This study investigated whether enamel matrix derivative (EMD) contributes to root coverage of gingival recessions performed with acellular dermal matrix graft (ADMG) in smokers during a 12-month follow-up. A sample of 19 smokers presenting bilateral Miller Class I or II gingival recessions were included. Selected sites randomly received both ADMG and EMD (test) or ADMG alone (control). Probing depth, clinical attachment level, gingival recession height, keratinized tissue, and root coverage were evaluated. Mean gain in recession height (P < .05), sites with complete root coverage (P < .05), and percentage of root coverage (59.7% and 52.8%, respectively) favored the test group compared with the control group.

Purpose: The present study aimed to identify the systemic risk indicators associated with periimplant mucositis and peri-implantitis in individuals with implant-supported fixed prostheses. Materials and methods: In this cross-sectional study, clinical evaluations of periodontal and peri-implant conditions were performed by a single examiner in a sample of 71 volunteers with 360 implants. Peri-implant mucositis was defined as the occurrence of bleeding on probing in association with redness and swelling or suppuration, without bone loss. Peri-implantitis was defined based on a radiograph of bone loss = 3 mm and/or a probing depth ≥ 6 mm with bleeding and/or suppuration on probing. The systemic factors evaluated were obesity, hormone replacement therapy, osteopaenia and osteoporosis, high blood pressure and hypercholesterolaemia. Logistic models were applied to assess the associations between peri-implant diseases and systemic factors. Results: Mucositis and peri-implantitis were found in 83.1% and 16.9% of the individuals, respectively. The regression analysis showed that obesity (prevalence ratio = 5.23; 95% confidence interval, 1.91 to 96.83; P = 0.01) and high systolic blood pressure (prevalence ratio = 4.23; 95% confidence interval, 1.66 to 12.87; P = 0.03) were associated with peri-implantitis at the individual and implant levels, respectively. No systemic factor was associated with peri-implant mucositis (P ≥ 0.06). Conclusion: Obesity and high systolic blood pressure were associated with peri-implantitis, whereas no systemic factor was associated with peri-implant mucositis. Future prospective studies are required to confirm these as true risk factors. Patients with obesity and/or high systolic blood pressure could be informed of the likely association with peri-implantitis, preferably before implant placement. [ABSTRACT FROM AUTHOR]

The present experiment used cell culture to analyze the adhesion capacity of mouse mesenchymal bone marrow cells and rat periodontal ligament to different titanium surfaces. Grade II ASTM F86 titanium discs 15mm in diameter and 1.5mm thick were used and received 2 distinct surface treatments (polished and cathodic cage plasma nitriding). The cells were isolated from the mouse bone marrow and rat periodontal ligament and cultured in α-MEM basic culture medium containing antibiotics and supplemented with 10% FBS and 5% CO2, for 72 hours at 37ºC in a humidified atmosphere. Subculture cells were cultured in a 24-well plate with a density of 1 x 104 cells per well. The titanium discs were distributed in accordance with the groups, including positive controls without titanium discs. After a 24-hour culture, the cells were counted in a Neubauer chamber. The results show that both the mouse mesenchymal bone marrow cells and rat periodontal ligament cells had better adhesion to the control surface. The number of bone marrow cells adhered to the polished Ti surface was not statistically significant when compared to the same type of cell adhered to the Ti surface treated by cathodic cage plasma nitriding. However a significant difference was found between the control and polished Ti groups. In relation to periodontal ligament cell adhesion, a significant difference was only found between the control and plasma-treated Ti surfaces. When comparing equal surfaces with different cells, no statistically significant difference was observed. We can therefore conclude that titanium is a good material for mesenchymal cell adhesion and that different material surface treatments can influence this process O presente trabalho utilizou a cultura celular para analisar a capacidade de adesão de células mesenquimais da medula óssea de camundongos e do ligamento periodontal de ratos a diferentes superfícies de titânio. Para tanto, foram utilizados discos de titânio grau II ASTM F86 nas dimensões de 15mm de diâmetro por 1,5mm de espessura, os quais receberam diferentes tratamentos de superfície em 2 grupos distintos (polido e nitretação a plasma por gaiola catódica). As células foram isoladas da medula óssea de camundongos e do ligamento periodontal de ratos e cultivadas em meio de cultura meio básico α-MEM contendo antibióticos e suplementado com 10% de FBS, por 72 horas, em atmosfera úmida com 5% de CO2 a 37ºC. No subcultivo as células foram cultivadas em 1 placa de 24 poços, na densidade de 1 x 104 células por poço, onde os discos de titânio foram distribuídos de acordo com os grupos, incluindo-se controles positivos sem os discos de titânio. Após 24 horas de cultivo, as células foram submetidas a contagem em câmara de Neubauer. Os resultados analisados mostraram que tanto as células mesenquimais da medula óssea de camundongos como as células do ligamento periodontal de ratos tiveram melhor adesão à superfície controle. O número de células da medula óssea aderidas a superfície de Ti polido não foi estatisticamente significante quando comparado ao mesmo tipo celular aderido à superfície de Ti tratada por plasma na configuração de gaiola catódica, entretanto diferença significante foi encontrada entre o grupo controle e o grupo Ti polido. Com relação à adesão das células do ligamento periodontal, diferença significativa foi encontrada apenas entre as superfícies controle e as superfícies de Ti tratadas por plasma. No que diz respeito às comparações entre superfícies iguais com células diferentes, não foi observada nenhuma diferença estatisticamente significante. Portanto, conclui-se que o titânio é um bom biomaterial para a adesão de células mesenquimais e que as diferentes formas de tratamento de superfície dada ao material podem influenciar neste processo

Aim: To evaluate the adhesion of mouse bone marrow mesenchymal cells (MBMMC) on different titanium surfaces. Methods: Grade II titanium discs (ASTM F86) received two different surface treatments: polished (S1) and cathodic cage plasma nitriding (S2). MBMMC were cultured on titanium discs in 24-well cell culture plates, at a density of 1 x 104 cells per well. After 24 h, the adhesion was evaluated using a hemocytometer. Results: The mean adhesion was greater on S2, though without statistically significant difference from S2 (p>0.05). Conclusions: It was demonstrated that titanium surface treatment with ionic nitriding in a cathodic cage is biocompatible since it preserved the integrity of the cultivated MBMMC for a period of 24 h, allowing their adhesion.

A terapia fotodinâmica antimicrobiana (TFDA) com cloro-alumínio ftalocianina (AlClFc) tem sido sugerida como adjuvante à terapia periodontal de raspagem e alisamento corono radicular (RACR), mas carece ainda de mais estudos clínicos. Objetivo: Avaliar a eficácia da TFDA com AlClFc nos parâmetros clínicos periodontais e níveis salivares de marcadores do estresse oxidativo - Glutationa (GSH) e Malondialdeído (MDA) - em pacientes com periodontite crônica. Metodologia: Este ensaio clínico, randomizado, duplo cego, paralelo, longitudinal e prospectivo, avaliou 22 pacientes: 14 no grupo teste (RACR+TFDA) e 8 no grupo controle (somente RACR). Cada paciente possuía no mínimo 2 sítios periodontais doentes (PS≥5mm), totalizando 63 sítios. A TFDA foi aplicada uma única vez logo após a finalização das sessões de RACR. Os índices de higiene bucal – índice de placa visível [IPV], índice de sangramento gengival [ISG], e os parâmetros clínicos periodontais - sangramento à sondagem [SS], profundidade de sondagem [PS] e nível de inserção clínica [NIC] - foram avaliados antes do tratamento no T0, e após os tempos de 3 meses (T3) e 6 meses (T6). Amostras de saliva foram coletadas em cada tempo de estudo para dosagem de GSH e MDA. Os dados foram analisados estatisticamente através dos testes não-paramétricos de Wilcoxon e Mann-Whitney, sendo préestabelecido um nível de significância de 5%. Resultados: A análise intragrupo demostrou diferença estatisticamente significativa entre os tempos T0, T3 e T6 (p

Mostra uma progressão rápida, agregação familiar e prevalência maior em melanodermos. A Terapia Fotodinâmica antimicrobiana (TFDa) representa uma proposta de auxiliar o tratamento mecânico local na descontaminação das superfícies radiculares. Objetivo: O objetivo deste trabalho foi avaliar a eficácia da TFDa associada à raspagem e alisamento radicular (RAR) em pacientes com Periodontite Agressiva generalizada(PA). Metodologia: Foram incluídos neste estudo clínico randomizado controlado cego do tipo “boca dividida” 16 pacientes acometidos por PA generalizada, com comprometimento periodontal similar em dentes contralaterais. Os arcos dentários foram aleatoriamente tratados exclusivamente com RAR no grupo controle, e com RAR associada à TFDa (660nm, 100mW, 10 segundos por sítio) com azul de metileno a 1% no grupo teste. Os pacientes entraram num programa de controle de biofilme. Os seguintes parâmetros clínicos foram avaliados por um examinador antes do tratamento e 90 dias após o mesmo: profundidade de sondagem (PS), distância da junção cemento-esmalte a margem gengival (JCE-MG), nível de inserção clínica (NIC), sangramento à sondagem (SS) e índice de placa (IP). Os dados foram analisados com o auxílio dos testes T pareado e Wilcoxon (p £ 0,05). Resultados: No pósoperatório de 90 dias, tanto o grupo teste quanto o grupo controle exibiram melhora na PS, e NIC (p≤0,001). Houve uma maior redução da profundidade de sondagem do grupo teste comparado ao grupo controle (p=0,05). O grupo teste também exibiu valores significativamente menores para o NIC final em comparação ao controle (p

- Abstract
Aim: The aim of this study was to evaluate the effect of indirect restorative materials (IRMs) and light-curing units (LCUs) on the micro hardness of dual-cured resin cement., Materials and Methods: A total of 36 cylindrical samples (2 mm thick) were prepared with dual-cured resin cement (Relyx ARC) photo-activated with either a QTH (Optilight Plus) for 40s or a LED (Radii) light-curing unit for 65s. Photo-activation was performed through the 2-mm- thick IRMs and the samples were divided into six groups (n=6) according to the combination of veneering materials (without, ceramic and indirect resin) and LCUs (QTH and LED). In the control group, the samples were light-cured with a QTH unit without the interposition of any restorative material. Vickers micro hardness test was performed on the top and bottom surfaces of each sample (load of 50 g for 15 secs). The data were statistically analyzed using a three-way ANOVA followed by Tukey x s post-hoc test ( P < 0.05)., Results: There were no statistically significant differences on the top surface between the light curing-units ( P > 0.05); however, the LED provided greater hardness on the bottom surface when a ceramic material was used ( P < 0.05). The mean hardness in photo-activated samples, in which there was no interposition of indirect materials, was significantly greater ( P < 0.01)., Conclusions: It may be concluded that the interposition of the restorative material decreased the micro hardness in the deeper cement layer. Such decrease, however, was lower when the ceramic was interposed and the cement light-cured with LED.
