The purpose of this study is to model two variables of essential importance to the analysis of the financial burden of certain dental diseases. These are the patients' preferences for the treatment of a broken molar with treated root canals and their willingness to pay for the selected option.The tools used to identify patients' preferences and their willingness to pay are based on Vernazza's interview [1] used in his doctoral thesis entitled "The monetary value of oral health: willingness to pay for treatment and prevention". Vernazza used an interview for his study. We compiled a direct anonymous questionnaire containing Vernazza's questions relating to:
AbstractBackground. This study is an attempt to model patient's preferences for molar treatment and the willingness to pay (WTP) for a chosen health alternative. The results from modeling could be used as a basis for making more efficient decisions from both medical and economic point of view. The study is based on questions from Vernazza's interview. Objectives. The first purpose of present study is to be explored and established the most wished preferences from previously stated ones and closely related with patient choice's WTP. The second aim is to be built and interpreter models of the consumer choices and its WTP. Material and Methods. The sample consisted of 111 adult patients who visited for treatment different dental cabinets located in Plovdiv, Bulgaria. The study was conducted using the method of direct anonymous questionnaire containing questions on the choice of health alternative and the WTP for it; demographic, social and economic characteristics of respondents; history and severity of dental diseases, and frequency of dental visits. The study used two types of regression models: binominal logit of patient's choice and negative binominal of the WTP for a crown that led to statistically credible results. Results. The main predictor for the willingness to pay turned out to be the total monthly income of the household. Other factors, such as frequency of visits to the dentist, age or employment status of respondents can not be used to explain the changes in their WTP. Conclusions. The economical factors especially the WTP and the household income stay essential. That empirically confirmed fact puts the economic welfare and it variables as predictors with critical meaning in health market researches. The second important outline is that we found a similarity in results with Vernazza's study. That fact supports a reliability of the applied instrument (Dent. Med. Probl. 2016, 53, 1, 41-49).
