Replantation is an acceptable option for treatment of avulsed permanent tooth. Nevertheless, extended extraoral period damages the periodontal ligament and results in external root resorption. The purpose this study was to assess by histologic histometric analysis, influence propolis 15% (natural resinous substance collected Apis mellifera bees from various plants) fluoride solution used as surface on healing process after delayed tooth replantation. Thirty Wistar (Rattus norvegicus albinus)...

Abstract – Success of tooth replantation is limited because part the replanted lost progressive root resorption. This study used histomorphometry and immunohistochemistry to evaluate effect low-level laser therapy (LLLT) on healing process rat teeth after different extra-oral periods, simulating immediate delayed replantation. Sixty Wistar rats (Rattus norvegicus albinus) had their maxillary right incisors extracted randomly assigned six groups (n = 10): C4, C30 C45, in which were 4 min...

This study presents results 6-year survey occurrence characteristics dental in patients admitted Service Surgery Oral Maxillofacial Traumatology School Dentistry Araçatuba (UNESP, Brazil) after emergency care hospital facilities region Araçatuba, SP, Brazil. For such purpose, clinical files treated at between 1999 2005 were reviewed....

Dental trauma is more common in young patients and its sequelae may impair the establishment accomplishment of an adequate treatment plan. This paper reports a case complicated crown-root fracture adult that was treated using adhesive tooth fragment reattachment orthodontic root extrusion. Considering time elapsed to follow up, extension, amount remaining portion patient's low socioeconomic status, approach proposed for this provided good functional aesthetic outcomes. Clinical radiographic...

The aim of this study was to evaluate the volumetric stability deproteinized bovine bone after sinus augmentation, using cone beam computed tomography (CBCT) and three-dimensional (3D) analysis.Using a specific selection tool 3D reconstruction from InVesalius 3.0, analysis CBCT scans performed in patients undergoing elevation technique critical defects, bone. first scan immediately graft surgery (T1), second 8 months (T2).A total 13 met inclusion criteria retrospective study; 26...

This study assessed the occurrence and characteristics of oral maxillofacial infections in patients treated at a Brazilian emergency service during 7-year period. The clinical files all Oral Maxillofacial Surgery Traumatology Service Araçatuba Dental School, São Paulo State University, Brazil, between 2002 2008 were reviewed. From population 3645 this period, sample consisted 93 subjects who presented odontogenic infections. Data referring to patients' sex, age, medical history, etiology,...

Abstract – The major concern in the therapeutics of tooth replantation refers to occurrence root resorption and different approaches have been proposed prevent or treat these complications. purpose this study was evaluate tissue response delayed anterior rat teeth treated endodontically using calcium hydroxide, Sealapex, Endofill without placement gutta‐percha cones. Thirty rats had their right upper incisor extracted maintained dry storage for 60 min. After removal dental papilla, enamel...

As life expectancy increases, a larger number of elderly people require dental health care attention for implant-supported rehabilitation, with the aim restoring function and aesthetics oral cavity. Most these patients have lost their teeth long time ago, causing severe bone resorption maxillary sinus pneumatization. Therefore, current study aims to demonstrate, through description clinical case, treatment zygomatic implants as an option treating severely atrophic maxillas. In this study,...

Background: The paradental cyst is an odontogenic lesion of inflammatory origin that has few clinical signs and symptoms apart from recurring acute episodes. A well‐defined radiolucency associated with the roots or distal to crown may be seen radiographically. purpose this article report on different aspects two cases involving cysts. In first case, patient complained about pericoronitis. semilunar‐shaped aspect mandibular third molar was noted periapical radiograph. second patient's main...
