to the current day Tufts Dental School until the 1990s. The union was partially caused by the fire, and subsequent destruction of the USS Boston Floating Hospital (ID # 2366), a mobile hospital for sick children on Boston Harbor. In 1948, Tufts Medical and Dental College sold the Huntington Avenue buildings to Northeastern University, and relocated closer to NEMC at 136 Harrison Avenue. In 1954, Tufts Dental College became the "Tufts University School of Dental Medicine". The school would remain at the Harrison Avenue location until 1971, when it was moved to its current location of 1 Kneeland Street. The building was only 10 floors in height, but was designed with future expansion in mind. In 2009, the building was vertically expanded by 5 floors. This was seen by the architectural world as unprecedented; the design and execution has won several architectural awards. In 2013, the university announced plans to refurbish the third and fourth clinical floors, to match the newly renovated second floor. Admissions For the 2018-2019 application cycle, 4,094 applications were received for the 202 seats available in the Class of 2023. The DAT Academic Average was 20, and the Total Science was 20. While in the past international applicants were considered for admission to the School of Dental Medicine, for the 2012-2013 application cycle those applicants without US citizenship or permanent residency will not be considered for the DMD program. Student class profile There are approximately 4000 applicants each year and roughly 200 students enrolled per class, making it the second largest dental school in the United States. The Class of 2015 had an average age of 24; ranging from 21 to 38. The class was composed of students from 29 states. The School has over 7,000 alumni composed of individuals from all fifty states and thirty-nine countries. Nearly half of the Class of 2015 identifies as Asian (45%) and 49% of the Class is female.
