Dr. Rajkrishnan's Dental Clinic in Tripunithura which is well known for dental tourism in Kerala has been awarded ISO 9001-2000 certificate. The certificate was handed over to Dr. Rajkrishnan, the CEO of the clinic, by the tourism director Mr. B Suman.

In 1997, this institution came up with the concept of  "Dental Tourism". Dental treatment abroad is time consuming and expensive. Since most of the dental treatments are elective, tourists can relish the beauty of Kerala and alongside get their dental treatment done. This is the concept of Dental Tourism.
