Uso de hialuronidato de sódio para tratamento de deslocamento anterior de disco articular com travamento bucal / Use of sodium hyaluronate in the treatment of disc displacement and closed lock

As desordens da articulação temporomandibular (DTM), causando limitações de abertura bucal e dor, podem estar relacionadas com a restrição do deslizamento ou do deslocamento para diante do côndilo mandibular, causado pela aderência do disco à fosse. A artrocentese é lavagem da articulação, sendo considerado um processo simples que proporciona bons resultados em pacientes que apresentam esses sintomas. Este artigo apresenta um caso de deslocamento anterior de disco da ATM em que a paciente cita como queixa principal limitação aguda da abertura da boca, acompanhada de dor...

Temporomandibular joint disorders causing limitation of mouth opening and pain may be related to the restriction of slipping or foward displacement of the mandibular condyle. Temporomandibular arthrocentesis is the lavage of the joint and is regarded as a simple method that produces good results in pacients wwith these symptoms. This article reports a case of disc displacement and closed lock in a pacient who reported limited mouth opening and pain as the main symptoms...

Influence of diameter and length of implant on early dental implant failure.

PURPOSE: To relate diameter and length of implants with early implant failure. PATIENTS AND METHODS: Implants with a cylindrical design and surface treatment by removal of titanium via acidification from 3 different manufacturers were used in this study. Two surgical procedures for submerged implants were evaluated--the placement of the implants (first surgical phase) and the procedure for reopening (second surgical phase)--before the installation of the prosthetic system. The length of the implants was classified as short (6-9 mm), medium (10-12 mm), or long (13-18 mm), and the diameter was classified as narrow, regular, or wide. The statistics were computed with SAS statistical software (SAS Institute, Cary, NC). Step-wise and chi(2) analyses were used, in addition to univariate and multivariate logistic regression. RESULTS: In this retrospective study, 1,649 implants (807 maxillary and 821 mandibular) were placed in 650 patients (mean age, 42.7 years) in different areas: anterior maxilla (458), posterior maxilla (349), anterior mandible (270), and posterior mandible (551). The early survival rate for all 1,649 implants was 96.2%. Regarding diameter, the largest loss was observed in narrow implants (5.1%), followed by regular (3.8%) and wide (2.7%) implants. Regarding length, the largest loss was observed in short implants (9.9%), followed by long (3.4%) and medium (3.0%) implants. Early loss occurred in 50 implants, 31 (4.3%) of which were installed in anterior areas and 19 (2.8%) in posterior areas. According to step-wise analyses and the chi(2) test, short implant (P = .0018) and anterior installation of implant (P = .0013) showed associations with early loss. CONCLUSION: A significant relationship of early implant loss was observed with short implants. No relationships between early loss of implants and the osseous quality or diameter of implants were observed. These findings may be attributed to the operator's experience with different implant designs, learning curves, or changes in technique and indications for the use of short implants from 1996 to 2004.

Treatment of mandibular glandular odontogenic cyst with immediate reconstruction: case report and 5-year follow-up.

Glandular odontogenic cysts of the jaw are rare with unusual histopathological features, well-defined limits, and a high recurrence rate when treated conservatively. We describe a 37-year-old white man with such a cyst of the right mandible that was resected, and at follow-up 5 years later there were no signs of recurrence.

Treating oral histoplasmosis in an immunocompetent patient.

BACKGROUND: Histoplasmosis is a deep fungus infection that occurs worldwide and is caused by Histoplasma capsulatum. Oral histoplasmosis has been of considerable importance in recent years because it occurs frequently in immunosuppressed patients, more often in those who test positive for the human immunodeficiency virus (HIV). However, the literature contains reports of histoplasmosis in immunocompetent patients, especially in endemic areas. CASE DESCRIPTION: The authors describe a case of an HIV-negative, immunocompetent 60-year-old man with ulcerative and painful oral lesions. The clinician included squamous cell carcinoma and systemic mycosis in the differential diagnosis. After the patient underwent a biopsy and a definitive diagnosis was reached, his initial treatment regimen included itraconazole (200 milligrams per day for one month), nystatin and chlorhexidine mouthrinse (0.12 percent, 10 milliliters, two times a day). The itraconazole treatment was continued for three more months (100 mg daily) until the lesions had resolved completely. CLINICAL IMPLICATIONS: Clinicians need to conduct a careful clinical evaluation and make an accurate diagnosis of ulcerated oral lesions. Knowledge of the oral manifestations of histoplasmosis may enable clinicians to reach a diagnosis earlier and initiate therapy more quickly.
