The parendodontic surgery intends to the resolution of accidental or pathological condition that can't be recoverable by usual endodontic treatment. In this case, the authors present a clinical case where a apical curettage and apicectomy were done in a mandibular right third molar, to show the account of this procedure yet in the actual context.

The authors present a clinical case of adhesive prosthesis on posterior teeth, where it is proposed an alternative technique based upon the retentive principles of removable parcial prosthesis, diminishing the elimination of enamel.

The purpose of this study was to verify the effect of hypothalamic median eminence lesion on healing process in fracture of anterior portion of zygomatic arch, in rats, by histologic evaluation. The animals were killed in number of 5 for each periods at 6, 12, 24 and 36 days post-lesion. Our results showed morphologic changes and tinctorial in all considered periods, with more evidence at 12 and 24 days post-fracture and evidents signals of hipomineralization. This disfunction appeared only after a mean period of 12 days post-lesion.

The authors emphasize the some functional characteristics of the Temporomandibular join, TMJ, and were made comparative study of the auscultatory and sphymografic techniques to TMJ examination. The findings shown that the auscultatory technique furnished important dates to preliminary diagnosis of the TMJ disfunction.

One of the problems of difficult solution in clinic are the tissue lost from periodontic surgery procedures. The purpose of this survey is to help find the solution of this problem, and we show a case where the patient has great interdental tissue lost after surgery and was solucionated with an acrylic resin appliance. The clinic results prove the efficiency of the appliance, diminishing or having the hole esthetic and phonetic problem solucionated, besides the low-cost of its confection and also allows the patient to have a good plaque control.

With the aim of studying in the fibrous structure of the compact bone, as revealed by the split-line technique, unilateral surgical transposition of the masseter muscle from the masseteric fossa to the central area of the mandibular body below the molar teeth was performed in seven adult rabbits. Six months later the animals were killed, their mandibles were removed, cleaned and then decalcified. Split-lines were made on the lateral surface of both the control and the operated side of the mandible. Myotransposition induced alterations in the split-line patterns; they showed to be entangled and disorganized, which mean structural changes in the bone itself.

The authors studied in vitro the capacity of FORP-USP cavity varnishes, COPALAINE (Prodonto), COPALITE (H. J. Bosworth Co.), CAVITINE (SS WHITE) and UNIVERSAL (SS WHITE) to promote impermeabilization. The tests were done by the use of filter paper and the impermeabilization was measured by the Rhodamine B stain infiltration. The FORP-USP cavity varnishes Copalaine and Copalite were more effective in promoting impermeabilization.

Daily administration of 150 IU vitamin A/gram of body weight in mice, during 10 days, led the authors to observe: submandibular glands showed acini of slightly reduced size, with lower cells whose contours were not always sharp and containing smaller number of cytoplasmic granules. The nuclei of the acinar cells were reduced in volume. The granulose ducts were similar to those of the controls in size but showed signs of degeneration as well as cell nuclei of reduced volume. The striated ducts were smaller than those of the controls, while the excretory ducts were dilated, with lower cells and nuclei of reduced volume. General examination showed that the hypervitaminotic animals had more abundant connective stroma than the controls. The glandular structures were studied morphometrically and estereologically.

The solutions preference and the body mass variations during rehydration was analyzed in dehydrated rats. The dehydration was provoked by hydroprivation during 72 hours. The results shows a sodium chloride specific appetite, mainly in the initial part of the rehydration, and hypo, and isotonic sodium chloride solutions preference. The sodium chloride, and glicose solutions treatment was better than other solution in the body mass recovery.
