In most of the studies, the eruption of the mandibular teeth also occurs ahead of the maxillary teeth (Shaweesh 2012).
The aim of the present study was to evaluate the sequence of emergence of permanent teeth in children of Dakshina Kannada region of Southern India and compare our findings with those from other populations to identify the polymorphisms in eruption sequence.
The sample population assessed for this cross-sectional study was from 2536 students (1223 females and 1313 males) aged 4–16 years, attending schools in Dakshina Kannada District, Karnataka, India, that are being provided with community dental care by our dental institution.
The study was conducted after obtaining due consent and ethical clearance.
The first tooth to erupt in the entire dentition was the mandibular first molar (LM1), and the last tooth to erupt was the maxillary second molar (UM2).
Further, polymorphisms were observed more frequently in the sequence of emergence of mandibular teeth as compared to maxillary teeth.
This vast time period encompasses a host of variables most significantly, physiological (like heredity, constitution, geographic factors, sex, race, nutrition, stress, hormones), pathological systemic factors (systemic diseases and genetic disorders), pathological local factors (local impediments to eruption, hypodontia, lack of space), and the ambient influence of climate and food availability.
Several researchers in many areas of the world have studied the eruption patterns. in their textbook have documented that a study in Denmark (from Koch et al. 1991) has reported that Caucasians have a delayed time of eruption. With a current population of 1.2 billion people, India has been documented as hosting human civilization since at least the 7th millennium BCE.
This data was tabulated with their corresponding age and gender.The tabulation of age, gender, and dental eruption status was performed on the assumption that all children in the sample group belong to the same geographical region and share a common ancestry and are not racially diverse.
