Purpose: To evaluate the number of patients with dental implants who present to a dental school clinic for screening and to report the prevalence of peri-implant bone level change detected on digital panoramic radiographs of those subjects., Materials and Methods: Patient screening files for 9,422 patients over a 2-year period were examined to see how many patients presented with dental implants. Those patients with at least one implant were further evaluated by measuring the bone level on the mesial and distal sides of the implant using the screening radiograph., Results: A total of 187 patients (2%) had at least one implant. In regard to implants, 423 were examined and 146 (33%) had no detectable bone loss defined as bone level below the top of the implant. When thresholds of bone loss were evaluated, 109 implants (25%) had ≥ 2 mm of bone loss on either the mesial or distal sides or both. The median bone loss was 1.74 mm for the 277 implants with detectable bone loss and 2.97 mm for the 109 implants that had ≥ 2 mm bone loss. Interestingly, patients who were ≥ 70 years of age had significantly (P = .03) more bone loss in the mandible compared with the maxilla, while patients who were 60 to 69 years of age had significantly greater loss in the maxilla., Conclusion: These data reveal that for patients presenting to the dental school for a screening over a 2-year period, 1.98% had one or more dental implants. Furthermore, those patients with implants had a minimum amount of bone loss as measured from the top of the implant.

As society transitions deeper into the Information Age, Information Technology has become a critical tool that supports all facets of the global economy. The Internet, via the World-Wide Web (WWW), has become a major component of business operations for corporate and educational organizational entities. An estimated 10,000 or more health-related websites are providing information for both consumers and healthcare professionals. In addition to private and state-supported institutions being present on the Internet, the federal government has moved rapidly toward disseminating information electronically, with significant utilization of the WWW as the technological vehicle. All branches of the US Government and federal-related agencies are now represented on the Internet in an effort to deliver content to their end users, primarily the public. The intent of this article is to complement the previous publication, "Internet Resources for Dentistry: Utilization of the Internet to Support Professional Growth, Decision Making, and Patient Care," by presenting dental healthcare professionals with information on additional governmental and medical "Internet" sites. In addition, healthcare professionals must arm themselves with more than just access itself, but also the ability to critically judge the quality of information retrieved from the WWW.

The use of computers as an information resource in dentistry has grown dramatically over the past ten years. Fueled by the availability of more powerful computers, societal acceptance of computer-based resources, and the development of the Internet, millions of documents now provide a tremendously important repository of information for healthcare providers. Those involved in delivery of dental care need to know how to access and use this information for their professional development and to support clinically related activities. This paper presents issues related to the use of the Internet. It also provides information on the use of search engines to find resources (websites) on the Internet and descriptions of some available resources of interest to those involved in oral healthcare.

Objective: A patient's medical condition can affect the delivery of dental care. Medical consultation is indicated for dental patients whose medical history is uncertain or when physical assessment may indicate an untreated medical problem. The aims of this study were to evaluate the use of medical consultation and determine how it affects dental treatment plans in a predoctoral dental clinic program., Study Design: Reviews of 147 medical consultation requests were performed., Results: The main reasons for medical consultations were cardiovascular assessment (51.5%) and diabetic status determination (12.6%). In the cardiovascular assessment category, hypertension (48.1%) and heart murmur (17.9%) were primary concerns. Main dental concerns were the need for preoperative antibiotic prophylaxis (33.3%) and the use of vasoconstrictors (20.4%). Overall, 32.1% of medical consultations resulted in an alteration in dental treatment plans. As a result of medical consultations, 8% commenced their medical management., Conclusions: These results indicated that medical consultations could reduce the medical risk associated with dental procedures and unnecessary antibiotic prophylaxis. Therefore for many dental patients, good communication between dentists and physicians is essential for adequate care.

The authors surveyed 5,002 dental outpatients to determine the prevalence and patterns of drug use. They found that drug use increased significantly with age and that a significant number of patients took medications that had potential for adverse dental effects. Thus, dentists should be aware of patient medications and the effects those drugs have on dental treatment.

Human cells in early passage cultures of benign oral tumors, normal oral tissues, normal lung tissues and, especially, in long-term established oral carcinoma cultures were highly susceptible to infection by human adenovirus types 5, 21, and 31. In contrast, replication of each adenovirus type was markedly limited in inoculated cells of newly-established oral squamous cell carcinoma cultures.

Levels of immunoglobulin class-specific antibodies as determined by solid phase radioimmunoassays to herpes simplex virus type 1 (HSV-1), human adenovirus types 5, 21, and 31 and to Candida albicans in sera from untreated healthy dental patients were not significantly different from levels of these antibodies in sera from untreated dental patients with benign oral tumors, oral carcinoma, or periodontal disease. These results show that higher levels of immunoglobulin class-specific antibodies to HSV-1, the three adenoviruses, or Candida albicans are not a consistent finding in sera from patients with oral cancer when comparisons are made with healthy patients and patients with other oral diseases.
