Changes in eruption pattern cause malocclusion and crowding, which lead to poor oral hygiene as well as periodontal disorders. Hence, it is important for the dentist to know the exact tooth eruption sequence to educate the parents. Tooth eruption sequence we follow is based on the Western population.
As Indian population differs from the Western population in ethnicity, racially, and dietary habits, etc., an attempt was undertaken to compare eruption sequence of Indian children in accordance with the Western population and also to correlate whether body mass index (BMI) affects tooth eruption.
Body mass index and eruption status of permanent mandibular central incisors and first molars were recorded among 529 schoolchildren in Chennai. Eruption status was examined with the help of mouth mirrors and illumination under natural light. The recorded data were entered into Microsoft Excel 2007 and were analyzed using Chi-square test, test, and Spearman's correlation test. Level of significance was set as 0.05.
Eruption values attained from our study were not consistent with the eruption values reported by Logan and Kronfeld. The present study showed that girls have early tooth eruption than boys. Our findings showed negative correlation with respect to BMI and eruption sequence of 31 ( = -0.133), 41 ( = -0.140), 36 ( = -0.08), and 46 ( = -0.076).
Eruption values reported by Logan and Kronfeld are inappropriate for Indian population. It is also found that obese children had delayed tooth eruption when compared with underweight children who had early tooth eruption.

萌出模式的改变会导致错牙合畸形和牙列拥挤，进而导致口腔卫生不良以及牙周疾病。因此，对于牙医来说，了解准确的牙齿萌出顺序以便对家长进行教育很重要。我们遵循的牙齿萌出顺序是基于西方人群的。
由于印度人群在种族、饮食习惯等方面与西方人群不同，因此尝试将印度儿童的萌出顺序与西方人群进行比较，并关联体重指数（BMI）是否影响牙齿萌出。
记录了钦奈529名学童的体重指数以及下颌恒中切牙和第一磨牙的萌出状况。在自然光下借助口镜和照明检查萌出状况。将记录的数据录入Microsoft Excel 2007，并使用卡方检验、检验和Spearman相关性检验进行分析。显著性水平设定为0.05。
我们研究获得的萌出值与Logan和Kronfeld报告的萌出值不一致。本研究表明女孩比男孩牙齿萌出更早。我们的研究结果显示，对于31颗牙（r = -0.133）、41颗牙（r = -0.140）、36颗牙（r = -0.08）和46颗牙（r = -0.076），BMI与萌出顺序呈负相关。
Logan和Kronfeld报告的萌出值不适用于印度人群。还发现与体重过轻且牙齿萌出早的儿童相比，肥胖儿童牙齿萌出延迟。
