Resumo Introdução Atualmente, diferentes escalas têm sido utilizadas para medir a dor no contexto clínico, especialmente na prática odontológica. Objetivo O objetivo deste estudo foi comparar as escalas de dor comumente utilizadas em pesquisas clínicas e na prática clínica odontológica, identificando as mais fáceis de serem compreendidas pelos pacientes com hipersensibilidade dentinária cervical. Método Setenta e quatro pacientes com hipersensibilidade dentinária cervical foram estimulados por um teste térmico para avaliação do dente sensível, seguido pela aplicação de diferentes escalas para avaliação de dor (Escala Visual Analógica, Faces de Dor, Escala Numérica e Escala Verbal) e de um questionário complementar para avaliar a percepção do paciente em relação à facilidade de compreensão das escalas. Os resultados foram submetidos aos testes de correlação de Wilcoxon, Spearman e Qui-Quadrado. Resultados Uma forte correlação positiva foi encontrada entre as quatro escalas avaliadas (r = 0,798 a 0,960; p < 0,001). De acordo com os pacientes, a escala de mais fácil compreensão foi a Escala Verbal (52,7%). Conclusão As escalas para mensuração da dor fornecem informações semelhantes sobre a dor relatada na hipersensibilidade dentinária cervical. A afinidade do paciente pela escala de dor pode direcionar a escolha da escala a ser utilizada na prática clínica odontológica nos diversos níveis de atenção à saúde.

Abstract Background Currently, different pain scales are used extensively to measure clinical pain, especially in dental practice. Objective This study aims to compare pain scales used in clinical research and dental practice, identifying the easiest to understand by patients with Cervical Dentin Hypersensitivity. Method Seventy-four patients with Cervical Dentin Hypersensitivity were stimulated by a thermic test of the sensitive tooth, followed by application of different pain measurement scales (Visual Analogue Scale, Faces Pain Scales, Numeric Rating Scale, and Verbal Rating Scale) and by a questionnaire to evaluate the patient's perception regarding the ease of understanding scales. The statistic tests used were the Wilcoxon, Spearman correlation, and Chi-Square tests. Results The results founded a strong positive correlation between the scales (r = 0.798 to 0.960 p <0.001). The was easiest scale to understand according to the patients was the Verbal Rating Scale (52.7%). Conclusion The pain measurement scales evaluated provide similar information about pain reported in the Cervical Dentin Hypersensitivity allowing the comparison between studies that used them to measure pain. The affinity of the patient with the pain scale can guide the clinical dental practice in the different levels of health care.

Abstract Objective: To identify the need for restorative treatment in 12-year-old Brazilian schoolchildren with dental trauma and its association with clinical and socioeconomic factors. Material and Methods: A cross-sectional population-based study was carried out with sample composed of 588 12-year-old students from the city of Diamantina, Minas Gerais, Brazil. Data were collected from August to November 2016 through clinical examination, adopting the Andreasen classification and semi-structured questionnaire to verify the etiology and location of the accident that resulted in dental trauma. Statistical analysis included the frequency distribution and bi and multivariate analysis, with 5% significance level. Results: The presence of 219 traumatized teeth in 176 students was observed (29.9%). The main lesion was enamel fracture (41.4%), followed by enamel and dentin fracture (39.4%). The presence of restorative treatment was observed only in 11.5% of students. Fall (43.5%) was the most frequent etiology, followed by accidents on the streets (35.8%). Need for treatment was present in 53.4% of adolescents. Statistically significant association between males (p=0.010), severe overjet (p<0.0001) and inadequate lip protection (p<0.0001) and presence of dental trauma was observed. Maternal schooling over 8 years of study was statistically associated with need for restorative treatment (OR = 2.047; CI: 1.099-3.813; p=0.023). Conclusion: Prevalence of dental trauma, need for restorative treatment and number of adolescents with no access to restorative treatment in this study were high, point out that the health system is unable to satisfactorily prevent dental trauma and absorb all dental treatment demand resulting from dental trauma.

ABSTRACT Flowers of species of Senna are very morphologically diverse, however, nothing has been reported regarding variation in the presence of a unicarpellate gynoecium, which is characteristic of the group. This study reports the occurrence of a bicarpellate gynoecium in two enantiostylous species of Senna in an area of dry forest (Caatinga) in NE Brazil. Observations of floral morphology and estimates of the proportions of floral morphs in the populations were performed. The species produce three floral types: left (L), right (R) and bicarpellate (B). The proportion of these floral morphs were similar in the populations of Senna macranthera var. micans, but the number of B flowers in populations of S. trachypus was lower than that recorded for L and R flowers. The occurrence of this morphological variation may be related to enhancing pollen capture in both species; in S. trachypus, this variation may also be related to reducing florivory by caterpillars that were observed eating sexual elements of the flowers.

RB99395 cultivar was developed by the Sugarcane Breeding Program at the Federal University of Alagoas, which is part of RIDESA. In 1999, seeds were obtained from crosses between RB867515 cultivar and pollen from an unknown genotype in "Serra do Ouro" Crossing Station. The process of selection and experimentation was carried out in three Research Stations of Alagoas. RB99395 cultivar was released in Alagoas in May 2010, and has a high content of sucrose throughout the harvest period. Planting is recommended in fertile soils and in environments with no water deficiency, a condition which results in high agricultural yields. It is tolerant most diseases that occur in Northeast, Brazil.

Introdução: O objetivo do presente estudo foi determinar a prevalência de traumatismo dentário na dentição permanente em escolares de 12 anos de idade e sua associação com fatores demográficos (gênero e condição socioeconômica) e clínicos (sobressaliência acentuada e proteção labial).Metodologia: Um estudo transversal foi realizado em uma amostra representativa de 638 escolares. Dados foram coletados por exame clínico e questionário autoaplicável. Foram realizadas análises descritivas, seguidas do teste qui-quadrado e modelo de regressão de Poisson para determinar associações.Resultados: A prevalência de traumatismo dentário foi de 34,9%. Queda foi o principal fator etiológico (49,7%). Os resultados da regressão logística de Poisson revelaram que o aumento do overjet (> 5 mm) se manteve associado aos traumatismos dentários de forma independente das demais variáveis [PR = 1.50 (95% CI: 1.41 to 1.61); p = 0.003].Conclusão: Associação estatisticamente significativa foi observada entre aumento do overjet e presença de traumatismo dentário. Não foi observada associação estatística entre os traumatismos dentários e a condição socioeconômica. Os resultados encontrados sugerem a necessidade de estratégias de prevenção e correção ortodôntica na dentição permanente.

The scope of this study was to determine the prevalence of trauma in the permanent dentition of 12-year-old schoolchildren and assess associations with demographic factors such as gender and socioeconomic status and overjet and lip coverage clinical factors. A cross-sectional analysis was conducted using a representative sample of 638 students. Data were gathered by means of clinical examinations and self-administered questionnaires. Descriptive analysis was performed, followed by the use of the chi-square test and Poisson logistic regression model for the determination of significant associations. The prevalence of traumatic dental injury was 34.9%. Falls constituted the main etiological factor (49.7%), and occurred in the home (48.2%). The results of the Poisson regression analysis revealed that accentuated overjet (> 5 mm) remained associated with traumatic dental injury irrespective of the other variables [PR = 1.50 (95% CI: 1.41 to 1.61); p = 0.003]. Moreover, a statistically significant association was found between accentuated overjet and dental trauma. No significant associations were found between TDI and socioeconomic status. These findings highlight the need for prevention strategies and orthodontic correction at the onset of the permanent dentition.
