title: Preference for using posts to restore endodontically treated teeth: findings from a survey with dentists

description: The aim of this study was to evaluate if clinical experience, whether in relation to length of practice time and/or level of specialization influences the dentist’s preference for using posts to restore endodontically treated teeth. A cross sectional study was carried out using a questionnaire with dentists (n = 276) in Pelotas, southern Brazil. Data were collected regarding clinical experience, post-graduate training, and variables related to restorations (posts/cements and use of rubber dam) for endodontically treated teeth. The data were submitted to a descriptive analysis and associations were tested. The response rate was 68%. Cast metal posts (24.53%), glass fiber posts (20.75%) and resin cement (66.67%) were the most commonly selected materials. In relation to rubber dams, 93.05% of the dentists were found not use them to lute posts. There was a significant association between the level of training of post-graduate dentists and the type of post used (p = 0.027), in that dentists without post-graduate training used cast metal posts more frequently, whereas dentists with post-graduate training reported glass fiber posts as their first choice. The results of the study showed that dentists preferred cast metal posts, glass fiber posts and resin cement. Continuing education influenced the decision of the dentists on their choice of dental posts.

title: Diode laser irradiation increases microtensile bond strength of dentin

description: Laser irradiation after the immediate application of dentin bonding systems (DBSs) and prior to their polymerization has been proposed to increase bond strength. The objective of this study was to evaluate the effect of diode laser irradiation (λ = 970 nm) on simplified DBSs through microtensile bond strength tests. Forty healthy human molars were randomly distributed among four groups (n = 10) according to DBSs used [Adper™ SingleBond 2 (SB) and Adper™ EasyOne (EO)], and the respective groups were irradiated with a diode laser (SB-L and EO-L). After bonding procedures and composite resin build-ups, teeth were stored in deionized water for 7 days and then sectioned to obtain stick-shaped specimens (1.0 mm2). The microtensile test was performed at 0.5 mm/min, yielding bond strength values in MPa, which were evaluated by two-way ANOVA followed by Tukey’s test (p &lt; 0.05) for individual comparisons. For both adhesive systems, diode laser irradiation promoted significant increases in bond strength values (SB: 33.49 ± 6.77; SB-L: 43.69 ± 8.15; EO: 19.67 ± 5.86; EO-L: 29.87 ± 6.98). These results suggest that diode laser irradiation is a promising technique for achieving better performance of adhesive systems on dentin.

title: Independent Predictors of Late Presentation in Patients with ST-Segment Elevation Myocardial Infarction

description: Abstract Background: In patients with acute ST-segment elevation myocardial infarction (STEMI), the time elapsed from symptom onset to receiving medical care is one of the main mortality predictors. Objective: To identify independent predictors of late presentation in patients STEMI representative of daily clinical practice. Methods: All patients admitted with a diagnosis of STEMI in a reference center between December 2009 and November 2014 were evaluated and prospectively followed during hospitalization and for 30 days after discharge. Late presentation was defined as a time interval &gt; 6 hours from chest pain onset until hospital arrival. Multiple logistic regression analysis was used to identify independent predictors of late presentation. Values of p &lt; 0.05 were considered statistically significant. Results: A total of 1,297 patients were included, with a mean age of 60.7 ± 11.6 years, of which 71% were males, 85% Caucasians, 72% had a mean income lower than five minimum wages and 66% had systemic arterial hypertension. The median time of clinical presentation was 3.00 [1.40-5.48] hours, and approximately one-quarter of the patients had a late presentation, with their mortality being significantly higher. The independent predictors of late presentation were Black ethnicity, low income and diabetes mellitus, and a history of previous heart disease was a protective factor. Conclusion: Black ethnicity, low income and diabetes mellitus are independent predictors of late presentation in STEMI. The identification of subgroups of patients prone to late presentation may help to stimulate prevention policies for these high-risk individuals.

title: Morphometric evaluation and planning of anticurvature filing in roots of maxillary and mandibular molars

description: This study aimed to guide the planning of anticurvature filing using pre-determined anatomical points on teeth to establish directions for proper implementation of the technique. Two hundred digital periapical radiographs of human molar teeth were selected and divided into two groups (n = 100): MX (maxillary) and MD (mandibular) molars. Mesiobuccal roots were considered for the MX group and mesial roots for the MD group. Pre-determined anatomical points required for planning the anticurvature filing on the root canal path were located, and the distances between these points obtained. The anticurvature filing was simulated in two different protocols for each group, and the region of dentin removal and the remaining dentin thickness were measured in the safety and danger zones of the root canals. Statistical analysis was carried out at a significance level of 5%. The distances between the anatomical points and the thickness of remaining dentin showed significant differences when the two groups were compared (p &lt; 0.001). No significant differences were found between the two experimental groups regarding the area of dentin removal at the root region, but differences were detected in comparison with dentin removal at the crown (p &lt; 0.001). In terms of wear produced after simulation of both anticurvature filing protocols, significant differences were verified for all regions, except for the dentin remaining at the danger zone. The radiographic location of anatomical points allows for planning and implementation of controlled and efficient anticurvature filing and can be performed in the same manner for maxillary and mandibular molars.

title: Population structure, spatial distribution and phenology of Anacardium humile A. St.-Hil. (Anacardiaceae) in cerrado stricto sensu

description: ABSTRACT This study determined the size structure, spatial distribution, and phenology of individuals from a population of Anacardium humile A. St.-Hil. in a cerrado stricto sensu area. Four sample plots (100 × 100 m each) were randomly selected in the Quilombola Kalunga land. Within the plots, we counted the number of individuals and measured the height, basal diameter, number of tree branches and recorded their location and the presence of rocky outcrops. For the phenological analysis, sixteen individuals were monitored between May 2016 and April 2017. A total of 417 individuals were inventoried, which resulted in an average density of 104.25 ind ha-1 (± 60.35). The abundance of individuals was higher in the rocky outcrops and with an aggregate spatial distribution. The population is self-regenerating. Phenological changes were concentrated in the dry season and were influenced by lower precipitation rates, maximum temperature, and relative humidity.

title: Mortality for Critical Congenital Heart Diseases and Associated Risk Factors in Newborns. A Cohort Study

description: Abstract Background: Congenital heart diseases are the most common type of congenital defects, and account for more deaths in the first year of life than any other condition, when infectious etiologies are ruled out. Objectives: To evaluate survival, and to identify risk factors in deaths in newborns with critical and/or complex congenital heart disease in the neonatal period. Methods: A cohort study, nested to a randomized case-control, was performed, considering the Confidence Interval of 95% (95% CI) and significance level of 5%, paired by gender of the newborn and maternal age. Case-finding, interviews, medical record analysis, clinical evaluation of pulse oximetry (heart test) and Doppler echocardiogram were performed, as well as survival analysis, and identification of death-related risk factors. Results: The risk factors found were newborns younger than 37 weeks (Relative Risk - RR: 2.89; 95% CI [1.49-5.56]; p = 0.0015), weight of less than 2,500 grams (RR: 2.33 [; 95% CI 1.26-4.29]; p = 0.0068), occurrence of twinning (RR: 11.96 [95% CI 1.43-99.85]; p = 0.022) and presence of comorbidity (RR: 2.27 [95% CI 1.58-3.26]; p &lt; 0.0001). The incidence rate of mortality from congenital heart disease was 81 cases per 100,000 live births. The lethality attributed to critical congenital heart diseases was 64.7%, with proportional mortality of 12.0%. The survival rate at 28 days of life decreased by almost 70% in newborns with congenital heart disease. The main cause of death was cardiogenic shock. Conclusion: Preterm infants with low birth weight and comorbidities presented a higher risk of mortality related to congenital heart diseases. This cohort was extinguished very quickly, signaling the need for greater investment in assistance technology in populations with this profile.

title: Surgical Treatment for Stress Urinary Incontinence in Women: A Systematic Review and Meta-analysis

description: Abstract Objective To compare surgical treatments for stress urinary incontinence in terms of efficiency and complications. Data Sources We searched the MEDLINE and COCHRANE databases using the terms stress urinary incontinence, surgical treatment for stress urinary incontinence and sling. Selection of Studies Forty-eight studies were selected, which amounted to a total of 6,881 patients with scores equal to or higher than 3 in the Jadad scale. Data Collection Each study was read by one of the authors, added to a standardized table and checked by a second author. We extracted data on intervention details, follow-up time, the results of treatment and adverse events. Data Synthesis Comparing retropubic versus transobturator slings, the former was superior for both objective (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.05-1.54) and subjective (OR, 1.23; 95% CI, 1.02-1.48) cures. Between minislings versus other slings, there was a difference favoring other slings for subjective cure (OR, 0.58; 95% CI, 0.39- 0.86). Between pubovaginal sling versus Burch surgery, there was a difference for both objective (OR, 2.04; 95% CI, 1.50-2.77) and subjective (OR, 1.64; 95% CI, 1.10-2.44) cures, favoring pubovaginal sling. Therewas no difference in the groups: midurethral slings versus Burch, pubovaginal sling versus midurethral slings, transobturator slings, minislings versus other slings (objective cure). Retropubic and pubovaginal slings are more retentionist. Retropubic slings have more bladder perforation, and transobturator slings, more leg and groin pain, neurological lesion and vaginal perforation. Conclusion Pubovaginal slings are superior to Burch colposuspension surgery but exhibit more retention. Retropubic slings are superior to transobturator slings, with more adverse events. Other slings are superior to minislings in the subjective aspect. There was no difference in the comparisons between midurethral slings versus Burch colposuspension surgery, pubovaginal versus midurethral slings, and inside-out versus outside-in transobturator slings.

title: Surface roughness and wear of resin cements after toothbrush abrasion

description: Increased surface roughness and wear of resin cements may cause failure of indirect restorations. The aim of this study was to evaluate quantitatively the surface roughness change and the vertical wear of four resin cements subjected to mechanical toothbrushing abrasion. Ten rectangular specimens (15 × 5 × 4 mm) were fabricated according to manufacturer instructions for each group (n = 10): Nexus 3, Kerr (NX3); RelyX ARC, 3M ESPE (ARC); RelyX U100, 3M ESPE (U100); and Variolink II, Ivoclar/Vivadent (VL2). Initial roughness (Ra, µm) was obtained through 5 readings with a roughness meter. Specimens were then subjected to toothbrushing abrasion (100,000 cycles), and further evaluation was conducted for final roughness. Vertical wear (µm) was quantified by 3 readings of the real profile between control and brushed surfaces. Data were subjected to analysis of variance, followed by Tukey’s test (p &lt; 0.05). The Pearson correlation test was performed between the surface roughness change and wear (p &lt; 0.05). The mean values of initial/final roughness (Ra, µm)/wear (µm) were as follows: NX3 (0.078/0.127/23.175); ARC (0.086/0.246/20.263); U100 (0.296/0.589/16.952); and VL2 (0.313/0.512/22.876). Toothbrushing abrasion increased surface roughness and wear of all resin cements tested, although no correlation was found between those variables. Vertical wear was similar among groups; however, it was considered high and may lead to gap formation in indirect restorations.
