Mangrove forests physiography was studied to understand the colonization process. Two transversals were made perpendicular to the Tavares River and twelve plots were established along an inundation flux. The quadrats were delimited and took structural data was collectd on specimens density, tree stature and diameter breast height. Avicennia schaueriana was the dominant species and Rhizophora mangle and Laguncularia racemosa were registries. Nine quadrats was dominated by A. schaueriana, two of them showed R. mangle and one, L. racemosa. A. schaueriana is the most adapted species, dominating in basal area and it is the first species to colonize the plots. Our structural data give us some classification of the stand colonization, being able to differentiate forest in colonization, development and mature stages.
Objective: To evaluate levels of anxiety in children and adolescents related to age and experience of visits to the dentist using the modified Venham Picture Test (VPTm). Material and Methods: This is a quantitative cross-sectional study with convenience sample. Children and adolescents of both sexes, subdivided into age groups of 6-9 years (A1 and A2) and 10-13 years (B1 and B2), in the waiting room of a Dental Clinic, were grouped according to the experience of visits to the dentist (have been to the dentist / have never been to the dentist). Descriptive statistics were mean, standard deviation and frequency of cases. The Kolmogorov-Smirnov (K-S) was used for normality analysis, with 95% significance level. Inferential statistics was performed using the Chi-Square and Mann-Whitney tests, with p<0.05. Results: In total, 60 children and 60 adolescents were evaluated, 65 (54.16%) males and 55 (45.83%) females. No differences were observed between genders in groups A1 and A2 (p=0.30) and B1 and B2 (p=0.94). The highest means of the VPTm scale were observed in groups A2 and B2 (2.87 ± 2.30 and 2.13 ± 1.29) and the lowest in groups A1 and B1 (1.13 ± 1.45 and 1.20 ± 1.29), respectively. Statistical differences were observed for the mean VPTm scores between age groups A1 and A2 (p=0.004) and B1 and B2 (p=0.018). Conclusion: The level of anxiety was inversely proportional to age, so younger children were more anxious; it was also observed that children and adolescents who had never been to the dentist tended to be more anxious.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
