Craig Barrington, DDS, graduated summa cum laude in 1996 from the School of Dentistry at the University of Texas Health Science Center at San Antonio. Microscopes and histology have always been an interest of his, but the first time he looked at a transparent human tooth, he knew that this would be a lifelong focus of his research. To this end, Dr Barrington has made it his mission to understand every diaphanization method that he has come across. Dr Barrington holds a patent in histology and multiple copyrights. He maintains a private practice in Waxahachie, Texas.
