Two cases of herpetic intraoral infection, in inmunodepressed patients, are presented. We emphasize its diagnosis and therapeutical aspects. A bibliographic review is done.

Human teeth were filled with two posterior resins, Heliomolar and P-50, using Gluma as dentin adhesive. After this the teeth were extracted and the author studied the microleakage. The composite filling of the cavities was done following two techniques, one by layers and other with the bulk technique. The teeth were kept in saline solution at 37 degrees C and after 30 days the teeth were studied. The Heliomolar composite was able to avoid the microleakage in almost 100% of the samples independently of the inserting technique used. The P-50 composite was not able to avoid the microleakage unless in a very small number of teeth and this happened only when the layer technique was used. The difference between both is due to the greater amount of organic component in the microfilled resins producing thus a greater higroscopic expansion.
In recent years, considerable interest has been generated in the role of bacteria in causing periapical pathogenesis. This article reviews and correlates clinical and laboratory research bearing on this important topic. Bacteria in dental root canals play a decisive role in the development of periapical lesions and some of them have the ability to establish themselves in periapical tissue. Multiple mechanisms are involved: they include also immunological responses.
The authors describe in review the alveolar absorption according to bone physiology, and the absorption prevention using hydroxylapatite. Finally it is pointed the good preliminary results in a 30 patients study during 8 months using hydroxylapatite (OSTEOPATITE) and plaster particles in alveolar absorption prevention.
This work describes modifications of clinical methodology for the use of composite resins (changes in the isolation of the operating field, in the preparation of the cavities to be occluded and in the way the resin is applied), and relates them to studies of the fine structure of dental enamel and of the adverse side-effects of resins.
The author makes a review of Non Hodgkin's Lymphoma and Oral Presentations, and includes a case report of the Oral and Maxilo-Facial Surgery of the Snt. António's Hospital--Porto.
The incidence of dry mouth complaint on enquiry was found to be 3.3% on average in a retrospective study of the records of 2500 patients who attended the Cork Dental Hospital. The lowest incidence (1.20--2.66%) was in the youngest age group studied (6--20) years. The incidence increased with age and was substantially higher, reaching 20% in elderly females. In all age groups there was a higher incidence in females. The results are compared with two other studies carried out in Scotland.
