Materials & Methods: A sample of 606 children (ages 3 to 8 years) was included in this study. The sample was taken from Norwood Pediatric Dentistry, Norwood, Massachusetts. The data collected included: age of subject, the presence/absence of midline deviation, the magnitude and side of deviation if present, the presence of a cross bite, and whether the patient had habits affecting dentition such as bruxism, tongue thrusting, mouth breathing, pacifier use, thumb or finger sucking, and nail or lip or cheek biting. Results: Midline deviation was recorded in 20.8% of the total number of visits, and it was found to be significantly higher in children with mixed dentition (30.7%) than in children with primary dentition (15.4%) (P < 0.0001). In children with first permanent molars erupted, 32.5% of children had midline deviation, which was significantly higher than the group of children who did not have their first permanent molars present (15.5%) (P < 0.0001). There was a statistically significant and positive association between age and midline deviation (P < 0.0001). At the last visit with primary teeth, 14.3% had midline deviation, compared to 24.5% at the first visit with mixed dentition stage. The difference between the two percentages was not statistically significant (P = 0.099). At the last visit with no permanent molars, 13.9% had midline deviation, compared to 24.4% at the first visit with a permanent molar. The difference between the two percentages was not statistically significant (P = 0.078). Conclusions: The prevalence of midline deviation in children in the mixed dentition stage is significantly higher than in children in the primary dentition stage. The prevalence was also higher in children with the first permanent molar erupted compared with children without the first permanent molar erupted. However, when following patients throughout transitioning from one developmental stage to another, it was found that there is no significant difference between the percentage of midline deviation at the last visit with primary teeth compared to the percentage of midline deviation at the first visit with mixed dentition stage. Moreover, there is no significant difference between the percentage of midline deviation at the last visit with no permanent molars and the percentage of midline deviation at the first visit with a permanent molar.; Thesis (M.S.)--Tufts University, 2016.; Submitted to the School of Dental Medicine.; Advisor: Noshir Mehta.; Committee: Matthew Finkelman, Britta Magnuson, and Nooruddin Pradhan.; Keyword: Dentistry. %[ 2022-10-12 %~ Tufts Digital Library %W Institution
