Emergence of the tooth, in simpler term is (means) the appearance of tooth in oral cavity through the gingiva. Emergence of permanent teeth has been studied among different population and among different ethnic groups. Standards for tooth emergence should be derived from the population in which they are to be applied because factors related to tooth emergence of both deciduous and permanent dentitions may vary among various races.


The clinical dental examination of the children was carried out in Brahmin, Chhetri, Rai and Limbu communities residing in Sunsari district of Eastern Nepal. A total of eight hundred fifty seven healthy children of pure races were included in the study. Children were grouped age. Sex and community wise. The following age groups were considered: 3.5-5years 6.5-8years, 9.5-11years and 15-16years.


The study result shows that the permanent teeth emerge and mature earlier in Rai and Limbu compared to Brahmin and Chhetri.


Our present study concludes that there is racial variation in emergence pattern of permanent teeth and there is need to conduct study on children of each and every ethnic communities.
