title: Evaluation of the effect of chlorhexidine and sodium hypochlorite in adhesive cementation of fiber posts - in vitro study

description: Abstract Introduction The attachment of fiberglass posts is achieved through an adhesive process. Failures in adhesion may occur due to the hydrolytic degradation of the adhesives, or to the degradation of the collagen fibres of the hybrid layer by intrinsic enzymes. Objective To evaluate the effect of chlorhexidine and sodium hypochlorite treatment on bond strength to dentin. Material and method Thirty bovine roots were randomly distributed into 3 groups (n=10): a) Control, b) 2% Chlorhexidine, and c) 5% Sodium Hypochlorite. Next, RelyX® ARC resin cement was used to cement the post. Each specimen resulted in samples from the three root thirds that were submitted to the pushout test (MPa) at 24 hours and 12 months. Bond strength values were analysed using the Kolmogorov-Smirnov, 3-way ANOVA and Tukey tests. The fracture mode of the pin was also analysed using stereomicroscopy. Result There were no significant differences between treatments at the immediate time (p=0.0644) or in the interaction of factors (p=0.1935). After one year, the experimental groups showed no significant differences in bond strength in relation to the control group, with the exception of the cervical third of the chlorohexidine group in which there was a significant loss of adhesion. As for the fracture mode, there was a predominance of the mixed type in all groups and thirds. Conclusion The use of chlorhexidine or hypochlorite provides neither benefits nor losses in the adhesive bond strength of fiberglass posts. However, there is an influence of the root thirds, with the worst bond strength in the apical third.

title: Characterization of peanut cultivars to damage Stegasta bosquella (Chambers, 1875) (Lepidoptera: Gelechiidae)

description: ABSTRACT: We evaluated the strength of four growth habit of peanut cultivars creeping and five cultivars of erect growth habit to damage Stegasta bosquella (Chambers, 1875) (Lepidoptera: Gelechiidae) under field conditions during the rainy season, in the years 2009/2010 and 2010/2011. The cultivars used in the experiments were: IAC 147, IAC 213, IAC Caiapó and IAC Runner 886 (runner) and IAC Tatu ST, IAC 5, IAC 8112, IAC 22 e IAC 88-1 (erect). The design adopted was randomized blocks with split plot over time, and four replications. For infestation of S. bosquella , weekly evaluations were done 18 to 67 days after emergence (DAE), with caterpillars count and damage assessments. For counting the number of shoots per plant, they collected up five plants per plot from the 30, 60 and 90 DAE. Regardless of cultivating major infestations of S. bosquella occur from 53 to 67 DAE. The IAC Runner 886 cultivar has the highest emission apical shoots a desirable feature in plant defense in relation to S. bosquella .

title: Immunohistochemical analysis of Ki-67 and α-SMA in odontogenic keratocyst, ameloblastoma and pericoronal follicle

description: Abstract Introduction Ameloblastomas (AM) are considered the most common odontogenic tumors, with great clinical importance linked to its locally aggressive, infiltrative, and recurrent behavior. The odontogenic keratocyst (OK) represents a peculiar cyst that also draws attention because of its aggressive behavior and high rates of local recurrence. Objective The aim of this study was to evaluate the cell proliferation index and the presence of myofibroblasts in AM and OK using Ki-67 and α-SMA antibodies, respectively. Methodology Fifteen cases of AM and 24 cases of OK were selected for immunohistochemical investigation of the proteins α-SMA and Ki-67. A group of 7 pericoronal follicles (PF) was included as control for normal odontogenic tissue. The mean percentage of positive cells was calculated for each protein. Result Kruskal-Wallis test for both markers showed that expression was higher in OK, when compared to AM and PF. Mann-Whitney test showed no statistical difference when comparing the expression of both markers between the subtypes of AM. Conclusion Elevated expression of Ki-67 and α-SMA in OK may be associated with the aggressive clinical behavior of this cyst in comparison to other development cysts. The similar expression of the markers observed among AM and PF cases, as well as among subtypes of AM, may indicate that other factors, besides proliferative potential, are associated with the aggressive behavior of AM.

title: Antiretroviral treatment: adherence and the influence of depression in users with HIV/Aids treated in primary care

description: ABSTRACT Adherence to treatment is one of the major challenges to HIV (Human Immunodeficiency Virus) treatment, being depression a factor that impacts on it. The research aimed to identify if depression interferes with adhesion. A multi-approach method for adherence, open interview and Beck Depression Inventory were used for depression screening. The relationship between depression and nonadherence was not found, although the prevalence of depression reached 22.24%. Some patients assume fear of stigma and difficulty in following antiretroviral treatment due to the drug adverse effects. Also a social protection network was perceived as crucial as was the necessity to build a care network.

title: Dentists’ knowledge about the relationship between temporomandibular dysfunction and oclusal factors

description: Abstract Introduction Current scientific evidence has shown that treatment for temporomandibular disorder should follow a conservative approach that is adapted to the patient’s psychosocial status. However, treatments aiming at occlusal changes have been used for years by dentists and the abandonment of these paradigms is essential for the development of dentistry. Objective The aim of this study was to evaluate the knowledge of dentists on the relationship between temporomandibular disorder (TMD) and occlusal factors. Material and method A previously published questionnaire was sent to the dentists registered at the Regional Council of Dentistry of Piauí, Brazil (n = 2,500) with data about the professional, their training and knowledge about TMD and occlusal factors. The consensus of the current literature, “gold standard”, was compared with the answers obtained. The data were analyzed descriptively and through chi-square test and odds ratio (p &lt;0.05). Result Five hundred and five dentists answered and 434 composed the sample. The majority of the participants was women (72.3%) with 7.2 (± 6.63) years of education and worked in the public-private sector (39.0%). The dentists were divided into Group 1 (GEsp.): specialists in TMD, dental prosthesis and/or orthodontics (n = 234) and Group 2 (GClin.): clinicians and other specialists (n = 200). GEsp. and GClin. presented similar responses for half of the questions. Four (of six) were answered in disagreement with the gold standard: occlusal factors, interference in the balance, orthodontic therapy and occlusal adjustment were little known. GEsp. presented greater knowledge with a significant difference in relation to GClin. regarding TMD and occlusal interferences (odds ratio = 2,341 (1,305-4,202), p = 0.004). Conclusion It can be concluded that the dentists presented deficiencies in the knowledge of the relationship between TMD and occlusal factors. Dentists specialists in TMD, dental prosthesis and/or orthodontics did not demonstrate a higher level of knowledge when compared to the others.

title: Socio-economic factors affecting the consumer provision in meat with certification of origin Belo Horizonte, Minas Gerais, Brazil

description: ABSTRACT: The present study aimed to verify the influence of socioeconomic factors in the provision of 407 consumers in supermarkets in the city of Belo Horizonte, Minas Gerais, Brazil, in purchasing beef with certification of origin and to verify the inherent characteristics of the product that help the consumer at the time of purchase, considering their prior knowledge about traceability and certification of origin. A descriptive analysis of all variables was performed and a univariate analysis was subsequently conducted by chi-square test. The variables were added in the multiple logistic regression model Generalized Estimating Equations (GEE), and for all variables in the final model (p ≤ 0.05) the risk was calculated by the adjusted odds ratio (OR) to a range of 95% confidence. All socioeconomic factors examined (gender, age, income and education) influence the willingness of consumers to purchase beef with certification of origin. The most important intrinsic attributes in decision making when buying meat were the color, softness, odor and little amount of fat, whereas the extrinsic attributes were price, quality seal and stamp of the SIF. Most of the consumers know the correct concept of traceability and believe that the greatest benefit of the traced meat is to be safer and to avoid the risk of foodborne illness; and the disadvantage is to be a more expensive product than the conventional.

title: Orthodontic and pediatric dental treatment approach in patient with multiple dental anomalies

description: The purpose of this clinical case report is to discuss the approach to oral rehabilitation of a patient with severe dental alterations such as enamel hypoplasia, change in shape, supernumerary tooth, dental ankylosis, agnesia and crowing in the incisor region. All of these problems compromised not only the esthetical and functional aspects of this patient, but his social relationships as well. Thus integrated planning between Pediatric Dentistry and Orthodontics made it possible to provide the best treatment alternative to recover the patient's stomatognathic system. Esthetic restorations were performed in the anterior tooth region with the use of resin composites, in addition to the use of removable orthodontic appliances, associated with serial extractions and supernumerary tooth removal. There were significant improvements in the esthetic and functional aspects of dentition, in addition to the patient demonstrating good evolution in his psychosocial condition, as he smiled and was more communicative during each follow-up appointment, also according to his mother's reports.

title: Analysis of apical root canal disinfection prepared at three different working lengths with either continuous or reciprocating movement systems and two irriganting substances: in vitro study

description: Abstract Introduction The preparation of the root canal is fundamental for the success of endodontic therapy, especially the apical third, since it contains the root foramen, where the endodontium and the periradicular tissues communicate. Objective The present study evaluated the contamination of the apical third after the root canal instrumentation in three different lengths, through two types of automated instrumentation (continuous or reciprocating rotating) and two irrigating substances used. Material and method Sixty-six biradicular maxillary premolars were selected, which had their crowns removed and roots separated, totaling 132 specimens. In the first phase, six experimental groups were divided according to the length of instrumentation (before, beyond and in the radicular foramina) and the type of instrumentation (continuous or reciprocating rotatory) with sodium hypochlorite as irrigator. In the second phase the same protocol was repeated, using sodium chloride as the irrigant. In order to confirm the results, two control groups were created: positive and negative, each with six specimens. Result For the same irrigant, no differences were found between the groups with continuous or reciprocating rotational instrumentation in their different working lengths. The groups irrigated with hypochlorite showed no bacterial growth, whereas those irrigated with sodium chloride remained contaminated after instrumentation. Conclusion Mechanical action of endodontic instruments, without bactericidal irrigating substance, does not promote the apical root canal disinfection and the choice of kinematic type of endodontic instruments (continuous or reciprocating rotatory) does not significantly influence the reduction of bacteria within the root canals as well instrumentations ranging from one millimeter before to one millimeter beyond the foramen also did not present differences in the reduction of bacteria in this research.
