The investigation aim is determining the histological changes which appear in the femur and the jaw of the albino rats offspring during the gestation and the nursing, until the 28 days of age having different riboflavin concentrations in the diet. It was conformed four groups of Holtzman albinos rats with reproductions capacity, according to the demand of riboflavin: Group A (100% of B), Group B (50% of B), Group C (25% of B) and Group D (0% of B). The rats offspring of each group were extracted and sacrifidied at the 0, 7,14, 21 and 28 days from the birth. Then they were submitted a histological studying with Eosin Hematoxylin and Masson Stains. The deficiency or total lack of B2 produced alterations in the of offspring growth and development. The obtained results showed: small light and diminution of the corporal weight, and microscopically reveals: for total lack of Riboflavin in the ...

Esta investigación experimental tuvo como objetivo determinar los cambios histomorfológicos que ocurren en el tejido dentoalveolar de la mandíbula de una progenie de ratas albinas sometidas a dietas con diferentes concentraciones de Riboflavina (B2) e iguales concentraciones del resto de nutrientes, durante la gestación y la lactancia hasta los 28 días de edad. La literatura no reporta estudios que aborden los efectos que se dan en el tejido dentoalveolar por ausencia o deficiencia de B2 desde el punto de vista histológico, y en especial cómo influye en el número de la población celular presente en la unidad dentoalveolar. Se conformaron 4 grupos de ratas albinas (raza Holtzman) con capacidad de reproducción, según el requerimiento de Riboflavina: Grupo A, grupo control, con 100% de B2; Grupo B, con 50% de B2; Grupo C, con 25% de B2 y Grupo D, con 0% de B2. Las crías de las r...

The inclusion of the fascicle higher external pterygoid muscle (Lateral Pterigoid) disk articulate occurs from the middle third of the central region and contributes to the displacement of the disc and its alteration help discal displacement. On the insertion, there are differences of opinion; some consider that only a small portion of fiber is inserted into the anterior capsule and thus directly and indirectly to the disk; other researchers point out that it is directly inserted the disk and the condyle or only on the anterior edge of the capsule and the disc. The objective of the study was a histological analysis of the insertion of this muscle to differentiate the type of fibres that reach the disk articulate (proportion of collagen fibers and muscle fibers) and determine the type of union between the muscle and the disc articulate. The sample of this study of transverse and explorato...

The main objective of this study was to determine the profile of oral health and disease of the elderly adults of urban Lima, taking into account the prevalence of dental caries, periodontal disease, oral mucosa injuries and treatment needs. Descriptive and transversal study was using over 120 elderly adults (over 60 years old), living in Lima center and district. Data collection was performed by the method of clinical observation and interview using rates and procedures of the WHO. The results obtained were: average age 71 years, high prevalence of the female gender (70%) and secondary education, presence of hypertension with 33 % and diabetes mellitus with 10.8%, the mucosal disorders in 10.8 %, with ulceration type localized on the palate and alveolar ridges. Also was observed presence of calculi and periodontal bleeding in 52% of the population. The study subjects requiring prophylax...
