Infrared spectroscopy is one of the most widely used techniques for measurement of conversion degree in dental composites. However, to obtain good quality spectra and quantitative analysis from spectral data, appropriate expertise and knowledge of the technique are mandatory. This paper presents important details to use infrared spectroscopy for determination of the conversion degree.

A inclusão da criança com necessidades especiais na visão de berçaristas

A inserção das crianças de zero a 18 meses em creches poderá estimular o seu desenvolvimento motor e perceptocognitivo, podendo essa fase ser considerada a primeira da educação inclusiva. Objetivou-se verificar as concepções das profissionais do berçário relativas à inserção da criança com necessidades especiais na rotina de atividades desenvolvidas. Foram entrevistadas sete berçaristas da Secretaria Municipal de Educação de Bauru. Os dados, organizados segundo categorias analíticas: conceitos relativos ao processo de inclusão, benefícios para a criança e diferenças entre as crianças nessa faixa etária, foram submetidos à análise qualitativa. Os resultados mostraram que a inclusão de crianças com necessidades especiais é vista com reservas, explicitando ideias preconcebidas sobre a deficiência. Eles se justificam pela falta de conhecimento do desenvolvimento infantil e dos fatores que o envolvem, bem como pelo fato de os profissionais vincularem suas atividades às experiências pessoais.

Nasalance and nasality at experimental velopharyngeal openings in palatal prosthesis: a case study

The use of prosthetic devices for correction of velopharyngeal insufficiency (VPI) is an alternative treatment for patients with conditions that preclude surgery and for those individuals with a hypofunctional velopharynx (HV) with a poor prognosis for the surgical repair of VPI. Understanding the role and measuring the outcome of prosthetic treatment of velopharyngeal dysfunction requires the use of tools that allow for documenting pre- and post-treatment outcomes. Experimental openings in speech bulbs have been used for simulating VPI in studies documenting changes in aerodynamic, acoustic and kinematics aspects of speech associated with the use of palatal prosthetic devices. The use of nasometry to document changes in speech associated with experimental openings in speech bulbs, however, has not been described in the literature. Objective: This single-subject study investigated nasalance and nasality at the presence of experimental openings drilled through the speech bulb of a patient with HV. Material and Methods: Nasometric recordings of the word "pato" were obtained under 4 velopharyngeal conditions: no-opening (control condition), no speech bulb, speech bulb with a 20 mm(2) opening, and speech bulb with 30 mm(2) opening. Five speech-language pathologists performed auditory-perceptual ratings while the subject read an oral passage under all conditions. Results: Kruskal-Wallis test showed significant difference among conditions (p=0.0002), with Scheffe post hoc test indicating difference from the no-opening condition. Conclusion: The changes in nasalance observed after drilling holes of known sizes in a speech bulb suggest that nasometry reflect changes in transfer of sound energy related to different sizes of velopharyngeal opening.

Nasoendoscopy of velopharynx before and during diagnostic therapy

Nasoendoscopy is an important tool for assessing velopharyngeal function. The purpose of this study was to analyze velar and pharyngeal wall movement and velopharyngeal gap during nasoendoscopic evaluation of the velopharynx before and during diagnostic therapy. Nasoendoscopic recordings of 10 children with operated cleft lip and palate were analyzed according to the International Working Group Guidelines. Ratings of movement of velum and pharyngeal walls, and size, location and shape of gaps were analyzed by 3 speech-language pathologists (SLPs). Imaging was obtained during repetitions of the syllable /pa/ during a single nasoendoscopic evaluation: (a) before diagnostic therapy, and (b) after the children were instructed to impound and increase intraoral air pressure (diagnostic therapy). Once the patients impounded and directed air pressure orally, the displacement of the velum, right, left and posterior pharyngeal walls increased 40, 70, 80, and 10%, respectively. Statistical significance for displacement was found only for right and left lateral pharyngeal walls. Reduction in gap size was observed for 30% of the patients and other 40% of the gaps disappeared. Changes in gap size were found to be statistically significant between the two conditions. In nasoendoscopic assessment, the full potential of velopharyngeal displacement may not be completely elicited when the patient is asked only to repeat a speech stimulus. Optimization of information can be done with the use of diagnostic therapy's strategies to manipulate VP function. Assuring the participation of the SLP to conduct diagnostic therapy is essential for management of velopharyngeal dysfunction.

As implicações sociais da deficiência auditiva adquirida em adultos

O objetivo deste estudo foi analisar as implicações da surdez adquirida em adultos, na vida familiar, social e no trabalho, com uma abordagem qualitativa. Foram selecionadas 27 pessoas residentes em Bauru-SP, com diagnóstico de perda auditiva de manifestação súbita na faixa etária de 18 a 60 anos, matriculados no Hospital de Reabilitação de Anomalias Craniofaciais (HRAC/USP) entre janeiro de 2000 e fevereiro de 2005, sendo entrevistados 16. Utilizaram-se a entrevista e a análise de conteúdo. Constatou-se: a perda auditiva ocorreu entre os 40 e 44 anos, 37,5%; 62,5% dos que perderam a audição eram do sexo masculino, 62,5% não tinham o ensino fundamental; 62,5% eram da classe Baixa Superior; 75% apresentaram perda auditiva bilateral, 18,75% de grau moderado/profundo. Dos 13 que estavam trabalhando quando perderam a audição, 30,77% pararam de trabalhar e 15,38% mudaram de profissão. Foram relatadas situações como: afastamento do trabalho, demissão a pedido e demissão pelo empregador, dificuldade de aceitação, cobranças, falta de esclarecimentos e desconhecimento dos próprios profissionais de saúde. Os dados sugerem a necessidade dos recursos de reabilitação, de apoio terapêutico, respeito e alternativas de conhecimentos.

Evaluation of tissue response to periodontal dressings: Histological study in tooth sockets of rats

Although the use of periodontal dressings is currently limited, there are some indications for their use. Selection of any material that will have direct contact with live tissues, such as periodontal dressings, should be careful in order to allow surgical wound healing. The aim of this study was to evaluate the intensity of inflammatory response and bone formation in tooth sockets of rats after implantation of three periodontal dressings. After removal of the right maxillary incisors of 84 male rats, each tooth socket received implantation of a polyethylene tube, 63 of which were filled with non-eugenol periodontal dressing and the remaining 21 tubes remained empty (control group). Histological evaluation assessed the intensity of inflammatory response and presence and location of bone tissue formation at postoperative periods of 7, 14 and 28 days. Statistical analysis was performed by the Kruskal-Wallis test at 5% significance level. Regarding the inflammatory infiltrate, at 28 days, there was statistically significant difference between one of periodontal dressings and control group (p < 0.05). Analysis of postoperative periods, showed that the control group presented statistically significant reduction in the inflammatory infiltrate comparing the 14- and 28-day periods (p < 0.05). Regarding bone tissue formation, there was difference in control group between the 7- and 28-day periods (p < 0.05). Within the experimental conditions, it may be concluded that no differences were found in the inflammatory response among the groups at 7 and 14 days and that Voco pac (TM) dressing induced a more intensive inflammatory reaction at 28 days.

Experimental periodontal disease treatment by subgingival irrigation with tetracycline hydrochloride in rats

Objective: The aim of this study was to compare subgingival irrigation with tetracycline hydrochloride (TTC-HCL) as adjunctive treatment to scaling and root planning (SRP) on induced periodontitis in rats. Material and Methods: In 60 rats, periodontal disease was ligature-induced at the mandibular left first molar. After 7 days, the ligature was removed and all animals were submitted to SRP, and divided into 2 groups according to the following treatment: C (n=30) - subgingival irrigation with 1 mL of saline; T (n=30) - subgingival irrigation with 1 mL of TTC-HCL (50 mg/mL). Ten animals in each group were euthanized at 7, 15 and 30 days posttreatment. The histometric values were statistically analyzed (p<0.05). Results: In the histometric analysis, at 7, 15 and 30 days, Group T (0.72+/-0.05 mm(2), 0.57+/-0.14 mm(2), 0.62+/-0.07 mm(2)), showed less bone loss (p<0.05) than Group C (1.35+/-0.25 mm(2); 1.40+/-0.31 mm(2); 1.29+/-0.27 mm(2)), respectively. Conclusions: Subgingival irrigation with TTC-HCL was an effective adjunctive treatment for periodontal disease induced in rats.
