Aberrant maxillary first molar mimicking mandibular first molar – An unusual case report

The tooth development involves a complex series of genetic interactions involving growth factors, transcription factors, signal receptors and diffusible morphogens that interact within independent signalling pathways. This report describes a case of occlusal dysmorphology and a root variance of maxillary right first molar which almost mimicked that of a rotated mandibular 1^st molar. The cuspal variation of mesiodistal was same as that of 36. This kind of variation may be due to Genetic or Environmental factors or interplay of both. So there is a need for research to be done in this aspect in larger group.
