Avaliação comparativa in vivo da eficácia do óleo de melaleuca, clorexidina e listerine sobre streptococcus mutans e microrganismos totais na saliva

Objective: To compare the efficacy of the mouthwashes 0.12% chlorhexidine, Listerine, and 0.5% and 2% Melaleuca Alternifolia oil against the salivary levels of Streptococcus mutans and total microorganisms. Methods: This study was double-blind controlled and paired clinical assay. Twenty-six volunteers aged 21 to 35 years old were enrolled. At baseline, 1 mL of unstimulated saliva was collected from each subject, 1 and 15 min after mouthrinsing with the following solutions: sterile distilled water, 0.12% chlorhexidine digluconate, Listerine (©Johnson & Johnson do Brasil), 0.5% and 2% concentrations of Melaleuca Alternifolia (Sigma-Aldrich). The volunteers used all the evaluated mouthrinses with a 15-day interval between the solutions. Immediately after rinsing, saliva was collected and serial dilutions were performed, followed by plating in blood agar culture medium for growth of total microorganisms and SB-20 (Sucrose-Bacitracin agar) for growth of S. mutans, and incubation at 37 °C for 48 h in microaerophilia. After incubation, the number of colonies was counted and expressed as colony forming units (UFC/mL). Results: Chlorhexidine showed antimicrobial action by reducing total microorganisms and S. mutans, while the action of 0.5% Melaleuca Alternifolia was similar to that of distilled water. Listerine and 2% Melaleuca Alternifolia oil reduced total microbial counts by 11% and 9% respectively, and S. mutans by 20% and 11%. Conclusion: A single rinse with 0.12% chlorhexidine is effective in reducing the levels of total microorganisms and S. mutans present in saliva. Under the same testing conditions, Listerine and 0.5% and 2% Melaleuca Alternifolia oil presented lower efficacy than chlorhexidine.

Detecção de Periodontopatógenos, Glicoproteína Emmprin (Cd-147) e sua correlação com MMP-2 e MMP-9

Periodontitis is an infectious disease characterized by the secretion of a variety of inflammatory mediators that lead to destruction of tooth supporting tissues, including the possible loss of alveolar bone, in association with infection with multiple species of bacteria. It is estimated that more than 400 species colonize the biofilm and some oral species related to periodontal disease is present in the subgingival including P. gingivalis, T. forsythia and T. denticola. However, other organisms may be related of this disease, as Filifactor allocis and Prevotella tannerae. These microorganisms and subproducts such as endotoxins released into the extracellular lead to the stimulation of metalloproteinase inducer glycoprotein (EMMPRIN, CD-147), which stimulates the release of MMPs by host cells, like fibroblasts and endothelial cells, thus leading to tissue destruction. The objective of this study was to detect F. allocis, P. tannerae, T. denticola and the glycoprotein EMMPRIN (CD-147) and its correlation with MMP-2 and MMP-9 in subgingival fluid samples of patients with chronic periodontitis. Fluids were collected from healthy and disease subgingival sites of 20 healthy individuals before basic periodontal treatment and after of 60 days of treatment. Their DNAs were extracted and portions of the 16S gene were amplified and performed conventional PCR. For immunological analysis and quantification of EMMPRIN (CD-147), MMP-2 and MMP-9 was used ELISA-Sandwich. Results demonstrated that the disease group showed significantly high amounts of T. denticola, F. alocis and P. tannerae when compared with health sites. MMP-2 and MMP-9 were detected in high concentrations with statistically significantly reduction after periodontal treatment to MMP-2, but without correlation with EMMPRIN.

Conhecimento odontológico de adultos atendidos em uma unidade de saúde da família do município de São Carlos, Brasil

The Family Health Strategy is a primary care public policy that is becoming a decisive step towards the transformation of the Brazilian healthcare model. This study evaluated the dental knowledge among individuals who attended a Family-Health Unit (FHU) in the city of São Carlos, SP, Brazil. Methods: The evaluation was based on a questionnaire with 20 questions about oral health, prevention and development of dental caries and periodontal disease. The questionnaire was given to 168 individuals, over 18 years of age and both sexes, to fill out under the supervision of a trained dentist. After data collection, the answers contained in the original questionnaires were entered into a database built using the program Excel® (Microsoft Corporation, USA) and a descriptive statistical analysis was done. Results: 66.67% of the subjects reported having received information about dental caries and periodontal disease before attending the FHU, and dentists were cited as the main source of such information (60.71%). With regard to dental caries, 70.24% of the individuals stated that they knew about the subject, but the majority of answers revealed incorrect explanation of it. The multifactorial etiology (bacteria/sugar/poor hygiene) was not mentioned. A low percentage of subjects (24.40%) claimed to know what periodontal disease is, and of these, the highest percentage of responses was related to gingivitis (26.83%) and gingival bleeding (12.20%). Out of all subjects, 80.36% affirmed that oral hygiene is important, and among them, the main reasons cited were the maintenance of oral health (29.63%), to avoid diseases (16.30%) and to preserve and prevent disease (14.81%). Conclusion: Responses from the questionnaires revealed deficient dental knowledge among the individuals. To improve the understanding about this issue, the information obtained through the questionnaire can be used to develop educational programs that will focus specifically on the major deficiencies found.

Impacto dos problemas de saúde bucal na qualidade de vida de gestantes

Objectives: 1) to evaluate the impact of oral health problems on the quality of life of pregnant women by the simplified Oral Health Impact Profile (OHIP-14) questionnaire as well by the presence of dental caries, periodontal disease and denture use/need; 2) to correlate the sociodemographic variables and the oral health conditions revealed in the clinical examinations with the OHIP-14. Method: In addition to the application of the OHIP-14 questionnaire, clinical examination of the oral conditions (CPI - community periodontal index, DMFT and prosthetic evaluation) was performed on 51 pregnant women, who sought dental treatment between April 2008 and August 2010 at the Preventive Dentistry Clinic. Descriptive analyses were made for sample characterization, bivariate analysis (chi-square or Fisher’s exact tests) and multiple logistic regressions at a 5% significance level to assess the correlation between the impact of oral health on the quality of life of pregnant women and the socio-demographic and clinical variables. Results: The OHIP-14 data showed a lesser impact of oral health on the women’s quality of life. The mean DMFT was 12.8; 70.6% of the pregnant women presented dental calculus and 58.8% needed prostheses. The association between OHIP-14 data and last dental visit and DMFT remained in the final regression model (p<0.05). Conclusion: Caries experience of the pregnant women was considered high. Most of them needed prostheses and presented dental calculus. The OHIP-14 presented a low impact on this population and was significantly influenced by the last dental visit and the DMFT index.

O Papel do cirurgião-dentista nas desordens alimentares: uma revisão de literatura

As desordens alimentares são um grupo de desordens psicopatológicas, nas quais o paciente relaciona os alimentos ingeridos com seu próprio corpo e, podem ameaçar a vida, como a anorexia e bulimia nervosa. Durante a progressão das desordens alimentares, pode ocorrer uma série de manifestações orais, as quais exercem um papel fundamental no diagnóstico, caracterização e prognóstico dessas desordens. O cirurgião dentista é, na maioria das vezes, o primeiro profissional da saúde a observar os sintomas clínicos de uma desordem alimentar. O objetivo deste trabalho foi realizar uma revisão de literatura sobre a etiologia, características, manifestações orais, e tratamento das lesões orais decorrentes das desordens alimentares. A pesquisa foi realizada nas bases de dados PubMed, SciELO, Bireme, durante o período de 1987 a 2013. Verifica-se assim que os primeiros sinais desenvolvidos em pacientes com desordens alimentares aparecem na cavidade oral, cabendo ao cirurgião dentista identificar esses sinais e relacioná-los às desordens.

Endodontics pastes formulated with copaiba oil: action on oral microbiota and dentin bridge formation in dogs

This study analysed the effect of pastes formulated with calcium hydroxide P.A. and different vehicles (saline solution - paste A and Copaifera langsdorffii Desfon oil - paste B) on oral microorganisms and dentin bridge formation in dogs. The antimicrobial action of the pastes and their components was analysed by the minimum inhibitory concentration in agar gel technique. The components were diluted and tested on fifteen standard strains of microorganisms associated with endodontic diseases. The microorganisms were cultivated and after incubation data was analysed using One-Way ANOVA and Turkey's test (P≤0.05). Four superior incisors of ten animals were used to evaluate dentin bridge formation. Two incisors were capped with paste A (GA) and two with paste B (GB). After 90 days, the teeth were extracted for histological analysis and the degree of dentin bridge formation evaluated. Data was analysed by the Kruskal-Wallis test (P<0.05). The pastes and their components were classified in the following decreasing order of antimicrobial action: calcium hydroxide P.A., paste A, paste B and Copaifera langsdorffii Desfon oil. Calcium hydroxide P.A. showed significantly higher antimicrobial action than the pastes or their vehicles. No significant difference was observed between the two pastes in dentin bridge formation. Based on the microorganisms studied, it can be concluded that the pastes analysed showed similar antimicrobial potential but differed significantly from their individual components. No significant difference was observed in dentin bridge formation between the different pastes tested.
