Current state about root coverage using soft-tissue substitutes in the presence of noncarious cervical lesions: A literature review.

About half of the cases of gingival recession are associated with the noncarious cervical lesion (NCCL), resulting in combined defects (CDs). NCCL negatively affects the root coverage outcomes. In addition, considering the morbidity associated with graft harvesting, soft-tissue substitutes (STSs) appeared as a suitable option for connective tissue grafts for surgical root coverage. Currently, the literature addressing the therapy of CDs employing STSs is scarce. Thus, the present review aimed to update the literature and outline the future perspectives about root coverage of CDs using STSs. A detailed literature search was conducted on MEDLINE, Web of Science, EMBASE, LILACS, Scopus, and Google Scholar databases using keywords and Boolean operators. Randomized clinical trials (2) and case reports (6) were included. None of the selected studies reported any adverse effect using STSs. Based on the limited evidence available, we cannot state that STSs may benefit the periodontal clinical and patient-centered outcomes. Randomized controlled trials are needed to assess the long-term outcomes, surgical approaches, and restorative protocols.

Treatment of multiple recessions with collagen matrix versus connective tissue: a randomized clinical trial.

The objective of this study was to determine whether collagen matrix (CM) is an alternative to connective tissue graft technique (CTG) in the treatment of multiple gingival recessions (GR). The indication of CM for the treatment of multiple GR is not yet clear. More studies are needed to better understand this treatment modality, as an alternative to CTG. In this single-blind, split-mouth randomized clinical trial, fifteen patients with multiple Miller class I upper GR were selected and randomly assigned to control group (CTG) or test group (CM). Root coverage (RC) and patient-centered outcomes were evaluated at baseline and after 3, 6, and 12 months. A total of 82 GRs were treated. There was no significant difference regarding GR depth (GRD, primary outcome) between CTG (0.5 ± 0.9 mm) and CM groups (0.6 ± 1.0 mm) (p = 0.225). Percentage of RC was 82.14% in CTG and 77.7% in CM. Both groups demonstrated a gain in keratinized tissue width at 12 months (p < 0.05). Dentine hypersensitivity was effectively reduced in both groups. Postoperative pain was significantly higher in the CTG (p = 0.001). Esthetic satisfaction was high for both groups, with no significant difference (p > 0.05) between groups. After 12 months, both surgical treatments were able to promote RC, and GRD was similar in both CTG and CM groups.

Orthodontic treatment in patients with aggressive periodontitis.

INTRODUCTION: Aggressive periodontitis (AP) is a condition that promotes breakdown of the periodontal tissues in a short time. In severe cases, pathologic migration of teeth and tooth loss can occur, producing esthetic and functional problems for the patient. Orthodontic treatment may be recommended to restore esthetics and masticatory function. We assessed the effects of orthodontic movement in the periodontal tissues of treated patients with AP. METHODS: Ten subjects (ages 25.0 ± 5.22 years) with AP received periodontal treatment followed by orthodontic treatment. Maintenance sessions were performed monthly under a strict dental biofilm control. They were compared with 10 periodontally healthy subjects (ages 22.9 ± 5.23 years) who received orthodontic treatment. Probing pocket depth, clinical attachment level, bleeding on probing, and dental plaque index were measured at baseline, after orthodontic treatment, and after 4 months. RESULTS: Statistical analysis showed improvement in all clinical parameters between baseline and 4 months after orthodontic treatment: probing pocket depth (0.29 mm), clinical attachment level (0.38 mm), bleeding on probing (4.0%), and dental plaque index (11%). CONCLUSIONS: The periodontal parameters of the AP patients remained stable during orthodontic treatment under strict biofilm control.

Influência do tratamento periodontal na função endotelial da doença cardiovascular / The influence of periodontal treatment in the endothelial function of cardiovascular disease ­ a systematic review

Objetivo: diversos estudos epidemiológicos vêm estudando a associação entre doença periodontal e doença cardiovascular, defendendo a ideia de que a DP seria um fator de risco para a doença cardiovascular. A doença periodontal é uma inflamação crônica que está associada ao aumento de marcadores inflamatórios sistemicamente e interferência na função endotelial. Vale ressaltar que a inflamação e a função endotelial têm um importante papel na patogênese da aterosclerose. Material e métodos: pouca informação existe a respeito da influência do tratamento periodontal na doença cardiovascular, sendo assim, este trabalho consiste em uma revisão de literatura, através da busca no MedLine/Pubmed de ensaios clínicos randomizados que estudem a influência do tratamento periodontal nos marcadores da doença cardiovascular. Resultados: através deste trabalho, foi possível concluir que o tratamento periodontal parece exercer influência na melhora dos níveis séricos dos marcadores cardiovasculares. Conclusão: mais estudos são necessários para comprovar a real relação.

Objective: several epidemiological studies have investigated the association between periodontal disease and cardiovascular disease, defending the idea that the DP would be a risk factor for cardiovascular disease. Periodontal disease is a chronic inflammation which is associated with inflammatory markers increasing and systemically interference in endothelial function. It is noteworthy that inflammation and endothelial function play an important role in the pathogenesis of atherosclerosis. Material and methods: little information exists about the influence of periodontal treatment in cardiovascular disease; therefore this study consists of a randomized clinical trial literature review to study the influence of periodontal treatment on markers of cardiovascular disease, through search in MedLine/Pubmed. Results: through this work it was possible to conclude that the periodontal treatment looks to influence the improvement of the serious levels of the cardiovascular markets. Conclusion: more studies are necessary to verify the real relationship between them.

Antibioticoterapia como coadjuvante no tratamento periodontal não cirúrgico de pacientes diabéticos / Antibiotic therapy as an adjunct to non-surgical periodontal treatment in diabetic patients ­ a literature review

Objetivo: verificar se o uso de antibióticos sistêmicos, adjunto à terapia periodontal não cirúrgica, em pacientes diabéticos pode trazer benefícios adicionais no controle glicêmico e parâmetros clínicos periodontais. Material e métodos: após a busca nos bancos de dados PubMed e Lilacs, foram incluídos nove ensaios clínicos randomizados para essa revisão da literatura. Resultados: nos desfechos periodontais, seis dos nove ensaios clínicos encontraram algum benefício a favor da antibioticoterapia. Quanto ao controle glicêmico, a maioria dos estudos falhou ao tentar relacionar o uso de antibióticos a uma maior redução da hemoglobina glicada. Conclusão: com base nesta revisão, concluiu-se que o uso de antibióticos sistêmicos em conjunto com o tratamento periodontal não cirúrgico pode oferecer benefícios adicionais, quando comparado ao tratamento periodontal sozinho, no tratamento da periodontite em pacientes com diabetes. Não há evidências de que a antibioticoterapia possa contribuir no controle glicêmico desses pacientes, sendo necessários mais estudos clínicos.

Objective: to verify whether systemic antibiotic therapy along with non-surgical periodontal management in diabetic patients can bring additional benefi ts on the glycemic control and periodontal parameters. Material and methods: after an electronic search on Medline and Lilacs databases, 9 RCTs were included. Results: six articles found favorable outcomes for periodontal clinical parameters. Regarding the glycemic control, most studies failed to prove a relationship between antibiotic use and the reduction on glycated hemoglobin levels. Conclusion: within the limits of this review, it can be concluded that systemic antibioticotherapy added to non-surgical periodontal treatment can bring additional benefits when compared to non-surgical treatment alone for diabetes-affected periodontal patients. However, there is no evidence that antibiotics can contribute to the glycemic control and more studies are necessary on this subject.

O efeito da sinvastatina na osseointegração / The effect of simvastatin on osseointegration ­ a literature review

O crescente aumento de instalações de implantes dentais com carga imediata e de suas fixações em tecido ósseo de baixa densidade tem gerado a necessidade real de aceleração e aprimoramento do processo de osseointegração, e muitos métodos e técnicas têm sido propostos para solucionar este problema. Neste contexto, a presente revisão teve por objetivo discutir os principais aspectos do papel da sinvastatina como intervenção para a melhoria no processo de osseointegração. Os resultados indicaram que a sinvastatina apresentou efeitos positivos em estudos experimentais, sendo necessários ensaios clínicos randomizados.

With increasing applications of dental implants with immediate loading and their installation in low quality bone, there is a real need to speed up and improve the osseointegration process. This review aimed to discuss the use of simvastatin in improving the osseointegration. The results indicate that simvastatin showed positive results in experimental studies, although randomized clinical trials are necessary.

Cooperação consciente: programas de motivação aos retornos periódicos periodontais: revisão de literatura / Compliance: motivation programs to periodic periodontal recalls: literature review

Após o tratamento periodontal ativo, a saúde periodontal é alcançada devido à eliminação ou controle da infecção. Porém, indivíduos que desenvolveram periodontite possuem grande risco de apresentar recorrência da doença, mesmo após um efetivo tratamento periodontal ter sido realizado. Para que o paciente possa manter em longo prazo o estado de saúde obtido com o tratamento, é necessário que se mantenha um programa de manutenções periódicas, com rechamadas em intervalos de tempo regulares, de acordo com a necessidade de cada caso. Este controle e manutenção profissional constituem o único meio de garantir os efeitos benéficos do tratamento e, consequentemente, a sobrevida da dentição. Em geral, o grau de cooperação dos pacientes a estes retornos, entretanto, é bastante baixo. Alguns métodos de motivação foram propostos na literatura para esta finalidade, e esta revisão bibliográfica se propõe a encontrar métodos efetivos de motivação e que possam ser aplicados na clínica periodontal para que um maior número de pacientes colaborem com o programa de controle e manutenção proposto. O envio de cartas e a realização de telefonemas são métodos bastante recomendados. Além disso, a constante estimulação do paciente através de reforços positivos, e principalmente a explicação ao paciente sobre a importância da terapia de manutenção são outros métodos de motivação sugeridos na literatura.

After active periodontal therapy, periodontal health is obtained due to infection elimination or its control. However, individuals who developed periodontitis have greater risk in presenting recurrent disease, even after an effective periodontal treatment. So in order that the patient can maintain and build upon the preceeding periodontal treatment, it is necessary to maintain a periodic maintenance program, with recalls in regular intervals of time, in accordance to the necessity of each case. This professional control and maintenance constitutes the only method to guarantee the beneficial effects of the treatment and, consequently, the dentition maintenance. In general, patient compliance with periodontal maintenance is, however, poor. Some methods of motivation were proposed in the literature for this purpose, and this bibliographical revision aimed to find effective motivation methods applicable in periodontal practice in order to have greater number of compliance patients in the maintenance program proposed. Sending letters and making phone calls are known to be very successful methods. Moreover, the constant stimulation of the patient through positive reinforcements and, mainly, the explanation for the patient about the maintenance therapy importance is another motivation method suggested in the literature.

Avaliação dos parâmetros clínicos periodontais em pacientesportadores de periodontite agressiva submetidos a tratamento ortodôntico / Evaluation of clinical periodontal parameters in patients with aggressive periodontitis after orthodontic treatment

A proposta deste trabalho foi avaliar em pacientes portadores de Periodontite Agressiva (PA) os parâmetros clínicos periodontais antes da movimentação ortodôntica, imediatamente após seu término e quatro meses após seu término.Participaram do estudo vinte pacientes dos gêneros masculino e feminino, não fumantes, divididos em dois grupos (Grupo Teste -10 pacientes portadores de PA;Grupo Controle – 10 pacientes periodontalmente saudáveis). Todos pacientesreceberam movimentação ortodôntica sob rigoroso controle mecânico do biofilmerealizado bimestralmente durante todo o tratamento ortodôntico. Foram avaliados osseguintes parâmetros clínicos: profundidade clínica de sondagem, junção esmaltecemento – margem gengival, nível clinico de inserção, sangramento a sondagem eíndice de placa bacteriana. Estes parâmetros foram mensurados por um único examinador cegado e calibrado, em três momentos (pré-ortodontia; pós-ortodontia;pós 4 meses da ortodontia) Após análise estatística (p<0,05), houve reduçãosignificativa para SS e IP apenas para o grupo teste. Na medição de 4 meses apósortodontia, os pacientes do grupo teste apresentaram melhoras significativas para osparâmetros PCS, JEC-MG e NCI. No grupo controle, a melhora estatisticamente significativa somente não ocorreu no parâmetro JEC-MG. Para ambos os grupos,nos molares, observamos melhora significativa do NCI em função da redução daPCS. Nos pré molares o mesmo ocorreu, porém, somente para o grupo teste...

The aim of this research was to evaluate periodontal clinical parameters inorthodontically treated patients with aggressive periodontitis. Twenty subjects of bothgenders, non-smokers, where divided in group Test (10 patients with aggressiveperiodontitis) and control (10 periodontally healthy subjects). All individuals were submitted to orthodontic treatment, under strict biofilm control every 2 months duringthe entire duration of the treatment. The following clinical paramenters were assessed: pocket depth; gingival recession, clinical attachment level, bleeding onprobing and dental plaque index. All clinical parameters were monitored before orthodontic treatment (baseline), immediately after the completion of the orthodontic movimentation, and 4 months post-treatment by a masked calibrated single examiner. Statistical analysis disclosed a significant (p<0,05) reduction of bleeding on probing and plaque index for the test group only...

Orthodontic extrusion with or without circumferential supracrestal fiberotomy and root planing.

The aim of this randomized clinical trial was to carry out a biometric comparison between the orthodontic extrusion (OE, group B) technique and OE combined with fiberotomy and root planing (OEFRP, group A). Twenty single-root teeth were extruded and assigned to two different groups. In both groups, fixed orthodontic appliances were activated weekly during the course of 3 weeks. After activation, the extruded teeth were maintained in retention for a period of 8 weeks. In group A, along with weekly activation, fiberotomy and root planing were carried out on the top of the alveolar bone crest. Statistical analysis revealed that the amount of dental structure exposed was greater in group A, where the gingival margin and bone tissue remained stable (P < .05). Group B presented coronal migration of the gingival tissue and bone tissue of 2 mm and 1.5 mm, respectively.

Aplicação do laser de Co2 em gengivoplastia e gengivectomia / The use of Co2 laser in gingivoplasty and gingivectomy

O objetivo deste estudo foi avaliar; com o auxílio de Informações contidas na literatura, os aspectos técnico-científicos da aplicação do Ia ser de dióxido de carbono (CO2) nas cirurgias de gengivectomia e gengivoplastia. O laser; desde a sua descoberta por MAIMAN, em 1960, foi adaptado e aplicado em diversas áreas do conhecimento, entre elas. na Odontologia. As aplicações em periodontia envolvem. entre outras, a cirurgia de tecido mole como a gengivoplastia e a gengivectomia. Esse laser tem a habilidade de cortar os tecidos com mínimo sangramento como nos cortes com bisturi a frio e como conseqüência a região operada é mais bem visualizada, o local sob intervenção não é, contaminado, o pós-operatório é mais bem suportado pelo paciente devido a dor e o edema serem minimizados, assim como não é necessária a utilização de Cimento cirúrgico. Conclui-se que o laser de CO2 pode ser usado em manobras cirúrgicas periodontais em gengivectomia e gengivoplastia principalmente em pacientes especiais. Em relação à técnica convencional o laser de CO2 , apresenta benefícios como sangramento mínimo durante o ato cirúrgico, redução da dor e edema pós-operatórios e rapidez na cicatrização dos tecidos moles operados, apesar do custo elevado do equipamento.
