Abstract
The mesiodistal crown width and occlusion in the deciduous dentition play a significant role in determining space and occlusion in the permanent dentition. Dental crowding occurs when the space required for the correct alignment of the teeth exceeds the space available in the dental arch, this usually results in rotated, ectopic, or impacted teeth. There have been many studies of the morphology of permanent teeth, a description of the morphological characteristics of deciduous molars is still lacking. The permanent first molar is the largest tooth of the oral cavity and the tooth of greatest biomechanical relevance. With regard to the deciduous second molar, it should be noted that this is the tooth with the largest mesio-distal diameter of the deciduous dentition. It is almost an exact copy of the permanent first molar, but of smaller size.
