RESUMO
Statement of the Problem: Denture stomatitis is the common form of oral candidiasis, which is seen in the form of diffused inflammation in the areas covered by dentures. Many primary studies report the prevalence of denture stomatitis and candida albicans among patients in the Iranian population; therefore, using meta-analysis is valuable for health policy makers
Purpose: The purpose of the present study is to determine the prevalence of denture stomatitis and candida albicans in Iran
Materials and Method: Using relevant keywords, national and international databases were searched. After limiting the search strategy and deleting the duplicates, the remaining papers were screened by examining the title and abstract. In order to increase the sensitivity of search reference lists of papers were examined. Finally the index of heterogeneity between studies was defined using Cochran test [Q] and Isquared [I2]. According to heterogeneity, the random effects model was used to estimate the prevalence of denture stomatitis and candida albicans in Iran
Result: The prevalence of denture stomatitis in 12 studies, and the prevalence of candida albicans in patients with denture stomatitis have been reported in 6 studies. The number of sample under investigated and its age range among primary studies included meta- analysis was 2271 individuals and 32.7 till 87.5 years respectively. The prevalence of denture stomatitis in preliminary studies imported to a meta-analysis varied from 1.9% to 54.6%, and its rate in Iran using the meta-analysis was estimated 28.9 % [CI 95%: 18.2-39.6]. Also the overall prevalence of candida albicans in patients with denture stomatitis in Iran was estimated 60.6% [CI 95%:50.1-71.2]
Conclusion: This study showed that the prevalence of denture stomatitis and candida albicans among patient infected denture stomatitis is relatively significant in Iran
RESUMO
Statement of the Problem: The first step towards appropriately planning orthodontic treatment and prevention services is to understand the needs and demands of the target population. However, this is ignored in most developing countries
Purpose: This study aims to evaluate the attitudes of patients in Fars province towards travelling to the provincial capital [Shiraz] to receive orthodontic treatments
Materials and Method: This cross-sectional study randomly selected 420 patients referring to two public and four private orthodontic centers in Shiraz, coming from other regions of Fars province. The patients were interviewed about their demographic status, residing area and the reasons of deciding to receive orthodontic treatment in Shiraz. Data were analyzed by SPSS software, using Chi-square and ANOVA statistical tests
Results: The response rate was 96% [N=403]. Near half of the patients [176; 43.7%] lived 100-200km, and 80 [19.9%] patients lived farther than 200km from Shiraz. Having no orthodontist [54.8%] and no dentist providing orthodontic treatment [39.2%] in their region were the most important factors bringing the patients to provincial capital for orthodontic treatments. High costs of treatment in their home county and hoping to receive treatment of higher quality were the other important motives for lower and higher socio-economic backgrounds, respectively. Friends'/relatives' recommendation was a more important factor in patients using public clinics for choosing their therapist, while referral from dentists was more important for patients going to private clinics. The patients who lived in counties farther than 200km from Shiraz were more concerned about quality of treatment results than those who lived closer [p= 0.010]
Conclusion: A multifactorial approach is needed to provide the desired orthodontic services for people in Fars province so that they would not need to travel to the capital for such treatments
RESUMO
Statement of the Problem: Exposure to patients' blood and body fluids would prone the dental students to the risk of blood borne infections. Several studies have shown a high prevalence of these exposures in dental settings particularly in developing countries. However, few studies have evaluated the epidemiology of these exposures in dental students in Iran
Purpose: To assess the epidemiology of occupational exposures among dental students and consequently designing the appropriate interventions in order to prevent these exposures
Materials and Method: In this cross-sectional study performed during March to June 2011, all 191 Shiraz clinical dental students were asked to complete a self-administered questionnaire. This questionnaire included demographic information and experience of sharp injuries and mucocutaneous contaminations. Chi square and t-test were employed to evaluate the risk factors of exposure
Results: 80%of the participants were exposed to the patients' blood or body fluids during their clinical course. No association was found between the exposure and demographic factors. Injection needle and recapping were the most common causes of these injuries. The most common sites that were injured and caused mucocutaneous contamination were finger and face, respectively. The most frequent activity causing contamination was using high-speed rotary instruments. Only 6.4% of the exposures had been reported to the related authorities and the remains were underreported
Conclusion: Blood and body fluid exposure in dental setting is common and a lot of them are not reported. To reduce the hazards of these exposures, infection control authorities should design interventions especially for mentioned high-risk conditions. They should change dental students' behavior especially regarding not recapping injection needles and using eyewear. Dental schools seem to need a management center and a standard protocol for following up the exposures
RESUMO
Statement of the Problem: No published literature was found studying the people's reasons on why to choose or not to choose a dental care setting in south Iran, while understanding their attitude towards choosing their dental care center is consequential for planning a successful oral health care service system
Purpose: To determine the factors affecting how people of the city of Shiraz choose their dental health services
Materials and Method: A cross-sectional analytic study was designed. A self-administered questionnaire was produced, tested and then distributed among 570 multistage randomly selected parents of schoolchildren of the city of Shiraz. Independent t-test, paired t-test and Spearman correlation were used to analyze the factors influencing participants in choosing clinics for their esthetic and non-esthetic dental treatments
Results: 400 questionnaires were complete and analyzed. The recommendation from others was found to be the most encouraging factor to choose a dentist or a dental clinic. More importance was reported for various factors affecting participants' choice of dental clinic when seeking non-esthetic treatments, while recommendation and reputation of dentist/dental clinic played a vital role in esthetic treatments. The cost was more important for respondents living in more deprived districts [p= 0.05], for unemployed group [p< 0.001] and for those with less education [p< 0.001]
Conclusion: Factors affecting people's choice for dental care proved to be highly complicated. Recommendation was found playing an important role. Dental patients consider various factors when looking for non-esthetic treatment but would go for the best possible when seeking esthetic treatments. Findings of this study indicate that patients' choice and utilization of dental service can be improved if dental clinics provide high quality of dental care with reasonable fees
