Abstract

Growth in height and weight, oral hygiene and the emergence of permanent teeth in a cross-sectional sample of 509 Rajput boys and girls from the Kumarhatti and Dharampur areas of Solan District of Himachal Pradesh is reported. The data was collected from the various schools of the area. The girls were, by and large, taller and heavier than the boys; the differences were significant (P<0.05) at 12 years only. The oral hygiene of the sample was moderate and 15.28% children (9.76% boys and 5.52% girls) had one or more carious teeth. Mandibular teeth tended to emerge earlier than the maxillary teeth in both sexes. The emergence was earlier in girls, except the premolars. The bilateral differences were significant (P <= 0.05) only for maxillary central incisors and mandibular canines in girls and maxillary second incisors and canines and mandibular central incisors and second premolars in boys. The sequence of emergence in the first phase was the same (M1, M1, I1, I1, I2, I2) for both sexes. In the second phase of emergence, the maxillary canines emerged after the premolars in boys and after the first premolars but prior to the second premolars in girls. Partial correlations between number of emerged teeth and stature and weight were low and not significant, when the effect of age was partialed out. The emergence in the present sample was distinctly delayed in maxillary as well as mandibular first and second molars and mandibular lateral incisors as compared to a majority of other populations from within and outside India.
