Volume 15, Issue 3 (6-2002)
Abstract

Nowadays, application of implants as a new method for replacing extracted teeth have been improved. So, many researches have been performed for improving the characteristics of implants. The aim of this study was to design and produce a desired coating in order to obtaining two goals including improvement of the corrosion behavior of metallic endodontic implant and the bone osseointegration simultaneously. Stainless steel 316L (SS), cobalt-chromium alloy (Vit) and commercial pure titanium (cpTi) were chosen as metallic substrates and hydroxyapatite coating (HAC) were performed by plasma-spraying (PS) process on three different substrates. A novel double layer Hydroxyapatite/Titanium (HA/Ti) composite coating composed of a HA top layer and a Ti under layer was prepared using PS and physical vapor deposition (PVD) process respectively on SS. Structural characterization techniques including XRD, SEM and EDX were utilized to investigate the microstructure, morpholgy and crystallinity of the coatings. Electrochemical potentiodynamic tests were performed in physiological solutions in order to determine and compare the corrosion behavior of the coated and uncoated specimens behavior as an indication of biocmpatibility. Results indicated that the cpTi possesses the highest and SS the lowest corrosion resistance (highest corrosion current density) between uncoated substrates. This trend was independent to the type of physiological environment. The HA coating decreased the corrosion current density of HA coated metallic implants but did not change that trend. HAC acted as a mechanical barrier on the metallic substrate but could not prevent the interaction between metallic substrate and environment completely. The HA/Ti composite coating improved the corrosion behavior of SS. The corrosion current density of HA/Ti coated SS decreased and was exactly similar to single HA coated cpTi in physiological solutions. The results indicated that HA/Ti composite coated SS could be used as an endodontic implant and two goals including improvement of corrosion resistance (biocompatibiiity) and bone osseointegration could be obtained simultaneously.

Abstract

Background and Aim: Dental anxiety is a common problem in pediatric dentistry and results in behaviors like fear and anger that can negatively affect dental treatments. Exposure to various dental treatments and distressful experiences are reasons for anxiety during dental treatments. The aim of this study was to evaluate effect of cognitive behavioral interventions in reduction of stress during dental procedures in children.

Materials and Methods: In this clinical trial, 42 boys and girls, undergoing dental treatments were selected from dental clinics in Tehran. Patients were assigned to cognitive-behavioral interventions, placebo and control conditions. The fear scale, anger facial scale, pain facial scale and physiologic measure of pulse beat were evaluated. One way ANOVA and Tukey test were used to analyze the results and p<0.05 was the level of significance.

Results: Results showed significant differences between cognitive-behavioral interventions, placebo and control groups regarding fear, anger, pain and pulse beat. Comparison tests revealed that cognitive-behavioral interventions were more effective in reducing fear, anger, pain and pulse beat compared to the placebo or control.

Conclusion: According to the results of this study cognitive-behavioral interventions can be used to reduce distress of children undergoing dental procedures.

Abstract

Background and Aim: It is necessary to assess health status for designing and programming about oral health behaviors. In this study the Effectiveness of Health Promotion Model in Predicting oral health among the Students of Islamic Azad University of Sabzevar was examined.

Materials and Methods: This was a descriptive-analytic, cross-sectional study. A random (stratified) sample of 250 university students in Islamic Azad university of Sabzevar, participated in the study. Appropriate instruments were designed to measure the variables of interest based on health promotion model. Reliability and validity of the instruments were examined by a panel of experts and cronbach alpha (N=30,α=0.65-0.81) respectively. The data were analyzed by SPSS 11.5 Statistical Software using Spearman Coefficient, Path analysis based on regression and ANOVA.

Results: The mean of oral health behaviors among students was moderate (19.17±3.91 out of total 36).Statistically significant differences were found in oral health behaviors and the model variables by parent education (P<0.05). The results showed that the model variables were related to oral health behaviors of the students (P<0.05).Self-efficacy,interpersonal influences,positive emotion, perceived barriers and commitment to plan of action as variables of HPM model explained 29% of oral health behaviors among subjects within which self-efficacy was the strongest predictor)β=0.252).

Conclusion: Although the mean of oral health behaviors was moderate among the subjects, but it should be promoted because of their great importance on the individuals' health. It was concluded that the Health Promotion Model may be used as a framework for planning intervention programs in an attempt to improve the oral health behaviors of the university students.

Abstract

  Background and Aims: Successful pediatric dentistry depends on the dentist's technical skills, as well as his/her ability to acquire and maintain a child's cooperation. The correction of dentist’ performance in this area affects the view of parents and increases the quality of dental services. The aim of this study was to evaluate the attitudes of general dentists toward behavior guidance techniques in Isfahan.

  Materials and Methods: In this descriptive- analytic cross-sectional study, 100 general dentists of Isfahan city were selected with simple random sampling technique. They were asked to complete the questionnaire inquiring their attitude toward four different behavioral management techniques . An appropriate question about each of the methods was proposed by the authors, along with demographic characteristics including: gender, age, university, year of graduation, work experience, the mean number of pediatric patients referred in one month was provided in the form of a questionnaire. To evaluate the attitude of dentists to the questionnaire, the score from 1 to 5 was given to each item and the total score was considered. Higher score indicated more positive attitude of dentist. Data were analyzed using T-test, Pearsons correlation and one-way ANOVA (P<0.05).

  Results: The mean scores for dental behavioral management techniques were positive reinforcement (4.2±2.7), general anesthesia (3.5±4.4), N2O sedation (3.4±4.4) and pharmacologic sedation (3.2±2.7), respectively. There were no significant differences between the mean score of dentist attitude and age, gender, clinical experience and the number of pediatric patient (P>0.05).

  Conclusion: General dentists’ attitudes towards different behavior management techniques were associated with age, gender, clinical experience and the number of pediatric patient. General dentists’ tend was more towards non-drug behavior control methods such as positive reinforcement.

In interventional group 96.2% of and in the control group 90.8% of children had good and very good behavior but the difference was not significant (P=0.11).

  Conclusion: Although the educational pamphlet was effective on the separation of child from mother. No significant difference in behavior of 3-7 year-old children between interventional and control group was found.


Investigating the relationship between stress and oral health-related behaviors changes in final year of high school students prior to university entrance exam
Mostafa Motallebi, Maryam Sadeghipour, Nika Mehrnia, Mohammad Behnaz, Nahid Mohammadnia,
Volume 35, Issue 0 (5-2022)
Abstract
Background and Aims: Today, academic stress and subsequent test anxiety is one of the most important problems for the last year of high school students. In addition to systemic effects, stress can affect the level of oral health by disrupting oral health behaviors. The aim of this study was to investigate the relationship between stress and variables related to oral health in the final year of high school students prior to University entrance exam.
Materials and Methods: In this descriptive-analytical study, the level of stress and variables related to oral health in 180 students of the final year of high school in Tehran, in three time periods during the academic year 2018-2019, were measured by a questionnaire and one clinical examination. Data were analyzed by Friedman, Bonferroni and Generalized Estimating Equations using SPSS software.
Results: As the exam approaches, some variables related to the oral health, such as toothbrush usage pattern, daily sleep, fast food frequency, and sweet snack consumption, changed (P<0.05). Daily sleep changes were significantly associated with the stress changes (P=0.022). According to the results of the Repeated Measures Analysis, significant changes were observed between the average score of the "Cognitive Error" aspect of three times (P<0.001). Also, according to the results of the Bonferroni Test, significant changes related to the difference in the average score of "cognitive error" 6 months and 3 months before the entrance exam (P<0.001), 6 months and 1 month before the entrance exam (P<0.001), and 3 months and 1 month before the entrance exam (P<0.001) were observed. In all three cases, as the time of the entrance exam approaches, the score of "cognitive error" had decreased significantly. Considering that the lower score in this index indicates a higher level of test anxiety, the closer we get to the entrance exam, the higher the level of test anxiety in the "cognitive error" dimension
Conclusion: The academic stress of the national university entrance exam can affect some oral health variables such as daily sleep, however, it is not related to other variables.
