13. Alveolar bone healing process in spontaneously hypertensive rats (SHR): A radiographic densitometry study
Hypertension is one of the most important public health problems worldwide. If undiagnosed or untreated, this pathology represents a systemic risk factor and offers unfavorable conditions for dental treatments, especially those requiring bone healing. Objectives: The purpose of this study was to demonstrate, by analysis of bone mineral density (BMD), that th

14. Experimental alveolitis in rats: microbiological, acute phase response and histometric characterization of delayed alveolar healing
The pathogenesis of alveolitis is not well known and therefore experimental situations that mimic some features of this disease should be developed. OBJECTIVE: In this study, the evolution of the experimentally induced infection in rat sockets is characterized, which leads to clinical signs of suppurative alveolitis with remarkable wound healing disturbs. MA

15. Influence of bisphosphonates on alveolar bone density: a histomorphometric analysis
This study is a histomorphometrical analysis of the influence of the bisphosphonate alendronate on alveolar bone density. Eighteen male Wistar rats were randomly assigned to a control group (n = 9) that received no medication and an experimental group (n = 9) that received oral alendronate (1 mg/kg) from birth until euthanization at 3 months of age. Semi-ser

16. Effect of Atorvastatin in radiographic density on alveolar bone loss in wistar rats
O objetivo deste estudo foi avaliar o efeito da Atorvastatina (ATV) na perda óssea alveolar induzida em ratos. A periodontite foi induzida através da colocação de ligadura ao redor do segundo molar superior esquerdo de um total de 24 ratos Wistar machos (± 200 g). Grupos de 6 animais receberam por via oral solução Salina a 0,9% ou Atorvastatina (1, 3

17. Influencia dos hormonios tireoidianos na densidade ossea e na periodontite : estudo em ratos / The influence of thyroid hormones on bone density and periodontitis : a study in rats
Thyroid hormones play a critical role on bone metabolism. However, data regarding the effect of thyroid hormones alterations on mandibular bone density and on the progression of periodontal disease are limited. The aim of the present study was to evaluate, in rats, the influence of different serum levels of thyroid hormones on: (1) the bone mineral density a

18. Avaliação in vivo da densidade óssea ao redor de implantes osteointegráveis com diferentes plataformas / In vivo assessment of bone density around dental implants with different platforms
In regard of the high successful rates and the excellent outcome, dental implants become the first option in rehabilitation for dental loss. In this way the maintenance of soft peri-implant tissues came up as a new issue to consider especially when esthetic areas are being restored. Generally a bone loss of approximately 1,5 mm occurs after one year of denta

19. Correlation between mandibular bone quality factors and bone mineral density in brazilian women / Correlação entre fatores de qualidade ossea mandibular e densidade ossea mineral em mulheres brasileiras
Existem diversos métodos para avaliar a qualidade óssea através de sua densidade. Estes métodos variam no custo, disponibilidade e na dose de radiação. O cirurgião-dentista atua nos elementos dentários e nas estruturas de suporte dos maxilares e mandíbula, componentes do sistema estomatognático. Nas últimas décadas têm se pesquisado muito a resp

20. Alveolar bone changes caused by low level laser therapy during induced orthodontic movement on rats. / Alterações teciduais decorrentes da fotobiomodulação laser no movimento dentário induzido em ratos.
The use of laser phototherapy is considered an enhancement factor for bone repair as it stimulates microcirculation as well as the cellular metabolism. Regarding this, the purpose of this research was to assess histologic changes after the use of laser phototerapy during induced mesial tooth movement with 40g/F of the upper left first molars of young adult m

21. Imunolocalização de CSF-1, OPG e RANKL no periodonto relacionado ao esmalte de incisivos de ratos em erupção normal e contida / Immunolocalization of CSF-1, OPG and RANKL in the enamel-related periodontium of rat incisors in normal and immobilized eruption
In the rat incisors the face of the socket related to the enamel is resorpted continually on the inner side and formed on the outer side. A study accomplished at our laboratory showed that in rat incisors immobilized by a period of 18 days, there is a replacement of bone resorption in the face of the socket related to the enamel by bone formation, where oste

22. Influência da ingestão crônica de altas doses de cafeína na periodontite induzida por ligadura e na densidade e reparo ósseo em tíbias de ratos: estudo histométrico
Embora alguns estudos tenham demonstrado a influência negativa da cafeína sobre o metabolismo ósseo, os resultados ainda são controversos. Além disto, a literatura não apresenta relatos sobre o efeito desta substância no tecido ósseo periodontal. Os objetivos deste estudo foram avaliar os efeitos de altas doses de cafeína na periodontite induzida po

23. Avaliação radiográfica de enxerto ósseo xenogênico em alvéolos de terceiros molares inferiores não-irrompidos / Radiographic assessment of impacted mandibular third molar sockets filled with composite xenogenic bone graft
The aim of this study was to evaluate the radiographic aspect of bone healing filled with a xenogenic graft material (Gent-techTM). Thirty- nine patients, ranging from 15 to 25 years with bilateral impacted mandibular molars were chosen based on bilateral mandibular similarities. After tooth extraction, one socket was filled with experimental materials. The

24. Densidade ossea alveolar em mulheres com periodontite na pre e pos-menopausa
The aim of this study was to compare the alveolar bone density in pre and postmenopausal Caucasian women with chronic eriodontitis attending the clinic at Piracicaba Dental School - UNICAMP. Forty women were selected: 20 in pre menopause and 20 in post menopause. The study used a conventional periapical radiographic film adjusted with an equivalent aluminum
