There are many factors that affect the hours worked by various professions. The literature discusses some of these factors in professions such as management and various fields of medicine. However, no information has been gathered on factors that affect the practice of dentists. A survey was disseminated to all Iowa dentists inquiring about various factors that may affect the number of hours they spend at work. The survey inquired about demographics, educational indebtedness, caregiving responsibilities of both children and dependent adults, contribution to household income, relationship status, domestic responsibilities, busyness and type of practice. The data was collected and analyzed. It was hypothesized that there was no difference in the number of hours worked between male and female Iowa dentists and there was no difference in the number of hours worked between female Iowa dentists with minor children (18 years old or younger) and female dentists without minor children. When hypotheses were statistically analyzed, the data showed there was no difference between male and female dentists' working hours in the bivariate analysis. In the multiple logistic regression model, while controlling for various factors such as age and busyness, gender was statistically significant in the number of hours worked. When evaluating the hours worked between female dentists with and without minors, there was a statistically significant difference in the number of hours worked between women with minor children and women without minors. However, in the multiple logistic regression model, presence of minors was not statistically significant. This lack of statistical significance is likely attributed to the small sample size of women dentists. As such, there was not enough power to have more than 2 variables and minor children was not included. The data suggests that young male dentists, who are responsible for 61% or more of their household income and are solo practitioners are the most likely to work full-time (32+ hours/week).
