Abstract: the purpose of this study was to assess the current knowledge and recommendations of obstetricians and dentists as to the dental care to pregnant patients in the cities of londrina/pr and bauru/sp, brazil. questionnaires were distributed to professionals of both cities, arguing on the following issues: oral health during pregnancy; contact between prenatal care and dental care providers; prenatal fluoride supplementation; selection of therapeutic agents for local anesthesia, pain control and treatment of infection; and dental procedures that can be performed during each trimester. data were analyzed by frequency of responses and statistical analyses were carried out using x2 (type of workplace/service) and t test (time since graduation), significant if p<0.05. seventy-nine obstetricians and 37 dentists responded the questionnaires. most physicians referred the patient to dental care only when a source of dental problem was mentioned, limiting the adoption of a preventive approach. forty-three percent of dentists and 34% of obstetricians did not know the potential contribution of periodontal infection as a risk factor for preterm low birth-weight babies. there was divergence from scientific literature as to the recommendation of local anesthetics (dentists and obstetricians), prenatal fluoride supplementation (obstetricians) and dental radiographs (dentists). the findings of this survey with dentists and obstetricians showed that dental management during pregnancy still presents some deviations from scientific literature recommendations, indicating the need to update these health care professionals in order to establish guidelines for prenatal dental care.

Abstract: Las dolencias producidas por la caries dental y otras afecciones bucales son múltiples, lo que hace al paciente acudir a los servicios de urgencia. El propósito de este trabajo fue evaluar la relación del estreptococo mutans y lactobacilo y algunas variables demográficas con la caries dental en ni os, pertenecientes a cinco consultorios del área de Contreras, del municipio de Matanzas, para lo cual se realizó un estudio analítico del tipo de casos y controles. La muestra se obtuvo mediante un dise o muestral probabilístico estratificado polietápico y quedó conformada por 900 ni os (300 casos y 600 controles) de 6 a 12 a os de edad. Hubo un predominio de ni os en las edades de 6 a 8 a os, tanto en los casos como en el grupo control, y no se observaron diferencias significativas entre ambos grupos. El sexo femenino prevaleció en los controles, y el masculino, en los casos. Los ni os pertenecientes al grupo de casos, tenían un alto grado de infección por estreptococo mutans y lactobacilos, y se demostró asociación positiva de la caries dental con estas variables. Se dise ó una estrategia educativa para evaluar y elevar el nivel de información que sobre esta enfermedad tenían los ni os objetosde estudio. The disorders produced by dental caries and other oral affections are multiple, making the patient assist to the urgency service. The purpose of this work was evaluating the relations among the sreptococcus mutans and lactobacillus and some demographic variables with dental caries in children, registered in five medical consulting rooms of Contreras area, municipality and province of Matanzas, for which we carried out an analytic study of the cases kind and controls. The sample was obtained by means of a polistaged, stratified, probabilistic design, and was formed by 900 6-12 years-old children (300 cases and 600 controls). There was a predominance of 6- 8 years-old children both in the cases group and in the control group, and there were not significant differences between the groups. There was prevalence of female children in controls and of male in cases. Children from the cases group had a high infection level by streptococcus mutans and lactobacillus, and there was stated a positive association of dental caries with these variables. We designed an educative strategy to evaluate and increase the information level studied children had on this disease.

Abstract: Background: Lengthening the maxillary dental arch as a treatment approach for patientswith maxillary deficiency and dental crowding is seldom reported. The purposeof this study was to assess dental and skeletal changes in the maxilla inthe correction of maxillary deficiency associated with a retruded maxillaryarch using a surgically assisted rapid maxillary anterior-posterior expansionappliance.Methods: Predistraction and postraction lateral cephalometric and periapical radiographsand maxillary dental casts of six young adolescents (four boys, twogirls, mean age 11 years, 2 months) were examined. These patients receiveda maxillary anterior segmental osteotomy and distraction osteogenesis withan anteroposteriorly oriented Hyrax expansion appliance based on the biologicalprinciples of bone distraction.Results: The retruded dental arch and dental crowding were successfully corrected.Significant forward movement of the point anterior nasal spine, point A, centralincisors and first premolars was noted. The maxillary dental arch depthincreased an average of 4.2 mm while the arch width remained unchanged.In total, 11.5 mm of dental space was created in the maxillary arch whichwas sufficient to resolve dental crowding. New bone formation along the distractionsite was observed three months after distraction.Conclusions: The use of maxillary anterior segmental osteotomy combined with a Hyraxexpansion distraction appliance was effective in arch lengthening and creationof dental space. An overcorrection in this interdental distraction osteogenesiscould be a good treatment option for children with maxillary deficiencycombined with crowded maxillary dentition.

Abstract: La caries dental es una enfermedad de alta prevalencia, que provoca episodios desagradables a quienes la padecen. Con el objetivo de caracterizar el comportamiento epidemiológico de las urgencias por caries dental se realizó un estudio descriptivo, transversal, en el Policlínico Universitario 7 de Diciembre, de Jagüey Grande, provincia Matanzas, comprendido en el período de septiembre a noviembre de 2007. El universo lo constituyeron 1 260 pacientes cuyo motivo de urgencia fue la caries dental. Las variables estudiadas fueron edad, sexo, nivel de escolaridad, área de procedencia y motivo de consulta. La información fue obtenida de las historias clínicas. Se comprobó que la caries dental constituye la primera causa que demanda atención de urgencia en el servicio estomatológico, que los pacientes de 20-34 a os de edad, y del sexo femenino son los que acuden con mayor frecuencia a la consulta de urgencia por caries dental, en su mayoría de nivel medio superior y de procedencia rural. The dental caries is a high prevalence disease, causing unpleasant episodes to all the people suffering them. With the objective of characterizing the epidemiologic behavior of the dental caries urgencies, a descriptive transversal study was carried out at the Teaching Policlinic 7 de Diciembre, Jaguey Grande, province of Matanzas, in the period from September to November 2007. The universe was formed by 1 420 patients assisting the urgency service and the sample by 1 260 whose urgencies were dental caries. The studied variables were age, genre, scholarship, area of precedence and consultation motive. The information was obtained from the clinical records. It was proved that the dental caries is the first cause demanding urgency care in the stomatologic service, that the patient assisting more frequently to the urgency services for dental caries are the female one who are 20-34 years old, most of them with a senior high school scholarship and living in rural areas.

Abstract: Mariliasuchus amarali Carvalho & Bertini, 1999 , a Mesoeucrocodylia from the Adamantina Formation (Bauru Basin, Upper Cretaceous) shows some adaptative features to terrestrial environments: short and high skull, lateral orbits, frontal external nares and reduction of the dental formula with specialization of the tooth crown morphology in incisiform, caniniform and molariform teeth. It has been included in the infraorder Notosuchia Gasparini, 1971. Three specimens of Mariliasuchus amarali, found near the municipality of Marília, S o Paulo State were analysed. One of them, holotype of Mariliasuchus amarali (UFRJ DG 50-R), is a juvenile crocodylifom whereas the other two (UFRJ DG 105-R and UFRJ DG 106-R) are adult animals. These fossils allowed an analysis of the ontogenetic development patterns of this species. It was performed a comparison betweeen the mandibular, laterotemporal and supratemporal fenestrae and the skull sculpturing in the three specimens. The results show that Mariliasuchus acquire in the course of its ontogeny a thicker and stronger skull. The caudal migration of the laterotemporal fenestra and the size increase of the supratemporal fenestra probably indicate a wider use or strength of the adductor muscles during seizing and food processing.

Abstract: Bivalves mollusks fossils of Bauru Group (Late Cretaceous, Bauru Basin) deposited in scientific collections and collected in outcrops from Monte Alto municipality, S o Paulo, are analyzed in their taphonomy. The preservation of recrystallized individual in carbonatic matrix indicates substrate remobilization by unidirectional energetic event in fluvial discharge. The specimens with conjugated valves possess internal sediment similar to the external indicating low exposition to Taphonomical Active Zone, suggesting a bioclastic low time-averaging. The truncate and fragmented posterior portion of specimens from scientific collections is probably related to the incapacity of the taxa to reburrowing the substrate in drowning periods. Both taphonomic patterns corroborate evidences of a fluvial paleoenvironment in the Bauru Group.
