Human dentition is an intriguing area of study, providing insights into racial origins, oral health, and comparisons between contemporary and past populations. This study examines the permanent teeth eruption pattern among Bengali girls in Kalain, Cachar district of Assam. Data were collected from 208 school-going girls aged 5 to 15 years through oral examinations. The median age of tooth eruption was calculated using probit analysis. Results show that tooth eruption begins at age 5 with the first molars, followed by incisors at age 6. Approximately 78.9% of teeth had erupted by age 10. Complete eruption of permanent teeth (excluding third molars) was achieved by age 15. The findings also reveal that mandibular teeth generally erupt earlier than their maxillary counterparts. The eruption of permanent teeth in the study population follows a systematic pattern, with first molars appearing earliest and second molars last (third molars are excluded in this study). Our findings reveal similarities in teeth eruption patterns with some neighboring populations. This study highlights population-specific variations in dental development and contributes to understanding the growth patterns of permanent teeth in human populations.
