Knowledge of Correct Prescription of Radiographs among Dentists in Yazd, Iran

Attitude and awareness of general dental practitioners toward radiation hazards and safety

AIM AND OBJECTIVE

The aim and objective is to evaluate the level of awareness and attitude about radiation hazards and safety practices among general dental practitioners in Trivandrum District, Kerala, India.

MATERIALS AND METHODS

A questionnaire-based cross-sectional study was conducted among 300 general dental practitioners in Trivandrum District, Kerala, India. Postanswering the questions, a handout regarding radiation safety and related preventive measures was distributed to encourage radiation understanding and protection.

STATISTICAL ANALYSIS

Statistical analysis were done by assessing the results using Chi-square statistical test, t-test, and other software (Microsoft excel + SPSS 20.0 trail version).

RESULTS

Among 300 general practitioners (247 females and 53 males), 80.3% of the practitioners were found to have a separate section for radiographic examination in their clinics. Intraoral radiographic machines were found to be the most commonly (63.3%) used radiographic equipment while osteoprotegerin was the least (2%). Regarding the practitioner's safety measures, only 11.7% of them were following all the necessary steps while 6.7% clinicians were not using any safety measure in their clinic, and with respect to patient safety, only 9.7% of practitioners were following the protocol.

CONCLUSION

The level of awareness of practitioners regarding radiation hazards and safety was found to be acceptable. However, implementation of their knowledge with respect to patient and personnel safety was found wanting. Insisting that they follow the protocols and take necessary safety measures by means of continuing medical education programs, pamphlets, articles, and workshops is strongly recommended.

Imaging More Imagining less: An Insight into Knowledge, Attitude and Practice Regarding Radiation Risk on Pregnant Women among Dentists of Ghaziabad - A Cross Sectional Study

INTRODUCTION

The safety of diagnostic imaging during pregnancy is an important aspect for all clinicians. Pregnant women often do not receive proper dental care as the dentists are not aware of low diagnostic radiation doses involved in dental radiation.

AIM

To assess awareness of radiation risks on pregnant women among dentists of Ghaziabad city.

MATERIALS AND METHODS

A total of 268 practicing dentists in Ghaziabad were selected for a questionnaire based cross-sectional study. Data consisted of 18 questions which assessed the knowledge, attitude and practice of dental professionals regarding radiation risks on pregnant women. The questionnaire was distributed and collected personally by the principal investigator. Data was analyzed by Mann Whitney U test and chi-square test. The level of significance was set at p ≤ 0.05.

RESULTS

The results showed that the dentists who had attended continuing dental education program had increased level of knowledge regarding radiation effects among pregnant women as compared to the dentists who had not attended continuing dental education programs (p<0.05). Among them who had attended continuing dental education programs 93.3% were aware of the safe dose of radiation and 62% were aware of threshold radiation doses of pregnancy termination. On the contrary there was no significant difference in the knowledge, attitude and practice scores regarding radiation risks on pregnant women based on their academic qualification (p≥0.05).

CONCLUSION

The level of knowledge among dentists was found to be satisfactory, this outcome shows that continuing dental education regarding radiation protection principles and its risks on pregnant women is required to ensure maximum safety both for clinician as well as pregnant women.

Medical students' knowledge of indications for imaging modalities and cost analysis of incorrect requests, shiraz, iran 2011-2012

Medical imaging has a remarkable role in the practice of clinical medicine. This study intends to evaluate the knowledge of indications of five common medical imaging modalities and estimation of the imposed cost of their non-indicated requests among medical students who attend Shiraz University of Medical Sciences, Shiraz, Iran. We conducted across-sectional survey using a self-administered questionnaire to assess the knowledge of indications of a number of medical imaging modalities among 270 medical students during their externship or internship periods. Knowledge scoring was performed according to a descriptive international grade conversion (fail to excellent) using Iranian academic grading (0 to 20). In addition, we estimated the cost for incorrect selection of those modalities according to public and private tariffs in US dollars. The participation and response rate was 200/270 (74%). The mean knowledge score was fair for all modalities. Similar scores were excellent for X-ray, acceptable for Doppler ultrasonography, and fair for ultrasonography, CT scan and MRI. The total cost for non-indicated requests of those modalities equaled $104303 (public tariff) and $205581 (private tariff). Medical students at Shiraz University of Medical Sciences lacked favorable knowledge about indications for common medical imaging modalities. The results of this study have shown a significant cost for non-indicated requests of medical imaging. Of note, the present radiology curriculum is in need of a major revision with regards to evidence-based radiology and health economy concerns.
