Objectives: The aim of this study was to develop and validate a DCG assessment framework for use in local dental schools in Iran. Methods: A mixed method (qualitative and quantitative) was used in the present investigation. The study was performed in 3 steps, including: a) thorough literature review, b) focused group discussion and c) Application of validated instrument. The content validity index (CVI) and content validity ratio (CVR) were calculated for each question. The Cronbach's alpha coefficient was calculated to evaluate the internal consistency and reliability for this questionnaire. The Smart PLS software was used for calculation of Goodness of Fit (GOF) for confirmatory factorial analysis to determine construct validity of this questionnaire. Results: Initially, 140 items covering 7 DCG domains were identified after comprehensive literature review. Ten specialists participated in the expert panel, rating independently on the necessity, relevancy, simplicity and clarity of each question. Expert’s ratings were used to calculate the validity for each question. The questions with CVI lower than 0.79 and the CVR less than 0.62 were excluded. Reliability analysis was conducted by calculating intra class coefficient (ICC) and Cronbach's alpha coefficient which were 0.88 and 0.92 respectively. This shows good reliability and internal consistency of the questionnaire. Construct validity determined by computing Goodness of Fit index. The result was 0.622, which indicates a good level of construct validity. After validation process, 124 out of 140 questions left to cover the 7 domains of DCG in our newly developed and validated framework. Conclusions: The newly developed and standardized DCG framework can be used for assessment of compliance level among Iranian dental schools at the national level.
Introduction: Teeth loss and its consequences, such as mental discomfort, most often negatively affects one's health and well-being. Dental implants were introduced in an attempt to raise patients’ satisfaction and improve health and quality of life in all dimensions. Hence, this study was performed to check the impact of implantation on the oral health indices in patients who were candidates for implant treatment in Isfahan city. Material and methods: In this analytical cross-sectional study, the lifestyle quality of 73 patients who were referred to Isfahan’s Islamic Azad Dental University (Khorasgan) and its affiliated private centers, was assessed using the OIDP index before and after their implant treatment between 2019 and 2020. Also, data analysis was done using Independent t-test, Paired t-test and analysis of variance ANOVA test (α = 0.05). Results: In the current study, the most common problem and with the most effect on oral satisfaction quality were teeth lost and extractions, respectively. Majorly, the effects were evident on the eating habits (83.6%), satisfaction of communication with others (68.5%) and quality of smile (64.4%). In the questionnaire, an attenuated score of OIDP was recorded, before the implant treatment compared to that of post-treatment, which was statistically meaningful (p value < 0.05). Conclusion: According to the current study data, we can conclude that implant treatment can have a positive effect on the patients’ lifestyle quality.
