Clinic exams of pulpal sensibility and periodontal conditions were made, as well as periapical radiographies of the transplanted teeth for pulpal and periodontal analysis. From the results was verified that: 1) There was, during the period, decrease of pulpal answers in the sensibility tests of transplanted teeth with incomplete rhizogenesis. There was also greater presence of pulpal calcifications and increase of radiopacity of light in radicular roots comparing to non-transplanted homologous teeth; 2) The occurrence of pulpal necrosis was, in great majority, related to the degree of radicular development. Radiographic signs of pulpal necrosis were more often in transplanted teeth with complete rhizogenesis; 3) Retraction and gingival bleeding were eventually found and related to bad mouth hygiene, not happening installation of periodontal pocket verified by sounding, nor pathological alterations of dental mobility; 4) The constatation of external radicular resorptions did not compromise the transplantation 's success; 5) Periapical radiographic images indicating periapicopathy were linked to pulpal necrosis. Those permitted us conclude that: 1) Reintegration of the transplanted tooth in its new site was considered a success in all specimens; 2) Transplanted teeth in incomplete rhizogenesis stages presented better results of pulpal reparation than transplanted teeth with complete rhizogenesis; 3) Dental transplantation is a therapeutic able to rehabilitate physiologic and esthetically traumatized patients with superior incisive loss; 4) The success of this therapeutic depends on observation of various factors, including a severe surgical contral.

The cytopathological results of the FNAB were compared with the histopathological results which, statistically showed indexes of precision of 95,66%, excluding the samples considered insatisfactory for diagnosis (7,52%). We have found 15 false-negatives results and just one false-positive (88,46% of sensitivity and 99,58% of specificity indexes). So, this thecnic of aspirative biopsy was satisfactory in early and redirectionable diagnosis in neoplasic and noneoplasic lesions, besides its feasible facilities, high precision, low costs and almost free of complications.

Twenty two patients, ranging in age from 22 to 62, were given through clinical and roentgenographic examinations. The sample include 30 single rooted teeth with no carie, abrasion, attrition, erosion or restoration. Radiographically, ali teeth showed support bone destruction to the apex. Periodontal evaluation included measurement of pocket depth and the distance between the cementum - enamel junction from the gingival margim of each teeth. Adding these two values gave us the attachment loss. This data was compared to the mean length of the dental roots, and · often over passed it, confirming the destruction of the support tissues. Pulp vitality was evaluated by thermal tests and test cavity. After the teeth had been extracted the crowns were separated from the roots at the cementum-enamel junction. The samples was fixed in 1 O % formalin solution, decalcified, embebbed in parafin, cut, stained with Hematoxylin - Eosin and Gomore's trichome, and examined under the microscope. Within the limites of this investigation, we can conclude that: 1) ln 100 % of the cases, the coronal pulp showed to be fo soft connective tissue; 2) ln 23 % of the cases, fibroses was present at the coronal 2/3 of the radicular pulp and in 16,6 % at the apical; 3) ln 76,6 % od the cases, fibroses associated with difuse calcification was present at the whole extention of the radicular pulp; 4) ln 16,6 % of the cases, fibroses associated with chronic inflamatory infiltration was observed at the apical 1/3 of the radicular pulp; 5) The result of the pulp vitality tests were positive for ali teeth used in this investigation.

The study was done at UNIGRANRIO'S babies clinics, Duque de Caxias, RJ - Brazil. 333 children they were selected the both sexes (49.5% male and 50.5% female), 312 from the group of children born with normal weight and 19 born with low birth weight. The incidence of low birth weight found as a result of studying the samples was 5.7% in relation to children born with normal weight. The average age of the children's mothers born with normal weight was 27% whereas in the group of low birth weight was 26.3%. 70.6% of the children born with low birth weight were had a normal birth, whereas in the group of the normal weight it was 63%. Furthermore, there was no meaningful difference found with regard to the actual age of the primary teeth, in spite of the precocity of the eruption in all male children. About the weight at birth, it was not observed significant difference statistically, in relation to the average of the eruption of primary teeth, in spite of verifying that the eruption of primary teeth in children from the group of low birth weight was late, in comparison to the children with normal weight.
