Abstract
This study identified factors that influence dentists’ decisions regarding less invasive caries removal techniques such as stepwise removal (SW) and selective removal (SE) using a marketing research technique, conjoint analysis. A survey was
sent to 1,434 dentists practicing in Iowa. Dentists were ran-domly assigned to receive a questionnaire to rate the like-lihood they would use either SW/SE in hypothetical clinical scenarios. The scenarios were carefully created by conjoint
design and included three relevant attributes: depth of lesion, hardness of carious dentin, and patient age. Descriptive and conjoint analyses were performed to assess trade-offs be-tween these attributes, using SPSS. The study revealed that
depth of lesion was the most important factor in the dentists’ decisions (49 importance value) when choosing a SW to treat a deep carious lesion, followed by hardness of carious dentin and patient age (21 importance value). For the SE group, depth of the lesion was also the predominant factor when selecting a treatment. The study also identified that a high proportion of dentists (24.9%) indicated they would never consider using SW or SE under any circumstances. Our survey showed that depth of lesion was the most important reason to select a less invasive caries removal method. The high proportion of dentists indicating they would never consider selective caries removal (SE) techniques suggests that these less invasive options are underutilized.
