Abstract

The crown enamel line of muroids rodent has geometric traces that coincide exactly with an equilateral triangular lattice. This finding helps to explain the muroids dental pattern from a novel perspective in molar morphology that it is based on hexagonal structures. The adult traces imply that the morphology of the teeth mammals is consequence of a morphogenetic process. This is the study of the hexagonal lattice marks observed in the enamel line, and therefore called odontohexasymmetry. The particular dental pattern, which it is passed down from parents to offspring, it start with a genetic algorithm coded in DNA. This includes a system of intelligent self-control, which during the morphogenesis coordinates the morphology of the all teeth of a specimen to get the best occlusion. The hypothesis of mitosis area loop-development (Ruiz Bustos, 2004a, 2005, 2006 and 2007) explains that in early morphogenesis stage, the initial mass-cell (basal mitosis area), it is repeated in a loop, thereby forming all other mitosis areas of the tooth. At the end of the morphogenesis, the biomineralization processes transform the mitosis areas in the cusps crown.
