In two occasions, Dr. Dan MacLellan, a dentist from Halifax, Nova Scotia, Canada, travelled to Bolivia to work as a volunteer with the IMIF dental program, with two major objectives. The first was to help the local dentists treat patients. Copious soft drink ingestion combined with lack of regular dental hygiene and dental care means that many people, especially children, have extensive dental caries. Because the people seldom seek treatment until they experience pain, extraction and the premature loss of teeth are often the result. IMIF dentists, however, have been working with people to prevent caries and preserve teeth. The second objective was to help improve and develop the IMIF dental program. This involved sharing current procedural techniques and treatment philosophies from Canada in an effort to increase preventative procedures and increase the local standards of care, especially in the more remote locations.
