Geriatric dentistry.

The over-55 age group--the most rapidly expanding portion of the population--until recently has been the least understood patient group treated in the dental office. During the last decade, the special dental care needs of geriatric patients have been the subject of many research efforts. Understanding the interactions between the systemic health problems and disease trends of the elderly and their oral health has helped the dental profession gain greater insight into treatment strategies tailored to their needs. Evaluation of the patient's systemic health is critical to identifying complicating factors that can interfere with or be exacerbated by dental treatment. Understanding these disease trends can also sensitize the dentist to the presence of previously undiagnosed oral signs of systemic disease. In addition to the patient's systemic health, oral and dental status and individual expectations and desires must be considered when developing a treatment plan. In considering all of these variables, optimal treatment can be rendered to restore function and aesthetics in a manner that will help maintain and improve the patient's health and psychologic well-being.

The role of the prosthodontist in the correction of swallowing disorders.

The contributions of the prosthodontist to the swallowing rehabilitation treatment team are described. The aims and goals of prosthetic intervention are highlighted. An account is given of the various site-specific prostheses that can be fabricated to enhance swallowing performance.

Effect of a maxillary glossectomy prosthesis on articulation and swallowing.

Swallowing was found to be substantially improved with the prosthesis. Less aspiration, less time necessary to complete the swallow, and greater variation in food consistency tolerated were all positive results of the prosthesis. In addition, videofluoroscopic studies of tongue movements during speech revealed that tip-alveolar /t-d/ and back-velar /k-g/ productions were more normal with the prosthesis. With the prosthesis, the understandibility of /t/ and /d/ was improved 20% and that of /k/ and /g/, 33%. It is clear that compromises must be effected in prosthesis design to facilitate improvement in both speech and swallowing. A large prosthetic mass in the oral cavity can also negatively change speech resonance. These issues are being investigated, as are acoustic and perceptual studies of speech articulation. Future research should address whether a combination of maxillary and mandibular prostheses would result in better speech and swallowing function. A mandibular prosthesis could replace missing teeth and alveolar contour that might influence speech and swallowing. A mandibular prosthesis might also allow construction of a smaller maxillary glossectomy prosthesis to interact with the mandibular prosthesis.

Dental considerations in management of head and neck cancer.

The successful management of patients with squamous cell cancer of the aerodigestive tract requires a multispecialty team. Cooperation among these individuals will ensure that the patient has the best possible chance for a favorable outcome. The role of the dentist as a member of this team is discussed.

In vitro studies of fluoridated amalgam.

Four types of fluoridated amalgam were assessed in vitro in terms of fluoride release, corrosion behaviour and compressive strength, and compared with amalgams prepared from the corresponding non-fluoridated alloys. Although corrosion susceptibility was found to be increased, steady release of the fluoride ion was demonstrated over a 16-week period, indicating that fluoridated amalgams might be prophylactically employed in clinical dentistry as a means of overcoming the problem of secondary caries associated with amalgam restorations.

Teeth, vomiting and diet: a study of the dental characteristics of seventeen anorexia nervosa patients.

Seventeen anorexia nervosa patients were examined dentally and their dietary histories and eating habits studied. Analysis of the data confirmed earlier observations dental deterioration associated with anorexia nervosa. The deterioration included a pattern of enamel dissolution in cases of vomiting, regurgitation, and/or the consumption of large amounts of citrus fruits; and an altered caries response due to abnormal carbohydrate consumption. Despite the patient's probably insistent denial of 'anorectic' eating habits, the general practitioner should consider the existence of anorexia nervosa in the presence of such abnormal features, especially in young women. The relationship of these findings to larger populations with similar eating habits is discussed.
