To find the age of eruption of second permanent molar teeth among school children in Kuppam.
762 school children, studying and belonging to Kuppam, aged between 9 and 15 years were examined for the eruption of second permanent molar teeth after informed consent from the school authorities.
The mean age of eruption of right maxillary second permanent molar was 10.08 +/-0.55 years (males) and 12.9 +/- 1.2 years (females). For left maxillary second permanent molar, it was 10.36 +/- 0.71 years (males) and 12.74 +/- 1.02 (females). For right mandibular second permanent molar, it was 12.24 +/- 0.99 years (males) and 12.39 +/- 1.17 years (females). For left mandibular second permanent molar, it was 12.2 +/- 1.02 years (males) and 10.38 +/- 0.72 years (females).
As most prominent text books of Forensic Medicine in India give age of eruption of second permanent molars as "12 to 14 years" and considering the earlier age of eruption of second permanent molars in recent studies including ours, it is our suggestion that, many more studies may be conducted in different parts of India. This fact may be considered for revision in the textbooks.
