RESUMO
A statistical study of 1289 biopsies of children 0-15 years old, received at the Pathology Department, Dental Faculty, Buenos Aires University is presented. This number, represents 6.8
of the 18,966 biopsies received from 1960 to 1985. The histologic diagnosis were grouped into the following categories: 1) cysts, 2) tumour-like lesions, 3) inflammatory lesions, 4) neoplasms, 5) neck and head non-oral lesions, 6) dental anomalies and pulp diseases, 7) unclassified diagnosis. Cysts were the most frequent lesion (25.4
were localized in the jaws and 25
) were less frequent than the soft tissue tumour-like lesions (79.9
). Inflammatory lesions and neoplasms in children, account for 15.7
of the lesions respectively. Eighty four percent of the neoplasms were benign and 16
of all the neoplasms studied. These results indicate the need to be constantly aware of the possible presence of these clinical and radiographic lesions to allow for early diagnosis and adequate treatment.
RESUMO
In this study the relative frequency of oral lesions was evaluated in a group of 526 patients, 55 years old or elder. Clinical and pathological data were obtained from 244 patients who attended to a clinic of Medical and Social Assistance Program (PAMI) ad from 282 cases registered in the files of the Surgical Pathology Laboratory F.O.U.B.A. (LAP) since 1984 to 1986. The mean age of the groups was 63 years old. The most frequency lesions were the pseudotumors (44.6
) in LAP and (17.2
) in PAMI; premalignant lesions were (20.5
) in LAP, while in PAMI (2.4
). The cysts in LAP found (15.6
) in PAMI were (2.4
). The groups of PAMI showed (90
) of Candidiasis. Traumatic ulcer (30.7
) and afthae (28.8
) the traumatic ulcer. The malignant tumors the most frequency was carcinoma espinocelular (8.16
) LAP and (6.56
) PAMI. It was remarkable that stomatodine as represented in PAMI (72.2
) and Candidiasis were (90
of the specific inflammations. Results suggest that oral mobility in elderly patients correlates with the findings in this type of social assisted groups. The figures of the importance of methodical collaboration of Stomatologists and Oral Pathologists for differential diagnosis.
RESUMO
AIDS is a systemic infection that in many steps of its evolution presents various oral lesions and clinical conditions. This fact raises a problem for the dentist who are working on heterogeneous populations of healthy and infected people as well as on AIDS patients: to receive a continuous update about the disease. Apart from the risks of exposure inherent to his personal relation with HIV-infected or AIDS patients, the dentist is one of the health careworkers who must and ought recognize the oral signs of the disease when they appear in the mouth. For this reason this paper describes recent data on oral findings in AIDS: fungal, viral and bacterial infections, neoplasms and other manifestations of unknown or rare etiology. The most precocious clinical or pathological characteristics of these oral diseases suggesting HIV-infection or its results, are also stressed when described. Some doubts are possessed here about the meaning of outstanding oral AIDS lesions as [quot ]hairy leukoplakia[quot ]. On the other way diagnostic methods which can help to recognize this lesion are also commented.
RESUMO
Literature reports appeared in the last years suggested that some type of dentigerous cyst (DC) in children would initiate by teh action of other factors than developmental and at different stages of dental sac growth. Periodontitis and pulp therapy with formocresol (FC) have been suggested as aeteological factors, both promoting DC in children by irritation of the underlaying dental sacs of premolar. The purpose of this study is to analyse the pathological changes in DC of patients aged 0 to 15 years, and to compare the findings according to the anatomical site of DC and the existence of previous FC therapy. Morphological changes observed in the epithelium and the connective wall did not show clear differences between both groups of DC. The histometric measurements of epithelial changes did not show significant statistical differences of various parameters in the DC walls. These facts would not support the hypotesis of DC initiation from FC effects.
