Reabilitação de maxila atrófica com implantes zigomáticos: relato de caso

RFO UPF; 25 (1), 2020
Introdução: maxilas severamente atrofiadas representam um desafio às reabilitações implantossuportadas. A reconstrução maxilar com enxertos ósseos para permitir a reabilitação com implantes osseointegrados é um tratamento com boa previsibilidade e alto índice de sucesso. No entanto, a morbida...

Pam2CSK4 (TLR2 agonist) induces periodontal destruction in mice

Abstract Lipoproteins are important bacterial immunostimulating molecules capable of inducing receptor activator of nuclear factor-κB (RANKL) and osteoclast formation in vitro and in vivo . Although these molecules are present in periodontopathogenic bacteria, their role in periodontitis is not know...

Split crest technique for implant treatment of agenesis of the upper lateral incisors: results of a randomized pilot histological and clinical study at 24-month follow-up

Abstract Agenesis of lateral incisors, besides the functional issues, represents a great esthetic drawback. The selection of an appropriate treatment is a complex decision, which should consider the stability of the clinical outcomes over time. The aim of the present study was a histological and clinical...

Effects of vitamin C local application on ligature-induced periodontitis in diabetic rats

J. appl. oral sci; 28 (), 2020
Abstract Objective: This study evaluated the effects of local vitamin C treatment on tissue advanced glycation end products (AGE), interleukin (IL)-6, 8-hydroxy-2-deoxyguanosine (8-OHdG), and matrix metalloproteinases (MMP)-8 in tissues; serum C-terminal telopeptide fragments (CTX); and alveolar bone lo...

Evaluation of the effect of topical and systemic ozone application in periodontitis: an experimental study in rats

J. appl. oral sci; 28 (), 2020
Abstract Objective: The goal of the present study was to determine the effect of systemic and topical ozone application on alveolar bone loss (ABL) by evaluating the effect of Hypoxia-inducible factor −1 alpha (HIF-1-α) and receptor activator of NF-kB ligand (RANKL)-positive cells on histopat...

Resposta imunoinflamatória na periodontite experimental induzida em ratos submetidos à quimioterapia e a dose oncológica de zoledronato

O objetivo do presente estudo é avaliar os efeitos da quimioterapia com Cisplatina (CIS) combinado ao uso de Zoledronato (ZOL) sobre os tecidos periodontais saudáveis e na progressão da periodontite experimental induzida em ratos. Foram utilizados 160 ratos machos, distribuídos em dois grupos sem per...

Assessment of alveolar bone pattern in obese and non-obese women, before and after bariatric surgery: a prospective cohort study

ABCD (São Paulo, Impr.); 33 (1), 2020
ABSTRACT Background: Bariatric surgery may have a negative impact on oral bone structure. Aim: To verify the alveolar bone pattern through radiomorphometric indices of panoramic radiography and linear measurements performed in periapical radiographs in eutrophic and morbidly obese patients before and a...

Prevalence of horizontal alveolar changes in edentulous patients: a retrospective tomographic study

Abstract Horizontal bone loss after tooth extraction is a common finding that demands bone reconstruction in various cases. The aim of this study was to assess the horizontal alveolar status in partially and completely edentulous patients using cone-beam computed tomography (CBCT). In total, 1516 CBCT sc...

Avaliação tomográfica e histomorfométrica do uso da fibrina rica em plaquetas e leucócitos na cicatrização alveolar após extração dentária: um ensaio clínico randomizado

O uso dos concentrados plaquetários tem sido amplamente estudado em procedimentos cirúrgicos bucais. Entretanto ensaios clínicos randomizados com avaliação histomorfométrica e baixo risco de viés não são encontrados na literatura. Um ensaio clínico randomizado, controlado, cegado e paralelo foi...
