Objectives
The aim of this study was to examine the influence of experience and gender on the radiographic detection of proximal caries lesions and on therapeutic decisions.
Materials and methods
A survey of 220 examiners (students and employees at three universities and dentists in the field) was taken using a standardized written questionnaire concerning radiographic diagnosis and therapy planning. An expert opinion of four dentists was determined as radiographic reference. A mixed effect logistic regression model was used for statistical evaluation and the odds ratio and p values were calculated (α = 0.05).
Results
Examiners with experience had an almost four times greater chance of a correct assessment, if proximal caries lesion was present or not, than examiners with low experience (OR 3.7 (95% CI 2.4–5.8)). No gender-specific differences were discovered (OR women vs. men 0.9 (95% CI 0.6–1.4)). There was a relationship between the severity of the burnout effect on the x-ray and false positive caries diagnosis. Overall, 43% of respondents would plan invasive treatment in the enamel on a patient at low risk of caries and 78% on a high-risk patient. The results showed that the more experienced practitioners would be more likely to postpone restorative therapy on proximal caries until the lesion reached a later stage.
Conclusions
The results of this study suggest that examiner’s experience influences the radiographic diagnosis of proximal lesions. No gender-specific differences could be found.
Clinical relevance
Examiner’s professional experience is an important factor when radiography is included for detection and treatment planning of proximal lesions.
