RESUMO
Microvascular free flap reconstruction of maxillectomy defects has been advocated as a more desirable treatment option than conventional prosthetic rehabilitation. Free flap reconstruction can successfully separate the oral and sinonasal cavities, but the reconstructed defect may not improve the treatment outcome when compared with conventional prosthetic rehabilitation of a nonsurgically reconstructed defect. In this report, the prosthetic management of a patient who underwent immediate microvascular free flap reconstruction of a unilateral maxillectomy defect is described, and the issue of surgical versus nonsurgical reconstruction is discussed.

PURPOSE: The objective of this study was to determine the severity, distribution, and correlates of tooth wear in a sample of Mexican-American and European-American adults drawn from a community-based longitudinal aging study on oral health. MATERIALS AND METHODS: The maxillary teeth of 71 subjects enrolled in a longitudinal aging study were assessed using a previously introduced five-point (0 to 4) ordinal scoring system in which each tooth is given a score describing the severity of wear. The tooth wear scores were compared with data concerning demographic factors, functional/parafunctional habits, soft drink consumption, and bite force measurements to determine specific correlates of tooth wear. RESULTS: The mean wear score for all teeth was 1.50 on the five-point scale. There was a significant difference between the mean wear score of anterior teeth (1.85) and posterior teeth (1.17). Bivariate analyses detected a moderate degree of correlation between maxillary tooth wear and age and bite force. Maxillary tooth wear was significantly greater in males and in subjects with reported teeth clenching/grinding. Multivariate analyses revealed that age, gender, bite force, self-reported teeth clenching/grinding, and number of daily meals/snacks had significant correlations with maxillary tooth wear. CONCLUSION: The overall severity of maxillary tooth wear in this sample of Mexican-American and European-American adults was low, with anterior teeth having a greater degree of wear than posterior teeth. Age, gender, bite force, teeth clenching/grinding, and number of daily meals/snacks are potential factors that may have contributed to tooth wear in the study sample.

A method of preventing tongue biting with a removal device has been described in this clinical report. Restraint of the tongue may be necessary to promote healing by preventing repetitive tongue biting or as a preventive measure after a surgery or an injury. Any device that is used to restrain the tongue should be removable to avoid prolonged interference with oral hygiene, swallowing, mastication, and speech. A removable device is desirable for long-term use by comatose or semicomatose patients.

Ectodermal dysplasia is commonly a difficult condition to manage with prosthodontics because of the typical oral deficiencies and because the afflicted individuals are quite young when they are evaluated for treatment. It is important that these individuals receive dental treatment at an early age for physiologic and psychosocial reasons. This article reviews the literature that pertains to the prosthodontic treatment of the disorder and the review includes considerations in behavior management and timing of treatment.

An occlusally worn or broken-down denture can present problems for the patient who must wear it and challenges for the dentist who must correct the condition. Many times an alternative to replacing the denture must be found. A method of restoring the occlusal surface of a worn or broken-down complete-arch fixed implant prosthesis is described.

Microbiologic isolation techniques and scanning electron microscopy were used to determine whether a fungus is associated with the black discoloration of some silicone nasal prostheses. Colonies of fungal growth were seen on scanning electron micrographs of the affected areas of a nasal prosthesis, and a fungus belonging to the genus Penicillium was isolated from similar areas. Disk diffusion tests determined that the antifungal agent clotrimazole, when incorporated into silicone samples, was effective in inhibiting in vitro growth of the fungus.
