The first permanent molar is one of the most important dental structures for the development of a physiologic occlusion and an adequate masticatory function; these teeth play an important role in the development and maintenance of an appropriate dental occlusion; they are very predisposed to dental caries after their eruption, around the age of 6 years. A cross-sectional, descriptive, observational study was carried out in the school Rene Fraga Moreno, of Colon municipality, province of Matanzas, with the aim of determining the first permanent molar lost in children aged 6-12 years, in the period from November 2012 to January 2013. The universe were 395 schoolchildren aged 6-12 years; the sample was composed by 41 children, with at least the lost of one of the four first molars. As a result there it was the prevalence of children aged 12 years, with the absence of the first molars, representing 31, 7 %; the male gender was the most represented one with 65, 8 %, and the 12 years age group presented 61, 5 % of students with inadequate buccal hygiene. We observed that 87, 8 % of the studied schoolchildren had a cariogenic diet; the more frequently absent first molar was the first right low molar with 60. 9 %. The male gender was the most affected by this disorder. The inadequate buccal hygiene predominated. The cariogenic diet prevailed in all ages. The first right low molar was the most frequently found lost in the mouth of these children.
