The Study of Teeth eruption in Female Children of Malwa Region ? A Correlation with age

Background: Tooth eruption is a physiological process in which the tooth migrates from the maxillary bone towards the oral cavity, at the end of which teeth find their place on the arch creating vicinity relations according to a genetic code characteristic to each individual. Dental eruption begins with the eruption of the first primary teeth around 6 months and finishes at 2 years and a half for primary teeth, and around 18 ? 25 years for permanent teeth, when the third molar erupts. Aim: The teeth’s eruption and development is, usually, related to the child’s chronological age, but there can also be some variations. The aim of this study was to analyze the pattern of eruption of teeth, to define any variation in eruption of deciduous and permanent teeth. Material and methods: 500 female children from pre primary and primary Government schools, and Dental outpatient department within the age group of 0-12 years were randomly examined and range of time of eruption of teeth was calculated for central and lateral incisors, canines, premolars, 1st and 2nd molars, in both maxilla and mandible. Results: It was found that in case of deciduous teeth, in the study population, lateral incisors, canines and first molars erupted earlier in the upper jaw and the central incisors, and second molars erupted earlier in the lower jaw. In the case of permanent teeth all the teeth i.e. central incisors, lateral incisors, canines, first pre molars and second pre molars erupted earlier in lower jaw. Only the first and second molars erupted earlier in the upper jaw. Conclusion: Tooth eruption time and sequence are important factors in dental treatment planning, particularly in orthodontics, but also in forensic dentistry to estimate age of a child. It was concluded that the eruption of teeth was earlier in mandible (lower jaw) than in maxilla (upper jaw) in the case of permanent teeth.
