de vida, Idosos, Pesquisa qualitativa Abstract A qualitative-quantitative approach was used in this study to obtain a clearer understanding of the relationship between self-perception, impact on quality of life and oral health among the elderly. Clinical examination and recorded interviews with objective and discursive questions were conducted with 45 institutionalized elderly people. Descriptive analyses of quantitative data were made. The interviews were transcribed and a systematic reading of the interviews was carried out selecting the components related to the categories under analysis. Photographic images of the oral clinical status were correlated with participants' speech. Quantitative analysis revealed: an average of 4.8 teeth; DMFT were 29.9; 57.7 % were toothless; 60% believed they did not need dental care; 75% suffered a great impact on quality of life due to oral health conditions, despite the fact that 67% evaluated their oral health positively. Underestimation of symptoms, lack of hope and resignation due to limitations regarding poor clinical status were detected. Most elderly people viewed such limitations as a consequence of aging and not as a problem that may be solved. This reality can be changed through information and guidance for elderly people.
BackgroundDental caries is the most prevalent oral disease in several Asian and Latin American countries. It is an infectious disease and different types of bacteria are involved in the process. Synthetic antimicrobials are used against this disease; however, many of these substances cause unwarranted undesirable effects like vomiting, diarrhea and tooth staining. Propolis, a resinous substance collected by honeybees, has been used to control the oral microbiota. So, the objective of this study was to develop and characterize sustained-release propolis-based chitosan varnish useful on dental cariogenic biofilm prevention, besides the in vitro antimicrobial activity.MethodsThree formulations of propolis - based chitosan varnish (PCV) containing different concentrations (5%, 10% and 15%) were produced by dissolution of propolis with chitosan on hydro-alcoholic vehicle. Bovine teeth were used for testing adhesion of coatings and to observe the controlled release of propolis associated with varnish. It was characterized by infrared spectroscopy, scanning electron microscopy, casting time, diffusion test in vitro antimicrobial activity and controlled release. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were tested for the main microorganisms involved in the cariogenic biofilm through the microdilution test in 96-well plates.ResultsThe formulations presented a tooth surface adherence and were able to form films very fast on bovine tooth surface. Also, propolis-based chitosan varnishes have shown antimicrobial activity similar to or better than chlorhexidine varnish against all oral pathogen bacteria. All microorganisms were sensitive to propolis varnish and chitosan. MIC and MBC for microorganisms of cariogenic biofilme showed better results than chlorhexidine. Propolis active components were released for more than one week.ConclusionAll developed formulations turn them, 5%, 10% and 15% propolis content varnish, into products suitable for clinical application on dental caries prevention field, deserving clinical studies to confirm its in vivo activity.
This study aimed was to test the association between quality of life and edentulism among elderly individuals in a city in southeastern Brazil. This cross-sectional study was carried out with 163 individuals aged 60 years or older, functionally independent and non-institutionalized. Data were collected with a questionnaire and oral examination. The edentulism was the dependent variable. The independent variables were sex, age, household income and quality of life (WHOQOL-Old) and their scores. To assess the association between the dependent variable and independent variables was used bivariate analysis (p < 0.10). Poisson regression model was performed, adjusting for age and sex. The average age of participants was 69 years (± 6.1), 68.7% were female and 52.8% were diagnosed as completely edentulous (90% CI: 0.33–1.24). When the independent variables were associated to the prevalence of edentulism, statistically significant associations were found for age (p = 0.03) and social participation dimension of the WHOQOL-Old (p = 0.08). In the Poisson regression, social participation remained statistically associated to edentulism {RP = 2.12 [90% CI (1.10–4.00)]}. The social participation proved to have a significant association to edentulism, thereby attesting to the negative effect of this condition on social aspects.
This study determined the prevalence of oral mucosal alterations and associated factors among the institutionalized elderly in Brazil. Data were collected through a structured questionnaire, a review of their medical records and an intra-oral examination. A sample of 335 individuals over 60 years of age was randomly selected. In total, 646 alterations were diagnosed; 59.1% were variations of the normal oral mucosa. The most frequent variation consisted of sublingual varicosities (51.6%). Denture stomatitis (15.2%) and denture hyperplasia (12.8%) were the most frequent lesions. Elderly patients who wore dentures had a significantly higher prevalence of oral mucosal lesions (p = 0.00) than those that didn't wear dentures. There was a high prevalence of variations of the normal oral mucosa and of mucosal lesions, especially denture-induced lesions, among the institutionalized elderly.
