Every child in these communities has at least one cavity and most have already had multiple tooth extractions! It is urgent! YOU can make difference! The TIPNIS is a protected area and is one of Bolivia's most biologically diverse areas. It is home to the Moxeño, T'imane, and Yurakaré indigenous hunter-gatherer groups. The T'imanes we visited live in isolation on the banks of the Sérure river. This region is only accessible by bush planes and canoes with small engines. Medical and dental services are limited because of the difficult access, limited economic resources and language and cultural barriers (most of them speak only T'imane). Our upcoming project includes hands-on, culturally appropriate teaching in their native language and at their educational level. Topics covered will include avoiding sugar, brushing teeth and using fluoridated toothpaste. This program applies the principles described by David Neal and colleagues in their article the Science of Habit1 by using habits and nudges to develop long lasting behavioral changes. Self-efficacy will be increased. In addition, we will have with us dentists who can fill cavities and, if needed, extract teeth. Follow-ups with retraining are important for long term behavioral change and will be part of the project. 1. Neal D, Jelena, Hernandez O, Wood W.
