ABSTRACT
Objectives: Oral cancer is a global health problem; however, many dentists lack the necessary skills, knowledge and capacity to diagnose oral cancers early. This study aimed to examine the validity and reliability of a Persian short-form version of a standardised questionnaire to assess dentists' knowledge, practice and attitudes towards oral cancer
Methods: This cross-sectional analytical study was carried out in May 2015 in Tehran, Iran. An original 39-item English-language questionnaire developed by Yellowitz et al. was translated into Persian using forward and backward translation methods. A total of 15 dental professionals were asked to assess the questionnaire for content validity. Based on their feedback, a 20-item short-form version was prepared, including six demographic, six knowledge, four attitude and four practice items. The translated short-form questionnaire was subsequently distributed to 973 general dental practitioners attending a dental conference in Tehran. Internal consistency and reliability were assessed with Cronbach's alpha coefficient and item-total correlation calculations
Results: A total of 13 professionals and 313 general dentists participated in the study [response rates: 86.7% and 32.2%, respectively]. After the elimination of six items [two knowledge, two attitude and two practice items], the validity and reliability of the questionnaire was confirmed
Conclusion: The final Persian 14-item version of the questionnaire had acceptable validity and internal consistency. These results indicate that researchers can use this translated short-form version to evaluate oral cancer knowledge, attitudes and practices among Persian-speaking dentists; this will allow for a comparison of data between different populations
ABSTRACT
Objectives: recognising causes of stress can help prevent associated adverse effects. This study aimed to investigate causes of occupational stress and coping behaviours among general dentists in Iran
Methods: this cross-sectional study was carried out from April to December 2014. A modified version of the Occupational Stress Indicator questionnaire was used to assess causes of stress and coping behaviours among 142 general dentists in Kerman, Iran
Results: a total of 93 dentists participated in the study [response rate: 65.5%]. Of these, 58.9% reported often being stressed. The mean general stress score was 63.33 +/- 19.99. The most common causes of stress were maintaining high levels of concentration while working [65.6%], time pressures [64.5%], concern over their ability to deliver dental services in future [60.2%] and rising costs [59.1%]. No significant relationships between stress and gender, age, workplace or working hours per week were noted [P >0.05]. However, there was a significant correlation between general stress scores and years of job experience [P = 0.05] and number of patients treated daily [P = 0.03]. The most common methods for coping with stress were resting [71.0%], sports [45.2%] and entertainment [43.0%]. Most dentists felt that stress management courses could help to reduce stress [89.7%]
Conclusion: general dentists in Kerman were subject to many sources of stress in their workplaces, with significant relationships between stress scores and years of work experience and number of patients treated daily. Dentists should be encouraged to participate in stress management courses to help alleviate stress
ABSTRACT
The objective of this study was to assess the knowledge and use of evidence-based dentistry [EBD] among Iranian dentists. A cross-sectional survey was conducted by means of a questionnaire among dentists attending the 52[nd] National Annual Congress of the Iranian Dental Association in Tehran in April 2012. The questions covered the participants' level of knowledge and use of EBD. The mean knowledge score of the 310 respondents was 3.66 +/- +/- 1.19 out of a maximum of 5. The majority of the dentists had little [56.1%] or no [20.7%] knowledge of EBD. The main reported barrier to the use of EBD was lack of time [44.1% of respondents] with 42.8% of dentists using the Internet less than one hour per week. EBD was not a familiar concept to these Iranian dentists; the majority of them preferred consultation with colleagues over seeking evidence from electronic databases
ABSTRACT
There is scant information regarding the multifactorial aetiology of denture stomatitis [DS] in the world and, despite its frequency, associated factors are not completely understood. The aim of this study was to investigate the risk factors that may be associated with this lesion. A total of 70 edentulous patients, all wearing removable dentures, were divided into two groups. The test group comprised 43 patients with DS and the control group comprised 27 subjects with clinically healthy palatal mucosa. A thorough history-taking and physical examination were carried out; the subjects also answered a questionnaire. The serum level of vitamin A for each subject was assayed from a blood sample taken after the examination. This study showed a significant relationship between the incidence of DS and three major factors: denture age [in terms of years], the practitioner manufacturing the dentures [general dental practitioner versus dental hygienist], and the nightlong wearing of dentures. Also, the vitamin A serum level was low in 94.29% of all subjects [cases and controls]. Although many predisposing conditions were related to this situation, the most important risk factor was the continuous use of the dentures
