Triamcinolone acetonide versus chlorhexidine for treatment of recurrent stomatitis.

This study compared the efficacy of pain control of two medications, used to treat recurrent aphthous stomatitis, placed under a physical barrier of cyanoacrylate. Thirty patients with recurrent aphthous stomatitis were selected from the records of the Diagnostic Referral Clinic at Indiana University School of Dentistry and randomly divided into three groups; one group was a control. Experimental groups received a topical application of either triamcinolone acetonide (0.025%) or chlorhexidine digluconate (0.12%). Medications were covered by isobutyl cyanoacrylate (Iso-Dent). Controls received the Iso-Dent only. Patients kept a diary to record their pain level on a 10 cm visual analog scale until the lesion healed. Ulcer episodes were treated for 12 weeks. Because some patients had multiple episodes, a total of 35 ulcer episodes were available for analysis. The mean number of ulcer days for each group was not significantly different. ANOVA with repeated measures for 10 days on each patient was first performed. A highly significant difference in pain intensity and perception was found at different days (p < 0.0001). No significant difference was found between the triamcinolone acetonide and chlorhexidine gluconate (p < 0.49).

Oral mucosal injury caused by denture cleanser tablets: A case report

A case of chemical injury to the oral mucosa that resulted in obstructive sialadenitis of the submandibular glands is presented. The injury occurred when a patient chewed, swished, and expectorated an immersion-type denture-cleansing tablet attempting to clean a fixed bridge. The literature is reviewed for similar oral mucosal injury caused by improper use of denture-cleansing products. Suggestions for the prevention of such injuries are made.

Hypodontia and nail dysplasia syndrome: Report of a case

The ectodermal dysplasias are a clinically and genetically heterogeneous group of more than 120 syndromes involving ectodermally derived structures. The syndrome that is autosomal dominantly inherited and characterized by hypodontia, dysplastic nails, and normal hair is known as hypodontia-nail dysplasia syndrome, or tooth-and-nail syndrome. Because of the minimal manifestations, this syndrome may be difficult to diagnose. Patients with hypodontia should be examined for dysplastic nails of the hands and feet and referred to medical and dental genetic specialists for verification of the diagnosis and counseling. We report a case of tooth-and-nail syndrome in a young woman.

Psoriatic involvement of the temporomandibular joint

An unusual case of bilateral psoriatic involvement of the temporomandibular joints with severe ankylosis is reported. A second case describing the typical destructive changes more commonly reported is presented for comparison.

Video enhancement of dental radiographic films

A prototype video image display system, a real-time analog enhancer (RAE), was compared to conventional viewing conditions with the use of nonscreen dental films. When medium optical density films were evaluated, there was no significant difference in the number of radiographic details detected. Conventional viewing conditions allowed perception of more details when dark films were evaluated; however, the RAE unit allowed the perception of more details when light films were viewed.

Information yield from a hand-held dental x-ray unit

The information yield from a hand-held radiographic unit was compared with that of a conventional dental x-ray unit. Ten observers were asked to detect radiographic details on films taken of a test object at eight different exposure settings with each radiographic unit. The viewers detected significantly more details on three films generated with the experimental unit. No significant difference was demonstrated in the number of details observed with either unit at the remaining exposure settings.

Clinical and radiographic features of the lacrimo-auriculo-dento-digital syndrome

Lacrimo-auriculo-dento-digital syndrome is an autosomal dominant malformation complex that affects craniofacial structures including the teeth and salivary glands. There have been several cases of this syndrome reported to date. A family with three affected members is presented. In addition to several of the clinical manifestations of lacrimo-auriculo-dento-digital syndrome, these subjects also show previously unreported radiographic features of the syndrome as demonstrated by panoramic radiographic examination and corrected axis linear tomography of the temporomandibular joints.

Characteristics of an oral and maxillofacial radiology department. Report of the ad hoc Department Characteristics Committee of the American Academy of Oral and Maxillofacial Radiology.

Oral and maxillofacial radiology is a dynamic and multifaceted discipline that plays a critical role in patient care, the education of general dentists and dental specialists, and the academic health of the dental school. Diagnostic and treatment advances in temporomandibular joint disorders (TMD), implants trauma and orthognathic surgery, and craniofacial abnormalities depend heavily on conventional and advanced imaging techniques. Oral and maxillofacial radiology contributes to the education of pre- and post-doctoral dental students with respect to biomedical and clinical knowledge, cognitive and psychomotor skills, and the professional and ethical values necessary to properly prescribe, obtain, and interpret radiographs. The development of an active and successful oral and maxillofacial radiology department, division, or section requires the committment of institutional resources. This document may serve as a guide to dental schools committed to excellence in oral and maxillofacial radiology.

Model for universal digital data format (UDDF) for medical applications

Medicine employs a wide variety of digital data in various formats for clinical and research activities. To make medical data available for all users and equipment, it must be stored in a general format that is understandable by all end users. Also data must be structured so that it can be retrieved, manipulated, and stored efficiently. In this article, we propose a paradigm for representation of digital data such that it encompasses various modes of medical data without imposing demanding compliance requirements. Also the distributed nature of the proposed data format allows efficient data storage/transmission through use of a hierarchical data servers. Such a distributed data format provides not only a universal and uniform means of data storage/communication but also a valuable resource for medical research and public health planning.
