          Abstract

          O objetivo deste trabalho foi caracterizar os aspectos biológicos e morfológicos de machos da mosca-dos-brotos Neosilba perezi (Diptera: Lonchaeidae). Em laboratório, o período de incubação dos ovos foi de dois dias, em média, com 55,5% de viabilidade. Criadas em dieta artificial, à base de farinha de mandioca, o tempo médio de desenvolvimento da larva recém-eclodida até a formação de pupa foi de 15 dias, e o período pupal médio foi de 23 dias. O ciclo biológico (ovo-adulto) foi de aproximadamente 40 dias. Os ovos são de coloração branca, forma elíptica e têm 960 ± 5,30 µm de comprimento e 290 ± 1,30 µm de largura na região central; as larvas de aspecto vermiforme, terceiro ínstar, são de coloração branco-leitosa e medem ± 10 mm de comprimento (3º ínstar).

          The aim of this study was to determine biological and morphological patterns of the male shoot fly, Neosilba perezi (Diptera: Lonchaeidae). Under laboratory conditions, the incubation period of eggs took two days, on average (viability of eggs: 55.5%). Bred on an artificial diet, based on cassava flour, the mean time of development of the newly hatched larvae to pupa formation occurred in 15 days, and the average pupal period took 23 days. Finally, the biological cycle, from egg to adult, lasted approximately 40 days. The eggs are white colored, have an elliptical form and are about 960 ± 5.30 µm long and 290 ± 1.30 µm large in the central region; the vermiform larvae, third instar, are milky white and are ± 10 mm long (3rd instar).

          Atraumatic restorative treatment: clinical, ultrastructural and chemical analysis.

          With the purpose of checking, in vivo, the effect of atraumatic restorative treatment (ART) on the remaining demineralized dentin, 12 primary molars with deep occlusal lesions from children with ages ranging from 3 to 7 were evaluated. After lesion excavation, and before glass ionomer cement placement, dentin samples were collected from the pulpal wall of the cavity. After 3 months, the restorations were removed and new samples were collected. Six microareas of each sample were analyzed by X-ray energy dispersion spectrometer. Samples obtained before treatment were infected and intertubular dentin had a loosely organized collagen matrix, with well-defined collagen fibers. Following treatment, in addition to a drastic reduction of the amount of bacteria, the intertubular dentin was denser, with more compact and closely packed collagen fibers. An increased calcium concentration was observed in dentin collected after treatment (p < 0.001), suggesting tissue remineralization, but fluoride was not detected. We conclude that ART allows a one-session approach, with the purpose of creating more favorable conditions for the healing process. Copyright 2002 S. Karger AG, Basel
