ABSTRACT
Sexual relation is a very important part of the marital relationship. Any problem in the marital relationship affects the family and society cohesion. This study aim to determine the effect of Group sexual assertiveness training on Sexual assertiveness of Female Students. This quasi-experimental pre and posttest study was conducted on 80 married female students of Sistan and Baluchestan University (southeast of Iran), from 1 July 2018 to 30 March 2019.Students were selected and randomly allocated in the two intervention and control groups. The intervention group received group sexual assertiveness training in the 4 two-hourly sessions over a period of two weeks. The control group did not receive any training. The data were collected before and 12 weeks after the intervention by Hurlbert's sexual assertiveness questionnaire, and then were analyzed. After the implementation of group sexual assertiveness training, the mean score of sexual assertiveness significantly increased in the intervention group compared to the control group (p=0.01). It is recommended to add sexual assertive training to the pre-marriage education, especially in cultures in which women have a low level of sexual assertiveness

OBJECTIVES: One of the controversial factors in fracture resistance of endodontically treated teeth that are reconstructed with fiber posts is the diameter of these posts. The aim of this study is to evaluate the effect of three different sizes of quartz fiber post (#0.5- #2 - #3) on fracture resistance of dental root. MATERIAL AND METHOD: In this in vitro study, 30 mandibular premolars were selected, sectioned from CEJ, endodontically treated and randomly assigned to three groups (n=10). Post spaces were prepared and quartz fiber posts) D.T. Light-Post (with three different sizes (#0.5-#2 - #3) were seated respectively in three groups. All posts were cemented with Panavia F 2.0 dual cure resin bonding and cement. Composite resin cores were built up using a preformed polyester matrix. Specimens were embedded in acrylic resin blocks with a layer of elastic polyether Impergum around roots as PDL. A compressive load at a crosshead speed of 1mm/min was applied axially to the central fossa of each specimen using a Universal Testing Machine, until the occurrence of root fracture. Data were analyzed using one-way analysis of variance. RESULTS: There was no significant statistical difference in fracture resistance among three groups (P>0.05). Mean fracture load was 1010±250.95 N for group A with post #0.5 and 934.4± 295.18 N for group B with post #2 and ±1001301.42 N forgroup C with post #3. CONCLUSIONS: According to the findings, larger sizes of fiber posts do not decrease the fracture resistance of the root structure. Larger diameters have higher fracture resistance and furthermore by increasing the bonding area between post and root canal wall and core material, they can improve the unity within root structure and provide more stability for core material. Unlikelarger sizes of metal posts, fiber posts with larger diameters adhere to the root structure more efficiently. As a result, they will not reduce the fracture resistance of root...
OBJETIVOS: Fator controverso na resistência à fratura de dentes endodonticamente tratados, reconstruídos com pinos de fibra, é o diâmetro destes pinos. O objetivo deste estudo é avaliar o efeito de três diferentes tamanhos de pinos de fibras de quartzo (#0,5 #2 - #3) na resistência à fratura de raízes dentárias. MATERIAL E MÉTODO: Neste estudo in vitro, 30 pré-molares mandibulares foram selecionados, seccionados, tratados endodonticamente e designados aleatoriamente em três grupos (n=10). Condutos foram preparados e pinos de fibras de quartzo (D.T. Light Post TM) com três diferentes tamanhos (#0.5- #2 - #3) foram fixados, respectivamente em três grupos. Todos os pinos foram cimentados com cimento Panavia F 2.0. Pinos de resina foram construídos usando uma matriz pré-formada de poliéster. Os corpos de prova foram embebidos em blocos de resina acrílica com uma camada de ImpregumTM ao redor das raízes. Cargas compressivas na razão de 1 mm/min foram aplicadas axialmente na fossa central de cada corpo de prova, usando uma máquina universal de testes até a ocorrência de fratura radicular. Os dados foram submetidos à análise de variância. RESULTADOS: Não houve diferenças estatisticamente significantes na resistência à fratura entre os três grupos (P>0,05). A carga média de fratura foi 1010+-250.95 N para o grupo C, com o pino # 3. CONCLUSÕES: De acordo com os achados, tamanhos maiores de pinos de fibra não diminuem a resistência da estrutura radicular. Maiores diâmetros têm mais resistência à fratura e, além disso, pelo incremento da área de cimentação entre o pino e a parede da raiz, podem melhorar a união dentro da estrutura radicular e proporcionar mais estabilidade para o material de núcleo. Ao contrário de pinos metálicos de maior tamanho, os pinos de fibra de maior diâmetro aderem à estrutura radicular com mais eficiência. Como resultado, não reduzirão a resistência à fraturada raiz. Assim sendo, quando restaurarem-se dentes endodonticamente...
