A better understanding of the factorsinfluencing tooth eruption is important given theassociation between altered eruption patterns andcrowded or decayed teeth. Hence, the aims of this studywere to quantify the extent of asymmetry in tooth eruptionand to determine whether eruption asymmetry wassignificantly influenced by sex, tooth position or timingof emergence. Additionally, directionality of asymmetryand variation between ethnic groups were also explored.Data collection was based on the examination of serialdental casts from a sample of 90 Aborigines (50 male, 40female) aged 6 to 18 years from the Yuendumu settlementin the Northern Territory of Australia. These casts wereobtained at yearly intervals from the 1950s to the early1970s. Tooth antimeres on each cast were compared usinga 4-grade eruption score. Relatively high (> 70%) interandintra-observer concordances confirmed reliabilityof the recording system. Asymmetry frequencies werecalculated and associations between variables assessedusing chi-square analyses, with statistical significanceset at alpha = 0.05. Evidence of patterned asymmetry forpermanent tooth eruption was noted among the sample ofAustralian Aborigines, with the distally positioned, laterformingteeth showing the highest levels of asymmetry
