AFASIA MOTORA, PARALISIA FACIAL E HEMIPLEGIA DIREITA APOS ABSCESSO DENTARIO A ESQUERDA

The authors report a case of a 6 year old child who presented with dental abscess associated with a parietal and frontal cerebrite, right facial paralysis and motor aphasia. The clinical findings, radiological examination including computerized tomography and type of treatment are presented. At beginning, the patient did not respond to antimicrobial therapy and only after drainage of her dental abscess revealed good clinical evolution.

Peripheral ameloblastoma.

A case of peripheral ameloblastoma in a 57-years-old woman is presented, along with a discussion of the clinical and histological characteristics of the lesion. After clinical and radiographic examinations, and with a differential diagnosis of pyogenic granuloma, an excisional biopsy was performed and the material collected was sent for histological examination. On the basis of the histopathological diagnosis, a second operation was performed with a wide safety margin, including bone tissue, which did not show any involvement with the odontogenic neoplasm.

Apical and periapical repair of dogs' teeth with periapical lesions after endodontic treatment with different root canal sealers.

The aim of this study was to evaluate the apical and periapical repair after root canal treatment of dogs' teeth with pulp necrosis and chronic periapical lesion using different root canal sealers. After periapical lesion induction, forty-four root canals of 3 dogs were submitted to biomechanical preparation using 5.25% sodium hypochlorite as an irrigating solution. A calcium hydroxide dressing (Calen PMCC) was applied for 15 days and the root canals were filled using the lateral condensation technique with gutta-percha points and Sealapex, AH Plus or Sealer Plus for sealing. After 180 days, the animals were sacrificed by anesthetic overdose and the obtained histological sections were stained with hematoxylin-eosin for optical microscopic analysis of the apical and periapical repair. The groups filled with Sealapex and AH Plus had better histological repair (p < 0.05) than the group filled with Sealer Plus, that had unsatisfactory results.

Conservative treatment of a radicular cyst in a 5-year-old child: A case report

The present report describes the management of a radicular cyst in a 5-year-old child. The treatment comprised extraction of the primary teeth involved followed by marsupialization. A removable appliance with a resin extension penetrating into the cystic cavity was used to help decompress the lesion. This treatment allowed rapid healing of the lesion and eruption of the permanent incisors without the need for orthodontic treatment.

Naso-orbicular tissue necrosis by Streptococcus parasanguis in a patient with Fanconi anemia: Clinical and laboratory aspects

Fanconi anemia (FA) is a rare autosomal recessive disorder, characterized by pancytopenia and progressive hypoplasia of the bone marrow. A 23-year-old woman with FA showed severe pancytopenia and developed an abscess on the infraorbicular region on the right side of the face that progressed to phlegmon and caused tissue necrosis of the nostrils, nasal septum, nasal fossa, and posterior orbital region. Laboratory examination showed Streptococcus parasanguis as the etiologic agent of the phlegmon. Supportive treatment was recommended due to donor incompatibility for bone marrow transplant. The intraoral examination showed spontaneous gingival bleeding, edema of the interdental papillae, hematomas on the superior and inferior lips, bacterial and fungal infections, and adequate oral hygiene. The patient was treated with the administration of an antibiotic (imipenem), an antifungal (amphotericin B), and mouth washing with antiseptic solutions. Periodontal prophylaxis and orientation to and control of oral hygiene and diet were also used during the remission period. For functional and esthetic rehabilitation of the alar regions and nasal dorsum, an acrylic resin nasal prosthesis was made, supported by a spectacle frame.

Omentalisation as a treatment for prostatic cysts and abscesses

Seven dogs with prostatic retention cysts and three with prostatic abscess were referred for prostatic omentalisation and were discharged 72 hours later. Eight dogs had an uneventful recovery while one dog had a minor incontinence for two days. One dog died due to a previous long-term sepsis. The low incidence of post-operative complications and brief hospitalisation period make omentalisation the surgery of choice for the treatment of prostatic cysts and abscess.

Odontomas in pediatric dentistry: Report of two cases

Odontomas are developmental disturbances which manifest in the form of denticles or amorphous informes masses comprising all dental tissues, especially enamel and dentin, with variable amounts of pulp and cement. We describe here two clinical cases of odontomas in children, focusing on diagnostic means and the importance of early treatment of these lesions. The standard treatment for the two present cases was surgical removal.

Periodontal plastic surgery associated with treatment for the removal of gingival overgrowth

Background: Excisional biopsies of gingival overgrowths, performed with safety margins, frequently result in mucogingival defects. These defects may produce esthetic problems and increase the chances of dentin hyperesthesia and its possibility of hindering oral hygiene. Methods: Two clinical cases are reported in which gingival overgrowths were removed by excisional biopsy, resulting in unsightly defects. The first clinical case presents an invasive approach for the treatment of a recurrent pyogenic granuloma in the anterior maxilla, and the second depicts a complete removal of a peripheral odontogenic fibroma in the posterior maxilla. In both situations, the soft-tissue defects were repaired by periodontal plastic surgery, including a laterally positioned flap and a coronally positioned flap, respectively. Results: Periodontal plastic surgery successfully restored the defects that resulted from biopsies, and no recurrence has been noticed in the 5-year postoperative follow-up period. Conclusions: The combination of biopsy and periodontal plastic surgery in a one-step procedure seems to be suitable to remove gingival overgrowths in most areas of the mouth, regardless of esthetic significance. Such procedures seem to restore gingival health, encourage healing, and create both esthetics and function in the excised area.

Dentigerous cysts in primary dentition: Report of 2 cases

Dentigerous cysts are benign odontogenic cysts associated with the crowns of permanent teeth. They are usually single in occurrence and located in the mandible. The purpose of this case report was to describe the management of 2 dentigerous cysts in children. The treatments instituted were the extraction of the deciduous tooth involved followed by marsupialization in the first case and enucleation in the second one. Both treatments allowed rapid healing of the lesion and eruption of the permanent teeth without the need for orthodontic treatment.

Omentalização prostática em cãse

The prostate is the only acessory sex gland in the male dog and, although the prostate is found in all mammals, it has a great importance in men and dogs due to the frequency of disorders. Several techniques have been employed for the treatment of prostatic cysts and abscesses and, a few years ago, it was successfully described the use of prostatic omentalisation for this purpose; until now, there are no data about this surgery in Brazil. So, the aim of this study was to evaluate the animal recovery, as well as the post operative period of dogs that underwent prostatic omentalisation, from 2002 to 2004. It was evaluated 11 dogs with prostatic cysts, 4 dogs with prostatic abscesses and 2 with paraprostatic cysts. Fifteen dogs had an uneventful recovery while one dog had a minor incontinence for two days. One dog died due to a previous long term sepsis. The low incidence of post operative complications and brief hospitalization period make omentalisation the surgery of choice for the treatment of prostatic cysts and abscess.

Abscesso do músculo psoas em paciente submetida à analgesia por via peridural. Relato de caso

BACKGROUND AND OBJECTIVES: Psoas muscle abscess is a rare complication of epidural analgesia. The adequate approach to this complication is fundamental for a good resolution. The objective of this report was to discuss the diagnosis and treatment of psoas muscle abscess. CASE REPORT: A female patient, 65 years old, with neuropathic pain in the lower limbs, difficult to control with systemic drugs. The patient was treated with epidural opioid and local anesthetic as an alternate treatment. Twenty days after the continuous epidural administration, the patient complained of lumbar pain, headache, and fever. A CT scan of the pelvis showed an abscess of the psoas muscle, thus, closed drainage and antibiotics were indicated. CONCLUSIONS: An adequate, continuous supervision of the patient is necessary when an epidural catheter is placed, and it should continue after its removal. © Sociedade Brasileira de Anestesiologia, 2007.

Unusual wooden foreign body in the palate

We report a case of a palatal calcified foreign body simulating an odontogenic lesion. Surgical exploration revealed a calcified mass that was analysed under light microscopy and identified as a vegetal foreign body. Further scanning electron microscopy analysis revealed that the foreign body was a piece of wood. Hard palate foreign bodies have been reported previously, however, it seems that this is the first case of its kind. © 2007 Nature Publishing Group.

Conservative treatment of patients with periapical lesions associated with extraoral sinus tracts

This paper describes the clinical courses of three cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. All teeth involved had periradicular radiolucent areas noted on radiographic examination and extra-oral sinus tracts appearing on the chin with exudation and unpleasant aesthetic appearance. The adopted treatment protocol included treating the sinus tract surface simultaneously with the root canal therapy. After root canal shaping using 5.25% sodium hypochlorite solution, calcium hydroxide-based pastes associated with different vehicles were inserted into the root canal for 4 months, and were changed monthly. All the sinus tracts healed in 7 to 10 days. The apical lesions were completely repaired in a maximum period of 24 months. The treatment adopted provided a complete healing of the periapical lesions in a short follow-up period. Surgical repair of the cutaneous sinus tract was therefore unnecessary. © 2007 The Authors.
