13. Immediate tooth replantation: root canal filling for delayed initiation of endodontic treatment
Abstract The aim of this study is to evaluate the action of paramonochlorophenol associated with Furacin followed by calcium hydroxide (CH) dressing in the control of inflammatory root resorption in cases of immediate tooth replantation with delayed endodontic treatment. A total of 28 incisors of 3 male dogs were extracted and replanted after 15 minutes, and

14. Anti-dentine Salivary SIgA in young adults with a history of dental trauma in deciduous teeth
Anti-dentin autoantibodies are associated with inflammatory root resorption in permanent teeth and are modulated by dental trauma and orthodontic force. However, it is not known whether deciduous tooth trauma can stimulate the development of a humoral immune response against dentin. The aim of this study was to evaluate the levels of salivary SIgA reactiv

15. Differential expression of immunologic proteins in gingiva after socket preservation in mini pigs
During healing following tooth extraction, inflammation and the immune response within the extraction socket are related to bone resorption. Objective : We sought to identify how the alloplastic material used for socket preservation affects the immune responses and osteoclastic activity within extraction sockets. Material and Methods : Using a porcine model,

16. New methodology for evaluating osteoclastic activity induced by orthodontic load
Orthodontic tooth movement (OTM) is a dynamic process of bone modeling involving osteoclast-driven resorption on the compression side. Consequently, to estimate the influence of various situations on tooth movement, experimental studies need to analyze this cell. Objectives The aim of this study was to test and validate a new method for evaluating osteoclast

17. Genotoxic potential of 10% and 16% Carbamide Peroxide in dental bleaching
Dental bleaching has become one of the most frequently requested esthetic treatments in dental offices. Despite the high clinical success observed with this procedure, some adverse effects have been reported, including a potential for developing premalignant lesions, root resorption and tooth sensitivity, especially when misused. The aim of this study was to

18. Evaluation of technical quality and periapical health of root-filled teeth by using cone-beam CT
Objective This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation. Material and Methods The sample for this study consisted of 242 patients (aging f

19. Delayed tooth replantation: MTA as root canal filling
MTA has been investigated as a root-end filling material. Its mechanism of action has some similarities to that of Ca(OH)2. The purpose of this study was to evaluate the repair process taking place in the delayed replantation of monkey teeth using calcium hydroxide and MTA as root canal filling materials. Five monkeys had their lateral incisors extracted and

20. Extreme root resorption associated with induced tooth movement: A protocol for clinical management
Nos casos em que os dentes têm apenas o terço cervical remanescente de uma reabsorção radicular externa induzida ortodonticamente: 1) Quais seriam os cuidados para que permaneçam na boca, com o menor risco possível de perda? 2) Quais seriam os cuidados na interpretação imaginológica desses casos, quanto à determinação precisa da perda radicular e

21. Resorption of roots of different dimension induced by different types of forces
Root resorption is a variable to be considered in induced tooth movement (ITM). It is related to root morphology and alveolar bone crest, and also to the types of forces exerted by mechanotherapy. This histometric study evaluated the predominance of root resorption among roots of different dimensions, following ITM with different types of forces and at diffe

22. Effects of medications and laser on induced tooth movement and associated root resorption: four key points
Para que a avaliação dos efeitos de medicamentos e da fototerapia na movimentação dentária induzida e reabsorções radiculares associadas seja livre de influências externas, propusemos quatro pontos fundamentais na aplicação dos modelos experimentais: 1) Se o objetivo for verificar a influência nas reabsorções radiculares, deve-se garantir que as

23. Ciclooxigenase-2 modula in vivo a expressão de marcadores da osteoclastogênese e genes envolvidos no metabolismo ósseo em resposta ao lipopolissacarídeo bacteriano / Ciclooxygenase-2 modulates in vivo the expression of osteoclastiogenesis makers and genes involved in bone metabolism in response to bacterial lipopolysaccharide
During an inflammatory response, several mediators are locally released in order to stimulate cellular and humoral immune response. Through the action of cyclooxygenase and lipoxygenase enzymes structural changes occur in the arachidonic acid chain leading to synthesis of prostaglandins or leukotrienes and lipoxins, respectively. Such mediators are responsib

24. Avaliação do efeito de implantes subgengivais do polímero ELVAX com equistatina. Estudo microscópico em dentes de ratos extraídos e reimplantados / Evaluation of the effect of subgingival implants of polymer ELVAX with echistatin: microscopic study on rats\ extracted and reimplanted teeth
This study aimed to microscopically investigate the effect on the dental resorptive process of subgingival implants of ELVAX polymer with peptide echistatin in reimplantation of upper incisors in rats. For this purpose, 42 animals were used and divided into groups with and without echistatin. Extra alveolar socket period was 30 and 60 minutes and post-surgic
