Abstract

Background:  The premature loss of primary teeth may reduce arch length. Arch length is required for the eruption of permanent tooth and, if space is not available it predisposes crowding, rotation and impaction of the permanent teeth. The present study was conducted to assess the prevalence of early loss of primary molars in children aged 5-9 years. Material and methods: The present cross-sectional study was conducted among the 194 children aged between 5 and 9 years over the period of 6 months. All the relevant data such as age, gender, and missing teeth were recorded. The early loss was classified according to the chronological age table of eruption of the permanent teeth proposed by Kronfeld. The data was assessed using SPSS for windows release 21.0 (SPSS, Chicago, IL, USA).  Results: In the present study total sample size was 194 in which boys were 117 in number whereas 77 were girls. Maximum boys were of age group 7-8 yrs whereas maximum girls of 6-7 years age group. Overall maximum no. of children of age group 7-8 years. 1st primary molars were lost early than the 2nd primary molars. In boys both primary molars were lost more in no. than girls. Mandibular right primary molars were lost maximum in no. (35.05%) followed by mandibular left (22.16%). Conclusion: Our study concluded that the prevalence of early loss of primary teeth was present in predominantly in boys when compared to girls. The most commonly affected teeth were the mandibular teeth, the most common tooth being the first molar.
