62 per hour in 2007 to $41.55 per hour in 2010, an increase of $1.93 per hour. The mean nominal dental assistant hourly wage increased from $19.42 in 2007 to $21.45 in 2010, an increase of $2.03 per hour. After accounting for increases in cost of living using constant 2010 dollars, changes in these staff wages were an increase of $1.03 for dental assistants and a decline of $0.13 in the mean wages

of dental hygienists. While practice expense reflects the cost to the practice to use various resources ABT-263 solubility dmso to produce and render prosthodontic care, gross revenues reflect the gross economic returns to the practice and are the primary source used to reimburse for the use of all economic resources. Figure 12 contains responses about the percentage of respondents reporting by categories of gross billings. In 2007 and 2010, more than 55% of respondents reported their Belinostat molecular weight gross billings were less than $1 million dollars. Reporting more than $1.5 million included 22% of respondents in 2007 and 25% of respondents in 2010. The average gross billings per prosthodontist was $721,970, down from the $805,670 in 2007 as shown in Table 4. Table 4 contains the average nominal gross receipts calculated per practice, per prosthodontist, per practice owner, and per solo prosthodontist. Gross receipts are the amount of gross billings reported by respondents as being actually collected. In 2007, the average nominal

gross receipts were $1,072,110 per practice and $1,063,110 in 2010 (a decrease of 0.8%). The average amount of nominal gross receipts per prosthodontist and per solo dentist declined from 2007 to 2010. The mean gross receipts per owner prosthodontist increased from $925,840 in 2007 to $944,210 in 2010, an increase of 1.9% for the period. Net income of private practicing prosthodontists was defined in the survey as income received after practice expenses and business taxes, including commissions, bonuses, and/or dividends. The results (Table 5) MCE indicate the decline

in the mean net income reported by respondents from 2007 to 2010 for three groups: (1) all prosthodontists, (2) owner prosthodontists, and (3) solo prosthodontists. The mean net earnings are the highest for the prosthodontist owner group and lowest for the solo prosthodontist. The reported mean earnings in 2010 were lower than the mean net incomes of 2007 for all three groups, as shown in Table 5. The average annual declines in the nominal mean net incomes were 5.1% among all prosthodontists, 2.6% among prosthodontist practice owners, and 6.8% among all solo prosthodontists. In addition to the net income from the private practice of prosthodontists, income can also be earned from other sources, such as consulting, teaching, hospital care, or other activities such that total net income of prosthodontists is larger than the net income from practice alone.
