RUIZ-GARCIA-DE-CHACON, Vilma Elizabeth et al. Perception of risks associated with imaging studies in users of an Oral Radiology Service in a Dental. Rev. Estomatol. Herediana [online]. 2014, vol.24, n.4, pp.239-247. ISSN 1019-4355.

Objective: Measure the perception of risks associated with imaging tests and the level of knowledge on imaging tests on users of the Oral Radiology School of Dentistry in Lima (Perú). Methods: A questionnaire for the study was developed (V Aiken: 0.97, Cronbach’s alpha: 0.70 for Risk Perception and 0.65 for level of knowledge, and CCI: 0.81). The study included 330 volunteers aged between 18 and 64 years (68.8% women), aged 45 years, mostly with a higher level of instruction and born in Lima. The largest proportion of scores for perception of risk associated with imaging and to the level of knowledge on imaging tests were intermediate level. Results: Female sex was associated with a higher level of risk perception (X2 p=0,007) and higher ages were associated with a higher level of knowledge (X2 p=0.023). Conclusions: The users of the Oral Radiology Department of the Central Clinic of the Dentistry School at the Universidad Peruana Cayetano Heredia in 2013, were mostly women over 45 years old, with a higher level of instruction, born in Lima and from neighboring districts to the institution. Perception scores of risks associated with imaging studies were in greater proportion of intermediate level. Scores on the level of knowledge about the risks were also in a higher proportion of intermediate level. Female sex is associated with higher levels of perceived risk, and also, the older age is associated with a higher level of knowledge.
