Introduction: Parents consider tooth eruption as an important event in the child’s development, and they have often showed their concern about the timing of eruption of teeth. Eruption time of the teeth and order are essential aspects in treatment planning, mainly when patients require orthodontic treatment, it also plays a pivotal role in forensic dentistry as it can help to find the age of an adolescent. Aims and objective: The basic aim of the study is to assess the eruption of permanent teeth with relation to age and body mass index among local population of Pakistan. Methodology of the study: This cross-sectional study was conducted at Mayo Hospital Lahore during March 2019 to December 2019. In this study we selected the participants of aged 10 to 15 years. The data were collected from 100 participants of both genders. Basic information such as educational level, date of birth, place of birth and family history was asked from students or taken from school records. Results: The data were collected from 100 children of both genders. Table 1 shows the descriptive statistics (number of cases, mean, median, standard deviation, and 95% confidence interval of mean) of eruption time of both the jaws and P-value for antagonist teeth (upper and lower corresponding teeth). The minimum mean eruption time was 6.5±1.1 years of right first molar of mandibular jaw (# 46). The maximum eruption time of 11.8 years was for the 2nd molars of maxillary jaw. Conclusion: It is concluded that there is no significant difference of eruption time between gender in all the studied teeth, except tooth #15, # 25 and #43.
