Enamel dissolution and fluoride uptake from sugar solutions.

Solubility studies and fluoride uptake by enamel powder in xylitol-buffered solutions versus sucrose- and glucose-buffered solutions were carried out. The studies were done at a pH range of 4-8. The enamel solubility in the xylitol media was similar to the enamel solubility in the other sugar solutions--increasing with a decreasing pH. The solubility of enamel in the buffered sugar solutions was significantly lower as compared to the solubility in the sugar-free buffered solutions--up to the pH of 6. At the pH values of 7 and 8 the amounts of solubility were similar for the experimental and control solutions. No significant differences were found in the fluoride uptake by the enamel powder from the fluoride-containing sugar solutions at the pH values of 6 and 7.5 respectively. The results point to the conclusion that the xylitol does not differ from sucrose and glucose in its effect on enamel powder solubility and the uptake of fluoride ions by enamel.

Lymphosarcoma of the mandible associated with macroglobulinemia of Waldenström.

Waldenström macroglobulinemia is a rare progressive immunoproliferative disorder involving lymphocytes and occasionally plasma cells. Unlike the multiple myeloma, this disease has minimal osseous lesions. Lesions in the jaws are very rare. This paper presents a case of lymphosarcoma in the mandible in a 68-year-old woman, who was diagnosed as suffering from Waldenström macroglobulinemia. The possibility of immunosuppression by Leukeran as an aetiologic factor causing the bone lesions is suggested.

Overdentures for patients who are chronically ill: a 4-year follow-up.

In 12 chronically ill patients, 14 overdentures were inserted. The status of the retained teeth and the denture-supporting structures was evaluated annually for up to 4 years. The limitations and implications of this therapy as related to specific chronic diseases, medications, and patient behavior are emphasized. Based on short- and long-term follow-up, recommendations for the applicability of overdentures in systemically ill patients are offered.

Perioperative hemodynamic changes in ischemic heart disease patients undergoing dental treatment.

Twenty patients with stable ischemic heart disease in functional capacity Class II-IV underwent dental treatment. Scaling was performed in seven patients without local anesthesia. In the remaining 13 patients, pain control for restoration placement was obtained by local anesthesia: in seven patients, the anesthetics contained epinephrine, while in six this drug was omitted. Heart rate, blood pressure, and electrocardiograph were continuously monitored during the dental session. All patients had elevated systolic blood pressure and rate pressure product during treatment. In the patients who received plain local anesthetics only, the elevation in systolic blood and rate pressures was, however, significantly lower than the ischemic threshold. Arrhythmia or ST segment depression of > or = 1 millimeter were not recorded in any of the subjects. In severely compromised ischemic heart disease patients undergoing routine dental procedures of limited chair time, plain local anesthesia seems to be the preferred analgesic modality.
