A comparative, double-blind, observant, prospective and longitudinal study was performed over 27 patients treated at the maxillofacial surgery unit of the "Adolfo López Mateos" General Hospital, ISSSTE, for the purpose of evaluating the efficacy and tolerability of benzydamine oral spray in post-extraction inflammation. Patients of either sex and assorted ages were selected, with a prerequisite of no current pathology or previous history of hipersensibility. They were divided in two groups, the first one receiving a placebo, and 1.5% oral benzydamine spray applied to the second group. Each patient was instructed to apply the medication six times per day (with four sprays per application) for five days, and clinically evaluated before the study and after two and after five days of treatment. Female patients were predominant, and ages averaged 30.9 years in the benzydamine group and 28.4 years in the lot receiving placebo. Clinical and laboratory evaluations were performed after treatment, with superior results as to clinical course observed in the group treated with benzydamine, as compared to the placebo lot. Usefulness of benzydamine spray in the postop treatment of dental trauma (i.e., extraction of third molars), as well is its antiseptic and analgesic properties, were objectively verified in the patients.

Caries prevention with lactic bacteria. (Final results of a dental caries clinical trial using heat killed lactic bacteria [streptococci and lactobacilli] orally.) The results of a dental caries clinical trial in 245 seven-year-old children are reported. Chewable tablets of two different types were prepared: A) Containing pyridoxine (Vit. B6) and heat killed lactic bacteria. B) Placebo tablets with pyridoxine only. They were randomly given once a week for 16 weeks to experimental and control groups respectively. Four evaluation surveys were conducted during 24 months of follow up, using the "Decay, Missing, Filled, Surfaces" index (DMFS) for the clinical evaluation of the permanent teeth. A consistent reduction in the incidence of dental caries in the experimental group was observed in all 4 surveys. After 2 years of follow up a 42% reduction in the incidence rate of dental caries was observed in the experimental group compared to the control group. Summary tables and discussion of the clinical evaluation surveys are given. The potential use of these clinical findings as support for a future dental caries vaccine evaluation project is proposed.

Results of 235 surveys applied to odontologists performing root canal treatments to ascertain their general knowledge about AIDS. Special emphasis is made on preventive measures they take in their daily practice during handling of the patient, instruments and materials. The most outstanding characteristics of the disease are mentioned and some recommendations set forth for an adequate and safe treatment of the patient at the dentist's office.

The collegiate and university realms--which include lectures, students, clinical and scientific sessions--is open to growth. Furthermore, it has opened gates for new currents of thought and planted hopes for the growth and development of professors who, apart from mastering their specialty, may be familiar with didactics and directly or indirectly engage in full-time research, so that their lecturing and promotions may partially depend on the number and quality of their published works, preferably on scientific research.

A modality of elastomeric chain, Power Chain II (Ormco Co) was studied in vitro in order to observe the behavior of the force it exerts under constant elongation. Eight groups of ten samples each of the elastomeric material were placed at two different distances, 25 and 35 mm, and then proceeded to measure their magnitude at different time intervals (initial force, after 24 hours, a week and a month) under four varying conditions: cut in three and four links, pre-elongated and not pre-elongated. All specimens were immersed in saline water at a constant 37 degrees C (98.6 degrees F). Relaxation of the force observed after 24 hours was, for all groups, 52.85%, similar to that found in other studies. Although decrease of residual force was lower in the pre-elongated groups, larger residual magnitude was observed in the non pre-elongated groups.

Presents the application of an instruction package and, through it has been evaluated the efficacy of a health training program for children. By way of the use of this program on the elementary school, we detect the benefit to achieve with it, been compare with a control group, this comparison shows the health education efficacy on the oral prevention. Finally, some recommendations are made for the application of this program.

The treatment of patients with dentofacial deformities which include excessive exposure of frontal upper teeth and upper alveolar gum at resting and/or dynamic position of the lips, is a frequent challenge to odontologists, orthodontists, prosthesists and maxillofacial surgeons. This article introduces a joint orthodontic-surgical approach for the functional and esthetic correction of this deformity. Attained results are illustrated by two representative case histories.
