Canine distemper virus in a crab-eating fox (Cerdocyon thous) in Brazil: case report and phylogenetic analyses

Although canine distemper is enzootic worldwide and has a wide host range, there are no reports of canine distemper virus there are no reports of canine distemper virus provide information on virus phylogeny and histopathologic lesions. The objective of this study is report and describe canine distemper in a crab-eating fox (C. thous), with a focus oil the phylogeny of the virus strain and the histopathologic lesions in the animal.

Multidisciplinary approach for the treatment of a complicated crown-root fracture in a young patient: A case report

Crown-root fractures in permanent teeth cause esthetic and functional problems. This paper reports the case of a complicated crown-root fracture in the maxillary right central inc sor of a young patient who was treated with a multidisciplinary approach in two phases. A modified Widman flap, root canal therapy, glass fiber post cementation, and adhesive tooth fragment reattachment were performed shortly after an accident. Satisfactory esthetic and functional outcomes were obtained. However, the patient did not attend follow-up visits and returned after 7 years. During this second phase, the clinical and radiographic examination showed stability and adaptation of the fragment and good periodontal health conditions, but crown darkening and a radiolucent image associated with the root apex of the fractured tooth were also observed. The periapical lesion was surgically removed by apicoectomy, and the esthetics were recovered with a direct composite res n veneer on the traumatized tooth. (Quintessence Int 2011;42:729-735)

Tooth replantation after keeping the avulsed tooth in oral environment: case report of a 3-year follow-up

Clinical practice has shown that most avulsed teeth are replanted after an extra-alveolar time that compromises the prognosis of replantation. In cases of delayed replantation, the use of adequate media for storage and transportation of the avulsed teeth may improve this prognosis considerably. Difficulties inherent to accidental dental avulsion include the lack of immediate access to ideal storage media, which accentuates the importance of saliva as a viable and readily available option. The authors report the case of an accidentally avulsed permanent maxillary central incisor that was kept into the patient's oral cavity from the moment of trauma until its replantation, 90 min later. Three years of follow-up revealed absence of root resorption, ankylosis or abnormal mobility, which demonstrates the feasibility of keeping avulsed teeth in saliva, at least when more indicated storage media are not available immediately.

Correction of a Mucogingival Defect Using an Implant-Retained Postoperative Stent in a Severely Resorbed Mandible: Case Report

This case report describes a technique that uses a palatal mucosal graft and an acrylic resin postoperative stent in an attempt to increase the layer of keratinized tissue around osseointegrated implants in an atrophic mandible. During second-stage surgery a split-thickness labial flap is reflected and apically repositioned by being sutured onto the periosteum and connective tissue. A palatal mucosal graft is then sutured onto the recipient site. The stent is worn for at least 4 weeks following surgery. This procedure helps to eliminate mobility of the mucosa in the area, deepen the vestibule, and prevent muscle reinsertion. (Int J Periodontics Restorative Dent 2008;28:617-623.)

Combined periodontal, orthodontic, and restorative treatment of pathologic migration of anterior teeth: A case report

Pathologic tooth migration related to periodontal disease is a common chief complaint of periodontal patients. This paper describes the treatment of a case of severe periodontal disease and disfiguring pathologic migration of maxillary central incisors, which required a multidisciplinary approach. After conventional pert. odontal treatment was performed, the anterior diastema was closed using a combination of orthodontic therapy and restorative treatment. A 6-month follow-up examination of this case revealed resolution of the anterior pathologic migration, with gains in clinical attachment levels and a successful esthetic and functional final result.

Short report: Application of an alternative Aedes species (Diptera : Culicidae) surveillance method in Botucatu City, São Paulo, Brazil

One of the main problems with dengue is the control of Aedes aegypti, its major vector. In Brazil, the current control program for Ae. aegypti and Aedes albopictus populations includes larval density surveys. An interesting alternative is the use of a distinct index, the Premise Condition Index (PCI). This tool relates conditions of property, such as houses and yards, and the degree of shade with the occurrence of Aedes sp. oviposition, and is calculated as scores from 3 to 9. The lowest score indicates property in good condition and an unfavorable breeding environment, while the highest score indicates property at high risk for infestation by Aedes sp. The present study is based on the application of the PCI in an urban area of Botucatu, Brazil to confirm its effectiveness.

Screw Spreading: Technical Considerations and Case Report

The spreading system is an alternative technique to the Summers osteotome. The crest expansion technique is a less invasive procedure in which the facial wall expands after the medullary bone is compressed against the cortical wall. It improves the density of the maxillary bone, which allows for greater initial stability of implants. A specific screw instrument, the "spreader," achieved a controlled and standardized dilation of the bone horizontally. The use of spreaders to enhance the dental implant site is a highly predictable procedure. (Int J Periodontics Restorative Dent 2011;31:141-147.)
