Introduction: The use of different models play a significant role in health education and its promotion. Therefore, the present study aims to investigate the effect of the Theory of Planned Behavior (TPB) on early dental decay in elementary students. Methods: This study was a single-blinded, cluster randomized controlled trial, in which 470 elementary students in the fourth, fifth and sixth grades in Saveh, Iran were participated. A demographic questionnaire and a 5-item questionnaire consisting of questions on awareness, attitude, practice, tooth brushing, diet and referring to dentist, were used to data collection. The samples of the intervention (n=234) and control (n=236) groups filled out the questionnaires before intervention (pre-test), immediately after intervention and one month after intervention. The educational intervention based on the TPB was held in three 45-minute sessions. Finally, the data were analyzed, using the SPSS version 13. For analyzing, the Independent t-test, Chi-square, and repeated measures ANOVA were used. Results: This study showed that there is a significant difference in the mean scores obtained from knowledge, attitude, subjective norm, perceived behavioral control, behavioral intention and behavior among students in the experimental group (immediately after and one month after the intervention) and students in the control group. Conclusion: The results of this study showed that using of TPB, as a framework for providing behavior-led training, can be effective in promoting oral and dental health of students. Nurses as an important member of the treatment team can use the results of this study in school health programs.

Background: The concept of dying with dignity is being discussed in various fields, including psychology, sociology, medicine, and nursing, with different definitions available for this concept. However, few studies investigated the concept of end-of-life nursing care, which plays an important role in the implementation of the concept. This concept can also affect people’s perception, attitude, and behavior toward practicing dignified death in health-care centers. The current study aimed to clarify, understand, and further recognize the concept of death with dignity in end-of-life nursing care. Materials and Methods: Rodgers’ evolutionary concept analysis was used to clarify the concept of death with dignity in end-of-life nursing care. MEDLINE, BLACKWELL, PROQUEST, Science Direct, and CINAHL databases and national databases of SID and Iran Medex were systematically searched to identify relevant studies using various combinations of the following keywords: “dignity,” “dignified death,” “dying with dignity,” and “dignifying death” in combination with “end-of-life care.” All articles with the above-mentioned terms in their title, abstract, or keywords and published in English from 2006 to 2020 were included. A total of 21 articles were finally identified for review. Results: Characteristics of dying with dignity were categorized into two dimensions of human dignity and holistic care. The antecedents included professional and organizational factors, and outcomes included good death and career promotion. Conclusions: This study demonstrated that end-of-life nursing care is an important dimension of clinical nursing that plays a unique role in admission and facilitating the process of dying and, eventually, dying with dignity.
