ABSTRACT
Spindle cell carcinoma, a rare variant of squamous cell carcinoma, has propensity to occur in the upper aero digestive tract, including the oral mucosa. In this oral pathology communication, we report the occurrence of this neoplasm in the left mandible as a large fleshy growth with destruction of bone in a 73-year-old Afro-Trinidadian female. The distinction of this tumor from other malignant spindle cell mesenchymal tumors is important. Selective sampling of this specimen for possible transitional areas of squamous and spindle cell appearance, immunohistochemical staining for cytokeratin, vimentin, and S-100 protein are helpful in establishing the diagnosis. According to the patient's insistence, debulking of the tumor was performed under general anesthesia. Eight months later the patient succumbed to the disease.
ABSTRACT
Dentinogenesis imperfecta (DI) is an inherited disorder that affects dentin and often manifests as tooth discoloration; in addition, the dentition is also extremely susceptible to wear. Treatment of DI focuses primarily on protecting affected dentin, reducing sensitivity, and improving esthetics. Routine restorative materials, such as amalgams and composites, may be used. In more severe cases, the treatment of choice is full coverage crowns, while bonding of veneers may be used to improve the esthetics of the anterior teeth. This study presents two cases of Type II DI in the same family and the management of each case. Restorative management included amalgams, composite veneers, crowns, bridges, and overdentures.

AIM: To report the results of a survey of all percutaneous injuries occurring in 2003-2004 to staff and students at the dental school in Trinidad. METHOD: Data were collected via 163 questionnaires administered to all dental surgery assistants, the current clinical students (years 3, 4 & 5), the interns, part-time and full-time academic staff. RESULTS: A 71% response rate was obtained. The number of persons reporting one or more sharps injuries at the dental school was 42 (37%). Of these, 17 (40%) were percutaneous. Needlesticks and periodontal scaler injuries were the most common. There was no significant correlation (p>0.05) between injury and gender, age group, dominant hand or needle recapping technique. 75% of respondents described their concern of contracting a blood-borne disease from a sharps injury as "high" and 59% of the respondents followed the school's recommended protocol following the injury. 50% of the injuries among the students and interns were not reported. CONCLUSIONS: A more rigorous programme of risk management with respect to sharps injuries needs to be designed and implemented at the school. There is also a need to improve surveillance of and reduce the underreporting of these injuries.
