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 – This study analyzed mineral trioxide aggregate (MTA) as a root canal filling material for the immediate reimplantation of monkey teeth. Four adult capuchin monkeys Cebus apella were used, which had their maxillary and mandibular lateral incisors on both sides extracted reimplanted after 15 min. During extra‐alveolar period, teeth kept in saline solution retention was performed with stainless steel wire composite resin 14 days. After 7 days, submitted to endodontic treatment...

Abstract – Minimal extraoral dry storage period and moist for the avulsed tooth are identified as key steps treatment protocol of replantation. Among possible media, bovine milk has stood out because its capacity preserving integrity periodontal ligament (PDL) fibers. This condition attracted attention to investigate use powdered milk, which is one presentation forms a feasible medium in cases delayed The aim this study was evaluate healing process after replantation rat teeth stored...

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...

Abstract – Clinical experience has shown that most avulsed teeth are replanted after a long extra‐alveolar time and dry or inadequate wet storage, causing necrosis of periodontal ligament cells. This condition invariably leads to development external root resorption, leaving the filling material in contact with periapical connective tissues. In this study, tissue reactions calcium hydroxide (CH) mineral trioxide aggregate (MTA) were evaluated occurrence resorption as an expected sequela...

Surgical treatment of panfacial fractures usually requires intraoperative temporary occlusion the teeth and simultaneous access to nasal pyramid. In such cases, standard method airway management is perform a tracheostomy, but this may be associated with significant number perioperative late complications. This study aimed determine if submental endotracheal intubation (SEI) viable alternative especially when short-term postoperative control foreseen. was an observational retrospective study,...

Dental trauma has been considered as a public health problem that affects mainly children and youngsters due to its impact on the patient's quality of life. 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....

Abstract – Dental tissues have special characteristics, and its regenerative capacity is noteworthy. However, understanding the circumstances that lead to regeneration challenging. In this study, chronology of healing process after immediate replantation rat incisor teeth was examined by histological immunohistochemical analyses within a 60‐day period. Thirty‐six male Wistar rats had their maxillary right incisors extracted replanted 15 min in saline storage. The were sacrificed immediately...

Abstract – Radicular fractures in permanent teeth are uncommon injuries among dental traumas, comprising 0.5–7% of the cases. Fracture occurs most often middle‐third root and rarely at apical‐third. The present paper reports a clinical case horizontal radicular fracture located between middle‐ apical‐third upper left‐central incisor followed‐up for over 3 years. tooth was extracted owing to periodontal reasons. Histomorphologically, it showed pulp‐vitality preservation healing by hard‐tissue...

Abstract – Although it has already been shown that enamel matrix derivative (Emdogain ® ) promotes periodontal regeneration in the treatment of intrabony defects, there is little information concerning its regenerative capacity cases delayed tooth replantation. To evaluate alterations healing replanted teeth after use Emdogain , central incisors 24 Wistar rats ( Rattus norvegicus albinus were extracted and left on bench for 6 h. Thereafter, dental papilla organ each sectioned pulp removal by...

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...

Accurate diagnosis and adequate treatment plan may constitute very complex tasks, particularly in tooth avulsion, because several variables are involved. In addition to the technical knowledge clinical experience directed toward quality of treatment, patient education favorably influence survival replanted teeth. The aim this study was analyze procedures used management avulsion by 100 dental surgeons (DSs). Thus, means a descriptive questionnaire, information obtained about profile...

Abstract – Traumatic tooth injuries involve function and aesthetics cause damage that range from minimal enamel loss to complex fractures involving the pulp tissue even of crown. Technical knowledge clinical experience are essential establish an accurate diagnosis provide a rational treatment. The purpose this study was evaluate Restorative Dentistry specialists about management crown crown–root based on treatment plans proposed by these professionals for cases. A descriptive questionnaire...

The purpose of this retrospective study was to analyze the cases traumatic dental injuries involving root fracture and/or periodontal ligament injury (except avulsion) treated at Discipline Integrated Clinic, School Dentistry Araçatuba, São Paulo State University (UNESP), Brazil, from January 1992 December 2002. Clinical and radiographic records 161 patients with 287 traumatized teeth that had sustained were examined. results survey revealed subluxation (25.09%) most common type injury,...

Abstract – Immediate replantation into the socket is ideal procedure in cases of accidental avulsion permanent teeth. In Brazil, firefighters with special paramedic training are charge providing first‐aid care to victims road accidents and might have deal tooth avulsions. This study assessed knowledge regarding emergency management avulsed Information was collected from a questionnaire submitted 110 volunteer seven cities São Paulo State (Brazil). The results revealed that 70.9% respondents...

Abstract The purpose of this study was to evaluate commercially pure titanium implant surfaces modified by laser beam (LS) and LS associated with sodium silicate (SS) deposition, compare them machined surface (MS) dual acid‐etching (AS) modified. Topographic characterization performed scanning electron microscopy–X‐ray energy dispersive spectroscopy (SEM–EDX), mean roughness measurement before surgery. Thirty rabbits received 60 implants in their right left tibias. One each tibia. were...

Background: Blood‐derived products, platelet‐poor plasma (PPP) and platelet‐rich (PRP), constitute an approach in the enhancement of tissue healing. PRP has also been used as a scaffold for bone marrow stem cells engineering. This study evaluates effect PPP, calcium chloride–activated (PRP/Ca), chloride– thrombin‐activated (PRP/Thr/Ca), mononuclear PRP/Ca (BMMCs/PRP/Ca) on healing replanted dog teeth. Methods: After 30 minutes extraction, teeth were with 1) no material (control); 2) PPP; 3)...

This study evaluated microscopically the effects of root surface treatment with three different solutions in delayed rat teeth replantation. Central incisors from 30 rats (Rattus norvegicus, albinus Wistar) were extracted and left on a bench for 6 h. The pulps extirpated canals irrigated 1% sodium hypochlorite. After endodontic treatment, surfaces all submitted to 10-min hypochlorite, changed every 5 min. then rinsed saline 10 min assigned 3 groups ten specimens each. Groups I, II III...
