The aim of this study was to evaluate if the presence of periodontal infections (PI) is associated with community-acquired pneumonia (CAP) in a group of patients admitted to a hospital. A total of 140 patients were enrolled in this case-control study, with 70 patients having CAP (case group) and the other 70 patients diagnosed with other systemic diseases (control group). A periodontal examination was carried out to assess pocket probing depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), and presence of bacterial plaque (BP). CAL and BOP showed higher scores in the case group over the control group. They were, respectively, 3.16 ± 2.43 mm and 0.33 ± 0.24 % for the case group, and 1.99 ± 2.23 mm and 0.25 ± 0.24 % for the control group (p < 0.05). High scores for BP were observed in both groups (case: 97.1 %; control: 98.6 %, p = 1.0000). Chronic periodontitis (CP) was more frequent in patients with CAP (case: 61.4 %; control: 41.4 %). The presence of moderate or severe CP increased the risk for CAP [odds ratio (OR) = 4.4, 95 % confidence interval (CI) = 1.4-13.8], even when adjusted for age, ethnicity, gender, and smoking. Moderate and severe chronic periodontitis were associated with CAP in this study.

When lesions in soft tissue reach the gingival margin, they can produce aesthetic defects during its permanence and after its removal. Periodontal plastic surgery allows the correction of the gingival contour using different techniques. This paper is a case report of a peripheral ossifying fibroma removal in the interproximal area of teeth 21 and 22 in addition to root coverage of the affected area through two surgical phases: keratinized gingival tissue augmentation surgery with free gingival graft concurrent with removal of the lesion and, in a second stage, root coverage by performing coronally advanced flap technique with a follow-up of five years. The initial results achieved, which were root coverage of 100% after 6 months, promoted an adequate gingival contour and prevented the development of a mucogingival defect or a root exposure with its functional and aesthetic consequences. After five years, the results showed long term success of the techniques, where the margin remained stable with complete root coverage and tissues were stable and harmonic in color.

OBJECTIVE: The aim of this study is to evaluate, through a questionnaire, patients' awareness and behavior regarding periodontal disease, as well as their perceptions of the importance of self-care in order to control the disease. METHODS: 50 male and female patients, age ranging between 31 to 67 years old, presenting moderate to advanced periodontal disease were submitted to a 26 question-survey which aimed to assess the following: the patient's profile, his knowledge and awareness of the periodontal disease ,the dental practioner's commitment as to inform the patient about the importance of the concepts and understandings of his own self-care related to the disease. After data tabulation, they were subjected to exploratory analysis by means of tables and graphics of distribution of frequencies. RESULTS: The data showed that most patients were unanimously aware of the presence of periodontal disease and it also demonstrated that if they follow the dentist's recommendations, there will be a better disease prognosis. About 94 to 96% of the participants in the sample showed a higher level of knowledge about the etiology, treatment and consequences of periodontal disease, and reported that such information came from dental professionals. CONCLUSION: It was concluded that the periodontal disease patient becomes motivated to promote his self-care when the dentist promotes a proper instruction.

Objectives and Background Sodium ascorbyl phosphate (SAP) is a hydrophilic and stable L‐ascorbic acid derivative, being converted by the cell phosphatases into free ascorbic acid (AA), which allows its sustained release in the medium. AA participates in the maintenance and healing of the periodontium. It presents a regulatory role of the osteoblastic activity, stimulating the deposition of collagen extracellular matrix followed by the induction of genes associated with the osteoblastic phenotype. It also acts in the elimination of reactive oxygen species, abundantly produced by defense cells in periodontal disease. The aim of this study was to evaluate the effect of SAP on osteoblast viability and differentiation. Methods Mouse preosteoblastic cells of the MC3T3‐E1 strain were used. Cell viability was assessed by the trypan blue dye exclusion assay and the expression of genes related to osteoblast differentiation by quantitative PCR. Collagen I secretion was evaluated by ELISA, and mineralized matrix formation was assayed by Alizarin red S staining. Results The results showed that SAP at concentrations from 50 to 500 µmol/L does not influence preosteoblast cell viability, but stimulates their differentiation, observed by the induction of RUNX2, COL1A1, and BGLAP2; by the higher secreted levels of collagen I; and also by the increase in the mineralization of the extracellular matrix in cells exposed to this agent at 200 or 400 µmol/L, compared with those not exposed. Conclusion By its stability and capacity to induce preosteoblastic cell differentiation, our results indicate that the incorporation of SAP into local release devices, membranes/scaffolds or biomaterials, could favor bone tissue formation and therefore periodontal healing.

Objective The aim of this study was to evaluate the prevalence of peri-implant mucositis, as well as hygiene care around implants and the correlation between keratinized gingiva and probing depth around implants. Methods RESUMOObjetivo O objetivo desse estudo foi avaliar a prevalência de mucosite, bem como os cuidados de higiene bucal ao redor de implantes e a correlação entre a faixa de gengiva queratinizado e a profundidade de sondagem nos implantes. MétodosForam avaliados 107 implantes dentários de 24 pacientes em atendimento na Faculdade de Odontologia São Leopoldo Mandic. Os implantes foram avaliados em relação à presença de sangramento, tecido queratinizado e tempo de instalação dos implantes. Além disso, foram obtidos dos voluntários, os dados demográficos, bem como informações sobre os cuidados e métodos de higienização utilizados na região dos implantes. ResultadosA prevalência de mucosite foi de 81,31% dos implantes. A média de porcentagem de sangramento obtida foi de 29,91%. Dos 107 implantes, em 52,34% havia presença de tecido queratinizado. Quanto ao uso de métodos auxiliares para controle de biofilme, 43% dos pacientes utilizavam fio dental, 26,71% utilizavam escova interdental e 20,56% utilizavam escova unitufo. Foi observada apenas uma fraca correlação negativa entre sangramento marginal e presença de tecido queratinizado (p< 0,001, r= -0,27). ConclusãoPode-se observar uma alta prevalência de mucosite ao redor dos implantes, o que evidencia a necessidade de uma maior conscientização dos profissionais quanto à orientação de higiene bucal e incentivo à promoção de saúde em pacientes que recebem reabilitação com implantes dentais, bem como mais estudos investigando o real papel do tecido queratinizado ao redor dos implantes.Termos de indexação: Implantação dentária.
