Action Community regarding health is but part of a long-term project started out back in the 1960. As far as Latin America was concerned the so-called experience did not work out; notwithstanding, it has become an Attention-Getter among the countries of the area once again. How so? Because of the Primary-Approach. Understood as an approach based on the global development of society, self-involvement lies at the cornerstone of the whole process. The health section gives full measure of the primary-approach theoretical framework and propose alternatives to get it of the ground. Professionals from the health section aim at "self-involvement" as activity performed willingly. Besides as it were, it should be supervised by experts. Nowadays the venezuelan government promotes action community claiming it will endorse the Primary-Approach on health granted the national health system bill is approved. Amid such context dentistry most meet the challenge of upcoming changes, so must fellow-dentists who, in the end, will dominate center stage. The process must narrow down to actions with will stem from its own dynamics along the way. Needless to say, these actions can not be easily foreseen, let alone do they guarantee success.

The ecological niche of oral mycoplasmas are both gingival pockets in patients suffering periodontitis (PP) and gingival sulci in individuals with healthy gingiva (HG). The mycoplasmas migrate from these anatomical sites to the saliva and to entire oral cavity. The purpose of this report was to examine whether differences exist in the incidence and concentration of mycoplasma as determined in the saliva of thirty (30) PP and fifty (50) individuals with HG. Saliva samples were obtained from both groups, with capillary tubes and cotton swabs, and used for mycoplasma isolation and quantification. The methods employed were those recommended by the Centers for Diseases Control (CDC Atlanta, Georgia). The results showed an 80% mycoplasma incidence in group PP and 50% HG, with the following concentrations: 5.0 x 10(3) to 8.0 x 10(6) Colony Forming Units/ml (CFU/ml) in PP, and 3.0 x 10(3) to 4.5 x 10(4) UFC/ml in the HG (P less than 0.001). We conclude the both mycoplasma incidence and concentration were higher in PP than in HG individuals.

A review of the more relevant clinical, radiological, histopathological and genetics aspects of Dentinogenesis imperfecta (DI) is presented, together with the description of a family with DI. The complete analysis of the affected and non-affected members showed that the defect can be classified as a DI type II with an autosomal dominant mode of inheritance with complete penetrance and variable expressivity. Also it is necessary to emphasize the importance of a multidisciplinary approach (Pedodontists, Oral Pathologists and geneticists) in the description, diagnosis and treatment of the individuals affected with DI.

In order to elaborate an attitude model of patients that come over to the School of Odontology of the Central University of Venezuela, asking for odontological treatment, from the subject's point of view about the general odontology health and his own odontology health, we have done this investigation work, where we interviewed 250 persons that came over to our service and each of them were assigned to the students, from there and on we do our suggestions and to be considered in order to assist this people.

Oral hairy leukoplakia (OHL) is a new lesion that appears specifically on the lateral borders of the tongue. It has basically been detected in immunosuppressed male homosexuals and it is associated with the later development of the acquired immunodeficiency syndrome (AIDS) or HIV infection. Epstein-Barr virus has been suggested to be the possible etiological agent. A review of the existing literature pointing out definition, clinical, histopathologic and ultrastructural features, prognostic and treatment is made. Moreover the characteristics of the individuals suffering from it are equally studied. The role of the dentist at detecting the lesion, as well as the importance of its definitive diagnostic are emphasized, in virtue of the effects that may have a bearing on patients.

In this study, the microbiological composition of the dental plaque in 12 male Sprague-Dawley rats was determined. Analysis using the light microscope showed the presence of nine colonies which suggested the presence of cocci, (6) diplococci (1) and rods. (2) Five of the bacteria were Gram positive and three were Gram negative. The morphological characteristic suggested the presence of Actinomyces in the case of Gram positive rods; Fusobacterium in the case of Gram negative rods; Neisseria and Veillonella in the of Gram negative cocci and Streptococci for the rest of the colonies. The biochemical characterization of the bacteria suggested the absence of Streptococcus mutans in the dental plaque of this animals.
