The authors analysed the simultaneous effects of the dimensional and weight alteration of resins utilized for esthetic facets submitted to warehousing conditions and periods of time. The resins showed different behaviour and a neat correlation between dimensional alteration and weight. The condition of immersion promoted dimensional alteration 50% lower and an alteration of weight three times higher.

Isolamento e caracterização de candida albicans e outras leveduras de águas de recreação não marinha e de materiais clínicos

Candida albicans and other yeasts from recreational water or clinical materials were isolated. Sixty-six water samples, originating from eight swimming pools and five lakes with beaches were examined for the presence of these yeasts, by a membrane filter method and 'pour plate' technique. Sixty-two clinical materials from suspected cases of candidiasis were studied in the same period. Rhodotorula sp and C. albicans were more frequently isolated from lakes and swimming pools, respectively; C. albicans and C. parapsilosis from clinical materials. From 44 samples of C. albicans, 90,9% were serotype A, and 9,1%, serotype B; C. albicans from recreational waters belong only serotype A. No difference was observed in the M.I.C. of C. albicans strains from waters and clinical materials. All strains were susceptible to the antifungal drugs tested.

Liberação de mitomicina C - Influência de diferentes materiais

Purpose: To evaluate the quantity of Mitomycin C discharged from different materials with the same size, potentially used in the application of this medicine accessible in the surgery center of an Universitarian Hospital. Material and Method: It was studied 20 fragments with 5 to 5mm, from each 5 materials: Lyostypt, Weck sponge, absorbable cloth which is used to clean, cotton plate and of cotton swab concerning the saturation capacity and the quantity of mitomicyn discharged. In the first stage, it was studied the saturation capacity from each material. In the second stage, it was applied 0,1 ml solution of Mitomicyn C (0,5 mg/ml) and it was measured the biggest discharge halo in the filter paper and the discharged quantity (the difference between the weight before and after the medicine discharge). Results: The absorveble capacity from each material varied from 0,144 ml (absorbable cloth) to 0,216 ml Weck sponge. The discharge of Mitomicyn C was varied too, the biggest was the cotton plate and absorbable cloth. The Weck sponge and the cotton (of cotton swab) discharges the same quantity. Conclusion: The different materials discharged different quantities of Mitomicyn C. This can explain the different results of the trabeculectomy with Mitomicyn C. The surveys must inform not only the material used to apply the mitomycin C but the volume used too. Because the same values of mitomycin C liberation, cotton may substitute Weck sponje in trabeculectomy.

Comparação entre o sistema Autoścan-4 e métodos convencionais na identificação de bacilos Gram-negativos não fermentadores, isolados de materiais clínicos de pacientes em Presidente Prudente - SP

Ninety eight strains of glucose-nonfermenting Gram-negative bacilli were analyzed and isolated from several clinical materials of 95 patients admitted at the Dr. Domingos Leonardo Cerávolo University Hospital and three from outpatients. All of them were assisted in the Laboratory of Clinical Analysis of Unoeste University, Presidente Prudente, SP, from the period of October of 1999 to April of 2001. In this work, the level of agreement between the semi-automated commercial system AutoScan-4 and the conventional system for the identification of those bacteria were studied comparatively. There was agreement in 81 (82.7%), showing that both methodologies are useful for identification; partial agreement in six strains (6.1%) and disagreement in 11 (11.2%). The comercial system did not identify nine (9.2%) of the strains and reported them as very rare biotypes.

Estudo das características morfológicas dos pites nos materiais resistentes à corrosão

This paper has as a purpose a new alternative technique development to characterize pitting corrosion evolution, aiming classification, size and determination of morphological parameters which rule pits increase. In this case, the method will be applied to the 304 ABNT stainless steel, thermally treated and exposed to different times in salt spray. Different 304 steel conditions, rolled and thermally treated have exhibited similar geometry, predominantly conic, near-conic and irregular pits. On rolled steel, pits width increases faster than height; however, on thermally treated steel, pits are found to increase in height.

Padrão de sensibilidade aos antimicrobianos de bacilos gram-negativos não fermentadores isolados de materiais clínicos de pacientes em Presidente Prudente - SP

The aim of this study was the assessment of isolation frequency and antimicrobial susceptibility pattern of nonfermenting Gram-negative bacilli. Ninety eight strains of nonfermenting Gram-negative bacilli, isolated from several clinical materials of patients admited at the Dr. Domingos Leonardo Cerávolo University Hospital and at Dr. Odilo Antunes Siqueira State Hospital, as well as from every outpatient; assisted at Laboratory of Clinical Analysis of Unoeste University, Presidente Prudente, São Paulo, in the period of October 1999 to April 2001 were analyzed. The most frequent species were Pseudomonas aeruginosa (65.3%) and Acinetobacter baumannii (23.5%). The frequency of the other isolated species was smaller than 2.5%. In the antimicrobial susceptibility tests, the two species more prevalent showed high resistance. The antibiotic most active in vitro was the imipenem, with 79.6% in microdiluition method, and 76.6% in diffusion method, for Pseudomonas aeruginosa strains and 100.0% in both microdiluition and diffusion methods, for Acinetobacter baumannii. The cephalosporins of third generation, the ciprofloxacin and the aminoglycosides, presented percentage of susceptibility varying from 22.4 to 69.7%. These results bring implications to the emergency use of the antimicrobial agents in the treatment of patients with severe infection.

Valores Referenciais para Procedimentos Odontológicos (VRPO) em Ortodontia

Introduction: The cost of orthodontic treatment is a very important issue. The aim of this study was to analyze the current Indicative Values for Dental Procedures (IVDP) for orthodontic procedures. Methods: Laws, dental entities papers and scientific literature were utilized. Results: Laws are too general and only offer abstract parameters when define remunerations. Current IVDP vary in the same State, according to the consultant entity. Dental entities interpret that general clinicians can practice Corrective Orthodontics, but new scientific studies begin to question this understanding. The Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR) suggests that IVDP for orthodontic specialty must be formulated. Conclusion: Current IVDP are not standardized and are below the correct values for orthodontic procedures, because they are the mean of general clinicians and orthodontists remunerations; and ABOR is legally and ethically supported to claim specific IVDP for orthodontic specialty.

Reprodutibilidade de medidas antropométricas estáticas de graduandos de odontologia e de mochos odontológicos

Objective: To evaluate the intraexaminer reproducibility of static anthropometric measurements of undergraduate dental students as well as the characteristics and regulating measurements of the dental stools used by them. Methods: Forty volunteers and 6 types of dental stools were evaluated. For the anthropometric measurements the employed equipments were: an adapted office chair, aflexible measuring tape with two adapted rods, a metallic device with a 90 degree central angle, string, a 35 x 24 cm rectangular wooden board, isolating tape and crepe tape. In order to standardize the position of the adapted office chair and the volunteers' feet, the floor was marked with the isolating and crepe tapes. A string was attached to the waist of each volunteer to mark the area corresponding to the kidney region making it possible to measure the seat-renal region area. The examined anthropometric measurements were height, trunkcephalic heigh, sacral-popliteal distance (OK?), hip width, popliteal height and the seat-renal region height. The evaluated characteristics of the dental stools relative to the seat were depth, horizontal width and minimum/maximum height. The back of the dental stool was evaluated as for the minimum/ maximum height adjustment. The anthropometric and dental stool measurements were obtained by a single examiner at two moments with a 1-week interval between the evaluations. Intra-class correlation coefficient (ρ) was used to estimate the intraexaminer reproducibility. Results: Excellent reproducibility was observed for all anthropometric measurements obtained (ρ=0.99) as well as for all dental stools evaluated (ρ=0.99). Conclusion: The method used to obtain the anthropometric and dental stools measurements was reproducible and can be used reliably.
