ABSTRACT
Generalized stage IV, grade C periodontitis results in rapid bone destruction in the periodontium and can lead to early tooth loss. Scaling and root planing (SRP) complemented by systemic antibiotics, access surgery, regenerative techniques and implant placement are among the treatments used for patients with this condition. The aim of this article is to report a comprehensive periodontal treatment in a 23-year-old male who was referred to the periodontology department due to complaints of tooth mobility and gum infections diagnosed with generalized stage IV, grade C periodontitis according to the clinical, systemic, and family history features observed. Thorough non-surgical periodontal treatment consisting of scaling and root planing was provided, followed by a series of regenerative periodontal surgeries including guided tissue regeneration (GTR) and guided bone regeneration(GBR) to manage advanced bone defects. Six months after periodontal therapy, all implants were inserted using a one-stage approach and Six months later, they were restored with porcelain fused to metal crowns. During the one and two-year follow-ups, the teeth and implants did not show any signs of instability, attachment loss or bone loss. This case report shows that within the limitations of this study a successful outcome can be achieved with an early diagnosis and treatment involving elimination of infectious microorganisms and meticulous long-term maintenance combined with regenerative techniques and implant placement to restore the masticatory function and improve the quality of life for the patient. However further investigation and clinical studies are required to confirm these results (AU)
A periodontite generalizada estágio IV, grau C resulta em rápida destruição óssea do periodonto, podendo levar à perda dentária precoce. Raspagem e aplainamento radicular (SRP) complementada com antibióticos sistêmicos, acessos cirúrgicos, técnicas regenerativas e colocação de implantes estão entre os tratamentos usados para essa condição. O objetivo deste artigo é relatar o tratamento periodontal abrangente de um paciente de 23 anos, que foi encaminhado ao departamento de periodontia com queixas de mobilidade dentária e infecções gengivais, diagnosticado com periodontite generalizada estágio IV, grau C de acordo com as características clínicas, sistêmicas e de histórico familiar observadas. O tratamento periodontal não cirúrgico completo de raspagem e aplainamento radicular foi realizado, seguido por cirurgias periodontais regenerativas, incluindo regeneração tecidual guiada (GTR) e regeneração óssea guiada (GBR) para tratar defeitos ósseos avançados. Seis meses após a terapia periodontal, todos os implantes foram inseridos através de abordagem de estágio único e, seis meses depois, foram restaurados com porcelana fundida às coroas de metal. Durante os acompanhamentos de um e dois anos, os dentes e implantes não mostraram quaisquer sinais de instabilidade, perda de inserção ou perda óssea. Este relato mostra que, dentro das limitações deste estudo, um resultado bem-sucedido pode ser alcançado a partir de diagnóstico precoce e tratamento envolvendo a eliminação de microrganismos e manutenção meticulosa à longo prazo, combinada com técnicas regenerativas e colocação de implantes para restaurar a função mastigatória e melhorar a qualidade de vida do paciente. No entanto, mais investigações e estudos clínicos são necessários para confirmar esses resultados (AU)

PURPOSE: The purpose of the present study was to evaluate the efficacy of simvastatin administration as an osteoinductive agent combined with bovine bone material (BBM) for augmentation of human maxillary sinuses. MATERIALS AND METHODS: In the present randomized clinical trial with a split-mouth design, 24 maxillary sinuses in 12 patients were augmented using BBM alone or BBM combined with simvastatin. Biopsy samples were taken 9 months after maxillary sinus floor augmentation for histologic and histomorphometric analyses. A total of 44 implants were placed in the augmented bone. RESULTS: The results of the microscopic assessment of most samples revealed no inflammation or only mild chronic inflammation. Lamellation was detectable in old bone trabeculae under polarized light microscopy but was not observed in newly formed bone. Osteocytes were found with a lower frequency in the lacunae of newly formed bone compared with normal bone. No significant differences were found in the amount of newly formed bone and the amount of residual particles between the 2 groups. CONCLUSIONS: Despite the greater mean percentage of newly formed bone in the test group, the histomorphometric analysis results did not show a significant positive effect for the use of simvastatin in maxillary sinus augmentation.
