Subperiosteal surgical Vitallium implants have been set in the mandible of patients with loss of height of the osseous ridge and difficulty in the use of prostheses obtaining very good clinical and radiographical results.

The prevalence of the herpes simplex virus infection was investigated in a chilean female population. During 1981 and 1985 a number of 1,003 women were analyzed through serological methods. A 29.1% of the group referred past history of oral herpes and 59.4% of these presented 1 to 2 recurrent episodes a year. The high prevalence of this infection in our population is shown when detecting that a 91.4% of the female population had antiherpes simplex antibodies and the titer of this antibodies were in direct correlation to the antecent of recurrent clinical herpes and to the frequency of these episodes.
A poorly differentiated squamous cell carcinoma arising in the left maxilla of a seventy year-old female is reported in the present paper. The patient was seeking treatment for a maintained nose bleeding which appeared several days before. In addition to the report of the clinical case, the authors rewied the main features of the disease, emphasizing the low frequency of the condition, as compared to other neoplasic involvement arising in the head and neck. Due to the advanced stage of the case herewith reported, the patient underwent no treatment.
The decreasing of vertical dimension, specially in extremely cases (more than three clinical standard deviations) is a border problem between orthopedics, orthodontics, prosthetics and surgery. The authors reviewed the treatments possibilities proposed by the different specialties.
Based on results of a diagnostic test which measured the knowledge that University of Chile students of 5 different health careers have a food and nutrition (1982), the nutrition program of the school of Dentistry was modified from a traditional system of education (formal classes) to a participative methodology in 1984, a didactic material on nutritional recommendations. An increased level of knowledge as well as motivation was observed in those graduating in 1984, particularly the area of nutritional recommendation and diet, to which the students spent more extra time. We can conclude that the educational methodology that stresses participation and is centered around one person is very effective to teach nutrition in the school of Dentistry.
