An investigation of dental diseases in the highlands of Nepal was carried out in Langtang village (3, 500m elevation) from the middle to the end of March of 1992. The people of Langtang village were mostly of the Tamang tribe of Tibetan. This report is related to an epidemiorogical study of this particular tribe. The purpose of this investigation is to understand the dental diseases of Nepali people better. The results obtained were as follows : 1. As for the DMFT of permanent teeth, the DT increased from about 13 years old. Then at the age of over 60 years, it becomes 17.7. The MT is under 1.0 until 50 years old, but it increased dramatically at the age of over 50 years. The incidence of caries affection increased dramatically from about 13 years old and at this age the rate was over 60%. At the age of over 50 years, the incidence became 100%. The FT couldn't be observed. In comparison with the Japanese, the DMFT was very low and its progress was slow. Prior to this survey they received no dental treatments. 2. As for the attrition, attrition score 1 is observed at the ages of 10 to 12 years. According to the aging, number and degree of attrition increased dramatically. 3. The incidence of TMJ is very low in comparison with the people of Thecho village or the Japanese. 4. Few diseases of the soft tissue, except periodontal disease, could be observed. 5. Dental treatments in Langtang village conducted by us were mostly scalling and teeth extraction. We couldn't conduct other treatments, because we didn't have enough equipment and medical staff in there.
