Planning and clinical strategy in direct composite restorations

Patients are seeking increasingly the expertise of dental surgeons for esthetic dental improvement. The dental surgeons should know the restorative materials and techniques in order to optimize the clinical practice and to obtain satisfactory results. Also the dentist should know the average heights and widths of the anterior teeth to detect the esthetic disharmony and to eliminate it for reproducing the correct dental anatomy. Thus, this study aimed to describe a clinical case report of direct restoration using the palatal barrier technique.

Health professionals ethical and legal liability on patient’s inadequate clarification in order to obtain free and informed consent

It is required that patients are provided information about therapeutic possibilities, showing the risks, benefits, prognosis and costs of each possible and indicated alternative. This is an ethical and legal resolution. However, health professionals possess the clinical/technical/scientific knowledge and determine what information will be (or not) provided. The patient in question decides to undergo a treatment, providing his/her free and informed consent on the basis of the data presented. Unfortunately, some professionals may not provide all the information necessary for making an informed decision or, after obtaining the consent of the patient, may provide him information that causes the patient to give up on the treatment initially accepted. Such information, if relevant, and not a supervening fact, should have been provided initially. However, the information may not be entirely true, and bring the patient, for instance, to decide based on inadequately presented risks. The craniofacial rehabilitation of the temporomandibular joint (TMJ) by means of TMJ prosthesis, is indicated in many situations. Often, patients in need of such prostheses have aesthetic and functional problems and the rehabilitation expectations run high. This work presents a case and discusses ethical and legal issues, including the liability of partial and inadequate information to a patient.

Studies on the application of Myceliophthora thermophila JCP1-4 cellulases cocktail on sugarcane bagasse pretreated by different methods

The hydrolysis step for sugar production in biorefineries is crucial for the sequential processes involved and cellulases cocktails behave differently according to the pretreatment employed. In this study, the application of the cellulases cocktail produced by the fungus Myceliophthora thermophila JCP1-4 was studied on the saccharification of sugarcane bagasse pretreated by ozonolysis and thermic ferric nitrate (TFN), and the results were compared with commercial enzymes (Novozymes Celluclast 1.5L, Novozym 188). The fungal cellulases cocktail hold an activity of FPU:β-glucosidase of 1:4(U/mL); time, temperature, FPU by g of cellulose load and percentage of dry matter (DM) were studied. The analysis of central composite design of TFN pretreated showed that fungal cellulases works better in DM values of 3–3.5% (4.5% for commercial), temperatures higher than 50 °C (<45 °C for commercial) and 15FPU for both; commercial enzymes yielded 7.78 g/L of reducing sugars and the fungal enzymes 5.42 g/L. With the ozone pretreated, the fungal enzymes presented a higher thermostability with faster kinects, being able to produce 5.56 g/L of reducing sugars (60 °C, 8 h), against 5.20 g/L for commercial enzymes (50 °C, 24 h), (10FPU, 3%DM for both). The FPU derivate analysis revels better yields with 7.5FPU, and the increase of DM to 7.5% resulted 13.28 g/L of reducing sugars.
