Weekly autoclave testing can be performed for less than $400 annually, according to the website of the Autoclave Testing Services of Pearl River, New York.
Autoclaves typically can be purchased for $1,000 to $8,000, depending on their size and features. And an average dental practice can expect to pay more than $40,000 a year in equipment, tools and supplies alone, according to several dental organizations.
Attempts to reach Harrington have been unsuccessful. No one answered the door Thursday at his Oklahoma home, which property records show is worth more than $1 million. His practice a few miles away, in a tony section of Tulsa where plastic surgeons operate and locals congregate at bistros and stores such as Saks Fifth Avenue, has a fair-market value of around $851,000.
Property and tax records show Harrington owns another residence in Carefree, Ariz., in an area of upscale homes tucked into in the boulder-strewn mountains north of Phoenix.
Nobody was at home Saturday at the low-slung, 1950s-style vacation home, across from the Boulders Resort. Neighbors said they had seen a lot of activity at the home in recent weeks.
Harrington's malpractice lawyer, Jim Secrest II, did not respond to phone messages left Thursday or Friday. A message at Harrington's Tulsa office said it was closed and an answering service referred callers to the Tulsa Health Department.
Suzy Horton, an old friend of Harrington's, said she can't believe the allegations about the man who removed two of her teeth in the early '90s. Horton's ex-husband sold Harrington his home in Carefree — a home where she once lived.
"I've been to dentists my whole life, so I know what a professional office looks like," Horton, who now lives in Phoenix, said in a telephone interview. "His was just as professional as anybody."
Horton hasn't seen Harrington in years, but she said he has sent her a Christmas card and wreath every year since her 1999 divorce.
"It was a long time ago, so I suppose anything can change, but the kind of person they're portraying in the news is not the kind of person who sends you a Christmas" card, she said.
