The Effects of Short Term Intracanal Medicaments on the Fracture Resistance of Root in Pulp Revitalization Procedure

Introduction: The objective of this study was to evaluate the effects of short term intracanal medicaments on the fracture resistance of root in simulated necrotic immature teeth in pulp revitalization procedure. Methods and Materials: Bovine teeth (n=180) were selected, sectioned coronally and apically and then, internally fragilized. Intracanal medicament groups were arranged as follows: “Triple Antibiotic Paste” (TAP) group (n=60), “Calcium Hydroxide” (CH) group (n=60) and the control group (n=60). No medication was used in the control group. Fracture resistance tests were performed after 7, 14, and 21 days. At allocated intervals, 20 teeth from each group had fractured. The Kruskal-Wallis and Mann-Whitney tests were performed to verify the effects of the employed medicaments at each time point. Friedman test and Wilcoxon signed-rank test were also performed to verify the association between time and fracture resistance. The level of significance was set at 0.05. Results: After 7 days, there was no statistical difference between groups (P=0.376). Intragroup analysis revealed that, after 21 days, the TAP group (P=0.015) and the CH group (P=0.006) presented a statically significant reduction in fracture resistance comparison with 7 days. Statistical difference was not verified for the control group after 7, 14 and 21 days (P=0.25). There was no statistical difference between CH group and the control group after 7, 14 and 21 days (P>0.05). The reduction was significant for TAP after 14 and 21 days (P=0.018, P=0.033 Respectively). Conclusions: This in vitro study showed that the duration at which TAP and CH remained in the root canal influenced the fracture resistance of bovine teeth with simulated incomplete root formation.Keywords: Calcium Hydroxide; Endodontics; Regeneration; Triple Antibiotic Past

Orthodromic Atrioventricular Tachycardia in Wolff-Parkinson-White Syndrome with Two Accessory Pathways Participation during the Same AVT

Case report of a 49-year-old patient with Wolff-Parkinson-White syndrome, very symptomatic, with apparent parahisian pathway who, during an electrophysiological study, presented orthodromic atrioventricular tachycardia, featuring two accessory pathways, retrogradely, the parahisian pathway and a hidden left posterolateral pathway, during the same tachycardia, alternating the retrograde pathway of tachycardia without interruption

AUTOMATIC METHOD FOR GLAUCOMA CLASSIFICATION USING TEXTURE ANALYSIS, XGBOOST AND GRID SEARCH

Glaucoma is an irreversible pathology, generated by increased intraocular pressure. Early detection is critical and can pre- vent total vision loss. Clinical examinations are commonly used to detect the disease. Still, the time and cost of identi- fication is quite high. This paper presents a computational methodology that aims to assist specialists in the discov- ery of glaucoma through Computer Vision techniques. The proposed methodology consists in the application of several texture descriptors combined with a parameter optimiza- tion done through Grid search with the XGBoost classifier. A result was obtained with accuracy of 82.37% and ROC of 82.08%

a study from ecological theory and social network analysis perspective

The objective of the present study was to analyze and compare the setter's decision-making (DM) in the offensive construction of the side-out (attack from the reception) in high-level men's volleyball. The sample consisted of the analysis of 132 games of the Brazilian men's volleyball Super-League 2021/2022, with 22 games for each team. The results showed that the eigenvector values were higher for setting to position 3, central attacker next to the setter, simple block, and obtaining the attack point. In addition, the setter's DM was similar between teams, suggesting that the game strategies aim to provide subsidies for the setter to make the decisions according to the game context in a flexible way and generate benefits for the attackers about the number of blockers, being that under ideal conditions and due to the lifter's correct choices in distribution, central blockers avoid anticipating the setting, and this fact allows the conditions of a single block or double-broken blocks in most cases. As a practical application, setting for the central attacker in position 3 becomes an interesting option for point acquisition and is capable of influencing the number of blockers, as well as the optimal blocking condition. Another application would be for the central attacker to position themselves close to the setter, a strategy that would enable the use of the "pipe" attack in other areas of the court with lower defensive blocking power.9E1A-F9DD-3EB8 | Filipe Manuel ClementeN/

Quantitative and qualitative diagnostic of urban trees squares in Aracaju, SE, Brazil

Aracaju is a city that was planned with geometric precision and simplicity. Since its settlement, it has gone through constant changes in its urban environment. Due to these changes, fewer green areas remain in the urban environment. Well-planned urban afforestation is very important, once trees provide benefits to the city in ecological (climate and pollution), biological (physical health of human beings) and psychological (mental health of population) processes. However, the absence of afforestation planning and the use of inappropriate species are the main obstacles to achieving these benefits. This study was carried out to evaluate the floristic composition of twenty-two main squares in Aracaju-SE, as a way to know the current status and allow some interventions to improve the technical adequacy of urban green space. The floristic survey was conducted by means of a Census, from September 2006 until July 2007, in each square making the recognition and identification of all trees present using traditional methods and herborization.Aracaju foi uma cidade planejada com simplicidade e rigor geométrico. Desde a sua fundação, ela vem passando por constantes alterações, havendo cada vez menos áreas verdes no ambiente urbano. A arborização urbana bem planejada é muito importante, pois as árvores trazem benefícios à cidade nos processos de ordens ecológica (clima e poluição), biológica (saúde física do homem) e psicológica (saúde mental do homem). Porém, a falta de planejamento dessa arborização e o uso inadequado de algumas espécies são empecilhos para se atingirem esses benefícios. Dessa forma, este trabalho foi realizado com o objetivo de avaliar a composição florística de 22 praças de Aracaju, SE, como forma de conhecer a atual situação de sua arborização e possibilitar intervenções para melhorar a adequação técnica do espaço verde urbano. O levantamento florístico foi realizado através de censo, no período de setembro de 2006 a julho de 2007, em cada praça, com o reconhecimento e identificação de todos os indivíduos arbóreos, utilizando-se as técnicas tradicionais de coleta e herborização. Realizou-se a identificação das espécies com o auxílio de literatura específica. Foram identificados 1.290 indivíduos, distribuídos em 20 famílias botânicas, 46 gêneros e 64 espécies, sendo nove espécies não identificadas. Das espécies identificadas, 58% são exóticas no território brasileiro e 42%, espécies nativas. As praças apresentam similaridade entre si, com coeficiente de Jaccard variando de 0,00 a 0,66, e a Praça Almirante Tamandaré e a Praça Graccho Cardoso foram as de maior similaridade (66%).Viçosa, M
