Collision tumor of small cell carcinoma and squamous cell carcinoma of the maxillary sinus: Case report.

A collision tumor refers to the coexistence of two diagnostically distinct tumors in a common anatomic space. Collision tumors are rare in the oral and maxillofacial region. The present study reported on the case of an 82-year-old female with a collision tumor in the maxillary sinus consisting of small cell carcinoma (SmCC) and squamous cell carcinoma (SCC).

The prevalence of tonsilloliths and other soft tissue calcifications in patients attending oral and maxillofacial radiology clinic of the university of iowa.

Objective. The purpose of this study was to determine the prevalence of tonsiliths in patients attending the oral and maxillofacial radiology clinic of The University of Iowa and to determine if there is any correlation between the presence of tonsiliths and the presence of stones in other body tissues, ducts, or organs. Study Design.

Obesity: a review of its implications and considerations in oral and maxillofacial surgery.

Obesity is defined as the accumulation of fatty tissue to such a level that overall health might be adversely affected. It is a complex, multifactorial metabolic condition which develops from interactions of genetic and environmental factors. The prevalence of obesity is increasing at an alarming rate in many parts of the world including developing countries.

Prospective, randomized, open-label, pilot clinical trial comparing the effects of dexamethasone coadministered with diclofenac potassium or acetaminophen and diclofenac potassium monotherapy after third-molar extraction in adults.

Background: Patients who experience pain, swelling, and trismus after third-molar extraction are reported to experience a 3-fold higher rate of adverse effects (AEs) on quality of life compared with those who are asymptomatic after this surgery. Therefore, investigators emphasize the necessity for better control of this triad of sequelae. Steroids can reduce the risk for physiologic processes of inflammation, thereby suppressing the development of inflammation.

Ameloblastoma: analysis of 207 cases in a Nigerian teaching hospital.

Objective: The aim of the study was to review all the cases of ameloblastoma seen at the Oral and Maxillofacial Surgery Clinic of the Lagos University Teaching Hospital, Nigeria, between 1980 and 2003.

Methods And Materials: In this retrospective study, case files and biopsy reports of new cases of ameloblastoma covering a 24-year period were retrieved and analyzed for sex, age on presentation, histologic type, and site distribution.

Results: A total of 207 cases of ameloblastoma were seen in the given period.

Effects of co-administered dexamethasone and diclofenac potassium on pain, swelling and trismus following third molar surgery.

Background: The apparent interactions between the mechanisms of action of non-steroidal anti-inflammatory drugs (NSAIDS) and steroids suggest that co-therapy may provide beneficial inflammatory and pain relief in the absence of side effects. The aim of the study was to compare the effect of co-administered dexamethasone and diclofenac potassium (diclofenac K) with diclofenac K alone on the postoperative pain, swelling and trismus after surgical removal of third molars.

Patients And Methods: A prospective randomized double-blind study was conducted at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Nigeria.

Are sterile gloves necessary in nonsurgical dental extractions?

Purpose: The aim of the study was to compare the incidence of healing complications of extraction socket with the use of sterile or clean nonsterile gloves during nonsurgical dental extractions.

Material And Methods: This was a randomized prospective study conducted at the exodontia clinic of the Department of Oral and Maxillofacial Surgery of the Lagos University Teaching Hospital (Nigeria), between October 2002 and January 2003. Patients who were referred for nonsurgical extractions of permanent teeth and who satisfied the inclusion criteria into the study were randomly allocated into 2 groups.

Odontogenic tumors: a review of 319 cases in a Nigerian teaching hospital.

Objective: This study sought to determine the relative frequency of odontogenic tumors in a Nigerian population and to compare these data with previous reports.

Study Design: Records of patients seen at the Lagos University Teaching Hospital between January 1980 and December 2003, with histologic diagnosis of odontogenic tumors (based on World Health Organisation classification, 1992), were analyzed.

Results: Odontogenic tumors constituted 9.
