Dentist-related factors influencing the amount of prosthodontic treatment provided

Abstract

To evaluate, using multivariate methods, the associations between indicators of the amount of prosthodontic treatment and dentist-related factors. Questionnaires were sent to a random sample of 2,059 general dentists, response rate was 76%. Two indicators of prosthodontic activity were used as dependent variables: 1) reported weekly working hours used for prosthodontics and 2) reported numbers of produced single crowns, fixed partial dentures, and removable dentures. Independent variables were 'social and demographic attributes', 'job situation' and 'attitudes of dentists'. Multiple regression analysis was used in models with continuous dependent variables and logistic regression analysis for categorical dependent variables. 'Weekly working hours used for dental care of adults' showed a strong association in all models with the dependent variable 'weekly working hours used for prosthodontics'. Male dentists provided more prosthodontic services than female dentists, even if reporting less time used for prosthodontics. Private practitioners produced more fixed prosthodontics than dentists employed in the public dental health service. Dentists in the public dental health service reported a higher production of removable dentures than private practitioners. The results indicate that factors, besides those in the rational clinical model for decision-making, e.g. gender and delivery system, play a role in the provision of prosthodontic services.
